内球类型芯注塑模脱模结构设计

Demoulding Structure Design of Inner Ball Type Core Injection Mold

对于内球形(内圆柱)类结构的塑料件,脱模处尺寸小于直径尺寸,需要设计内球形(内圆柱)类型芯脱模结构,解决顶出塑料件常有干涉现象或顶坏塑料件的问题,详细阐述几种结构的设计。经过生产实践,脱模结构设计能满足脱模需求,保证塑料件的质量。

For spherical （ cylindrical ） structure of the plastic parts, size of demoulding place was smaller than the diameter size, a spherical （ cylindrical ） type core demoulding structure was designed to solve the problems that any interference phenomenon occurred when ejecting plastic parts or ejecting plastic parts was failure. Several structural design was elaborated in detail. Through the production practice, the demoulding structure design could meet the demand of demoulding, ensure the quality of plastic parts.
