Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging material processing, in particular to a concave-convex pressing component. Background Art
[0002] On the outer packaging of high-end products such as cosmetics and health products, we often see Figure 1 As shown in the processing requirements of embossing and debossing being tangent, if the existing embossing and debossing one-step forming process is used for processing, since the embossing and debossing are tangent, near the tangent point, the paper needs to deal with embossing and debossing at the same time. The large height difference between embossing and debossing will exceed the paper's ability to withstand deformation, causing the paper material to easily break. Therefore, it can only be processed in two operations, which will cause the following two problems: on the one hand, separate operations will lead to a significant increase in costs, and on the other hand, the positioning error caused by the second machine will affect product quality.
[0003] Therefore, it is necessary to provide a denting and embossing component to solve the above problems. Utility Model Content
[0004] The utility model provides a concave-convex pressing component, comprising:
[0005] An upper mold plate, wherein a female die for embossing and a male die for embossing are arranged on the upper mold plate, wherein the female die for embossing and the male die for embossing are connected via a tangent point, and when the distance between the male die for embossing and the female die for embossing is ≤ d, the height difference between the male die for embossing and the female die for embossing is reduced; and
[0006] The lower template is provided with a concave male mold and a convex female mold, the concave male mold matches the concave female mold, and the convex male mold matches the convex female mold.
[0007] In one embodiment, the height difference is reduced in a gradual manner.
[0008] In one embodiment, reducing the height difference between the embossing male die and the embossing female die specifically includes reducing the protruding height of the embossing male die.
[0009] In one embodiment, the height of the embossing die at the tangent point is 0.
[0010] In one embodiment, reducing the height difference between the embossing male die and the embossing female die specifically includes reducing the depression depth of the embossing female die.
[0011] In one embodiment, the depression depth of the embossing die at the tangent point is 0.
[0012] In one embodiment, 2 mm ≤ d ≤ 10 mm.
[0013] In one embodiment, 5 mm≤d≤10 mm.
[0014] In one embodiment, the female embossing die is made of steel, and the male embossing die is made of copper.
[0015] In one embodiment, the embossing positive die is circular.
[0016] The above-mentioned embossing and debossing component, when the distance between the embossing male die and the embossing female die is ≤ d, reduces the height difference between the embossing male die and the embossing female die, so that near the tangent point, the height difference between embossing and debossing does not exceed the ultimate bearing capacity of paper deformation, ensuring that the paper will not break. In addition, during operation, since the embossing and debossing operations are formed in one step, the operation cost is greatly reduced; at the same time, the positioning error caused by the secondary operation is avoided, ensuring product quality.

[0025] To make the above objects, features, and advantages of the present utility model more apparent and understandable, the following provides a detailed description of the specific embodiments of the present utility model in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0026] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" or "communicated with" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "upper", "lower", "vertical", "horizontal", "left", "right", and similar expressions used herein are only for illustrative purposes and do not represent the only embodiments.
[0027] The following mainly further details the concave pressing and convex punching assembly in conjunction with the accompanying drawings and specific embodiments.
[0028] Please refer to Figures 2 to 4 , a concave pressing and convex punching assembly of an embodiment includes an upper template 10 and a lower template 20.
[0029] The upper template 10 includes a first plate base 11. A concave pressing female die 12 and a convex punching male die 13 are provided on the first plate base 11, and the concave pressing female die 12 and the convex punching male die 13 are connected by a tangent point. The first plate base 11 is used to carry the concave pressing female die 12 and the convex punching male die 13. When the distance between the convex punching male die 13 and the concave pressing female die 12 ≤ d, the height difference between the convex punching male die 13 and the concave pressing female die 12 is reduced.
[0030] Optionally, the materials used to prepare the first plate base 11 include but are not limited to: steel plates, copper plates, and aluminum plates.
[0031] Preferably, the first plate base 11 is made of a steel plate. Since the steel plate has a high hardness, it can withstand a large pressure for a long time without deformation during the concave pressing operation, which is beneficial to extending the service life of the upper template 10.
[0032] Optionally, the concave pressing female die 12 is obtained by engraving or etching the first plate base 11 to make a local depression of the first plate base 11.
[0033] In this embodiment, the concave pressing female die 12 is obtained by engraving the first plate base 11.
[0034] Optionally, the cross-sectional shape of the concave pressing female die 12 is in a U shape, a 凵 shape, or an inverted trapezoid.
[0035] Preferably, the cross-sectional shape of the embossing female mold 12 is an inverted trapezoid, which is convenient for processing and can prevent the paper from breaking due to stress concentration at the folded corners.
[0036] The embossing male mold 13 is fixedly connected to the first plate base 11 and extends in a direction away from the first plate base 11. The embossing male mold 13 is connected to the embossing female mold 12 through a tangent point. When the distance between the embossing male mold 13 and the embossing female mold 12 is ≤d, the height difference between the embossing male mold 13 and the embossing female mold 12 is reduced.
[0037] Preferably, 2mm≤d≤10mm. This range can ensure that the height difference of the embossing positive mold 13 is reduced more smoothly and has less impact on the process appearance.
[0038] Furthermore, 5 mm ≤ d ≤ 10 mm, and this range can ensure that the height difference of the embossing positive mold 13 is reduced and smoothly, and the visual impact on the process appearance is not obvious.
[0039] There are two situations to reduce the height difference between the embossing male die 13 and the embossing female die 12: one is to reduce the protruding height of the embossing male die 13, and the other is to reduce the recessed depth of the embossing female die 12.
[0040] In this implementation, see Figures 2 to 4 The way to reduce the height difference between the embossing male mold 13 and the embossing female mold 12 is to reduce the protruding height of the embossing male mold 13. By reducing the protruding height of the embossing male mold 13, the height difference between the embossing male mold 13 and the embossing female mold 12 can be reduced, thereby ensuring that the height difference does not exceed the ultimate bearing capacity of paper deformation.
[0041] In another embodiment, see Figures 5 to 8 The way to reduce the height difference between the embossing male mold 13 and the embossing female mold 12 is to reduce the depression depth of the embossing female mold 12. By reducing the depression depth of the embossing female mold 12, the height difference between the embossing male mold 13 and the embossing female mold 12 can also be reduced, thereby ensuring that the height difference does not exceed the ultimate tolerance of paper deformation.
[0042] Preferably, the height difference between the embossing male mold 13 and the debossing female mold 12 is reduced gradually. When the debossing and debossing operation is performed, the gradual reduction of the height difference can keep the embossed pattern intact while keeping the paper from breaking.
[0043] In the present embodiment, the protruding height of the embossing male die 13 at the tangent point is 0. At this time, the height difference between the embossing male die 13 and the embossing female die 12 is the recessed depth of the embossing female die 12 .
[0044] exist Figures 5 to 8In the embodiment shown, the depression depth of the embossing female die 12 at the tangent point is 0. At this time, the height difference between the embossing male die 13 and the embossing female die 12 is the protruding height of the embossing male die 13 .
[0045] In this embodiment, the embossing positive mold 13 is obtained by engraving the first plate base 11 .
[0046] In another embodiment, see Figure 5 and Figure 8 The embossing male mold 13 is engraved from a copper plate and fixed to the first plate base 11 by bolts. On the one hand, the copper plate has a moderate hardness and is suitable for engraving complex process patterns. On the other hand, the price of the copper plate is lower than that of the steel plate, and the use of the copper plate is conducive to reducing the cost of the embossing assembly.
[0047] In the present embodiment, the embossing positive mold 13 is circular, but it should be understood that the embossing positive mold 13 may also be elliptical or other irregular patterns.
[0048] The lower template 20 is provided with a concave male mold 22 and a embossing female mold 23. The concave male mold 22 matches the concave female mold 12. When the concave male mold 22 is combined with the concave female mold 12, the patterns of the two are complementary; the embossing male mold 13 matches the embossing female mold 23. When the embossing male mold 13 is combined with the embossing female mold 23, the patterns of the two are complementary.
[0049] Specifically, the lower mold plate 20 includes a second plate base 21 , on which a embossing male mold 22 and an embossing female mold 23 are provided. The second plate base 21 is used to carry the embossing male mold 22 and the embossing female mold 23 .
[0050] Optionally, the material used to prepare the second substrate 21 includes, but is not limited to: a steel plate, a copper plate, and an aluminum plate. In this embodiment, the second substrate 21 is made of a steel plate.
[0051] Optionally, the embossing positive mold 22 is obtained by carving the second plate base 21 so that the second plate base 21 is partially convex.
[0052] The embossing female mold 23 is fixedly connected to the second plate base 21 and is recessed into the first plate base 11 . The embossing female mold 23 is connected to the embossing male mold 22 via a tangent point, and the embossing male mold 13 matches the embossing female mold 23 .
[0053] In this embodiment, the embossing female mold 23 is obtained by carving the second plate base 21 .
[0054] In another embodiment, see Figure 5 and Figure 8 The embossing female mold 23 is obtained by engraving a copper plate and is fixed to the second plate base 21 by bolts.
[0055] The above-mentioned embossing component, the upper template 10 is fixed on the upper die base of the die-cutting machine, and the lower template 20 is fixed on the lower die base of the die-cutting machine. When the embossing operation is performed, the paper is set between the upper template 10 and the lower template 20. When the upper template 10 and the lower template 20 are engaged with each other, the embossing effect is presented on the paper due to the interaction between the upper template 10 and the lower template 20.
[0056] The above-mentioned embossing and debossing component, when the distance between the embossing male die 13 and the embossing female die 12 is ≤ d, reduces the height difference between the embossing male die 13 and the embossing female die 12, so that near the tangent point, the height difference between embossing and debossing does not exceed the ultimate bearing capacity of paper deformation, ensuring that the paper will not break. In addition, during operation, since the embossing and debossing operations are formed in one step, the operation cost is greatly reduced; at the same time, the positioning error caused by the secondary operation is avoided to ensure product quality.
[0057] The following are specific embodiments.
[0058] Example 1
[0059] See also Figures 2 to 4 The present embodiment provides a embossing assembly, including an upper template 10 and a lower template 20. The upper template 10 includes a first plate base 11, on which a embossing female mold 12 and an embossing male mold 13 are provided. The embossing female mold 12 and the embossing male mold 13 are connected by a tangent point. When the distance between the embossing male mold 13 and the embossing female mold 12 is ≤d, the height of the embossing male mold 13 is reduced. The lower template 20 includes a second plate base 21, on which a embossing male mold 22 and an embossing female mold 23 are provided. The embossing male mold 22 matches the embossing female mold 12, and the embossing male mold 13 matches the embossing female mold 23.
[0060] In this embodiment, the height difference between the embossing male mold 13 and the embossing female mold 12 is reduced by reducing the protrusion height d of the embossing male mold 13, and the embossing male mold 13 is 10 mm. The first plate base 11 is made of a steel plate, the embossing female mold 12 and the embossing male mold 13 are made by engraving a steel plate, and the second plate base 21 is made of a steel plate, and the embossing male mold 22 and the embossing female mold 23 are made by engraving a steel plate.
[0061] The above-mentioned embossing and debossing component, when the distance between the embossing male die 13 and the embossing female die 12 is ≤ d, reduces the height difference between the embossing male die 13 and the embossing female die 12, so that near the tangent point, the height difference between embossing and debossing does not exceed the ultimate bearing capacity of paper deformation, ensuring that the paper will not break. In addition, during operation, since the embossing and debossing operations are formed in one step, the operation cost is greatly reduced; at the same time, the positioning error caused by the secondary operation is avoided to ensure product quality.
[0062] Example 2
[0063] See also Figure 5and Figure 8 The embossing assembly provided in this embodiment is similar to the embossing assembly provided in Example 1, except that: (1) the height difference between the embossing male die 13 and the embossing female die 12 is reduced by reducing the depression depth of the embossing female die 12; (2) the embossing male die 13 is made of copper plate engraving and fixed to the first plate base 11 by bolts; (3) the embossing female die 23 is made of copper plate engraving and fixed to the second plate base 21 by bolts; (4) d is 5 mm.
[0064] The above-mentioned embossing assembly can also reduce the height difference between the embossing male die 13 and the embossing female die 12 by reducing the depression depth of the embossing female die 12, thereby ensuring that the height difference does not exceed the ultimate bearing capacity of paper deformation. In addition, copper is used to prepare the embossing male die 13 and the embossing female die 23. On the one hand, due to the moderate hardness of the copper plate, it is suitable for engraving complex process patterns. On the other hand, the price of copper plate is lower than that of steel plate, and the use of copper plate is conducive to reducing the cost of the embossing assembly.
