Abstract

The invention discloses an injection molding part sprue shearing method. The method comprises the following steps that, firstly, an injection mold is opened, four cup-shaped injection molding parts are formed at a time through the injection mold, the cup opening of each cup-shaped injection molding part faces downwards, and a sprue of each cup-shaped injection molding part is located in the center of the outer surface of the cup bottom; then, a material taking manipulator moves to the injection mold, a first suction assembly sucks the outer surfaces of the cup bottoms of the cup-shaped injection molding parts, and then the cup-shaped injection molding parts are taken out of the mold; and then, a transfer manipulator moves to the material taking manipulator, a second suction assembly sucks the inner surfaces of the cup bottoms of the cup-shaped injection molding parts, then the posture of the cup-shaped injection molding parts is adjusted to make the cup opening of the cup-shaped injection molding parts face upwards, the cup-shaped injection molding parts are transferred to a positioning mechanism to be positioned, and finally, the sprue of the cup-shaped injection molding parts is cut off through a shearing mechanism. According to the injection molding part sprue shearing method, the working efficiency is effectively improved, and the requirement of batch production is met.

Description

technical field [0001] The invention relates to a gate shearing method of an injection molded part. Background technique [0002] Injection molding is the process of injecting heat-melted material into the cavity through the runner and gate, and moving out of the mold after the material cools and solidifies to form an injection molded product with a certain shape and structure. Usually, after the injection molded product is out of the mold, there remains a gate connected to the injection molded part body in the flow channel of the injection port. Since the existence of the gate will affect the normal use of the injection molded part, it needs to be cut off. The traditional method of cutting the gate is manual cutting, that is, manually using gate pliers or blades to cut or cut off the gate connected to the injection molded part. This method has the following disadvantages: 1. Manual cutting is time-consuming and laborious, which is not conducive to assembly line industrial ...
