Abstract
The invention relates to a method for manufacturing a mould sheet of a resin lens. The method of the invention is characterized by comprising the steps as follows: (1) float glass or flat glass is cut into a glass wafer; (2) the glass wafer is placed in a softening furnace to be heated and softened for a certain time within the temperature range of 100 DEG C to 750 DEG C according to the material of the glass wafer; (3) the glass wafer after the softening treatment is placed in a pressing mould and then exposed to pressure of 1 to 6kg according to the material of the glass wafer so as to lead the glass wafer to be pressed into the mould of the resin lens. The method of the invention has the advantage that since the float glass or the flat glass is adopted to produce the mould sheet of the lens, the process of raw material melting in the original technology is avoided, thus having high production efficiency, significant reduction of cost, and reduction of energy consumption and pollution.
Description
Technical field
The present invention relates to the manufacture method of resin lens mould, particularly make the method for resin lens mould with float glass or sheet glass.
Background technology:
Resin lens because of its have lightweight, attractive in appearance, impact resistance strong, be difficult for broken and be convenient to advantage such as batch process, very popular for a long time.Making resin lens needs to make a pair of glass mirror with certain curvature earlier as die blade, then with cope and drag pattern tool sheet sticking and, form a cavity identical between two die blade with resin lens, perfusion resin finally forms resin lens in cavity.
And the traditional method of mfg. moulding die sheet is to adopt cast moulded section method, promptly adopt optical glass material, through electric smelter, the fusing of platinum pot, be poured into compression moulding in the mould of pressing machine, form resin lens die blade blank, then further be processed into satisfactory resin lens die blade through grinding etc.Yet, the resin lens die blade that adopts optical glass material to make, its impurities of materials is many, crackle is many, bubble is many, and hardness is relatively low, and frangible, easily fried, easily split, there are some insoluble problems in the quality of resin lens die blade, work-ing life is not high, and in addition, equipment such as employing electric smelter exist starting material, the electricity charge, artificial contour cost factor, cause the cost of making the resin lens die blade very high, efficient is too low.
Summary of the invention
Purpose of the present invention is exactly at the cost height that exists in the prior art, inefficient shortcoming and a kind of method of utilizing float glass or sheet glass directly to make the resin lens mould that provides.
To achieve these goals, the present invention adopts following technical scheme:
Make the method for resin lens mould with float glass or sheet glass, it is characterized in that may further comprise the steps: (1), with float glass or sheet glass cuts into glass wafer; (2), above-mentioned glass wafer is placed in the softening furnace, according to the material of glass wafer, in 100 ℃ of-750 ℃ of scopes, glass wafer is carried out the thermoplastic of certain hour and handle; (3), the glass wafer after softening the processing puts into compacting tool set, according to the material of glass wafer, gives 1kg-6kg pressure, makes glass wafer be pressed into the resin lens mould.
In the technique scheme, adoptable notch cuttype temperature heat treated is handled in thermoplastic, that is: 100 ℃ of-300 ℃ of preheatings of a warm area, about 12 minutes of time spent, preheating finishes that to enter two warm areas softening in advance with 300 ℃ of-600 ℃ of temperature, about 6 minutes of time spent, it is fully softening with 600 ℃ of-750 ℃ of temperature to enter three-temperature-zone, 4 minutes times spent; Before pressing mold, compacting tool set is carried out preheating.
The invention has the advantages that: owing to adopt float glass or sheet glass to make die blade, the raw material that has omitted in the former technology is founded process, so method production efficiency height of the present invention, and cost significantly reduces, and cuts down the consumption of energy, and reduces and pollutes.
Embodiment:
One: cutting:, cut into glass wafer shape tablet with alloy knife with float glass.
Two: the softening processing:
1, the softening furnace profile is about 4 meters, and is wide about 1 meter.Furnace chamber is a carbon stone silicon flue, and flue is outward cotton insulation of two layers of lagging material silicic acid and insulating brick.
2, softening furnace automatic threading system one is that net belt type send sheet, the one, and the continuous push jack of cylinder, two kinds of modes all can satisfy the press continuous production.
3, the softening furnace heating material can adopt nickel chromium triangle electricity tungsten filament or globars material.A plurality of warm area signals collecting are gone up in temperature control.Full-automatic temperature control system.
4, the glass wafer tablet is 100 ° of-300 ° of preheatings of a warm area in softening furnace, about 12 minutes of time spent; Preheating finishes that to enter two warm areas softening in advance with 300 ° of-600 ° of temperature, about 6 minutes of time spent; It is fully softening with 600 ° of-750 ° of temperature to enter three-temperature-zone, 4 minutes times spent.
Three: moulded section:
Because the difference of tablet diameter, thickness difference, radius-of-curvature difference and mold heated temperature difference.The pressure of cylinder is different, and the calendering asynchronism(-nization) illustrates with following three groups of examples:
Example 1 is as compacting diameter 70*4+0/-0 die blade (* 4 thickness+0/-0 radius-of-curvature)
Mould is heated 200 °, and cylinder is given and pressed 1.0kg, 0.8 second calendering time.
Example 2 is as compacting diameter 75*6+6/-6 die blade.
Mould is heated 300 °, and cylinder is given and pressed 2.5kg, 1.5 seconds calendering time.
Example 3 is as compacting diameter 78*8+12/-12 die blade.
Mould is heated 450 °, and cylinder is given and pressed 3.5kg, 3 seconds calendering time.
The triadic relation adjusts with the tablet difference.
Four: annealing: can satisfy the annealing of this product with existing production technique.
Product performance:
Because adopting raw material is float glass or sheet glass, the glass mold of being produced does not have bubble, no striped, and hardness is strong, highly polished characteristics. and try out through how tame resin lens producer, the number of times that recycles will be higher than existing handicraft product 8-10 time/sheet.
