Abstract
PURPOSE:To reduce man-hours drastically and to miniaturize the whole of manufacturing facilities, by method wherein a partition wall dividing a gas passage and resonant chamber is molded by a rib protruding from the inside of a mold and blow molding of a tubular body and the partition wall is performed. CONSTITUTION:Simultaneously with mold clamping due to a top and bottom forces 41, 42 a slide rib 43 is projected, a state of which is kept on for a short period of time and blow molding is performed. Then the slide rib 43 is held within an upper blow molding mold 41 prior to cure of resin and a vacuum is drawn through a space where the slide rib 43 gas been present. A right and left walls of a partition wall part 23a are stuck close to each other through drawing the vacuum and molded into a thin wall form. With this adhesion, an opening part is eliminated from the top of a tubular body and the top becomes a smooth plane where there is no molding mark due to the rib. As the partition wall is molded at a time by the same process practically as the molding of the tubular body protruding within the inside of the mold like this, very small man-hours will do.
