Problems solved by technology

The injection molding machine mainly includes parts such as feeding mechanism, barrel, screw and nozzle; the existing feeding mechanism is mostly a single feeding funnel, which cannot better filter out the iron chips in the plastic raw materials; now Some barrels will lose a lot of heat during the production process, resulting in a waste of energy; the existing screw needs to move as a whole during the injection process, resulting in high energy consumption and greater wear; the existing nozzle There will be salivation when the injection is completed, resulting in contamination of the melt and waste of materials

Abstract

The invention relates to the technical field of injection molding machines, and relates to an injection system of an injection molding machine. The injection system comprises a threaded rod body and a nozzle body. The threaded rod body comprises a threaded rod main body. A threaded rod head is arranged at the left end of the threaded rod main body. The threaded rod head comprises an installation base, a threaded rod head base, a threaded rod head main body and a non-return ring. The nozzle body comprises a nozzle base. A hollow connection sleeve and a nozzle head are sequentially arranged on the left side of the nozzle base. The nozzle head comprises a nozzle head installation base and a nozzle cover. A material injection channel and a slide channel are coaxially arranged on the middle portion of the nozzle base and the middle portion of the nozzle head installation base correspondingly. The two ends of an ejector rod are matched with the material injection channel and the slide channel in a slidable and closed manner. A circular-ring-shaped first exciting winding is arranged on the portion, at the position of the inner side of the hollow connection sleeve, of the left end face of the nozzle base. A circular-ring-shaped second exciting winding is arranged on the portion, at the position of the inner side of the hollow connection sleeve, of the right end face of the nozzle head installation base. An annular iron plate is arranged at the position, located between the first exciting winding and the second exciting winding, on the outer side of the ejector rod. The injection system can well conduct injection on melt.
