Study on Low Pressure Die Casting Process of A356 Aluminum Alloy Cylinder

利用ViewCast软件对低压金属型铝合金A356铸造过程进行了计算机模拟,预测了产生缩孔、缩松缺陷的位置。通过计算机模拟以及对铸件表面缺陷进行分析,提出了生产工艺方案,铸造出了满足质量要求的铸件。所铸的铸件表面质量好、无缩松等铸造缺陷。这为铝合金金属型低压铸造模具设计及工艺研究提供了有价值的参考。

The low pressure die casting process of A356 aluminum alloy was simulated by ViewCast software, and the location of the shrinkage defects was forecasted. The producing process was proposed by computer simulating and analyzing the surface defect of the aluminum alloy castings. Regular castings were produced, the surface quality was obviously improved and no defects such as shrinkage were found. It provides the valuable reference for the research of low pressure die casting process and mold design of aluminum alloy permanent mold.
