分析了色拉油瓶盖侧面多处带有凸起、凹槽及内螺纹的成型工艺特点，介绍了一种成型该塑料件的注塑模具的设计方法。首先确定了模具的三板模结构，阐述了模具通过开模机构和二次推出机构，利用塑料件本身的弹性变形实现塑料件强制脱模。
分析瞭色拉油瓶蓋側麵多處帶有凸起、凹槽及內螺紋的成型工藝特點，介紹瞭一種成型該塑料件的註塑模具的設計方法。首先確定瞭模具的三闆模結構，闡述瞭模具通過開模機構和二次推齣機構，利用塑料件本身的彈性變形實現塑料件彊製脫模。

s:The molding process of salad cover with bump and inner thread was analyzed and its injection mold designing way was introduced. At first,the three-plate mold structure was set for salad cover,and then the flexible plastic part was enforced to pull out of mold by means of controlled parting order and designed secondary ejection mechanism.
