摘　　要：对80T注塑机五支铰斜排双曲肘合模机构的运动特性和力学特性进行分析,确立以行程比和合模油缸推力放大倍数为优化目标,建立合模机构优化数学模型,确定参数化设计流程,并根据几何关系设立合理的约束参数,用MATLAB软件对合模机构进行优化设计.优化后,该机构行程比提高了31.91%,合模油缸推力放大倍数提高了0.46%,为降低五点斜排双曲肘合模机构的能耗,提高工作效率及注塑件的质量提供理论依据.This study analyses the movement characteristics and mechanical properties of the five-hinge diagonal row hyperbolic elbow clamping mechanism of the 80T injection molding machine, establishes the stroke-bore ratio and enlargement of the thrust of the clamping cylinder as the optimization goal, builds the optimization mathematical model of the clamping mechanism, determines the parametric design process, chooses reasonable constraint parameters according to geometry relationship, and uses the MATLAB software to optimize design for the clamping mechanism. After optimization, the stroke-bore ratio improves by 31.91% and the enlargement of the thrust of clamping cylinder by 0.46%. The improved design provides a theoretical basis for reducing the energy consumption of the five-point diagonal row hyperbolic elbow clamping mechanism and improving its working efficiency and the quality of injection molded parts.
