摘要

以某电器配件为研究对象

设计了一模两件的压铸浇注系统。以压射速度（A）、浇注温度（B）、模具温度（C）为影响因素

确定了3因素3水平的正交试验方案。结果表明

各因素对压铸件品质的影响能力为浇注温度>模具温度>压射速度。优化的压铸工艺是压射速度为0.7 m/s

浇注温度为620℃

模具温度为210℃。加工及检测验证结果表明

工艺优化后的压铸件孔隙率最低。

Abstract

Taking an electrical accessory as a object

one module-two cavities pouring process was designed. Injection velocity

pouring temperature

mold temperature as affecting factors

the orthogonal scheme was designed. The testing results show that the influential order of the factors on the quality of casting are presented as follows: pouring temperature

mold temperature

injection velocity

where the optimized processing parameters are 0. 7 m /s injection velocity

620 ℃ of pouring temperature and 210 ℃ of mold temperature

and the lowest shrinkage porosity can be obtained.
