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。 In the large-area thin-walled aluminum alloy die-casting process, due to the characteristics of large-area thin-walled castings, small changes in process parameters and die structure is unreasonable, so that products such as poor forming, warpage, cold insulation and cracks Die-casting defects. Taking a typical large-area thin-walled die-castings as an example, the causes of die-casting defects were discussed through the analysis of process parameters and die structure, and corresponding countermeasures were put forward.
