A three-color push and turn automatic forming mechanism

Abstract

This application relates to the field of injection molds, in particular to a three-color push and turn automatic molding mechanism. The main points of its technical solution are: including plate A, plate B, top core rotating assembly and rotating insert; plate A and plate B are opposite to each other, and there are first molding parts, second molding parts and The third molding part; the rotating insert is located between plate A and plate B, the rotating insert is provided with a fixed glue position insert, the first molding part and the fixed glue position insert are spliced ​​to form the first cavity, and the second The splicing of the molded part and the fixed glue position insert forms the second cavity, and the splicing of the third molded part and the fixed glue position insert forms the third cavity; the rotating insert is connected with the top core rotation assembly, and the top core rotation assembly It is used to drive the rotary insert closer to or farther away from the B plate, and the top core rotary assembly is used to drive the rotary insert to rotate. This application has the effect of improving the defect of long production cycle in the production process of three-color parts.

Description

technical field [0001] This application relates to the field of injection molds, in particular to a three-color push and turn automatic molding mechanism. Background technique [0002] Plastic products can be seen everywhere in daily life, especially in the medical industry. Plastic products are widely used in medical appliances. With the increasingly diverse needs of medical appliances, more and more different injection molding processes are required for molding. Among them, the three-color injection molding process is a production process that can reflect the diversity of medical appliances. Three-color injection molding refers to injecting three different plastic materials into the cavity of the mold, so that the parts are formed by injection molding of three materials. Various materials in the parts can have different colors or have different softness and hardness, so as to improve the aesthetics of the parts and improve the assembly performance of the parts.
