Injection mold convenient to demold

Abstract

The injection mold comprises a bottom plate, a fixed mold block and an ejector plate, a plurality of first ejector pins and a plurality of second ejector pins are arranged on the ejector plate, the ends, away from the fixed mold block, of the second ejector pins are slidably connected with the ejector plate, a plurality of driving mechanisms are arranged on the ejector plate, and a touch rod is further arranged on the ejector plate. One end of the feeler lever is in linkage fit with the driving mechanism; during mold opening, the ejector plate moves towards the fixed mold block, the first ejector and the second ejector synchronously eject a product until the feeler lever abuts against the fixed mold block, the ejector plate continues to move, the feeler lever drives the driving mechanism to drive the second ejector to secondarily eject towards the fixed mold block, and the secondary ejection distance of the second ejector is larger than the moving distance of the ejector plate. The product is separated from the first ejector pin. According to the injection mold convenient to demold, a product can be quickly and completely demolded from the fixed mold and the ejector pin in sequence, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold for easy demoulding. Background technique [0002] Injection mold is a tool for producing plastic products, and 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. [0003] When demoulding injection molding products, it is usually necessary to use the ejector pin structure to realize the ejection and demoulding of the product. The demoulding mechanism of the existing mold in China generally first drives the ejection movement of the ejector pin through the ejector plate to drive the product to separate from the mold core...

AI Technical Summary

Problems solved by technology

[0003] When demoulding injection molding products, it is usually necessary to use the ejector pin structure to realize the ejection and demoulding of the product. The demoulding mechanism of the existing mold in China generally first drives the ejection movement of the ejector pin through the ejector plate to drive the product to separate from the mold core. When the product After being separated from the mold core for a certain distance, the product is picked up with the help of a robot, which is less efficient

In addition, although the current ejection mechanism realizes the separation of the product and the mold core, there may also be adhesion between the product and the end surface of the ejector pin, which will cause product damage when the robot picks up the product.
