PURPOSE:To prevent the reduction in forging capacity and to enable good forging operation by piercing a through hole communicating to a cylinder room on a lower metal die and by arranging with inserting an ejector pin connected with a piston into the through hole. CONSTITUTION:When forged goods are formed with the completion of the forging work having the prescribed cycles, the air pressure is supplied via a passage 56 to cylinder rooms 50 which are arranged in plural units at the prescribed position of a lower metal die 24. An ejectering pin 58 connecting to a piston 52 is projected upwards from the surface of the lower metal die 24 with the function of the thrusting force of the cylinder room 50 to each piston 52. By ascending the ejectering pin 58 with the thrusting force synchronously and simultaneously, a forged goods is taken out simply with pushing up the forged goods from forming dies via a burr 48.
