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.

The invention claimed is: 1. 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. 2. The temperature adjustment mechanism according to claim 1, wherein: the medium circulation unit is arranged so as to selectively eject the cooling medium and the heating medium toward an outer surface of the outlet. 3. The temperature adjustment mechanism according to claim 1, wherein: the injection nozzle includes a resin passage which is in communication with the outlet and circulates the resin material; and the medium circulation unit partially extends through the resin passage. 4. The temperature adjustment mechanism according to claim 1, wherein the supply control unit simultaneously supplies the heating medium and the cooling medium into the medium circulation unit so that a mixture of the cooling medium and the heating medium is ejected as the heating medium from the medium circulation unit. 5. The temperature adjustment mechanism according to claim 1, wherein the medium circulation unit includes: a first medium passage which circulates the cooling medium; a second medium passage which circulates the heating medium; and a third medium passage which is in communication with the first medium passage and the second medium passage and which ejects the medium circulated in the third medium passage via the first medium passage and the second medium passage. 6. The temperature adjustment mechanism according to claim 1, wherein the supply control unit continuously changes a supplied amount of each of the cooling medium and the heating medium. 7. The temperature adjustment mechanism according to claim 1, wherein the supply control unit controls the supply of the cooling medium and the heating medium to the medium circulation unit by switching to either one of a supply state and a supply completion state. 8. The temperature adjustment mechanism according to claim 1, wherein the supply control unit controls a supply initiation timing and a supply completion timing of the heating medium using a displacement parameter that is at least one of information related to a molding cycle of the injection molding machine, information related to the resin material, information related to a temperature to which the injection nozzle is heated, information related to a diameter of the outlet, information related to a diameter of a sprue formed in the mold, information related to a length of the sprue, and information related to a molded product formed by the mold. 9. 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. 10. The temperature adjustment mechanism according to claim 9, wherein: the injection nozzle includes a resin passage which is in communication with the outlet and circulates the resin material; and the medium circulation unit is arranged so that the medium circulation unit partially extends through the outlet in a direction intersecting a circulation direction of the resin material circulated in the resin passage. 11. The temperature adjustment mechanism according to claim 10, wherein the medium circulation unit partially extends through a central portion of the resin passage. 12. The temperature adjustment mechanism according to claim 9, wherein the supply control unit controls a supply initiation timing and a supply completion timing of the cooling medium using a displacement parameter that is at least one of information related to a molding cycle of the injection molding machine, information related to the resin material, information related to a temperature to which the injection nozzle is heated, information related to a diameter of the outlet, information related to a diameter of a sprue formed on the mold, information related to a length of the sprue, and information related to a molded product formed using the mold. 13. The temperature adjustment mechanism according to claim 9, wherein the supply control unit supplies a heating medium into the medium circulation unit in addition to the cooling medium and controls supply of the cooling medium and the heating medium into the medium circulation unit. 14. The temperature adjustment mechanism according to claim 2, wherein the supply control unit simultaneously supplies the heating medium and the cooling medium into the medium circulation unit so that a mixture of the cooling medium and the heating medium is ejected as the heating medium from the medium circulation unit. 15. The temperature adjustment mechanism according to claim 2, wherein the medium circulation unit includes: a first medium passage which circulates the cooling medium; a second medium passage which circulates the heating medium; and a third medium passage which is in communication with the first medium passage and the second medium passage and which ejects the medium circulated in the third medium passage via the first medium passage and the second medium passage. 16. The temperature adjustment mechanism according to claim 2, wherein the supply control unit continuously changes a supplied amount of each of the cooling medium and the heating medium. 17. The temperature adjustment mechanism according to claim 2, wherein the supply control unit controls the supply of the cooling medium and the heating medium to the medium circulation unit by switching to either one of a supply state and a supply completion state. 18. The temperature adjustment mechanism according to claim 2, wherein the supply control unit controls a supply initiation timing and a supply completion timing of the heating medium using a displacement parameter that is at least one of information related to a molding cycle of the injection molding machine, information related to the resin material, information related to a temperature to which the injection nozzle is heated, information related to a diameter of the outlet, information related to a diameter of a sprue formed in the mold, information related to a length of the sprue, and information related to a molded product formed by the mold. 19. The temperature adjustment mechanism according to claim 10, wherein the supply control unit controls a supply initiation timing and a supply completion timing of the cooling medium using a displacement parameter that is at least one of information related to a molding cycle of the injection molding machine, information related to the resin material, information related to a temperature to which the injection nozzle is heated, information related to a diameter of the outlet, information related to a diameter of a sprue formed on the mold, information related to a length of the sprue, and information related to a molded product formed using the mold. 20. The temperature adjustment mechanism according to claim 10, wherein the supply control unit supplies a heating medium into the medium circulation unit in addition to the cooling medium and controls supply of the cooling medium and the heating medium into the medium circulation unit.
