The invention discloses a centrifugal casting mold with an inner convex casting and capable of realizing bidirectional movement. The centrifugal casting mold comprises a bottom plate, a mold body anda transmission mechanism installed below the mold body, wherein a driving device is fixedly installed on the upper surface of the bottom plate, a spraying device is installed on the side, away from the driving device, of the upper surface of the bottom plate, sliding rails are symmetrically and fixedly connected to the upper surface of the bottom plate, sliding seats are slidably connected to thetops of the sliding rails, a supporting plate is fixedly connected to the tops of the two sliding seats, the transmission mechanism is fixedly connected to the top of the supporting plate, the mold body is mounted at the movable end of the transmission mechanism in a matched mode, a first through hole is formed in one side of the mold body, a second through hole is formed in the end, away from thefirst through hole, of the mold body, an annular groove is formed in the middle of the inner wall of the mold body. By operating the driving device, bidirectional movement of the casting mold can beachieved, automatic spraying of the casting mold can be achieved, and the centrifugal casting mold is higher in efficiency and safer.
