The locating mold is formed in the center of a base plate(21). A material(20) is installed in the locating mold. The side clamping units are formed in the locating mold and restrict both surfaces of the material. The fixed frame is formed on the top of side clamping units through mounting frames(25) installed in both sides of the base frame. The upper clamping units are formed in both sides of the fixed frame and restrict the top surface of the material. The notching unit is formed in the center of the fixed frame and powers a notching mold.
