the wire rotating motor is suitable for driving the wire rotating gear to rotate so as to drive the wire pressing gear to synchronously rotate through the wire rotating gear.

10. A method of operating a molding machine, comprising:

straightening the wire rod by a rotary straightening mechanism;

sending the straightened continuous wire rod into a first forming mechanism through a wire feeding mechanism;

bending and cutting off the wire rod for the first time through an upper end forming mechanism;

rotating the primarily bent wire rod by a rotating and clamping mechanism;

bending and molding the wire rod after the rotation angle again through a second molding mechanism; and

and the wire rod which is bent and formed again is discharged to the storage rack through the pressing wire rotating mechanism.
