PROBLEM TO BE SOLVED: To provide a preplasticization type injection molding machine which prevents stagnation or the like of a molten resin and can deal with variably a variety of injection volumes by one unit. SOLUTION: This preplasticization type injection molding machine 100 is equipped with a plurality of plasticizing devices 11, 12 and 13, a plurality of injection devices 1, 2 and 3, a plurality of first distributors 21, 22 and 23 which are provided respectively between the individual plasticating devices 11, 12 and 13 and the individual injection devices 1, 2 and 3 communicating with each other and make selectable the lead-out of a molten resin into the injection devices 1, 2 and 3 and the lead-out thereof in the direction of one nozzle 5 from the injection devices 1, 2 and 3, a second distributor 4 which is provided between the injection devices 1, 2 and 3 and the nozzle 5 and makes selectable the lead-out of the molten resin injected from one or two or more injection devices 1, 2 and 3, into the nozzle 5, and the nozzle 5. This preplasticization type injection molding machine 100 is so constituted that the plasticizing devices 11, 12 and 13 and/or the injection devices 1, 2 and 3 are selected arbitrarily according to the injection volume of the molten resin and the resin is injected into a mold from the nozzle 5.
