HOT-PRESS MOLDING APPARATUS, AUTOMOTIVE BODY COMPONENT, HOT-PRESS MOLDING METHOD, AND PRODUCTION METHOD FOR AUTOMOTIVE BODY COMPONENT

WIPO Patent Application WO/2022/145139

A1

This hot-press molding apparatus comprises: an upper mold (14) which has a molding surface for molding a to-be-molded portion (4) of a metal sheet material (2) and which also has an edge (32a) that serves as a punch (32); a lower mold (13) which has a molding surface (21) for holding and molding the to-be-molded portion in cooperation with the upper mold; and a die (16) that is configured to separate, in cooperation with the edge of the upper mold, a trimming portion (3) located outside of a molded portion in the metal sheet material, which results from molding of the to-be-molded portion by the upper and lower molds, from the molded portion. The upper mold has an outer lateral surface (14a) that is formed so as to extend toward the cutting direction of the punch, and that defines a cooling inhibiting space (62) in which the trimming portion is exposed at the lateral side of the upper mold so as to inhibit cooling of the trimming portion.　It is possible to provide a hot-press molding apparatus that is capable of preventing generation of delayed fracture in a molded product.
