Abstract

本实用新型公开了一种新型注塑模顶杆的改进结构,在顶杆顶端的推顶面的中央沿纵向向上凸起一凸台。由于本实用新型的顶面、与注塑件的接触面设有凸台,注塑件成型后,主流道上的废料会包裹在顶杆顶端的凸台上,凸台与流道中的废料接触面增大,与废料结合的较牢,使得该顶杆在脱模时,可将流道废料与注塑件分离而从流道、浇口中脱出。

Description

新型注塑模顶杆的改进结构
技术领域
本实用新型涉及一种塑料模具,特别是涉及一种新型注塑模顶杆的改进结构。
背景技术
在注塑件注塑成型后,注塑件从模具型腔中脱出,大都需采用顶出机构将其顶出。最常用的顶出机构就是顶杆,***面,这种顶面11’为平面的顶杆1’与注塑件10的结合度较低,不能满足将一些注塑件10从流道2’中抽出的需要。
实用新型内容
本实用新型的目的在于提供一种可与注塑件结合的较牢的新型注塑模顶杆的改进结构。
为实现上述目的,本实用新型的技术解决方案是:
本实用新型是一种新型注塑模顶杆的改进结构,在顶杆顶端的推顶面的中央沿纵向向上凸起一凸台。
所述的凸台为一个下大上小的锥形凸台,凸台的顶面为圆弧面或球面。
采用上述方案后,由于本实用新型的顶面、与注塑件的接触面设有凸台,注塑件成型后,主流道上的废料会包裹在顶杆顶端的凸台上,凸台与流道中的废料接触面增大,与废料结合的较牢,使得该顶杆在脱模时,可将流道废料与注塑件分离而从流道、浇口中脱出。
下面结合附图和具体实施例对本实用新型作进一步的说明。
附图说明
图1是习用顶杆结构图;
图2是本实用新型的结构图。
具体实施方式
如图2所示,本实用新型是一种新型注塑模顶杆的改进结构,在顶杆1顶端的推顶面11的中央沿纵向向上凸起一凸台12。
所述的凸台12为一个下大上小的锥形凸台,凸台12的顶面为圆弧面或球面。
本实用新型的重点就在于:在顶杆的顶面设有凸台。
以上所述,仅为本实用新型较佳实施例而已,顶杆凸台的形状可有多种,如方形、梯形等,故不能以此限定本实用新型实施的范围,即依本实用新型申请专利范围及说明书内容所作的等效变化与修饰,皆应仍属本实用新型专利涵盖的范围内。

Claims (2)

1.一种新型注塑模顶杆的改进结构,其特征在于:在顶杆顶端的推顶面的中央沿纵向向上凸起一凸台。
2.根据权利要求1所述的新型注塑模顶杆的改进结构,其特征在于:所述的凸台为一个下大上小的锥形凸台,凸台的顶面为圆弧面或球面。
