Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to an integrated molding device for parallel structural wires. Background Technology

[0002] HDMI cables are widely used digital video and audio interfaces capable of transmitting high-definition video and multi-channel audio data, ensuring the highest quality audio and video signal transmission. The parallel pair structure in HDMI cables helps improve signal transmission efficiency and anti-interference capabilities, especially during high-speed data transmission; for example... Figure 1 The traditional parallel-pair structure of HDMI cables shown typically involves wrapping each cable with an insulation layer, adding a ground wire, and then wrapping the cables with an aluminum foil shielding layer to further isolate them from external electromagnetic interference. Because each cable needs to be insulated and shielded separately, this step-by-step processing method limits the automation level of the production line and affects the overall production efficiency. When the two cables are placed in parallel, displacement may occur between the cables due to external forces or slight differences in the processing, which will affect the consistency of the cables and the stability of the signal.

[0028] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0029] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0031] An embodiment of this utility model provides an integral forming device for parallel structural wires, such as... Figure 1-7 Shown, including:

[0032] At least two sets of wires 1, including a first wire 101 and a second wire 102:

[0033] The conveying assembly 2, used for conveying the wire 1, includes a support base 201 and a first conveying wheel structure 202 disposed on the support base 201;

[0034] The molding component 3 includes a first guiding structure 301 for guiding the wire 1 to gradually approach and parallel, and a molding structure 302 sleeved on the outside of the first guiding structure 301 for integrally molding the outer layer structure of the wire 1. The first guiding structure 301 is provided with a guiding groove 303, and the molding structure 302 is provided with a molding cavity 304 that communicates with the guiding groove 303. The first guiding structure 301 and the molding structure 302 are combined to form an injection cavity 305 that communicates with the molding cavity 304. One side of the molding structure 302 is provided with an injection groove 306 that connects to the injection cavity 305.

[0035] The cooling assembly 4 includes a cooling tank 401 for curing the molding wire 5, a second guide structure 402 disposed on one side of the cooling tank 401 for guiding the molding wire 5 into and out of the cooling tank 401, and a third guide structure 403 disposed in the cooling tank 401 for guiding the molding wire 5 forward.

[0036] Unlike traditional parallel pair structures (such as...) Figure 1 The production method of separately molding and then wrapping the structure shown in the figure, and the parallel structure of this utility model (such as Figure 2The structure shown utilizes a molding assembly 3 to integrally form the outer insulating layer of the wire 1. Specifically, at least two sets of wires 1, namely a first wire 101 and a second wire 102, are prepared. These wires 1 can have the same diameter or different diameters, and the material can be copper wire, aluminum wire, or other suitable conductive materials. Each wire 1 is fed into the molding assembly 3 via a conveying assembly 2. The support base 201 of the conveying assembly 2 is used to fix and support the entire device. A first conveying wheel structure 202 is provided on the support base 201 for conveying the first wire 101 and the second wire 102. This structure can be a single conveying wheel with grooves corresponding to the number of each wire 1, or the first conveying wheel structure 202 can be multiple grooves corresponding to the number of wires 1. A number of synchronously rotating conveyor wheels corresponding to the wire 1 ensure that the wire 1 moves into the forming assembly 3 at the same speed. For better integrated forming, the first guide structure 301 is provided with guide grooves 303 to guide the wire 1 gradually closer together. The two guide grooves 303 move from the inlet to the outlet of the wire, bringing the two wires 1 closer together. This ensures that the wires 1 are aligned to the appropriate distance before entering the forming structure 302, achieving a more compact forming effect. The forming structure 302 is fitted onto the outside of the first guide structure 301. The fitting method can be a transition fit, a snap-fit ​​structure, or other assembly methods. After assembly, there will be a gap between the outer surface of the first guide structure 301 and the inner surface of the forming structure 302. An injection cavity 305 is formed. A molding cavity 304, which communicates with a guide groove 303, is provided on one side of the injection cavity 305. The injection solution, which is actually an insulating material solution, is injected into the injection cavity 305 from an injection groove 306 connected to the injection cavity 305. When the first wire 101 and the second wire 102 exit from the guide groove 303 in the first guide structure 301, they pass through the injection cavity 305 and enter the molding cavity 304. During the pulling process, the injection solution in the injection cavity 305 adheres to the wire 1 and is carried into the molding cavity 304 for integral injection molding. The molded wire 1 enters the cooling tank 401 for cooling through a second guide structure 402. The second guide structure 402 can be a guide hole, guide tube, or guide tube. The device includes a guide plate, drive wheel, conveyor belt, etc. The cooling tank 401 can be water-cooled or air-cooled, depending on the material properties and curing requirements. In practice, water cooling is used to cure the outer layer of the wire 1, which is convenient for reducing costs. The formed wire 1 is guided by the third guide structure 403 to move in the cooling tank 401. Since water cooling is used, the second guide structure 402 is used to guide the wire 1 into the water, and the third guide structure 403 is used to lift the formed wire 5 in the water and continue to transport it forward for cooling. The cooled and cured wire 1 is output from the other end of the cooling tank 401, completing the one-piece molding process. The device has a simple structure, good one-piece molding effect, low production cost, good molding and transmission quality, and high stability.

[0037] In some embodiments, as Figure 5As shown, the molding cavity 304 is provided with a first arc portion 307 that matches the shape of the first wire 101, a second arc portion 308 that matches the second wire 102, a first protrusion 309 that connects the first arc portion 307 and the second arc portion 308, and a second protrusion 310 that connects the first arc portion 307 and the second arc portion 308.

[0038] The first arc portion 307 matches the shape of the first wire 101, and the second arc portion 308 matches the second wire 102, ensuring that each wire 1 can be accurately positioned and wrapped during the forming process. The shape and size of each arc portion are designed according to the diameter of each wire 1. The forming part can also be designed as multiple wires 1 and multiple arc portions. In practice, there are two sets of wires 1. The diameter of the first wire 101 and the second wire 102 is the same. The first arc portion 307 and the second arc portion 308 are symmetrically arranged. The first protrusion 309 connects the first arc portion 307 and the second arc portion 308, and the second protrusion 310 also connects the first arc portion 307 and the second arc portion 308. The design of the protrusion ensures that the wires 1 can be separated and do not contact each other, so that the insulating solution can be filled between each wire 1 to achieve the effect of mutual isolation.

[0039] Furthermore, such as Figure 5 As shown, both the first protrusion 309 and the second protrusion 310 are semi-circular structures.

[0040] The semi-circular design is smoother, making it easier to form and separate wires. The key point is that after forming, the ground wire can be placed in a close fit, which is convenient for subsequent processing and re-coating of the shielding layer. However, it does not improve the appearance of the parallel structure.

[0041] In some embodiments, as Figure 4 As shown, the first guiding structure 301 includes a conical wire exit structure 311 located on the side close to the molding structure 302. The molding structure 302 is provided with an injection groove 312 that matches the wire exit structure 311. The injection cavity 305 is a cavity formed between the outer surface of the wire exit structure 311 and the inner wall of the injection groove 312.

[0042] The diameter of the outlet structure 311 gradually decreases as the guide grooves 303 approach each other. In practice, the side surface of the outlet structure 311 is a conical structure, the outlet part 314 is a flat side, and the injection groove 312 is also a corresponding conical structure. This structure is smooth, easy to process, and facilitates the entry and flow of the injection liquid. The molding structure 302 is sleeved on the outside of the first guide structure 301, but the two are not tightly fitted on the side of the outlet structure 311, but form a cavity. This cavity is the injection cavity 305, which is convenient for injecting the injection liquid and can enter the injection cavity 305 along the arc of the cone.

[0043] In some embodiments, as Figure 4 As shown, the guide groove 303 includes a plurality of inlet sections 313 located on one side of the first guide structure 301 and a plurality of outlet sections 314 located on the other side and docking with the molding cavity 304. The distance between the outlet sections 314 is less than the distance between the inlet sections 313.

[0044] The relatively large distance between the inlet sections 313 makes it easier to enter during transport. The wires 1 are guided by the guide groove 303 and gradually move closer to each other. The forming distance between each wire 1 is determined according to the distance between the outlet sections 314.

[0045] In some embodiments, as Figure 4 As shown, the first guide structure 301 has a first annular groove 315 for fixing on its outer side, and the molding component 3 has a second annular groove 316 for fixing on one side.

[0046] In practice, the molding structure 302 is also provided with an injection molding mechanism and a shell on the outside. The first annular groove 315 can fix the first guide structure 301 on the side corresponding to the conveying component, so that the wire 1 can be smoothly introduced. The second annular groove 316 can snap the molding structure 302 on the side facing the cooling component 4, so that the wire 1 can be smoothly discharged.

[0047] In some embodiments, as Figure 3 , 6 As shown, the second guide structure 402 includes an insert plate structure 404 disposed at the end of the cooling tank 401, a baffle plate 405 inserted into the insert plate structure 404, and a flexible structure 406 inserted into the insert plate structure 404. The baffle plate 405 is provided with an opening groove 407 for the forming wire 5 to pass through.

[0048] The insert structure 404 serves as the base for fixing and supporting other components. It can be inserted into baffles 405 of various structures or other structures to increase the practicality of the cooling tank 401. The baffle 405 is inserted into the insert structure 404 to prevent coolant from overflowing or splashing. The opening groove 407 on the baffle 405 is a channel specifically designed for the forming wire 5. It can be a hole in the middle of the baffle 405 to guide the forming wire 5 into the cooling tank 401, or it can be a U-shaped opening structure. Since there is a certain gap between the opening groove 407 and the forming wire 5, the liquid in the cooling tank 401 may overflow. A flexible structure 406 is provided on one side to cover the forming wire 5 to achieve a leak-proof effect without damaging the external structure of the forming wire 5.

[0049] In some embodiments, as Figure 3 , 6As shown in Figures 7 and 8, the third guide structure 403 includes a second conveying wheel structure 408 disposed in the cooling tank 401 and an up-and-down adjustment structure 409 disposed on both sides of the second conveying wheel structure 408. The second conveying wheel structure 408 has a first conveying groove 410 in the middle for placing the forming wire 5. The up-and-down adjustment structure 409 has multiple adjustment grooves 411 on one side that match the central bearing of the second conveying wheel structure 408.

[0050] The second conveyor wheel structure 408 is disposed in the cooling tank 401 for guiding and conveying the forming wire 5. The second conveyor wheel structure 408 has a first conveying groove 410 in the middle, which is specially designed to place the forming wire 5 to ensure that the wire 1 can be lifted in the water and pass smoothly during the cooling process. The up and down adjustment structure 409 is disposed on both sides of the second conveyor wheel structure 408. The height of the second conveyor wheel structure 408 can be adjusted by adjusting the groove 411 that matches the central bearing of the second conveyor wheel structure 408, thereby accommodating forming wires 5 of different diameters or tensions.

[0051] In some embodiments, as Figure 3 , 6 As shown, the cooling assembly 4 also includes an upper and lower water circulation system 412. The upper and lower water circulation system 412 includes an inlet water pipe 413 and a return water pipe 414 disposed below the cooling tank 401, a lower water pipe structure 415 disposed at the bottom of the cooling tank 401 and connected to the return water pipe 414, an upper water pipe structure 416 disposed on one side of the cooling tank 401 and connected to the inlet water pipe 413, and a water collection structure 417 disposed on one side of the cooling tank 401 and connected to the return water pipe 414.

[0052] The inlet pipe 413 can be connected to a cooling water supply system, such as a cooling pump or cooling tower, to ensure that coolant can continuously flow into the cooling tank 401. The return pipe 414 is used to recover the used cooling water from the cooling tank 401, so that the cooling water can be recooled and recycled. The drain pipe structure 415 is set at the bottom of the cooling tank 401 to collect and drain the water in the tank. The inlet pipe structure 416 guides the cooling water into the cooling tank 401. Multiple drain pipe structures 415 and inlet pipe structures 416 can be set according to the length of the cooling tank 401. The water collection structure 417 is used to collect the cooling water flowing out from one side of the cooling tank 401 and connects to the return pipe 414 for easy recycling.

[0053] In some embodiments, as Figure 3 As shown, the first conveyor wheel structure 202 has multiple second conveyor grooves 203 in the middle, and the support base 201 is a triangular frame set on both sides of the second conveyor wheel structure 408.

[0054] The first conveyor wheel structure 202 has multiple second conveyor grooves 203 in the middle, which can facilitate the uniform feeding of multiple sets of wires 1 into the forming component 3. The triangular frame structure is simple and stable.

[0055] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
