Description

It is due to the high labor intensity and technological complexity of agonizing, which determines the relatively high eio consumer value.

The noted drawbacks are eliminated in the device for the production of aola.x. products made of elastic materials from Patent RU C1 2157317. In 29C 35/02,., which, according to the number of matching features and technical nature, was chosen as the closest AO aH.ajioi-a proposed.

The known device contains a mold, which has a vertical connector io forming the product, consisting of ioloforms fixed on the mounting plate, provided with coolant channels and connected to the drive cylinders, a closing movable cone, mounted on a parallel mounting plate, the product grips and a nozzle mounted on the rod of the ineval cylinder technological air supply

The geometrically closing yress-form cone is equipped with a power cylinder, and the forming upper plate interacts with the product grips fixed on the telescopic rod of the control cylinder of the central forming diaphragm connected to the supply system of technological steam and air.

The number of press mold connectors was minimized in this device, which ensured an increase in the quality of the molded commercial products due to the constructive control system for inflation and the synchronization of stepwise movement of tool rods for sequential molding of nojioio products of complex shape.

However, the known device for making hollow products from plastic materials by blowing a heated billet is characterized by extended working strokes of the actuators, which determines the choice of overall press equipment, which requires special room and maintenance, limiting its technical and io1 capabilities. Isolation.

In addition to TOio, equipment is additionally required to remove the flash, which increases the occupied production area, capital and material costs, increasing the consumer cost of 1 production.

The task to which the present utility model is directed is to develop a more functional, mobile, reliable, and more convenient in maintenance in ordinary production rooms device that constructively ensures the given quality of the molded products.

The required technical result is achieved by the fact that in the known device for making hollow products from plastic materials, containing a mold having a vertical connector along the generatrix of the product, consisting of half-forms mounted on the mounting plate, provided with coolant channels and connected to the drive cylinders, a closing movable cone mounted on a parallel mounting plate, the product captures and the nozzle for supplying technological air mounted on the rod of the pneumatic cylinder, at the suggestion of the author, the grips and the sections located under the technological air supply nozzle are rigidly assembled 1 with half-molds on mounting plates oriented along the clamping plane of the half-molds, and their drives are mounted on longitudinal peripheral positioning pneumatic cylinders, and the closing cone, which is aligned with the protrusions on the half-molds, is placed from two sides of the mold, each of which drive is mounted on the mounting plate, and then at the cut-out position of the formed product the clipping edge knives are movably mounted: 1 horizontally upper noy form and in the form of arches, konhruentnoy bottom surface of the article, of a double-edged band fixed to the rocker arm.

on how. uffekt. This amount is not representative of the signs of disunity, but not the sum of the sufferers, that is, achieving HOHOio supereffective when achieving a given technical O1o result.

The new constructive execution of actuators and their stable interconnection made it possible to distribute technological aspects of loading-molding-unloading in space, and to carry them out simultaneously, which does not affect performance, but simplifies the design of the device as a whole, autonomous adjustment and maintenance of eio structural component mechanisms .

At the same time, operations are iazionno combined: loading of the casing with a clamp of its bottom in the mold, molding of a bottle by blowing with a sealing clip 1 of the neck of the casing and loading of IOTOBOio from. with double-sided clipping.

The additional discharge position of the IOTOBOio product, in the grips interlocked with the ioliforms on the common mounting plates, ensured the placement of two special knives for cutting around the i-hole flange and the bottom of the formed container, which is carried out in parallel with the working time of the cycle. This extends the technological capabilities of the machine and reduces the cost of the product.

The location of the product grips on the plates common with the semi-molds, oriented along the plane of the mold connector, coaxially under the nozzle for supplying technological air, ensured plane-parallel action of the actuating mechanisms in the complex of technological transformations from blanking to IOTOBOio of the product.

The installation of parallel mounting plates on the longitudinal peripheral pneumatic cylinders freed up the working space and ensured settlement || consistent positioning of the actuators with double transfer of the workpiece along the mold connector plane for complete processing.

Press forms; coupled with nosti1 on .1form: with a slight K.ONICITY (about 3 degrees to the axis), that MHoio is greater than the friction angle of the materials to be corked - 15 1 degrees, additionally uniformly energizes the contact form by self-braking of these symmetrical aamkas, without individual power cylinders; that allows you to mount the cones on the common mounting plates.

A comparative analysis with identified analogues of the prior art does not explicitly follow from K.OTOpoio the proposed technical solution for a specialist in mechanical engineering, showed that it is not known, but taking into account the possibility of industrial reproduction of devices for manufacturing hollow products by blowing out of plastic materials, we can conclude that the criteria for patent about 11 about with about n about with about and.

The essence of the proposed utility model is illustrated in the drawing, where XEMATIChe

in FIG. - the proposed device, a view from above, on fi1.2 - conjio supply of technological air, in Fig.Z - the position of the clipping trim in the discharge unloading.

In figure 1, the images of various positions of the device are conventionally combined: on the left in the drawing, the initial position, on the right - in the closed position and the dashed line the second working position.

On the frame 1 (fi1.1) 1, the guide rods 2 of the peripheral positioning pneumatic cylinders 3 are fixed horizontally, on which drive cylinders 4 are mounted opposite to the center, bearing mounting plates 6 on the rods 5. The plates 7 are symmetrically mounted on the plates b, forming the mold in the aggregate for inflating plastic tubular casing for one-offs along the container profile, and capturing 8 formed products.

forms. BbiCTyiifci 9 1 od aamykayuschy cone 10, pivotally mounted HOBJieHHbiii on the rod e ii ii of the cylinder 12, rigidly connected to the mounting plate 6.

The half-molds 7 are equipped with circulation channels theilonosite.chn - cooling water (conventionally not shown in the drawing).

Above the grips 8 in the inlet of the mold connector, there is a movable COUJ1O 13 () mounted on the rod 14, which communicates with the compressed air supply system, the technological blowing agent. The rod 14 has a locking nut 15 for connection with the coil 13 and the drive cylinder 16 of the vertical reciprocating movements.

Behind the nozzle 13, at a distance equal to the distance between the axes of the half-molds 7 and grips 8, are installed (Fig.): At the height of the end 1 of the bottle neck in the grippers 8 there is a horizontal knife 17 and below it the swing axis 18 of the growling 19a 19 is not significant at the end of the arched double-edged knife 20 and 3 with t about l about 1 about polotna.

The knife 17 has a triangular shape, symmetrical to the longitudinal axis of the bottle in the clamps 8 at this position, and is equipped with a drive cylinder 2 1.

 19 of the knife 20 is pivotally connected to the rod 22 of the pneumatic cylinder 23 movably mounted on the frame 1. The knife 20 has a profile of the bottom of the bottle and mates with it when swinging along the plane of the connector clamps 8 (phi1.3) 5 in the groove of the slip 24 of the discharge.

The proposed device operates in parallel-serial mode as follows. Below is 1 {an example of sequential actions and transformations with a single hold-over to a TOTOBOI-O product, a bottle for ketchup is given.

the iO connecting cones are spaced apart and the position is relative to the semi-form 7, the nozzle 13 (feature 2) is raised to the irinod cylinder 16, the 1-oriental knife 17 is withdrawn from the closure plane (to the left but to the drawing), and 19 is in the extreme swing position

A piece tubular blank of yiuolyethylene or propylene, which has been found to be in an elastic state, in a specific example with a diameter of 30 mm and a wall thickness of 1.5 mm, is loaded into iodine-locked joints by the action of rods 5 of cylinders 4 through alites 6 and mold 7 in such a way that the lower end of the workpiece is wrinkled and tight between them is clamped.

Then, the rods 11 and 12 cylinders 12 cones on both sides of the mold are mounted on the combined openings 9 closed | oluform 7; 1eometric and force (due to self-braking) occurs, the closure of the irress form is almost monolithic.

At the same time, compressed air is passed in the cylinders 3, which are lowered to the lowest position (according to the drawing), thus moving 6.

Next, the nozzle 13 under the action of the rod 14 (fi1,2) of the cylinder 16 is lowered and self-installed inside the zotovka, crushing it but the profile of the inlet hole of the mold-form, thereby sealing the internal volume of the processed forging.

Then, the compressed technological air through the hollow rod 14 and the force 13 with a pressure of 4 ... 6 atmospheres is fed into the workpiece, inflating its walls along the mold-forming profile of the mold, the wall is thinned to a thickness of O, 3. . . ABOUT-. 5mm. This pressure is maintained for 4 ... 6 s with forced convective exhaust removal by means of water circulating in the half-mold channels 7 with a temperature of + 6 ... 10 1 degrees C to complete polymerization and structural transformations in the material and under active cooling. In the inflating step, the billet takes on a predetermined shape, and when cooling, the bearing strength of the packaging container structure, in particular, the bottle under the 0.5 liter ketchup,

After this is done, pressure inside the mold is relieved and the rods 11 of the in cylinders 12 are reversed and the self-locking cones 10 are returned to the initial position, releasing the combined nozzles 9 on both sides of the mold 7, and the 6 cylinders 4 are taken to the extreme position from the closing plane, releasing io.imer bottle, which 1 neckline is held on soil 13.

Then air is transferred in the cylinders 3, which, along the guide rods 2, lift the plates b with actuators up to their original position, while the grippers 8 are installed under the nozzle 13 opposite the molded bottle hanging on it.

In the next cycle of closure, the grippers 8 fix the bottle, and coiiJio 13 moves up the rod 14 of the cylinder 16; freeing her neck.

By feeding plates b to the extreme drawing according to the drawing, the bottle with grippers 8 is transferred to the discharge side 24, to the position of double-sided clipping of the flake (Fig. 3). Here, by the transverse movement of the horizontal knife 17 under the action of the drive cylinder A 21, the bottle’s half is cut to height at the level of thinning its walls during clamping in the mold of the blanking by the nozzle 13, and by reciprocating movements of the rod 22 of the pneumatic cylinder 23 with an arched knife 20, an obstruction is formed on the contiguous bottom of the bottle, formed by the clamp of the hook during loading in pushed half-forms 7; flush with two passes.

The distribution of the load on two inclinedly located cutting blades of the centrally mounted yen triangularly horizontal knife 17 reduces the elastic deformation of the thin walls of the neck, preventing breakage, chips, cracking5 which ensures the quality and accuracy of the cut in size at a given height of the bottle.

1 the required profile of the bottom ioner.ch.snoski of the bottle is ensured equal to the sharpening yijioM on both sides of the apoMHOio olora knife 20, which cuts off the groove during the cycle of swinging the lever 19 with the rod 22 of the cylinder 23; and then removes any remaining burrs.

When the mounting plates 6 are returned to their original position, the iodine that is open is driven by the drive cylinders 4 through the rods 5, the grippers 8 release the bottle, leaving a 1-piece product in the vicinity of 24 outlets. C.1 the plates move 6 to the lowermost position according to the drawing, closed clamps 8 push this IOTOBoe product ao skliz 24 for subsequent filling with 1 product and corking the container.

Thus, for each cycle of reciprocating movement of qi-1 indra 3 mounting plates 6 with actuators fixed to them, at one successive working position of the device, a 1-unit product is formed, because the operation of clamping the workpiece in half-molds 7, inflating it in a closed mold and cutoffs of the flake in grabs 8 on the slope 24 are carried out in parallel, combined, in time.

The proposed technical solution is a stable unity of design and functionality, provided by a set of essential features, KOTopoio actuators operate in parallel-sequentially and rigid mechanical connection of three working positions, equipped with autonomous drives with track control system.

The utility model provides a full cycle of automatic formation from a tubular blank of plastic small-piece packaging products of a predetermined profile of commercial quality.
