Beschreibung
Zusammenfassung:	The utility model relates to the field of injection molding machine and in particular relates to an injection mechanism of an injection molding machine. The injection mechanism of the injection molding machine comprises an injection oil cylinder, an injection barrel, a before injection barrel and a nozzle, the injection oil cylinder is connected with an injection piston, one end of the before injection barrel is connected to the injection barrel; the injection mechanism further comprises a nozzle transition body and a nozzle oil cylinder, the upper part of one end of the nozzle transition body is connected with the before injection barrel while the lower part of the other end is connected with the nozzle, an oblique passage is formed in the nozzle transition body, two ends of the oblique passage are respectively connected with the before injection barrel and the nozzle, the nozzle piston is arranged in the nozzle oil cylinder, the nozzle piston is connected with the nozzle valve core in axial direction, and the nozzle valve core is arranged in the nozzle. The injection mechanism of the injection molding machine raises the sealing performance between the nozzle and the die cavity, effectively prevents the backflow and material leakage and has compact structure.
