摘要
通过Ansys有限元分析软件对铝合金车门内板挤压铸造过程建立有限元模型,并通过浇注温度、模具温度以及压机压下速度对熔体充型状态的影响进行研究,优化铝合金车门内板挤压铸造工艺。通过试验对模拟结果验证后表明：浇注温度在583～953 K范围内可以成功制造出较为完好的铝合金车门内板铸件。当浇注温度高于953 K时,压下速度较高会产生较多的气孔和氧化渣,对铸件顺序凝固不利;当充型结束后固相线温度区域变小,模具温度对铸件充型边缘影响较大。
The finite element model of squeeze casting process for aluminum alloy door inner panel was established through the ANSYS finite element analysis software. The effects of pouring temperature, mould temperature and press reduction speed on melt filling state were studied to optimize the squeeze casting process. The simulation results after verified by tests show that aluminum alloy door inner panel castings can be successfully produced when pouring temperature is between 583 K and 953 K. When pouring temperature is higher 953 K and reduction speed is higher, the porosity and slag oxidation will produce more adverse to the casting solidification sequence. After the filling finish, the solidus temperature area became smaller, the mold temperature have signification effect on casting＇s filling edge.
