Injection nozzle structure for injection molding machine

Abstract

The utility model discloses an injection nozzle structure for an injection molding machine, which comprises a charging barrel, a plurality of groups of material guide nozzles are welded and mounted at one end of the charging barrel, material guide ports are formed in the material guide nozzles in a penetrating manner, a nozzle mechanism is mounted at one end of the charging barrel, and a heat storage cavity is arranged at one end of the nozzle mechanism. And a screen frame plate is installed in the nozzle mechanism and located between the heat storage cavities, multiple sets of butt-joint nozzles corresponding to the material guide nozzles in position are installed on the nozzle mechanism, and threaded pipes are installed in the butt-joint nozzles in a threaded mode. The heat storage cavity increases the size of a material conveying heat preservation environment in the charging barrel, and the situation that materials guided out of the charging barrel directly make contact with air through the material guiding nozzle and the outer wall of the nozzle mechanism to be cooled, and the fluidity of the materials is affected is avoided.
