汽车空调鼓风机左右盖复杂抽芯注塑模设计
Design of complicated core pulling injection mold for left/right cover of car air tank
摘要
Abstract
According to the structural characteristics and technical requirements of the left/right cover car air tank,a large injection mold with a complex core-pulling mechanism was designed.The labor productivity increased by 10%,and the dimensional accuracy reached MT3(GB/T 14486-2008)through using a hot runner-gating system and a fast and bal-anced cooling system.The problem in the ejection system with a complex structure and multiple back buckles was solved by using composite core pulling and delayed core pulling.The accuracy and lifespan of the mold were greatly improved by using a guidance and positioning system with a standard ball-guide sleeve.关键词
