Abstract
PURPOSE: To obtain a molded product without sink in a short time molding by reducing the thicknesses of a resin injecting port and an air exhausting port of the casting mold, and specifying the internal diameters thereof.
CONSTITUTION: The resin injecting port 2 and the air exhausting port 3 are protruded and formed in the upper part of the mold 1. The thicknesses of the resin injecting port 2 and the air exhausting port 3 are thinner than that of main body of the mold 1, and the internal diameters thereof are 10mm or less. Thermosetting resin composition is injected in said casting mold 1, and the thermosetting resin composition is hardened at the temperature which is higher than that of the injected thermosetting composition and that of the mold 1 by 30°C or more. After the mold is inputted in a heating furnace, the parts of the resin input port 2 and the air exhausting port 3 are quickly hardened because of the thin thickness. Therefore the contraction by setting can be compensated so the product without sink can be obtained.
