摘　　要：以某新能源汽车铝合金电池端板为研究对象,基于正交试验设计以及信噪比分析法探究低压铸造过程中金属液的浇注温度、模具预热温度以及充型时间3个工艺参数对铸件成型质量的影响,以缩松缩孔体积值、凝固时间和二次枝晶间距大小为评价指标,探究出一套标准化的工艺设计参数,为新能源汽车铝合金电池端板低压铸造成型工艺研究与实际生产提供重要参考。研究结果显示:浇注温度690℃,模具预热温度330℃,充型时间8 s时铸件无缩松缩孔缺陷,二次枝晶间距最小,凝固时间最短。Based on an orthogonal experimental design and signal-to-noise ratio analysis,the effects of three process parameters-casting temperature,mold preheating temperature and mold filling time-on casting quality in lowpressure casting were investigated,and a set of standardized process design parameters using shrinkage rate and shrinkage pore volume,solidification time and secondary dendrite interval as evaluation indicators were explored.A set of standardized process design parameters was investigated as an important reference for the study and practical application of a low-pressure casting process for aluminum alloy battery end plates for new energy vehicles.The results showed that the casting temperature of 690 ℃,the die preheating temperature of 330 ℃ and the filling time of 8s resulted in no shrinkage or shrinkage of the castings,the smallest secondary dendrite spacing and the shortest solidification time.
