Optimum Design of Mass Distribution of the Injection Molding Pantograph Mechanism with Constant Output Link Orientation
In this paper, an optimum design of an injection molding pantograph mechanism is discussed. This mechanism will be used to the miniature surface mount system in one room factory. First, a reduction of force acting at hinge caused by the movement of the mechanism is discussed. And the injection molding pantograph mechanism is synthesized based on the result of a numeric calculation of the algorithm. Moreover, the force acting at hinge of this mechanism is analyzed, and the algorithm that reduces force acting at hinge by changing the shape and dimension of links considering the influence of the movement of the mechanism is proposed. In addition, the shape and dimension of links to which force acting at hinge of this mechanism is reduced from the result of a numeric calculation of this algorithm is designed.
