Description

Technical Field

[0001] This utility model relates to the field of rubber processing, and in particular to a rubber chip pressing machine with an ejector demolding mechanism. Background Technology

[0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can undergo large deformation under small external forces. After the external force is removed, it can return to its original shape. Rubber is a completely amorphous polymer. In the production process of rubber products, a large amount of rubber debris is often generated. In order to facilitate the recycling of these rubber debris, it is usually necessary to use a tablet press to compress them into blocks.

[0003] However, in existing rubber chip tableting machines, the rubber chips become stuck on the worktable after being pressed and formed, making it difficult for the finished rubber tablets to be ejected from the mold. This not only affects production efficiency but may also damage the mold. To address this issue, we propose a rubber chip tableting machine with an ejection and demolding mechanism. Utility Model Content

[0004] The purpose of this invention is to provide a rubber chip pressing machine with an ejection and demolding mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rubber chip compression machine with an ejection and demolding mechanism includes a support platform. A square base is fixedly connected to the upper surface of the support platform, and a square connecting box is fixedly connected to the back of the square base. A drive motor is fixedly mounted on the upper surface of the square connecting box via a frame. A lead screw is fixedly connected to the output end of the drive motor. A square threaded plate is threaded onto the outer surface of the lead screw. Two square connecting plates are fixedly connected to the outer surface of the square threaded plate. One end of each square connecting plate extends to the outside of the square connecting box, and one end of each square connecting plate is fixedly connected to... There are transmission rods, the front end of each transmission rod passes through the square base and extends to the front of the square base. The front end of each transmission rod is fixedly connected to a horizontal connecting block. The outer surface of each horizontal connecting block is fixedly connected to two vertical plates. The outer surface of each set of vertical plates is fixedly connected to a pusher. The upper surface of the support platform is fixedly connected to a lower mold base. The upper surface of the square base is fixedly connected to a connecting rod. The upper surface of the connecting rod is fixedly connected to a hydraulic cylinder. The output end of the hydraulic cylinder is fixedly connected to a top mold base, and the top mold base matches the lower mold base.

[0007] In a further embodiment, the inner wall of the lower mold base is provided with a groove, and the size of the groove is adapted to the size of the vertical plate and the pusher.

[0008] In a further embodiment, the bottom surface of the support platform is fixedly connected with multiple T-shaped support plates.

[0009] In a further embodiment, the outer surface of the square connecting box is provided with a strip-shaped opening that matches the square connecting plate, and the outer surface of the square stand is provided with two through square openings, and the transmission rod is slidably connected to the through square openings.

[0010] In a further embodiment, two circular sliding columns are fixedly connected to the upper surface of the support platform, and a sliding connecting seat is slidably connected to the outer surface of each circular sliding column. The outer surface of each sliding connecting seat is fixedly connected to the upper surface of the top mold base.

[0011] In a further embodiment, each of the circular sliding columns is fixedly connected to an L-shaped fastener at its top end, and one end of each L-shaped fastener is fixedly connected to the upper surface of the square base.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device provides stable pressure through a hydraulic cylinder, ensuring a tight fit between the top and bottom molds. This guarantees uniform force on the rubber fragments during pressing, improving product quality and consistency. The use of a circular sliding column and sliding connecting seat ensures the stability of the top mold during vertical movement, preventing wobbling that could affect product quality. A drive motor rotates a lead screw, moving the square screw plate and square connecting plate, which in turn moves the transmission rod, horizontal connecting block, vertical plate, and pusher. This allows for rapid ejection of the pressed rubber block from the bottom mold, achieving automatic demolding. The grooves are perfectly matched to the vertical plate and pusher, making the ejection process smoother and preventing jamming. This significantly shortens demolding time, improves production efficiency, avoids damage to the mold caused by manual demolding, and extends mold life. It offers the advantages of more convenient and labor-saving demolding. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5In this utility model, a rubber chip pressing machine with an ejection and demolding mechanism includes a support platform 1. A square base 3 is fixedly connected to the upper surface of the support platform 1. A square connecting box 4 is fixedly connected to the back of the square base 3. A drive motor 10 is fixedly mounted on the upper surface of the square connecting box 4 via a frame. A lead screw 11 is fixedly connected to the output end of the drive motor 10. A square screw plate 12 is threadedly connected to the outer surface of the lead screw 11. Two square connecting plates 13 are fixedly connected to the outer surface of the square screw plate 12. One end of each square connecting plate 13 extends to the outside of the square connecting box 4. A transmission rod 14 is fixedly connected to one end of each square connecting plate 13. The front end of each transmission rod 14 passes through the square base 3 and extends to the front of the square base 3. A horizontal connecting block 15 is fixedly connected to the front end of each transmission rod 14. Two vertical plates 16 are fixedly connected to the outer surface of each horizontal connecting block 15. A pusher 17 is fixedly connected to the outer surface of each set of vertical plates 16. The upper surface of the support platform 1 is fixedly connected to the support platform 1. A lower mold base 8 is fixedly connected, and a connecting rod 5 is fixedly connected to the upper surface of the square upright base 3. A hydraulic cylinder 6 is fixedly connected to the upper surface of the connecting rod 5. The output end of the hydraulic cylinder 6 is fixedly connected to a top mold base 7, and the top mold base 7 matches the lower mold base 8. The hydraulic cylinder 6 provides stable pressure, making the top mold base 7 and the lower mold base 8 fit tightly, ensuring that the rubber fragments are subjected to uniform force during the pressing process, thereby improving the quality and consistency of the product. The drive motor 10 drives the lead screw 11 to rotate, causing the square screw plate 12 and the square connecting plate 13 to move, which in turn drives the transmission rod 14, the horizontal connecting block 15, the vertical plate 16 and the pusher 17 to move. This allows the pressed rubber block to be quickly pushed out of the lower mold base 8, realizing automatic demolding. The groove 9 is adapted to the size of the vertical plate 16 and the pusher 17, making the pushing process smoother and avoiding the impact of material jamming on operation. This greatly shortens the demolding time, improves production efficiency, and avoids the damage to the mold that may be caused by manual demolding.

[0024] The inner wall of the lower mold base 8 is provided with a groove 9, and the size of the groove 9 is adapted to the size of the vertical plate 16 and the pusher 17. This makes the pusher process smoother and avoids the operation being affected by the material jamming. At the same time, after the pusher 17 moves into the groove 9, the lower mold base 8 is flat. The bottom surface of the support platform 1 is fixedly connected with multiple T-shaped support plates 2, making the equipment more stable during use. The outer surface of the square connecting box 4 is provided with a strip opening 19 adapted to the square connecting plate 13. The outer surface of the square stand 3 is provided with two through square openings 18, and the transmission rod 14 is slidably connected to the through square openings 18. During demolding and material pushing, the square connecting plate 13 can slide up and down along the strip openings 19, while the transmission rod 14 moves along the through square openings 18, avoiding jamming during movement, providing accurate guidance, and ensuring the accuracy and stability of the material pushing action.

[0025] Two circular sliding columns 20 are fixedly connected to the upper surface of the support platform 1. Each circular sliding column 20 has a sliding connecting seat 22 slidably connected to its outer surface. The outer surface of each sliding connecting seat 22 is fixedly connected to the upper surface of the top mold base 7. When the top mold base 7 is moved, the base sliding connecting seat 22 can slide on the circular sliding column 20 to improve its movement stability and avoid tilting. Each circular sliding column 20 has an L-shaped fixing member 21 fixedly connected to its top end. One end of each L-shaped fixing member 21 is fixedly connected to the upper surface of the square stand 3. The L-shaped fixing member 21 further enhances the stability of the circular sliding column 20, thereby improving the structural stability of the entire device.

[0026] The working principle of this utility model is as follows:

[0027] When using the equipment, place it securely and connect it to the power supply. Place the rubber scraps in the lower mold base 8, and start the hydraulic cylinder 6 to push the top mold base 7 downward. Utilizing the tight fit between the top mold base 7 and the lower mold base 8, the product can be pressed. After pressing, move the top mold base 7 upward and start the drive motor 10 to rotate the lead screw 11. Under the action of the thread, the lead screw 11 can move up and down with the square screw plate 12. When the square screw plate 12 moves, it moves the horizontal connecting block 15 upward through the square connecting plate 13 and the transmission rod 14. The movement of the horizontal connecting block 15 uses the vertical plate 16 and the pusher 17 to push out the product pressed in the lower mold base 8, making demolding more convenient and easier.
