基于ProCAST吸阀壳体铸铝件铸造工艺设计

Casting Process Design of Aluminum Suction Valve Housing Based on ProCAST

以吸阀壳体铸件为研究对象,通过对铸件材质、形状、大小及结构特点进行详细分析,提出合理的铸造工艺设计方案。运用ProCAST数值模拟软件进行铸造工艺数值模拟,对模拟结果的充型过程、缺陷分布以及工艺改进性等方面进行分析。结果表明,采用平做立浇工艺、开放式底注式浇注系统,再添加冒口及冷铁,使铸件形成一个自下而上的顺序凝固,可消除铸件存在的缩松、缩孔缺陷,确保得到符合使用条件的合格铸件。

The suction valve housing casting process was designed through detailed analysis of casting material, shape, size and structural characteristics, and then the ProCAST software was used for numerical simulating of casting process, the filling process and defect distribution. The results show that when the horizontally molding and vertically pouring process and non-pressurized bottom pouring system are adopted, the addition of the risers and chill can ensure that the casting solidifies in a bottom-up order and the shrinkage hole and dispersed shrinkage defects in castings can be eliminated. Therefore, the qualified castings can be produced.
