This utility model discloses a heating control device for a hot cutting knife of an extrusion blow molding machine, which includes an electric eye arranged on the inner side of the door frame of the injection molding machine cabinet for monitoring the outflow length of the plastic film. The electric eye is electrically connected to the heating control device for the hot cutting knife. The utility model monitors the plastic outflow length through the electric eye, and cuts off the power supply after the set temperature is reached when the plastic outflow length meets the preset value; in addition, the power supply is cut off and heating is stopped after the safety door is opened or the screw stops rotating, so as to eliminate potential harm and energy loss.
