Abstract

The invention provides a demoulding structure of an injection mold for a decorative panel on an automobile pillar, comprising a rear mold, a side core-pulling insert, a straight top insert and an obliquely drawing insert, the side core-pulling insert is installed on the rear mold, and The top insert is slidably installed on the rear mold, and the obliquely drawn insert is slidably installed on the rear mold through the guide slide seat. The end of the obliquely drawn insert penetrates the straight top insert; An ejector mechanism is installed on the lower side of the mold, and the ejector mechanism includes a thimble base plate, and a linkage mechanism is installed on the thimble base plate, and the straight ejector rod is connected with the ejection mechanism through the linkage mechanism. The demoulding structure of an injection mold for a decorative panel on an automobile pillar provided by the invention overcomes the defects of poor demoulding effect, complex demoulding structure, large space occupied by the mold and high mold manufacturing cost of the existing injection mold.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to a demoulding structure of an injection mold for a decorative panel on an automobile pillar. Background technique [0002] Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting heated and melted plastic into a mold cavity under high pressure from an injection molding machine, and after cooling and solidifying, a molded product is obtained. The injection mold mainly includes a front mold and a rear mold. The front mold is installed on the fixed seat plate of the injection molding machine, and the rear mold is installed on the movable seat plate of the injection molding machine. During injection molding, the front and rear molds are closed, and the plastic ...
