PURPOSE:To release a closely adhered article without generating damage and a crack in a plastic molded article and damaging a glass mold, by injecting a liquid having a specific pressure to the closely adhered article consisting of the plastic molded article and the glass mold after casting polymerization. CONSTITUTION:When a liquid having pressure of 20-70kg/cm<2> is injected to a closely adhered article consisting of a plastic molded article 1 and a glass mold 2 rotating in the circumferential direction thereof from two or more directions, the pressure of the liquid works as a wedge action and, at the same time, the closely adhered article is quenched. By this method, the closely adhered article can be easily released without imparting injury, cracking or damage to the plastic molded article and the glass mold. Further, the time required for release can be also shortened to a large extent. |
