推杆直顶内抽芯结构注射模设计

Design of Injection Mold with Push Rod Straight Inside Core-Pulling Structure

介绍了塑件在必须使用内抽型芯成型,但内部空间较小,无法使用斜顶内抽的情况下所使用的一种抽芯结构:直顶内抽,并简述了与此结构配合使用的一种二次顶出机构。此结构实现了微型塑件内向抽芯动作的完成及塑件的顺利顶出,实现了生产中的自动化。

Products must be used in the plastic parts are introduced in the direction of the internal core-pulling, but inside the space is lesser, can＇t use under the condition of inclined top within the use of a core pulling structure： traight to the top and inward core-pulling; with this structure are briefly discussed and the use of a secondary ejection mechanism.This structure to achieve the completion of the micro parts inward core-pulling motions and smooth out of the plastic, realized the automation in production
