Abstract:
Provided is a die-pressing die mold that is capable of suppressing incursion of garbage G into a lower free ball bearing 49 and sufficiently preventing the garbage G from damaging the back surface of a workpiece W. A die hole 39 is formed in the center of the upper surface of a die body 37 and a discharge hole 41 is formed in the center of the die body 37. The lower free ball bearing 49 is provided to the inside of the die hole 39. A peripheral groove 59 is formed on the outer peripheral surface of the die body 37, a plurality of supply passages 65 are formed on the outer peripheral side inside the die body 37. The pressure inside the discharge hole 41 becomes negative when high-pressure air is supplied to the supply passages 65.
