Abstract

PURPOSE: To produce a mold easily and at a low cost, by vacuum-molding a plastic resin sheet by means of a convex prototype, by placing a reinforcing sheet on the molded product situated on the convex prototype to produce a convex former, and by filling the former with a material, such as polyester resin, cement, etc., to form a convex resin mold.
CONSTITUTION: A plastic resin sheet 2 is vacuum-molded by the use of a convex prototype 1 made of a wood, which serves as a vacuum-molding former, to form a molded product 3. A reinforcing sheet 4 is then adhered to the vacuum-molded product 3 after the product 3 is colled enough on the prototype 1, the work being placed on a support stand 6 so as to serve as a former 5 after it is removed from the convex prototype 1. A core 7 is set on the former 5 such that a given space is provided between the convex former 5 and the core 7, the space being filled with resins such as polyester or epoxy, plaster of Paris, cement and the like 8 to form a convex resin mold 9. With the convex resin mold 9 placed on a mold frame 10 such that a given space is provided between the two parts, a convex resin mold 12 may also be formed easily by filling the space with resins 11.
