Injection mold with linkage type undercut demolding mechanism

Abstract

The invention discloses an injection mold with a linkage type undercut demolding mechanism. The injection mold comprises a mold body, the mold body comprises an upper compound plate and a lower compound plate, a cavity is formed below the upper compound plate, a mold foot is arranged above the lower compound plate, a base plate is arranged on the mold foot, a mold core is arranged on the base plate, wherein the mold body is provided with a linkage type undercut demolding mechanism, the linkage type undercut demolding mechanism comprises a linkage type sequential mold opening assembly and an inclined ejection undercut removal mold outlet assembly, and between the mold opening action of the mold cavity-base plate and the mold opening action of the mold core-mold cavity, the inclined ejection undercut removal mold outlet assembly obliquely ejects out an undercut product to complete the undercut removal action. Through the cooperation of the linkage type sequential mold opening assembly and the inclined ejection undercut removal mold outlet assembly, it can be guaranteed that in the mold opening process, an inclined roadway of the inclined ejection undercut removal mold outlet assembly ejects out the undercut product to complete the undercut removal action and achieve demolding, and the production efficiency is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing, in particular to an injection mold with an interlocking undercut ejection mechanism. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. The advantages of the injection molding method are fast production speed, high efficiency, automatic operation, various designs and colors, simple to complex shapes, large to small sizes, accurate product sizes, easy replacement of products, and complex shapes. Parts, injection molding is suitable for mass production and complex shape products and other molding processing fields. [0003] Among them, in the injection molding of plastic products, the interior of some plastic product structures is usually provided with ring-shaped undercuts or indentations, and the plastic products cannot be taken out from the mold core by ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the difficulty that the existing injection mold mentioned in the background technology cannot realize the coordinated completion of the mold opening action and the knock-off type demoulding action, there are problems such as low production efficiency and high labor costs, the present invention provides a linkage type The injection mold of the reverse buckle ejection mechanism, through the cooperation of the linkage type sequential mold opening component and the inclined top release reverse buckle ejection component, only through the conventional mold opening procedure, can ensure that the inclined top falls off during the mold opening process. The buckle ejection mold component is inclined to eject the buckle product to complete the buckle-off action and realize the demoulding, which effectively simplifies the mold structure, reduces the manual process, and realizes the coherent action of mold opening-snapback-demolding, which significantly improves production efficiency
