[0002] A wheel hub, also known as a rim, is a cylindrical component on an axle that supports the tire. Common small car wheel hubs are usually made of aluminum alloy. Currently, aluminum alloy wheel hub manufacturing in my country is still mainly based on low-pressure casting using wheel hub molds.

[0003] Currently, in existing technologies, aluminum alloy wheel hub molds are usually fixed to the mold base of the casting device using multiple bolts. However, the multi-bolt installation method makes the replacement and maintenance of aluminum alloy wheel hub molds inconvenient. Therefore, it is necessary to propose a replacement component for aluminum alloy wheel hub processing molds. Summary of the Invention

[0004] To address the shortcomings of existing technologies, particularly the inconvenience of replacing existing aluminum alloy wheel hub molds, this invention proposes a replacement assembly for aluminum alloy wheel hub processing molds. Furthermore, this invention also provides a method for using the aforementioned replacement assembly for aluminum alloy wheel hub processing molds.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a replacement component for aluminum alloy wheel hub processing mold, including a base, a mold base fixedly connected to the top of the base, a locking mechanism provided in the inner cavity of the mold base, and a wheel hub mold provided on the top of the mold base; The locking mechanism includes an adjusting rod rotatably connected to the side wall of the mold base cavity. A gear is fixedly connected to the middle of the outer wall of the adjusting rod, and threaded sleeves are fixedly connected to both ends of the outer wall of the adjusting rod. A first locking rod is provided on the outer wall of the threaded sleeve, which engages with the wheel hub mold. A positioning sleeve is fixedly connected to the top of the mold base cavity, and the gear is rotatably connected to the inner cavity of the positioning sleeve. Racks mesh on both sides of the gear, and one end of the rack extends out of one side of the positioning sleeve and is fixedly connected to a second locking rod, which engages with the wheel hub mold.

[0006] Preferably, the outer wall of the threaded sleeve is threadedly connected to a connecting plate, and one end of the first clamp is fixedly connected to the top of the connecting plate.

[0007] Preferably, a positioning rod is fixedly connected to one side of the inner wall of the mold base, and one end of the positioning rod passes through both sides of the connecting plate and is slidably connected to the connecting plate.

[0008] Preferably, the end of the first locking rod extends out of the top of the mold base and is slidably connected to the mold base. A first locking groove is provided on one side of the wheel hub mold, and the first locking rod is engaged with the first locking groove.

[0009] Preferably, the inner cavity of the positioning sleeve has a rotating groove, the gear is rotatably connected inside the rotating groove, and the adjusting rod passes through both sides of the positioning sleeve and is rotatably connected to the positioning sleeve.

[0010] Preferably, the inner cavity of the positioning sleeve is provided with guide grooves on both sides near the rotating groove, and the rack is slidably connected inside the guide grooves.

[0011] Preferably, the end of the second locking rod extends out of the top of the mold base and is slidably connected to the mold base. A second locking groove is provided on one side of the wheel hub mold, and the second locking rod is engaged with the second locking groove.

[0012] The method for using the replacement components for aluminum alloy wheel hub machining molds includes the following steps: First, install the wheel hub mold on the mold base at the top of the base. Use the locking mechanism to lock the wheel hub mold in the horizontal and vertical directions. Rotate the adjusting rod, which drives the threaded sleeve and gear to rotate synchronously. The threaded sleeve rotates and drives the connecting plate to move. The connecting plate moves stably with the positioning rod and drives the first locking rod to move. The first locking rod moves and locks in the first slot of the wheel hub mold. The adjusting rod drives the gear to rotate in the rotating groove of the positioning sleeve. The gear rotates and drives the rack to move in the guide groove. The rack moves and drives the second locking rod to move. The end of the second locking rod is locked in the second slot, thus making the first locking rod and the second locking rod stably lock the wheel hub mold. When replacing, rotate the adjusting rod in the opposite direction to move the end of the first locking rod out of the first slot and the end of the second locking rod out of the second slot.

[0013] The advantages of this invention are: This invention mounts the wheel hub mold on the top of the mold base on the base. A first and second locking rod are used to lock the wheel hub mold horizontally and vertically, respectively, thus securing the mold firmly to the top of the mold base. During replacement, rotating the adjusting rod causes it to rotate, simultaneously driving the threaded sleeve and gear to rotate. The rotation of the threaded sleeve drives the first locking rod to move and release the locking of the wheel hub mold. The gear rotates and, in conjunction with the rack, drives the second locking rod to move and release the locking of the wheel hub mold, allowing for easy disassembly of the wheel hub mold. This significantly improves the convenience of wheel hub mold replacement and solves the problem of insufficient convenience in replacing existing aluminum alloy wheel hub molds.
