The invention provides an integrated mold pressing method. The method comprises the steps: (1) putting a to-be-processed workpiece on a lower mold of a
station substrate plate; (2) controlling a
stamping rod to move downwards so as to abut a sealing cover sleeve against the
station substrate plate and form a mold pressing chamber; (3) removing air in the mold pressing chamber, and filling nitrogeninto the mold pressing chamber so as to make the mold pressing chamber under the protection of
nitrogen; (4) heating the upper mold and the lower mold to a mold pressing temperature; (5) controllingthe
stamping rod to continue to move downwards so as to make the upper mold and the lower mold complete mold clamping, and performing maintaining for a certain period of time so as to complete
stamping and pressure maintaining; (6) removing the high temperature
nitrogen in the mold pressing chamber, and filling low temperature
nitrogen into the mold pressing chamber so as to reduce the temperaturein the mold pressing chamber; (7) controlling the stamping rod to move upwards so as to separate the upper mold and the lower mold; and (8) taking out the formed workpiece. Through the integrated mold pressing method, heating, stamping, cooling and other processes of
optical glass lenses can be achieved at one
station, the molds are saved greatly, the use cost is reduced, and meanwhile the stability of the workpiece is ensured.
