PURPOSE: A device for bending a blank material of a press mold is provided to carry out bending molding of a blank material under a stable molding condition, thereby preventing safety accidents in advance and damage of the blank material. CONSTITUTION: A device for bending a blank material of a press mold includes a movable element (34) slidably mounted at a side of a top surface of a lower die (31) of a lower mold and formed with a depressed part (34a) at a surface, a vertical bar (42) inserted in the depressed part of the movable elements at both ends to be protruded on the top surface of the lower die and penetratingly formed with a guiding elongated hole (42a), an internal element (43) slidably inserted in the guiding elongated hole of the vertical bar to be fixed at a side by the movable element, a lower cam (44) integrally protruded on a top surface of the internal element and formed with a closely contacting part (44a) of a predetermined inclination angle at a side, an external element (46) formed with movable indent groove (45) to be slidably inserted by the lower cam and the internal element and fixed to the lower die, and an upper cam formed with an inclination part of the same inclination angle with the closely contacting part of the lower cam and mounted in a slider of an upper mold to be vertically-movable for sliding the lower cam.
