The existing patent (Announcement No.: CN213732492U) discloses a centrifugal casting device for cement pipe pile production. The utility model sets a material loading and unloading motor, a threaded rod and a slider. By driving the threaded rod, the slider slides left and right, and then drives the hinged rod and the casting platform, so that the casting platform rotates around the rotating seat, and then switches the placement state of the casting platform, so as to facilitate the unloading operation of the hollow cement pipe pile between the inner mold rod and the outer mold barrel. However, in actual applications, since cement pipe piles have a variety of specifications, suitable specifications are selected according to different construction types. In the above utility model, it is not only difficult to disassemble the outer mold barrel, but also because a gear ring is installed on the outer mold barrel, it takes a lot of time to connect the gear ring and the gear plate after replacing the outer mold barrel, and the operation is cumbersome. To this end, we propose a centrifugal casting device for cement pipe pile production. Utility Model Content
