Abstract
PURPOSE: To easily fetch a forged port having no draft on the external face and to remarkably shorten an external face finishing stage thereafter by cooling the external face of a forged part by spraying the fluid for cooling from the jet hole arranged on the inner wall face of a female die for hot forging.
CONSTITUTION: A fitting 9 with a jet hole 8 is provided in an air passage 7 at optimum intervals on the inner wall face of the female die 1 for hot forging. The formed part 3 subjected to hot forging by this female die 1 and a male die 2 is shrunk by cooling by the air blown from a jet hole 6 and taken off easily by the female die 1 even without any draft. Since there is no unnecessary draft on the formed part 3 an external shape forming is not necessitated and even in the case of executing the finishing a finishing allowance is minimized and the man-hour thereafter is drastically reduced.
