PROBLEM TO BE SOLVED: To provide an apparatus and method for hot press working of a metal plate, which can quickly produce a press working product having excellent strength and geometrical accuracy, and further to provide a method for manufacturing the apparatus for hot press working of the metal plate. SOLUTION: The apparatus for hot working of the metal plate is characterized in that in the apparatus for hot press working of the heated metal plate, a supply pipe 6 for supplying a cooling medium is provided inside a die, and further injection nozzles 4 are provided so as to go through from the forming surface of the die to the supply pipe. A discharge pipe of the cooling medium may be provided inside the die, and exhaust nozzles going through from the forming surface of the die to the discharge pipe may be provided, and further a cooling pipe may be provided. The method for hot working of the metal plate is characterized in that the working is carried out while injecting the cooling medium from injection nozzles into the clearance between the metal plate and the die. The cooling medium injected into the clearance between the metal plate and the die may be discharged from the injection nozzles and/or the exhaust nozzles. COPYRIGHT: (C)2005,JPO&NCIPI
