Claims (1)
ンダ内に回転可能に設けたスクリユーにより、溶
融した原料を先端のノズルから金型内に注入して
成形する射出成形機において、該ホツパー口の原
料冷却を、該射出成形機を作動する油圧シリンダ
用のタンクを共用する油圧管路により行うことを
特徴とする射出成形機のホツパー口の冷却装置。 In an injection molding machine that receives raw material in a hopper into a cylinder and injects the molten raw material into a mold from a nozzle at the tip using a screw rotatably installed in the cylinder, the raw material at the hopper mouth is cooled. A cooling device for a hopper opening of an injection molding machine, characterized in that the above is performed by a hydraulic pipe line that shares a tank for a hydraulic cylinder that operates the injection molding machine.
