PURPOSE:To sharply improve an operating efficiency of a rotary mold, by a method wherein a cycle time of a process is appropriately selected so that, when one rotary mold is in an centrifugal molding process, the other rotary mold is brought into a process to remove a molded product. CONSTITUTION:Resin and catalyst are supplied to a molding truck 2, and roving and sand are supplied to the molding truck 2 from a roving yarn guide rod 24 and a belt conveyor 32, respectively. After the supply, the roving is crushed in the form of tow, is adjusted into a state that it can be molded, and then, it is fed to a material feed part 39 at a forward end of a rod body 38 through the inside of said rod body. When an inner mold is inserted into a rotary mold 13a. If the molding truck 2 is caused to approach the rotary mold, the material feed part 39 at the forward end of the rod body 38 is also inserted into the inner mold in the rotary mold 13a, a molding material is fed to the inside of the inner mold. Then, a molded product is removed from a rotary mold 13b after the mold 13a is moved to the positon of the mold 13b. |
