汽车马鞍盖板注射成型冷却系统优化及模具设计
Optimization of cooling system and mold design for automobile saddle cover panel
摘要
Abstract
Moldflow software was used to simulate the injection process.The influences of the traditional cooling channel design and conformal cooling channel design of the mold cooling system on the cooling of product formation was com-pared and analyzed.The maximum temperature difference of the conformal cooling channel design between the product center and both sides was controlled within 4℃,which reduced the jacking cooling time by 17%and the total deforma-tion by 38.61%compared to that of the traditional cooling channel design.This resulted in the optimal cooling uniformi-ty of the mold with a conformal cooling channel.A hot runner injection mold of the conformal cooling channel was de-signed by using a inside and outside slider mechanism,an angle pin core-pulling mechanism,a lifter mechanism,and an"ejector pins pushing+ejector block pushing"mechanism.This design made the product released smoothly.The mold design was advanced,and the latch-style mechanism realized the order opening of two-plate injection mold,which could ensure the reliability of mold operation.关键词
