PURPOSE: A molding method for a hollow-shaped product using rotation and a molding device therefor are provided to efficiently use a work space by simplifying the molding device. CONSTITUTION: A molding method for a hollow-shaped product using rotation is as follows. A molding unit is divided into first and second molding units(15-1,15-2,25-1,25-2). After a molded product is removed, the side surface of the second molding unit is coupled to the first molding unit. When the first molding unit having a firstly molded product is coupled to the second molding unit, resin is simultaneously injected into the first and second molding units and is injection-molded. After the product is removed from the second molding unit, the second molding unit is moved to the first molding unit, and the first molding unit having the firstly molded product is coupled to the moved second molding unit. |
