Title:
PRESS-MOLDING METAL MOLD AND METHOD FOR MANUFACTURING PRESS-MOLDED ARTICLE
Document Type and Number:
Japanese Patent JP2019150865
Kind Code:
A
Abstract:
To provide a metal-molding metal mold capable of, when press-molding a plate-like member configured by welding a plurality of metal plates, suppressing damage of a metal mold generated by a weld bead part formed by the plate-like member, and a method for manufacturing a press-molded article.SOLUTION: A press-molding metal mold 13 of a plate-like member 12 configured by welding a first metal plate 120 and second metal plates 121, 122 has first-third partial metal molds 130-132 that press-mold parts excluding weld bead parts 123, 124 of the plate-like member 12. The first-third partial metal molds 130-132 are arranged, along the weld bead parts 123, 124 at positions facing the weld bead parts 123, 124 of the plate-like member 12, by providing gap parts 133, 134 with a predetermined width W1 wider than a width W0 of the weld bead parts 123, 124. An axle beam 10 has a press-molding process of press-molding by using the press-molding metal mold 13.SELECTED DRAWING: Figure 16
