摘要

The present invention relates to an injection mold having a PET dust discharging system. The injection mold of the present invention comprises the following: an upper fixing plate mounted with a piston assembly for actuating a valve pin; a lower fixing plate mounted with a nozzle for discharging a resin by the valve pin; a manifold supplying the resin to perform injection molding; and a dust removing panel including a dust receiving groove formed between the upper fixing plate and the lower fixing plate to receive a residual resin to prevent the accumulation of the resin, an air injection hole connected to one side of the dust receiving groove for injecting air, and a dust discharging groove connected to the other side of the dust receiving groove for discharging the dust contained in the air.
