<p>Disclosed is an injection molding die having a fluid flow path through which a fluid such as steam for heating a die, or a coolant flows. The disclosed injection molding die comprises an upper core and a lower core which together form a cavity corresponding to the shape of an injection-molded product, wherein at least one of the upper core and the lower core includes an external block formed with a cavity face for limiting a cavity and an insertion groove on the opposite side surface of the cavity face; and an internal block inserted into the insertion groove. A dead-end face of the insertion groove and the internal block facing the dead-end face are curved faces as facing each other to be closely adhered, and the internal block is formed with at least one curved channel which has an intaglio pattern and extends from the curved face. In addition, a curved fluid flow path in which at least one fluid of steam and coolant flows by at least one of the curved channel and the dead-end face is formed on the injection molding die.</p> |
