Thin plate cutting press mold having an inclination according to the present invention may have a structure in which the plate 110 and the cutting blade portion 120 are integrally manufactured by cutting and polishing a nonmetallic material, but have a structure as described above. According to the present invention, the thin plate cutting knife corresponding to the cutting blade part 120 may be manufactured separately from the plate 110 and then coupled to each other. Cutting knife for cutting thin plate which makes it possible to implement the press mold for another makes another technical gist.

The structure and shape of the thin plate cutting knife are described in detail in the description of the cutting blade unit 120 of the thin plate cutting press die, and the overlapping description thereof will be omitted. Since the coupling structure between the plates 110 is well known in the art, a detailed description of the connection portion with the plate 110 will be omitted.

When using a thin plate cutting press die having a slope as described above, and a cutting knife for cutting a thin plate, a thin plate material of metal or non-metal material, for example, a thin plate material 10 such as an LCD optical film is pressed into a press die ( In order to cut into a predetermined shape using 100, a sequential cutting step of sequentially pressing and cutting the thin plate material 10 from one side to the other side of the press mold 100 having a relatively extended protrusion length. The thin plate can be cut through, and the present invention makes this thin plate cutting method another technical gist.

When the embodiment in which the cutting blade 121 of the press die is formed to have a semi-elliptical longitudinal section shape is applied, sequential cutting from one side to the other side is performed in the sequential cutting step, and the thin plate material 10 is While being moved toward the plate 110 side of the press die, the curved surface of the cutting blade 121 is connected to the thin plate material cut surface 11 having an inclined straight or flat longitudinal cross-sectional shape with a minimized connection area Cutting and downward movement of the thin plate material 11 can be made.

Accordingly, when the press is cut in the past, pressing force is simultaneously transmitted over the entire cutting surface 11 of the thin plate material and prevents a phenomenon that the cutting blade is excessively loaded while being instantaneously cut, thereby cutting the cutting blade 121. ) Can reduce wear and improve durability.

In addition, air is naturally released between the cutting blade portion 120 and the thin plate material 10 having a downwardly inclined shape during the punching operation, and the cut surface of the thin plate material 10 comes out more neatly, and the upper and lower plates of the press are flat. Even if the degree does not fit to some extent, the punching work is possible.

In addition, by forming the cutting blade 121 to have a semi-elliptical longitudinal cross-sectional shape, the thin plate material cutting surface 11 in which the curved surface of the cutting blade 121 has an inclined straight or flat longitudinal cross-sectional shape. Compared to the cutting and downward movement of the cutting blade and the thin plate material 11, the cutting edge 11 and the thin plate material 11 are excessively friction-connected over the cutting plane 11 of the thin plate material. The load applied to the cutting blade 121 is evenly distributed along the curved surface having an extended surface area, and is sequentially connected to the cutting surface 11 of the thin plate material, thereby reducing wear of the cutting blade 121. Can be reduced.
