The utility model relates to an injection molding machine extrusion port leakage-proof structure which comprises a fixed seat, a hydraulic rod fixedly connected to the top of the fixed seat, a mounting rack fixedly connected to the hydraulic rod through a screw, a heating ring welded to one end of the mounting rack, a fixed tank penetrating through the middle of the heating ring, and a connecting pipe fixedly connected to one end of the bottom of the fixed tank. The liquid storage device has the advantages that liquid is prevented from flowing back through the check valve, and redundant liquid can be pumped and collected into the storage box through the pump body at one end of the bottom of the fixed tank to be stored; redundant liquid can be stored through the storage box, meanwhile, the situation that the liquid drips to affect the quality of the model is prevented, the motor is used for driving the rotating shaft to rotate, plastic in the storage box is conveniently stirred, and heating is more uniform; th
