Description

Technical Field

[0001] This invention relates to cable production equipment, and more specifically to a novel coating mold device for high-speed parallel cables. Background Technology

[0002] In conventional high-speed parallel cable wrapping mold devices, the structure mainly consists of a body module, a guide eye mold, and a wrapping forming module. When simultaneously implementing the core wire axial conveying, aluminum foil strip wrapping, and double ground wire winding processes, this device has the following technical limitations: it cannot accurately constrain the radial position of the two ground wires relative to the core wire axis, resulting in uncontrollable radial offset between the center of the ground wire and the center of the core wire; each production initialization requires repeated manual rotation and adjustment of the mold components, significantly extending the production preparation time; inaccurate ground wire position or poor contact will seriously affect the cable's shielding effectiveness and grounding reliability. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned problems and provide a novel coating mold device for high-speed parallel cables. This coating mold device can accurately control the relative position of the core wire and the ground wire, reduce the shaking of the ground wire, not only eliminate the need for frequent mold adjustments, shorten equipment debugging time, and improve production efficiency, but also provide better conveying stability, without significant jumping or scraping off the solder layer.

[0004] The objective of this invention is achieved through the following technical solution: A novel coating mold device for high-speed parallel cables includes a base and an aircraft mold and an eye mold disposed on the base; The model aircraft includes an inlet guide structure, an outlet guide structure, and an aluminum foil guide covering. The inlet guide structure has a core wire inlet guide structure and a ground wire inlet guide structure, with two ground wire inlet guide structures located on both sides of the core wire inlet guide structure. The outlet guide structure includes an integrated outlet clearance structure and a ground wire outlet guide structure, with two ground wire outlet guide structures located on both sides of the integrated outlet clearance structure. One end of the aluminum foil guide covering is an open structure located below the core wire inlet guide structure, and the other end is a closed structure located within the integrated outlet clearance structure. Between the closed structure and the open structure is a gradient covering guide section. The core wire enters from the core wire inlet guide structure and moves downwards towards the aluminum foil, where the gradient covering guide section gradually folds up both sides of the aluminum foil to cover the core wire. The eye mold is fixedly installed at the wire exit end of the aircraft mold.

[0005] In a preferred embodiment of the present invention, the outlet end of the ground wire guide structure is a flat open guide hole. Because existing structures are circular holes, and the outer layer of the ground wire is tin-plated, during the routing process, tin ash will fall off the outer layer of the ground wire and stick to the hole wall, eventually clogging the circular hole structure. Therefore, this solution improves upon the present invention by using a flat open guide hole, allowing the fallen tin ash to drain out from the side, thus preventing clogging.

[0006] In a preferred embodiment of the present invention, the aluminum foil guide cover is provided with curved side wings on both sides along the direction of aluminum foil conveying; the two curved side wings are gradually curved towards the center along the direction of aluminum foil conveying.

[0007] Furthermore, at the exit of the aluminum foil guide cover, one of the bent side wings is bent above the other. This creates a figure-six-shaped exit at the end of the aluminum foil guide cover. The advantages are: First, because traditional aluminum foil guide cover exits are too simple, the transition from the flat surface to the closed surface of the aluminum foil is not smooth enough during high-speed operation, easily generating stress and leading to wrinkles or folds. In contrast, the figure-six-shaped exit of this design provides a continuous, gradual aluminum foil guiding path, rather than a sudden bend, allowing for smoother aluminum foil flow, avoiding stress concentration, and significantly reducing vibration at high speeds. Moreover, by making the aluminum foil guide cover a non-integrated structure, it improves both versatility and flexibility. To adapt to different wire diameters or aluminum foil thicknesses, the aluminum foil guide cover is made into a quickly replaceable component, and the modular design reduces mold changeover time. When switching cable specifications or when the mold wears out, only the aluminum foil guide cover needs to be replaced, resulting in very short downtime. Moreover, only micro-modules need to be manufactured and stocked, rather than the entire aircraft mold, which significantly reduces costs. Furthermore, aluminum foil guide covers of different materials or polishing grades can be equipped for different aluminum foil thicknesses or characteristics.

[0008] Furthermore, the aluminum foil guide cover is made of an ultra-wear-resistant, low-friction coefficient material, such as powder metallurgy steel, ceramic coating, or diamond-like carbon (DLC) coating. This reduces friction and wear, significantly extending the mold's service life under high-speed friction and maintaining profile accuracy; it also reduces the adhesion and friction between the aluminum foil and the mold, making the aluminum foil travel more smoothly and reducing the risk of stringing, scratches, or even breakage; and it has certain anti-static properties, preventing aluminum foil debris from being statically attracted into the mold.

[0009] In a preferred embodiment of the present invention, one end of the aluminum foil guiding and covering component is provided with an inlet section, one end of which is connected to the inlet of the aluminum foil guiding and covering component, and the other end of which extends forward and downward. This helps the aluminum foil to be more smoothly and accurately aligned and enter the guiding and covering area, reducing offset and jitter in the initial inlet stage, providing stable feeding conditions for the subsequent gradient covering process, thereby improving the overall controllability of the covering process and the consistency of the finished product.

[0010] In a preferred embodiment of the present invention, the aircraft model is mounted on a base via an adjustable mounting structure.

[0011] Furthermore, the adjustable mounting structure includes bolts, nuts, and adjustable mounting holes. The adjustable mounting holes are elongated holes and are located on the base. The bolts pass through the aircraft model and the adjustable mounting holes and are fixedly connected to the nuts.

[0012] Compared with the prior art, the present invention has the following advantages: 1. By setting up an aircraft mold with a core wire entry guide structure and a ground wire entry guide structure, the two ground wires can be accurately positioned on both sides of the core wire, effectively constraining the radial position of the ground wire relative to the core wire axis, reducing ground wire sway, eliminating the need for frequent mold adjustments, shortening equipment debugging time, and improving production efficiency.

[0013] 2. The aluminum foil guide covering component adopts a design that transitions from an open structure through a gradually changing covering guide section to a closing structure, making the transition of the aluminum foil from being laid flat to covering the core wire smoother and more continuous. This avoids wrinkles, folding, or breakage caused by stress concentration during high-speed covering, ensuring the tightness and surface flatness of the aluminum foil covering.

[0014] 3. Throughout the process, the relative positions of the core wire and the ground wire remain stable, and the wrapping angle does not fluctuate significantly, avoiding scratching the tin plating layer on the surface of the core wire, which helps to ensure the stability of the electrical performance of the cable.

[0019] To enable those skilled in the art to fully understand the technical solutions of the present invention, the present invention will be further described below in conjunction with embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0020] Example 1 Combination Figures 1-4This embodiment of a novel sheathing mold device for high-speed parallel cables includes a base 1 and an aircraft mold 2 and an eye mold 3 disposed on the base 1. The aircraft mold 2 includes an inlet guide structure, an outlet guide structure, and an aluminum foil guide covering 4. The inlet guide structure is provided with a core wire inlet guide structure 5 and a ground wire inlet guide structure 6. There are two ground wire inlet guide structures 6 located on both sides of the core wire inlet guide structure 5. The outlet guide structure includes an integrated outlet avoidance structure 7 and a ground wire outlet guide structure 8. Two ground wire exit guide structures 8 are provided and located on both sides of the integrated exit avoidance structure 7; one end of the aluminum foil guide covering 4 is an open structure located below the core wire entry guide structure 5, and the other end of the aluminum foil guide covering 4 is a closed structure located in the integrated exit avoidance structure 7. Between the closed structure and the open structure is a gradient covering guide section. The core wire enters from the core wire entry guide structure 5 and moves downwards to adhere to the aluminum foil. The gradient covering guide section gradually folds up both sides of the aluminum foil and covers the core wire. The eye mold 3 is fixedly installed at the exit end of the aircraft mold 2. The specific structure of the eye mold 3 can refer to the prior art.

[0021] Combination Figures 1-4 The outlet end of the ground wire guide structure 8 is a flat open guide hole. Because the existing structure is a round hole, and the outer layer of the ground wire is tin-plated, tin ash will fall off the outer layer of the ground wire and stick to the hole wall during the routing process, eventually clogging the round hole structure. Therefore, this solution improves upon this by using a flat open guide hole, allowing the fallen tin ash to drain out from the side, thus preventing clogging.

[0022] Combination Figures 1-4 Along the direction of aluminum foil conveying, the aluminum foil guide covering 4 is provided with bending side wings 4-1 on both sides; along the direction of aluminum foil conveying, the two bending side wings 4-1 gradually bend towards the center.

[0023] Furthermore, at the outlet of the aluminum foil guide cover 4, one of the bending side wings 4-1 is bent above the other. This creates a figure-six-shaped outlet at the end of the aluminum foil guide cover 4. The advantages are: First, because the outlet of the traditional aluminum foil guide cover 4 is too simple, the transition of the aluminum foil from flat to closed is not smooth enough during high-speed operation, easily generating stress and leading to wrinkles or folds. In contrast, the figure-six-shaped outlet of this design provides a continuous, gradual aluminum foil guiding path, rather than a sudden bend, allowing for smoother aluminum foil flow, avoiding stress concentration, and significantly reducing vibration at high speeds. Moreover, by making the aluminum foil guide cover 4 a non-integral structure, it improves both versatility and flexibility. To adapt to different wire diameters or aluminum foil thicknesses, the aluminum foil guide cover 4 is made into a quickly replaceable component, and the modular design reduces mold change time. When switching cable specifications or when the mold wears out, only the aluminum foil guide cover 4 needs to be replaced, resulting in very short downtime. Moreover, only micro-modules need to be manufactured and stocked, rather than the entire aircraft mold 2, which significantly reduces costs. Furthermore, aluminum foil guide covers 4 can be equipped with different materials or polishing grades to accommodate different aluminum foil thicknesses or characteristics.

[0024] Furthermore, the aluminum foil guide cover 4 is made of an ultra-wear-resistant, low-friction coefficient material, such as powder metallurgy steel, ceramic coating, or diamond-like carbon (DLC) coating. This reduces friction and wear, significantly extending the mold's service life under high-speed friction and maintaining profile accuracy; it also reduces the adhesion and friction between the aluminum foil and the mold, making the aluminum foil travel more smoothly and reducing the risk of stringing, scratches, or even breakage; and it has certain anti-static properties, preventing aluminum foil debris from being attracted to the mold due to static electricity.

[0025] Combination Figures 1-4 The aluminum foil guiding and covering component 4 has an inlet section 4-2 at one end, with one end connected to the inlet of the aluminum foil guiding and covering component 4 and the other end extending forward and downward. This helps the aluminum foil to be more smoothly and accurately aligned and enter the guiding and covering area, reducing the offset and jitter in the initial inlet stage, providing stable feeding conditions for the subsequent gradual covering process, thereby improving the overall controllability of the covering process and the consistency of the finished product.

[0026] Combination Figures 1-4 The aircraft model 2 is mounted on the base 1 via an adjustable mounting structure.

[0027] Furthermore, the adjustable mounting structure includes a bolt 8, a nut, and an adjustable mounting hole 1-1. The adjustable mounting hole 1-1 is an oblong hole and is located on the base 1. The bolt 8 passes through the aircraft model 2 and the adjustable mounting hole 1-1 and is fixedly connected to the nut.

[0028] Example 2 Combination Figures 1-4 The working principle of the novel coating mold device for high-speed parallel cables in this embodiment is as follows: The core wire is input through the core wire guide structure 5 of the aircraft model 2, while the two ground wires are introduced through the ground wire guide structures 6 located on both sides of the core wire. The core wire and the ground wire maintain a relatively fixed radial position within the aircraft model 2, thereby achieving precise positioning of the ground wire relative to the core wire axis and effectively suppressing radial sway and angular jump of the ground wire during high-speed operation. At the same time, the flat aluminum foil strip is introduced from the open structure end of the aluminum foil guide covering part 4, smoothly entering the gradient covering guide section through the front inlet section 4-2. This section has bending side wings 4-1 that gradually bend towards the center on both sides, allowing the aluminum foil strip to gradually curl from a flat state. At the exit end, the bending side wings 4-1 on both sides form a "6"-shaped closing structure, allowing the aluminum foil to complete a smooth and continuous deformation transition before wrapping the core wire, avoiding stress concentration and preventing wrinkles, folds, or breakage.

[0029] Inside the aircraft mold 2, the core wire is placed close to the aluminum foil strip. As the aluminum foil is gathered through the "6"-shaped exit, the two edges of the aluminum foil gradually overlap and wrap around the core wire. At the same time, the two ground wires are precisely guided on both sides of the aluminum foil and then enter the eye mold 3 together. The inner cavity of the eye mold 3 completely closes and compacts the aluminum foil, making the edges of the aluminum foil tightly overlap. Finally, the core wire wrapped by the aluminum foil and the ground wires on both sides come out of the eye mold. Subsequently, the ground wires are wound with the wrapped core wire through other devices.

[0030] The above are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
