摘　　要：针对铝合金轮毂铸件整体质量不高的问题,采用ProCAST软件分析了低压铸造铝合金轮毂的充型和凝固过程的温度场分布规律。根据数值模拟结果,提出在模具上多处加设冷却管道的工艺方法。结果表明,该方法提高了轮毂的冷却速度,获得铸件的质量较好,提高了生产效率。To solve the problem of casting quality,the ProCAST software was adopted to analyze the temperature field distribution during filling and solidification process.Based on the simulated results,the methods of setting up cooling pipes on the mold was put forward.The results show that the method can increase the cooling speed of wheel to obtain the satisfied casting quality and improve production efficiency.
