Abstract
A hot-press molding apparatus includes an upper mold () having a molding surface for molding a to-be-molded portion () of a metal sheet material () and a blade () serving as a punch (), a lower mold () having a molding surface () for molding the to-be-molded portion by sandwiching it in cooperation with the upper mold, and a die () configured to separate, from the to-be-molded portion, a trimming portion () positioned outside the to-be-molded portion in the metal sheet material in which the to-be-molded portion is molded by the upper mold and the lower mold, in cooperation with the blade of the upper mold. An outer side surface () of the upper mold is so formed as to extend in the cutting direction of the punch, and defines, on the side of the upper mold, a cooling suppression space () to which the trimming portion is exposed and which suppresses cooling of the trimming portion. A hot-press molding apparatus capable of preventing the occurrence of delayed fracture in a molded product is provided.
