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.
