Description

Technical Field

[0001] This utility model relates to a die-cutting mold, specifically a combined die-cutting mold. Background Technology

[0002] In the processing of footwear, bags, leather goods, and other products, die-cutting dies are essential tools for cutting materials. Currently, most die-cutting dies on the market are of a single, fixed structure, with their dimensions predetermined before production. This structure has significant drawbacks in practical use: firstly, when cutting workpieces of different sizes, the entire die-cutting set must be replaced, making the process cumbersome and time-consuming; secondly, manufacturing companies need to equip themselves with multiple sets of dies of different specifications to meet production demands, increasing procurement costs. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention aims to provide a modular die-cutting mold that allows for flexible adjustment of die-cutting mold dimensions and reduces costs.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A modular die-cutting mold includes a detachably connected die-cutting mold base and a die-cutting segment module. The die-cutting mold base and the die-cutting segment module are joined together along the length direction to form an elongated structure. Both the die-cutting mold base and the die-cutting segment module are provided with cutting blades. The cutting blades of the die-cutting mold base and the cutting blades of the die-cutting segment module together form a continuous cutting edge.

[0005] As a limitation of this utility model: the die holder includes a die head, which includes a first protrusion, a second protrusion, a third protrusion and a fourth protrusion that are fixedly connected in sequence. The first protrusion, the second protrusion, the third protrusion and the fourth protrusion are distributed in a finger-like shape. The tail ends of the first protrusion and the fourth protrusion are detachably connected to the die segment module. Each of the first protrusion, the second protrusion, the third protrusion and the fourth protrusion is provided with a cutting blade.

[0006] As a further limitation of this utility model: the first protrusion, the second protrusion, the third protrusion and the fourth protrusion are all configured as hollow structures, and the hollow areas of the first protrusion, the second protrusion, the third protrusion and the fourth protrusion all constitute a receiving cavity for accommodating the cutting material.

[0007] As a further limitation of this utility model: the tail ends of the first protrusion, the second protrusion, the third protrusion and the fourth protrusion are connected to a reinforcing rod, and a gap is left between the reinforcing rod and the cutting edge of the die holder.

[0008] As another limitation of this utility model: a connecting component is provided between the cutting segment module and the die holder. The connecting component includes a connecting plate, bolts and nuts. The connecting plate is fixedly connected to the die holder. The bolts pass through the connecting plate and the cutting segment module and are fastened by the nuts. Gaps are left between the connecting plate and the cutting edge of the die holder, and between the connecting plate and the cutting edge of the cutting segment module.

[0009] As a further limitation of this utility model: the blade module is a U-shaped plate, and a first support plate and a second support plate extending along its width direction are provided at intervals in its U-shaped groove; gaps are left between the first support plate and the cutting edge of the blade module, and between the second support plate and the cutting edge of the blade module.

[0010] As a further limitation of this utility model: the die holder and the die segment module are both made of cemented carbide material.

[0011] By adopting the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows: In this invention, the die holder and die segment modules are detachably connected. By replacing die segment modules of different lengths with the fixed die holder, a continuous cutting edge of the required total length can be quickly formed. This enables flexible and continuous adjustment of the die size, effectively improving operational efficiency. Enterprises no longer need to purchase an entire die set for every minor dimensional change; they only need to stock a standard die holder and a series of die segment modules of different lengths. These can be arranged and combined to meet various production needs, significantly reducing the total number of dies and directly lowering equipment purchase and warehousing costs.

[0012] In summary, this utility model allows for flexible adjustment of the die size and reduces equipment purchase and warehousing management costs for enterprises; this utility model is applicable to the cutting of materials such as shoes, bags, and leather goods. Attached Figure Description

Detailed Implementation

[0016] 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 do not constitute a limitation thereof.

[0017] The directional terms or positional relationships such as "length direction" and "width direction" used in the embodiments are based on the drawings in this utility model specification. Figure 5 The orientation relationships are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model.

[0018] like Figures 1 to 8 As shown, this embodiment includes a detachably connected die holder 1 and a die segment module 2. The die holder 1 is fixed, and the die segment module 2 has multiple different sizes. By replacing the die segment module 2 with different lengths, it can be connected with the fixed die holder 1 along the length direction to form an extended structure, thereby quickly forming a continuous cutting edge of the required total length, realizing flexible and continuous adjustment of the die size.

[0019] like Figure 2 As shown, both the die holder 1 and the cutting segment module 2 are provided with cutting blades 3. The cutting blades 3 of the die holder 1 and the cutting blades 3 of the cutting segment module 2 together form a continuous cutting edge. The cutting blades 3 here are formed by sharpening the cutting end of the die holder 1 and the cutting segment module 2.

[0020] like Figure 3 As shown, the die holder 1 includes a die head 4 and a reinforcing rod 5.

[0021] The die head 4 includes a first protrusion 41, a second protrusion 42, a third protrusion 43, and a fourth protrusion 44, which are sequentially fixedly connected by welding. The first protrusion 41, the second protrusion 42, the third protrusion 43, and the fourth protrusion 44 are distributed in a finger-like shape, similar to the shape of the four fingers excluding the thumb. The tail ends 6 of the first protrusion 41 and the fourth protrusion 44 are detachably connected to the die segment module 2. An extension plate 7 is integrally provided on the tail end 6 of the fourth protrusion 44, which is used for detachable connection with the die segment module 2. Each of the first protrusion 41, the second protrusion 42, the third protrusion 43, and the fourth protrusion 44 is provided with a cutting blade 3.

[0022] Furthermore, the first protrusion 41, the second protrusion 42, the third protrusion 43, and the fourth protrusion 44 are all designed with a hollow structure. The hollow areas of the first protrusion 41, the second protrusion 42, the third protrusion 43, and the fourth protrusion 44 all constitute a receiving cavity 8 for accommodating the cut material. At the moment the material 15 is cut, the cut material 15 will directly enter the receiving cavity 8, at which time the cut material 15 can be separated from the parent material.

[0023] The tail ends 6 of the first protrusion 41, the second protrusion 42, the third protrusion 43, and the fourth protrusion 44 are connected to the reinforcing rod 5. Since the material 15 needs to be cut by pressing down during cutting, the material 15 is cut off by the cutting blade 3. Compared with the tail ends 6 of the first protrusion 41, the second protrusion 42, the third protrusion 43, and the fourth protrusion 44 being in a free state, the reinforcing rod 5 can better prevent the first protrusion 41 to the fourth protrusion 44 from deforming under force, thus increasing the structural strength.

[0024] A gap 14 is left between the reinforcing rod 5 and the cutting edge 3 of the die holder 1. If the reinforcing rod 5 is flush with the cutting edge 3, then when cutting the material 15, the reinforcing rod 5 will press against the material 15, resulting in incomplete cutting of the material 15. Figure 6 , 7 As shown, gap 14 refers to the distance between the reinforcing rod 5 and the surface of material 15.

[0025] The detachable connection between the die holder 1 and the die segment module 2 is as follows: Figure 1 As shown, a connecting assembly is provided between the cutting segment module 2 and the die holder 1. The connecting assembly includes a connecting plate 9, a bolt 10, and a nut 11. The connecting plate 9 is welded and fixed to the die holder 1. The bolt 10 passes through the connecting plate 9 and the cutting segment module 2 and is tightened on the other side by the nut 11. After tightening, the cutting edge 3 of the cutting segment module 2 is flush with the cutting edge 3 of the die holder 1. Similarly, gaps 14 are left between the connecting plate 9 and the cutting edge 3 of the die holder 1, and between the connecting plate 9 and the cutting edge 3 of the cutting segment module 2, to prevent the connecting plate 9 from pressing against the material 15, which would result in incomplete cutting of the material 15.

[0026] like Figure 4 As shown, in this embodiment, the blade module 2 is a U-shaped plate. A first support plate 12 and a second support plate 13 extending along its width are spaced apart within its U-shaped groove. The first support plate 12 and the second support plate 13 serve the same function as the reinforcing rod 5, namely, to increase structural strength and prevent deformation of the blade module 2 when pressed down in this embodiment. Gaps 14 are left between the first support plate 12 and the cutting edge 3 of the blade module 2, and between the second support plate 13 and the cutting edge 3 of the blade module 2, i.e., as shown... Figure 7 As shown, the first support plate 12 and the second support plate 13 are both a certain distance from the surface of the material 15, which is also to prevent the first support plate 12 and the second support plate 13 from pressing against the material 15, resulting in incomplete cutting of the material 15.

[0027] Both the die holder 1 and the die segment module 2 are made of cemented carbide material, which has high hardness and wear resistance.

[0028] When using this embodiment, material 15 is laid on the workbench, and the cutting blade 3 of this embodiment is placed face down on the material 15. Pressing down on this embodiment will achieve cutting, and the cut shape will be the same as the outer contour shape of this embodiment. It should be noted that the shape of this embodiment is made according to the current production requirements. Of course, the outer contour of the blade module 2 and the die holder 1 can also be set to other shapes. When it is necessary to cut workpieces of different sizes, the current blade module 2 can be removed and replaced with a blade module 2 of another length and fixed to the die holder 1. See [link to documentation]. Figure 8 .

[0029] This embodiment achieves flexible and continuous adjustment of the die size by combining different lengths of the blade segment modules 2 with a fixed die holder 1, thus quickly forming a continuous cutting edge of the required total length. Manufacturing enterprises no longer need to purchase an entire die set for every minor dimensional change; they only need to stock a standard die holder 1 and a series of blade segment modules 2 of different lengths. These can be arranged and combined to meet various production needs, significantly reducing the total number of dies and directly lowering the enterprise's equipment purchase and warehousing management costs.

[0030] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
