AN ASSEMBLED NOZZLE WITH A PLURAL OF RESIN PASSAGES FOR HOT RUNNER SYSTEM OF INJECTION MOULD

摘要

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. The valve pin passage, the straight resin passages, and the valve pin hole are connected with each other.
