STRUCTURE VACUUM MOLD FOR IMPROVING VACUUM EFFICIENCY CHARGING POROUS MATERIAL OR FILLER SPACED APART FROM INNER FACE OF MOLD

摘要

PURPOSE: Structure of a vacuum mold is provided to minimize the costs for operating a vacuuming device and the discharge of air by improving the internal structure of a mold and to improve a vacuum molding product by preparing a desired vacuum in a short time. CONSTITUTION: An outer surface of a body having many air holes(11a) forms a molding face of a product. A forming mold(11) composed of an empty inner space is connected with a vacuuming device(14) to closely form a product on the outer surface of the mold. In such a vacuum mold(10), a porous material(20) is charged in the inner space of the forming mold, or a filler spaced apart from the inner face of the forming mold is inserted to the inner space of the forming mold.
