摘　　要：设计了铝合金半固态模锻标准拉伸试样模具,采用一模五件。选用典型锻造铝合金7075作为材料,用Deform软件进行模拟分析,分别进行流动充型试验,对比分析不同的充型结果。确定合理的坯料尺寸、放置方式及半固态温度为:60×120mm,垂直放置,580℃。选用7050合金进行实际半固态模锻成形,制备了拉伸试样零件,结果表明,本模具设计合理,充型流动模拟优化方法合理可靠。In the paper, moulds of semi - solid forging standard tensile samples of aluminum alloys are designed, and one set of mould can produce five samples once a time. Wrought aluminum alloy 7075 is used as typical material. The process is analyzed by Deform software. The result shows that the design of the mould is reasonable and the optimization process of simulating the filling process is reasonable and reliable as well.
