Description
Technical Field
[0001] This utility model relates to the field of cable processing technology, and in particular to an extrusion die for cable processing. Background Technology
[0002] Cables are a general term for items such as optical cables and electrical cables. They are electronic devices used to transmit electrical signals, power or data. They consist of one or more insulated wires and are often wrapped in a protective layer.
[0003] In existing technologies, extrusion dies are mostly used for cable processing. Extrusion dies can uniformly extrude and coat the insulation material onto the conductor, and precisely control the thickness of the insulation layer. This type of die uses a continuous extrusion method, which can achieve rapid and efficient coating of the cable insulation layer. However, wires and cables have different models and specifications, and various dies of different specifications need to be prepared for production. However, the replacement and disassembly of dies consume a lot of time and production costs. Furthermore, the cable core does not have a centering adjustment function during processing, which can easily lead to the insulation layer falling off and uneven coating. Therefore, it is necessary to propose an extrusion die for cable processing. Utility Model Content

[0022] Example
[0023] like Figures 1 to 5 As shown, the present invention proposes a tube extrusion mold for cable processing, including a mold plate 1. An inner mold 2 and an outer mold 3 are provided on the front side of the mold plate 1. The mold plate 1 is fixedly connected to the inner mold 2 and the outer mold 3. Movable grooves are provided on both the left and right sides of the mold plate 1. A sliding groove is provided on the side of the two movable grooves that are close to each other. Movable grooves are provided on the bottom surface of the two sliding grooves. A guide rod 4 is provided inside each sliding groove. The guide rod 4 is fixedly installed inside the sliding groove. A slider 5 is slidably provided on the outer ring of the bottom end of each guide rod 4. The movement of the slider 5 can be guided and limited by the guide rod 4. The outer wall of the slider 5 is slidably connected to the inner wall of the sliding groove, so that the slider 5 can always maintain a straight running state. A spring 6 is sleeved on the outer ring of the top end of each guide rod 4. The spring 6 is located inside the sliding groove. The elastic deformation direction of the spring 6 can be guided and limited by the guide rod 4. A connecting block 7 is provided on the side of the two sliders 5 that are far apart from each other. The slider 5 is fixedly connected to the connecting block 7.
[0024] Connecting block 1 7 is slidably connected to movable groove 1 to facilitate the movement of connecting block 1 7. Each of the two connecting blocks 1 7 is provided with a lever 8 on the side away from each other. Connecting block 1 7 and lever 8 are fixedly connected. Each slider 5 is provided with a connecting block 2 9 on its rear side. The rear side of slider 5 is fixedly connected to the front side of connecting block 2 9. Connecting block 2 9 is slidably connected to movable groove 2 to facilitate the movement of connecting block 2 9. Each connecting block 2 9 is provided with a locking block 10 on its rear side. The rear side of connecting block 2 9 is fixedly connected to the front side of locking block 10. The mold plate 1 is provided with an installation plate 11 on its rear side. The mold plate 1 and the installation plate 11 are attached but not fixedly connected. The front side of both the mold plate 1 and the installation plate 11 is provided with a cable core through hole to facilitate the cable core to pass through. The front side of the installation plate 11 is provided with two slots 12. Each slot 12 is provided with a set of limiting strips 13 inside. The limiting strips 13 are fixedly installed inside the slot 12 and are located in the lower half of the slot 12.
[0025] Each locking block 10 is slidably connected to a corresponding locking slot 12, and the rear side of the limiting strip 13 is in contact with the front side of the locking block 10. The limiting strip 13 can limit the locking block 10 and prevent it from detaching from the inside of the locking slot 12. The mounting plate 11 has a mounting groove inside, and a cylinder push rod 14 is provided on the bottom surface of the mounting plate 11. The bottom surface of the mounting plate 11 and the top surface of the cylinder push rod 14 are fixedly connected. The output end of the cylinder push rod 14 extends through into the inside of the mounting groove and is provided with a trapezoidal block 15. The output end of the cylinder push rod 14 is slidably connected to the bottom surface of the mounting plate 11, and the output end of the cylinder push rod 14 is fixedly connected to the bottom surface of the trapezoidal block 15. A connecting rod 16 is provided on the top surface of the trapezoidal block 15, and the top surface of the trapezoidal block 15 is fixedly connected to the bottom surface of the connecting rod 16. Trapezoidal guide blocks 22 are provided on both the front and rear sides of the connecting rod 16, and the front and rear sides of the connecting rod 16 are fixedly connected to the trapezoidal guide blocks 22. Trapezoidal grooves are opened on the inner walls of both the front and rear sides of the mounting groove, and the trapezoidal guide blocks 22 are slidably connected to the trapezoidal grooves.
[0026] The trapezoidal groove guides and limits the movement of the connecting rod 16, ensuring it remains in a straight line. A pulley 17 is fixedly connected to the bottom of the pulley 17 at the top of the connecting rod 16. Two positioning blocks 18 are fixedly installed inside the mounting groove, symmetrically arranged around the connecting rod 16. Each positioning block 18 has a clamping rod 19 rotatably mounted on its outer ring. A pulley 20 is magnetically attached to the trapezoidal block 15 at the bottom of each clamping rod 19. The movement of trapezoidal block 15 can always attract pulley 20 to follow. Each clamping rod 19 is equipped with pulley 3 21 at its top. The output end of the cylinder push rod 14 can drive trapezoidal block 15 to move up and down, thereby driving connecting rod 16 and pulley 17 to move up and down. At the same time, the up and down movement of trapezoidal block 15 can push two pulleys 20 to move closer to or further away from each other, thereby driving two pulleys 3 21 to move closer to or further away from each other. This ensures that the center point of pulley 17 and two pulleys 3 21 is always at the center point of the cable hole, and can be adjusted according to the thickness of the cable.
[0027] In this embodiment, when using this device, if it is necessary to change the inner mold 2 and the outer mold 3 according to processing requirements, the two levers 8 can be moved upwards simultaneously. The movement of the levers 8 can drive the connecting block 1 7 and the spring 6 to move upwards, thereby driving the connecting block 2 9 and the locking block 10 to move upwards. This allows the locking block 10 to move to a position inside the locking groove 12 where there is no limit strip 13 blocking it, and then the locking block 10 can be removed from the inside of the locking groove 12. Then, the mold plate 1 can be removed from the mounting plate 11, and the two locking blocks 10 on the new mold plate 1 can be aligned with the upper half of the locking groove 12, then installed and moved downwards, so that the locking blocks 10 move into the locking groove 12 where there is a limit. The position of the limiter 13 ensures the stability of the connection between the mold plate 1 and the mounting plate 11. During processing, when it is necessary to adjust according to the thickness of the cable core, the cylinder push rod 14 can be operated. The output end of the cylinder push rod 14 can drive the trapezoidal block 15 to move up and down, thereby driving the connecting rod 16 and pulley 17 to move up and down. At the same time, the up and down movement of the trapezoidal block 15 can drive the two pulleys 20 to move closer or further away from each other, thereby driving the two pulleys 21 to move closer or further away from each other. This can change the size of the enclosure formed by pulley 17 and the two pulleys 21, thus making it suitable for cable cores of different sizes and adjusting the cable core to the center position.
[0028] The above-described specific embodiments are merely preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
