【Abstract】 The relationship formula of the displacement and velocity between the moving moulding plate and the motor of electric injection molding machine was derived according to principle of connecting rod kinematics and the curves of displacement and velocity were fit by using Metlab software.Then,the change of displacement and velocity of moving moulding plate could be monitored effectively through these curves,and it served users as the theory basis for setting the mould protection function.The locking force was also tested by using the affixable resistance strain gage method and the relationship formula of the initial position of moving moulding plate and the locking force was obtained,the stability of locking force in injection process was insured.更多还原
