Beschreibung
Zusammenfassung:	The invention discloses an injection molding device which comprises a mold, an injection molding nozzle core and a valve needle assembly. A nozzle core matching groove is formed in the top of the mold, an injection molding hole communicated with a mold cavity is formed in the bottom of the nozzle core matching groove, and the lower portion of the injection molding nozzle core is assembled in the nozzle core matching groove with an assembly gap therebetween. An obliquely downward discharging hole is formed in the side wall of the injection molding nozzle core, the lower port of the discharging hole is connected to the upper part of the assembly gap, and the injection molding hole is connected to the lower part of the assembly gap; a valve needle through hole is axially formed in the center of the bottom in the injection molding nozzle core, and a valve needle of the valve needle assembly is controlled to block or open the injection molding hole through the valve needle through hole. According to the invention,
