Description

Technical Field

[0001] This utility model relates to the field of wire harness coating technology, and in particular to a tooling for a module for coating automotive wire harnesses to prevent mixing of materials and misaligned parts. Background Technology

[0002] Wire harness coating is a common manufacturing process in modern electronic products. It effectively protects the wire harness from problems such as wear, friction, and electromagnetic interference. Therefore, mastering wire harness coating techniques is an essential skill in the electronic product manufacturing process.

[0003] When encapsulating automotive wiring harnesses, traditional methods can only produce sleeves of the same color at a time. If different colors of sleeves are to be produced, the materials need to be re-mixed and injection molded. This requires emptying the original material from the injection molding machine cavity, which delays the encapsulation process. At the same time, during encapsulation, operators are prone to encapsulating wire harnesses of different specifications and thicknesses incorrectly, resulting in incorrect encapsulation. To avoid the above problems, a modular tooling for preventing mixed materials and incorrect encapsulation of automotive wiring harnesses is needed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a module tooling for preventing mismatched parts in automotive wiring harnesses.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A tooling for an automotive wiring harness anti-mixing and misalignment part coating module includes a lower mold, an upper mold mounted above the lower mold, a wiring harness body placed between the lower mold and the upper mold, and a coating plastic being injection molded onto the surface of the wiring harness body. A fixing plate and a flow channel plate are fixedly connected to the inner wall of the upper mold. A molding groove is provided on the opposite surfaces of the lower mold and the upper mold. An injection hole is provided on the upper surface of the upper mold. A flow diversion and anti-misalignment part coating mechanism is provided on the surface of the lower mold.

[0006] Preferably, the flow diversion and anti-misalignment component coating mechanism includes a flow diversion groove formed on the surface of the lower mold, a flow channel formed on the surface of the flow channel plate, a first partition plate fixedly connected to the inner wall of the flow channel, and the flow channel and the flow diversion groove are positioned corresponding to each other.

[0007] Furthermore, the lower mold and the upper mold have multiple glue inlet channels on their opposite surfaces, and the inner wall of the flow channel plate has a separation groove connected to the glue inlet channels. The inner wall of the glue inlet channels is connected to the inner wall of the molding groove.

[0008] Preferably, a second partition plate is fixedly connected to the inner wall of the injection hole, and the lower surface of the second partition plate is in contact with the upper surface of the upper mold.

[0009] Furthermore, a movable ring is slidably connected to the inner wall of the fixed plate, and an arc-shaped plate is fixedly connected to one end of the movable ring. The main body of the wire harness is installed inside the arc-shaped plate.

[0010] Preferably, a first spring and a second spring are fixedly connected to the inner wall of the fixed plate, and the ends of the first spring and the second spring that are close to each other are fixedly connected to the surface of the movable ring. A first pressure sensor alarm and a second pressure sensor alarm are fixedly connected to the inner wall of the fixed plate, and the movable ring is installed between the first pressure sensor alarm and the second pressure sensor alarm.

[0011] The beneficial effects of this utility model are as follows: 1. High-temperature molten plastic of different colors is injected through both sides of the second partition plate and guided by the diversion channel into the diversion channel. Under the conveying of the separation channel, it enters the glue inlet channel and injects glue into the inner cavity of the molding tank to form plastic coatings of different colors on the left and right sides.

[0012] 2. When the main body of the wire harness is placed inside the arc-shaped plate, if the diameter of the main body of the wire harness is large, it will drive the arc-shaped plate to push the movable ring to contact the surface of the first pressure sensor alarm and sound an alarm. If the diameter of the main body of the wire harness is small, the movable ring will press the surface of the second pressure sensor alarm under the action of the second spring and sound an alarm. If the wire harness does not sound an alarm when it is placed, its diameter is qualified. The advantage of doing this is to prevent the operator from mistakenly wrapping wire harnesses of different thicknesses. Attached Figure Description

A molding groove 20 is provided on the opposite surfaces of the lower mold 1 and the upper mold 2. An injection hole 19 is provided on the upper surface of the upper mold 2. A flow diversion and anti-misalignment part coating mechanism is provided on the surface of the lower mold 1.

[0017] By setting the molding groove 20, the plastic 4 is injection molded and coated. By setting the injection hole 19, the injection operation is carried out. By setting the diversion and error prevention coating mechanism, the coating operations of different colors can be carried out at the same time, and the error of coating is effectively avoided.

[0018] In this utility model, reference is made to Figure 2 and Figure 4 The flow diversion and anti-misalignment coating mechanism includes a flow diversion groove 9 opened on the surface of the lower mold 1, a flow channel 8 opened on the surface of the flow channel plate 7, and a first partition plate 17 fixedly connected to the inner wall of the flow channel 8. The flow channel 8 and the flow diversion groove 9 are positioned corresponding to each other.

[0019] By setting up the diversion channel 9, plastics of different colors on both sides of the diversion channel 9 flow into the corresponding diversion channel 8, and the first partition plate 17 is used to block and isolate them.

[0020] In this utility model, reference is made to Figure 2 Multiple injection channels 5 are provided on the opposite surfaces of the lower mold 1 and the upper mold 2. A separation groove 16 is provided on the inner wall of the channel plate 7. The separation groove 16 is connected to the injection channels 5. The inner wall of the injection channels 5 is connected to the inner wall of the molding groove 20.

[0021] By setting up the glue inlet channel 5, the plastic is injected into the molding tank 20 for molding, and by setting up the separation tank 16, the high-temperature melted plastic is guided and conveyed.

[0022] In this utility model, reference is made to Figure 5 The inner wall of the injection hole 19 is fixedly connected to a second partition plate 18, and the lower surface of the second partition plate 18 is in contact with the upper surface of the upper mold 2.

[0023] By setting a second partition plate 18, isolated conveying is achieved during glue injection.

[0024] In this utility model, reference is made to Figure 3 The inner wall of the fixed plate 6 is slidably connected to a movable ring 15, and one end of the movable ring 15 is fixedly connected to an arc-shaped plate 10. The main body of the wire harness 3 is installed inside the arc-shaped plate 10.

[0025] By setting the arc plate 10, the main body of the wire harness 3 is placed smoothly, and the movable ring 15 is moved.

[0026] In this utility model, reference is made to Figure 3 The inner wall of the fixed plate 6 is fixedly connected to a first spring 14 and a second spring 13. The ends of the first spring 14 and the second spring 13 that are close to each other are fixedly connected to the surface of the movable ring 15. The inner wall of the fixed plate 6 is fixedly connected to a first pressure sensor alarm 12 and a second pressure sensor alarm 11. The movable ring 15 is installed between the first pressure sensor alarm 12 and the second pressure sensor alarm 11.

[0027] By setting the first spring 14 and the second spring 13, the positioning of the movable ring 15 is kept stable. By setting the first pressure sensor alarm 12 and the second pressure sensor alarm 11, when the surface of the movable ring 15 comes into contact with the surface of the first pressure sensor alarm 12 or the second pressure sensor alarm 11, an alarm is issued to inform the operator that the thickness of the wire harness body 3 placed in the arc plate 10 does not meet the production requirements.

[0028] Working principle: When injecting glue into the injection hole 19, high-temperature molten plastic of different colors is injected through both sides of the second partition plate 18 and guided by the diversion groove 9 into the diversion channel 8. The first partition plate 17 separates and blocks the different colored glue materials. Under the conveying of the separation groove 16, it enters the glue inlet channel 5 and injects glue into the inner cavity of the molding groove 20 to form a plastic coating 4. When the wire harness body 3 is placed into the arc plate 10, when the diameter of the wire harness body 3 is large, it drives the arc plate 10. The plate 10 pushes the movable ring 15 into contact with the surface of the first pressure sensor alarm 12, triggering an alarm. When the diameter of the wire harness body 3 is small, the movable ring 15, under the action of the second spring 13, presses the surface of the second pressure sensor alarm 11, triggering an alarm. When the wire harness body 3 is placed in the appropriate size within a pair of arc-shaped plates 10, the movable ring 15 is located between the first pressure sensor alarm 12 and the second pressure sensor alarm 11, preventing the operator from mistakenly wrapping wire harness bodies 3 of different thicknesses.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
