Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a die-cutting mold. Background Technology

[0002] In today's packaging market, the design of mid-to-high-end packaging boxes often incorporates embossing technology. Embossing is used to create raised patterns or text on the surface of the packaging box to enhance its texture and visual appeal, thereby attracting consumers' attention.

[0003] However, in traditional packaging box production processes, the embossing process is usually completed before the die-cutting process. This step-by-step production model has many drawbacks, mainly in terms of low efficiency and high cost. Specifically, each process change requires readjustment of equipment and molds, which not only consumes a lot of manpower and time but also extends the production cycle, thereby increasing inventory costs. In addition, after the embossing process is completed, there is still a waiting period before the die-cutting process is scheduled, and this accumulated waiting time further reduces overall production efficiency.

[0004] The content of the background section is merely the technology known to the inventor and does not necessarily represent the prior art in this field. Utility Model Content

[0038] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0039] Figure 1 A schematic diagram of a die-cutting mold 100 according to an embodiment of the present invention is shown below, in conjunction with... Figure 1 Provide a detailed description.

[0040] like Figure 1 As shown, the die-cutting mold 100 includes a movable mold 110 and a fixed mold 120. The movable mold 110 is positioned above the fixed mold 120, and the fixed mold 120 can move up and down reciprocally with the help of mechanical equipment. During this process, the movable mold 110 and the fixed mold 120 cooperate with each other to accurately complete the embossing and die-cutting of paper (cardboard). Figure 2 A schematic diagram of a moving model 110 according to an embodiment of the present invention is shown. Figure 1 and Figure 2 As shown, the moving mold 110 mainly includes a moving template 111, a cutter 112 (shown as solid lines in the figure), a pad 113, and a concave plate 114. The moving template 111 has a first working surface 111a. Figure 1The lower surface of the moving template 111 has multiple connecting holes 111b spaced apart on its first working surface 111a. These connecting holes 111b are all threaded holes. The cutter 112 is connected to the first working surface 111a of the moving template 111 and is used to cooperate with the fixed mold 120 to perform die cutting on the paper. Figure 3 A schematic diagram of a pad 113 according to an embodiment of the present invention is shown, as follows: Figures 1 to 3 As shown, the pad 113 is connected to the first working surface 111a of the moving template 111 by one or more fixing bolts 115. Specifically, the pad 113 is provided with a countersunk hole 113a, and the fixing bolt 115 passes through the countersunk hole 113a through the pad 113 and is screwed into the corresponding connecting hole 111b (the fixing bolt 115 and the connecting hole 111b are threadedly connected), thereby firmly fixing the pad 113 to the moving template 111. The concave plate 114 has a second working surface 114a ( Figure 1 The lower surface of the concave plate 114 has a groove 114b on its second working surface 114a. The shape of the groove 114b matches the shape of the embossing pattern, ensuring that the required pattern outline can be accurately formed during the embossing process. The concave plate 114 is connected to the pad 113 through a buffer structure 116, allowing the concave plate 114 to float relative to the pad 113. This allows embossing to be performed before die-cutting, avoiding problems such as wrinkling, tearing, or deformation of the cardboard due to excessive pressure, and ensuring the appearance quality and consistency of the product. Figure 4 A schematic diagram of a mold 120 according to an embodiment of the present invention is shown. Figure 4 As shown, the fixed mold 120 includes a fixed template 121 and a protruding plate 122, wherein the fixed template 121 has a third working surface 121a ( Figure 1 The upper surface of the die 110 is connected to the third working surface 121a of the fixed die 121, and the position and shape of the protruding plate 122 are adapted to the groove 114b on the concave plate 114. During the closing process of the moving die 110 and the fixed die 120, firstly, the protruding plate 122 and the concave plate 114 cooperate to emboss the paper; then, the cutter 112 cooperates with the fixed die 121 to die-cut the paper.

[0041] Furthermore, the number of connecting holes 111b is far greater than the number of fixing bolts 115. This allows users to easily replace the concave plate 114 and the pad 113, or adjust the position of the concave plate 114 and the pad 113 according to the design requirements of different products, thereby enabling multiple products to share the same set of moving templates 111, which helps to reduce production costs.

[0042] According to one embodiment of the present invention, such as Figure 3 As shown, one or more positioning holes 113b are provided on the pad 113. Accordingly, as Figure 2As shown, multiple positioning protrusions 117 are also provided on the first working surface 111a of the moving template 111. The positioning protrusions 117 can be arranged between four adjacent connecting holes 111b. The positioning protrusions 117 cooperate with the positioning holes 113b to achieve accurate positioning of the pad 113 on the moving template 111, thereby ensuring the accurate installation of the concave plate 114.

[0043] According to one embodiment of the present invention, such as Figure 2 As shown, the cutter 112 forms a closed die-cutting area on the first working surface 111a of the moving template 111. After die-cutting, the outline shape of the finished product will be highly consistent with the outline shape of the die-cutting area. The aforementioned multiple connecting holes 111b are all located within the die-cutting area and are distributed in an array (e.g., a rectangular array). This array-type layout of connecting holes 111b can provide flexible fixing points for the installation of the concave plate 114 and the pad 113, allowing users to quickly and conveniently adjust the position, orientation, etc. of the concave plate 114 and the pad 113 according to different product design requirements.

[0044] According to one embodiment of the present invention, such as Figure 2 and Figure 4 As shown, the moving die 110 also includes pressure knives 118 (shown as dashed lines in the figure), all of which are connected to the first working surface 111a of the moving die 111 and located within the die-cutting area. Correspondingly, a creasing groove 123 (shown as dashed lines in the figure) is provided on the third working surface 121a of the fixed die 121, and the creasing groove 123 is aligned with the pressure knives 118. During the closing process of the moving die 110 and the fixed die 120, the pressure knives 118 and the creasing grooves 123 cooperate to form creasing on the paper. These creasing can provide clear crease lines in subsequent processes, thereby ensuring the convenience and accuracy of the paper folding process. Optionally, multiple pressure knives 118 and creasing grooves 123 can be provided to meet the requirements of complex folding structures.

[0045] According to one embodiment of the present invention, such as Figure 1 and Figure 5As shown, a first mounting hole 113c is provided on the pad 113, and a second mounting hole 114c is provided on the concave plate 114. The first mounting hole 113c and the second mounting hole 114c are aligned with each other and are both threaded holes. The buffer structure 116 includes a first connecting member 116a, a second connecting member 116b, and a spring 116c. The first connecting member 116a and the second connecting member 116b can connect the concave plate 114 and the pad 113, and ensure that the concave plate 114 can float relative to the pad 113. Specifically: the first connecting member 116a has a cylindrical structure with threads on its exterior, and is threadedly connected to the first mounting hole 113c based on these threads. The second connecting member 116b has a columnar structure with threads at one end, and is threadedly connected to the second mounting hole 114c based on these threads. The other end of the second connecting member 116b can be movably inserted into the first connecting member 116a. Furthermore, a first anti-detachment flange 116d is provided inside the first connecting member 116a, and a second anti-detachment flange 116e is provided outside the second connecting member 116b. The first anti-detachment flange 116d and the second anti-detachment flange 116e cooperate with each other to effectively prevent the second connecting member 116b from falling out of the first connecting member 116a, thus realizing the connection between the first connecting member 116a and the second connecting member 116b, and also realizing the connection between the concave plate 114 and the pad block 113. Preferably, the first anti-detachment flange 116d is located at the lower end of the first connecting member 116a, and the second anti-detachment flange 116e is located at the upper end of the second connecting member 116b, so that the concave plate 114 has a larger floating stroke. Figure 5 As shown, spring 116c is connected between pad 113 and concave plate 114 to provide sufficient support force for concave plate 114, ensuring the quality of the dent. Preferably, spring 116c is sleeved on the outside of the first connector 116a and the second connector 116b.

[0046] Those skilled in the art will readily understand that while the specific form of the buffer structure 116 has been described above, its design is not limited to this one. In other embodiments, the buffer structure 116 can adopt various other structural forms. For example, in some embodiments, the buffer structure 116 may include buffer pads, such as silicone pads or rubber pads, which are fixed between the pad block 113 and the concave plate 114 by adhesive bonding, thereby achieving the buffering function and ensuring that the concave plate 114 can float relative to the pad block 113.

[0047] According to one embodiment of the present invention, such as Figure 4As shown, the protruding plate 122 is bonded and fixed to the fixed template 121. This allows users to easily replace the protruding plate 122 or adjust its position according to the design requirements of different products, thereby enabling multiple products to share the same fixed template 121, which helps reduce production costs. Those skilled in the art will readily understand that in other embodiments, the protruding plate 122 and the fixed template 121 can also be integrally formed.

[0048] Compared with the prior art, the embodiments of this utility model provide a die-cutting mold 100, which can simultaneously realize the functions of embossing and die-cutting, avoiding the problems of equipment adjustment, mold replacement and process waiting caused by step-by-step production in the prior art, thereby greatly shortening the production cycle, reducing labor and time costs, and also reducing the risk of inventory backlog caused by process change.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
