PURPOSE:To facilitate the dismount of an upper die by composing the upper die having stipulated dimension by dividing it into a middle part and end part and forming the end part obliquely movably to the inner side. CONSTITUTION:An upper die is composed of a middle part 1 and end parts 2, 3 to form the tapered inclined faces 4, 5 whose length dimension of the lower part is reduced more than that of the upper part is formed on the middle part 1. On the end parts 2, 3 the inclined faces 6, 7 corresponding to the inclined faces 4, 5 are respectively formed, and the inclined faces 4, 6 and 5, 7 are slidably connected each other to the middle part 1 and end parts 2, 3 by a pin 8, an oblong hole 9, etc. In the case of performing bending and the wrinkle 12 formed on the back side of a product coming into the grooves 10, 11 of the upper die end part, the end parts 2, 3 are obliquely moved with the upper and lower relative movements of the middle part 1 and end parts 2, 3. The upper die is thus dismounted from a product easily.
