[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figure 1-4As shown, an interchangeable forging die for automotive wheel flange inserts includes a lower forging die 1 and an upper forging die 2 for wheel flanges. The lower forging die 1 has a lower wheel flange forming part 3, and the upper forging die 2 has an upper wheel flange forming part 4. The lower wheel flange forming part 3 and the upper wheel flange forming part 4 are positioned and matched in shape. The lower forging die 1 has a central groove forming structure 5 that passes through the lower forging die 1 and corresponds to the position of the lower wheel flange forming part 3. The upper forging die 2 has a sliding sealing forming part 6, and the length of the central groove forming structure 5 is greater than the length of the sliding sealing forming part 6.

[0026] In this embodiment, during the forging process, the central groove forming structure 5 can simultaneously form the central groove structure of the automotive wheel hub flange with the cooperation of the lower forming part 3 of the wheel hub flange; the sliding sealing forming part 6 is tightly fitted in the corresponding position to play a sealing role, preventing the leakage of molten metal during the forging process, improving the forming quality of the product. After production is completed, the mold is opened, and the central groove forming structure 5 and the sliding sealing forming part 6 are extracted and interchanged. The formed product is ejected and demolded through the central groove forming structure 5. Compared with traditional molds, there is no need for an additional complex ejection mechanism, which simplifies the ejection structure, makes the internal layout of the mold simpler and more reasonable, and reduces the manufacturing and maintenance costs of the mold.

[0027] Combination Figure 3 , Figure 4 As shown, the central groove forming structure 5 includes a lower die center slide rod 7 disposed in the lower die 1 for forging the wheel hub flange. The top of the lower die center slide rod 7 is provided with a central groove forming shaft 8. The lower die center slide rod 7 is in sliding fit with the lower die 1 for forging the wheel hub flange.

[0028] Specifically, during the forging process, the lower die center slide bar 7 can slide up and down in the wheel hub flange forging lower die 1 through an external drive device, thereby driving the top center groove forming shaft 8 to move, realizing the precise forming of the center groove structure of the automobile wheel hub flange. This sliding fit design makes the movement of the center groove forming structure 5 more stable and flexible, greatly improving the forming accuracy and stability, and reducing forming defects caused by structural jamming.

[0029] Combination Figure 4 As shown, the diameter of the central groove forming shaft 8 gradually decreases from the end closest to the center slide bar 7 of the lower mold to the end furthest away.

[0030] In this embodiment, the design gives the central groove structure of the molded automotive wheel hub flange a specific taper, making it easier for the product to separate from the mold during demolding, reducing demolding resistance, preventing damage to the product during demolding, and at the same time, the central groove structure with a specific taper also enhances the structural strength of the product and improves product quality.

[0031] The bottom of the lower die center slide rod 7 is provided with a first interchangeable mold fitting 9. The first interchangeable mold fitting 9 is slidably engaged with the lower die 1 for forging the wheel hub flange. The first interchangeable mold fitting 9 includes a first mold fitting block 10 disposed at the bottom of the lower die center slide rod 7. The diameter of the first mold fitting block 10 is larger than the diameter of the lower die center slide rod 7.

[0032] In this embodiment, the first interchangeable mold closing component 9 includes a first mold closing insert 10 disposed at the bottom of the lower mold center slide rod 7. The diameter of the first mold closing insert 10 is larger than the diameter of the lower mold center slide rod 7. During the mold opening and closing process, the first mold closing insert 10 slides in the lower mold 1 for forging the wheel hub flange and cooperates with the second mold closing insert 13 on the top of the sliding sealing molding component 6 to achieve precise mold closing and opening operations. Moreover, this design facilitates the interchangeability of the central groove forming structure 5 and the sliding sealing molding component 6 during mold maintenance or parts replacement, thereby improving the maintainability of the mold.

[0033] The sliding sealing molding component 6 includes a sealing cylinder 11 disposed in the upper mold 2 for forging the hub flange, and the bottom of the sealing cylinder 11 is provided with a groove forming protrusion 12.

[0034] In this embodiment, during forging, the sealing cylinder 11 and the groove forming protrusion 12 fit together tightly to form a sealed environment inside the mold, effectively preventing molten metal leakage. At the same time, the groove forming protrusion 12 fits precisely with the central groove forming shaft 8 to further form the central groove structure of the automobile wheel hub flange, ensuring the accuracy and integrity of product forming and improving the product forming quality.

[0035] The diameter of the groove-shaped protrusion 12 is smaller than the diameter of the sealing cylinder 11.

[0036] In this embodiment, this design creates a stepped structure between the sealing cylinder 11 and the groove-forming protrusion 12, increasing the sealing path and greatly enhancing the sealing effect, preventing molten metal from leaking from the connection between the two. In addition, it facilitates the precise matching between the groove-forming protrusion 12 and the central groove-forming shaft 8, improving the forming accuracy of the central groove structure.

[0037] Combination Figure 3-4 As shown, the top of the sealing cylinder 11 is provided with a second mold fitting block 13. The diameter of the second mold fitting block 13 is larger than the diameter of the sealing cylinder 11, and the diameter of the second mold fitting block 13 is the same as the diameter of the first mold fitting block 10.

[0038] In this embodiment, during the mold closing process, the first mold closing insert 10 and the second mold closing insert 13 cooperate with each other and fit tightly to ensure the sealing and stability of the mold, prevent misalignment or leakage during the mold closing process, and at the same time, the design of the same diameter facilitates the disassembly and maintenance of the mold and reduces the maintenance difficulty.

[0039] Combination Figure 1-4 As shown, the lower part 3 of the wheel flange forming includes a lower wheel flange forming cavity 14 disposed in the lower die 1 of the wheel flange forging, and the upper part 4 of the wheel flange forming includes an upper wheel flange forming cavity 15 disposed in the upper die 2 of the wheel flange forging, with the lower wheel flange forming cavity 14 and the upper wheel flange forming cavity 15 facing each other.

[0040] In this embodiment, during forging, the heated metal billet is placed in the lower cavity 14 of the wheel hub flange forming. As the upper die 2 of the wheel hub flange forging moves downward, the upper cavity 15 of the wheel hub flange forming and the lower cavity 14 of the wheel hub flange forming are closed. Under the combined action of the two, the outer shape structure of the automobile wheel hub flange is precisely formed.

[0041] The working principle of this utility model is as follows:

[0042] The lower cavity 14 for forming the wheel hub flange is installed inside the lower die 1 for forging the wheel hub flange. The central sliding rod 7 of the lower die passes through the lower cavity 14, and the first mold clamping block 10 is installed at its bottom, so that the central sliding rod 7 and the first mold clamping block 10 slide in cooperation with the lower die 1 for forging the wheel hub flange. The upper cavity 15 for forming the wheel hub flange is installed inside the upper die 2 for forging the wheel hub flange, and the sealing cylinder 11 is installed above the upper cavity 15. The groove forming protrusion 12 is installed at the bottom of the sealing cylinder 11, and the second mold clamping block 13 is installed at the top, ensuring that the sealing cylinder 11 and the groove forming protrusion 12 cooperate with the upper die 2 for forging the wheel hub flange. The heated metal billet is placed in the lower cavity 14 for forming the wheel hub flange, and then the upper die 2 for forging the wheel hub flange is driven. The downward movement causes the upper cavity 15 of the wheel hub flange forming mold to close with the lower cavity 14 of the wheel hub flange forming mold. During the mold closing process, the first mold closing insert 10 and the second mold closing insert 13 cooperate with each other to ensure the sealing and stability of the mold. At the same time, the sealing cylinder 11 and the groove forming protrusion 12 seal the inside of the mold to prevent molten metal leakage. The lower mold center slide rod 7 drives the middle groove forming shaft 8 to move upward, cooperating with the groove forming protrusion 12 to simultaneously form the middle groove structure of the automotive wheel hub flange. After forging, the upper mold 2 of the wheel hub flange forging is driven to move upward to open the mold, and the middle groove forming structure 5 and the sliding sealing forming part 6 are extracted and interchanged. Then, by driving the lower mold center slide rod 7 to move upward, the middle groove forming shaft 8 is used to eject the formed automotive wheel hub flange product from the mold and demold it.
