A die-cutting round flattening mold Technical Field

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

[0002] Die cutting is a manufacturing process that uses specially processed dies to precisely cut flat materials under mechanical pressure. It is widely used in the cutting and processing of paper products, plastics, rubber, fabrics, thin metal sheets, and leather.

[0003] In existing circular flattening die-cutting processes, the processing accuracy has reached the micron level. This requires a high degree of flatness in the lower mold to avoid incomplete, inaccurate, or uneven cutting, thus preventing any impact on the accuracy of the workpiece's dimensions and shape after processing, protecting the lower tool, improving tool life, and ensuring equipment safety. Therefore, we propose a circular flattening die for die-cutting. Summary of the Invention

[0019] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0020] Referring to Figures 1-5, a die-cutting round flattening mold includes a base plate 1, a support plate 2, a die-cutting blade 7, and a pressure plate 3. The support plate 2 is provided on the upper end surface of the base plate 1, and bolts 8 are distributed on the lower end surface of the support plate 2. The lower ends of the bolts 8 pass through the base plate 1, and each bolt 8 is provided with a threaded nut 9. The base plate 1 and the support plate 2 are fixed by the bolts 8 and the nuts 9. The die-cutting blades 7 are distributed in an equidistant array on the upper end surface of the support plate 2, and the pressure plate 3 is provided above the die-cutting blades 7. The die-cutting material is placed between the die-cutting blades 7 and the pressure plate 3.

[0021] The lower end surface of the base plate 1 is provided with an anti-slip layer, and the lower end surface of the base plate 1 is provided with fixing grooves 5. The lower end of the bolt 8 is set in the fixing groove 5, and the upper end surface of the nut 9 abuts against the top surface of the fixing groove 5. Cardboard or other supports are placed between the base plate 1 and the bearing plate 2 to adjust the overall flatness of the bearing plate 2, and it is fixed by the bolt 8 and the nut 9.

[0022] The pressure plate 3 has longitudinally arranged positioning pins 6 at the four corners of its lower end face, and reinforcing ribs 4 are distributed on the upper end face of the pressure plate 3. The reinforcing ribs 4 are evenly distributed in an array. The pressure plate 3 presses on the die-cutting material to prevent the die-cutting material from moving, which facilitates cutting while maintaining the flatness of the die-cutting material and improving the cutting accuracy. In addition, the reinforcing ribs above the pressure plate 3 can evenly transmit the pressure of the rollers on the mold, so that the die-cutting material is evenly distributed.

[0023] The die-cutting blade 7 has a ring structure, with its lower end connected to the upper surface of the support plate 2, and the cutting edge of the die-cutting blade 7 facing the pressure plate 3.

[0024] The upper surface of the support plate 2 has four corners with positioning holes 10. The positioning holes 10 are matched with positioning pins 6. The lower end of the positioning pin 6 is set in the corresponding positioning hole 10 and is slidably connected with the positioning hole 10. The support plate 2 has through grooves 15 that penetrate the support plate 2. The through grooves 15 are matched with the die-cutting blade 7. The through grooves 15 are set in the annulus of the die-cutting blade 7. Each through groove 15 is provided with a support plate 16. When the support plate 16 is flipped, it pushes out one end of the workpiece pressed into the die-cutting blade 7, which facilitates the collection of the workpiece.

[0025] The support plate 2 has rotating shafts 14 distributed on its side. One end of the rotating shaft 14 passes through the through slots 15 distributed along the axial direction. The rotating shaft 14 is connected to the end of the support plate 16 in the through slot 15. The rotating shaft 14 is provided with an adjusting rod 11 on one end of the support plate 2. One end of the adjusting rod 11 is connected to the end of the rotating shaft 14. The other end of each adjusting rod 11 is provided with a connecting rod 12. One side of the connecting rod 12 is rotatably connected to the adjusting rod 11. The other side of the connecting rod 12 is provided with a handle 13. Pushing or pulling the handle 13 causes the connecting rod 12 to move laterally. The lateral movement of the connecting rod 12 causes the upper end of the adjusting rod 11 to rotate, which in turn causes the rotating shaft 14 to rotate, thereby making the support plate 16 on the rotating shaft 14 stand upright or lie flat.

[0026] The die-cutting circular flattening mold described in this embodiment involves installing a support plate 2 on a base plate 1. During installation, the flatness of the support plate 2 is adjusted using a level. Based on the inspection results, appropriate cardboard or other supports are placed below the lower part of the support plate 2 to adjust its overall flatness. It is then secured with bolts 8 and nuts 9. The die-cutting material is laid flat on the die-cutting blade 7, and a pressure plate 3 is placed on the material to prevent movement. This facilitates cutting while maintaining the flatness of the material, improving cutting accuracy. A positioning pin 6 is also included. Insert the platen 3 into the corresponding positioning hole 10 to maintain its stability. During the die-cutting process, the die moves with the conveyor belt to the bottom of the pressure roller. The reinforcing ribs above the platen 3 can evenly transmit the pressure of the pressure roller on the die, so that the die-cutting material is subjected to uniform force. After the die-cutting is completed, remove the platen 3 and push and pull the handle 13 to drive the connecting rod 12 to move laterally. The lateral movement of the connecting rod 12 causes the upper end of the adjusting rod 11 to rotate, which drives the rotating shaft 14 to rotate, thereby making the support plate 16 on the rotating shaft 14 stand upright. When the support plate 16 flips, it pushes out one end of the workpiece pressed into the die-cutting knife 7, which is convenient for collecting the workpiece.
