Proposed is a method for press-molding an embossed steel plate, the method being able to cool even an embossed steel plate under conditions adequate for quenching. After a plate body 10 with convex portions 2 formed thereon is placed between upper pressing die 3 and lower pressing die 4 and the dies are closed, a first circulation pump is run to circulate cooling water within the upper pressing die 3, through a cooling medium passage 5A †’ a communication channel 7A †’ a cavity S †’ a communication channel 7B †’ a cooling medium passage 5B †’ a cooling medium passage 5C †’ a communication channel 7C †’ the cavity S †’ a communication channel 7D †’ a cooling medium passage 5D †’ a cooling medium passage 5E †’ a communication channel 7E †’ the cavity S †’ a communication channel 7F †’ a cooling medium passage 5F †’ the cooling medium passage 5A. Further, a second circulation pump is run to circulate cooling water within the lower pressing die 4, through a cooling medium passage 6A †’ a communication channel 8A †’ the cavity S †’ a communication channel 8B †’ cooling medium passage 6B †’ a cooling medium passage 6C †’ a communication channel 8C †’ the cavity S †’ a communication channel 8D †’ a cooling medium passage 6D †’ a cooling medium passage 6E †’ a communication channel 8E †’ the cavity S †’ a communication channel 8F †’ a cooling medium passage 6F †’ the cooling medium passage 6A. |
