Bushing for cross fan of air conditioner and molding method of cross fan

摘要

The present invention relates to a cross fan bushing and a method of forming a cross fan of an air conditioner to reduce production costs and improve molding workability.;In the present invention, in forming a cross fan 100 for an air conditioner in which a plurality of radially formed blades 142 orthogonally concentrically on one side edge of a disc-shaped frame 140 having a circular hole in the center thereof, a circular shape The bushing 120, which is vertically positioned at the center of the hole and is formed on the shaft of the motor, is injection molded with a hard resin, and the plate 200 which is integrally coupled to the center of the bushing 120 is formed concentrically. The injection molding is made of soft resin, and the circumferential surface of the plate 200 is integrally formed while simultaneously sandwiching the upper and lower surfaces of the inner circumferential surface of the circular hole of the frame 140. The bushing 120 and the bushing 120 The plate 200 which is coupled to the lower circumferential surface of the plate 200 is molded into a hard and soft resin, respectively, and is integrally coupled to each other, and the plate 200 is inserted into the frame 140 by insert injection or ultrasonic wave. Mounting the can improve the workability of the molding as well as to be effective to reduce the production cost.
