PROBLEM TO BE SOLVED: To provide a plasticizing feeding apparatus efficiently transporting a greater quantity of plasticized molding materials to a measuring/injection device, and to provide a rotor thereof and an injection molding machine using the same. SOLUTION: The plasticizing feeding apparatus 15 includes: a barrel 24 in which a material flowing-in passage 28 opens in one end face 24F; a rotor 25 which is rotatably driven around the opening of the material flowing-in passage 28 of the barrel 24 and which has an end face 25F that comes in slidable contact with the one end face 24F of the barrel 24; a plurality of spiral grooves 34 which are formed in the end face 25F of the rotor 25 to define a plasticizing passage 30 of the molding materials between the grooves and the one end face 24F of the barrel 24, with the molding materials supplied from the outer end part 34OE in the radial direction, and with the inner end part 34IE in the radial direction communicated respectively with the opening end of the material flowing-in passage 28 of the barrel 24. These spiral grooves 34 are desirably arranged to be point-symmetrical with respect to the rotary center O of the rotor 25. COPYRIGHT: (C)2011,JPO&INPIT |
