Abstract

A bending mold device for bidirectional pipe bending includes a mounting base which is horizontally arranged on a rack in a sliding manner. The mounting base includes a translation lead screw driving the mounting base to slide. The rack includes a lead screw nut. A pipe bending spindle is rotatably disposed on the mounting base and a power mechanism is disposed on the mounting base. The upper end of the pipe bending spindle is movably connected to a lower rotating base. The lower rotating base includes a first pipe bending shaft and a second pipe bending shaft, which respectively include a first bending mold lower mold and a second bending mold lower mold. The rack includes a cylinder above the lower rotating base. The end part of a piston rod of the cylinder fixedly includes an upper limiting plate and a lower limiting plate in a sleeving manner.
