The hot runner system equipped with the turbulence generating member of the present invention includes a reinforcement plate 104 fixed to the upper side of the cavity plate 102 and into which a nozzle 120 for supplying resin to the gate 112 is inserted, A manifold 130 connected to the nozzle locator 150 to form a manifold flow path 132 through which the resin flows, a manifold 130 connected to the nozzle locator 150, An insulation pad 140 which is connected to the manifold 130 and is connected to the manifold flow path 132 and is connected to the injection port 140 through which the resin is injected, And a turbulent flow generating member 200 provided in the manifold flow path 132 to improve the turbulent flowability of the resin flowing through the nozzle locator 150. [

The manifold 130 is divided into upper and lower manifolds 130a and 130b. The upper and lower manifolds 130a and 130b are connected to the manifold 130, Respectively.

The upper manifold 130a further includes a connection hole communicating with the nozzle locator 150 to supply resin and the lower manifold 130b is connected to the nozzle 120 to supply the resin to the nozzle 120 The resin supply holes 134 can be formed.

The manifold 130 is formed such that a manifold flow path 132 serving as a runner that uniformly distributes the resin supplied from the nozzle locator 150 and supplies the resin to the nozzle 120 is branched.
