Rotary disc type double-color injection mold forming process

Abstract

The invention provides a rotary disc type double-color injection mold forming process. A rotary disc, a male mold core, a first female mold core and a second female mold core are involved; movable mold bases which are symmetrically installed along the central axis of a double-color injection molding machine is combined with a fixed mold base through the forward movement of a guide column, a firstinjection pipe is used for injecting a PP material into a first mold cavity A, the material temperature is controlled to be 235 DEG C, the injection molding time is 17.5-20 seconds, then the mold is opened, after the rotary disc is rotated by 180 degrees, the mold is closed again, the first injection pipe is used for injecting the PP material into the first mold cavity A, the material temperatureis controlled to be 235 DEG C, and the injection molding time is 17.5-20 seconds. Through the improvement of a structure, the rotary disc type injection mold forming process is provided, and has the advantages that the process is continuous, the injection molding efficiency is improved, the connectivity among product melts is high, and the product quality is improved, so that the problems and defects brought in the prior art are effectively solved.

Description

technical field [0001] The invention relates to the technical field of injection molds, and more specifically, relates to a molding process of a turntable two-color injection mold. Background technique [0002] Two-color injection molding refers to the injection molding process in which different plastic melts or plastic melts of the same material but different colors enter the mold cavity successively or simultaneously to obtain plastic products with multiple materials or colors, so that different materials or different colors Colored plastics appear in the same product to achieve the purpose of being beautiful and making full use of the advantages and properties of various plastics. [0003] However, at present, the injection molding process of two-color injection molding products is still not perfect, which leads to the semi-finished products in the injection molding process needing to be disassembled and then reinstalled for injection molding, resulting in too complicate...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a turntable type two-color injection molding process to solve the problem that the current two-color injection products proposed in the above background technology still have an imperfect injection molding process during injection molding, resulting in semi-finished products that need to be disassembled and reinstalled during the injection molding process. For injection molding, the operation is too complicated and the product aesthetics is poor, which affects production efficiency. At the same time, there are problems and deficiencies such as poor contact between the melts in the product and affecting product quality.
