Synthetic fiber shaping device

The utility model belongs to the technical field of synthetic fiber production, particularly relates to a synthetic fiber shaping device, and aims to solve the problems that a mold is difficult to take and the working efficiency is greatly reduced due to the fact that the mold is positioned in a device body after the synthetic fiber is shaped in the prior art, the following scheme is provided: the synthetic fiber shaping device comprises a main body, a motor is fixedly connected to the inner wall of the bottom of the main body, a first gear is fixedly connected to one end of an output shaft of the motor, a hollow plate is fixedly connected to the position, located on the left side of the motor, of the inner wall of the bottom of the main body, and a threaded pipe is rotationally connected into the hollow plate. The shaping mold can be automatically fixed by starting the motor, synthetic fibers can be conveniently shaped, meanwhile, when an output shaft of the motor rotates reversely, the supporting plate can
