摘　　要：针对自动抽液保护瓶盖外观要求高、需脱螺纹及自动化生产要求,设计了1模4腔的二次顶出脱螺纹注射模。模具浇注系统采用普通流道与热流道相结合的结构,潜伏式浇口进料。用行星齿轮驱动4个管螺纹型芯联合脱螺纹方式,实现了塑件的自动化生产。模具结构合理,工作稳定,可为同类结构塑件的模具设计提供参考。For the high requirements of automatic pumping liquid protection lid appearance, and the requirements of thread demoulding and automated production, an injection mould with four cavities and twice ejection thread demoulding was designed. The gating system was adopted the combination of hot and cold runner with the latent gate feeding. It real- ized automatic production through planet gear to drive four pipe thread core to demould the thread. The mould structure was reasonable and it worked stably, which might provide the reference for similar structure of plastic parts.
