Problems solved by technology

Such a sudden temperature change may have adverse effects on the manufactured lens, reducing the accuracy of the product such as shape accuracy.
At the same time, this kind of assembly line design has a fatal flaw, that is, once a certain station fails, the entire equipment will shut down, making it impossible to continue production

Abstract

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.

Description

Technical field [0001] The invention relates to the field of optical glass aspheric lens manufacturing, and in particular provides an integrated station molding method. Background technique [0002] At present, in China's optical glass aspheric lens manufacturing enterprises, the molding equipment used is basically still at the stage of relying on imports, with Toshiba of Japan and TDK of South Korea as the leading market. The process principle of the equipment is to complete the molding production of the lens by the relay of multiple stations in an assembly line, such as the instructions attached figure 1 As shown, a plurality of upper and lower molding dies 2 are arranged in the molding chamber 1 according to the number of processes such as heating, pressing, and cooling, and the molding dies are sequentially transferred to apply various treatments to the molded object to continuously produce optical products, such as Patent Document 1 (Patent Publication No. CN105377775A) disc...
