摘　　要：设计并制造出盒体半固态压铸模,利用Flow-3D模拟软件对盒体半固态流变压铸充型及凝固过程进行了数值模拟,并进行了试验验证。结果表明,半固态压铸过程中,模具温度对半固态压铸影响较大。经过模拟优化的半固态压铸工艺参数:压射速度为1m/s,模具预热温度为260℃,浆料温度为590℃。The semi-solid die casting die for box shell was designed and manufactured. By using Flow-3D software, the filling and solidification process of semi-solid rheological die-casting was simulated, and verification experiment was conducted. The results show that the temperature of die has the obvious effects on semi-solid die casting process. The optimized parameters for semi-solid die casting were presented as follows： injection velocity of 1 m/s, pre-heating temperature of mould at 260 ℃ and slurry temperature of 590 ℃.
