ASSEMBLY MOLDING AIR BLOWOFF PORT AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To independently turn a wind direction control blade by forming the body of a casing of a resin material which is nonadhesive to a resin material used for the wind direction control blade and also has a melting point mutually different from the melting point of the resin material used for the wind direction control blade. SOLUTION: In the case of forming a horizontal blade 3 and a vertical blade 5 by using a two-color injection molding machine, the body 11 of a casing is inserted into a second and third assembly molding dies fitted in the mold clamping device of the two-color injection molding machine. A second and a third resin materials being the horizontal and the vertical blades-molding resin materials are injected into the space part formed in the molding dies. A resin material used for a wind direction control blade is adopted which is nonadhesive to the first resin material used for the body 11 of the casing as the second and the third resin materials and has a melting point lower than the melting point of the first resin material.
