Description

Technical Field

[0001] This utility model relates to the field of license plate processing technology, and in particular to a multi-mold selection mechanism for hydraulic forming of license plates. Background Technology

[0002] Through customized letter molds, mold frames, and hydraulic systems, metal sheets can be precisely pressed into license plate shapes that conform to national standards or industry specifications, ensuring uniformity in license plate size and appearance across the country or region. The characters and anti-counterfeiting marks required for the license plate are pre-engraved on the mold, the mold frame is used to fix the placement of the letter mold, and the hydraulic pressure can create a uniform depth and neat edge texture on the surface of the metal sheet.

[0003] Currently, each type of license plate requires a corresponding mold frame of specific specifications. If a company needs to produce multiple types of license plates in a short period of time, it will need to frequently change mold frames and adjust material positions. Moreover, this operation still uses a relatively traditional manual method, requiring operators to manually measure and place the plates. This is not only time-consuming and labor-intensive, but also prone to positioning errors due to human factors, making it difficult to meet the needs of large-scale, high-precision production.

[0004] In response to the technical problem of frequently changing mold frames and adjusting material positions when producing multiple types of license plates in a short period of time, this application proposes a multi-mold frame selection mechanism for license plate hydraulic forming. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem of frequent mold frame changes and material position adjustments during the production of multiple types of license plates in a short period of time. It proposes a multi-mold frame selection mechanism for license plate hydraulic forming. A controller operates a motor, which rotates a threaded rod and moves the mounting frame on the outer wall, moving different mold frame bodies at the top to the underside of the stamping plate. This ensures that different mold frames are accurately placed in their designated positions on the hydraulic forming equipment, avoiding redundant operations caused by frequent mold frame changes and significantly improving production efficiency. Simultaneously, by controlling a bidirectional motor and an electric push rod, the positions of the sliding plates and movable plates on both sides are adjusted to accommodate materials of different sizes. This prevents problems such as size discrepancies and character offsets after license plate forming due to material position deviations, ensuring the quality of license plate production.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A multi-mold selection mechanism for license plate hydraulic forming includes a processing table. A motor is fixedly connected to the right end of the processing table. A threaded rod is fixedly connected to the drive end of the motor. A mounting frame is threadedly connected to the outer wall of the threaded rod. A mold frame body is connected to the inner wall of the mounting frame via a snap-fit ​​assembly for disassembling and assembling the mold frame body. Sliding frames are slidably connected to both sides of the inner wall of the processing table. A bidirectional motor is fixedly connected to the inner wall of each sliding frame. Movable components are provided on both drive ends of the bidirectional motors to adjust the position of materials of different sizes. A hydraulic rod is fixedly connected to the top of the processing table. A stamping plate is fixedly connected to the bottom end of the hydraulic rod. The outer wall of the mounting frame is slidably connected to the inner wall of the processing table.

[0008] Furthermore, the buckle assembly includes a connecting frame fixedly connected to the bottom end of the mold frame body, and the inner wall of the connecting frame is provided with a slot.

[0009] Furthermore, each of the card slots has a card block on its inner wall, the shape of which matches the card slot. A pull rod is slidably connected to the inner wall of the mounting frame, and the outer wall of the pull rod is fixedly connected to the inner wall of the card block.

[0010] Furthermore, the outer wall of the pull rod is provided with a threaded rod three, the inner wall of the mounting frame is provided with a threaded groove, and the outer wall of the threaded rod three is set on the inner wall of the threaded groove.

[0011] Furthermore, the active component includes gears fixedly connected to one drive end of the bidirectional motor, and the outer walls of the gears are meshed with toothed plates, the outer walls of the toothed plates being fixedly connected to the inner wall of the processing table.

[0012] Furthermore, each of the two-way motors has a threaded rod fixedly connected to its other drive end. The outer wall of the threaded rod is threaded with a sliding plate, and the outer wall of the sliding plate is slidably connected to the inner wall of the sliding frame.

[0013] Furthermore, electric push rods are fixedly connected to both ends of the sliding frame, and movable plates are fixedly connected to the inward ends of the electric push rods. The outer walls of the movable plates are slidably connected to the inner walls of the sliding frame.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the motor is controlled by the controller to rotate the threaded rod and move the mounting frame on the outer wall, moving the different mold frame bodies at the top to the lower side of the stamping plate. This ensures that different mold frames are accurately placed in the designated position of the hydraulic forming equipment, avoiding redundant operations caused by frequent mold frame changes and significantly improving production efficiency.

[0016] 2. In this utility model, by controlling the bidirectional motor and the electric push rod, the positions of the sliding plates and the movable plates on both sides are adjusted respectively, and the positions of materials of different sizes are adjusted to prevent problems such as inconsistent size and character offset after the license plate is formed due to material position deviation, thus ensuring the production quality of the license plate.

[0017] 3. In this utility model, the mold frame can be removed by rotating the threaded rod and pulling the pull rod to the right, and the mold frame in the installation frame can be replaced. The replacement of the mold frame can reduce equipment downtime, improve overall production efficiency, and meet the market demand for rapid delivery of diverse license plates.

A mounting frame 14 is threadedly connected to the outer wall of the threaded rod 13. Multiple mold frame bodies 20 are arranged on the inner wall of the mounting frame 14. A hydraulic rod 2 is fixedly connected to the top of the processing table 1. A stamping plate 3 is fixedly connected to the bottom end of the hydraulic rod 2. The outer wall of the mounting frame 14 is slidably connected to the processing table 1. The bottom of the mold frame body 20 is fixedly connected to a connecting frame 18. The inner wall of the connecting frame 18 is provided with a slot 19. The inner wall of the slot 19 is provided with a block 17. The shape of the block 17 fits the slot 19.

The outer wall of the threaded rod 16 is located on the inner wall of the threaded groove for disassembling and assembling the mold frame body 20.

[0029] Specifically, during installation, first insert the connecting frame 18 at the bottom of the mold frame body 20 into the mounting frame 14. After installation, push the pull rod 15 to the left to engage the locking blocks 17 into the locking slots 19. Then, rotate the threaded rod 16 in the opposite direction to rotate it into the threaded groove. This completes the installation. By rotating the threaded rod 16 and pulling the pull rod 15 to the right, the mold frame can be removed and replaced in the mounting frame.

[0030] Reference Figures 3-5 As shown, sliding frames 4 are slidably connected to both sides of the inner wall of the processing table 1. Bidirectional motors 5 are fixedly connected to the inner wall of the sliding frames 4. Gears 6 are fixedly connected to one drive end of the bidirectional motors 5. Gear plates 7 are meshed with the outer wall of the gears 6. The outer wall of the gear plates 7 is fixedly connected to the inner wall of the processing table 1. Threaded rods 8 are fixedly connected to the other drive end of the bidirectional motors 5. Sliding plates 9 are threadedly connected to the outer wall of the threaded rods 8.

[0031] For details, please refer to Figure 1 A controller is installed at the front end of the processing table 1. The controller is electrically connected to the hydraulic rod 2, bidirectional motor 5, electric push rod 10, and electric motor 12. The PLC or embedded controller automatically selects the target mold frame body 20 according to preset parameters, realizing the function of automatically selecting and switching the mold frame body 20. This ensures that the selected mold frame body 20 automatically enters the working area of ​​the press, ensuring that different mold frames are accurately placed in the designated position of the hydraulic forming equipment. This avoids redundant operations caused by frequent mold frame changes and significantly improves production efficiency. When one side of the bidirectional motor 5 is rotating, the other side will not rotate. The other side can only be started after one side has finished rotating. By controlling the bidirectional motor 5 and the electric push rod 10, the positions of the sliding plates 9 and the movable plates 11 on both sides are adjusted respectively to adjust the position of materials of different sizes. This prevents problems such as inconsistent size and character offset after the license plate is formed due to material position deviation, thus ensuring the quality of license plate production.

[0032] Working principle: First, the controller controls the motor 12 to rotate, driving the threaded rod 13 to rotate and moving the mounting frame 14 on the outer wall, moving the top die frame body 20 to the underside of the stamping plate 3, and placing the material on the die frame body 20; Second, the controller controls the outer drive end of the bidirectional motor 5 to drive the gear 6 to rotate, causing the gear 6 to rotate on the outer wall of the toothed plate 7, and driving the sliding frames 4 on both sides to move to both sides of the material, and activating the inner drive end of the bidirectional motor 5 and the electric push rod 10, the bidirectional motor 5 drives the threaded rod 8 to rotate, moving the sliding plates 9 on both sides inward to press the material. Adjust both sides; then, the electric push rod 10 drives the movable plates 11 on both sides to move inward to adjust the position of the material on both sides. After the adjustment is completed, the movable plates 11 and the sliding plates 9 are moved outward respectively, and the hydraulic rod 2 is extended to drive the stamping plate 3 to move downward to stamp the material; finally, when it is necessary to replace the mold frame body 20, first rotate the threaded rod 16 to remove the threaded rod 16 from the threaded groove, and pull the pull rod 15 to the right. The pull rod 15 drives the locking block 17 on the outer wall to move, and remove the locking block 17 from the locking groove 19. Then the mold frame body 20 can be taken out upward to complete the disassembly.
