PROBLEM TO BE SOLVED: To provide a press die which is inexpensively obtained with a simple structure using a cam installed in the die, and is provided with a cam type material feed mechanism to automatically send out a material for processing a work piece, and a material after processing by using a general-purpose press. SOLUTION: The cam type material feed mechanism comprises: a moving side cam 3 which has a cam surface 5 on the rear surface, a vertical surface 6 formed at a side in a feed direction, and is fixed to the rear surface of a movable die set 1; a fixed block 9 which has a pin 14 movable up and down and fixed to the upper surface of a fixed die set 2; a link plate 11; and an energizing means 12 interposed between the slide block 10 and a fixed block 9. A fixed side cam 4 having a cam surface 7 and a vertical surface 8 formed at a side in a reverse feed direction is fixed to one end of the link plate 11. A slide block 10 which has a pin 13 movable up and down and is arranged on the fixed die set 2 is fixed to the other end of the link plate 11. The link plate 11 is installed on the fixed die set 2.
