Equal-wall-thickness centrifugal casting device for improving smoothness of inner wall of marine pipe fitting

The equal-wall-thickness centrifugal casting device for improving the smoothness of the inner wall of the marine pipe fitting comprises a supporting plate, a rotationally-connected mold is arranged at the top of the supporting plate, a liquid injection hopper is arranged at the position, on one side of the mold, of the top of the supporting plate, and a quantifying assembly is arranged at the position, on one side of the liquid injection hopper, of the top of the supporting plate. The top of the supporting plate is symmetrically provided with rotationally-connected first rotating shafts on the two sides of the mold, the outer walls of the first rotating shafts are provided with a plurality of driving rollers, and the top of the supporting plate is provided with a vibration assembly above the mold. According to the device, metal liquid for casting pipe fittings each time can be accurately controlled, so that the wall thickness of the pipe fittings cast through the device is uniform, resource waste is reduced,
