摘　　要：模板是注射机合模系统中的重要零件,但目前国内模板的设计还是以经验和类比为主。为此,通过采用先进的拓扑优化法,应用Ansys软件对注射机前模板进行结构优化。并研究了不同模型、不同约束条件下的拓扑优化结果,提出了在保证强度和刚度情况下前模板材料的最佳分布结构,该分析过程同样适用于动模板和后模板。拓扑优化方法为模板的创新性设计提供新的途径,能有效地解决工程设计中的实际问题。A platen is an important part of clamping unit in injection moulding machine, but its design mostly relies on experience and analogy at present. So through the introduction of advanced topological optimization, the structure of the front platen in injection moulding machine was optimized by the Ansys software. At the same time, using topological optimization results under different models and different restrictions, the best material distributing structure of the front platen was summed up. The analytical process of the moving platen and the rear platen was the same to that of the front platen. It is clear that topological optimization has practical guiding significance for the innovative design of the platen in injection moulding machine and solving the practical problems.
