Abstract

本发明提供了一种改进的前模斜顶结构,可以使斜顶在离开产品后稳定脱扣,防止斜顶拉坏产品,其包括A板、B板、模仁、斜顶座、斜顶,所述斜顶座通过弹簧与所述A板连接,其特征在于:所述前模斜顶前端有倒扣面,所述模仁上固定有与所述倒扣面配合的拉块,所述倒扣面与所述拉块呈斜面配合。

Description

一种改进的前模斜顶结构
技术领域
本发明涉及浇注模具技术领域,具体为一种改进的前模斜顶结构。
背景技术
见图1,分模时,A板5运动,弹簧2压紧斜顶座3,使前模斜顶4只产生横向位移,但是有时由于弹簧2卡住了,前模斜顶4没有弹开,所以开模具时,当前模斜顶4还没有走出产品面1时,前模斜顶4跟着A板5走,拉坏产品1,前模斜顶运动不稳定。
发明内容
针对上述问题,本发明提供了一种改进的前模斜顶结构,使模具开模时前模斜顶只能产生横向位移,使斜顶稳定脱扣,防止产品拉坏。
其技术方案是这样的:一种改进的前模斜顶结构,其包括A板、B板、模仁、斜顶座、斜顶,所述斜顶座通过弹簧与所述A板连接,其特征在于:所述前模斜顶前端有倒扣面,所述模仁上固定有与所述倒扣面配合的拉块,所述倒扣面与所述拉块呈斜面配合。
本发明的上述结构中,由于采用了前模斜顶上的倒扣面和模仁上的拉块,开模时拉块可以暂时拉住前模斜顶,在前模斜顶离开产品面后,拉块放开前模斜顶,防止拉坏产品。
附图说明
图1为现有的前模斜顶结构示意图;
图2为本发明改进的前模斜顶结构示意图。
具体实施方式
见图2,本发明包括 A板7、B板9、模仁8、斜顶座3、前模斜顶4,斜顶座3通过弹簧2与A板7连接,前模斜顶4前端有倒扣面6,模仁8上固定有与倒扣面6配合的拉块5,倒扣面6与拉块5呈斜面配合,开模时,A板7运动,靠弹簧2的压力压住斜顶座3,使斜顶座3和与其连接的前模斜顶4不随A板7运动,同时拉块5通过前模斜顶4上的倒扣面6拉住前模斜顶4,由于弹簧2的压力压住斜顶座3,使前模斜顶4与产品分离,在前模斜顶4离开产品面后,前模斜顶4与拉块5分离、脱扣,从而防止拉坏产品,提高了模具的稳定性。
