DETAILED DESCRIPTION

[0025] The utility model is described in detail below in combination with the drawings.

[0026] Referring to Figures 1 to 4 The utility model discloses a thick material engraving die die of die cutting printing, including upper die holder 1, lower die holder 2, ejector block 3 and high-strength elastic glue 4, wherein high-strength elastic glue, also called polyurethane PU elastomer, is a kind of new material between plastic and rubber with good strength and small compression deformation, with the rigidity of plastic, and the elasticity of rubber new material.In this embodiment, the high-strength elastic glue parameter is: ∮12*long 12, and the hardness is: 90A.

[0027] Lower die holder 2 is internally provided with fixed cavity 21.

[0028] Upper die holder 1 cover is set at the top of fixed cavity 21 and seals fixed cavity 21, and the top of upper die holder 1 is provided with cutter 11 for die cutting product, and cutter 11 is internally provided with cutter cavity 12 in communication with the inside of fixed cavity 21.

[0029] High-strength elastic glue 4 is arranged between ejector block 3 and fixed cavity 21 and drives ejector block 3 to slide along cutter cavity 12 for ejecting the product in cutter 11 by elastic force.

[0030] The design effectively drives ejector block 3 to slide along cutter cavity 12 by the elastic force of high-strength elastic glue 4, so that the product in cutter 11 can be easily ejected.This design improves the efficiency of product demolding and reduces the complexity of manual operation.

[0031] Upper die holder 1 and lower die holder 2 are sealed by fixed cavity 21 and the design of upper die holder 1 cover, so that the whole die structure is compact and stable.This design not only improves the durability of the die, but also makes the die more stable during die cutting, improving the processing precision of the product.

[0032] Since the die structure is clear and the connection relationship between each component is clear, when the die fails or needs to be maintained, the problem can be quickly located and repaired.This design reduces the maintenance cost of the die and improves the production efficiency.

[0033] In the die cutting process, the cutter 11 cuts the product and leaves it in the cutter cavity 12. In order to eject the product from the cutter 11, the elastic glue 4 is arranged between the ejector block 3 and the fixed cavity 21. The elastic force of the elastic glue 4 drives the ejector block 3 to slide along the cutter cavity 12, thereby ejecting the product from the cutter 11. This design not only improves the efficiency of product demolding, but also ensures the integrity and quality of the product.

[0034] The mold realizes efficient and stable product demolding under the elastic force of the elastic glue 4 through reasonable structural design of the upper mold base 1, the lower mold base 2, the ejector block 3 and the elastic glue 4. The product is quickly ejected from the cutter cavity, and the ejector block 3 is completely reset, which is not easy to cause the problems of knife explosion, product edge with pressure mark, white edge and other appearance problems.

[0035] Referring to Figure 4 As shown in the figure, the ejector block 3 of the embodiment includes a limiting block 31 and an ejecting column 32, the ejecting column 32 is arranged at the top of the limiting block 31, and the bottom of the limiting block 31 is provided with a fixed groove 311, the top of the elastic glue 4 is connected with the limiting block 31 in close fit through the fixed groove 311.

[0036] Through the design of the limiting block 31 and the ejecting column 32, the overall structure of the ejector block 3 is more stable, which can provide stable support and ejecting force during work.

[0037] The fixed groove 311 arranged at the bottom of the limiting block 31 closely fits with the top of the elastic glue 4, which ensures that the connection between them is stable and not easy to loosen, and improves the overall stability and durability.

[0038] Specifically, the cross section of the limiting block 31 is larger than that of the cutter cavity 12, which prevents the limiting block 31 from entering the cutter cavity 12.

[0039] Preferably, a buffer ring 33 is arranged at the connection between the ejecting column 32 and the limiting block 31, which prevents the limiting block 31 from colliding with the cover of the upper mold base 1.

[0040] Referring to Figure 4 As shown in the figure, the fixed groove 311 is provided with a matching cavity 312, which increases the close fitting area of the elastic glue 4 and the fixed groove 311 through the matching cavity 312.

[0041] One side of the matching cavity 312 is provided with an exhaust groove 313, which facilitates the exhaust of air inside the matching cavity 312 when the elastic glue 4 closely fits with the fixed groove 311, so that the elastic glue 4 and the inner wall of the fixed groove 311 closely fit more tightly.

[0042] Referring to Figure 3As shown, the fixed cavity 21 of the embodiment is provided with a limiting groove 22 corresponding to the elastic glue 4, and the elastic glue 4 is inserted into the limiting groove 22 to prevent displacement of the elastic glue 4 under pressure through the limiting groove 22.

[0043] Preferably, the bottom of the elastic glue 4 is provided with a bottom sleeve 41, which is sleeved on the bottom of the elastic glue 4 to prevent deformation of the bottom of the elastic glue 4 through the bottom sleeve 41. The bottom sleeve 41 is inserted into the limiting groove 22, and the limiting groove 22 and the bottom sleeve 41 are matched to connect the elastic glue 4 with the lower die seat 2, so that the elastic glue 4 is less likely to displace when under pressure.

[0044] The distance between the outer side surface of the ejection column 32 and the inner wall of the knife cavity 12 is 0.005-0.01 MM.

[0045] The distance between the outer side surface of the ejection column 32 and the inner wall of the knife cavity 12 is precisely controlled within the range of 0.005-0.01 MM. This small gap ensures that the ejection column can tightly fit the inner wall of the knife cavity when ejecting the product, realizes precise ejection, and avoids the product from deviating or being damaged during the ejection process. In the embodiment, the distance between the outer side surface of the ejection column 32 and the inner wall of the knife cavity 12 is precisely controlled to 0.01 MM to realize precise ejection of the product.

[0046] Although the distance is very small, this design can still reduce the friction between the ejection column and the inner wall of the knife cavity to some extent, reduce the energy consumption and wear during the ejection process, and prolong the service life of the mold.

[0047] The small distance helps to maintain the sealing between the ejection column and the inner wall of the knife cavity, prevents foreign matter or liquid from penetrating during the die cutting or ejection process, maintains the cleanliness and dryness of the inside of the mold, and ensures the processing quality of the product.

[0048] The height of the ejection block 3 and the elastic glue 4 of the embodiment is 0.1-1.3 MM higher than the top surface of the cutter 11.

[0049] The height of the ejection block 3 and the elastic glue 4 is 0.1-1.3 MM higher than the top surface of the cutter 11. This design ensures that the ejection column 32 can fully contact the bottom of the product when ejecting the product, provides sufficient ejection force, and avoids the product from not being completely ejected or deviating during the ejection process. In the embodiment, the height of the ejection block 3 and the elastic glue 4 is 0.1 MM higher than the top surface of the cutter 11.

[0050] This design enables the mold to adapt to products of different thicknesses and sizes, and precise ejection of different products can be realized by adjusting the height of the ejection block 3 and the elastic glue 4.

[0051] Referring to Figure 2As shown, the cutter 11 of the embodiment comprises a cutter body 13, the cutter body 13 comprises an inner flank surface 131, an inclined flank surface 132 and an outer flank surface 133, the inner flank surface 131 and the outer flank surface 133 are both annular, and the inclined flank surface 132 is obliquely connected between the inner flank surface 131 and the outer flank surface 133;

[0052] The height of the inner flank surface 131 is higher than the height of the outer flank surface 133.

[0053] The cutter 11 is designed to connect the inner flank surface 131 and the outer flank surface 133 through the inclined flank surface 132, and such a structure is helpful to more effectively disperse the cutting force in the cutting process, reduce the cutting resistance, and thus improve the cutting efficiency.

[0054] Due to the height of the inner flank surface 131 being higher than the height of the outer flank surface 133, the inclined flank surface 132 is oblique, and such a design is helpful to form a smoother cutting path in the cutting process, reduce the generation of cutting vibration and burrs, and thus improve the smoothness and precision of the cutting surface.

[0055] The above is only the preferred embodiment of the utility model, and for the ordinary skilled in the art, according to the thought of the utility model, the specific implementation mode and the application range will have the change, and the content of the specification should not be understood as the limitation of the utility model.
