The present invention relates to a shoe sole molding apparatus invented to perform a process of automatically opening, closing and moving a mold for forming soles of sneakers and vulcanizing rubber.

The sole of the sneaker is mainly formed by placing the raw rubber in a mold having a predetermined shape and then heating and compressing the rubber.

According to the design, the sole may be molded in only one color, and in the case of forming a sole in which multiple layers have respective colors in a complex multicolor.

Conventionally, the following operations were performed to inject raw rubber into molds divided into upper, middle, and lower parts by a method of molding such sneaker soles.

First, the operator separates the upper and middle molds. At this time, since the molded rubber sole is positioned in a state in which the rubber sole is pressed, the mold can be separated only by applying more force than the surface pressing force together with its own weight during the separating operation by surface pressing.

Second, the rubber material is put into the separated mold, and the separated mold is assembled again. In this case, the input of materials does not require any special skills and forces, whereas the assembly of heavy molds in place requires a lot of power and skill.

Third, it moves to the working board position of the press machine in which a heater is installed. At this time, when moving to the position of the press work in the state that the heavy molds are combined, a lot of force and effort is required.

Fourth, the above-mentioned mold separation work, material input work, mold moving work, etc. are repeated, and a plurality of press machines are installed in parallel. Several press benches have already been installed vertically on the press, and the molds are repeatedly placed on the respective benches in order to press the molds simultaneously.

Fifth, press compression and heating work. That is, the molds located in the several work spaces are positioned below the molds, and the cylinders are moved upward to press the molds to squeeze the molds, and the molds are located inside the molds by heaters installed in the work benches. The prepared rubber material is allowed to heat for a certain time (about 150 ° C-200 ° C, 5-10 minutes).

Sixth, material replacement work. That is, after the above heating and pressing process is completed, the cylinders of the press are lowered, and the molds located in the respective working spaces are separated from the presses in order, and the above process of dismantling the molds and injecting materials again is repeated.

The soles completed by the above working processes are required by many workers in large-scale production plants, most of which are made by hand, and therefore require highly skilled and skilled workers; The problem is that the work is difficult and the fatigue is easily felt, and the work avoiding phenomenon occurs. Especially, in the hot summer season, the manual work performed in front of the hot press machine is more crowded, and the work avoiding phenomenon is severely induced. The production process of shoes was also disrupted. In addition, there is a drawback in that defective products are mass-produced due to the fact that the heating time and the like are determined by the operator's own experience, and there are various problems that affect the production cost.

The press part 100 is a structural part for molding the rubber material introduced into the mold into a sole form of a shoe desired by pressing and heating. As shown in FIG. 1, a cylinder 101 on which a piston 102 is operated up and down by an operation signal is located on a bottom surface of the press part 100, and a work board is installed to be movable in multiple stages from an upper portion thereof. Reduce or widen the gaps of 103. When the working plate 103 is press-molded by a single operation of the cylinder 101, a plurality of molds are installed to simultaneously compress the molds in consideration of its workability. In the present invention, three molds are provided once. Three working plates 103 are installed at regular intervals to be crimped at the same time by the operation of the cylinder 101, and the movement of the guide plate 105 vertically drilled on both side plates 104 is performed only up and down from the right position. The upper end of the press part 100 is made possible by integrally forming a fixed plate which does not move to the body to raise the working plate 103 and the mold located on the upper surface due to the rise of the piston 102 from the lower end, In addition, the molds positioned between the working plates 103 and the molds 10 positioned therebetween are raised by a method in which the mold positioned at the lowermost portion of the work plate 103 positioned in the middle is raised and the bottom surface is sequentially raised.It is compressed.

Inside the working plate 103, as shown in FIG. 1, a heater wire that is heated by supply of electricity is built in, or is compressed between the working plates 103 by allowing hot steam to be supplied from the outside. Heat is applied to the molds 10. The reason for heating the mold 10 is to fire the rubber material to be molded therein. Since the rubber material itself retains its elasticity at room temperature, even if it is pressurized with a strong external force, its shape cannot be deformed. It is necessary to maintain the degree to which the shape can be deformed at a small appropriate temperature. Therefore, the indirect delivery to the rubber material at a relatively high temperature of about 150 ° -200 ° C, and the heating and pressing time is about 5-10 minutes is appropriate, which is the same as the process of forming the sole by the conventional manual work.

The mold 10 is divided into an upper mold plate 11, an intermediate mold plate 12, and a lower mold plate 13, and the material located therein is located between the protrusions or grooves formed in the form of a shoe sole. It is the same as in the prior art to be singular in space. As shown in FIGS. 36 and 37, the mold 10 used in the present invention is symmetrical on both sides in the front center of the lower mold plate 13 so as to be caught by the moving means for automatic opening and closing. The ring plate body 20 is formed to be fixed using bolts, and rails l1a and 12a are provided on both sides of the upper mold plate 11, the middle mold plate 12, and the lower mold plate 13. 13a are formed integrally with each other so as to be guided when they are transported to the front for separation of molds, and when they are separated for input of materials, the rails 1la, 12a, and 13a are supported. The upper die plate 11, the middle die plate 12, the lower die plate 13 of the force applied to the separation to be transmitted. In addition, the middle portions of the upper mold plates 11 and the middle mold plates 12a and 12a are cut out so that the grooves 11b and 12b are dug up.

The piston end is fixed to the upper end of the support portion 271 so that the position is interrupted by the forward and backward motions of the second cylinder 212, which is mounted on both sides of the substrate 240, and the central operation plate 260 is By the forward and backward motions of the first cylinder 211 erected in the center of the substrate 240, the positions thereof were fixed to the end of the piston so as to move. And the upper operating plate 250 is fixed to the piston end of the other cylinder 251 that is built in the center of the lower operating plate 270, according to the operation instructions of the respective cylinders 211, 212, 251 The upper, middle, and lower operating plates 250, 260, 270 rise or fall as necessary and height. Here, the reason for operating the upper, middle, and lower operating plates 250, 260, 270 up and down is, first, in the case of the lower operating plate 270 is installed in three stages in the press unit 100 The positions of the plates 103 are different so as to transport the drawing and separating means of the mold 10 to their respective heights, and the central operating plate 260 supports the rail 11a as shown in FIG. In one state, the upper mold plate 11 is moved upward with the means for separating from the intermediate mold plate 12, and the operating plate 250 lowers the intermediate mold plate 12 of the mold 10. The movement is made by the cylinders in order to raise together the means for separating from the mold plate 13. The upper, middle, and lower operating plates 250, 260, and 270 are moved in position by the guidance of several posts 213 and 272 standing on the substrate 240 and the operating plate 270. To this end, the position of the posts (213), 272 is in contact with the bush so as to operate smoothly, the mounting positions of the cylinders 211 (212) (251) and posts (213) (272) Install them so that they do not overlap each other so that they do not interfere with each other.

The hook holder 470 is coupled to the inner and outer supports 420 and 410 by fixing bolts, respectively.

In addition, the inner and outer supports 420 and 410 are drilled with a predetermined length from the top to the bottom so that the upper end thereof is vertically oriented with an inclined surface 491, and then the spring 492 is internally Positioned at the bottom to install the operating shaft 490 to be elastic. The working shaft 490 is integrally extended with a bolt 494 having a relatively long length at the bottom thereof, and the working shaft 400 is coupled to the bracket 495 attached to the inside of the front plate 210 with a nut. ) So that it is vertically positioned.

The upper push link 430 and the lower push link 440 coupled to the pin holes 411 and 421 with pins on the inner support 420 and the outer support 410 are as shown in FIG. 32. The upper plate push link 430 and the lower plate push link 440 are connected to each other by the outer rotating links 431 and 441 and the rods 432 and 442 by rotating the inner and outer rotating links 431 and 441. ) To the top.

The lifting means of the upper push link 430 and the lower push link 440 is supported by the front plate 210 and the back plate 220 as shown in FIG. 30 and FIG. When the moving plate 450 is moved to the left and right by the fourth cylinder 452 by the guide of the, the upper plate push link 430 by the method of controlling the lower end of the rotary link (431, 441). And the lower plate push link 440 is lifted upward. That is, reinforcing pieces 453 and 454 having small diameter rollers 433 and 443 connected to the lower portions of the pivot links 431 and 441 to different installation positions on both sides of the movable plate 450. In the state in which it is fitted in the two grooves 453a and 454a which are vertically dug in the direction of the fourth cylinder 452, the moving pin 450 is rear from the front plate 210 of the body part 200. When moved to the plate 220 side, the rotary link 431, 441 moves to the same position as indicated by the virtual line at the position indicated by the solid line in FIG. 32 as a result of moving the lower portion, rod 432 The upper plate push link 430 and the lower plate push link 440 coupled to the pin 442 to be lifted.

The reason for lifting the upper push link 430 and the lower push link 440 is to separate the upper mold plate 11 and the middle mold plate 12 while the mold 10 is moved into the body portion 200. To do this.

The movable plate 450 is fixed to the piston end of the fourth cylinder 452 by screwing a bolt and a nut, and the movement is performed together. Dogs 452a are provided on both sides of the upper surface of the movable plate 450. After protruding, the lead switches sw4 and sw5 installed on the inner side of the front plate 210 and the inner side of the rear plate 220 are moved to make contact with each other to detect their movement, and then control the next progress signal. To (C). The reason for changing the attachment position of the reinforcing pieces 453 and 454 attached to both sides of the movable plate 450 is the rotation link 431 and 441 connected to the upper push link 430 and the lower push link 440. ), The reinforcing pieces (453, 454) in a state where it is commonly used to interlock the rollers 433, 443, the width is different depending on the position of the inner, outer support (420, 410). And the grooves 453a and 454a which are dug outwards thereof.

In the axial direction of the upper and lower mold push links 430 and 440, mold guide jaws 430a and 440a are formed long, as shown in FIG. 37, and the upper and middle mold plates 11 ( When the upper mold 11 and the intermediate mold 12 are lifted at the same time to guide the movement of the 12, the rails 11a protruding to both sides of the upper and middle mold plates 11 and 12 are formed long ( 12a) it is possible to separate the upper mold (11) and the intermediate mold (12).

In the middle of the upper plate push link 430, a groove about which the intermittent plate 435 can be installed is dug from the lower side to the upper side to install the intermittent plate 435, and then a bolt or the like is applied to the cover 485. Fix it at the bottom by using

The intermittent plate 435 is to guide the groove 436 to be guided by the guide projections (430b, 440b) having the lower plate push link 440 and the upper plate push link 430, respectively. On both sides of the rear end, the support jaw 437 is integrally formed with an intermittent plate 435 integrally coupled to the spring 438. A groove 486 having a size corresponding to the protrusion 439 protrudingly formed on the bottom of the intermittent plate 435 may be dug into the cover 485.

In addition, the cover 485 is formed at the center of one side of the operation part groove 486 to allow a plurality of bolt holes to be sequentially coupled to the upper push link 435 and the lower push link 440 as described above. The intermittent plate 435 performs the intermittent role of the hook 464 of the hook 460. In addition, both sides of the inner surface of the back plate 220, as shown in 30 to 31 of the needle drawing drawings, the link intermittent piece 401 is bound.

The auxiliary mold interrupting part 500 is a structural part for controlling the position of the auxiliary mold plate 14, which is separately installed into the inside of the Jinhang 10, when necessary to mold the shoe sole to be completed in a multi-colored collar when necessary to be.

Therefore, the purpose is to transmit the power to rotate the rotating shaft vertically located to the lower portion of the intermittent piece 392 to switch the position of the locking projection (392a) protruding to one side of the intermittent piece (392).

The stepping motor 510 and the gear box 520 are fixed to the front plate 210 and the rear plate 220 of the body part 200 using bolts using brackets on the upper surface of the fixing plate 370. Inside the gearbox 520, two pairs of bevel gears 521 and 522 driven together at the time of rotation of the motor shaft 511 are fixedly installed at both sides thereof so that the belt pulley 523 is located at the top thereof. 524). Two cams 512 and 513 are fixedly installed at the end of the motor shaft 511 so that the protruding surfaces of the caps 512 and 513 come into contact with the reed switch sw6 sw7 contacting one side thereof. Detects whether or not, and adjusts the driving angle. That is, when transmitting the power to rotate the locking projections 392a of the intermittent piece 392, without moving the locking projections 392a continuously, it is moved to a necessary position and can be stopped at that position. After rotating at an angle of, turn off the power and limit the number of revolutions to restore it back to its original position.

As shown in FIG. 18, the stepping motor 510 and the gearbox 520 installed on the right side of the fixed plate 370 are used to transmit power to the position of the gear 528 located in the middle of the upper and lower surfaces. The belt pulleys 523 and 524 and the pulleys 527 coaxially connected to the lower part of the gear 528 are connected to each other by the timing belt 525, and the same structure is located at both sides as shown in FIG. The other timing belt 526 is connected to the pulley to transmit the rotational force to the intermittent piece 392 of each of the locking projections 392a at the same time to move the position. The timing belt 525 cannot be directly connected to the other parts due to the position of the pulley 527, and a guide pulley 529 is installed in the middle thereof. The same structure is installed symmetrically up and down.

Therefore, the gear 528 received the power by the above method transmits the rotational force to the pinion 396 geared to it again, and the intermittent piece 392 connected to the coaxial shaft on the upper part thereof moves to protrude on one side thereof. The locking projections 392a are rotated to interrupt the separation of the mold.

The cover part 600 is a structure to prevent the scale and dust, etc. of the rubber materials falling from the top during the operation to fall into the body portion 200.

It is located on the inner top of the fixing plate 370 so that the covers of the multi-stage may be unfolded or folded together when the main slider 350 is moved. In the present invention, covers of the same structure that are separated into a predetermined size are installed to be separated into three stages.

As shown in FIGS. 15 to 16, the first cover 601 and the second cover 602 and the third cover 603 are separately formed, and then the first cover 601 is formed of the second and the second. The width of the first cover 601 is slightly larger than that of the third covers 602 and 603, and the second cover 602 is slightly larger than the third cover 603. To be positioned inward. Both ends of the first and second covers 601 and 602 are partially bent downward, so that the second cover 602 is installed on the upper surface of the front surface of the fixing plate 370, and the first cover 601 is installed. Is installed on the upper surface of the rear portion protrudes the locking jaw to the upper surface of the fixing plate 370, the first and second cover 601, 602 is installed to be intermittent.

Accordingly, the first, second, and third covers 601, 602, 603 have a function of being folded or unfolded while being folded as the main slider 350 moves forward and backward on the upper surface of the fixed plate 370. In the expanded state as well as in the folded state, the mold 10 is moved in the upper part, so that any residues, scales, and other dusts of the rubber material fall into the body part 200 and interfere with the overall operation. Prevent its life from being shortened.

Hereinafter will be described in more detail the effect according to the operating state of the present invention.

First, to accurately position the body portion 200 positioned in front of the press portion 100 to be worked and to prevent the flow of the body portion 200 during movement and separation of the mold 10, the positioning tool ( 280 is operated to accurately fix the position by the position fixing tool 189 and the lifting means 282 installed in the front of the press unit 100.

After the position fixing operation of the body portion 200 is finished, the third cylinder 353 moves the main slider 350 as shown in FIG. 25.

When the main slider 350 is moved, the intermediate slider 340 and the clamp body 310 positioned at the upper side are also simultaneously moved in the same direction of the main slide 350.

The reason is that the double speed gear 360, which is moved together with the movement of the main slider 350, is gear-coupled with the rack gear 382 fixed to the bottom of the slide guide 380 on one side, and the intermediate slider 340 on the other side. Since the main slider 350 moves forward, the slide double gears 110 on both sides move simultaneously, and the rack gears fixed at the fixed positions are moved. It rotates by the gear of 382).

Therefore, the intermediate slider 340 is rotated while the rotating double-speed gears 360 are rotated by the teeth of the fixed rack gear (382) and the feed force to push the moving rack gear 345 in the gear coupling state. To increase the moving force so that the gears can move the moving rack gear 345 in the advancing direction.

The clamp body 310 mounted on the upper part of the intermediate slider 340 is coupled to both bottom surfaces of two chains 334 so that the chain 334 when the main slider 350 and the intermediate slider 340 moves. ) Is to pull the clamp body 310 coupled to the upper direction.

As described above, when the main slider 350 and the intermediate slider 340 move the clamp body 310 in the direction of the press unit 100, the movement time is the same, but once the movement starts, the moving distance increases. .

In other words, when the main slider 350 moves 20 cm, the upper middle slider 340 moves 40 cm, and the uppermost clamp body 310 can move a distance doubled than the middle slider 340. Will be.

For example, the moving distance is 80cm from the start point of the clamp body 310 to the stop point, the distance the main slider 350 is to move 20cm, but the clamp body 310 operating at the top end is the same You can travel three times the distance in the running time.

Therefore, the main slider 350 operates in the limited space, but the clamp body 310 of the uppermost end simultaneously moves the distance increased three times in the same time so that the clamp body 310 stops at the same time when the operation of the main slider 350 stops. While the head portion 310a is already in the entry state into the space of the annular plate body 20, it is in the state immediately before pulling out the mold 10 placed on the working plate 103.

As described above, the start time and the stop time of each of the main slider 350, the intermediate slider 340, and the clamp body 310 are substantially made at the same time, but the moving distances are greatly different. At the time when the intermediate slider 340 is stopped, the clamp body 310 stops outside the position where the intermediate slider 340 is stopped. The reason why the ship moves the clamp body 310 is to enable the movement of the mold 10 even in the body portion 200 having a small width.

Therefore, as the clamp body 310 moves farther than the intermediate slider 340, the clamp body 310 is pulled back while compressing the spring 318a which is elastically installing the operating shaft 318 in contact with the end of the intermediate slider 340.

Therefore, the operation plate 320 is in a free state is the complete shaft 319, which is installed in the spring (319a) is backed by the elasticity, and at the same time push the operation plate 320 in the engaged state is located at both ends thereof The locking pin 321 is inserted into the groove of the pin intermittent ring 323b formed on the intermittent plate 323.

At the same time, the head portion 310a enters into the space portion of the ring plate body 20 coupled to the lower mold plate 13 of the mold 10, but at the same time the tension shaft 315 of the clamp body 310 is operated. The end portion is in contact with the front surface of the engaging protrusion 21, the tension shaft 315 enters the inside, and at this time the stopper 316 is also backed off to keep the intermittent plate 323 in a free state.

Simultaneously with the above operation, the head portion 310a enters the space of the ring plate body 20 as described above, and the fixing piece 311 enters into the locking protrusion 21.

Therefore, when the head part 310a completely enters the space of the ring plate body 20 while the clamp body 310 is stopped, the compressed spring 314a retracts the shaft 314 backed back by its elasticity. It will be made into the original position, and it will be in the state just before withdrawing the metal mold | die 10 in the state which the fixing piece 311 caught by the locking protrusion 21.

When the preparation for drawing out the mold 10 is completed, the control box C sends a signal of the ready state to the hydraulic unit O to generate hydraulic pressure in the third cylinder 353 which is already advanced, and thus the piston returns to its original position. To return to.

Accordingly, the main slider 350, the intermediate slider 340, and the clamp body 310 retreat while operating in the reverse order of the above-described forward operation.

When the clamp body 310 is retracted, the mold 10 caught by the fixing piece 21 is pulled out from the working plate 103 of the press part 100 to push the upper plate of the body part 200. The upper mold 11, the intermediate mold 12, and the lower mold 13 are moved to the link 430, the lower plate push link 440, and the lower plate mold guider 390 to be in a state of being ready to open and close the mold.

In this way, while the clamp body 310 is in the forward and backward operation, the switch dog 344 of the intermediate slider 340 is the control box (clamp body 310) to stop the signal according to the forward and backward control box ( To send to C), the lead switch sw1 (sw2) built in the slide guide 380 is brought into contact.

Therefore, the reed switch sw1 sends a signal of a ready state for drawing out, and the reed switch sw2 of the front side sends a signal of a mold opening and closing completion stop state to the control box C, thereby It will instruct operation.

As described above, after the clamp body 310 pulls the mold 10 out, the pistons of the second cylinder 212 and the first cylinder 211 are slightly raised to lower the operation plate 270 on the main shaft. The combined intermediate operation plate 260 and the upper operation plate 250 are raised to the lower operation plate 270 by the guide of the post, and are installed by combining the intermediate operation plate 260 and the upper operation plate 250 as a starting point. The inner and outer supports 420 and 410 on both sides and the upper push link 430 and the lower push link 440 coupled thereto are slightly raised at the same time.

At this time, the hook 460 provided at one upper end portion of the inner and outer support portions 420 and 410 has a hook 443 that is pushed to one side from the hook slide portion 473 of the hook holder 470. ), While the inner and outer supports 420 and 410 are raised, they are separated and opened to one side.

The reason for this is that the hook actuating pin 480 that compresses the compression spring 482 in contact with the mirror surface 491 of the actuating shaft 490 is off the inclined surface 491, and is coupled with the elastic force of the compression spring 482. Since the hook 460 is pushed out of the state, the hook ring 464 is released from the cover 485 in the state as illustrated in FIG. The link 440 is to be able to open apart.

At the same time, the reed switch sw3 is brought into contact with each other, and the spring 438 coalesced on the support jaw 437 formed by the rear portion of the intermittent plate 435 installed on the upper push link 430 and the lower push link 440. It slides out of momentum and pops forward at a certain distance.

Therefore, the stop can be stopped while moving only a certain distance as described above, the guide groove 481 slides in the guide projections (430b, 440b) protruding downward in the center of the letchet installation groove (430c) (440c) guide groove ( Since the guide protrusions 430b and 440b are caught by the 436, only the predetermined distance is restricted.

The protrusion 439 of the intermittent plate 435 is inserted into the grooves 11b and 12b cut in the middle of the upper mold plate 11 and the intermediate mold plate 12, and at the same time, the grooves 11b and 12b on both sides thereof. Both sides of the edge are coupled in the fitted state.

In addition, the inner and outer rollers 433 and 443 having lower ends of the inner and outer rotating links 431 and 441 at the same time as the above-described operation, the reinforcing pieces 453 coupled to both sides of the movable plate 450. Raised to fit in the grooves 453a and 454a which are dug out of 454, they are then inserted so that the open separation operation is ready.

Therefore, the reed switch sw3 sends the current operation ready state to the control box C. As a result, the fourth cylinder 452 is operated to move the piston to move the moving plate 450. , The inner and outer pivot links 431 and 441, i.e., the rollers 433 and 443 are moved from right to left, and the inner and outer pivot links 431 and 441 and rods 432 connected to the pins. ) So that the lower plate push link 440 and the upper plate push link 430 are separated.

Accordingly, the upper mold plate 11 and the intermediate mold plate 12 are separated and opened, and the intermediate mold 12 and the upper mold 11 in the vertically opened state are dropped because the intermittent plate 435 is interrupted. Is solved.

After separating and opening the intermediate mold 12 and the upper mold 11 as described above, the worker is already completed from the upper, middle, and lower mold plates 11, 12, 13 in the open separation state. The shoe sole is taken out artificially and then new materials are added.

After the rubber material is introduced, the intermediate operation plate 260 is lowered by lowering the same again in the state where the rubber material is slightly raised for the separation operation to the first cylinder 211 which is stopped in accordance with the working time.

Therefore, the rollers 433 and 443 fitted into the grooves 453a and 454a cut out of the reinforcing pieces 453 and 454 are lowered and then coupled to the link interrupting pieces 401 on both sides.

Therefore, the outer pivot link 431 is separated from the movable plate 450 and at the same time, the fourth cylinder 452 is operated to move backward in the state in which the movable plate 450 is moved forward. Since the return to the original position is coupled to the lower plate push-link 440 in the reverse order of the separated open state is coupled to the upper middle mold 12, the lower mold (13).

The fourth cylinder 452, which has completed the intermediate mold 12 coupling fixing as described above, moves forward again to push out the piston, and then moves the moving plate 450 again.

At this time, when the moving plate 450 is moved forward to the maximum distance, the dog 452a contacts the reed switch sw4, and thus the forward operation of the fourth cylinder 452 is stopped.

After the moving plate 450 which has been moved forward again stops, at the same time, the first cylinder 211 raises the outer support 410 on both sides, and the outer roller 433 is fitted into the groove 453. The dog 452a contacts the reed switch sw5 provided inside the front plate 210 while restoring the moving plate 450 advanced by the fourth cylinder 452. The upper, middle, and lower molds 12 which are in the open state by being separated by the upper plate push link 430 and the lower plate push link 440 which are stopped because the first cylinder 211 is lowered at the same time as the operation of the upper plate is stopped. (12) and (13) combine to form a combined mold (10).

Therefore, after the process of injecting the rubber material as described above to reshape the sole of the shoe is finished, the stopped third cylinder 353 is advanced in the same manner as it was first operated to pull out the mold 10. In this case, the intermediate slider 340 including the main slider 350 at this time and the clamp body 310 are repeatedly performed in the same state as described above so as to move, and the press unit 100 in which the mold 10 is initially located. The work plate 103 is placed again.

However, when the clamp body 310 moves forward while pushing the mold 10, the operation shaft 318 is backed as the first time, and the tension shaft 318 at the upper both sides is backed up as the first time, Tension shafts 315 on both sides are compressed to the front surface of the engaging protrusion 21 to retreat the stopper 316, and the intermittent pins 317 coupled to the both sides are stepped down to interrupt the intervening plate 323. Since it releases, the interruption | blocking board 323 will be in a free state, and the interruption board 323 will move around the hinge 324. As shown in FIG.

After the clamp body 310 is completely pushed the mold 10 into the working plate 103 in the above state, the third cylinder 353, which has been advanced, is reversed again to reverse the forward operation. In operation, the intermediate slider 340 including the main slider 350 and the clamp body 310 simultaneously retreat and return to their original positions.

Therefore, in the shaft 314 of the clamp body 310 in which the force is applied in the reverse direction, the intermittent plate 323 is separated downward, and the operation plate 320 also has the operation shaft 318 compressed backward. In the free state, both the buffer shafts 319 are pushed out of the operation plate 320 in a free state by the elastic force of the spring (319a) is compressed.

Therefore, the shaft 314 is pulled back with the both ends of the shaft pin 314b supported by the pushed operation plate 320, and the fixing pieces 311 of both sides connected to the links 312 to the shaft 314 are Since the inclined surface 311a is rotated to maintain a horizontal state, the fixing piece 311 is separated from the catching ring 21, and then the clamp body 310 is moved backward so that the mold 10 is placed on the working plate 103. It will be able to return to its original position.
