Description

Technical Field

[0001] This utility model relates to the field of injection molding cooling technology, and in particular to a cooling mechanism for injection molding parts of wire harness connectors. Background Technology

[0002] With the rapid development of the electronics and automotive industries, the demand for wire harness connectors is increasing, and higher requirements are being placed on their quality and production efficiency. In the production process of injection-molded wire harness connectors, the cooling process is a key factor determining product quality and production cycle.

[0003] However, in the existing technology, for injection molded wire harness connectors with complex shapes, the air cooling method often cannot guarantee uniform cooling of various parts due to its limited heat dissipation capacity, resulting in problems such as insufficient or uneven cooling in certain areas. This uneven cooling process can easily cause quality defects such as uneven internal stress, warping deformation, and decreased dimensional accuracy of the parts, thereby affecting the assembly accuracy and service life of the product. Utility Model Content

[0004] The purpose of this invention is to solve the problem that uneven cooling processes in the prior art can easily lead to quality defects such as uneven internal stress, warping deformation, and decreased dimensional accuracy in the parts. Therefore, a cooling mechanism for injection molded wire harness connectors is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cooling mechanism for injection-molded wire harness connectors, comprising a base plate, a groove formed on the top of the base plate, a movable frame slidably connected to the surface of the groove, and a flipping mechanism installed on the top of the movable frame;

[0006] The flipping mechanism includes a fixed frame, a rotating rod rotatably connected to the center of the fixed frame, a rotating frame fixedly connected to the top of the rotating rod, multiple movable rods rotatably connected to the outer surface of the rotating frame, a flipping plate fixedly connected to one end of each movable rod, limit grooves opened on both sides of the rotating frame, a limit frame provided below the limit grooves, the top of the limit frame fixedly connected to the top of the inner cavity of the rotating frame, and a movable frame fixedly connected to one end of each movable rod.

[0007] Preferably, two limiting blocks are symmetrically fixedly connected to the inner side of the movable frame.

[0008] Preferably, a support rod is fixedly connected to the center of the bottom of the fixed frame, and the bottom end of the rotating rod passes through the support rod.

[0009] Preferably, the top and bottom of the flip plate are both engaged with limiting plates, and a screw is threadedly connected to one side of the top of the limiting plate, with the bottom end of the screw threadedly connected to the flip plate.

[0010] Preferably, the limiting block is slidably connected to the limiting groove.

[0011] Preferably, a drive motor is installed at the center of the top of the mobile frame, and the output end of the drive motor is fixedly connected to the rotating rod.

[0012] Preferably, a mounting bracket is fixedly connected to the top of the base plate, and a fan is mounted on the surface of the mounting bracket.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the precise control of the flipping mechanism ensures that the surface of the injection molded part is uniformly subjected to the cooling airflow, effectively avoiding uneven cooling and thus improving the cooling effect and production efficiency. The flipping plate is cooled by the airflow of the fan, and combined with the synchronous flipping of the rotating frame, it ensures that the cooling time of each surface of the injection molded part is consistent, reducing quality problems caused by local overheating or insufficient cooling. At the same time, the design of the movable frame and the limiting block effectively controls the stability of the flipping process and avoids shaking or jamming caused by uneven force during the flipping process.

[0015] 2. In this utility model, the sliding mechanism within the groove allows the flipping mechanism to move flexibly from under the mounting frame, simplifying the placement and removal process of the injection molded parts and improving production efficiency. The limiting plate plays a role in precise positioning and fixing during the placement of the injection molded parts, ensuring that the injection molded parts will not shift or tilt during cooling. The through-hole design of the limiting plate promotes uniform cooling of the injection molded parts, preventing deformation caused by heat accumulation. The small area of ​​edge shielding effectively reduces the impact on the cooling effect, while the design of surface heat dissipation holes further optimizes the cooling efficiency, ensuring rapid heat conduction and avoiding excessively high temperatures that could affect subsequent process operations, thus improving the stability and efficiency of the entire cooling process.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-4 As shown, this utility model provides a cooling mechanism for injection molded wire harness connectors, including a base plate 1, a groove 11 is opened on the top of the base plate 1, a movable frame 4 is slidably connected to the surface of the groove 11, and a flipping mechanism 5 is installed on the top of the movable frame 4.

[0024] The flipping mechanism 5 includes a fixed frame 53, a rotating rod 52 rotatably connected to the center of the fixed frame 53, a rotating frame 51 fixedly connected to the top of the rotating rod 52, a plurality of movable rods 56 rotatably connected to the outer surface of the rotating frame 51, a flipping plate 54 fixedly connected to one end of the movable rod 56, a limit groove 511 is opened on both sides of the rotating frame 51, a limit frame 58 is provided below the limit groove 511, the top of the limit frame 58 is fixedly connected to the top of the inner cavity of the rotating frame 51, and a movable frame 55 is fixedly connected to one end of the movable rod 56.

[0025] The specific setup and function of this embodiment will be described in detail below. During the cooling process, the injection molded part to be cooled is first placed inside the flip plate 54 to ensure the stability and efficiency of the cooling process. At this time, multiple fans 3 start working to provide uniform airflow cooling to the surface of the injection molded part, thereby accelerating the heat dissipation process and improving production efficiency. During this process, the output of the drive motor 41 drives the rotating rod 52 to rotate through the transmission mechanism, thereby driving the rotating frame 51 connected to it to rotate synchronously.

[0026] When the rotating frame 51 rotates, the multiple flipping plates 54 on it move accordingly, realizing the overall flipping operation. At the same time, a movable rod 56 is connected to one side of the flipping plate 54, which further drives the movable frame 55 to move during the flipping process. When the movable frame 55 enters the limiting groove 511 along the set motion trajectory, the limiting block 551 on the inner side of the movable frame 55 is subject to the dual constraint of the limiting groove 511 and the limiting frame 58, thereby limiting the limiting block 551 at a specific position and causing it to flip. This flipping action is further transmitted to the movable frame 55, and finally drives the flipping plate 54 to flip as a whole, causing the injection molded part placed on it to flip.

[0027] This flipping process ensures that all surfaces of the injection molded part are exposed to the cooling airflow, effectively preventing uneven cooling and improving the cooling effect. Furthermore, the flipping mechanism 5, through its reasonable limit design, ensures the smoothness and stability of the flipping process, avoiding shaking or jamming caused by uneven force during flipping, thus improving the reliability and service life of the equipment.

[0028] Example 2: Figure 2 and Figure 3 As shown, two limiting blocks 551 are symmetrically fixedly connected to the inner side of the movable frame 55. A support rod 57 is fixedly connected to the bottom center of the fixed frame 53, and the bottom end of the rotating rod 52 passes through the support rod 57. The top and bottom of the flip plate 54 are both snapped with limiting plates 541, and a screw 542 is threadedly connected to one side of the top of the limiting plate 541. The bottom end of the screw 542 is threadedly connected to the flip plate 54. The limiting blocks 551 are slidably connected to the limiting grooves 511. A drive motor 41 is installed at the top center of the movable frame 4, and the output end of the drive motor 41 is fixedly connected to the rotating rod 52. A mounting frame 2 is fixedly connected to the top of the base plate 1, and a fan 3 is installed on the surface of the mounting frame 2.

[0029] The overall effect of this embodiment is that the sliding function of the movable frame 4 plays a crucial role in the handling and placement of injection molded parts. By sliding inside the slide groove 11, the movable frame 4 can quickly and flexibly move the flipping mechanism 5 out from under the mounting frame 2, making the placement of injection molded parts to be cooled and the removal of injection molded parts that have been cooled more efficient and convenient.

[0030] When placing the injection molded part, the two limiting plates 541 play a crucial positioning role. The limiting plates 541 precisely hold the injection molded part in place and are fixed by adjusting the screws 542, ensuring the injection molded part remains stable during cooling and does not move or tilt. The limiting plates 541 have a unique structural design; the through-hole in the center not only aids in the cooling of the injection molded part but also prevents deformation caused by heat buildup.

[0031] Furthermore, the edge design of the limiting plate 541 takes into account the obstruction issue of the injection molded part, employing a smaller obstruction area to minimize the impact of the limiting plate 541 on the cooling effect of the injection molded part. To further optimize the cooling effect, multiple heat dissipation holes can be formed on the surface of the limiting plate 541. These holes not only enhance the heat dissipation capacity of the limiting plate 541 but also ensure that heat can be quickly conducted to the surface of the injection molded part, accelerating its cooling process and preventing subsequent process operations from being affected by excessive temperature.

[0032] The device is used as follows: The injection molded part to be cooled is placed inside the flipping plate 54. During the cooling process, multiple fans 3 are used to cool the injection molded part. During this process, the output of the drive motor 41 drives the rotating rod 52 to rotate, which in turn drives the rotating frame 51 to rotate, causing the rotating frame 51 to move along with multiple flipping plates 54. During this movement, the movable rod 56 on one side of the flipping plate 54 drives the movable frame 55 to move together. When the movable frame 55 passes through the limiting groove 511, the inner limiting block 551 is affected by the combined action of the limiting groove 511 and the limiting frame 58, causing the limiting block 551 to push the movable frame 55 to flip, thereby causing the flipping plate 54 to flip as well. This allows the injection molded part to be cooled to flip, thus improving the cooling effect and uniformity.

[0033] When picking up and placing injection molded parts, the movable frame 4 slides within the slide groove 11, facilitating the removal of the flipping mechanism 5 from under the mounting frame 2. This completes the placement of the injection molded parts to be cooled and the removal of the cooled parts. During placement, the injection molded parts are fixed in place by two limiting plates 541, which are then secured by screws 542. The through-hole in the middle of the limiting plate 541 allows for convenient cooling of the injection molded parts. Furthermore, the edges of the two limiting plates 541 minimize obstruction of the injection molded parts, and multiple heat dissipation holes can be provided on the surface of the limiting plates 541 to prevent them from affecting the cooling effect of the injection molded parts.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
