2. Description of the Related Art Conventionally, when a film-shaped article such as a liquid crystal film, paper (corrugated cardboard), thin plate (metal foil) or the like is cut into a predetermined shape, a cutting having a cutting blade adapted to the shape to be cut. It is common to use equipment.

[0003] In order to manufacture relatively inexpensive articles, it is necessary to make inexpensive molds inexpensive.
A structure is employed in which a cutting blade is embedded in a relatively inexpensive and easy-to-process member such as plywood.

Furthermore, when a punched product (article to be cut) is mounted on a part of another device or the like, the mounting direction and high dimensional accuracy may be required. In such a case, it is common practice to form an uneven portion on the product, or to form a mounting hole or the like.

[0005] Therefore, in the die removal, a circular forming blade is embedded in the plywood in order to form a portion where the cutting blade is bent in a complicated manner and a hole for mounting. Conventionally, these cutting blades and circular forming blades have been manually bent and embedded in plywood according to the shape of the article to be cut.

For example, embedding a pin-shaped forming blade for forming a circular hole, or bending a long cutting blade into the holding groove,
Since it is manually embedded in the plywood (wooden mounting member), it takes time and effort to perform the mounting operation, particularly in a portion having a complicated shape such as the mounting portion of the article to be cut. In the case where there are a plurality of blades, it has been difficult to accurately determine not only the distance (dimension) between these forming blades but also the distance between the cutting blade and the forming blade.

It is also conceivable to simplify the work of mounting the cutting blade by blocking the complicatedly shaped portion of the cutting blade or the portion where the pin-shaped forming blade is provided. However, when a part of the cutting die is made into a block, it is necessary to precisely align the cutting blade provided on the block with another partial cutting blade, because the cutting die body is made of wood, so that minute and accurate processing is required. It was difficult and extremely difficult. In particular, if the work of re-polishing and reattaching the cutting blades is repeated, the height of the cutting blades is changed, and the portion where the block is to be mounted is likely to be loosened, so that the cutting blades are connected to each other (seam of the cutting blades).
Is concerned about the occurrence of misalignment.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has as its object the object of the present invention is to remove the cutting blade even when adopting a block type in which the mounting operation of the cutting blade can be performed without any trouble in the die removal.
