Abstract
The present invention provides a die assembly for molding a resin-made insert having a sleeve that is inserted into an intake port of an internal combustion engine. Each sleeve has one inlet and two outlets. The die assembly includes an inner die and an outer die. The inner die includes an inlet side part and an outlet side part. The inlet side part and the outlet side part mold an inner peripheral surface of the sleeve in an assembled state, and are removed in mutually opposite directions. By means of this assembly, a sleeve having a complicated structure and shape can be molded easily.
