Abstract

The invention relates to a device for the manufacture of products from polymeric materials by injection molding. The purpose of the invention is to expand the technological capabilities of the mold for casting under pressure. The mold for injection molding contains a matrix 1, an ejector plate 2 with a tubular ejector 3 having side figured cuts 4, a rod 5 with a removable collar in the form of a pin 6 and a pressure plate 7 with a groove 8. When opening the form, the tubular ejector 3 acts on the sided figured slot 4 to a removable shoulder, made in the form of a pin 6, the pin 6 rotates in the groove 8 of the pressure plate 7, as a result of which the rod 5 rotates around its axis. Thus, when the resulting product is pushed, it separates from the rod 5. 3 Il.

j The purpose of the invention is to expand the technological capabilities of the mold for pressurizing.

FIG. Figure 1 shows the injection mold, longitudinal section, at the time of injection of the polymeric material; in fig. 2 - the same, at the moment of collision of the obtained product from the rod; in fig. 3 shows section A-A in FIG. one.

As a result, the rod 5 rotates around its axis. Thus, when the resulting product is pushed, it separates from the rod 5 by pushing the tubular pusher 3 and rotating the rod 5, thereby distributing the force applied to the product to be pushed.

The use of the invention will make it possible to achieve an economic effect by expanding the technological capabilities of the molds to be molded under pressure by providing the possibility of obtaining thin walled products from soft molds in the molds.

Curved notches 4, rod 5 15 and brittle materials and reducing the CJD removable shoulder in the form of a pin 6 and the thermal intensity of plastic products. Clamping plate 7 with a groove 8. The ejectable plate 2 of the plate 2 is provided with a shank 9.

The form works as follows.

After injection. In the form of the material (Fig. 1) and the required exposure time 20, the form is opened. During the development of the mold, the shank 9 rests on the yjnop of the injection molding machine, the pushing plate 2 with the tubular extractor 3 stops, and the matrix U 25 is grooved under the shoulder of the rod, which is associated with the pressure plate 7, continues That is, to expand the technology to move. In this case, the tubular pusher 3 acts by means of the side-shaped slits 4 on the removable shoulder, made in the form of a pin 6. Pin b
