GATE-浇口设计

注塑模具浇口的设计方法浇口等的相关位置图4.1. 浇口等的相关位置注道(sprue)流道(runner)浇口(gate) 阴模(cavity) 滞料部(cold slugwell) 的相关位置如图4.1所示。

流道横截面形状有圆形，半圆，梯形。

圆形是流动阻碍力是最小也是最普遍的一种。

表4.1中显示了圆形流道的直径和长度以及产品厚度的关系。

关于半圆形和梯形流道的深度h和宽度W、B、半径r之间的关系如图4.2所示。

浇口种类浇口横截面形状种类图4.3. 浇口横截面形状种类浇口位置的选择Ⅰ. 根据产品性能∙设计：外观上无浇口印迹，即使留有加工印迹也要在不明显的位置。

∙尺寸精度：加工齿轮，轴承等对圆形要求十分重视的成型品时，需要将成型材从中心注入。

尺寸精度要求严格的部分不能装置浇口。

∙强度：推断熔接线产生的位置，评估强度如何。

如若有问题就改变浇口位置。

Ⅱ. 根据模具数量是单个还是多个组成流道，阴模配置，聚合物的注塑压力所导致开模压力仍是否平衡等。

如果开模压力过于集中，则会产生应变，模具会歪曲。

Ⅲ. 根据加工的所需的经济性是否采用模具需要分成三部分的点浇口，还是采用不要加工的沉陷式浇口,还是进行普通浇口。

Ⅳ. 根据材料成型性材料的流动性，耐热变色性，成型应变等来决定浇口的种类和浇口的位置。

浇口平衡性熔融聚合物一般可以全部同时打到阴模上的浇口处，所以必须设计阴模能够同时被聚合物填满。

浇口平衡性差的情况下，会发生留痕，凹痕等外观问题，且各成型品中会存在强度差异。

Ⅰ. 平衡阴模配置如图4.4～图4.5所示，是流道均衡运行，全部的浇口需要同时到位。

但是此时流道相对性太长，是一个不足之处。

图4.4 浇口平衡图4.5. 浇口平衡Ⅱ. 改变浇口很横截面积采用一般流道的情况下，改变各浇口的横截面积，进行均匀填充取得浇口平衡。

各浇口的横截面积可通过以下的公式得出。

其中，W:(g)流道通过聚合物的重量SG : (mm2)浇口横截面积: (mm)到浇口位置的流道长度: (mm)浇口面的长度K: 根据聚合物的性质，模具等对应的常熟问题案例如同下图所示的流道。
