Title:
METHOD FOR SELECTING MOLD SHAPE
Document Type and Number:
WIPO Patent Application WO/2024/057840
Kind Code:
A1
Abstract:
This mold shape selection method, for selecting a shape for a mold in a pressing machine, comprises a parameter creation step for creating a parameter group that includes a plurality of parameters, a simulation step for simulating a plate shape on the basis of the parameter group, and a selection step for selecting a mold shape on the basis of a plurality of plate shapes obtained by performing the simulation step a plurality of times, the mold being provided with a first die that includes a first molding surface and a second die that includes a second molding surface, the first molding surface being formed with first through fourth curvature radii as dimensions, the second molding surface being butted against the first molding surface during pressing, and being formed having a width that is a multiple of 1/α of the width of the first molding surface, and the plurality of parameter groups including the first through fourth curvature radii and a ratio α.
