The invention provides a fuel tank manufacturing device and a fuel tank manufacturing method, which can reduce the production cost of manufacturing a fuel tank with a rib-shaped part and shorten the production cycle. An apparatus for manufacturing a fuel tank having a molding die and a cooling die, the apparatus being characterized in that the molding die has a ridge portion on a molding surface, a primary molded article is molded while the ridge-shaped portion (21) is molded to have a recessed portion on an outer surface, and the cooling die (40) flattens the ridge-shaped portion (21) by a cooling blow pressure and cools the ridge-shaped portion (21) by a cooling blow pressure. And cooling the primary molded article while deforming the primary molded article into the rib-shaped part (3).
本发明提供一种燃料箱的制造装置以及燃料箱的制造方法,能够降低制造具有肋状部的燃料箱的生产成本、缩短生产周期。具有成形模具和冷却模具的燃料箱的制造装置,其特征在于:成形模具在成形面上具有凸条部,将凸棱形状部(21)成形为在外表面上具有凹部的同时成形一次成形品,而冷却模具(40)在通过冷却吹塑压力将凸棱形状部(21)压扁,使其变形为肋状部(3)的同时冷却一次成形品。
