注塑模具带蜂窝状侧面竖板的二次抽芯机构
本专利技术涉及注塑模具,特别是涉及注塑模具带蜂窝状侧面竖板的二次抽芯机构。
技术介绍
在注塑模具中,若塑料件的侧壁制有竖板,且竖板的外壁上密布蜂窝槽、圆槽、方槽等结构,由于较多的槽会对侧抽芯滑块的包紧力较大,若采用侧抽芯滑块直接从侧面进行抽芯,则会导致侧抽芯滑块带动竖板一起移动,使竖板与塑料件主体之间拉断,造型产品报废,为了克服该缺陷,已有技术是在侧抽油缸的固定板上制有向上延伸的挡板,在侧抽芯滑块的后侧设置侧顶针板,侧顶针板上设置侧顶针,侧顶针穿过侧抽芯滑块与产品的部分蜂窝槽配合,侧顶针板与侧抽芯滑块之间有一定的间隙,侧顶针板与挡板之间设置弹簧,当模具开模时,由侧抽油缸带动侧抽芯滑块往外移动,但是由弹簧顶针侧顶针板、侧顶针保持不动,侧顶针顶住塑料件的竖板保持不动,使侧抽芯滑块先脱出竖板的蜂窝槽,该结构存在的缺点是:侧顶针板与挡板之间的间距较大,弹簧的弹力不足以支撑顶针板,容易导致注塑时,注塑压力过大,而使侧抽芯滑块往外侧移动,使模腔发生变化,并且模具开模,侧抽芯滑块往外移动时会带动顶针板一起移动,从而造成产品报废,并且需要增加侧抽芯滑块的厚度,本文档来自技高网...
