Description

Technical Field

[0001] This utility model belongs to the field of wire and cable technology, specifically relating to a low-smoke halogen-free wire and cable extrusion mold. Background Technology

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information, and realize the conversion of electromagnetic energy. In a broad sense, wires and cables are also simply called cables. In a narrow sense, a cable refers to an insulated cable, which can be defined as: an assembly consisting of one or more insulated cores, and their respective possible covering layers, a total protective layer, and an outer sheath. Cables may also have additional uninsulated conductors. Low-smoke halogen-free is a material classification for wire sheaths in the wire and cable industry. Low-smoke halogen-free wire sheaths are made of thermoplastic or thermosetting materials that produce low smoke emissions when heated and are themselves halogen-free. Some low-smoke halogen-free wires and cables are produced using extrusion equipment. After the extrusion process, low-smoke halogen-free material remains at the bottom of the extrusion die, requiring manual cleaning, which is relatively cumbersome. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides the following technical solution: a low-smoke halogen-free wire and cable extrusion mold, including a working tube 1, a first connecting plate 3 fixedly installed on both sides of the working tube 1, a connecting hole 10 opened on the top of the first connecting plate 3, a sealing ring 4 fixedly connected to the top of the working tube 1, a first connecting tube 2 fixedly installed at the bottom of the working tube 1, a second connecting tube 13 fixedly connected to the bottom of the first connecting tube 2, a third connecting plate 14 fixedly installed on the surface of the second connecting tube 13, a motor 9 fixedly installed on one side of the top of the third connecting plate 14, a rotating shaft 11 provided at the output end of the motor 9, and a cutting blade 12 fixedly installed at the bottom end of the rotating shaft 11.

[0020] In a specific embodiment of this utility model, the top of the working tube 1 is placed at the bottom of the external extrusion equipment, and the external screw is used to pass through the connecting hole 10 to fix the device to the external extrusion equipment. The sealing ring 4 is installed to reduce the gap between the device and the external extrusion equipment and increase the connection. The motor 9 is set to work, so that the rotating shaft 11 drives the cutting blade 12 to rotate, cutting and scraping away the low smoke halogen-free material remaining at the bottom of the second connecting tube 13, ensuring the normal extrusion operation of the device in the future, reducing manual cleaning operations, and improving the convenience of using the device.

[0021] In this embodiment: After the device finishes working, the electric push rod 7 is activated, causing it to extend and move the push plate 15 on the inner wall of the connecting block 5 along with the second connecting plate 8. This loosens the low-smoke halogen-free material adhering to the inner wall of the working pipe 1, making it easier for subsequent operators to clean the device and improving its usability. The limiting plate 6 is installed to limit one side of the second connecting plate 8, reducing the impact of the push plate 15 on the inner wall of the working pipe 1 and extending the service life of the device.

External screws are used to pass through the connecting hole 10 to fix the device to the external extrusion equipment. The sealing ring 4 is installed to reduce the gap between the device and the external extrusion equipment and increase the connection. The motor 9 is set to work, causing the rotating shaft 11 to drive the cutting blade 12 to rotate, cutting and scraping away the low-smoke halogen-free material remaining at the bottom of the second connecting tube 13, ensuring the normal extrusion operation of the device and reducing manual cleaning. After the device finishes working, the electric push rod 7 is set to work, causing the push rod of the electric push rod 7 to extend, moving the push plate 15 on the inner wall of the second connecting plate 8 and the connecting block 5, loosening the low-smoke halogen-free material adhering to the inner wall of the working tube 1, making it easier for subsequent operators to clean the device and improving its practicality. The limiting plate 6 is installed to limit one side of the second connecting plate 8 and reduce the collision of the push plate 15 with the inner wall of the working tube 1. All electrical equipment in this device is powered by an external power supply.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
