They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction and be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1-4 As shown, the integrated punching and waste discharge cutting die 5 of the utility model comprises an upper die 4, a middle die 2 and a lower die 1 which cooperate with each other, the lower die 1 comprises a mounting plate 11, a support plate 12 and a bottom plate 13, the mounting plate 11, the support plate 12 and the bottom plate 13 are made of wood; the support plate 12 is mounted between the mounting plate 11 and the bottom plate 13, the cutting die 5 is mounted on the mounting plate 11, and a discharge hole 6 for discharge is also provided on the lower die 1 inside the cutting die 5, the cutting die 5 is arranged on the mounting plate 11 as required according to the shape of the product, and discharge holes 6 may also be arranged between the cutting die 5, and the discharge holes 6 pass through the mounting plate 11, the support plate 12 and the bottom plate 13.

[0023] like Figure 1-2 As shown, four suspension rods 3 are slidably installed on the lower die 1 around the cutting die 5, the top ends of the suspension rods 3 are fixedly installed on the middle die 2, the suspension rods 3 pass through the lower die 1, and the lower ends of the suspension rods 3 are installed with limiting nuts 31. The middle die 2 is provided with a punching groove 21 that cooperates with the cutting die 5, and the cutting die 5 can pass through the punching groove 21; the material of the middle die 2 is a hard metal plate, such as a steel plate, which is convenient for installing the lower die 1 and the middle die 2 on a punching machine for use.
