To prevent the double punching and the like by detecting the discharge disability of moldings after pressing.

A suction pipe 11, which sucks and discharges a molding 1 being blown off is installed in front of an air pipe 8 which blows off the molding 1 being released from a die 2 forward and discharges it. The passing number of the molding 1 and the vertical movement number of a punch 3 are respectively counted by a detecting means 15 to detect the passing of the molding 1 which is mounted to an appropriate part of the suction pipe 11 and a detecting means 19 to detect the vertical movement of every to-and-fro movement of the punch 3. When the passing number of the molding 1 becomes smaller than the vertical movement number of the punch 3, the actuation of the press molding device is stopped.
