在大面积薄壁铝合金件压铸过程中

由于铸件大面积薄壁的特点

工艺参数的较小变化和模具结构的不合理

使产品产生诸如成形不良、翘曲变形、冷隔和裂纹等压铸缺陷。以一个典型的大面积薄壁压铸件为例

通过对工艺参数和模具结构的分析

探讨了压铸件缺陷产生的原因

并提出了相应的对策。

During die casting large area and thin-walled aluminum alloy

some defects

such as cob webbing

warpage

cold shut and crack

occur in the die castings as a result of large area and thin wall

small change of parameters as well as unreasonable mold structure.Takes a large area and thin wall die casting as a typical example

through analyzing die casting parameters and mold structure

defects reason was described

and corresponding countermeasures were presented.
