剪切式切断浇口凝料的注射模结构设计

Design of the Injection Mold Structure with Cutting the Gate Sprue Through Shear

注射模结构类型和凝料的脱出方式因浇口形式的不同而不同。针对模外切断侧浇口凝料存在生产效率低,剪切质量差等问题,提出了模内剪切块式切断侧浇口凝料的注射模结构,并分析了其设计要点。

The injection mold structure and the sprue pulling type differs from the gate type.According to the low efficieney of cutting side gale sprue on the outside of die,and the poor quality of shearing,the injection mold structure with culting the side gate sprue using the shear block on the inside of die are proposed,and the design essentials are analyzed.
