Problems solved by technology
However, in the actual operation process, the assembly of the injection nozzle is difficult, the processing is complicated, and the constant temperature of the flowable material ejected from the injection molding machine cannot be guaranteed. The thermal insulation performance of the injection nozzle is poor, resulting in the molten medium being ejected from the injection nozzle. When the fluidity becomes poor, it affects the injection molding use of the injection molding machine

The invention discloses an injection nozzle for an injection molding machine. The injection nozzle includes an assembling joint, a heat insulating cylinder, a nozzle shell, a nozzle head, a heat preservation inner cylinder and an injection spraying pipe. The interior of the heat insulating cylinder is provided with the heat preservation inner cylinder. The interior of the heat preservation inner cylinder is vertically provided with the injection nozzle. The top of the heat insulating cylinder is provided with an upper cover shell. The top of the injection spraying pipe penetrates through the upper cover shell to be connected with the assembling joint. The bottom of the heat preservation inner cylinder is connected with the nozzle shell. A heat conduction oil cavity is defined by the nozzleshell and the interior of the heat preservation inner cylinder. The nozzle head is installed in the middle of the bottom end of the nozzle shell. The nozzle head is connected with the injection spraying pipe. A molten injection channel of the interior of the injection spraying pipe communicates with the nozzle head. The assembling joint makes the injection spraying pipe be installed on the injection molding machine, then a heater heats heat conduction oil in the heat conduction oil cavity to ensure that an injection raw material flowing through the molten injection channel is in a molten state and is sprayed out of the nozzle head to achieve injection molding. The overall structure is stable and firm, assembly is convenient, the sealing and heat insulation properties are good, and the injection nozzle is beneficial to be used for injection molding.
Description
Technical field [0001] The invention relates to the technical field of injection molding, in particular to an injection nozzle for an injection molding machine. Background technique [0002] The molding or casting process can obtain parts of the same size in large quantities, so it plays an important role in the field of manufacturing. The development and growth of the automobile industry is inseparable from the development of the molding process. Since the automobile industry needs to manufacture parts of the same specification in large quantities, it relies heavily on the molding process. At present, injection molded parts are widely used in auto parts, especially interior parts. [0003] Injection nozzles are widely used. However, in the actual operation process, the injection nozzle is difficult to assemble, the processing and production are highly complicated, and the constant temperature of the flowable substance ejected by the injection molding machine cannot be guaranteed...
