    • An injection-molding metal mold used for injection-molding a body having a precision portion which is formed at high precision includes a molding cavity in which a precision molding portion for molding the precision portion is set to have a heat conductivity higher than that of general molding portions for molding other portions of the body and shortens the time required by a molding cycle to mold a body having a precision portion. Also, an injection-molding metal mold used for injection-molding a body having a precision portion which is formed at high precision includes a molding cavity constituted by a molding member in which a precision molding portion is formed to mold the precision portion and general molding portions for molding other portions. Also provided is an ejector pin, disposed adjacent to the molding member to partially constitute the cavity; for ejecting a molded body; and a cooling unit for cooling the molding member through the ejector pin. This injection-molding metal mold shortens the time required by a molding cycle to mold a body having a precision portion.
