A mold exchanger of a pipe manufacturing line is provided to assemble the next molder while the exchanged molder molds a pipe and to rapidly and accurately exchange the molder for another one. A mold exchanger of a pipe manufacturing line comprises an operating rail(131), a fixed rail(132), a vehicle rail(133), an replacing vehicle(135) and an incoming and outgoing rail(136). The operating rail is installed in the lower part of a molding frame so that a molder(100) goes in and comes out of a molding spot. The fixed rail is installed in front of the operating rail. The vehicle rail is installed in front of the fixed rail. The replacing vehicle supplies or draws the molder. The incoming and outgoing rail is installed to coincide with the fixed rail. The operating unit is equipped with a lifting member to be lifted when a pipe is exchanged and a controller for preventing the molder from being moved.
