摘　　要：针对铸件结构基于工程经验设计了压铸件的浇排系统和初始压铸工艺参数,采用有限元软件ProCAST进行压铸过程的充型凝固耦合模拟仿真,并采用Design-expert,基于BoxBeheken的响应面法(RSM)建立了以模具温度、铝液温度和快压速度为因素,以缺陷体积为目标响应的试验,最终得到较优的试验方案。利用试验优化后的工艺参数进行生产试验。结果表明,采用优化方案生产出的铸件表面质量良好,内部易产生缺陷位置的孔隙度为1%,整体符合质量要求。Firstly,based on engineering experience,the pouring system and initial die-casting process parameters for the casting structure were designed.Subsequently,the finite element software ProCAST was used to simulate the coupling of mold filling and solidification during the die casting process.Design expert was used to establish an experiment based on Box Beheken′s Response Surface Method(RSM),with mold temperature,aluminum liquid temperature,and fast pressing speed as research factors and defect volume as the target response.The optimal experimental plan was ultimately obtained.Then,production experiments were conducted using the optimized process parameters.The results showed that the surface quality of the castings produced using the optimized plan was good,and the porosity of the internal defect prone positions was 1%,which overall met the quality requirements.
