Abstract

Use: in the field of processing of polymeric materials into products, expands the technological capabilities of the universal unit. SUMMARY OF THE INVENTION: The unit contains fastening plates for the movable and stationary half-form and an ejecting system; on the ends of the attachment plates there are symmetrically mounted columns, on which the hinged slats are mounted so that they can be moved, the grooves with guides are made through 3 or more.

Description

The invention relates to the processing of polymeric materials into products, in particular, to universal blocks with interchangeable molds.

A known universal unit for the manufacture of plastic products on a thermoplastic steel machine, comprising a fixed plate and a fastening plate of one half-form, rigidly interconnected by means of a screw installed in the fixed plate, a movable plate and a support plate, interconnected by a screw the base plate, the second half-form fastening plate, placed on the base plate, guiding the sleeve and the column interacting with it, located on the movable plate, the mounting plates of the ejector system with installed and they kontrtolkatel E, clamps and molds and the ejection system.

In this block, the clamp is made in the form of a ring and spring-loaded shoes, movably mounted in the holder. In this connection, the installation of the half-molds into the block is carried out only unassembled, which complicates the change of the half-shapes in the block.

A known universal unit for the manufacture of plastic products on a thermoplastic automatic machine, comprising a fixed plate and a fastening plate of one half-form, rigidly interconnected by means of a screw mounted in the fixed plate, a movable plate and a supporting plate, interconnected by a screw mounted in the base plate, the second half-form fastening plate, placed on the base plate, guiding the sleeve and the column interacting with it, located on the movable plate, the mounting plate of the ejector system with mi mi kontrtolkatel them and pressing molds and the ejection system. The clamps are made in the form of hinged strips and U-shaped grooves located on the ends of the fastening plates, made on the surface of the plates under the protrusions of the half-molds, and the clamping of the ejector plates are made in the form of fastening plates located on the ends

folding strips and U-shaped grooves under ledges of plates of the pushing out system.

Due to the fact that the grooves with guides in a known universal block are U-shaped, such a block has limited technological capabilities, since it is impossible to use replaceable bags whose width exceeds the width of the universal block.

The aim of the invention is to expand the technological capabilities of the universal unit.

FIG. 1 shows a movable half-form of a universal block; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The universal block contains a fixed plate 1 and a plate 2 for fastening the fixed half-form, rigidly connected to each other, a plate 3 for fastening the movable half-form, placed on the base plate 4, a plate 5 for attaching the ejector system, placed on the removal plate 6, as well as clamps for the half-form and ejector system made in the form of grooves 7 with guides 8 and fastening flaps 9 fixed on the ends of plates 2, 3 and 5. Slots 7 guides 8 in plates 2 3. 5 fastenings are made through, and flaps 9 are movably mounted on columns 10, ra Placed at both ends of the plates 2, 3 and 5 fasteners and fixed fasteners 11.

The operation of the universal unit is carried out as follows.

Prior to installation into the replaceable package unit, the fastening elements 11 are twisted from the columns 10 placed on one of the sides of the unit, after which they are removed.

Tie folding strips 9, located on this side. By moving the fasteners 11 and moving the hinged bars 9 along the columns 10 located on the opposite side of the block, the universal block is adjusted depending on the width of the replacement package used. After the replacement package is installed in the grooves 7 with guides 8 made through in the fastening plates 2, 3 and 5, the replacement package is fastened using folding flaps 9 and fastening elements 11.

The use of the proposed technical solution allows to expand the technological capabilities of the universal unit, since it is possible to carry out work in a block of replaceable bags whose width is greater than the width of the block.
