Description

Technical Field

[0001] This utility model relates to the field of automotive mold technology, specifically a combined automotive mold. Background Technology

[0002] In the automotive manufacturing industry, car bodies and numerous components are typically formed from sheet metal through stamping. The core of the stamping process lies in using dies to impart specific shapes and structures to the sheet metal. Currently, mainstream automotive stamping dies generally employ a basic structure where an upper die and a lower die work together. During processing, the sheet metal is placed on top of the lower die. Driven by a press, the upper die moves downward and closes with the lower die. Strong pressure forces the sheet metal to undergo plastic deformation or separation, thereby precisely obtaining the desired contour of the automotive parts. This upper and lower die combination structure is the foundation for achieving efficient, mass-production stamping.

[0003] However, existing integrated automotive stamping dies have significant limitations. When producing automotive parts of different shapes or sizes, the entire upper and lower die set must be frequently changed because each part typically requires a dedicated die. Automotive dies are generally large, complex in structure, and incredibly heavy. The changeover process is not only time-consuming and labor-intensive, requiring specialized lifting equipment and skilled workers, but also leads to frequent production line downtime, severely restricting production efficiency. Especially when producing small batches of customized or prototype parts, the cost of manufacturing a large, dedicated die for each part is extremely high, and the storage, management, and maintenance of the dies also impose additional burdens. This "one die per part" model results in huge capital investment and resource waste, making it difficult to adapt to the flexible production demands of modern automotive manufacturing for multiple varieties, small batches, and rapid response.

[0004] Based on this, a modular automobile mold is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0026] In one embodiment, such as Figures 1-8 As shown, a combined automotive mold includes an upper mold base 11 and a lower mold base 17. The upper mold base 11 is positioned above the lower mold base 17. The upper mold base 11 is fixedly connected to the output ends of several electric cylinders 14. The electric cylinders 14 are installed in mounting holes at the upper end of a top plate 15. The top plate 15 is fixedly mounted on the upper end of an operating table 16. Several mounting seats 12 are evenly spaced at the bottom end of the upper mold base 11. Upper mold blocks 13 are mounted inside the mounting seats 12. The lower mold base 17 is fixedly mounted on the upper end of the operating table 16. The lower mold base 17 has several lower mold blocks 18 evenly spaced inside. Each lower mold block 18 has a support base 19 fixedly mounted at its bottom. The lower mold base 17 has a fixing mechanism on one side corresponding to the position of the lower mold block 18 for fixing the support base 19. The lower mold base 17 has a clamping mechanism on top for positioning and clamping the workpiece. The fixing mechanism facilitates quick installation, fixing and disassembly of the lower mold blocks 18. The clamping mechanism facilitates positioning the workpiece before the upper mold block 13 processes it.

[0027] The fixing mechanism includes limiting posts 20. Positioning plates are fixedly provided on the inner side of the lower mold base 17 at positions corresponding to both sides of the support base 19. A first sliding hole is provided on one side of the lower mold base 17 at a position corresponding to the two positioning plates. A second sliding hole is provided on one side of the support base 19 at a position corresponding to the first sliding hole. Limiting posts 20 are slidably installed within the first sliding holes. A guide block 21 is fixedly provided at one end of each limiting post 20. The upper end of each guide block 21 is inclined. A first fixing plate is fixedly provided at the upper end of each guide block 21. A first guide slide rod is slidably installed in the middle of each first fixing plate. The first guide slide rods are all fixedly installed on the lower mold base 17. A first return spring 22 is provided between the first fixing plate and one end of each first guide slide rod. A lower pressing block 23 is slidably installed at the upper end of each guide block 21. The guide block 21 has a limiting groove on one side, and the lower pressing block 23 has a second guide slide rod slidably mounted on both ends. The second guide slide rod is fixed on the lower mold base 17. A second return spring 24 is provided between both ends of the lower pressing block 23 and one end of the second guide slide rod. In use, when it is necessary to replace part of the lower mold block 18, the user pushes the lower pressing block 23, and the lower pressing block 23 slides on the inclined surface at the upper end of the guide block 21. When the lower pressing block 23 moves, the guide block 21 drives the limiting post 20 to slide in the first sliding hole. When the lower pressing block 23 moves to the position of the limiting groove, under the action of the first return spring 22, the lower pressing block 23 moves into the limiting groove and is fixed. At this time, one end of the limiting post 20 is disengaged from the second sliding hole, so that the lower mold block 18 can be removed for replacement.

[0028] The lower mold block 18 has grooves on both sides, which facilitates the placement and removal of the lower mold block 18 during use.

[0029] The clamping mechanism includes a fixed limiting frame 25 and a sliding limiting frame 27. The lower mold base 17 is symmetrically equipped with the fixed limiting frame 25 and the sliding limiting frame 27 along its length and width directions, respectively. Fixed tubes 32 are slidably mounted on both ends of the fixed limiting frame 25 and the sliding limiting frame 27. Stop plates 33 are slidably mounted inside each fixed tube 32. An anti-slip layer is provided on one side of each stop plate 33. The stop plate 33 is rotatably mounted on one end of a screw. A threaded hole is provided on one side of each fixed tube 32 corresponding to the screw position. The fixed limiting frame 25 has two fixed tubes 37. Both of the components are fixedly mounted on the upper end of the fixed base 26, which is fixedly mounted on the upper end of the operating table 16. The two fixed tubes 32 on the sliding limit frame 27 are both fixedly mounted on the upper end of the sliding frame 29. The sliding frame 29 has a third guide slide rod slidably mounted at both ends. The third guide slide rod is fixedly mounted on one side of the fixed plate. The fixed plate is fixedly mounted on the upper end of the operating table 16. Several third return springs 28 are provided between one side of the sliding frame 29 and one side of the fixed plate. The upper mold block 13 has drive components at both ends for driving the sliding limit frame 27 to move and position.

[0030] The driving assembly includes a guide plate 30. The upper end of the sliding frame 29 is fixedly provided with a guide plate 30. One end of the guide plate 30 is inclined. The upper mold block 13 is fixedly provided with a top frame 31 at both ends. One end of the top frame 31 is aligned with the inclined end of the guide plate 30. One end of the top frame 31 is fixedly provided with a rotating frame. The inner side of the rotating frame is provided with a rotating roller. In use, when it is necessary to process the workpiece, the workpiece is placed on the upper end of the lower mold block 18. Then, the electric cylinder 14 is started to drive the upper mold seat 11 to move. The upper mold seat 11 drives the upper mold block 13 and the top frame 31 to move. When the rotating roller is in close contact with the inclined end of the guide plate 30, the guide plate 30 drives the sliding frame 29 to move. The sliding frame 29 drives the sliding limit frame 27 to slide, so that the sliding limit frame 27 positions and clamps the workpiece. When the rotating roller is in close contact with the flat part of the guide plate 30, the sliding limit frame 27 no longer moves.

[0031] The bottom of the operating table 16 is provided with a fixed frame, and a collection box 34 is slidably installed inside the fixed frame, which facilitates the collection of waste generated during processing.

[0032] The above embodiment discloses a combined automotive mold. When it is necessary to replace part of the lower mold block 18, the user pushes the lower pressing block 23. The lower pressing block 23 slides on the inclined surface of the upper end of the guide block 21. When the lower pressing block 23 moves, the guide block 21 drives the limiting post 20 to slide in the first sliding hole. When the lower pressing block 23 moves to the position of the limiting groove, under the action of the first return spring 22, the lower pressing block 23 moves into the limiting groove, thereby fixing the lower pressing block 23. At this time, one end of the limiting post 20 disengages from the second sliding hole, thereby allowing the lower mold block 18 to be replaced. When the workpiece needs to be processed, it is placed on the upper part of the lower mold block 18. Then, the electric cylinder 14 is started to drive the upper mold seat 11 to move. The upper mold seat 11 drives the upper mold block 13 and the top frame 31 to move. When the rotating roller is in close contact with the inclined end of the guide plate 30, the guide plate 30 drives the sliding frame 29 to move. The sliding frame 29 drives the sliding limit frame 27 to slide, so that the sliding limit frame 27 positions and clamps the workpiece. When the rotating roller is in close contact with the flat part of the guide plate 30, the sliding limit frame 27 stops moving, thus completing the positioning and clamping of the workpiece.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
