PROBLEM TO BE SOLVED: To provide an injection molding machine having a recycled material comminuting function for sending a runner and the like to be discharged after injection molding without comminuting as it is into a heating cylinder of the machine as the recycled material. SOLUTION: The injection molding machine 20 comprises a recycled material introducing port 33 provided in a heating cylinder 23 for melting a molding material to supply it to a mold to introduce a recycled material 35 to the cylinder 23. Thus, the machine 20 comminutes the material 35 by a rotation of a screw 22 in the cylinder 23 and an opening edge of the port 33, melts it together with a virginal material 24, and fills in a mold 27. The machine 20 can provide a recycled material transfer unit for transferring the material 35 to the cylinder 23 and introducing it thereinto. |
