Claims (1)
端流路を開閉する弁体と、該弁体を前記先端流路
を閉成する方向に付勢すると共に、その付勢力を
成形用樹脂の流動時の上昇した内部圧力により前
記弁体が開成される大きさに設定した付勢手段と
を備えた開閉弁をホツトランナーノズルの流路に
設けたことを特徴とする糸引き防止構造を備えた
ホツトランナーノズル。 A valve body that opens and closes a tip flow path of a hot runner nozzle that communicates with the sprue, and a valve body that biases the valve body in a direction to close the tip flow path, and applies the biasing force to the rising force when the molding resin flows. 1. A hot runner nozzle with a stringing prevention structure, characterized in that an on-off valve is provided in a flow path of the hot runner nozzle and includes a biasing means set to a size such that the valve body is opened by internal pressure.
