The invention provides a molding machine of an impeller with a handle, and belongs to the technical field of impeller manufacturing. The molding machine comprises a working tabletop, a feeding mechanism, a cutting mechanism, a station rotating disc and a shaping mechanism, wherein the feeding mechanism is arranged at one end of the working tabletop; the feeding mechanism is provided with a circular groove for containing an abrasive belt roll, a feeding wheel for driving an abrasive belt to move and a compressing wheel for compressing and positioning the abrasive belt; the cutting mechanism is used for shearing the abrasive belt and arranged on one side of the feeding mechanism in the conveying direction of the abrasive belt roll; the station rotating disc is used for containing a base body and arranged inside a discharging area of the cutting mechanism; the shaping mechanism comprises a shaping strip; the shaping strip is connected with a shaping driving device for driving the shaping strip to stretch out and retract; and the shaping strip points to the station rotating disc, and an included angle formed between the shaping strip and the conveying direction of the abrasion belt is an acute angle. The molding machine of the impeller with the handle completes multiple procedures such as abrasive belt slicing, arranging and shaping, the automatic degree is high, no artificial participation is needed any more, the technology repeatability is good, and the production efficiency is high.
