Die capable of steadily realizing retraction core pulling

Abstract

The invention provides a die capable of steadily realizing retraction core pulling, relating to the technical field of die equipment. The die comprises an upper die seat, a forming fixing block, a forming component, a retraction component, a fixed plate, a lower die seat, a thimble component, two angle pins, two side core pulling components and two spacer components, wherein the forming fixing block is used for playing a positioning role before parting for the forming component; the forming component and the retraction component are used for forming a product; a forming part does a retractionmotion approaching to the axle wire of a retraction guide block under the driving of a limiting part, so as to realize demoulding of the formed product; a thimble contacts with the top end of the inner surface of a forming workpiece, and in mould opening, a support spring is in a resilience state continuously to realize supporting and fixing of the forming workpiece after the thimble retracts in the retraction component. The die capable of steadily realizing retraction core pulling is simple in structure, can effectively form a workpiece with an internal buckle, and can realize steady supportof the workpiece after forming.

Description

technical field [0001] The invention relates to the technical field of mold equipment, in particular to a mold capable of stably realizing retraction and core extraction. Background technique [0002] Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to shape an article. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. [0003] However, when the size of some products is very small, and parts such as inner buckles are required inside the product, such as pen caps, cosmetic bottle caps and other calibration workpieces, the ordinary oblique and side-drawing core-pulling cannot be formed, and the round cap needs to be draw...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a mold capable of stably shrinking and core-pulling, which can effectively shape workpieces with inner buckles and realize stable support for the molded workpieces, and aims to improve the existing molds that can stably realize shrinking and core-pulling The technical problem is that the workpiece with complex structure cannot be formed quickly and effectively, and the molded workpiece cannot be ejected or supported for removal after demoulding
