Document Type and Number:
Japanese Patent JP7175077
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a mold for plastic working, which can mold a concave structure having a convex part or a concave part in the inside thereof and a complicated fine structure with high accuracy.SOLUTION: A mold for plastic working is a mold for molding a group of concave structures 4 provided with a concave part or a convex part in a target 3 to be processed. The mold for plastic working is provided with a group of molded convex parts 2 for molding a concave structure 4 on a top surface of a substrate 1 made of metal. The molding concave part 2 is formed into a multistage by laminating a plurality of metal layers. On a top surface of the substrate 1, a molding area 11 provided with a group of molding convex parts 2 is formed. In a state surrounding the molding area 11, a dummy area 13 is formed. In the dummy area 13, a group of dummy molding convex parts 15 having the same structure as the molding convex part 2 is formed.SELECTED DRAWING: Figure 1
