Document Type and Number:
WIPO Patent Application WO/2019/003766
Kind Code:
A1
Abstract:
A method for manufacturing a press molded product is provided with a step for forming a plurality of angled parts (31G) in a part (31) to be pressed in a member (30) to be pressed, a step for disposing the member (30) to be pressed between a first mold (10) and a second mold (20), and a step for press molding the part (31) to be pressed such that the height of the part (31) to be pressed becomes smaller. In the step for press molding, a pair of first curved parts (31A) curved convexly toward the second mold (20) is formed in the part (31) to be pressed by the angled parts (31G). While holding the pair of first curved parts (31A) by a pair of holding parts (20B), a second curved part (31B) curved convexly toward the first mold (10) from a position between the pair of first curved parts (31A) is formed in the part (31) to be pressed by the angled parts (31G), and the second curved part (31B) is deformed by press.
