摘　　要：为了设计桌面型微注塑机的锁模机构,在对注塑机锁模肘杆机构的运动学特性和力学特性进行理论分析的基础上,确定了最佳的肘杆几何参数,对肘杆机构进行了运动学仿真分析和静力学分析。结果表明,设计的桌面型微注塑机的肘杆锁模机构能够满足慢-快-慢的理想速度特性,并且在能够提供100 kN锁模力的前提下,满足刚度和强度的要求。In order to design a clamping mechanism of desktop model micro-injection molding machine, based on the theoretical analysis for the kinematics characteristics and mechanical properties of the elbow rod clamping mechanism for the injection molding machine, the optimal geometric parameters of the elbow rod were determined, and kinematics simulation and static analysis for the elbow rod were carried out. The results showed that the elbow rod clamping mechanism of desktop model micro-injection molding machine met the ideal slow-fast-slow speed characteristics, and it could meet the requirements of rigidity and strength on the premise of being able to provide 100 kN clamping force.
