Description

一种锁片注塑成型模具
技术领域
本发明涉及一种模具 ,更具体的说是一种锁片注塑成型模具。 
背景技术
锁片是锁芯的重要组成零件,也是锁芯的易损件,频繁的转动需要锁片具有较好的质量和强度,也需要很高的精确度,以免锁芯卡死,传统的锁芯制作结构复杂,且精度不高,可能增加原材料的消耗,增加成本,影响企业效益 。
发明内容
本发明的目的是提供了一种锁片注塑成型模具,是根据对零件需求的实际情况制造而成的模具,不仅结构简单,可以实现批量生产,而且成品的精确度也很高。
本发明的技术方案如下:一种锁片注塑成型模具,包括上模、下模、浇口、圆形型腔、成孔销,所述上模和下模合模后形成圆形型腔,所述圆形型腔开设三个相同的扇环形凹陷,所述圆形型腔中间开设一个圆形开孔,所述成孔销垂直贯穿圆形型腔,插入所述圆形开孔。
本发明的一种注塑模具通过浇口将液体注入模具腔体,三个扇环凹陷使零件形成三个扇环凸起,成孔销在零件中心形成开孔。 
作为优选,所述圆形型腔外接一正方形型腔。
作为优选,所述正方形型腔与浇口相接,所述正方形型腔和浇口之间设有注浇通道。
作为优选,所述圆形型腔直径为45mm,所述正方形型腔边长为15mm。
作为优选,所述成孔销垂直贯穿圆形型腔,直径为15mm,所述成孔销圆心与所述圆形型腔圆心重合。
作为优选,所述扇环形凹陷内切于所述圆形型腔,将所述圆形型腔三等分。
作为优选,所述扇环形凹陷的内圆半径为30mm。
作为优选,所述下模内设有配合型腔起模的起模装置。
本发明具有以下有益效果:注塑模具结构简单,加工方便,大大缩短了注塑周期,节约了成本,提高了效率,企业可以批量生产,而且成品平整、美观,满足人们的需求。

实施例一
如图1、2和3所示,一种锁片注塑成型模具,包括上模1、下模2、浇口3、圆形型腔4、成孔销9,所述上模1和下模2合模后形成圆形型腔4,所述圆形型腔4开设三个相同的扇环形凹陷402,所述圆形型腔4中间开设一个圆形开孔401,所述成孔销9垂直贯穿圆形型腔4,插入所述圆形开孔401。
将注塑液从浇口3注入,通过注浇通道6进入正方形型腔5,再由正方形型腔5进入圆形型腔4,成孔销9贯穿圆形开孔401,注塑液逐渐形成3个相同的,等分圆周的凸起,中心形成一个直径为15mm的圆形开孔401,最终成型。
成型之后通过起模装置8将成品零件取出,完成一个注塑周期。
本具体实施例仅仅是对本发明的解释,其并不是对本发明的限制,本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造性贡献的修改,但只要在本发明的权利要求范围内都受到专利法的保护。
