This utility model relates to a PVC board bending mold device, including an inner rolling mold component and an outer rolling mold component. Its advantages are that, through the coordinated operation of the inner and outer rolling mold components, bending of high-temperature PVC boards can be achieved. Using this mold device reduces manual labor time in the processing of high-temperature PVC boards, as the PVC board is pressed directly by the weight of the mold itself, eliminating the need for manual shaping and resulting in a more aesthetically pleasing shape. Furthermore, since the PVC board reaches a high temperature after heating, directly pressing it with the mold reduces the risk of burns to operators, improving the safety of the processing operation.

The application provides an outer rotor motor, which comprises a rotor assembly, a rotor shell, a stator assembly and a bearing. The end of the rotor assembly is connected with the axial end of the rotor shell, so that the rotor assembly can rotate integrally with the rotor shell. The bearing is located at the inner periphery of the axial end of the rotor shell to support the rotor shell. The axial other end of the rotor shell extends to the radial outer periphery of at least part of the structure of the stator assembly. The rotor shell can be driven to rotate by the stator assembly, so as to drive the rotor assembly to rotate integrally. According to the application, the arrangement of one bearing can be effectively reduced. Compared with the conventional outer rotor motor structure which needs to be provided with two bearings, or the scheme of one long bearing, the cost of one small but high-priced bearing is effectively saved, so that the cost of the outer rotor motor is reduced, and the noise and vibration are also reduced.
