て知られている。2. Description of the Related Art In order to reduce the man-hours and time required for mold production of press dies and the like, a mold itself is produced by an assembly of rod-shaped members, and an arbitrary mold surface shape is created on one end surface of the assembly. The technology is disclosed in, for example, JP-A-56-36343,
