| 摘 要： | 本研究指出轮辋缩松的原因分为两类:热缩松和冷缩松,两种类型缩松的改善措施也不尽相同。通过优化产品毛坯局部厚度、修改模具局部冷铁壁厚、局部位置添加保温材料、修改模具冷却布局及选择不同种类涂料的方式可有效改善产品轮辋缩松,但需要根据实际情况进行措施选择、搭配。

| Abstract: | This study points out that there are two reasons for rim shrinkage:shrinkage caused by high temperature and shrinkage caused by low temperature.The improvement measures of two kinds of shrinkage are different.By optimizing the local thickness of the blank,modifying the local thickness of the mold,adding insulation material in the local position of the mold,modifying the cooling layout of the mold and using different types of coating,we can effectively improve the rim shrinkage.However,we need to choose and match measures according to the actual situation. |
