Abstract

The invention discloses an optimization design method for a die-casting machine, provides an optimization design method for a die-clamping mechanism of a horizontal die-casting machine. The optimization design method can be used for carrying out system analysis and optimization on the die-clamping mechanism of the die-casting machine according to the kinematics and elastomer dynamics system design principle, so that the initial starting speed and the overall weight and volume of the die-casting machine are reduced, the design difficulty of the die-clamping mechanism is lowered, and the die clamping performance of the die-casting machine is improved. The optimization design method solves the technical problems that the die-casting machine cannot run stably and efficiently by adjusting the parameters of the mechanism, and the die-clamping performance of the die-casting machine cannot be coordinated and optimized on the aspects of kinetic characteristics, force magnification ratios, deformation, rigidity and the like in the prior art. The optimization design method has the advantages that the multiple optimization of kinematics analysis and elastomer dynamics analysis is taken as a target, a relation between the length and the angle of the mechanism is studied from the point of system engineering, and an internal relation and a change rule between the system rigidities of the elbow-bar die-clamping mechanism are showed.
