MOLD FOR GLASS MOLDING AND METHOD FOR MOLDING GLASS MOLDED ARTICLE

WIPO Patent Application WO/2023/032414

A1

This mold 10 for glass molding comprises a molding surface 1 having a surface shape that corresponds to the shape of one side of a glass molded article, a heat-insulating portion 2 that is formed integrally with the molding surface 1 and includes at least one cavity 2a in a region of at least part of the reverse-surface side of the molding surface 1, and a base 3 for supporting the heat-insulating portion 2. Accordingly, the heat-insulating portion 2 formed integrally with the molding surface 1 is provided with heat insulation properties (decreases in thermal conductivity) due to including at least one cavity 2a in a region of at least part of the reverse-surface side of the molding surface 1. Thus, when pressing using the molding surface 1 to mold a glass molded article, the heat of the glass molded article dissipates via the molding surface 1 and cooling of the glass molded article can be suppressed, and the heat-insulating portion 2 can withstand the high molding pressure and high temperature of the glass molded article due to being formed integrally with the molding surface.
