According to the structure features of the plastic endless screw, the integral insert was applied to mold the spiral gear, and the screw insert was designed to eject to the molding parts. To realize the rotating ejection, the rotational transmitting device main part of the chain wheel was designed according to the features of the mold structure, and the rotational speed and teeth number of the chain wheel were analyzed and determined. The actual manufacturing shows the mold structure designed with the proposed method is simple but stationary, and the molding parts are more precise and smooth.
