PURPOSE:To charge a cleaning resin to details of a complicated molding die to clean the mold and to improve a workability by a method wherein a plurality of cleaning resins are disposed on at least one surface of a sheet- or tape-form substrate in accordance with the position of a mold cavity to be formed integrally with the substrate. CONSTITUTION:A plurality of cleaning resins are disposed on at least one surface of a sheet- or tape-form substrate in accordance with the position of a mold cavity to be formed integrally with the substrate. As the substrate, all materials having a temperature resistance as high as a curing temperature of the resin and a predetermined strength can be used, and paper, glass, cloth, metal, plastic film, and the like can be used. As an example of production methods, a plurality of through holes 4 are formed in the substrate 1 for securely bonding the cleaning resins 2 to the substrate 1, and a cleaning material 3 is produced by integrally forming the cleaning resins 2 on the both surfaces of the substrate. This is clamped between heated molds 5 under heat and pressure. After the cleaning resins are cured, the cleaning resins are removed together with the substrate for cleaning the molds. |
