A hot rubber valve system for an injection molding machine is provided to reduce vibration and damage to components by lifting up a valve pin through rotation of a rotator. A hot rubber valve system(1) for an injection molding machine comprises a manifold(3), a nozzle(5), a valve pin(7) installed in the nozzle to open/close a gate, and a driving unit(10) for moving the valve pin up and down. The manifold is made from a metal and has a plate shape. A resin feeding port is formed at one side of the manifold and a resin channel(3p) is branched in the manifold. A heating wire is provided at top and bottom surfaces of the manifold to prevent resin from being solidified. The nozzle is provided at a lower portion of the nozzle to supply resin to a mold.
