Zinc alloy die-casting die ejection mechanism

Abstract

The invention discloses a zinc alloy die-casting die ejection mechanism. The zinc alloy die-casting die ejection mechanism comprises a fixed die plate, a moving die plate, a moving die safety bar, a push plate push block, a guide block, a limiting pin and a plug pin, wherein a fixed core is installed on the fixed die plate, a moving core is installed on the moving die plate, a push plate guide post is fixedly installed on the moving die safety bar, a first push plate, a first ejector plate, a second push plate, and a second ejector plate are sequentially arranged on the push plate guide post, the first push plate penetrates through the push plate guide post, the first ejector plate is fixed on the first push plate, the second ejector plate is fixed on the second push plate, and the first push plate, the first ejector plate, the second push plate and the second ejector plate can slide up and down along the push plate guide post. By means of the zinc alloy die-casting die ejection mechanism, the phenomena that the clasp force is large, products are failed to be taken out of the die, die-casting is poor, and spray does not reach the designed position in the product die-casting process, and ejector rods and inserts are broken and pulled crack in the production process are effectively improved.

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
