置の熱間型抜装置。 A mold is composed of a cylindrical die arranged so that the center axis line is along the vertical direction, and an upper punch and a lower punch arranged at the upper and lower parts of the hollow part of the die, respectively. It is attached to a hot press device that presses the sample filled between the punch and the lower punch and heats it to sinter it, and the die is supported or pushed up by a hydraulic cylinder driven by a hydraulic pump, thereby removing the die. In the hot die-cutting apparatus, an accumulator is provided in the hydraulic circuit for operating the hydraulic cylinder to accumulate pressure when the hydraulic pump is operated, and the hydraulic pump is not operated while the hydraulic cylinder is operating. 1. A hot die cutting device for a hot press device, characterized in that when stopped, the accumulator operates a hydraulic cylinder to support or push up a die.
