PURPOSE: A hot runner valve device for an injection molding machine is provided to easily control the supply of resin injected to a cavity of a mold because the end of a lifting pin is positioned inside a nozzle or contacts with the mold while ascending or descending the lifting pin. CONSTITUTION: A hot runner valve device(1) for an injection molding machine comprises a manifold(10) and a nozzle(20). The manifold forms a resin path(10a). The nozzle is connected to one side of the manifold and guides received resin to a cavity(c) of a mold(m). A heater(23) is wound on the outer circumference of the nozzle. The nozzle comprises a body(21) and a lifting pin(30) having a flow control tip(32). |
