摘要:

根据汽车空调鼓风机左右盖结构特点设计了一副大型、复杂侧向抽芯注塑模具。模具采用热流道浇注系统以及快速和均衡的冷却系统,成型周期缩短了10 %,精度提高了一级,达到了MT3级(GB/T 14486—2008)。模具通过采用复合抽芯和延时抽芯有效解决了成型塑件结构复杂、倒扣多的脱模难题。模具导向定位系统采用标准滚珠导套,大大提高了模具的精度和寿命。

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 balanced 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.

Key words: left/right cover of car air tank, large injection mold, side core pulling mechanism, compound core pulling, time?delay core pulling, hot runner gating system
