A vertical-type injection molding machine comprising a lower fixed mold half (1) mounted on a machine base, an upper movable mold half situated upwardly of said lower fixed mold half (2) in confronting relationship therewith, and a material reservoir (5) for storing a cleaning material and a various kinds of molding materials individually. The material reservoir (5) has a switching means (5a) for switching one kind of molding material over another. The injectin molding machine also comprises an injector (3) having a nozzle (3a), an injection cylinder (3b), and a molding material supply unit (3c) connected to the switching means (5a) via a material supply pipe (4), means (6) for opening and closing a tip (3a') of said nozzle (3a) during the switching of the molding materials, and a discharged material receiving device (8) reciprocatingly movable between a position right under the nozzle tip (3a') and a position right above a material discharge portion (7) on the side of said upper movable mold half (2) and adapted to be inverted by 180 DEG . <IMAGE> |
