The invention provides an integrated molding method. The method comprises the following steps: S1), placing a to-be-processed workpiece on a lower mold on a
station substrate; S2), controlling a
punching rod to move downwards to enable a sealing cover sleeve to abut against the
station substrate to form a molding chamber; S3), removing air in the molding chamber and feeding
nitrogen in the molding chamber to enable the molding chamber to be under protection of
nitrogen; S4), heating an upper mold and the lower mold to the molding temperature; S5), controlling the
punching rod to continue to move downwards to enable the upper mold and the lower mold to be closed and keep closed for a certain time to finish
punching and pressure maintaining; S6), removing high-temperature
nitrogen in the molding chamber and feeding low-temperature nitrogen to reduce the temperature in the molding chamber; S7), controlling the punching rod to move up to separate the upper mold from the lower mold; S8), taking out the formed workpiece. According to the integrated molding method, processes such as heating, punching and cooling of an
optical glass lens are achieved in one
station, the mold is greatly saved, the use cost is reduced, and stability of the workpiece is ensured.
