Abstract

一种模内镶件注塑模具的流道浇口结构，包括浇口、流道和膜片，浇口一端与模具型腔连通，另一端与流道连通，流道靠近浇口处采用扇形流道，膜片边沿位于流道上方，扇形流道上镶嵌有镶件，镶件为长条形结构，镶件的一侧与膜片边沿相抵接。该流道浇口结构，通过在流道浇口处设置镶件结构，替换传统IML模具中采用的滑块或斜顶结构，有效简化了现有模具结构，降低了流道重量，同时减少了塑料用量，降低了产品单价。

Description

一种模内镶件注塑模具的流道浇口结构
技术领域
本发明涉及模具技术领域，尤其涉及模内镶件注塑技术，具体的是一种模内镶件注塑模具的流道浇口结构。
背景技术
当前模具行业中使用的模内镶件注塑模具，为预防注射时融熔塑料从膜片侧面流入模腔冲走膜片，通常在模具上设计滑块或斜顶以实现流道反转，流道从滑块下面绕行流动，融熔塑料利用滑块阻挡反转流到膜片下面，有效解决了膜片被塑料冲走的问题，但这种模具结构复杂，模具制作成本高，同时流道需要设计的很大，造成注塑生产时塑料用量增加，进一步抬高了注塑产品的单价。
发明内容
本发明的目的在于克服现有技术存在的缺点，提供了一种模内镶件注塑模具的流道浇口结构，通过在流道浇口处设置镶件结构，替换传统IML模具中采用的滑块或斜顶结构，有效简化了现有模具结构，降低了流道重量，同时减少了塑料用量，降低了产品单价。
本发明的这种模内镶件注塑模具的流道浇口结构，包括浇口、流道和膜片，所述浇口一端与模具型腔连通，另一端与所述流道连通，其中，所述流道靠近浇口处采用扇形流道，所述膜片边沿位于所述扇形流道上方，所述扇形流道上镶嵌有镶件，所述镶件为长条形结构，所述镶件的一侧与所述膜片边沿相抵接。
进一步的，所述扇形流道的纵截面长50mm，高50mm。
进一步的，所述镶件底部采用与所述扇形流道相匹配的扇形结构。
本发明的工作原理是：注塑时融熔塑料通过流道和浇口进入模具型腔内，当融熔塑料经过扇形流道时，利用镶件的阻挡反转流到膜片下方，替代了传统流道靠滑块或斜顶实现的反转。
本发明和已有技术相比较，其效果是积极和明显的。本发明通过在流道浇口处设置镶件结构，替换传统IML模具中采用的滑块或斜顶结构，有效简化了现有模具结构，降低了流道重量，同时减少了塑料用量，降低了产品单价。
附图说明
图1是本发明的截面结构示意图。
图2是本发明的整体结构示意图。
具体实施方式
实施例1:
如图1和图2所示，本发明的这种模内镶件注塑模具的流道浇口结构，包括浇口1、流道2和膜片3，浇口1一端与模具型腔连通，另一端与流道2连通，流道2靠近浇口1处采用扇形流道201，膜片3边沿位于扇形流道201上方，扇形流道201上镶嵌有镶件4，镶件4为长条形结构，镶件4的一侧与膜片3边沿相抵接。
进一步的，扇形流道201的纵截面长50mm，高50mm。
进一步的，镶件4底部采用与扇形流道201相匹配的扇形结构401。
