Description
Technical field
The present invention relates to a kind of model solid glass continuous shaping method, have may be such that model solid glass product into
In the heat treatment process of type, the effect of avoiding component from being oxidized.
Background technology
Press, glass is because the characteristic with higher printing opacity, therefore display device (such as mobile phone, wrist-watch electronic product) multiselect
Its shell as window part.The visible handheld electric products surface of monarch is typically provided with glass shell, to protect interiors of products
Display module.Glass shell is largely all the profile of flat board at present, so can form seam in the upper surface of electronic product.
Furthermore because the periphery of electronic product must retain the mechanism section of one fixed width, to hold flat glass, therefore electricity
The top surface of sub- product also can not be just utilized completely.Therefore, three-dimensional or bend glass gradually be employed for electronic product
On glass shell.
Flat glass shell is easier to manufacture, and the manufacture of the glass shell with three-dimensional shape is then more not easy.At present, have
The manufacture for having the glass shell of three-dimensional shape generally has two methods：The first is：The flat glass unit of multi-disc is manufactured, then
The glass shell with three-dimensional shape is formed by the mode for pasting edge.It is for second：Manufacture certain thickness cuboid glass
Glass, and after grinding multiple on the cuboid glass to be formed with multi-sided three-dimensional contouring.However, above-mentioned two method is equal
Take time and effort, speed of production is very slow.Generally, due to glass material is a tabular, if to produce one has moulding
Glass, the preferable practice is flat glass material to be arranged at into a upper mould piece and once between module, then in heating
Module, lower module and glass material, so that glass material softens.When above-mentioned glass material softening, upper mould piece and lower mould
Part can carry out mould assembling action, so that upper mould piece moulds the profile of glass material along a matched moulds direction and lower module jointly, so as to
Produce corresponding moulded glass.Chinese patent announces No. M452174 " former for being used for manufacturing the moulded glass " (day for announcing
Patent announcement data reference in 01 day 05 month in 2013), it includes a parent form mold members, one first male mold members, one second
Male mold members, a supporting post-rod and a depression bar.The first male mold members are arranged at the parent model in a manner of retractable
Have on part, the second male mold members are arranged between the parent form mold members and the first male mold members.The supporting post-rod is worn
Located at the parent form mold members, the supporting post-rod is used for ejection in the second male mold members, so as to supporting the second male mould
Part clamps a moulded glass jointly with the first male mold members.The depression bar is arranged at the side of the first male mold members, should
Depression bar is pressed on the first male mold members under being used for, so that the first male mold members mother relative with the second male mold members
Type mold members are moved to a die-closed position, so as to being molded the moulded glass.
Applicant is previously proposed No. M512584 " model solid glass apparatus for continuous formation " being approved, and it is for model
Three-dimensional glass product designs the brand-new design of apparatus for continuous formation, and it is mainly by body of heater, interior feed track, outer feed track, exchange
System and compression system are formed, and the interior feed track is located at furnace interior, and links the exchange system located at the side of body of heater two, outer conveying
Road links the exchange system of the side of body of heater two outside body of heater, and foregoing interior feed track is provided with slide rail, using what is moved as support plate
Track, the body of heater is closed, and imports protective gas, and is distinguished according to processing procedure and have heating zone, high-temperature molding area, Huan Jiang areas and cold
But area, there is heat-resisting material and the heating component regarding temperature needed for fabrication procedures in heating zone, Ji Huanjiang areas of high-temperature molding area, cools down
Area has cooling device, and compression system is located at high-temperature molding area, and plate glass to be formed is placed in mould surface, and mould is then put
In on support plate, entering preheating of the body of heater through heating zone, the high temperature in high-temperature molding area make Glass Transition and by means of compression system pressurization into
Sent out after type, the cooling in Zai Jinghuanjiang areas and the cooling of cooling zone outside body of heater, then be stripped and form.Only, in Glass Transition now
Temperature more and more higher (especially softening temperature containing lead glass high), it is used heat-resisting in model solid glass apparatus for continuous formation
Material is typically that oxide material is formed, and the oxonium ion in heating in heat-resisting material can discharge, more due to model solid glass
The components such as the mould in glass apparatus for continuous formation, it is that metal or graphite are formed, the oxonium ion discharged, it will increase model
Oxygen content in three-dimensional glass apparatus for continuous formation, the oxygen content after protective gas (generally nitrogen) is imported all are higher than
15PPM, the components such as mould are made to detract its service life because of oxidation, for its missing.Now for this missing, propose more preferably square
Method, make model solid glass product shaping more attain it is perfect.
The content of the invention
In order to solve the above-mentioned technical problem, " model solid glass is continuously shaped providing one kind for the main object of the present invention
Method ", includes a closed body of heater, and two ends are provided with exchange system outside body of heater, and furnace interior is provided with air-tight cavity, in air-tight cavity
Link the end exchange system of body of heater two provided with interior feed track, the air-tight cavity is air hermetic, and imports protective gas, and is distinguished according to processing procedure
There are heating zone, high-temperature molding area and cooling zone, at least one layer of insulation layer is provided with heating zone and high-temperature molding area, and in insulation layer
