[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0017] like Figure 1-5 The figure shown is a three-dimensional structural diagram of a single-head injection molding device for a data cable provided in an embodiment of the present utility model, including: a base 1, a rotary worktable 2, and a drive assembly 3; The base 1 is configured as a disc, and an injection mold is arranged circumferentially around the top surface of the disc. The rotating worktable 2 is configured as a ring and is located inside the injection mold on the top surface of the disc. An auxiliary wheel 24 for supporting the rotating worktable 2 is provided between the rotating worktable 2 and the base 1. A carrier 4 is provided on the rotating worktable 2. The rotating worktable 2 rotates under the drive of the drive component 3 to transport the carrier 4 to the injection mold. The drive assembly 3 includes a motor and a gear; the motor is fixed relative to the base 1, the gear is mounted on the output shaft of the motor, and the gear meshes with a gear ring 25 disposed on the rotary table 2 to drive the rotary table 2 to rotate.

[0018] In this embodiment of the invention, by setting the injection mold on the outer periphery of the top surface of the disc, the space of the base 1 facilitates the accurate transport of the carrier 4 to the injection mold by the rotating worktable 2. The auxiliary wheel 24 not only supports the rotating worktable 2 but also reduces friction during rotation. The carrier 4 is used to hold the data cable to be injected. Its reasonable placement on the rotating worktable 2 ensures the stability of the data cable during transport, preventing shaking or deviation that could affect the injection molding effect. The motor, as the power source of the drive component 3, provides stable and controllable power for the rotation of the rotating worktable 2. Through the meshing of the gear with the gear ring 25 on the rotating worktable 2, the rotation speed and angle of the rotating worktable 2 can be controlled, thereby realizing the transport of the carrier 4 between the injection molds.

[0019] In one embodiment of this utility model, multiple processes are integrated into a circular space by the layout of the rotating worktable 2 and the peripheral fixed mold 62. The rotating worktable 2 is used for workstation switching, which saves the time for loading and unloading individual products and opening and closing molds. It is suitable for standard parts such as data cables that require mass production, and effectively improves the space utilization and production efficiency of the equipment.

[0020] The present invention provides a rotating mechanism and device for data cable injection molding. By setting the rotating worktable 2 inside the injection mold, the overall volume is effectively reduced, and the rotating worktable 2 is supported by auxiliary wheels 24 to avoid shaking and sinking caused by long-term use, thereby improving the stability of data cable injection molding production.

[0021] like Figure 3-4 As shown, in a preferred embodiment of the present invention, multiple auxiliary wheels 24 are provided, and the multiple auxiliary wheels 24 are evenly distributed along the circumferential direction of the base 1; the auxiliary wheels 24 are mounted on the base 1 through a rotating shaft; the auxiliary wheels 24 are provided with an annular groove with a V-shaped cross-section along the axial direction, and the bottom periphery of the rotating worktable 2 is embedded in the annular groove to limit the position of the rotating worktable 2 in the horizontal direction.

[0022] In this embodiment of the invention, the auxiliary wheels 24 are evenly distributed along the circumference of the base 1, and each auxiliary wheel 24 is mounted on the base 1 via a pivot, providing full-circumferential support for the rotary table 2. This transforms the sliding friction between the rotary table 2 and the base 1 into the rolling friction of the auxiliary wheels 24 themselves, reducing rotational resistance and making the drive more effortless.

[0023] The V-shaped annular groove design of the auxiliary wheel 24 effectively prevents the rotary table 2 from shifting during operation. Through the V-shaped annular groove structure, the rotary table 2 maintains precise positioning and smooth rotation even when operating at high speeds or bearing heavy loads.

[0024] like Figure 4 As shown, in a preferred embodiment of the present invention, the rotary worktable 2 is composed of a positioning ring 21, a connecting ring 22 and a mounting ring 23; The positioning ring 21 is located at the bottom, and its edge contacts the auxiliary wheel 24. The auxiliary wheel 24 provides radial support for the positioning ring 21, so that the positioning ring 21 does not contact the surface of the base 1. The connecting ring 22 is installed on the top of the positioning ring 21 and is used to connect the positioning ring 21 and the mounting ring 23; the toothed ring 25 is provided on the periphery of the connecting ring 22, and the connecting ring 22 and the toothed ring 25 are subjected to an interference fit. The mounting ring 23 is mounted on the top of the connecting ring 22 and is used to mount the carrier 4; the mounting ring 23 is detachably connected to the positioning ring 21 and the connecting ring 22.

[0025] In this embodiment of the utility model, the rotary worktable 2 includes a positioning ring 21, a connecting ring 22, and a mounting ring 23, which are detachably connected. As the basic component of the rotary table 2, the positioning ring 21 has its outer edge in rolling contact with multiple auxiliary wheels 24 provided on the base 1. The radial support provided by the auxiliary wheels 24 lifts the entire positioning ring 21 into the air, so that the lower surface of the positioning ring 21 is in a non-contact state with the upper surface of the base 1; this reduces the frictional resistance during rotation and avoids wear between the positioning ring 21 and the surface of the base 1.

[0026] The connecting ring 22 is coaxially mounted on the top of the positioning ring 21, connecting the positioning ring 21 with the mounting ring 23 above it. A toothed ring 25 is fitted around the connecting ring 22. The toothed ring 25 is fixed to the connecting ring 22 with an interference fit, ensuring the reliability and synchronicity of power transmission during the transmission process and preventing relative slippage between the two.

[0027] Mounting ring 23 is coaxially mounted on top of connecting ring 22, forming the uppermost working surface of rotary table 2. Its top surface is used to mount and fix carrier 4 to support workpieces to be processed or handled.

[0028] The mounting ring 23, connecting ring 22, and positioning ring 21 are all detachably connected, for example, by circumferentially arranged bolts. This allows the mounting ring 23 to be replaced according to different carrier requirements, and also facilitates individual maintenance, inspection, or replacement of the toothed ring 25 on the connecting ring 22 or the bottom auxiliary wheel 24 support system.

[0029] like Figure 5 As shown, in a preferred embodiment of the present invention, multiple sets of carriers 4 are evenly arranged along the circumference of the rotary worktable 2; the carriers 4 are mounted on the top of the rotary worktable 2 through an ejection mechanism 41 and are used to place data cables; the carriers 4 include a positioning component 42 and a cable fixing component 43. The positioning component 42 is disposed on the top of the ejection mechanism 41. The positioning component 42 is elongated and has multiple interfaces on its side for inserting the metal end of the data cable, which are used to achieve the initial positioning of the metal end of the data cable. The cable fixing assembly 43 includes a fixing frame 431 and a fixing plate 432; the fixing frame 431 is installed on the interface end of the positioning assembly 42 and is used to support the data cable part; the fixing plate 432 is installed above the fixing frame 431 and is fixedly connected to the injection molding assembly 6 by bolts, and the fixing plate 432 is used to further constrain the data cable.

[0030] In this embodiment of the invention, multiple sets of carriers 4 are evenly arranged along the circumference of the top of the rotary worktable 2. These carriers 4 rotate intermittently with the worktable, thereby enabling batch processing of data cables. The carriers 4 are mounted on the top of the rotary worktable 2 via an ejection mechanism 41, which drives the carriers 4 to move vertically. The carrier 4 is composed of a positioning component 42 and a cable fixing component 43. The positioning component 42 is located at the top of the output end of the ejection mechanism 41 and has an overall elongated structure. Multiple interfaces are provided on one side of the positioning component 42. The shape and size of these interfaces match the metal ends of the data cables to be processed. During operation, the metal ends of the data cables are inserted into the corresponding interfaces in sequence to achieve preliminary positioning of the metal ends of multiple data cables, ensuring their accurate position on the horizontal plane. The cable fixing component 43 is used to fix the cable portion of the data cables to prevent them from shaking or shifting in subsequent processes. The cable securing assembly 43 includes a mounting bracket 431 and a mounting plate 432. The mounting bracket 431 is installed at the end of the positioning assembly 42 with an interface, and is used to support the data cable portion extending from the metal end, providing a stable support surface for the cable. The mounting plate 432 is located above the mounting bracket 431, and can be pressed downwards to form a clamping space together with the mounting bracket 431, firmly restraining the data cable portion placed within it. This design provides further securing of the cable, and the cable can be easily removed and placed by loosening the bolts.

[0031] like Figure 5 As shown, in a preferred embodiment of the present invention, the fixing frame 431 and the fixing plate 432 are provided with a plurality of V-shaped slots adapted to the data cable along the interface direction of the positioning component 42.

[0032] In this embodiment of the invention, to ensure that multiple data cables are independent, neatly arranged, and not easily slipped after being fixed, multiple V-shaped slots are formed on the top surface of the fixing frame 431 and the bottom surface of the fixing plate 432 along the arrangement direction of multiple interfaces on the positioning component 42. These V-shaped slots correspond one-to-one with the interfaces on the side of the positioning component 42. Each interface is used to position the metal end of a data cable, and the upper and lower V-shaped slots on the fixing frame 431 and the fixing plate 432 corresponding to it form a channel for clamping the data cable. The shape of the V-shaped slots is adapted to the height of the outer contour of the cylindrical data cable. When the cable is placed in the V-shaped slot of the fixing frame 431 and pressed by the fixing plate 432 with the corresponding V-shaped slots, the V-shaped slope can provide uniform constraint force from both sides or all around the cable. This method has better anti-rolling and anti-slip effects than a simple flat pressure plate and can effectively limit the horizontal displacement of the cable.

[0033] like Figure 5As shown, in a preferred embodiment of the present invention, the ejection mechanism 41 includes a base 1, a movable rod, and a spring; The base 1 is fixedly installed on the top of the rotary worktable 2, and the movable rod is slidably installed on the base 1, with its top fixedly connected to the carrier 4; one end of the spring is connected to the bottom of the movable rod, and the other end abuts against the bottom of the base 1 to provide elastic support for the movable rod.

[0034] In this embodiment of the invention, the ejection mechanism 41 is an elastic lifting device, mainly composed of a base 1, a movable rod, and a spring. The base 1 is fixedly installed on the top of the rotary worktable 2 by bolts or other fastening methods. The movable rod is slidably installed inside the base 1, and its movement trajectory is vertical lifting. The top of the movable rod is fixedly connected to the bottom of the positioning component 42 of the carrier 4, thereby directly driving the entire carrier 4 to move up and down. The spring is installed inside the base 1. There can be one or more springs, one end of which is connected to or abuts against the bottom of the movable rod, and the other end abuts against the bottom inner wall of the base 1. In its natural state, the elastic force of the spring acts upward on the movable rod, providing stable elastic support for the movable rod and the carrier 4 it carries, keeping it in the default raised state.

[0035] In one embodiment of this invention, when the carrier 4 rotates to the station where injection molding is required, an external actuator may apply a downward force to overcome the spring force, pressing the movable rod and the carrier 4 together onto the mold surface. After the operation is completed, the external force is removed, and the spring's restoring force immediately pushes the movable rod and carrier 4 back to their original ejection height, ensuring that the carrier 4 does not interfere with the table or other structures during its rotation to the next station.

[0036] like Figure 1-2 As shown in the figure, this utility model embodiment also provides a data cable injection molding device, including: an injection molding assembly 6 and a rotating mechanism; The injection molding assembly 6 includes an injection molding machine 61, a moving mold 63, and a fixed mold 62; the injection molding machine 61 is mounted on the top of the mounting frame 5 and is used to inject molten material into the mold; the moving mold 63 is mounted on the bottom of the injection molding machine 61 and is driven by the driving device 64 to complete the mold opening and closing actions of the injection molding machine 61. The fixed mold 62 is fixedly mounted on the base 1 and located directly below the moving mold 63, fitting together with the moving mold 63 to form a complete injection molding cavity.

[0037] In this embodiment of the invention, the injection molding machine 61 is mounted on the base 1 via a mounting bracket 5, and is responsible for melting the molten material and injecting it under high pressure. The moving mold 63 is mounted below the injection unit of the injection molding machine 61 and is typically connected to the drive unit 64 of the injection molding machine 61. Driven by the drive unit 64 of the injection molding machine 61, it can perform vertical mold opening and closing actions. The fixed mold 62 is fixedly mounted on the base 1 of the rotating mechanism and is located directly below the moving mold 63. Its position corresponds to the stop position of a certain carrier 4 station on the rotating mechanism. When the moving mold 63 descends and presses against the fixed mold 62, the two together close to form an injection cavity that matches the shape of the data cable connector.

[0038] In one embodiment of this invention, at a non-injection molding station of the rotating mechanism, the metal end of the data cable is inserted into the interface of the positioning component 42 of the carrier 4, and the cable is placed into the V-shaped slot of the fixing frame 431. The carrier 4, containing the data cable, is delivered to the injection molding station by rotating the rotary table 2 at a set cycle. When the carrier 4 reaches the injection molding station, the rotary table 2 stops. The drive device 64 of the injection molding machine 61 presses down on the ejection mechanism 41 of the carrier 4, causing the carrier 4 to descend as a whole, and the metal end of the data cable is precisely inserted into the predetermined position in the cavity of the fixed mold 62. Simultaneously, the moving mold 63 descends rapidly with the drive device 64 of the injection molding machine 61, tightly closing with the fixed mold 62. Subsequently, the injection molding machine 61 injects molten material into the closed cavity, encasing the metal end of the data cable. After cooling, the drive device 64 of the injection molding machine 61 drives the upper mold and injection unit to rise rapidly. When the external downward pressure is removed, the ejection mechanism 41 under the carrier 4 quickly resets under the action of the spring, lifting the carrier 4 and the already injection-molded data cable away from the fixed mold 62. Then the rotary table 2 rotates again, sending the molded part to the next station, while the new part to be processed is sent into the injection molding station.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
