[0037] Embodiment 1:

[0038] During the die-cutting process, the die needs to be assembled on the equipment and debugged. After the debugging is completed, the substrate to be die-cut is placed on the die and a protective film is laid on it. After the equipment is pressed up and down, the die blade cuts the substrate and the protective film on top is stressed to cut the substrate, thus obtaining the desired product. Currently, since the substrate is placed on the die, it is impossible to ensure that the substrate is cut flatly, resulting in wrinkles on the molded product, product abnormalities, or inaccurate dimensions.

[0039] In order to solve the above problems, combined Figure 1 As shown, this embodiment provides a die-cutting die, which includes a bottom plate 1, a die cutter assembly, and a pressing assembly. The substrate 100 to be die-cut is placed and limited on the bottom plate 1, the die cutter assembly is located above the bottom plate 1, the die cutter assembly includes a die cutter body 2 and a die-cutting tool 3, the die-cutting tool 3 is arranged on the side of the die cutter body 2 facing the bottom plate 1, the die cutter body 2 approaches or moves away from the substrate 100 in the vertical direction, and the pressing assembly is elastically arranged on the side of the die cutter body 2 facing the bottom plate 1. When the die cutter 3 moves away from the substrate 100, the pressing assembly is closer to the bottom plate 1 relative to the die cutter body 2. When the die cutter body 2 die-cuts the substrate 100, the pressing assembly elastically presses the substrate 100.

[0040] It can be understood that by adding a pressing component to the side of the cutting die body 2 facing the base plate 1, when the cutting die assembly descends, the pressing component will first press the substrate 100 placed on the base plate 1 flat against the surface of the base plate 1. As the cutting die assembly continues to descend, the pressing component is elastically compressed, and the die-cutting tool 3 performs die-cutting on the substrate 100. The pressure of the pressing component avoids the movement of the substrate 100 during die-cutting, ensures the reliability of die-cutting, and makes the molded product have good flatness and high dimensional accuracy.

[0041] The die-cutting die of this embodiment is installed in a die-cutting machine, which includes an upper plate (not shown in the figure) and a lower plate (not shown in the figure) arranged up and down, the upper plate is located above the lower plate, and the upper plate is moved in a vertical direction by a driving mechanism to approach or move away from the lower plate. The die-cutting die assembly is connected to the upper plate, and the bottom plate 1 is connected to the lower plate. By die-cutting products of different models or specifications, the die-cutting die can be adaptively replaced.

[0042] like Figure 1 As shown, the pressing assembly of this embodiment includes a connecting member, a pressing plate 43 and an elastic member. A groove 21 is provided on one side of the die-cutting tool 3 facing the bottom plate 1, and a through hole 22 penetrating the die-cutting tool 3 is provided on the bottom wall of the groove 21. One end of the connecting member is slidably inserted into the through hole 22, and the pressing plate 43 is vertically fixed to the other end of the connecting member. The pressing plate 43 is movably embedded in the groove 21, and the elastic member is provided between the bottom wall of the groove 21 and the end face of the pressing plate 43. In addition, the sum of the depth of the groove 21 and the height of the die-cutting tool 3 minus the thickness of the substrate 100 is greater than the thickness of the pressing plate 43, so as to ensure that the setting of the pressing plate 43 does not affect the die-cutting of the substrate 100 by the die-cutting tool 3. When the die-cutting tool 3 is away from the substrate 100, the pressure plate 43 is closer to the bottom plate 1 relative to the die-cutting tool 3, and the driving mechanism drives the die cutter body 2 to descend. The surface of the pressure plate 43 presses on the substrate 100, thereby flattening the substrate 100 on the bottom plate 1. The die cutter body 2 continues to descend to squeeze the elastic member to contract, and the pressure plate 43 extends into the groove 21 until the die-cutting tool 3 contacts the substrate 100 and die-cuts the substrate 100. Through the continuous pressure of the pressure plate 43, the position of the substrate 100 remains unchanged, which makes the die-cutting reliability higher and the size of the molded product more standard.

[0043] In addition, the shape of the groove 21 can match the shape and size of the pressing plate 43, or the shape can be different and the size can be larger than the pressing plate 43. This embodiment does not limit this, and any shape that can achieve the embedding of the pressing plate 43 is sufficient.

[0044] Specifically, the elastic member of this embodiment is a spring 41, and the spring 41 is sleeved on the peripheral side of the connecting member, so that the spring 41 can be extended and retracted along the axial direction of the connecting member, which has a guiding effect, reduces the possibility of deformation of the spring 41, has a longer service life, and is easy to prepare. In addition, one end of the spring 41 abuts against the bottom wall of the groove 21, and the other end of the spring 41 abuts against the surface of the pressure plate 43. In other embodiments, the elastic member can also be a torsion spring, a tension spring, etc.

[0045] The connecting member of the present embodiment is a bolt 42, the head of the bolt 42 is slidably adapted in the through hole 22, and the rod of the bolt 42 is threadedly connected to the pressure plate 43. The bolt 42 is a hexagon socket bolt, and the shape of the through hole 22 also matches the head of the bolt 42, ensuring that the bolt 42 only moves in the through hole 22 in the vertical direction, and has good stability. Further, in order to make the elastic force uniform, a plurality of connecting members are provided, and each connecting member is provided with an elastic member. In the present embodiment, two connecting members are provided, and the two bolts 42 are symmetrically arranged along the central axis of the die body 2. In addition, the pressing force of the pressure plate 43 on the substrate 100 can be adjusted by adjusting the depth of the rod of the bolt 42 screwed into the pressure plate 43, and the controllability is good.

[0046] In addition, when the die-cutting assembly is naturally suspended (the die-cutting tool 3 is away from the substrate 100), the distance between the end face of the head of the bolt 42 that is away from the rod and the upper end face of the upper mold plate is greater than the distance between the side of the pressing plate 43 that faces the bottom plate 1 and the cutting edge of the die-cutting tool 3. This prevents the head of the bolt 42 from interfering with the upper mold plate when the die-cutting assembly is die-cutting the substrate 100, and ensures that the addition of the pressing assembly does not affect the stable operation of the die-cutting mold.

[0047] It should be noted that the friction force between the head of the bolt 42 and the through hole 22 is sufficient to suspend the pressing plate 43 on the die body 2 .

[0048] The pressing plate 43 of this embodiment is made of metal, plastic or other materials. Preferably, the pressing plate 43 is an acrylic plate, which has excellent rigidity and strength, and can provide a strong pressing force to the substrate 100. The pressing plate 43 made of acrylic plate is light, so that the pressing plate 43 can be connected to the die body 2 only by the friction between the bolt 42 and the through hole 22. Of course, the pressing plate 43 can also be a plate of other materials, and this embodiment does not limit the material.

[0049] Optionally, the upper surface of the bottom plate 1 is detachably connected with a wear-resistant plate 11 by bolts 42, and the substrate 100 is laid flat on the wear-resistant plate 11. For example, the wear-resistant plate 11 is a PS plate. The wear-resistant plate 11 protects the bottom plate 1 and prevents the die-cutting tool 3 from wearing the bottom plate 1.

[0050] Now combine Figure 1 The die-cutting process of the die-cutting mold is further described in detail:

[0051] First, the wear-resistant plate 11 is laid in the positioning area of ​​the bottom plate 1, and the wear-resistant plate 11 is fixed by bolts 42;

[0052] Secondly, lay the substrate 100 flat on the wear-resistant plate 11;

[0053] Then, buckle the knife die body 2 downward onto the substrate 100 and check whether the substrate 100 is flat;

[0054] Finally, the die-cutting machine is started, and the upper mold plate moves downward in the vertical direction. The pressure plate 43 first applies a stress to the substrate 100 to flatten the substrate 100. As the stress increases, the spring 41 contracts, and the die-cutting tool 3 impacts the substrate 100 to die-cut the product.

[0055] Embodiment 2:

[0056] This embodiment provides a die-cutting mold. The difference between the die-cutting mold in this embodiment and the die-cutting mold in the first embodiment is that Figure 2As shown, the pressing component of this embodiment includes a knife pad cotton 401, which is arranged on a side of the knife die body 2 facing the bottom plate 1, and the knife pad cotton 401 is coated on the outer periphery of the die cutting tool 3.

[0057] The knife pad cotton 401 is a soft compressible material. In the normal state (the die-cutting tool 3 is far away from the substrate 100), the thickness of the knife pad cotton 401 is greater than the length of the die-cutting tool 3; in the extrusion state (the die die body 2 is die-cutting the substrate 100), the thickness of the knife pad cotton 401 is less than the length of the die-cutting tool 3. When the die-cutting tool 3 is far away from the substrate 100, the knife pad cotton 401 is closer to the bottom plate 1 relative to the die-cutting tool 3, and the driving mechanism drives the die die body 2 to descend, and the surface of the knife pad cotton 401 is pressed against the substrate 100, thereby flattening the substrate 100 on the bottom plate 1. The die die body 2 continues to descend to squeeze the knife pad cotton 401 to shrink until the die-cutting tool 3 contacts the substrate 100 and performs die-cutting on the substrate 100. Through the continuous pressing of the knife pad cotton 401, the position of the substrate 100 remains unchanged, so that the reliability of die-cutting is higher and the size of the molded product is more standardized.

[0058] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
