PROBLEM TO BE SOLVED: To provide an apparatus having simple mechanisms capable of producing a stick-shaped molding material usable as a tight stopper in a plunger-type injection molding apparatus.SOLUTION: A molding part 55 provided with a plurality of cavity parts 59 extending in the axial direction and opened at both ends in the axial direction are closed with closing parts 65 and 71. On the side of the closing part 65, a supply hole communicating with a cylinder 29, into which a screw is inserted, supplying a molten resin is formed. In the closing parts 65 and 71, respectively, an insertion hole 69 for a plunger 47 of an electric actuator and a discharge hole 73 are formed so as to be mutually opposite. A molten resin is injected in order into individual cavity parts 59 while the molding part 55 is rotated; a plunger 47 is inserted into a cavity part 59 containing a molding M having been solidified after a time lapse from the injection; and the molding M is discharged from the discharge hole 73. The rotation of the molding part 55 thus delivers moldings M in order, from the cavity parts 59. |
