Slope-pressing and convex hull-raising composite die

The utility model relates to an inclined pressing and convex hull forming composite die. The inclined pressing and convex hull forming composite die comprises an inclined pressing punch, a convex punch, a steel backing positioning pin and a lower material ejector. The inclined pressing punch is fixed to the upper die, and a working face used for punching an inclined face is formed on the bottom side of the inclined pressing punch. The raising punch is fixed on the lower die and is used for punching a convex hull on the steel backing of the brake pad, and the upper die is provided with a raising channel which is matched with the raising punch and is used for accommodating the raising punch; the steel backing positioning pin is fixed to the lower die and used for being connected with the brake pad steel backing in a clamped mode in the horizontal direction. The lower material ejector is fixed to the lower die and used for pushing and jacking the brake pad steel backing to the position above the protruding punch
