Injection mold capable of preventing pouring gate from being sticky and operation method of injection mold

Abstract

The invention discloses an injection mold for preventing a pouring gate from being sticky and an operation method of the injection mold, relates to the technical field of injection molding production, and solves the problems that residual sticking at the pouring gate is likely to occur in the use of an existing injection mold, hard plastic particles are formed after the sticking is cooled, and the product quality defect is caused. The injection mold comprises an injection molding machine main body, a driving hydraulic cylinder, a cleaning swing arm, a swing arm linkage assembly and a cleaning assembly; the driving hydraulic cylinder is fixedly connected to the left end surface of the injection molding machine main body; the cleaning swing arm is rotationally connected to the bottom of a cleaning sliding seat; the swing arm linkage assembly is arranged at the rear part of the cleaning sliding seat; and the cleaning assembly is arranged at the end of the cleaning swing arm. The mold opening and closing actions are linked with the left and right sliding of the cleaning sliding seat, the pouring gate is effectively prevented from being sticky, the machining quality of products is guaranteed, the pouring gate can be cleaned in a linkage mode only through mold opening and closing, operation is easy, the control process is reduced, the structure is simpler, and occupied space is reduced.

Description

Technical field [0001] The present invention relates to the field of injection molding production, in particular to prevent injection molding molds of casting ports and their operational methods. Background technique [0002] Injection molding is a method of processing a plastic or rubber, and its working principle is to form a product of the desired shape by injection into the mold by injection by injection after injection of the plastic or rubber hot melt. [0003] For example, in one embodiment, the gate insert includes an injection gate body having a front and rear opposite side and a hole, the hole in the front side, an opening located on the rear side. The main body extends between the injection gate. The injection gate body can be attached to the front side of the gate pad and the front side of the cavity plate to the front side of the cavity plate and separated from it. In another embodiment, the cavity flange comprises a molded body defining at least a portion of the cav...

Problems solved by technology

[0005] The object of the present invention is to provide an injection mold and an operation method thereof for preventing the stickiness of the pouring port, so as to solve the problem that the existing injection mold proposed in the above-mentioned background technology is prone to residual stickiness at the pouring port during use, and hard plastic particles are formed after the sticky paste is cooled. When re-injecting, the plastic particles will follow the melt into the mold for molding. Since the melt is also cooling, the plastic particles are difficult to melt, and it is difficult for the plastic particles to fuse well with the melt, resulting in product quality defects.
