Abstract

According to the characteristics and requirements of all-electric five-point oblique toggle die casting machine

the mathematical models of toggle clamps were established.Cumulative function of normal distribution was used to construct the objective function.Expectations and the amount of fluctuation of the main performance parameters were determined

and the optimization constraint was set.Based on the method for solving constrained nonlinear optimization

the mold closing mechanism was optimized systematically.The results show that the force amplification ratio is enhanced greatly after optimization design

and the overall performance is more suitable for electric die casting machines.
