Description

Technical Field

[0001] This application relates to the field of cable processing technology, and in particular to a layered composite cable extrusion die. Background Technology

[0002] A layered composite cable extrusion die is a type of die capable of manufacturing multi-layered cables, typically used in the production of electrical cables, fiber optic cables, signal transmission cables, and other similar products. Its main function is to composite and extrude layers of different materials or functions according to a predetermined structure, thereby obtaining multi-functional cables. The core of this die design is to achieve precise control and layered composite of different materials, ensuring that the material in each layer is rationally distributed and processed during the extrusion process.

[0003] However, in the extrusion die used, the die head is installed on the output end of the extruder. During the wire extrusion process, the die outlet is prone to adsorbing dust and raw material residue generated by friction, which affects the extrusion processing of the cable. This is because the outlet is not well protected when not in use, resulting in dust adhesion. In order to avoid this situation and reduce the impact of dust on the cable, a layered composite cable extrusion die was designed to solve the above-mentioned problems. Utility Model Content

[0004] To address this problem, this application provides a layered composite cable extrusion die.

[0005] The layered composite cable extrusion die provided in this application adopts the following technical solution:

[0006] A layered composite cable extrusion die includes an extrusion die body. Mounting rods are fixedly connected to the upper and lower ends of the cable outlet on one side of the extrusion die body. An installation tube is fixedly installed on the side of the mounting rod away from the extrusion die body. The opening of the installation tube is opposite to the mounting rod, and a fixing rod is slidably connected inside the tube. A pressure block is installed on one side of the fixing rod. A protective plate is provided on the side of the pressure block near the extrusion die body. A protective soft block is installed on the side of the protective plate near the extrusion die body. The protective soft block is inserted into the cable outlet of the extrusion die body.

[0007] Preferably, a tension spring is fixedly connected to the side of the fixing rod closest to the inside of the mounting tube, and the tension spring is fixedly connected to the inner wall of the mounting tube on the side furthest from the fixing rod.

[0008] Preferably, a support block is fixedly connected to one side of the pressure block, and a fixing rod end wall is fixedly connected to one side of the support block.

[0009] Preferably, the protective plate has a circular groove, and a rotating rod is rotatably connected in the circular groove. One end of the rotating rod passes through the circular groove and is fixedly connected to the protective soft block.

[0010] Preferably, the upper and lower ends of the rotating rod are fixedly connected to support rods, and the support rods are slidably connected to circular grooves.

[0011] Preferably, one side of the support rod passes through a circular groove and is fixedly connected to a limiting block, the limiting block being arc-shaped.

[0012] Preferably, a limiting groove is provided on the side of the pressure block near the protective plate, and the limiting groove is arc-shaped.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] In this invention, by installing a mounting tube, a tension spring, and a fixing rod structure at the upper and lower ends of the cable outlet of the extrusion die body, the cable outlet of the extrusion die body can be protected by a protective plate and a protective soft block when the extrusion die body is temporarily stopped from use. This prevents dust from adhering to the cable outlet of the extrusion die body, resulting in better cable extrusion processing quality. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0020] This application discloses a layered composite cable extrusion die. (Refer to...) Figure 1-3A layered composite cable extrusion die includes an extrusion die body 1. Mounting rods 2 are fixedly connected to the upper and lower ends of the cable outlet on one side of the extrusion die body 1. An installation tube 3 is fixedly installed on the side of the mounting rod 2 away from the extrusion die body 1. The opening of the installation tube 3 faces away from the mounting rod 2, and a fixing rod 4 is slidably connected inside the tube, allowing the support block 5 and pressure block 6 installed on one side of the fixing rod 4 to be adjustable. The support block 5 is fixedly connected to one side of the fixing rod 4, and a pressure block 6 is fixedly installed on one side of the support block 5. A protective plate 7 is provided on the side of the pressure block 6 near the extrusion die body 1. A protective soft block 8 is installed on the side of the protective plate 7 near the extrusion die body 1. The protective soft block 8 is inserted into the cable outlet of the extrusion die body 1, thereby protecting the cable outlet of the extrusion die body 1.

[0021] By adopting the above technical solution, the side of the fixing rod 4 closest to the inside of the mounting tube 3 is fixedly connected to the tension spring 31, and the side of the tension spring 31 away from the fixing rod 4 is fixedly connected to the inner wall of the mounting tube 3.

[0022] By adopting the above technical solution, a circular groove 71 is provided in the protective plate 7. A rotating rod 81 is rotatably connected in the circular groove 71. One end of the rotating rod 81 passes through the circular groove 71 and is fixedly connected to the protective soft block 8. The upper and lower ends of the rotating rod 81 are fixedly connected to the support rod 91. The support rod 91 is slidably connected to the circular groove 71. One side of the support rod 91 passes through the circular groove 71 and is fixedly connected to the limiting block 9. The limiting block 9 is arc-shaped. A limiting groove 61 is provided on the side of the pressure block 6 near the protective plate 7. The limiting groove 61 is arc-shaped, so that the limiting block 9 can enter the limiting groove 61, thereby connecting the pressure block 6 and the protective plate 7 and supporting the protective plate 7.

[0023] The rotatable rotating rod 81 causes the protective soft block 8 on one side to rotate. The protective soft block 8 rotates and wipes the inside of the extrusion die body 1. At the same time, the rotation of the rotating rod 81 also causes the support rod 91 to rotate, causing the support rod 91 to move the limiting block 9. After the limiting block 9 moves, it separates from the limiting groove 61. Then, the rotating rod 81 is pulled directly, causing the rotating rod 81 to separate the protective soft block 8 from the extrusion die body 1. The protective plate 7 can block the extrusion die body 1, thereby preventing dust from affecting the extrusion die and causing damage to the cable extrusion process.

[0024] The implementation principle of a layered composite cable extrusion die in this application embodiment is as follows: The rotatable rotating rod 81 drives the protective soft block 8 on one side to rotate. The protective soft block 8 rotates and wipes the inside of the extrusion die body 1. At the same time, the rotation of the rotating rod 81 also drives the support rod 91 to rotate, causing the support rod 91 to move the limiting block 9. After the limiting block 9 moves, it separates from the limiting groove 61. Then, the rotating rod 81 is pulled directly, causing the rotating rod 81 to move the protective soft block 8 away from the extrusion die body 1 and push the pressure block 6 to move. The pressure block 6 drives the support block 5 to move, and the support block 5 drives the fixing rod 4 to move, so that the fixing rod 4 protrudes from the mounting tube 3 and pulls the tension spring 31 to extend. Then, the protective plate 7 is pushed horizontally to separate the protective plate 7 from the pressure block 6, so that the protective plate 7 no longer covers the extrusion die body 1. The extrusion die body 1 can then be used for cable extrusion processing. The protective plate 7 can block the extrusion die body 1, thereby preventing dust from affecting the extrusion die and causing cable extrusion processing.

[0025] After use, first pull the two pressure blocks 6 to move the fixing rod 4 again. The fixing rod 4 causes the tension spring 31 to extend, separating the pressure block 6 from the extrusion die body 1. Then move the protective plate 7 so that the protective plate 7 drives the protective soft block 8 into the outlet of the extrusion die body 1. Then release the pressure block 6 so that the tension spring 31 drives the fixing rod 4 to return to its original position and the fixing rod 4 drives the pressure block 6 to squeeze the protective plate 7. Then rotate the rotating rod 81 again so that the rotating rod 81 drives the limiting block 9 to rotate. After the limiting block 9 rotates, it enters the limiting groove 61. This allows the extrusion die body 1 to be continuously protected by the protective plate 7 when not in use.
