PURPOSE: A multiple passage-assembled nozzle having a plurality of resin passages for a hot runner system of an injection forming mold is provided to inject high quantity of resin with short time by forming a plurality of melting resin passage in a nozzle body. CONSTITUTION: A nozzle(100) comprises a nozzle body(110) and a nozzle heat(120). The nozzle head is assembled and coupled in the bottom part of the nozzle body. A straight valve pin passage(112) and plurality of straight resin passages(113) are formed inside the nozzle body. A nozzle pin is moved up and down in the valve pin passage by forming the passage in longitudinal direction. A plurality of straight resin passages are formed in the longitudinal direction of the nozzle body. A valve pin hole is formed to have same center point with the straight valve pin passage.
