A double-layer flow guide accumulator die head device for a blow molding machine belongs to the technical field of blow molding machinery. It comprises a driving mechanism; an accumulator cylinder with an accumulator cavity and an accumulator cover at the upper part; a die sleeve mechanism connected to the accumulator cylinder; an accumulator core fixedly connected to the accumulator cover; a die mechanism connected to both the central pull rod and the die guide connecting mechanism; and a pushing ejector fixing disc arranged in the accumulator cavity. It is characterized by further comprising a plastic melt double-layer flow guide mechanism arranged in the accumulator cavity; a pair of guide pipes are inserted into the accumulator cover, a guide pipe chute is arranged in the middle of each guide pipe, a feed pipe is arranged in each guide pipe cavity, and plastic melt inlet holes are arranged on the side wall of the accumulator cover; feed pipe fixing holes are arranged on the pushing ejector fixing disc, and the lower ends of the feed pipes are fixed to the pushing ejector fixing disc. It simplifies the structure of the accumulator core, ensures the quality of blow-molded hollow plastic containers, and improves the working efficiency of the blow molding machine.
