The invention discloses a spiral feeding inner heating injection molding machine. The spiral feeding inner heating injection molding machine comprises a machine frame, an outer barrel, an extrusion head, a feeding device, a rotary motor, an inner barrel and a burner, wherein the inner barrel is of a hollow structure; continuous spiral pieces are arranged on the outer wall of the inner barrel; the right end of the inner barrel is provided with a fire inlet pipe in a communicated mode; the left end of the inner barrel is provided with a fire outlet pipe in a communicated mode; a chain wheel is arranged on the fire inlet pipe and connected with the rotary motor through a chain; the inner barrel is sleeved with the outer barrel; bearings are arranged at the two ends of the outer barrel; the fire inlet pipe and the fire outlet pipe penetrate through the bearings and are rotationally connected with the bearings; the outer barrel is fixedly arranged on the machine frame; the feeding device is arranged at the right end of the outer barrel; the extrusion head is arranged at the left end of the outer barrel and used for extruding and forming a plastic part; the fire inlet pipe of the inner barrel is connected with the burner. The spiral feeding inner heating injection molding machine effectively improves the melting efficiency and the productivity of plastic parts, and reduces the production cost.
