Injection molding nozzle excess material cleaning mechanism and injection molding machine

Abstract

The utility model relates to the technical field of injection molds, in particular to an injection molding nozzle excess material cleaning mechanism and an injection molding machine. The device comprises a bottom frame, an injection molding nozzle, a cleaning assembly and a material conveying mechanism, the cleaning assembly comprises a plurality of air bags and communicating pipes which are annularly arranged on the injection molding nozzle, a plurality of baffle plates which are annularly arranged on the injection molding nozzle, and an air inlet pipe and an exhaust pipe which are communicated with the air bags and the communicating pipes; the multiple shielding plates are connected with the multiple air bags in a one-to-one correspondence mode, air outlet holes are formed in the two ends of the multiple air bags, a forming assembly, a driving frame and an injection molding frame are arranged on the bottom frame, a heating sleeve is arranged on the injection molding frame, and the injection molding nozzle communicates with the injection molding frame. The material conveying mechanism comprises a driving assembly arranged on the driving frame and a material conveying assembly arranged on the injection molding frame. According to the utility model, the baffle plate is lifted up to destroy a hardened excess material structure, and excess materials are sprayed to a position which does not affect next injection molding processing through the plurality of air bags.
