[0001] The invention relates to the technical field of injection molding equipment, and in particular to a multi-station automatic and efficient injection molding equipment. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. Among them, the injection mold is installed in the injection molding machine, and according to the characteristics of the product, the injection mold needs to be temperature controlled. Generally, the water inlet pipe and the return pipe are connected. However, when the water inlet pipe and the return pipe are connected, generally, they are directly connected to the main pipe through the mold temperature controller, and then a group of water inlet pipes are connected to the injection mold through the mold temperature controller, and a group of water outlet pipes are connected to the injection mold through the mold temperature controller, and the pipelines on the injection mold are connected to form a complete circuit.

[0003] Automobile instrumentation is composed of various instruments and indicators, especially warning lights and alarms for drivers, which provide the driver with the required information on automobile operating parameters. Automobile instrumentation is installed and integrated on the automobile dashboard. At present, the existing automobile dashboard is generally formed by injection molding. The staff first heats the plastic, and then applies high pressure to the heated molten plastic to make it ejected and fill the mold cavity and solidify into shape. However, after the injection molding of the automobile instrumentation is completed, the automobile instrumentation needs to be cooled before it can be formed. Therefore, it needs to be placed for a period of time and the molded dashboard can be taken out after it cools down. During this period, injection molding cannot be continued, which increases the time required for automobile instrumentation production, thereby reducing the efficiency of automobile instrumentation injection molding. Summary of the invention

[0004] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art and to provide a multi-station automatic and efficient injection molding device, which can solve the problem that automobile instruments need to be cooled before they can be molded, so they need to be placed for a period of time until the molded instrument panel is cooled before they can be taken out, and injection molding cannot be continued during this period, which increases the time required for automobile instrument production, thereby reducing the efficiency of automobile instrument injection molding.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a multi-station automatic and efficient injection molding equipment, comprising a mounting base and a product cooling device; a servo motor is fixedly mounted on the top of the mounting base, a rotating shaft is fixedly connected to the output end of the servo motor, and a disc is fixedly connected to the upper end of the rotating shaft; the product cooling device comprises a blower, an exhaust pipe and a conical exhaust cylinder, the blower is fixedly mounted on the top of the mounting base, the lower end of the exhaust pipe is fixedly mounted on the exhaust end of the blower, the conical exhaust cylinder is fixedly connected to the upper end of the exhaust pipe, and the conical exhaust cylinder is fixedly mounted on the top of the disc.

[0010] Preferably, an injection molding machine is fixedly installed inside the mounting plate, a material delivery hose is fixedly connected to the output end of the injection molding machine, and one end of the material delivery hose away from the injection molding machine is fixedly installed inside the injection hole.

[0011] Preferably, the interior of the disc is circular and equidistantly slidably connected with four sliding rods, and the upper ends of the four sliding rods are respectively fixedly connected to the bottoms of four demoulding push plates.
