CONSTITUTION:On the middle section of the rear surface of the base plate 1 of the upper die A, a flat part 2-1 is provided. The tapered parts 2-2 having descending slopes from the flat part 2-1 toward both ends are formed and trapezoid restricting members 3 is provided protrudingly on both sides of the upper die A. As for the lower die B, its constitution is similar. By this constitution, the dimensional accuracy of the products is improved.
