[0006] The front and back frames of the small knife mold are provided with concave steps, and the middle of the cushion block is provided with a receiving groove for installation at the bottom of the installation groove. The end surface of the cushion block is supported on the concave steps on the front and back sides of the small knife mold, and the bottom surface of the cushion block is flush with the back surface of the large knife mold.

[0007] Preferably, the shaft ends on the left and right sides of the small knife die are hemispherical and integrally formed, and the inner side of the installation groove of the large knife die is provided with a groove matching with it.

[0008] Preferably, the shaft ends on the left and right sides of the small knife die are short cylindrical ends, and the inner side of the installation groove of the large knife die is provided with a short cylindrical groove matching therewith.

[0009] Preferably, the front opening of the large knife die is connected to the short cylindrical groove.

[0010] The utility model has the following beneficial effects: convenient use, double-sided pattern of partial knife mold, fast switching without affecting the use of knife mold, and reducing the cost of processing knife mold. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Example 1

[0015] like Figure 1 , 2 As shown in Figure 3, a combined laser knife die comprises a large knife die 1, a small knife die 2 and a cushion block 3, wherein the large knife die 1 is provided with a mounting groove 4, and the small knife die 2 is rotatably mounted in the mounting groove 4 of the large knife die 1 through shaft ends 5 on the left and right sides; the small knife die 2 is provided with knife grooves on both the front and back sides; after the small knife die 2 is turned over, the blades 6 in the knife grooves on both the front and back sides extend out of the front side of the large knife die 1, and after the small knife die 2 is turned over, the blades 6 in the knife grooves on both the front and back sides are higher than the bottom of the mounting groove 4;

[0016] The front and back frames of the small knife mold 2 are provided with concave steps 7, and the middle of the cushion block 3 is provided with a receiving groove for installation at the bottom of the installation groove 4. The end faces of the cushion block 3 are supported on the concave steps 7 on the front and back sides of the small knife mold 2, and the bottom surface of the cushion block 3 is flush with the back surface of the large knife mold 1.

[0017] The shaft ends 5 on the left and right sides of the small knife die 2 are short cylindrical ends, and the inner side of the installation groove 4 of the large knife die 1 is provided with a short cylindrical groove matching therewith; the front opening 8 of the large knife die 1 is connected with the short cylindrical groove.

[0018] The utility model slots a large knife die 1 and reversibly installs a small knife die 2 with blades 6 on both sides, so that it can be quickly turned over for use. The installation slot 4 is relatively deep, and after the small knife die 2 is turned over, the blades 6 in the knife slots on both sides are higher than the bottom of the installation slot 4;

[0019] In order to prevent the small knife die 2 from turning over during use, it is not laborious, and the pad 3 for supporting the bottom is also needed. Its accommodating groove is used to accommodate the blade 6 on the reverse side, and the end face is used to support the small knife die 2.

[0020] There are two ways to replace, one is to lift the large knife die 1 and flip the small knife die 2 to switch. The other is that in this embodiment, the front opening 8 of the large knife die 1 is connected with the short cylindrical groove, and the small knife die 2 is directly taken out from the front and flipped, and then the short cylindrical end of the small knife die 2 is inserted into the short cylindrical groove along the opening 8. Compared with the semicircular protrusion, the cylindrical groove has a better introduction effect.

[0021] In summary, fast switching is achieved without affecting the use of large and small cutting dies, thereby reducing the cost of processing cutting dies.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
