【摘要】 介绍了从合模机构的强度和刚度要求出发进行注射成型机五孔斜排合模机构优化设计的方法。提出了等功效系数法的概念，并介绍了它在优化设计中的应用。由于综合处理强度和刚度，并简化处理目标函数，既达到了优化搜索方案的目的，又降低了编程难度，缩短了计算机运行时间，且能得到整个合模机构的结构尺寸。应用计算公式简洁、明了，具有明显的使用价值。更多还原

【Abstract】 An optimum design of clamping unit in injection molding machine was described taking the reqirements for the strength and rigidity of clamping unit into account.The equal efficiency coefficient concept was proposed and used in the optimum design.Inasmuch as the integrated process of strength and rigidity and the simplified process of object functions,the optimum alternative searching was realized,the difficulties in programming decreased,the working time of computer reduced,and the sizes of overall clamping unit elements were obtained.The formulas used in this work were simple,clear and practical.更多还原
