PURPOSE: A dual-valve pin nozzle device for a hot runner system of an injection forming mold is provided to prevent the interference of a valve pin and a melting resin by forming a valve pin passage and a resin pin passage in a nozzle separately. CONSTITUTION: A dual-valve pin nozzle device for a hot runner system of an injection forming mold comprises a fixed valve pin(110), a moving valve pin(120), a valve pin driving unit(100), and a nozzle(200). The fixed valve pin is coupled with the mold of a fixed part and projected to the inside of a cavity(400). The fixed valve pin is inserted in the longitudinal hole of the moving valve pin. The moving valve pin is moved along the fixed valve pin. The valve pin driving unit moves the moving valve pin up and down. The nozzle comprises a valve pin passage(212) and a resin passage(213). The fixed valve pin and the moving valve pin are inserted in the valve pin passage. The melting resin is supplied into the cavity.
