Abstract
A temperature adjustment mechanism for use in an injection molding machine that shortens a molding cycle time while preventing the occurrence of a stranding phenomenon in an optimum manner. A passage includes an opening arranged near an outer surface of an outlet of an injection nozzle for an injection molding machine. A supply control unit supplies the passage with at least one of cooling air and heating air to selectively eject the cooling medium, the heating medium, and a mixture of the cooling medium and the heating medium near the outer surface of the outlet.
Claims20
A temperature adjustment mechanism for use in an injection molding machine including an injection nozzle for injecting resin material, the temperature adjustment mechanism comprising:
- a medium circulation unit which selectively circulates a cooling medium and a heating medium in the medium circulation unit;
- and
- a supply control unit which controls supply of the cooling medium and the heating medium into the medium circulation unit so that the cooling medium and the heating medium are selectively ejected from the medium circulation unit,
- wherein the medium circulation unit includes an opening for ejection, the opening to allow circulation of said mediums around the injection nozzle.
A temperature adjustment mechanism for use in an injection molding machine including an injection nozzle for injecting a resin material, the temperature adjustment mechanism comprising:
- a pipe-shaped medium circulation unit which circulates a cooling medium that cools the resin material in the injection nozzle and which partially extends through the injection nozzle;
- and
- a supply control unit which controls supply of the cooling medium to the medium circulation unit,
- wherein the medium circulation unit includes an opening for ejection, the opening to allow circulation of said mediums around of the injection nozzle.
