However, when the mold is pulled out or pushed while the catch is connected to the chain during the reverse operation in order to take out the mold and open it or separate it, the slide guide of the mold shakes left and right in an unstable state. When this occurs, the slide is moved, and since the upper mold is mounted on the roller having the support, the open separation is performed.

Therefore, the present invention has been improved so that the work can be carried out for multi-purpose regardless of the three-stage mold or two-stage mold, which is used in recent years, which will be described in detail with reference to the accompanying drawings.

As shown in detail in FIGS. 1 to 2, a rack 100 having a predetermined length is formed on the front surface of the press support shaft 2 of the press 1, and the outer surface of the rack 100 is provided on each side thereof. The elevator guide apparatus 101 is stuck.

Then, as shown in FIG. 1, the elevator 102 is formed, but as shown in FIG. 4, the body is formed with the frame 102a to have the elevator foot 102b, and the upper surface of the mold is taken out. In order to enable the opening and closing operation, the mold working plate 103 is fixedly installed.

Therefore, in the mold working plate 103, the ejector guide slot 103b and the unevenly formed slide guide 103a are formed in the center thereof, and the cylinder slot 103c is drilled on both sides thereof, and the drawing is made on one side. As illustrated in FIG. 7, the guide groove 103d and the guide shaft guide 103e are formed such that the turning cam 104 and the actuating cam 105 having a tapered surface on one side surface thereof are formed. The 105 is pivotally installed so that the spring 106 is installed on the bottom surface through the central portion thereof, and the mold taking out machine 107 is provided in the slide guide 103a of the mold working plate 103.

The mold extractor 107 is installed in a structure similar to that of the oyster patent application No. 9348 filed by the present applicant on June 30, 1989.

The mold ejector 107 structure is interlocked with the rack 107d through which the pinion 107b is penetrated into the head shaft 107c with a space 107a 'formed in the housing 107a. At one end of the head shaft 107c, a head portion 107g and a ratchet 107b are combined. In addition, the rack 107d is coalesced with a spring 107f by combining a guide shaft 107e on one side thereof.

In addition, the chain bracket 107i is coupled to the bottom of the housing 107a to connect the chain 108, and the chain 108 is interlocked with the sprocket 109 arranged on the front side and the rear side, and the starting motor Since it engages with the chain gear 110a of (11), according to the state in which the drawer motor 110 rotates forward and backward, the mold ejector 107 slides forward and backward.

In addition, on the upper surface of the mold working plate 103, that is, on both sides of the mounted mold ejector 107, a mold guide section 111 having a latching jaw 111a on the upper inner surface and a cylinder mounting portion 111b on the outer surface thereof. ) And fixedly installed, and the link guide plate 112 is fixedly installed on the upper surface of the mold guide 111 to the bolt shaft 114 having a gap adjusting piece 114a and a link having a ring 115a. The link bracket 113 combined with the 115 is combined with the support rod 116 so that both ends thereof are fixed to the link support plate 112.

In addition, in the cylinder long hole 103c of the mold working plate 103, a roller bracket 117b is formed at the end of the piston 117a, and an intermediate mold cylinder 117 in which the opening and closing roller 117c is combined is placed. The intermediate mold cylinder 117 installed is fixed to the roller frame 118 by forming a bracket 117d at the lower end thereof.

As shown in FIGS. 2 to 4, splines are formed on both sides of the gear shaft 121 on which the chain gear 119 and the bracket 120 are arranged to allow the pinion 122 to be built up. The gear shaft 121 is fixed to the bottom surface of the mold working plate 103 and the frame 102a by the bracket 120.

In addition, the chain gear 119 is configured to connect the lifting chain 123 with the chain gear 125 of the elevator motor 124 installed therein so as to transmit power, and the combined elevator 102, the frame 102a outer surface The master cover 126 is covered by a combination as shown in FIG.

After the elevator support plate 127 is formed on each side of the combined elevator 102 with the respective gear shaft holes, the guide roller shaft holes, and the guide roller shaft holes, the elevator support plate 127 with the guide roller shaft holes is formed. After the formation, the guide roller 128 and the elevator guide roller 129 are laid out and assembled on both sides of the elevator 102, and the gear shaft 121 protruding outward is fitted into the gear shaft hole and fastened with a nut.

At this time, the guide roller 128 is to be connected to the press support shaft (2a) having the annual side of the press (1), the elevator guide roller 129 is the elevator guide guide 101 formed on both sides of the rack (100) The elevator 102 is combined to be connected to the inner side.

Accordingly, in order to vulcanize the shoe sole, the power switch (not shown) of the control box 5 is turned on so that a proper heat of vulcanization is preserved in the pressurized heating plate 1a of the press 1.

After the power switch is operated, the heating plate 1a generates vulcanization heat by a built-in heater (not shown).

Since the set mold 4 is placed in the pressurized heating plate 1a in which heat is generated, vulcanization heat is received from the pressurized heating plate 1a.

Therefore, when a certain temperature is heated, the set mold 4 causes the piston of the rising press cylinder 5 to raise the compression heating plate 1a, and once the compression process is completed, the raised piston is lowered back to its original position. , The pressurized heating plate 1a, which has been press-compressed by each of the second and third floors, is also separated and returned to its original position by its own weight.

Therefore, the set mold 4 in the compression vulcanization completion state is pulled out by the pressurized heating plate 1a to separate and open the upper mold 4a and the middle mold 4b, and the finished product sole can be taken out therein. Will be.

Therefore, the present work is performed in a state in which a constant vulcanization crimping time according to the order in which the work is performed is input to the control box 5.

However, it is not necessarily operated by an automatic timer, and in some cases, manual operation is also possible.

After the vulcanization crimping process is terminated, the control box 5 is connected to the signal input motor 110, the switch (not shown) in the control box 5 is already connected to the input, accordingly, the drawer motor 110 is rotated in one direction The chain gear 110a of the motor shaft is rotated.

Therefore, the chain 108 engaged with the rotating chain gear 110a is slid to move the mold ejector 107 which is combined by being rotated in the state of being engaged with the sprockets 109 on both sides.

According to the above operation, the starting point of the mold ejector 107 moving forward in the direction of the press 1 is advanced from the position between the direction cam 104 and the actuating cam 105, so that the guide shaft guide 103e faces. The guide shaft 107e passes through the turning cam 104.

When going to the predetermined position, while the head portion 107a enters the space of the mold ring 130, the ratchet 107h on both sides hides in both sides while compressing the internally installed spring (not shown). It pops up again and becomes jammed.

Simultaneously with the above operation, the control box 5 again reverses the rotation direction of the drawer motor 110 and reverses the mold drawer 107.

Therefore, the mold extractor 107 is a ratchet (107h) of the head portion 107g is caught in the mold ring 130 to pull out the set mold 4 of the vulcanization completion state that is placed on the pressing heating plate (1a). do.

At this time, when the mold ejector 107 is reversed, the guide shaft 107e moves backward along the road that has progressed, while the inner surface of the operation cam 105 having the inclination in one direction by the spring 106 is moved. As it is pushed out, it rotates the operation cam 105.

Once the guide side 107e exits the inner surface of the actuating cam 105, at the same time, the actuated actuating cam 105 is returned to the elasticity of the spring 106 and tilted again in an oblique oblique direction. do.

In addition, of the set mold 4 drawn out by the mold ejector 107, both end surfaces of the fixed seat 4d on which the lower mold 4C is fixed are slide-moved while being guided by the mold guide 111. The mold 4a and the intermediate mold 4b are pulled out.

Therefore, the upper mold 4a has a link roller 115a inserted into the locking jaw 4a 'on both sides, and the middle mold 4b also has the opening and closing roller 117c at the locking jaw 4b' on both sides. Will be inserted.

Therefore, the upper mold 4a is lifted up and opened during the moving process, and the vertical mold 4b is closed at the position where the upper mold 4a is slightly pulled out while the upper mold 4a is opened. When connected to the inner side of 4b ', the piston 117' of the intermediate mold cylinder 117 is raised to push up the intermediate mold 4b.

However, during the process of opening and separating the upper mold 4a and the middle mold 4b, the slide movement of the mold ejector 107 is about the same time as the middle mold 4b is separated and opened. It will be in a completion state, and will stop at the end position of the mold work board 103.

Therefore, the upper mold (4a), the middle mold (4b), the lower mold (4c) is in a fully separated open state to take out the vulcanized shoe sole inside, the upper, middle, lower mold at this time (4a), (4b), (4c) is a state which is mutually engaged by the hinge part 4 'of the back part.

Then, after taking out the shoe sole from the open set mold 4, a rubber material (hereinafter referred to as a dough) in an unvulcanized state is inserted into the set set mold 4 to perform continuous vulcanization operation again. Re-cursion compression molding operation is performed, and after inserting the dough, the control box again rotates the takeout motor 110 forward. Therefore, the mold ejector 107 which has drawn out the set mold 4 is slid by the chain 108 which moves again and rotates, and the intermediate mold, which is raised at the same time as the mold ejector 107 starts to move, is raised. The piston 117 'of the cylinder 117 makes a downward movement.

The guide shaft 107e of the mold extractor 107, which moves to push the set mold 4 into the pressurized heating plate 1a, slides along the guide shaft guide 103e surface and reaches a predetermined position when the guide mold 107e is inclined. Rotated to the side to ride the outer side of the working cam 105 '.

In other words, the operation cam 105 inclined in the inclined state is the guide shaft 107e of the mold ejector 107 moving in the direction of the press 1 because one end surface is in close contact with the surface of the guide shaft guide 103e. The operation cam 105 is to move on the outer surface.

Therefore, the actuating cam 105 is rotated in a straight line in which the end of the wide open side is grounded on the tapered surface of one end of the turning cam 104 when the mold ejector 107 passes through a predetermined position. do.

Therefore, the guide shaft 107e is to be moved across the direction cam (104) using the working cam 105 in a straight line.

In the moving process, that is, from the moment when the guide shaft 107e rises to the operation cam 105, the combined rack 107d is moved in the same direction by the guide shaft 107e.

Accordingly, the engaged pinion 107b is rotated by the rack 107b in a state in which the pinion 107b is fixedly laid on the head shaft 107c, thereby causing the head shaft 107c to rotate.

Therefore, the head portion 107g for pushing the set mold 4 in the horizontal state inside the mold ring 130 is rotated and rotated 90 ° in the vertical state to push the set mold 4 to the pressurized heating plate 1a. Will be wit.

The state in which the set mold 4 is completely placed on the pressurized heating plate 1a is a state in which the movement of the mold ejector 107 is completely completed, and the guide shaft 107e is the direction change cam 104. The process of moving to the guide shaft guide 103e axis beyond the end is carried out, and at the same time the ejector motor 110 is reversely rotated to stop moving the mold ejector 107 to the original first starting point position.

Therefore, the rack 107d is gradually moved back to its original position by the spring 107f in the compressed state on one side, and at the same time, the rack 107d is gradually returned to the original position by the spring 107f in the compressed state on one side. The head 107c is rotated while the rack 107d is rotated at the same time, so that the head 107g, which was in the vertical state at the end thereof, is rotated 90 degrees in the horizontal state as in the initial state. It will be separated from the mold ring 130.

As described above, when the mold ejector 107 moves in the direction of the press 1, the piston 117 'of the intermediate mold cylinder 117 is lowered to its original position, and the intermediate mold 4b which has been separated and opened. And the upper mold 4a are combined again.

In more detail, when the mold ejector 107 moves forward, the set mold 4 in the separated open state is pushed in the direction of the press 1, and the upper mold 4a, which has been separated and opened while rotating with the force when it is taken out, is driven by its own weight. As it is lowered while being supported by the link roller 115a, the intermediate mold 4b is also lowered by its own weight as the piston 117 'of the intermediate mold cylinder 117 is lowered.

Therefore, the intermediate mold 4b and the upper mold 4a, which were separated and opened, combine the state of the lower mold 4c and the set mold 4 again.

Once again, when the set mold 4 is pulled out to the mold working plate 103, it is lifted open by being caught by the link roller 115a by the drawn force, but the upper mold 4a is pushed back in the reverse order. And the middle mold (4b) is to be closed according to the moving state because the force acting by its own weight.

As described above, after the vulcanization crimped set mold 4 is pulled out, the dough is put into the pressurized heating plate 1a of the press 1 to be re-refurbished again. The signal is sent to the lift motor switch (not shown) to operate the lift motor 124.

Therefore, the elevator motor 124 rotates the power of the gear shaft 121 through the elevating chain 123 and accordingly the pinion 122 rotates on the rack 106 to raise the elevator 102. Will let you.

At this time, the guide roller 128 is driven up and rides on the back, the press support shaft 2a, and the elevator guide roller 129 is driven up and down along the elevator guide guide 101.

The elevator 102 that rises as described above, the elevator motor 124 is stopped at the position where the second pressurized heating plate 1a 'and the height of the mold working plate 103 coincide with each other, and then the mold withdrawal opening and closing operation as described above is performed. do.

After completing a predetermined mold take-out opening and closing operation on the second pressurized heating plate 1a ', the elevator 102 again raises the third pressurized heating plate 1a "to perform the mold take-out opening and closing operation again, After the operation is completed in the pressurized heating plate 1a ", the elevator motor 124 is rotated so that the above-mentioned elevator 102 can descend to the original lower position, and is in an initial state.

As described above, the present invention enables a random operation as described above, so that manual operation and automatic operation are possible, and because the operator can carry out work on board the elevator 102, the second and third heights are increased. It is possible to compensate for the conventional loss of work time that had to be carried out by pulling down and lowering the mounted set mold (4), thereby increasing the output of the product and providing a cost-saving effect, regardless of gender. It is a useful design that makes it easy for female workers to work so that they can provide great help in eliminating manpower shortages.
