内循环二板式注塑机锁模油缸后端连接支撑结构的数值分析与优化

he four-cylinder interlocking internal circulation hydraulic system is suitable for small and medium-sized two-plate injection molding machines, and has great advantages in clamping precision and energy saving. However, since there are four clamping cylinders, and in order to meet the long cylinder length of the mold opening, the cylinder is unbalanced and the deformation and stress are large. Therefore, it is inevitable to increase the connection support structure at the rear end of the clamping cylinder. In order to optimize the uniformity and stability of the existing internal circulation two-plate injection molding machine clamping system, the numerical analysis and optimization of the rear-end connection support structure of the clamping cylinder are carried out. The different connection support structures are studied by numerical simulation technology. The effect of deformation and stress on the clamping system of the injection molding machine. The study determined the optimal structure of the n-type connection support structure.
