[0030] Among them Figure 1As shown, the traverse assembly includes a drive motor 4, a screw rod 3 and a connecting block 10. The drive motor 4 is installed on the side of the processing table 1. The screw rod 3 is arranged directly above the processing table 1 and fixed to the output end of the drive motor 4. The connecting block 10 is symmetrically arranged on the outside of the screw rod 3 and can move in the linear opposite direction of the screw rod 3. The connecting block 10 contacts the outer wall of the side mold 8. Specifically, the drive motor 4 can drive the screw rod 3 to rotate, and then the connecting block 10 can drive the side mold 8 to move in the linear direction of the screw rod 3, so that the side mold 8 can be quickly spliced ​​for subsequent filling of aluminum liquid. The upper end surface of the processing table 1 is symmetrically installed with slide rails 5. The two slide rails 5 are in parallel, and the upper end surface of the slide rail 5 is slidably connected with a slider 6. The upper end surface of the slider 6 is installed with a fixed plate 7, and the cross-section of the fixed plate 7 is an "L"-shaped structure. The fixed plate 7 contacts the outer wall of the side mold 8. Specifically, when the side molds 8 are close to each other, the fixed plate 7 connects the side mold 8 with the slider 6. The side mold 8 slides left and right along the linear direction of the slide rail 5 with the slider 6, so that when the side mold 8 is displaced, the structure is more stable. Engaging grooves 9 are provided on both sides of the side mold 8, and the left and right side molds 8 can be meshed and connected. Specifically, the engagement grooves 9 can ensure that the two side molds 8 are more tightly spliced ​​to prevent leakage.

Specifically, the upper mold 12 can be driven to move up and down along the linear direction of the slide bar 17 by the set hydraulic cylinder 16. The linear bearing 18 is used to limit the slide bar 17 for quick splicing, which is convenient for the subsequent quick removal of the molded wheel hub.

[0032] Among them Figure 3 As shown, an injection tube 14 is provided inside the lower mold 11, and an exhaust hole 13 is symmetrically opened on the upper end surface of the upper mold 12. Specifically, the molten metal is introduced into the mold cavity from the injection tube 14 from bottom to top through a low-pressure casting method, and the exhaust hole 13 can ensure that the air is discharged in time during pouring.

[0034] First, the processing table 1 is placed horizontally, and the supporting foot 2 is used to support the processing table 1. A lower mold 11 is arranged directly above the processing table 1. The drive motor 4 can drive the screw 3 to rotate, and then the connecting block 10 can drive the side mold 8 to move in the linear direction of the screw 3, so that the side mold 8 can be quickly spliced. Engaging grooves 9 are provided on both sides of the side mold 8. The engagement grooves 9 can ensure that the two side molds 8 are more tightly spliced ​​to prevent leakage. When the side molds 8 are close to each other, the fixed plate 7 connects the side mold 8 with the slider 6. The side mold 8 slides left and right along the linear direction of the slide rail 5 with the slider 6, so that when the side mold 8 is displaced, the structure is more stable. A gantry 15 is installed on the side of the processing table 1 for installing the lifting assembly.
