Optimization design of elbow-bar mechanism in injection molding machine based on genetic algorithm

By taking the original errors as stochastic variables,the reliability of the elbow-bar mechanism of automatic die cutting machine was analyzed and calculated in three instances,namely only in the presence of the error of bar length,only in the presence of joint-gaps of hinge or in the presence of the both of them.

In this article, elbow-bar framework of the Die-Cutting system of Blocking Die-Cutter was analyzed with numerical method, and the author also designed an experiment to verify the theoratical analysis.

Motion analysis and optimum design of the dual-elbow-bar mechanism of the die-cutting machine;

Motion analysis of the dual-elbow-bar mechanism of the die-cutting machine based on the loop method;

The simulating motion curve of the dual-elbow-bar mechanism was drawn and its motion characteristics were analyzed.

The parameters of this crank-elbow bars mechanism are given and the distinguishing features and performances of this opening-closing die mechanism are discussed.

Through analyzing and researching in toggle clamp for manifold models (including back lever model, height of the crosshead, size of middle lever, locking final corner, clamping thrust corner and ratio of the levers' length), the writer is discussing for better model of presented above toggle clamp in the paper.
