A zinc alloy die-casting mold ejection mechanism

Abstract

The invention discloses a zinc alloy die-casting mold ejection mechanism, which comprises a fixed platen with a fixed mold core, a movable platen with a movable mold core, a movable mold lock plate, a push plate push block, a guide block, a limit pin and The latch, wherein, the movable mold locking plate is fixedly equipped with a push plate guide column, and the first push plate that passes through the push plate guide column is sequentially arranged on the said push plate guide column, and is fixed on the first push plate The first ejector plate on the top, the second push plate, the second ejector plate fixed on the second push plate, the first push plate, the first ejector plate, the second push plate and the The second ejector plate can slide up and down along the push plate guide post. The ejection mechanism of the zinc alloy die-casting mold of the present invention can effectively improve the products in the die-casting process, such as large clinging force, failure of the product to come out of the mold, poor die-casting, insufficient spraying, ejector pins and inserts breaking and cracking during the production process, etc. Phenomenon.

Description

technical field [0001] The invention relates to the field of alloy die-casting, in particular to a zinc alloy die-casting mold ejection mechanism. Background technique [0002] Mold is an important process equipment in industrial production. The mold industry is one of the important foundations for the development of various sectors of the national economy. For existing molds, the precision is low, the life is short, the manufacturing cycle is long, the molding equipment is relatively old, and there are few specifications and varieties. The research and development and application of mold materials are not strong, and the promotion and application of mold standard parts is still far behind industrial developed countries. Zinc alloy die-casting products are widely used, involving different fields such as aerospace, automobiles, medical care, and home appliances. Many products on the market are difficult to achieve mass production and high dimensional accuracy in the die-casti...

AI Technical Summary

Problems solved by technology

[0003] In view of the defects of the prior art, the purpose of the present invention is to provide a zinc alloy die-casting mold ejection mechanism, which has the characteristics of flexible application, high strength, wide application range, and is suitable for batch standard parts production. The structure can flexibly adjust the secondary, tertiary, and multiple ejection methods, and can completely decompose the characteristics of the product such as strong holding force, which can completely solve the problem that the product cannot be ejected during the zinc alloy die-casting process
