摘　　要：小型塑壳断路器模具设计面临着结构复杂、冷却不均和加工精度难以保障等问题。文章通过计算机辅助诊断(Computer Aided Diagnosis,CAD)技术优化模具设计,结合热场分析和结构优化方法,提高模具的强度、刚性和冷却效率。在模具设计过程中,CAD的拓扑优化帮助去除冗余部分,提升模具的稳定性,动态仿真则确保了模具在实际工况下的可靠性。通过热场分析,优化了冷却系统,确保模具的均匀散热,避免了成型缺陷。实验结果表明,优化后的模具设计提高了生产效率和产品质量,减少了试模次数和制造成本。The design of moulds for miniature plastic-encased circuit breakers is confronted with issues such as complex structure,uneven cooling and difficulty in ensuring machining accuracy.The paper optimizes the mould design by using CAD technology,combined with thermal field analysis and structural optimization methods,to enhance the strength,rigidity and cooling efficiency of the mould.During the mould design process,topological optimization of CAD helps to remove redundant parts and improve the stability of the mould,while dynamic simulation ensures the reliability of the mould under actual working conditions.Through thermal field analysis,the cooling system is optimized to ensure even heat dissipation of the mould and avoid forming defects.Experimental results show that the optimized mould design improves production efficiency and product quality,reduces the number of trial moulds and manufacturing costs.
