Document Type and Number:
Japanese Patent JP2002103407
Kind Code:
A
Abstract:
To provide a simple molded article designing method capable of preventing the generation of the molding defectiveness of a molded article including a part.
In the internal model of a cavity, assuming that the viscosity of a molten resin is uniform (S101), the volume of the molten resin and the space volume of a flow channel are compared (S102, S105) and, on the basis of the comparison result, part data and cavity data not leaving voids not only in the flow channel on the back surface of the part but also the flow channel between parts are determined (S108).
