Abstract

This invention relates to a technique for the processing of polymeric materials in:. articles, in particular for injection molds for the manufacture of long hollow articles. The goal is to increase the nesting shape, reduce its size, simplify the design and increase reliability. For this, the design slots 3 are arranged in two rows in a checkerboard pattern. Signs 10 of an additional row are mounted on the puller 6 and passed through the sign holder 7. Puller 6 and the sign holder 7 are wedged, and the slots under Htix 4, 5 in the movable 1 and fixed 2 plates are cone-shaped, which allow the puller 6 and sign holder to move 7, secured to the latter with the possibility of interaction with the ejection plate 9. The oblique columns 8 are fastened with strips 11, the ends of which are placed in the guide grooves 13 of the mobile half-form 1. 4 Il. g (L

Description

The invention relates to the processing of polymeric materials into articles, in particular to injection molds for the manufacture of long hollow articles.

The purpose of the invention is to increase the nesting shape, reduce its size, simplify and reduce reliability.

Figure 1 shows the shape in the closed state; FIG. 2 is a section A-A in FIG. one; FIG. 3 is a view B of FIG. one; in fig. 4 - the same at the time of disclosure.

The casting mold contains movable 1 and fixed 2 half-molds with decorating nests 3, arranged in two rows with displacement relative to each other in a staggered order, and conical grooves 4, 5, in which wedges, puller 6 and sign holder 7 are placed; with inclined columns 8 fixed on them, ejection plate 9 and signs 10 mounted on sign holder 7 and puller 6. Signs 10 fixed on sign holder 7 are passed through puller 6, and signs 10 fixed on puller 6 are passed through sign holder 7. Tilt Columns 8, mounted on the puller 6 and the sign holder 7, are fastened - with their own way by the slats 11, the ends 12 of which are placed in the guide grooves 13 of the movable half-form 1.

Casting form works as follows. After injection of polymeric material and technological latch

the form opens, the gating system 14 is separated from the products 16 by delays 15 and carried away by the movable part 1 due to the delay 17, the ejection plate 9 stops with the support of the injection molding machine, and the puller 6 with the sign holder 7 starts the sign holder with the sloping columns 8 with a sign located in the plane of the shape connector, and a puller mounted on the sign, inclined columns providing movement of the puller and 3 holder, an ejection plate, which is different in order to increase the nest i.formy.

get to the sides. In this case, the sprue-io sprue, imbalance simplification, system 14, at the expense of bevels 18, is pressed from the puller with the sign holder and falls down, and the products 16 collide with signs. When the form is closed, the puller with the sign holder is returned to its original position. The cycle is repeated.

The use of the proposed form allows to increase the nesting shape and reduce its size.
