Claims

[Scope of utility model registration request]

This is a plain mold for producing a product having an arcuate corner on the side wall by drawing a press work, and includes a lower mold having a concave mold surface and a convex mold surface corresponding to the concave mold surface of the lower mold. The upper mold has been formed, and a blank holder presses the outer peripheral part of the press work on the outer peripheral upper surface of the lower mold from above, and the concave mold surface of the lower mold has a product recess corresponding to a product shape having corners. and an outer peripheral recess located above the product recess and forming a step between the lower mold outer peripheral upper surface and the product recess along the outer periphery of the product recess, and corresponding to the corner of the product. The side wall of the outer circumferential recess is a plane parallel to the tangent to the corner, and the convex die surface of the upper die is also formed with a plane corresponding to the lower die plane.
