The die-cutting plate substrate is also provided with a concave die hole, and a concave module is installed in the concave die hole.

[0004] In actual use, in order to ensure the effect of embossing, the mold closing pressure is usually relatively large. The embossing die-cutting plate disclosed in the above patent has the problem of excessive pressure during the mold closing process, which causes indentations on the outer side of the embossed pattern and affects the forming quality of the printed products. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a embossing printing plate to solve the problem of indentations on the outer side of the embossed printing pattern caused by excessive mold closing pressure in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides a die-cutting printing plate, including a steel base mold and a die. The steel base mold has a die-cutting area, and the die-cutting area has a tangent groove and a printing relief plate. The die has a die-cutting tool and a printing relief plate corresponding to the die-cutting area.

[0007] The printing plate is provided with a sponge block on the outside, which is used to buffer the impact force on the surface of the printed product during the process of the steel bottom mold and the die closing.

[0008] The steel bottom mold has a through hole in the area outside the printing plate, and a lifting adjustment mechanism is installed in the through hole. The sponge block is installed on the output end of the lifting adjustment mechanism.

[0009] In one embodiment of the present invention, the lifting adjustment mechanism includes a nut, a lead screw threaded through the nut, and a top plate disposed at the upper end of the lead screw, wherein the nut is fixedly installed in a through hole.

[0010] In one embodiment of this utility model, the sponge block is provided with adhesive backing, and the sponge block is detachably attached to the top plate by means of the adhesive backing.

[0011] In one embodiment of the present invention, at least four sponge blocks are provided on the outer side of a single printing plate, and the multiple sponge blocks are evenly distributed around the circumference of the printing plate.

[0012] In one embodiment of this utility model, in its natural state, the height of the sponge block is higher than the height of the printed graphics on the printed product.

[0013] In one embodiment of this utility model, both the through hole and the top plate are circular, and the top plate is rotatably fitted into the through hole.

[0014] In one embodiment of the present invention, the lower end of the top plate extends to the outside of the through hole, and an adjustment knob is provided at the lower end of the top plate.

[0015] As described above, the embossing printing plate of this utility model has the following beneficial effects:

[0016] This invention solves the problem of indentations on the outer periphery of the printing plate on the steel base mold by setting multiple sponge blocks on the outer side of the printing plate. These sponge blocks provide cushioning during the mold closing process between the steel base mold and the die, thus improving the forming quality of the embossed pattern due to excessive mold closing pressure. Simultaneously, the sponge blocks protect the mold closing structure on the printing plate, extending its service life. Furthermore, this invention includes a lifting and adjusting mechanism to adjust the cushioning height of the sponge blocks on the steel base mold, meeting the cushioning and protection needs of printed products of different thicknesses and improving the processing effect of the printed products.

[0023] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0024] Please see Figures 1 to 4 It should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that this utility model can produce, should still fall within the scope of the technical content disclosed in this utility model.

[0025] Example 1, please refer to Figures 1-4 This embodiment provides a embossing printing plate, which can be an integral printing plate or a multi-section printing plate. The embossing printing plate includes a steel base mold 1 and a die 2. The steel base mold 1 is provided with a die-cutting area 3, and the die-cutting area 3 is provided with a tangent groove 4 and a printing relief 5. The die 2 is provided with a die-cutting cutter 6 and a printing relief 7 corresponding to the die-cutting area 3. During the die-cutting process of the die 2 relative to the steel base mold 1, the die-cutting cutter 6 cuts into the tangent groove 4 to achieve die-cutting of the outer side of the printed product. At the same time, the printing relief 7 cooperates with the printing relief 5 to print graphics on the printed product.

[0026] The printing plate 5 has sponge blocks 8 on its outer side to cushion the impact on the surface of the printed product during the mold closing process of the steel base mold 1 and the die 2. At least four sponge blocks 8 are provided on the outer side of each printing plate 5, and these sponge blocks 8 are evenly distributed around the circumference of the printing plate 5. The height of the sponge blocks 8 is higher than the height of the printed image on the printed product. During the mold closing process, the steel base mold 1 and the die 2 can be cushioned by the sponge blocks 8, thus solving the problem of indentations on the outer side of the embossed pattern caused by excessive mold closing pressure during the embossing process, improving the forming quality of the embossed pattern. Simultaneously, the sponge blocks 8 also protect the mold closing structure on the printing plate, extending its service life. The sponge blocks 8 are provided with adhesive backing 10, allowing them to be detachably attached to the top plate 93 for quick replacement, ensuring the long-term cushioning effect of the printing plate.

[0027] The steel base mold 1 has a through hole 11 in the area outside the printing plate 5. A lifting adjustment mechanism 9 is installed in the through hole 11, and the sponge block 8 is installed on the output end of the lifting adjustment mechanism 9. Specifically, the lifting adjustment mechanism 9 includes a nut 91, a screw 92 threaded through the nut 91, and a top plate 93 located at the upper end of the screw 92. The nut 91 is fixedly installed in the through hole 11. By rotating the screw 92 from the lower end of the steel base mold 1, the screw 92 rotates and rises and falls in the nut 91, which drives the top plate 93 to rotate and rise and fall, thereby realizing the buffer height of the sponge block 8 on the steel base mold 1, meeting the buffer protection requirements of printed products of different thicknesses, and improving the processing effect of printed products.

[0028] In this embodiment, both the through hole 11 and the top plate 93 are circular. The top plate 93 is rotatably fitted into the through hole 11, which satisfies the requirement that the lead screw 92 drives the top plate 93 to rotate in the through hole 11 to adjust the buffer height of the sponge block 8. The lower end of the top plate 93 extends to the outside of the through hole 11, and the lower end of the top plate 93 is provided with an adjustment knob 94, which is convenient for workers to operate the adjustment knob 94 to adjust the screw 92 to rotate in the nut 91.

[0029] Example 2, based on Example 1, further illustrates this embodiment by designing the through hole 11 and the top plate 93 as squares. Since the lead screw 92 rotates within the nut 91, a rotating connector can be provided at the upper end of the lead screw 92. The top plate 93 is rotatably connected to the lead screw 92 via this connector. By rotating the lead screw 92 from the lower end of the steel base mold 1, the lead screw 92 rotates and rises within the nut 91, while the upper end of the lead screw 92 rotates within the rotating connector, thereby causing the top plate 93 to rise and fall. This achieves the desired buffer height for the sponge block 8 on the steel base mold 1, meeting the buffer protection requirements for printed products of varying thicknesses and improving the processing effect of the printed products.

[0030] In summary, the embossing printing plate provided by this utility model, with its sponge block 8, can form a buffer during the mold closing process, preventing indentations on the outer side of the embossed pattern caused by excessive mold closing pressure, thus improving the forming quality of the embossed printed product. The lifting and adjusting mechanism 9 can adjust the buffer height of the sponge block 8 on the steel base mold 1, thereby meeting the buffering and protection needs of printed products of different thicknesses and improving the processing effect of the printed product. Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0031] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
