Description

with an intermediate plate 6 of the product recovery unit and sprues, an oblique column 7, and the width of its protrusion 4 is less than the length of the distributing channel 8, the gating system. In the movable mold 1, there is a plate 9 with a pusher 10 and a spring-loaded ejector 11 of lithics. Formusyushch: a nolost is connected to the gating system by the inlet sprue 12.

The casting form works in the following way.

After making the product, the mold opens and when the plate 9 interacts with the fixed support of the injection molding machine, the pusher 10 pushes the finished product out of the mold. At the same time, the inlet sprues are detached from the product, since the insert 3 with its protrusions 4 overlaps the diluting channels 8, and the sprues remain in the base half-form 1. Upon further movement of the movable half-form 1, the plate 9 hits the intermediate plate 6, the tilted column 7 moves the insert 3 and the sprues are released. Upon further movement of the movable mold 1, plate 6 acts on a spring-loaded ejector and sprues and the mold is released from the sprues.

This solution improves the reliability of the form.
