BLOW-MOLDING METHOD AND A BLOW-MOLDING DEVICE FOR MANUFACTURING VARIOUS PLASTIC PRODUCTS SUCH AS HOLLOW CONTAINERS INCLUDING A FUEL TANK AND A CONTAINER

摘要

PURPOSE: A blow-molding method and a blow-molding device are provided to prevent breakage or lowering of rigidity of the product by blow-molding the parison with the optimal elongation rate, and to improve working efficiency by moving the mold segment along the inclined shaft. CONSTITUTION: A mold closer(18) is opposed to a mold closer(20), and parison is placed between the opposed mold closers. The mold closers are moved forward and contacted to each other. The parison is placed between the mold closers, and the mold closer around the parison is closed by moving the mold closer forward along two or more axes. The article is produced by blow-molding the parison, and gas is injected to the parison. The mold closers are moved backward along each axis, and the product is separated from the parison. The mold closer is moved between the opening position and the closing position, and the opposed mold closers are contacted to each other.
