Abstract
PURPOSE:To easily obtain a forming mold of carbide metallic material, further facilitate its work and perform high accurate machining of a V-groove, by manufacturing a pressure forging mold in which corner parts of two square pillars are chamfered and then the V-groove is formed by combining these pillars. CONSTITUTION:Prescribed corner sides of two square pillars 4, 5 are chamfered respectively to desired shape and dimensions to form sloped surfaces a, b, further these sloped surfaces a, b are mutually combined to form a pressure forging V-groove for a triangularly sewing needle or the like.
