铸造铝合金车轮水冷模具的研究

Study on Water-Cooling Die for Aluminum Alloy Wheel Casting

为了增强铸造铝合金车轮模具的冷却强度,通过调整模具冷却结构,将冷却介质由压缩空气改为水,并借助模拟分析软件对铸造工艺进行改善研究。结果表明:水冷模具的冷却强度明显优于风冷模具,可以加快车轮铸件的凝固速率;使用水冷模具铸造车轮铸件可以提高生产效率,增幅达25%;生产的铝合金车轮微观组织更加致密,性能强度更加卓越。

In order to enhance the cooling strength of the cast aluminum alloy wheel die,the cooling medium was changed from compressed air to water by adjusting the die cooling structure,and the casting process was improved by means of simulation analysis software.The results show that the cooling strength of watercooling die is better than that of air-cooling die,and the solidification rate of wheel castings can be enhanced;the use of water-cooling die can improve the production efficiency of wheel castings by 25%;the aluminum alloy wheel produced by the water-cooling die has more compact microstructure and excellent strength.
