发明名称 GLASS MOLDING METHOD AND GLASS MOLDING DEVICE USED IN THE METHOD
摘要 A glass molding method for molding a glass preform to a glass product via an assembly mold includes the following steps. The glass preform is preheated to a glass molding temperature. The assembly mold is heated to a predetermined mold temperature lower than the glass molding temperature and maintained at the mold temperature. The preheated glass preform is transferred to the assembly mold. The assembly mold is closed together for molding the glass preform to the glass product. The glass product and the assembly mold are gradually cooled to an open temperature. Then the assembly mold is opened to take the glass product out of the assembly mold.

主权项 1. A glass molding method comprising: providing a glass preform and an assembly mold, the assembly mold comprising at least two sub-molds; heating the glass preform to a glass molding temperature at which the glass preform is moldable; heating each of the sub-molds to predetermined mold temperatures and maintaining the mold temperatures; transferring the glass preform heated to the glass molding temperature to a molding surface of one of the sub-molds heated to the mold temperature; closing the sub-molds together to form the glass preform into a glass product with a predetermined shape; gradually cooling the glass product and the closed assembly mold to a predetermined open temperature; and separating the sub-molds to take the glass product out of the assembly mold.
