Integrated station mold pressing ing method

Abstract

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.

Description

technical field [0001] The invention relates to the field of manufacturing optical glass aspherical lenses, 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 in the stage of relying on imports, with Japan's Toshiba and South Korea's TDK as the market leaders. The technological principle of the equipment is to complete the molding production of the lens with the relay of multiple stations in an assembly line, as shown in the attached manual figure 1 As shown, according to the number of treatments such as heating, stamping, cooling, etc., a plurality of upper and lower molding dies 2 are arranged in the molding chamber 1, and the molding dies are sequentially transferred to perform various treatments on the molding object, thereby continuously producing optical products, such as The manufacturing device of the...

AI Technical Summary

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
