PURPOSE: A cam pierce device for a press mold is provided to prevent a punch of the cam pierce device and a processing product from being damaged by preventing the processing product from discharging in a state in which a slider is not completed. CONSTITUTION: A cam pierce device(1) for a press mold comprises a casing(110), a cam slide(120), and a cam driver(130). A compulsory restoration member is inserted into one side of the casing. The compulsory restoration member compulsively restores the cam slide to the rear if the cam slide is directly transferred to the front side by the cam driver. An approaching sensor(200) is installed to the rear end of the direct transfer direction of the cam slide and transmits a signal by sensing the cam slide transferred to the rear.
