用成形ノズル。[Scope of Claim for Utility Model Registration] (1) In the nozzle of an injection molding machine that applies a high shear rate by a rotary valve provided in the nozzle part of the injection molding machine, the hole diameter of the nozzle is brought into contact with the mold from the rotary valve part. For ultra-high molecular weight polyethylene, the nozzle has a tapered shape in which the diameter of the resin flow path becomes thicker toward the tip, and the diameter of the tip of the nozzle hole is smaller than the diameter of the sprue of the mold that comes into contact with the nozzle tip. Molding nozzle. (2) The molded nozzle for ultra-high molecular weight polyethylene according to claim (1), wherein the outer periphery of the nozzle hole is cooled by a water-cooled jacket, an air-cooled jacket, natural cooling, forced air blow cooling, or the like.
