The Frictional Characteristic Analysis of Angular Cam in the Injection Molds;

The mould is designed to take advantage of slanted guide pillar with core pulling mechanism and ejector in Fixed Half to solve the problem of unloading the plastic parts with raised parts in side.

The slanted guide pillar, turntable and slide are adopted to accomplish circumferential multi-core lateral pulling action, and the common-used complicated gear-rack or connecting-rod structure are avoided.

A mould structure was designed to pull the cores at two layers toward different directions by using a slanted guide pillar.

Since the angle pin is a typical structural part of the mold,it is necessary to design automatically.

The molding of side holes was achieved by using angle pin and spring;the application of novel cooling system keeps the slim cores from affecting the layout of cooling system.

Aimed at the special surface shape of crosshead plastic parts, the mold with square-shaped slanting guidance pole, non-ejector, and side grading core-drawing structure is used, the mold structure is simple and efficient.
