摘　　要：以某圆筒状铝合金铸件为例,研究了浇注系统设计及工艺参数优化方法。首先根据铸件结构特点和低压铸造原理,设计了包含中心直浇道和底部、顶部横浇道的浇注系统。然后采用正交试验设计,结合Procast软件模拟分析了不同保压时间、模具预热温度和铝液温度对铸件充型和凝固过程的影响,确定了最佳工艺参数:模具预热温度360℃,铝液温度700℃,保压时间280 s.最后,采用优化后的工艺参数进行试生产,获得了内部质量合格的铸件,验证了该方法的可行性。This paper takes a cylindrical aluminum alloy casting as an example to study the casting system design and process parameter optimization method.First of all,according to the structural characteristics of the casting and the principle of lowpressure casting,a casting system including a central straight casting channel and a horizontal casting channel at the bottom and top is designed.Then,the impact of different pressure retention time,mold preheating temperature and aluminum liquid tempera⁃ture on the filling and solidification process of casting was analyzed by using orthogonal test design and combined with Procast soft⁃ware simulation,and the best process parameters were determined:mold preheating temperature 360℃,aluminum liquid tempera⁃ture 700℃,and pressure retention time 280 s.Finally,the optimized process parameters were used for trial production,and the in⁃ternal quality qualified castings were obtained,and the feasibility of the method was verified.
