易に行い得て、実用上有利である。As explained in detail above, according to the present invention, the middle plate cut by the two slits of another metal substrate is removed,
cutting into a desired shape with a cutting device to form a protruding member;
A protruding member is fitted into the removed portion to form a male mold, and the material and heat treatment hardness of the protruding member can be freely selected as desired, improving usability. In addition, by cutting the protruding member with a cutting device such as a wire cutter, the finished dimensional accuracy of the protruding member is high, and compared to the conventional protruding member made of a plate-shaped body, the protruding member can be cut to the removed area of the intermediate plate. The fitting operation can be easily performed, which is advantageous in practice.
