Description

一种模具中的顶出稳定机构
技术领域
本实用新型属于模具技术领域，涉及一种模具中的顶出稳定机构。
背景技术
如图1所示为模具中常用的顶出结构，顶柱是通过模具中的顶柱孔进行运动的，当模具较大时，此种方式的顶柱孔无法加工出，加工精度不能保证，顶柱与顶柱孔的配合较差，易产生飞边，影响产品的加工质量。
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，耐磨性强，不易损坏的模具中的顶出稳定机构。
本实用新型解决上述技术问题所采用的技术方案为：一种模具中的顶出稳定机构，包括公模仁、顶柱、上顶板以及下顶板，所述的顶柱下端固定连接在上顶板上，顶柱的上端用于顶出产品，其特征是：所述的顶柱的外围套装有套筒，顶柱在顶出时沿着套筒内壁向上运动并顶出产品。
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顶出稳定机构中，所述的顶柱包括细头部和宽头部，所述的宽头部的横向宽度大于细头部。
在上述的一种模具中的顶出稳定机构中，所述的套筒与公模仁之间还设置有压板，所述的套筒通过压板固定在公模仁上。
在上述的一种模具中的顶出稳定机构中，所述的上顶板上设置有限位柱，在顶出产品时限位柱顶压在公模仁下端进行限位。
与现有技术相比，本实用新型的优点在于节约公模仁的加工时间，缩短了模具的制造周期；套筒材质硬度高，耐磨性强.不易损坏，加工精度有保证；顶柱与套筒配合加工，配合间隙较好，不易产生飞边，套筒为单独配件，方便维修及更换。
附图说明
图1是本实用新型的整体结构示意图。
图中，公模仁1；顶柱2；细头部2a；宽头部2b；上顶板3；下顶板4；套筒5；压板6；限位柱7；产品8。
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，本模具中的顶出稳定机构，包括公模仁1、顶柱2、上顶板3以及下顶板4，顶柱2下端固定连接在上顶板3上，顶柱2的上端用于顶出产品8。
顶柱2的外围套装有套筒5，套筒5与公模仁1之间还设置有压板6，套筒5通过压板6固定在公模仁1上，这里通过压板6固定一方面是为了保证顶出时的稳定性，另一方面是为了方便顶柱2拆装和维修。
顶柱2包括细头部2a和宽头部2b，宽头部2b的横向宽度大于细头部2a。这里细头部2a主要是为了方便将产品8顶出，宽头部2b主要是为了方便顶柱2运动，防止在运动的过程中折断；顶柱2在顶出时沿着套筒5内壁向上运动并顶出产品8，上顶板3上设置有限位柱7，在顶出产品8时限位柱7顶压在公模仁1下端进行限位。
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。
