Abstract
PURPOSE: To obtain a molded urethane product of a high dimension accuracy by fixing a silicone rubber mold to a flask guide and a mold bottom plate with hard urethane foam, whereby the silicone rubber mold is never expanded by the reaction heat generated during the foaming and hardening of a urethane product.
CONSTITUTION: A die 2 is fixed on a die support 1, and a flask guide 3 is set on the die support 1 such as to surround the die 2. Silicone rubber is poured onto the whole of the upper surface of the die 2 to form a silicone rubber mold 4 on the die 2. Polyurethane is coated on the whole of the upper surface of the silicone rubber mold 4, and a mold bottom plate 5 is placed over the die 2 to be fastened to the flask guide 3 with bolts. The polyurethane is then heated to be foamed and hardened so that a space 6 between the mold bottom plate 5 and silicone rubber mold 4 is filled with hard urethane foam 7. During this foaming operation, air in the space 6 is discharged through small air vents 13. When the polyurethane has been foamed and hardened, the die support 1 is removed, and the die 2 is also removed from the silicone rubber mold 4. As a result, a silicone rubber mold for urethene products is obtained.
