Abstract

本实用新型公开了一种减少轮辐根部缩松的车轮模具顶模。车轮毛坯轮辐根部的模具顶模设置导热棒,导热棒用紫铜制作。紫铜的导热率为407w/mk,而车轮模具顶模的材料碳素钢的导热率为48w/mk,紫铜的导热率是碳素钢的8.48倍。紫铜部位的车轮轮辐根部的热量可内紫铜快速传导,防止轮辐根部的缩松产生。

Description

一种减少轮辐根部缩松的车轮模具顶模
技术领域
本实用新型涉及一种模具,具体地说涉及一种车轮模具顶模。
背景技术
现有技术的车轮模具顶模为一整体,在车轮毛坯筋部热节处容易缩松。
实用新型内容
本实用新型的目的是提供一种解决车轮毛坯轮辐根部缩松的车轮模具顶模。
本实用新型一种减少轮辐根部缩松的车轮模具顶模的技术方案为:车轮毛坯轮辐根部的模具顶模设置导热棒,导热棒用紫铜制作。
紫铜的导热率为407w/mk,而车轮模具顶模的材料碳素钢的导热率为48w/mk,紫铜的导热率是碳素钢的8.48倍。紫铜部位的车轮轮辐根部的热量可内紫铜快速传导,防止轮辐根部的缩松产生。
附图说明
图1是本实用新型一种减少轮辐根部缩松的车轮模具顶模局部示意图。
图中:1-导热棒。
具体实施方式
如图1所示,本实用新型一种减少轮辐根部缩松的车轮模具顶模由顶模主体和导热棒组成,导热棒设置在车轮轮辐根部,导热棒用紫铜制成。
