Structure improvement used for input shaft assembly injection molding machine

A structure improvement used for input shaft assembly injection molding machine, which comprises an injection molding machine, wherein a workpiece feeding port is arranged on the side wall of the injection molding machine; in the injection molding machine, a slide heating slideway is fixed between the workpiece feeding port and a workpiece taking port in the front of the injection molding machine; the heating slideway is internally provided with an electric heating rod and a temperature sensor that are electrically connected with an electric control device on the injection molding machine; and a constant temperature heating start switch is arranged on the electric control device. As the heating slideway where an input shaft can slide and be placed is fixed on the injection molding machine, when the heating slideway is preheated, the structure improvement solves the problem that water and rust preventing oil are remained on the input shaft after the input shaft is cleaned, avoids the problem that the remaining
