Description

Technical Field

[0001] This utility model relates to a pressing mold, specifically a pressing mold for producing rubber rollers. Background Technology

[0002] Rubber rollers are widely used in various industrial production processes due to their advantages such as high coefficient of friction, rapid recovery after deformation, and compatibility with chemicals. During the production of rubber rollers, a pressing mold is used to press and shape the outer layer of rubber.

[0003] However, existing rubber roller pressing devices typically only clamp and fix the middle position of the mold. When injecting material into the mold, the two ends are easily unstable and shift, causing material leakage. Therefore, a pressing mold for rubber roller production with clamping and fixing is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as insecure installation and easy material leakage, this utility model provides a pressing mold for producing rubber rollers.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a pressing mold for producing rubber rollers, comprising a support plate, two first sliding grooves on the upper surface of the support plate, support frames at both ends of the upper surface of the support plate, two sliders fixedly connected to the lower surfaces of the two support frames, the outer surfaces of the two sliders being slidably connected to the interior of the two first sliding grooves, a rotating frame rotatably connected to the interior of the support frame, three limiting grooves evenly formed on the outer surface of the rotating frame, a rotating block rotatably connected to the interior of each of the three limiting grooves, a sliding rod slidably connected to the interior of the rotating block, one end of the sliding rod rotatably connected to the inner wall of the support frame, and a pulley rotatably connected to the other end of the sliding rod, a first fixing block fixedly connected to the outer surface of the rotating frame, a first limiting block rotatably connected to one side of the first fixing block, a second limiting block rotatably connected to the inner wall of the support frame, a second transmission threaded rod rotatably connected to the interior of the second limiting block, and the outer surface of the second transmission threaded rod being threadedly connected to the interior of the first limiting block.

[0007] As a preferred embodiment of this utility model, the two support frames are respectively threaded with a first transmission threaded rod, one end of the first transmission threaded rod is fixedly connected to a rotating disk, and the other end of the first transmission threaded rod is fixedly connected to a push plate.

[0008] As a preferred embodiment of this utility model, both of the support frames are internally threaded with a first bidirectional threaded rod, and both ends of the first bidirectional threaded rod penetrate the surfaces of the two support frames. A first motor is fixedly connected to the upper surface of the support plate, and the output end of the first motor is fixedly connected to one end of the first bidirectional threaded rod through a coupling.

[0009] As a preferred embodiment of this utility model, a support block is fixedly connected to the upper surface of the support plate, and a second sliding groove is provided inside the support block.

[0010] As a preferred embodiment of this utility model, the support block is internally rotatably connected to a second bidirectional threaded rod, both ends of which penetrate the surface of the support block. A limiting plate is fixedly connected to the front of the support block, and a second motor is fixedly connected to the upper surface of the limiting plate. The output end of the second motor is fixedly connected to one end of the second bidirectional threaded rod via a coupling.

[0011] As a preferred embodiment of this utility model, one end of the outer surface of the support block is threadedly connected to a first sleeve, and the upper surface of the first sleeve is fixedly connected to a first feed port.

[0012] As a preferred embodiment of this utility model, the other end of the outer surface of the support block is threadedly connected to a second sleeve, and the upper surface of the second sleeve is fixedly connected to a second feed port.

[0013] The beneficial effects of this utility model are as follows: This pressing mold for producing rubber rollers drives the first bidirectional threaded rod to rotate by starting the first motor. Utilizing the threaded transmission between the first bidirectional threaded rod and the support frame, two rotating frames are fitted onto the ends of the first and second sleeves. Then, a tool is used to rotate the second transmission threaded rod, causing it to engage in threaded transmission with the first limiting block. The first fixing block and the second limiting block move closer to each other, and the rotating frame rotates inside the support frame. Under the limiting action of the rotating block, the sliding rod rotates around the connection between the sliding rod and the support frame. At this time, the three sliding rods simultaneously slide inside the rotating block, causing the three pulleys to move towards the center position. The three pulleys apply force to the first and second sleeves, limiting their movement and preventing them from being stretched apart and shifting during the material injection process, thus preventing material leakage.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this utility model discloses a pressing mold for producing rubber rollers, including a support plate 1. Two first sliding grooves 2 are formed on the upper surface of the support plate 1. Support frames 6 are provided at both ends of the upper surface of the support plate 1. Two sliders 3 are fixedly connected to the lower surfaces of the two support frames 6. The outer surfaces of the two sliders 3 are slidably connected to the interior of the two first sliding grooves 2. A rotating frame 10 is rotatably connected inside the support frame 6. Three limiting grooves 15 are evenly formed on the outer surface of the rotating frame 10. Rotating blocks 16 are rotatably connected inside each of the three limiting grooves 15. A sliding rod 17 is slidably connected inside the rotating block 16. One end of the sliding rod 17 is rotatably connected to the inner wall of the support frame 6, and the other end of the sliding rod 17 is rotatably connected to a pulley 18. A first fixing block 11 is fixedly connected to the outer surface of the rotating frame 10. A first limiting block 12 is rotatably connected to one side of the first fixing block 11. A second limiting block 13 is rotatably connected to the inner wall of the support frame 6. A second transmission threaded rod 14 is rotatably connected inside the second limiting block 13. The outer surface of the second transmission threaded rod 14 is slidably connected to the first... The internal threaded connection of the limiting block 12 activates the first motor 7, causing the first bidirectional threaded rod 8 to engage in threaded transmission with the two support frames 6. This causes the two support frames 6 to move towards the center under the limiting action of the first sliding groove 2, allowing the rotating frame 10 to fit onto the outer surfaces of the first sleeve 24 and the second sleeve 25. Then, the second transmission threaded rod 14 is rotated, causing it to engage in threaded transmission with the first limiting block 12. The first fixed block 11 and the second limiting block 13 move closer together, and the rotating frame 10 rotates within the support frame 6. When the movement occurs, all three sliding rods 17 rotate around the connection between the sliding rod 17 and the support frame 6, and slide inside the rotating block 16, causing the pulley 18 to move towards the middle position until the three pulleys 18 contact the first sleeve 24 and the first transmission threaded rod 5, and squeeze the first sleeve 24 and the second sleeve 25, limiting the first sleeve 24 and the second sleeve 25, thus limiting and fixing the first sleeve 24 and the second sleeve 25, and preventing the first sleeve 24 and the second sleeve 25 from shifting and causing material leakage.

[0026] The two support frames 6 are respectively threaded with a first transmission threaded rod 5. One end of the first transmission threaded rod 5 is fixedly connected to a rotating disk 4, and the other end of the first transmission threaded rod 5 is fixedly connected to a push plate 9. The rotating disk 4 is used to rotate the first transmission threaded rod 5.

[0027] Both support frames 6 are internally threaded with a first bidirectional threaded rod 8, and both ends of the first bidirectional threaded rod 8 penetrate the surface of the two support frames 6. A first motor 7 is fixedly connected to the upper surface of the support plate 1. The output end of the first motor 7 is fixedly connected to one end of the first bidirectional threaded rod 8 through a coupling. The first bidirectional threaded rod 8 is used to drive the support frame 6 to move to the middle position.

[0028] Among them, a support block 19 is fixedly connected to the upper surface of the support plate 1. The support block 19 has a second sliding groove 23 inside, which serves to limit the position of the first sleeve 24 and the second sleeve 25.

[0029] The support block 19 is internally rotatably connected to a second bidirectional threaded rod 22, both ends of which penetrate the surface of the support block 19. A limit plate 20 is fixedly connected to the front of the support block 19, and a second motor 21 is fixedly connected to the upper surface of the limit plate 20. The output end of the second motor 21 is fixedly connected to one end of the second bidirectional threaded rod 22 through a coupling. The second motor 21 drives the second bidirectional threaded rod 22 to rotate.

[0030] One end of the outer surface of the support block 19 is threadedly connected to a first sleeve 24, and the upper surface of the first sleeve 24 is fixedly connected to a first feed port 26, which facilitates the injection of materials.

[0031] The other end of the outer surface of the support block 19 is threadedly connected to the second sleeve 25. The upper surface of the second sleeve 25 is fixedly connected to the second feed port 27. The first sleeve 24 and the second sleeve 25 together serve as a shaping roller.

[0032] During operation, the second motor 21 is first started, driving the second bidirectional threaded rod 22 to rotate. The second bidirectional threaded rod 22 then engages with the first sleeve 24 and the second sleeve 25 via threaded transmission, causing them to move towards the center and finally engage. Next, the first motor 7 is started, engaging the first bidirectional threaded rod 8 with the two support frames 6 via threaded transmission, causing them to move towards the center, reaching the ends of the second sleeve 25 and the first sleeve 24. Then, the second transmission threaded rod 14 is rotated, engaging with the first limiting block 12 via threaded transmission, causing the first fixing block 11 and the second limiting block 13 to move closer together. At this time, the rotating frame 10 rotates inside the support frame 6. The movement causes the slide bar 17 to rotate around the connection between the slide bar 17 and the support frame 6, and the slide bar 17 slides inside the rotating block 16. The pulley 18 moves to the middle position until all three pulleys 18 are in contact with the outer surfaces of the first sleeve 24 and the second sleeve 25, limiting and fixing the first sleeve 24 and the second sleeve 25 to prevent them from being stretched apart and shifting during the injection process, causing leakage. Then, the rotating disks 4 at both ends are rotated to make the first transmission threaded rod 5 and the support frame 6 perform threaded transmission. The push plate 9 penetrates between the first sleeve 24 and the second sleeve 25. By adjusting the distance of the push plate 9 penetrating into the second sleeve 25 and the first sleeve 24, the length of the rubber roller is changed.

[0033] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
