Abstract

本实用新型属于模具技术领域，提供一种模具中的双滑块顶出机构，包括公模板、母模板以及顶杆，母模板上设置有顶板，顶杆的下端安装在顶板上，顶杆上端上设置有滑块座，产品放置在滑块座上，在滑块座内分别设置有左滑块和右滑块，在左滑块和右滑块之间设置有弹簧，当模具顶出时顶杆推动滑块座顶出，在弹簧的作用下，左滑块和右滑块弹开到指定位置并将产品倒勾顺利顶出。本实用新型的优点在于结构简单，安装方便，采用双滑块将产品顶出，优化了顶出机构，降低成本，提高模具品质，解决了一般顶杆容易断裂咬合的问题。

Description

一种模具中的双滑块顶出机构
技术领域
本实用新型属于模具技术领域，涉及一种模具中的双滑块顶出机构。
背景技术
现有模具中的结构为哈夫顶出机构，在顶出的过程中会产生侧向的移动完成侧抽芯，当采用常用的顶出机构时，由于在顶出时顶杆会产生力矩，当角度变大时力矩会变大，当角度达到一定值时，在运动过程中顶杆很容易被拉断或者咬合卡死，且机构的加工和装配复杂，成本高。
发明内容
本实用新型所要解决的技术问题是针对现有技术的现状，而提供一种结构简单，装配方便的模具中的双滑块顶出机构。
本实用新型解决上述技术问题所采用的技术方案为：一种模具中的双滑块顶出机构，包括公模板、母模板以及顶杆，所述的母模板上设置有顶板，顶杆的下端安装在顶板上，其特征是：所述的顶杆上端上设置有滑块座，产品放置在滑块座上，在滑块座内分别设置有左滑块和右滑块，在左滑块和右滑块之间设置有弹簧，当模具顶出时顶杆推动滑块座顶出，在弹簧的作用下，左滑块和右滑块弹开到指定位置并将产品倒勾顺利顶出。
为优化上述方案采取的措施具体包括：
在上述的一种模具中的双滑块顶出机构中，所述的滑块座上分别设置有左限位销和右限位销，左滑块和右滑块分别通过左限位销和右限位销锁定限位。
在上述的一种模具中双滑块顶出机构中，所述的顶杆下端与顶板之间设置锁定螺丝，顶杆通过锁定螺丝与顶板固定连接，所述的顶杆上端与滑块座之间设置有定位销，滑块座通过定位销与顶杆固定连接。
与现有技术相比，本实用新型的优点在于结构简单，安装方便，采用双滑块将产品顶出，优化了顶出机构，降低成本，提高模具品质，解决了一般顶杆容易断裂咬合的问题。
附图说明
图1是本实用新型的整体结构示意图。
图中，公模板1；母模板2；顶杆3；顶板4；锁定螺丝5；滑块座6；定位销7；左滑块8；右滑块9；弹簧10；左限位销11；右限位销12；产品13。
具体实施方式
以下是本实用新型的具体实施例并结合附图，对本实用新型的技术方案作进一步的描述，但本实用新型并不限于这些实施例。
如图1所示，本模具中的双滑块顶出机构，包括公模板1、母模板2以及顶杆3，母模板2上设置有顶板4，顶杆3的下端安装在顶板4上，顶杆3下端与顶板4之间设置锁定螺丝5，顶杆3通过锁定螺丝5与顶板4固定连接，这样在开模时就可以通过顶板4带动顶杆3向上顶出产品13。
顶杆3上端上设置有滑块座6，顶杆3上端与滑块座6之间设置有定位销7，滑块座6通过定位销7与顶杆3固定连接，产品13放置在滑块座6上，在滑块座6内分别设置有左滑块8和右滑块9，在左滑块8和右滑块9之间设置有弹簧10，滑块座6上分别设置有左限位销11和右限位销12，左滑块8和右滑块9分别通过左限位销11和右限位销12锁定限位。
工作时在合模状态下，左滑块8和右滑块9处于合并状态，在滑块座6内，滑块座6在公模板1中。当模具向上顶出时，顶杆3推动滑块座6顶出，在弹簧10、左限位销11和右限位销12的共同作用下，左滑块8和右滑块9弹开到指定位置，产品13倒勾顺利脱开，模具回位时，顶杆3拉动滑块座6退回公模板1内，左滑块8和右滑块9在模仁侧壁的作用下重新滑入滑块座6内，两滑块靠紧为下一次顶出做准备。
本文中所描述的具体实施例仅仅是对本实用新型精神作举例说明。本实用新型所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本实用新型的精神所定义的范围。
