In mixer, add proportioning complete, stir 30 minutes.Sampled by deployed raw material monomer, solidify two pairs of eyeglass test parameters, after parameter testing is qualified, material allocation completes.
Raw material is poured into a mould
Raw material monomer cast link is divided into stirring and cast two parts.
The raw material monomer allocated adds vacuum stirring bucket, stirs 30 minutes, vacuumizes simultaneously.Can sample or form observation bubble situation, stir after terminating and closed vacuum after ten minutes, then add two kilograms of air pressure.
Cast discharge nozzle and heating tape are intertwined, temperature control about 40 degree, extend to solidification machine pan feeding section, can arrange several gate spools according to output from agitator.Cast rifle adopts silicone tube to connect, and the duration of pouring and flow can regulate by handle according to product size, and pouring head can correspondingly adjust according to the difference of product size and specifications and models.
Open discharging ball valve, pressure cast gun handle, raw material is pressed into pipeline by air pressure, discharges air, do not have bubble to uniform discharge by rifle head.Left hand gets glass mold 3, and the right hand tears first mould adhesive tape, pushes down adhesive tape with left index finger, expose mould openings eight millimeter, opening aims at rifle head, right hand pressure handle, raw material injects joystick when reaching volume ninety percent and reduces flow, slowly waters and fills, and decontrols adhesive tape and twines back original position.The mould poured into a mould is put on the conveyer belt of curing.
Notice that cast overfill pollutes mould, cast is discontented bubble, and product all can be caused bad.
Ultraviolet photo-curing
Photocuring needs the conveyer belt type curing of configure dedicated, and this equipment is the novel product of making to measure.The crawler belt of specially treated.After start, the different light energies required for different product, curing regulates speed running speed according to luminous energy, drives the product mold needing solidification, enters IR preheating section, UV solidifies section, cooling section, rear discharging.Mould is after UV solidification section accepts light energy, and monomer becomes solid-state from liquid polymerization fast in mould, reaches preliminary molding effect.
Die sinking
Twine the mould that adhesive tape mode is shaped, out can automatic or manual mode from curing, deliver to die sinking department and carry out die sinking.On die sinking platform, the adhesive tape on mold removal, left hand takes mould, and stand up and aim at the edge of a knife under mold opening device, left hand presses a few lower open die device handle gently, just can 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 uses six grooves altogether, and every groove all wants computer heating control and circulating filtration, and one two four five grooves will have ultrasonic.Automatic rinser lower floor is cleaned, and upper strata is dried.First groove, the second groove cleaning agent, the 3rd groove running water sprays, the 4th groove tap water rinse, and the 5th groove pure water rinsing, the 6th groove pure water cuts water.
After mould frame basket is filled, enough certain frame numbers, send to cleaning machine cleaning, scavenging period and cleaning fluid addition are depending on mold fouling situation.The mould cleaned up is made a gift to someone matched moulds workshop again, twines adhesive tape matched moulds with sealing-tape machine.
Matched moulds
Take out A, B mould from mould, first whether have flaw to optical test mould.If useful cleansing tissue dips in solvent process.Mold work in the face of tuyere blows off, put into aluminium circle, then put into sealing-tape machine, tap start button, sealing-tape machine, according to pre-set programs, completes die assembly.Presbyopic sheet, near-sighted sheet, sun sheet, progressive multi-focal have different photometric requirement, and monomer also has different refractivity, in conjunction with different product setting sealing-tape machine program.
The mould dress combined is blue, sends to pouring hall, from new circulation, forms a Rapid Circulation flow production line endlessly.
Post RDBMS
Frame indigo plant filled by the eyeglass that die sinking obtains, and reaches some, sends into post-curing oven.Post RDBMS temperature sets 120 DEG C, and the time sets 1.5 hours, adopts Cycling hot-blast heating mode.Eyeglass is by photo-thermal dual curable, and physics, chemistry, optical check are all qualified.
