Description

f

The invention relates to the processing of polymeric materials and can be used to create a universal technological equipment.

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

Figure 1 shows the proposed unit, a plan view {in Figure 2 - semi-MatpHUbi; on fig.Z - section aa on figure 1 $ on-fig. 4 and 5 - clips on fig.b - block, longitudinal section.

Bpok contains fixed glita 1 associated with the holder 2, in which the semi-matrix 3 is installed, the movable plate 4 with the holder 5, in the grooves 6 of which the semi-matrix 7 is installed. The locking elements for fixing the semi-matrix 7 are made in the form of G-grips 8 installed in the grooves of the holder 5.

To secure the semi-matrix 3, the locking elements are made in the form of screws 9 interacting with the support. The semi-matrix 2 is installed with a semi-20 matrix 3, and the semi-matrix 7, attached with L-shaped grips 8, is attached to the semi-matrix. After installing the semi-matrix, the channels 12 are inserted in panv4I by sloping plots in semi-mat-25 zak 13. Next, the plates are installed

U, cooling and removal are made in the usual manner.

The cooling system is made in the form of channels 12 with fittings in semi-matrixes 3 and 7, while slots 13 are made in holders 2 and 5 for accommodating fittings therein.

Such a design solution expands the technological capabilities of the form, since it does not require precise

Corresponding to channels t2 in semi-matrixes to channels in holders, which makes it possible to use semi-matrices for a larger range of products, choosing the optimal arrangement of channels 12.

The unit is operated as follows.

In the holder 2, a half-matrix 3 is installed, and in the holder 5 - a semi-matrix 7, fixed with L-shaped grippers 8. After installing the semi-matrix, channels 12 are screwed into Jpits, which are located in the pa

U, cooling and removal are made by conventional means.
