Mould A is pushed to precompressed station by moving-mold mechanism, (driven mold B enters heat station simultaneously, mould C enters low-temperature heat station) cylinder of precompressed station drives upper heat block to move down contact mould A, and be heated to softening temperature T3 and go forward side by side the precompressed of oozy glass stock;
Mould A is pushed to hot pressing station by moving-mold mechanism, (driven mold B enters precompressed station simultaneously, mould C enters heat station, mould D enters low-temperature heat station,) cylinder of hot pressing station drives upper hot-plate to move down contact mould A, be heated to molding temperature T4 and carry out hot pressing, keeping for some time;
Mould A is pushed to pressurize station by moving-mold mechanism, (driven mold B enters hot pressing station simultaneously, mould C enters precompressed station, mould D enters heat station, mould E enters low-temperature heat station,) cylinder of pressurize station is add certain pressure to mould, and makes mould drop to temperature T5;
Mould A is pushed to annealing station by moving-mold mechanism, (driven mold B enters pressurize station simultaneously, mould C enters hot pressing station, mould D enters precompressed station, mould E enters heat station, mould F enters low-temperature heat station) cylinder of annealing station moves down contact mould A mould is dropped to annealing temperature T6;
Mould A is pushed to cooling station by moving-mold mechanism, (driven mold B enters annealing station simultaneously, mould C enters pressurize station, mould D enters hot pressing station, mould E enters precompressed station, and mould F enters heat station, and mould G enters low-temperature heat station,) cooling station cylinder drives upper cooling plate move down contact mould A and cool mould, temperature dropped to room temperature T7; Mould A has been shifted out depanning from the left plate of die cavity by last moving-mold mechanism.
Whole moving-mold mechanism to 7 moulds be on each station simultaneously shifting formwork time, only need the longest processing stations when reaching requirement, just can carry out shifting formwork, every shifting formwork once can production a slice aspherical glass lens, and such production efficiency is much higher than single station.
Effect of the present invention is: a kind of aspherical glass lens Multi-station precision molding device provided, contrast with existing glass lens hot extrusion briquetting technique, principal feature is: adopt multi-work-station layout, both improve production efficiency, and which in turn improved product over-all properties; Adopt ultraprecise mould, ensure that formed product precision.
