Abstract: An air conditioner outlet vent device in which one of a blade and a housing is molded as a primary molding having a shaft hole by primary injection using a first synthetic resin, the other is molded, within a secondary mold die where the primary molding has been set, as a secondary molding having a support shaft by secondary injection using a second synthetic resin so that the shaft hole and the support shaft are fitted together at the same time as they are molded, thereby enabling the blade to pivot within the housing. The first and second synthetic resins are of the same synthetic resin system, and an additive for suppressing shrinkage in cooling and solidifying it after injection molding is added to the first synthetic resin so that the percentage mold shrinkage of the shaft hole becomes smaller than that of the support shaft.

Abstract: A resin compound for a molding die, a molding die made of the resin compound, and a molding method using the molding die are disclosed. The resin compound includes thermoplastic resin, inorganic fiber reinforcing material and inorganic particle filler, has a flexural strength of 1000 kgf/cm.sub.2 or more and a modulus of elasticity in bending of 70000 kgf/cm.sup.2 or more, and allows machining. A deflection temperature under flexural load of the compound may be 180.degree. C. or more. From this compound, it is possible to provide a core, a cavity block or the like of molding dies which can be accurately finished by machining finishing with a low cost and within a short term, have durability and allows recycling. The molding dies can be applied to various molding methods, and provide accurate molded products with a low cost.
