DESIGN PARAMETER DETERMINATION METHOD OF INJECTION MOULDING OF RESIN, MANUFACTURING METHOD OF INJECTION MOLDING, AND DESIGN PARAMETER DETERMINATION PROGRAM OF INJECTION MOULDING OF RESIN

摘要

PROBLEM TO BE SOLVED: To generate weld at an appropriate position even if a shape of an injection molding is complex and complicated or like.;SOLUTION: The design parameter determination method includes: a shape model generating step (S01) that generates a shape model of an injection molding; a specific region information input step (S02) that inputs the information of a specific region in which the occurrence of weld is controlled in an injection molding; a filling time calculating step (S03) in which the filling time of the resin at each position when a resin is flowed from a specific region in the shape model is calculated; design parameter determination steps (S04-S09) in which a numerical analysis method acquires an inflow state of a resin to a shape model, and the design parameter is determined by an optimization method that uses a weighting evaluation function for the occurrence of weld of each position in a shape model based on the filling time; and a design parameter output step (S10) that outputs the design parameter.;COPYRIGHT: (C)2013,JPO&INPIT
