The outer shaping mold 3 is arranged on the periphery of several inner mold bodies 23. The outer shaping mold 3 includes a third driving component 31 and an outer mold body 32. The third driving component 31 is connected to the frame 1, and the outer mold body 32 is rotatably connected to the output end of the third driving component 31.

The second driving assembly 24 drives each inner mold body 23 to move toward the outside of the circle formed by the plurality of inner mold bodies 23, so that the outer edge contour formed by the plurality of inner mold bodies 23 matches the inner diameter of the wheel rim 100. The third driving assembly 31 drives the outer mold body 32 to press against the outer wall of the wheel rim 100. The first driving assembly 21 drives the plurality of inner mold bodies 23 and the wheel rim 100 on the plurality of inner mold bodies 23 to rotate relative to the outer mold body 32 through the connecting piece 22, and the roundness of the wheel rim 100 is shaped by rolling the wheel rim 100 by the outer mold body 32, thereby realizing automatic shaping of the wheel rim 100 and improving the shaping efficiency of the wheel rim 100.

[0051] Optionally, in order to simplify the structure of the second driving assembly 24, the inner mold body 23 in this embodiment includes a connecting block 231 and a mold body 232, a slide groove is provided on the connecting member 22, part of the connecting block 231 is located in the slide groove, an elastic member is provided in the slide groove, one end of the elastic member is connected to the inner wall of the slide groove, and the other end of the elastic member is connected to one end of the connecting block 231 away from the central axis of the plurality of inner mold bodies 23. The mold body 232 is connected to the connecting block 231. Through the cooperation of the slide groove, the elastic member and the inner mold body 23, the plurality of inner mold bodies 23 are in a condensed state in a natural state, that is, the diameter of the outer edge contour formed by the plurality of inner mold bodies 23 is in a minimum state, which can facilitate the rim 100 to be sleeved on the plurality of inner mold bodies 23. When the wheel rim 100 needs to be shaped, the second driving assembly 24 only needs to drive the plurality of inner mold bodies 23 to move radially outward of the circumference formed by the plurality of inner mold bodies 23 to open the wheel rim 100, that is, the diameter of the outer circular contour formed by the plurality of inner mold bodies 23 matches the inner diameter of the wheel rim 100.
