Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a mold suitable for punching rubber filaments. Background Technology

[0002] Rubber filaments are an elastic fiber material that has a wide range of applications in industries such as machinery, medical, sports equipment, and home furnishings. The molds suitable for cutting rubber filaments are stamping molds specifically designed to cut rubber filaments. They use a specific tool structure to precisely cut the rubber filaments to meet production needs.

[0003] For example, the patent with publication number CN214163288U (a cutting mold for rubber sealing strips) includes a base, a worktable, a top platform and a cylinder, with the worktable, top platform and cylinder arranged sequentially above the base.

[0004] While the aforementioned existing technology makes it convenient for users to clamp sealing rubber strips of different sizes, it lacks a conveying mechanism, which makes it inconvenient to continuously cut the rubber filaments during the cutting process, resulting in poor practicality. Therefore, there is an urgent need in the market to develop a mold suitable for punching rubber filaments to help people solve the existing problems. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-5 This utility model provides an embodiment of a die suitable for punching rubber filaments, including a lower die 1 and an upper die 2 above the lower die 1. In actual use, the upper die 2 is mounted on a lifting mechanism so that the upper die 2 can move up and down. The lower die 1 has a lower die cavity 101 inside, and a lower pressure roller 5 is rotatably mounted inside the lower die cavity 101. There are two lower pressure rollers 5. A motor 4 is fixedly mounted at the front end of the lower die 1. There are two motors 4. The output end of the motor 4 is fixedly connected to the lower pressure roller 5. The upper die 2 has an upper die cavity 201 inside, and a U-shaped plate 9 is set inside the upper die cavity 201. An upper pressure roller 10 is rotatably mounted inside the U-shaped plate 9. There are two upper pressure rollers 10. The lower pressure roller 5 and the upper pressure roller 10 have the same size and shape. An annular arc groove 1001 is set in the middle of the outer side of the upper pressure roller 10.

[0025] During the filament punching process, the lower pressure roller 5 and the upper pressure roller 10 can clamp and transport the filament, achieving continuous feeding and punching, which greatly improves production efficiency. At the same time, the annular arc groove 1001 on the outer side of the upper pressure roller 10 matches the shape of the filament, ensuring accurate positioning of the filament during transport, preventing deviation, and guaranteeing punching accuracy and product quality. This enables continuous automated processing of the filament, improving the practicality of the mold and production efficiency.

[0026] Furthermore, a lower support platform 6 is provided between the two lower pressure rollers 5, and a lower support platform 7 is provided on one side of the right lower pressure roller 5. Both lower support platforms 6 and 7 are fixedly connected to the lower mold 1. An upper support platform 11 is provided between the two upper pressure rollers 10, and an upper support platform 12 is provided on one side of the right upper pressure roller 10. Both upper support platforms 11 and 12 are fixedly connected to the U-shaped plate 9. Guide arc grooves 20 are provided on the lower end surfaces of upper support platforms 11 and 12, and on the upper end surfaces of lower support platforms 6 and 7.

[0027] By setting the guide arc groove 20, the conveying path of the rubber filament can be guided, ensuring the stability and continuity of the rubber filament during the conveying process.

[0028] Furthermore, a compression spring 8 is fixedly installed above the U-shaped plate 9, and multiple compression springs 8 are provided. The upper end of the compression spring 8 is fixedly connected to the upper mold 2. A limiting cavity 202 is provided inside the upper mold 2 along the upper part of the compression spring 8. A vertical rod 18 is provided inside the compression spring 8. The lower end of the vertical rod 18 is fixedly connected to the U-shaped plate 9. The upper end of the vertical rod 18 slides into the interior of the limiting cavity 202. A limiting plate 19 is fixedly installed above the vertical rod 18.

[0029] By setting the compression spring 8, the U-shaped plate 9 and the upper pressure roller 10 are elastically adjusted when subjected to pressure, which can better adapt to rubber filaments of different diameters or hardnesses, and ensure that the rubber filaments are evenly stressed and stably conveyed during the conveying process. The design of the upright 18 and the limiting plate 19 limits the movement range of the U-shaped plate 9, prevents the U-shaped plate 9 from shaking or deviating during operation, and ensures the stability and reliability of the mold operation.

[0030] Furthermore, a punching mechanism 3 is provided on one side of the upper mold 2. The punching mechanism 3 includes a mounting plate 13, an electric cylinder 14, a lifting plate 15, a cutter 16, and a guide post 17. The mounting plate 13 is fixedly connected to the upper mold 2. The electric cylinder 14 is fixedly installed above the mounting plate 13. The lifting plate 15 is located below the mounting plate 13. The push rod end of the electric cylinder 14 slides through the mounting plate 13 and is fixedly connected to the lifting plate 15. The cutter 16 is fixedly installed on one side below the lifting plate 15. The guide post 17 is located on one side of the electric cylinder 14. The lower end of the guide post 17 slides through the mounting plate 13 and is fixedly connected to the lifting plate 15.

[0031] By setting the punching mechanism 3, the rapid punching of the rubber filament is realized. The electric cylinder 14 drives the lifting plate 15 and the cutter 16 on it to descend quickly and cut the rubber filament. The guide post 17 ensures the stability of the lifting plate 15 during the lifting process.

[0032] Working principle: During use, the upper mold 2 is installed on the external lifting mechanism, allowing it to move up and down, while the lower mold 1 remains stationary. The rubber filament is continuously fed through the clamping and conveying of the lower pressure roller 5 and the upper pressure roller 10. The lower pressure roller 5 is driven by the motor 4, and the upper pressure roller 10 is elastically adjusted by the U-shaped plate 9 and the compression spring 8 to accommodate rubber filaments of different diameters or hardnesses, ensuring uniform force on the rubber filament during conveying. The annular arc groove 1001 on the outer side of the upper pressure roller 10 matches the shape of the rubber filament, further preventing the rubber filament from deviating and ensuring the smoothness and continuity of the conveying. When the rubber filament is conveyed to the punching position, the electric cylinder 14 of the punching mechanism 3 drives the lifting plate 15 and the cutter 16 on it to descend rapidly, completing the cutting operation of the rubber filament. The guide column 17 ensures the stability of the lifting plate 15 during the lifting process, preventing the cutter 16 from deviating or shaking, thereby realizing continuous conveying and punching of the rubber filament and improving production efficiency.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
