PURPOSE:To discharge easily the gas stagnating in a die device by passing pressurized air to a discharged passage formed by working a part of a die engaging surface and discharging the air by the suction effect generated in the discharge passage. CONSTITUTION:An air hose 11 for conducting pressurized air provided in the upper part of a die 7 communicates with an air feed passage 12 provided to the body of a die 7. The other end of the passage 12 communicates with a discharge passage 13 formed by working a part of the engaging face. The pressurized air discharged from the passage 12 to the passage 13 flows in the form of a jet toward the outside of the die device. The jet introduces consequently the gas in the vent passage near the passage 13 and the gas is moved together with the jet toward the outside of the die device, by which a suction effect is generated in the passage 13. |
