摘　　要：基于冷却系统的原始设计方案,分析预测了奔腾B50离合器壳体压铸模具表面及其内部节点达到热平衡时所需的循环周期数、平衡温度等热平衡参数;并对达到热平衡时的铸型表面及铸型平行等分截面上温度分布特点进行分析,详细评估冷却系统的合理性,获得了最优的冷却系统设计方案。实际铸件气密性检测和外观检测结果表明,优化后的冷却系统设计方案较为合理,可为类似大型、复杂离合器壳体高压铸造工艺方案的开发提供参考依据。Based on the original designs of the die cooling systems, an accurate thermal equilibrium analysis was carried out to predict the required cycles to die equilibrium and the equilibrium temperature at die surfaces and inside the dies for Besturn B50 clutch shell casting. The final optimized scheme of the cooling systems was determined, by analyzing the equilibrium temperature distribution at the die surfaces and different die sections. The results for air-leakage tests and the appearance observation of the final cast products show that the optimized cooling system design was reasonable and effective and could be applied to the design of similar products.
