Claims

[Scope of utility model registration request]

A metal material is sandwiched between a first mold provided with an ejection mold that moves forward and backward into the mold, and a second mold that is butted against the first mold, and deformed under pressure. A die structure of a forging press device for forming a forged product of a predetermined shape from a forging die, the die structure including a floating means for floating the first die and retracting the ejection die from the first die, The material is positioned in the recess created by the retraction of the ejector mold and deformed under pressure, and the first mold and the second mold are moved together before the ejection mold completes its intrusion operation. A mold structure for a forging press device, characterized in that the mold structure is configured to form a closed mold in which the material is hermetically housed in contact with each other.
