摘要
介绍圆形盒体类塑件的整圈内侧凹槽在模具内成型、分型和2次内抽芯脱模的典型结构,模具生产的塑件合格,其结构对类似零件的设计有一定的借鉴作用。
A typical structure for the forming of a round box with an annular groove in interior circle was introduced. The mechanism of the injection mould, including the parting and demolding with twice inward core-pulling, was also discussed.
