The present invention relates to an injector nozzle for injecting a melted synthetic resin into a molding frame, and in particular, to an injector nozzle capable of easily controlling the elastic force supporting the nozzle in correspondence to changes in injection pressure. The injector nozzle according to the present invention in order to achieve the purpose comprises a body having a supply path formed therein so that a melted synthetic resin supplied from one side can flow to the other side; an elastomer mounted on the outer periphery of the body; an elastic force control unit movable to the longitudinal direction of the body and pressing the elastomer; a key delivering the elastic force of the elastomer to a needle positioned inside the body; and a nozzle cap mounted on the other end of the body and having a supply hole so that the melted synthetic resin moved to the other side through the supply path of the body can be discharged to outside, wherein the supply hole is open/closed by the movement of the needle. |
