Abstract
A powder molding press, for compression-molding a raw powder between a pair of metal molds coupled to a pair of metal mold securing devices. At a preset spacing, the movement of the metal mold securing devices toward each other is electrically detected in order to cut off the driving means advancing the metal mold securing devices. In addition, the movement of the metal mold securing device is mechanically stopped by means of stoppers, with the result that the final position of the metal molds can be precisely regulated.
