Description
Technical Field
[0001] This utility model relates to the technical field of wire processing, specifically a double-core mold for processing parallel wires. 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 referred to as cables. In a narrow sense, cables refer to insulated cables, which can be defined as an assembly consisting of one or more insulated wire cores, and their respective possible covering layers, a total protective layer, and an outer sheath. Each die can only extrude one electronic wire at a time, resulting in very low production efficiency. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a dual-core mold for processing parallel wires.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model discloses a double-core mold for processing parallel wires, including an outer mold body. The outer mold body is provided with a flow divider cone, and the outer mold body is provided with symmetrically arranged flow combiner cones on both sides of the flow divider cone. Each flow combiner cone is connected to the flow divider cone through a flow divider channel. Each of the manifold cones has an extrusion tube communicating with the manifold cone at its front end. An inner mold core is installed on the outer mold body and inserted into each manifold cone. An extrusion cavity is formed between the inner mold core and the inner wall of the manifold cone. An injection inlet tube communicating with the diverter cone is provided on the outer mold body. The inner mold core and the outer mold body are connected by a disassembly mechanism. The inner mold core includes an inner mold body that is inserted into the manifold cone and is coaxial with the manifold cone, and the inner mold body has a wire core channel in the middle that is aligned with the extrusion tube.
[0005] As a preferred technical solution of this utility model, the disassembly mechanism includes a connecting pipe provided at the opening of the confluence cone on the outer mold body, the connecting pipe being provided with an internal thread structure, and the inner mold body being provided with an external thread structure that cooperates with the internal thread structure.
[0006] As a preferred embodiment of this utility model, both the outer mold body and the inner mold core are made of nitrided steel or hard alloy.
[0007] As a preferred embodiment of this utility model, the internal shape of the diverter cone is arranged in a mirror-symmetrical manner.
[0008] As a preferred embodiment of this utility model, the injection inlet pipe is disposed on the outer mold body and located at the center of the flow divider cone.
[0009] As a preferred embodiment of this utility model, the end of the core channel is provided with a trumpet-shaped guide portion.
[0010] The beneficial effects of this utility model are: 1. This type of dual-core die for parallel wire processing includes a flow divider cone on the outer die body, and symmetrically arranged converging cones on both sides of the flow divider cone. Each converging cone has an extrusion tube connected to its front end. An inner die core is located within each converging cone. The wire core is inserted into the wire core channel within the inner die body, extends into the converging cone, and then passes through the extrusion tube. The molten insulating plastic is shaped and wrapped around the wire core by the extrusion tube to form an insulating layer. The internal shape of the flow divider cone is mirror-symmetrical, ensuring that the molten plastic flows evenly to the two converging cones, resulting in consistent pressure and ensuring identical extrusion parameters for both wire cores. This allows one extruder to simultaneously extrude two wire cores, thereby improving work efficiency.
[0011] 2. The inner core and outer mold body of this type of double-core mold for parallel wire processing are composed of a threaded structure and an external thread structure with threaded fit, which facilitates installation and disassembly and makes it convenient to inspect the inner core and outer mold body.

[0014] 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.
[0015] Example: Figure 1 , Figure 2 , Figure 3 As shown, this utility model discloses a dual-core mold for processing parallel wires, comprising an outer mold body 1, on which a flow-dividing cone 2 is provided. The outer mold body 1 has symmetrically arranged converging cones 3 on both sides of the flow-dividing cone 2, and each converging cone 3 is connected to the flow-dividing cone 2 via a flow-dividing channel 9. The internal shape of the flow-dividing cone 2 is mirror-symmetrically arranged, so that the molten plastic in the flow-dividing cone 2 flows evenly to the two converging cones 3, making the pressure of the two converging cones 3 consistent, ensuring that the extrusion of the two wire cores is the same, and ensuring that the extrusion parameters of the two wire cores are the same. This allows one extruder to extrude two wire cores simultaneously, thereby improving work efficiency.
[0016] Each of the confluence cones 3 has an extrusion tube 11 at its front end that communicates with the confluence cone 3. An inner mold core 4 is installed on the outer mold body 1 and inserted into each confluence cone 3. An extrusion cavity is formed between the inner mold core and the inner wall of the confluence cone 3. An injection inlet tube 5 that communicates with the diverter cone 2 is provided on the outer mold body 1. The inner mold core 4 is connected to the outer mold body 1 via a disassembly mechanism. The inner mold core 4 includes an inner mold body 401 that is inserted into the confluence cone 3 and is coaxial with the confluence cone 3. A wire core channel 402 that is aligned with the extrusion tube 11 is provided in the middle of the inner mold body 401.
[0017] This invention features a flow divider cone 2 on an outer mold body 1. The outer mold body 1 has symmetrically arranged converging cones 3 on both sides of the flow divider cone 2. Each converging cone 3 has an extrusion tube connected to its front end. Each converging cone 3 contains an inner mold core 4, in which the wire core is inserted from the wire core channel 402 within the inner mold body 401 and extends into the converging cone 3. Then, it passes through the extrusion tube. In this way, the molten insulating plastic is shaped and wrapped around the wire core by the extrusion tube to form an insulating layer. The internal shape of the flow divider cone 2 is mirror-symmetrically arranged, so that the molten plastic in the flow divider cone 2 flows evenly to the two converging cones 3, making the pressure of the two converging cones 3 consistent and ensuring that the extrusion of the two wire cores is the same.
[0018] The disassembly mechanism includes a connecting pipe 6 provided at the opening of the confluence cone 3 on the outer mold body 1, an internal thread structure 7 provided at the connecting pipe 6, and an external thread structure 8 provided on the inner mold body 401 that cooperates with the internal thread structure 7. The inner mold core 4 and the outer mold body 1 are composed of a threaded structure and an external thread structure 8, which facilitates installation and disassembly and makes it convenient to inspect the inner mold core 4 and the outer mold body 1.
[0019] The outer mold body 1 and the inner mold core 4 are both made of nitrided steel or hard alloy, which have good corrosion resistance and a long service life.
[0020] The internal shape of the diverting cone 2 is mirror-symmetrical, which allows the molten plastic in the diverting cone 2 to flow evenly to the two confluence cones 3, making the pressure of the two confluence cones 3 consistent and ensuring that the extrusion of the two wire cores is the same.
[0021] The injection inlet pipe 5 is located on the outer mold body 1 and at the center of the diversion cone 2. This allows the molten plastic in the diversion cone 2 to flow evenly to the two confluence cones 3, ensuring that the pressure in the two confluence cones 3 is consistent and guaranteeing that the extrusion of the two wire cores is identical. The end of the core channel 402 is provided with a trumpet-shaped guide portion 10, which facilitates the threading of the core.
[0022] During operation, this type of dual-core die for parallel wire processing has a flow divider cone 2 on the outer die body 1. The outer die body 1 has symmetrically arranged converging cones 3 on both sides of the flow divider cone 2, and each converging cone 3 has an extrusion tube connected to the front end of the converging cone 3. The inner die core 4 is located in each converging cone 3. The wire core is inserted from the wire core channel 402 in the inner die body 401 and extends into the converging cone 3. Then it passes through the extrusion tube. In this way, the molten insulating plastic is shaped and wrapped around the wire core by the extrusion tube to form an insulating layer. The internal shape of the flow divider cone 2 is mirror-symmetrically arranged, so the molten plastic in the flow divider cone 2 flows evenly to the two converging cones 3, making the pressure of the two converging cones 3 consistent. This ensures that the extrusion of the two wire cores is the same and that the extrusion parameters of the two wire cores are the same. This allows one extruder to extrude two wire cores at the same time, thereby improving work efficiency.
[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. 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
