摘要：

双曲肘合模机构是热室压铸机的重要组成部分，决定着压铸成形的品质和生产效率。为提高双曲肘合模机构设计的合理性，在满足各工况要求的情况下，增强合模机构的结构紧凑性，从而提高生产效率，降低其生产成本。为了避免原有的物理样机进行多目标优化带来的繁杂问题，应用ADAMS_View多体动力学分析优化软件，对合模机构开合模过程进行分析，得到动模板和十字架的位移和速度曲线，并根据各参数对优化目标的敏感值进行了优化调整。结果表明，通过运用ADAMS软件优化后的双曲肘合模机构的动模板速度比优化前有所提高，提高了模具生产效率，且在满足各工况要求的条件下，其质量有所减小，制造成本更低。

Double elbow dieclosing mechanism is an important part of hot chamber diecasting machine，which determines the quality and productivity of die casting. In order to improve the rationality of the design of double elbow dieclosing mechanism and meet the requirements of various working conditions, the structure compactness of the dieclosing mechanism was improved to increase production efficiency and reduce production cost. In order to avoid the complicated problems caused by the multiobjective optimization on the original physical prototype, the opening and closing processes of dieclosing mechanism were analyzed by multibody dynamic analysis and optimization software ADAMS_View, and the displacement and velocity curves of the moving templace and the cross were obtained. Furthermore, the sensitive values of parmeters to the optimization objective were optimized. The results show that the speed of moving template for double elbow dieclosing mechanism optimized by software ADAMS is higher than that before optimization, so as to improve productivity of die. Under the condition of satisfying the requirements of various working conditions, the weight of double elbow dieclosing mechanism is reduced, and the manufacturing cost is lower
