Abstract
A method of manufacturing a press mold for mass-producing a hot stamping cold trim includes bonding first and second steel bodies made of different materials to form a single body mold material, polishing a bottom surface and one edge surface of the mold material with processing margins, processing edge surfaces other than the one edge surface on which a bonding part is positioned, processing reference holes for guide pins and a reference surface, forming bolt holes penetrating through the reference surface and the bottom surface, processing a surface of the first steel body in a predetermined shape, heat-treating the mold material, and polishing the bottom surface and the one edge surface having the processing margins at desired accurate dimensions and wire-processing the one edge surface with the processing margin to configure a front end part having the desired accurate dimension.
