摘要: 以某特种车辆支架零件为例,提出一种适用于大型复杂零件的挤压铸造成形工艺,设计了模具,并运用 ProCAST 软件进行了铸件流动场和温度场的数值模拟分析,验证了成形工艺参数. 最后运用 A356 铝合金进行了大型复杂支架的挤压铸造成形实验,试制铸件满足要求. 研究结果表明,所设计模具对大型复杂零件具有较好的成形能力,从而验证了该成形工艺对实现大型复杂零件挤压铸造成形的可行性和有效性.

Abstract: With the large and complex bracket part of a special vehicle as an example,a forming process method of
squeeze casting was proposed for large and complex parts,and a corresponding squeeze casting mold was designed.Then,the numerical simulations of the temperature and flow fields of castings were performed by using the software ProCAST,and the forming parameters were verified. Finally,a squeeze casting forming experiment of large and complex bracket parts was conducted on the A356 aluminum alloy material,and the castings meeting the requirements were obtained. The results show that the designed mold has a good performance in forming large and complex parts,which proves that the proposed squeeze casting forming process is feasible and effective.

Key words: Squeeze casting, Mold design, Large and complex parts, Forming process
