Among these metal forming methods, the press mold generally refers to a process in which energy is applied to a material to transform it into a desired shape. In a modern industrial society, a product is manufactured using various processing methods, and a new processing method and a processing machine are used.

Among various processing methods, press working refers to a work of cutting or forming a material by using a press machine and a special tool such as a mold. As a result, a plastic working process mainly involving cold working is generally used.

More specifically, the press processing has the following excellent characteristics in comparison with other processing methods. ① The strength of the product is high and lightweight. ② The utilization rate of materials is good. ③ Highly productive process. ④ It is possible to produce large quantity of product with high degree of uniformity.

On the other hand, a mold apparatus used in a general press die includes a piercing mold and a trimming mold.

The piercing mold is a punching work from the material to be used. This work is called punching. It is the same as the blanking mold at the point of shearing at the outline of the closed curve. .

A trimming mold is a mold used to cut an irregular edge portion of a molded product, and to process a finished product by shearing the edge of a product that has undergone a drawing forming process as a required phenomenon.

Conventional press dies have separate piercing mold apparatuses and trimming mold apparatuses, and the piercing mold apparatus has a function of punching holes of metal, and the trimming mold apparatus has a function of cutting according to the shape and size of the metal.

However, in the conventional press mold, there is a problem in that the piercing and trimming processes are carried out, and the manufacturing cost is increased by disposing the piercing mold device and the trimming mold device separately. Further, in each of the mold devices, There is a problem that the process time also increases.
