Description

汽车大灯注塑模具活动镶件强脱机构
技术领域
本实用新型涉及注塑模具，特别是涉及汽车大灯注塑模具活动镶件强脱机构。
背景技术
在汽车大灯的底壳上通常会制有线束卡子用于卡住车灯的电线，已有技术通常采用斜顶和滑块的配合脱出线束卡子，若线束卡子的卡块和卡槽相对，且两个位置相近，间距小，且模具内部的空间也较小，则无法采用斜顶脱模。
发明内容
本实用新型的目的是为了克服已有技术存在的缺点，提供一种汽车大灯被顶出时带动活动镶件一起向上，使线束卡子有弹性变形的空间，再将汽车大灯强行顶出，保证汽车大灯顺利脱模的汽车大灯注塑模具活动镶件强脱机构。
本实用新型汽车大灯注塑模具活动镶件强脱机构的技术方案是：包括下复板，下复板上设置模脚，模脚之间的下复板上设置上顶针板、下顶针板和顶针，模脚上设置型芯，型芯上设置侧抽芯滑块，侧抽芯滑块经油缸带动，在型芯上有汽车大灯，汽车大灯下制有线束卡子，其特征在于：所述的型芯中开有镶件孔，镶件孔与型芯底部相通，在镶件孔位于型芯底部设置堵头，镶件孔上开有头子孔，头子孔与型芯上部相通，在镶件孔中设置活动镶件，活动镶件底部制有挡板，活动镶件上端穿过头子孔与汽车大灯的线束卡子相配合。
本实用新型公开了一种汽车大灯注塑模具活动镶件强脱机构，当汽车大灯注塑成型后，模具开模，由上、下顶针板推动顶针向上，顶针将汽车大灯向上顶出型芯，由于此时汽车大灯的线束卡子仍与活动镶件相配合，因此汽车大灯带动活动镶件一起向上滑动，使线束卡子脱出型芯，当活动镶件底部的挡板与头子孔下端相接触时，头子孔的内孔径小于挡板的外径，挡板无法继续向上移动，挡板带动整个活动镶块停止向上移动，而顶针则继续向上推动汽车大灯，使汽车大灯的线束卡子强行脱出活动镶件的头部，完成脱模，而在模具合模后进行注塑时，通过注塑压力将活动镶件推动复位。本方案汽车大灯注塑模具活动镶件强脱机构，通过在型芯中设置活动镶件，利用活动镶件配合线束卡子，活动镶件头部与线束卡子一起脱出型芯，从而给线束卡子外侧留出弹性变形的空间，最后在塑料弹性的作用下将汽车大灯的线束卡子强行顶出脱模，保证产品顺利脱模。

具体实施方式
本实用新型涉及一种汽车大灯注塑模具活动镶件强脱机构，如图1—图3所示，包括下复板1，下复板上设置模脚2，模脚之间的下复板上设置上顶针板3、下顶针板4和顶针5，模脚上设置型芯6，型芯上设置侧抽芯滑块7，侧抽芯滑块经油缸8带动，在型芯上有汽车大灯，汽车大灯下制有线束卡子，其特征在于：所述的型芯5中开有镶件孔11，镶件孔与型芯6底部相通，在镶件孔位于型芯底部设置堵头12，镶件孔上开有头子孔13，头子孔与型芯上部相通，在镶件孔11中设置活动镶件14，活动镶件底部制有挡板15，活动镶件上端穿过头子孔13与汽车大灯9的线束卡子10相配合。当汽车大灯注塑成型后，模具开模，由上、下顶针板3、4推动顶针5向上，顶针将汽车大灯向上顶出型芯6，由于此时汽车大灯的线束卡子仍与活动镶件14相配合，因此汽车大灯带动活动镶件一起向上滑动，使线束卡子脱出型芯6，当活动镶件14底部的挡板15与头子孔13下端相接触时，头子孔的内孔径小于挡板的外径，挡板无法继续向上移动，挡板带动整个活动镶块14停止向上移动，而顶针5则继续向上推动汽车大灯，使汽车大灯的线束卡子强行脱出活动镶件14的头部，完成脱模，而在模具合模后进行注塑时，通过注塑压力将活动镶件14推动复位。本方案汽车大灯注塑模具活动镶件强脱机构，通过在型芯6中设置活动镶件14，利用活动镶件配合线束卡子，活动镶件14头部与线束卡子一起脱出型芯6，从而给线束卡子外侧留出弹性变形的空间，最后在塑料弹性的作用下将汽车大灯的线束卡子强行顶出脱模，保证产品顺利脱模。
