s1, filling the interior of a blanking groove (9) with a material for injection molding, driving an extrusion molding screw rod (31) to rotate at a constant speed by a hydraulic motor (11), opening a flashboard at the bottom of the blanking groove (9), and enabling the injection molding material to enter the interior of a material receiving bin (19) from the bottom of the blanking groove (9);
s2, conveying the injection molding material to the inside of the extrusion molding pipe (7) by the extrusion molding screw (31), heating a temperature control ring (8) on the outer wall of the extrusion molding pipe (7), melting the injection molding material in the extrusion molding pipe (7), and pushing the melted injection molding material to an injection molding nozzle (6) under the extrusion of the extrusion molding screw (31);
s3, further heating the injection molding material through a high-temperature ring (24) at the end opening of the injection molding nozzle to ensure that the injection molding material is completely melted;
s4, the liquid cooling mold (4) is pushed to the fixed template (5) by the hydraulic oil cylinder A (12), so that the liquid cooling mold (4) and the fixed template (5) are assembled, a valve at the port of the injection nozzle (6) is opened, the completely molten injection molding material is continuously injected into a mold groove between the liquid cooling mold (4) and the fixed template (5) by the extrusion molding screw (31), the extrusion molding screw (31) stops rotating after the mold groove is filled with the injection molding material, the valve at the discharge port of the injection nozzle (6) is closed, and the injection molding material is stopped being injected into the mold groove;
s5, a water pump (18) conveys cold water in a water tank (17) to a cooling guide pipe (23) in a liquid cooling mold (4), after an injection molding material in the mold is cooled, a push shaft of a hydraulic oil cylinder A (12) is retracted, the liquid cooling mold (4) and a fixed template (5) are separated, then a push shaft of a hydraulic oil cylinder B (29) is pushed out, a waterproof firewall of the automobile air conditioner formed in the liquid cooling mold (4) is pushed out, and injection molding of the waterproof firewall of the automobile air conditioner is completed.
