Optimization Design of the Toggle Clamping System for a Plastic Injection Molding Machine

摘要

The main purpose of this work is to design the toggle system for an injection molding machine (IMM). Its stroke, clamping force amplitude, and close mold speed of the system are taken as the three objective functions by using optimization method and 3D design simulation software. From our numerical results the optimal design are really better than the original design: (1)The relation stroke has been increased. (2)The clamping force amplitude has been improved. (3)The starting velocity of moving platen in the initial point is reduced, and reaches a higher velocity in the middle stage.
