摘要

针对弯管接头压铸件结构进行分析

利用正交试验

模具预热温度为200℃

铝合金浇注温度为660℃。

Abstract

Based on the analysis of aluminum die-casting bended tube joint structure

die casting processing parameters were optimized by orthogonal test and numerical simulation.According to numerical simulation analysis of the casting process

the temperature field

filling flow condition

shrinkage position and shrinkage porosity can be presented.By orthogonal testing

the optimized process parameters are presented as follows:injection speed of 1.8m/s

mold preheating temperature of 200 ℃

pouring temperature of 660 ℃.
