摘　　要：运用ANSYS软件对塑料注塑机固定模板结构进行拓扑优化。将不同体积约束下拓扑优化的结果进行了研究对比,获得了模板在强度和刚度不变乃至增加的前提下材料的最优分布结构。按照分析结果所作的合理设计不仅可以节省材料,还可以通过减小模板最大挠度来提高注塑产品质量。The fixed platen structure of the injection molding machine was optimized by topological optimization method using the ANSYS software. The topological optimization results of different volume restrictions were compared. The best material distributing struc- ture of the platen with nondecreasing strength and stiffness was obtained. The optimal de- sign according to the analyse result not only reduces the material using, but also improves the quality of injection products by reducing the most deflection of platen.
