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 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.
