One of the pair of molds is equipped with a die having a hole for piercing and a peripheral protrusion for burring, and the other mold is equipped with a die for piercing. A punch that fits into the hole and a burring die that engages with the outer peripheral part for burring to perform burring are provided, and the burring die is attached to the other mold substantially through an elastic body. A mold device characterized in that it is configured to be pressed in the direction of the plate material supported by the one mold under the action of the elastic body. (2) In the apparatus set forth in claim 1 of the utility model registration claim, there is a device between one mold and the other mold that bends the end of the plate material as at least one of the molds is displaced. A mold device equipped with a mechanism for (3) In the device according to claim 2 of the utility model registration claim, the mechanism for bending the end of the plate includes a first pressing member attached to one mold side and having a first tapered surface, and the other. a second pressing member attached to the mold side and having a second tapered surface, the second pressing member being displaced toward the first pressing member side to form the first tapered surface and the second tapered surface, respectively. A mold device in which the end portion of the plate material is bent by a first pressing member by slidingly contacting the surface and displacing the direction of the pressing force.
