Die for manufacturing hollow fender post through centrifugal method

The utility model relates to a die for manufacturing a hollow fender post by a centrifugal method. The die comprises an upper half steel die, a lower half steel die, a concave movable die strip and a convex movable die strip, the upper half steel die and the lower half steel die are connected together to form a hollow die body inner cavity; rectangular long grooves for placing the concave movable die strip and the convex movable die strip respectively are reserved in the left side and the right side of an inner cavity of the hollow die body, and the concave movable die strip and the convex movable die strip are detachably and replaceably mounted in the rectangular long grooves in the left side and the right side. The concave movable die strip and the convex movable die strip are detachably and replaceably installed, if two fender posts with oval cross sections are different in concave-convex structures, only two sets of different concave movable die strip and convex movable die strip need to be designed, and
