摘要
合模机构是注射机非常重要的部件,它不仅关系到注塑产品的质量,而且影响了注射机的效率及功耗。本文主要对常用双曲肘合模机构的结构组成及工作原理作了分析介绍,然后对双曲肘合模机构建立了数学模型,通过分析计算得到了动模板和十字头的速度、加速度、行程等的理论方程,最后利用ADAMS软件对合模过程作了运动学分析,得到了动模板的行程、速度、加速度仿真曲线,证明了设计的合理性,为双曲肘合模机构进一步的优化设计提供了理论参考。
Clamping mechanism is a very important part of injection molding machine.It not only affects the quality of injection products but also affects the efficiency and power consumption of injection molding machine.In this paper,the structure composition and working principle of common double-toggle clamping mechanism were introduced.Then the mathematical model of double-toggle clamping mechanism was established,and the theoretical equations of velocity,acceleration and travel of moving template and crosshead were obtained through analysis and calculation.At last,the kinematics analysis of the mold closing process was made by ADAMS software,and the simulation curves of travel,velocity and acceleration of the moving template were obtained,which proved the rationality of the design.It provided a theoretical reference for further optimization design of double-toggle clamping mechanism.
