Die sinking platform on, the adhesive tape on mold removal, left hand take mould, stand up and the edge of a knife be directed under mold opening device, left hand gently press it is several under
Mold opening device handle, it is possible to open mould, takes out product.A, B mould and product will swing in corresponding frame basket.
Pressure head on mold opening device belongs to wearing detail, and periodic replacement is beneficial to die sinking effect.
Mold clean
Cleaning machine amounts to 16 grooves, per groove will computer heating control and circulating filtration, one two three four five grooves will have ultrasonic.Automatically
Cleaning machine lower floor is cleaned, upper strata drying.First groove, the second groove cleaning agent, the 3rd groove originally Water spray, the 4th groove is with originally
Water is rinsed, and the 5th groove is rinsed with pure water, and the 6th groove pure water cuts water.
After mould frame basket is filled, enough certain frame numbers send to cleaning machine cleaning, and scavenging period and cleaning fluid addition regard mould
Depending on pollution condition.The mould for cleaning up is made a gift to someone matched moulds workshop again, and adhesive tape matched moulds is twined with sealing-tape machine.
Matched moulds
A, B mould are taken out from mould, first to optical test mould either with or without flaw.Processed if dipping in solvent with cleansing tissue.Mould
Working face blows off to tuyere, is put into aluminium circle, places into sealing-tape machine, taps start button, sealing-tape machine according to pre-set programs,
Complete die assembly.Presbyopic piece, near-sighted piece, sun piece, progressive multi-focal have different photometric requirements, and monomer also has different refractions
Rate, will combine different product and set sealing-tape machine program.
The mould dress for combining is blue, sends to pouring hall, from new circulation, constitutes an endlessly Rapid Circulation flowing water
Production line.
Solidify afterwards
The eyeglass that die sinking is obtained fills frame indigo plant, reaches certain amount, sends into post-curing oven.Solidify afterwards temperature sets 120 DEG C, time
Setting 1.5 hours, using Cycling hot-blast heating mode.Eyeglass by photo-thermal dual curable, close by physics, chemistry, optical check
Lattice.
The combination and solidification mode that embodiment technique is heating and curing using ultraviolet, the product produced passes through test,
Meet standard, partial properties are also advantageous over the product that present heat cure mode is produced.
The embodiment photo-thermal combination manufacture of table 1 is contrasted with the condition of production that existing heat cure is manufactured
The ultraviolet curing process that embodiment is used is an energy saving and environment friendly technology.Photocuring product is free of solvent, stingless to human body
Swash property, do not discharge waste gas.Solidification production is efficiently convenient, power saving, less manpower, province's glass mold, province place, the tradition two of CR39
Ten hours heat curing process shorten to the ultraviolet curing process of several minutes, and production line balance speed is fast.Wherein, 1.49 Hes of research and development
1.56 two kinds of photo-curing monomers, it is adaptable to which the sun and optical mirror slip, shaped article are good, by testing and have met standard, have
