摘要
通过对一种差压铸造铝合金转向节Hub安装孔安装位置缩松的分析,得出了导致铸件缩松的原因主要是由于Hub安装孔对应模具位置处冷却强度不足。通过优化该位置模具水冷接头结构,增大热传导率,提高冷却强度,缩松问题得到解决。
Through analyzing a kind of counter-pressure casting aluminum alloy knuckle flange shrinkage located in Hub assemble hole, it was concluded that the reasons of shrinkage were mainly contributed to insufficient cooling intensity in Hub assemble hole corresponding to mold. After modifying mold water cooling connection structure, and increasing thermal conductivity and improving the cooling efficiency, therefore the problem of shrinkage was solved.
