PROBLEM TO BE SOLVED: To provide a vacuum molding technique capable of reusing a film material over a plurality of times of vacuum molding. SOLUTION: The vacuum molding device 10 includes: a preform mold (molding mold) 12 having a molding face 22 for molding carbon fiber (raw material) 50 into a product having a prescribed shape; and a bag film (film material) 30 of air-tightly covering the molding face 22 of the preform mold 12. A fastener part 40 which is opened and closed so as to permit taking-out and in of the carbon fiber 50 before and after the molding between the molding face 22 and the bag film 30 is formed on the bag film 30. Therefore, when taking-out and in the carbon fiber 50 between the molding face 22 and the bag film 30, the carbon fiber 50 can be taken-out and in through the fastener part 40 and there is no necessity for removing the bag film 30 joined to the preform mold 12. As the result, the bag film 30 can be reused over a plurality of times of vacuum molding. COPYRIGHT: (C)2010,JPO&INPIT |
