Example Embodiment
[0024] This embodiment is a horizontal and vertical combined split mold used in spinning forming of a large-scale complex curved bus bar thin-walled component with horizontal internal ribs. Including the mandrel head 1, the splint 2 and the mandrel tail 3, such as figure 1 As shown, the core mold head 1, the splint 2 and the core mold tail 3 are all rotating bodies. Among them, the splint 2 is located between the core mold head 1 and the core mold tail 3, and is sleeved on the positioning shaft of the core mold tail 3; the splint 2 and the core mold head 1 are hollow shells, and the splint 2 and the core The shape of the die head 1 is all curved bus-shaped. The inner hole of the core mold head 1 is a stepped hole; the diameter of the inner hole at one end of the core mold head 1 is the same as the outer diameter of the positioning shaft on the core mold tail 3, forming an assembly hole for the positioning shaft at the core mold tail; On the end face of part 1, the positioning ...
