Description

Technical Field

[0001] This utility model relates to the field of sealing strip corner mold technology, and in particular to a quick corner mold for automotive door frame sealing strips. Background Technology

[0002] In automobile manufacturing, door frame sealing strips are crucial components for ensuring the airtightness of car doors and windows, and their corner treatment technology is vital for the connection effect of the sealing strips. Typically, the corners of the sealing strips require a heat-fusion process to fuse the two ends together at the contact point. However, because car door frames vary in shape, traditional molds can usually only accommodate a specific door frame shape. Therefore, during the corner-joining process, the sealing strip needs to be bent to fit the shape of the car door frame.

[0003] For example, Chinese utility model patent application number 202420644177.4 discloses a quick-connect corner mold for automotive door frame sealing strips, which includes: a base, two first sealing blocks and a second sealing block on the upper end of the base, a first slot and a second slot on the upper end of the base, vertical rods on both sides of the first slot and the second slot, a movable plate slidably connected between two connected vertical rods, and a first block and a second block respectively on the lower surface of the two movable plates. Through this structure, the first slot engages with the first block, and the second slot engages with the second block, thereby positioning the sealing strip, keeping it stable, and preventing displacement.

[0004] Traditional sealing strip corner fitting molds typically use fixed-shape molds. During production, these molds need to be custom-made according to the shape of different car door frames, which not only increases production costs but also affects production efficiency. Furthermore, during the bending and corner fitting of the sealing strip, the fixed shape of the mold prevents flexible adjustment, resulting in poor fixing and clamping of the sealing strip and some stability issues. This is especially true when clamping sealing strips of different widths, frequently requiring mold replacements. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a quick corner fitting mold for automotive door frame sealing strips.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a quick corner fitting mold for automotive door frame sealing strips, comprising a mold base, two rotating rods rotatably connected to the inner bottom surface of the mold base, the top ends of the two rotating rods rotatably extending to the outside of the mold base and fixedly connected to a support block, an adjustment component provided on the inner bottom surface of the mold base, an adjustment plate fixedly installed on the top of the support block, a groove provided on the top of the adjustment plate, two moving blocks slidably connected to the inner wall of the groove, a driving component for driving the two moving blocks to move relative to or away from each other provided on one side of the adjustment plate, a contact component provided on the top of the moving blocks, a moving frame fixedly installed on the top of the mold base, detachable components provided on both sides of the moving frame, a slide rail fixedly connected between the two sides of the inner wall of the moving frame, and a connecting component provided on the outer wall of the slide rail.

[0007] The mold base is the basic support structure of the entire device, providing the position for fixing and supporting other components, ensuring the stable operation of the entire mold system. The rotating rod is used to connect the mold base with the external support block.

[0009] The adjustment assembly includes a servo motor installed on the inner bottom surface of the mold base. The output end of the servo motor is fixedly connected to a drive gear, and the outer wall of the drive gear is meshed with an auxiliary gear.

[0010] The auxiliary gear is rotatably connected to the inner top surface of the mold base via a rotating shaft. The servo motor drives the gear, causing the rotating rod to rotate relative to it, thereby adjusting the bending angle of the sealing strip.

[0011] As a further description of the above technical solution:

[0012] The outer wall of the driving gear, on the side furthest from the auxiliary gear, and the outer wall of the auxiliary gear are both meshed with connecting gears.

[0017] As a further description of the above technical solution:

[0018] The contact assembly includes a clamping plate fixedly mounted on the top of the movable block, and rubber pads are fixedly connected to opposite sides of the two clamping plates.

[0019] The rubber pad features a diamond-patterned surface design, which prevents slipping and avoids damaging the sealing strip surface.

[0020] As a further description of the above technical solution:

[0021] The detachable component includes a pyramidal block 1 fixedly installed on both sides of the movable frame, a triangular block slidably connected to the outer wall of the pyramidal block 1, and a pyramidal block 2 fixedly connected to one side of the triangular block.

[0022] The triangular block is slidably connected to and adapted to the pyramidal block 2 on another triangular block, and there are at least four triangular blocks and pyramidal blocks 2.

[0023] As a further description of the above technical solution:

[0024] The top of the triangular block is slidably connected to a locking pin, one end of which slides through both pyramid block one and pyramid block two.

[0025] The locking pin is slidably connected to the top of the triangular block, ensuring that the pyramid block and the triangular block will not loosen or fall off due to vibration during adjustment, thus guaranteeing the stability and safety of the device.

[0026] As a further description of the above technical solution:

[0027] The connecting assembly includes a connecting seat that is slidably connected to the outer wall of the slide rail. A hand-tightening screw is threaded through one side of the connecting seat, and a push block is rotatably connected to one end of the hand-tightening screw.

[0028] The hand-tightening screw drives the push block to move, ensuring a firm joint. At the same time, the connecting seat can be manually adjusted to move on the slide rail and adjust the degree of bending.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figure 1-5 This utility model provides a quick corner fitting mold for automotive door frame sealing strips: It includes a mold base 1, with two rotating rods rotatably connected to the inner bottom surface of the mold base 1.

An adjustment component is provided on the inner bottom surface of the mold base 1. An adjustment plate 4 is fixedly installed on the top of the support block 3. A groove 5 is opened on the top of the adjustment plate 4, and two moving blocks 6 are slidably connected to the inner wall of the groove 5. A driving component is provided on one side of the adjustment plate 4 to drive the two moving blocks 6 to move relative to or away from each other. A contact component is provided on the top of the moving blocks 6. A moving frame 7 is fixedly installed on the top of the mold base 1. Detachable components are provided on both sides of the moving frame 7. A slide rail 8 is fixedly connected between the two sides of the inner wall of the moving frame 7. A connecting component is provided on the outer wall of the slide rail 8. The mold base 1 is the basic support structure of the entire device, providing positions for fixing and supporting other components, ensuring the overall stability of the device. The mold system operates stably. The rotating rod 2 connects the mold base 1 to the external support block 3. By rotating, the support block 3 and the entire upper structure can rotate or move to a certain extent, ensuring that the device can complete the required angle adjustment. The slide 5, as the motion track on the adjustment plate 4, provides a guiding function, allowing the moving block 6 to slide smoothly in it to complete the task of fixing the sealing strip. Through the coordinated use of the adjustment component, drive component, contact component, and adjustment plate 4, the rotation of the active gear 10 and auxiliary gear 11 can be driven by the servo motor 9, which can accurately adjust the angle and shape of the sealing strip, so that it can automatically adapt to different shapes and sizes of car door frames, reducing the trouble of traditional molds needing to be customized separately. Furthermore, through the cooperation of the drive rod 13 and the bidirectional lead screw 14, the sealing strip can be stably clamped, avoiding the sealing strip from sliding or deviating in position during placement, and improving the stability and accuracy of the joint.

[0041] The adjustment assembly includes a servo motor 9 installed on the inner bottom surface of the mold base 1. The output end of the servo motor 9 is fixedly connected to a drive gear 10. An auxiliary gear 11 is meshed with the outer wall of the drive gear 10. The interior of the auxiliary gear 11 is rotatably connected to the inner top surface of the mold base 1 via a rotating shaft. The servo motor 9 drives the gear, causing the rotating rod 2 to rotate relative to each other, thus adjusting the bending angle of the sealing strip. A connecting gear 12 is meshed with both the outer wall of the drive gear 10 and the outer wall of the auxiliary gear 11. The inner wall of the connecting gear 12 is fixedly connected to the rotating rod 2.

[0042] The drive assembly includes a drive rod 13 rotatably connected to one side of the adjustment plate 4. One end of the drive rod 13 rotatably passes through the interior of the slide groove 5 and is fixedly connected to a bidirectional lead screw 14. The outer wall of the bidirectional lead screw 14 is threadedly connected to two moving blocks 6, and one end of the bidirectional lead screw 14 is rotatably connected to the inner wall of the slide groove 5.

[0043] The contact assembly includes a clamping plate 15 fixedly mounted on the top of the movable block 6. A rubber pad 16 is fixedly connected to one side of each clamping plate 15. The surface of the rubber pad 16 has a diamond-pattern design, which is anti-slip and avoids damaging the surface of the sealing strip.

[0044] The detachable components include a pyramid block 17 fixedly installed on both sides of the movable frame 7. A triangular block 18 is slidably connected to the outer wall of the pyramid block 17. A pyramid block 29 is fixedly connected to one side of the triangular block 18. The triangular block 18 is slidably connected to and adapted to the pyramid block 29 on the other triangular block 18. There are at least four triangular blocks 18 and pyramid blocks 29. A locking pin 20 is slidably connected to the top of the triangular block 18. One end of the locking pin 20 slides through the pyramid block 17 and the pyramid block 29 respectively. The locking pin 20 is slidably connected to the top of the triangular block 18 to ensure that the pyramid block and the triangular block 18 will not loosen or fall off due to vibration during the adjustment process, thus ensuring the stability and safety of the device.

[0045] The connecting assembly includes a connecting seat 21 that is slidably connected to the outer wall of the slide rail 8. A hand-tightening screw 22 is threaded through one side of the connecting seat 21. A push block 23 is rotatably connected to one end of the hand-tightening screw 22. The hand-tightening screw 22 drives the push block 23 to move, ensuring the joint is firm. At the same time, the connecting seat 21 can be manually adjusted to move on the slide rail 8 to adjust the degree of bending.

[0046] Working principle: First, when using the product, the sealing strip that needs to be joined is bent to form an arc shape to fit the car door frame. At this time, the output of the servo motor 9 is started to drive the active gear 10 to rotate, which in turn drives the auxiliary gear 11 to rotate synchronously. At this time, through the same gear module, the active gear 10 rotates while driving the connecting gear 12 that meshes with it to rotate. Then, the auxiliary gear 11 rotates while driving another connecting gear 12 to rotate, so that the rotating rod 2 can rotate relative to each other, which in turn drives the adjusting plate 4 to rotate synchronously, so that the structure for placing the sealing strip rotates to fit the shape of the car door frame. Then it is placed into the two contact components. At this time, in order to ensure stability, the drive rod 13 can be turned to drive the bidirectional lead screw 14 to rotate, so that the two moving blocks 6 can move relative to each other or away from each other along the slide groove 5, which in turn drives the two clamping plates 15 to move, so that the two rubber pads 16 clamp the sealing strip to ensure the stability of the sealing strip when it is placed.

[0047] Then, to facilitate the heating and pressing of the sealing strip corner by the heating equipment, the sealing strip corner can be padded as needed to prevent the sealing strip corner from being suspended and bending. At this time, the triangular block 18 is inserted into the pyramid block 17, and then other triangular blocks 18 are inserted into the pyramid block 19 on another triangular block 18 as needed, so that the device can rotate to increase or decrease as needed. Then, the locking pin 20 is inserted into the triangular block 18 in sequence, so that it penetrates the pyramid block 17 and the pyramid block 19 respectively, ensuring that it will not fall off due to vibration. Before fixing, a suitable gap is left at the corner end. At this time, the two ends are placed on the connecting seat 21, and then the hand screw 22 is turned to move the pushing block 23, thereby pressing and fixing the two ends of the corner, which facilitates subsequent molding. At the same time, the connecting seat 21 can slide automatically so that the bending arc of the corner end matches the required door frame shape.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
