一种滑块顶出倒扣结构及模具

Abstract

本实用新型公开了一种滑块顶出倒扣结构及模具，涉及注塑技术领域。包括相对设置且可相互靠近或远离的两个成型件，二者相对端设有成型部；每个成型件对应一组滑动组件，滑动组件与成型件联动，包括与成型件固定连接且和后模板滑动连接的滑块。成型部含注塑空腔和注塑通道，两成型件拼合时注塑空腔形成对应至少一个产品的空腔结构，注塑通道与后模仁分流道连通。本实用新型通过特殊成型件结构完成带倒扣结构的小型零部件注塑，成型件兼具倒扣成型与活动模具功能，在常规前模和后模间形成针对小型零部件的注塑结构组合，与常规模具共同运作，无需额外配置动力和注塑材料供给通路，可增强注塑加工灵活性，提高生产效率。
