The invention belongs to the technical field of injection molds and discloses a mold nozzle assembly for injection molding a large plastic part to solve the problem that an existing large plastic parthas air bubbles and is not uniform in texture in the injection molding process. The mold nozzle assembly comprises a plurality of nozzle bodies. Each nozzle body comprises an inner barrel body and anouter barrel body. The outer barrel body is arranged out of the inner barrel body in a sleeving manner and an electric heating wire is arranged between the inner barrel body and the outer barrel body, a first end cover communicating to an injection molding machine and a second end cover in butt joint to the injection mold are separately arranged at two ends of the inner barrel body and the outerbarrel body, a runner is arranged in the inner barrel body, an injector head communicating to the runner is connected to the second end cover, the injector head comprises a first injection pipe and asecond injection pipe arranged in the first injection pipe in a sleeving manner, the end part of the second injection pipe is connected to a nozzle, an annular groove is formed in the first injectionpipe, a nut is arranged in the middle of the annular groove in a sleeving manner, and a threaded section matched with the nut is arranged in the middle section of the second injection pipe.
Description
technical field [0001] The invention belongs to the technical field of injection molds, in particular to a mold nozzle assembly for injection molding large plastic parts. Background technique [0002] Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die-casting method. Injection molding is to make thermoplastic or thermosetting materials into various shapes using plastic molding molds. Plastic products, injection molding is achieved through injection molding machines and molds. [0003] During the injection molding process, the injection molding machine heats and melts the plastic and then pushes it to the nozzle, through which the molten plastic is filled into the cavity of the mold. At the same time, in order to maintain the temperature of the molten plastic in the nozzle and prevent condensation, the n...
