Description

Technical Field

[0001] This utility model belongs to the technical field of die-cutting equipment, specifically relating to a wooden board die-cutting device. Background Technology

[0002] A wood die-cutting mold is a type of mold used for stamping, cutting, or forming, primarily composed of a wood substrate and embedded blades (or steel wire). Its core function is to cut materials (such as paper, leather, foam, etc.) into specific shapes using pressure (e.g., a hydraulic press, a die-cutting machine). Wood die-cutting molds occupy an important position in packaging, printing, and small-batch production due to their low cost and rapid prototyping advantages. Their core value lies in balancing precision and economic efficiency, making them suitable for flexible production needs.

[0003] However, when die-cutting large-sized products, the cutting line in the wooden die is very close to the edge of the wooden board. When the distance between the cutting line and the edge of the wooden board is too small, due to insufficient edge support material, the wood is prone to micro-cracks or compression deformation under long-term cyclic pressure, which causes the blade fixing strength to gradually decrease. The wooden board cannot guarantee the fixing requirements for a long time. After working for a certain period of time, the blade will loosen. On the one hand, the size will change significantly, affecting product consistency and even leading to batch scrapping. On the other hand, the loose blade may be displaced or fly off during high-speed stamping, posing a risk of mechanical injury and material splashing.

[0004] Based on this, the present invention proposes a wooden board die fixing device to solve the above problems. Summary of the Invention

[0029] This embodiment provides a wooden board die-cutting mold fixing device, including a fixing ring. The fixing ring is disposed around the periphery of the wooden board die-cutting mold and is tightly fitted to the outer surface of the wooden board die-cutting mold. The fixing ring can fix the wooden board die-cutting mold.

[0030] Specifically, the fixing ring can be made of steel. After the existing old wooden die-cutting mold is made, a steel sheet of the same size is used to deform by heating and immediately fixed to the outer periphery of the wooden board. Then, it is cooled and shrunk so that the steel sheet can be in close contact with the wooden board and achieve the effect of fixing, thereby preventing the die-cutting mold from loosening.

[0031] Example 2

[0032] This embodiment provides a wooden board die-cutting device, which differs from Embodiment 1 in that the fixing ring in this embodiment is rectangular in shape and its size is adjustable in the Y-axis direction.

[0033] Specifically, such as Figure 1 As shown, in this embodiment, the fixing ring includes two fixing half-rings 1 and two first screws 5 with the same structure.

[0034] The fixed semicircle 1 includes a first fixing plate 2, two second fixing plates 3, and two first connecting plates 4. The two second fixing plates 3 are respectively fixed vertically to both ends of the first fixing plate 2, and the two second fixing plates 3 are distributed on the same side of the first fixing plate 2. The two first connecting plates 4 are respectively fixedly connected to the ends of the two second fixing plates 3 away from the first fixing plate 2, and the first connecting plates 4 and the second fixing plates 3 are perpendicular to each other.

[0035] Among the four first connecting plates 4 of the two fixed semicircles 1, each pair is in a corresponding position, and each of the four first connecting plates 4 is provided with a threaded hole. That is to say, the two first connecting plates 4 distributed on the same side are parallel to each other, and the threaded holes are in opposite positions.

[0036] Each of the two first screws 5 has two threaded segments with opposite thread directions. One first screw 5 is threadedly connected to two first connecting plates 4 (through threaded holes) on the same side, and the other first screw 5 is threadedly connected to two first connecting plates 4 (through threaded holes) on the other side. When the first screw 5 is rotated, the two fixed half-turns 1 move in a direction that moves closer to or further away from each other.

[0037] In this embodiment, the width of the first fixing plate 2 and the second fixing plate 3 are the same, and the width of the first fixing plate 2 and the second fixing plate 3 is not greater than the thickness of the wooden board die.

[0038] In application, the four first connecting plates 4 are positioned in pairs, and the two first screws 5 are threadedly connected to the first connecting plates 4 on both sides, thus fitting the two fixing half-circles 1 onto the wooden board die. Depending on the length of the wooden board die along the Y-axis, the first screws 5 are screwed on, causing the two fixing half-circles 1 to move closer to or further apart, adjusting the distance between them until the two fixing half-circles 1 completely fix the wooden board die. This embodiment is applicable to wooden board dies of different lengths along the Y-axis, has a wide range of applications, is easy to install and disassemble, can be reused repeatedly, and reduces application costs.

[0039] Example 3

One end of each fixing sub-plate is perpendicularly fixedly connected to the two second fixing plates 3, and the other end of each fixing sub-plate is detachably fixedly connected. In addition, this embodiment also provides two second screws 7, each with two threaded segments having opposite thread directions.

[0042] A second connecting plate 6 is vertically fixed to the end of the fixed sub-plate away from the second fixed plate 3. The second connecting plates 6 of the two fixed sub-plates are distributed on the outer side of the fixed sub-plates and are parallel to each other. The two parallel second connecting plates 6 are provided with threaded holes with corresponding positions. The second screw 7 is threadedly connected to the two second connecting plates 6. When the second screw 7 is rotated, the two fixed sub-plates move in a direction that moves closer to or further away from each other.

[0043] In application, the two second screws 7 are threaded to the second connecting plates 6 on both sides. Depending on the length of the wood cutting die in the X-axis direction, the second screws 7 are tightened, causing the two fixing plates to move closer or further apart until the two fixing half-turns 1 completely fix the wood cutting die. This embodiment is applicable to wood cutting dies with different lengths in the X and Y axes, has a wide range of applications, is easy to install and disassemble, can be reused, and reduces application costs.

[0044] Example 4

[0046] Specifically, such as Figure 3 As shown in this embodiment, each of the two fixed half-circles 1 first fixing plates 2 includes two fixing sub-plates. One end of each of the two fixing sub-plates is perpendicularly fixed to the two second fixing plates 3, and the other end of each of the two fixing sub-plates is detachably fixed.

[0047] The two fixing plates are divided into a first fixing plate and a second fixing plate. The first fixing plate includes an inner plate 8 and an outer plate 9. One end of the inner plate 8 is perpendicularly fixed to the second fixing plate 3, and the other end of the outer plate 9 is fixed to the inner plate 8. The inner surface of the outer plate 9 is in contact with the outer surface of the second fixing plate. The outer plate 9 is provided with threaded holes. The second fixing plate is provided with a plurality of threaded holes. When the threaded holes of the outer plate 9 correspond to the threaded holes of the second fixing plate, they are fixed by inserting bolts and screwing them on.

[0048] The inner plate 8 and the second fixing sub-plate are distributed on the same straight line. The inner plate 8, the outer plate 9 and the second fixing sub-plate all have a certain thickness, and the inner plate 8 and the second fixing sub-plate have the same thickness.

[0049] In application, adjust the distance between the outer plate 9 and the second fixed sub-plate until the two fixed half-turns 1 completely fix the wooden board die. At this time, the threaded hole of the outer plate 9 is aligned with the corresponding threaded hole on the second fixed sub-plate. Insert the bolt and tighten it to fix the device.
