The lower mold-closing assembly 7 is mounted on the intermediate support 12 and located below the casting station 10. The first guide assembly 3 is mounted on the upper support 11 and distributed in the transverse direction. The movable seat 4 is mounted on the first guide assembly 3. The first linear drive assembly 2 is connected to the movable seat 4 and is used to drive the movable seat 4 to move along the guide direction of the first guide assembly 3. The upper mold-closing assembly 6 is mounted on the movable seat 4 and passes through the side... The mold closing assembly 5, the upper mold closing assembly 6, and the lower mold closing assembly 7 drive the mold closing and opening of the casting mold. The material receiving assembly 9 is located on the intermediate support 12 and is located on the periphery of the casting station 10. In this embodiment, the structure of the casting mold consists of an upper mold, a lower mold, a side mold assembly, and a standard mold frame. The side mold assembly is a 4-open side mold assembly, that is, it is composed of 4 side molds combined into a whole side mold assembly. Each side mold is an integral structure and is installed on the side mold closing assembly. The upper mold and the lower mold are installed on the upper mold closing assembly and the lower mold closing assembly, respectively.

[0018] This wheel hub machine uses a mold opening and closing device. During use, the side mold closing assembly 5, upper mold closing assembly 6, and lower mold closing assembly 7 drive the various parts of the casting mold to close, and pour liquid alloy into the casting mold. After cooling and solidification, the mold is opened. The first linear drive assembly 2 drives the upper mold closing assembly 6 to move along the guide direction of the first guide assembly 3, and the second linear drive assembly 16 drives the upper mold closing assembly 6 to move in the vertical direction. This causes the cast wheel hub to move in the horizontal and vertical directions and transfer to the receiving assembly 9, and then the receiving assembly 9 transfers it out.

The third linear drive assembly 92 is connected to the receiving tray 94 and is used to drive the receiving tray 94 to move along the guide direction of the second guide assembly 93, so that the receiving tray 94 can move in the vertical direction. In cooperation with the upper mold assembly 6, it can move accurately and smoothly to the appropriate position, which is convenient for receiving the cast wheel hub and avoids damage to the wheel hub due to collisions during the receiving process, thereby further improving the quality and efficiency of wheel hub production.

[0020] Meanwhile, the side-clamping mold assembly 5 includes a first mounting base 51, a front connecting base 52, a rear connecting base 53, a fourth linear drive assembly 54, multiple second guide rods 55, and multiple second guide sleeves 56. The first mounting base 51 is disposed on the intermediate support 12, each of the second guide sleeves 56 is circumferentially disposed on the first mounting base 51, and each of the first guide rods 55 passes through each of the second guide sleeves 56. The rear connecting base 53 is disposed on one end of each of the second guide rods 55 away from the casting station 10. The two ends of the fourth linear drive assembly 54 are connected to the first mounting base 51 and the rear connecting base 53. The front connecting seat 52 is located on one end of each second guide rod 55 near the casting station 10. The first mounting seat 51 is fixed on the intermediate support 12 to provide support for the whole. The second guide sleeve 56 and the second guide rod 55 cooperate to guide the movement of the front connecting seat 52 and the rear connecting seat 53. The fourth linear drive assembly 54 provides power to drive the rear connecting seat 53 to move, thereby driving the front connecting seat 52 to achieve the mold closing action. This structure makes the movement of the side mold closing assembly 5 more precise and stable, which is conducive to improving the mold closing quality and reducing wheel hub casting defects caused by inaccurate mold closing.

[0021] Furthermore, the upper mold-closing assembly 6 includes a second mounting base 61, an upper connecting base 62, a lower connecting base, a fifth linear drive assembly 64, multiple third guide rods 65, and multiple third guide sleeves 66. The second mounting base 61 is disposed on the upper support 11, each of the third guide sleeves 66 is disposed on the second mounting base 61, and each of the third guide rods 65 passes through each of the third guide sleeves 66. The upper connecting base 62 is disposed at the upper end of each of the third guide rods 65. The two ends of the fifth linear drive assembly 64 are connected to the second mounting base 61 and the upper connecting base 62, and the lower connecting base is disposed at the lower end of each of the third guide rods 65. The fifth linear drive assembly 64 provides power to drive the upper connecting base 62 to move, thereby driving the lower connecting base to realize the mold-closing action. This structure makes the movement of the upper mold-closing assembly 6 more precise and stable, which is conducive to improving the mold-closing quality and reducing wheel hub casting defects caused by inaccurate mold-closing.

[0022] In this embodiment, the lower mold assembly 7 and the upper mold assembly 6 are axially symmetrically distributed.
