Circulating injection molding machine

The invention discloses a circulating injection molding machine. The circulating injection molding machine comprises a main body shell, a plastic containing groove is formed in the top of one side ofthe main body shell, a main longitudinal flowing hole is formed in the bottom of the plastic containing groove, a funnel space is formed in the bottom of the main longitudinal flowing hole, and an auxiliary longitudinal flowing hole is formed in the bottom of the funnel space; and the main body shell is provided with an eddy current heating mechanism on the annular side surface of the auxiliary longitudinal flow hole, and the bottom of the auxiliary longitudinal flow hole is provided with a transverse plastic feeding hole. According to the circulating injection molding machine, normal raw material melting and injection functions can be achieved, when raw material injection needs to be delayed due to external factors, molten plastic can flow in an internal circulation mode through the raw material pushing effect of
