A nozzle for an injection-molding device comprises a needle head(100), a needle assembly, and a nozzle cap(300). The needle head includes an expanded hole(110) and a female screw(111). The expanded hole is formed inside, and the female screw is positioned at the expanded hole. The needle assembly includes a needle body(220), a needle(210), a spring(230), and a spring body(240). The needle body combines a rear male screw(224) with the female screw of the needle head, and has a plurality of resin solution supply holes(222) at a longitudinal direction thereof. The needle is inserted into a center portion of the needle body. The spring supports the needle. The spring body prevents the spring from being separated. The nozzle cap is combined with a front male screw of the needle body and formed with a nozzle hole(310) at the center portion of a front side thereof. The needle body includes a sill(221a) at an inner center hole(221). The needle includes an expansion unit at the middle portion thereof to be hanged. The spring body is screw-jointed with a rear side of the needle body to prevent the spring from being separated.
