Abstract
The invention relates to a forming method of an organic glass part with a narrow-strip-shaped multi-curved-surface high-curvature appearance. The method is mainly characterized in that firstly, organic glass is preheated to the forming temperature and is then placed on a female die forming mold, a press plate is pressed, the vacuum pumping is carried out, meanwhile, and a local press mold is pressed on the tail narrow-strip-shaped position until the appearance realizes the complete mold pasting. The forming method has the advantages that the vacuum pressure forming principle is utilized, meanwhile, the local press mold is also utilized, and the problem that the organic glass molding cannot be sufficiently formed because the area of the tail narrow-strip-shaped curved surface is small and the formed vacuum pressure is low is solved.
Description
Technical field
The invention belongs to the aerial organic glass moulding technique, particularly a kind of forming method with narrow many curved surfaces of strip deep camber profile lucite product.
Background technology
The aerial organic glass forming method has formpiston contactmolding, former vacuum contactmolding, matched-mold forming method, the pneumatic contactmolding of former, framed vacuum free forming prooess, framed blowing free forming prooess and the retraction method of forming usually.A kind ofly be with narrow many curved surfaces of strip deep camber profile aerial organic glass product, because product complex contour, particularly afterbody are narrow strip curved-surface structure, shaping area is little, and formed vacuum pressure is low, not enough so that here lucite paste mould.During the product moulding, use former vacuum contactmolding separately, the narrow strip curved surface of product afterbody can't paste mould; Use the matched-mold forming method separately,, in forming process, force the formed gauffer that stretches to eliminate, and product has certain optics requirement because the product profile is too complicated.Adopt existing aerial organic glass forming method can't obtain the product of coincidence pattern requirement.
Summary of the invention
(1) the object of the invention
Be the problem of solution, the present invention proposes a kind of forming method, i.e. vacuum-local pressing mold combination forming method with narrow many curved surfaces of strip deep camber profile aerial organic glass product with the moulding of narrow many curved surfaces of strip deep camber profile lucite product.
(2) technical scheme of the present invention
The technical scheme that the present invention takes is: a kind ofly be with narrow many curved surfaces of strip deep camber profile lucite product forming method, it is characterized in that may further comprise the steps:
The first step is ready to relevant former device, comprises baking oven, female mould forming mould, pressing plate, local pressing mold and vacuum equipment;
Second step cut lucite by size, threw off the lucite protection sheet, dried after lucite is cleaned;
In the 3rd step, place the baking oven of heating to be incubated in lucite to forming temperature;
In the 4th step, 1min places the baking oven preheating with pressing plate and local pressing mold before lucite is come out of the stove;
In the 5th step, the lucite taking-up that heating is reached temperature retention time places on the female mould forming mould, gently presses it with the good pressing plate of preheating again, and making it when vacuumizing, not upspring gets final product;
The 6th step, connect vacuum, simultaneously that preheating is good local pressing mold is pressed into narrow strip position, makes it to paste mould;
The 7th step, treat to stop to vacuumize behind the lucite product cooling and shaping, shed local pressing mold and pressing plate, take out product, and rule and cut by the groove on the mould, obtain product.
Wherein, adopting thickness with narrow many curved surfaces of strip deep camber profile aerial organic glass product is the YB-2 aerial organic glass of 1mm; Lucite is shelved in the baking oven and heats, and temperature remains on 150 ± 5 ℃; It is 10min that lucite is shelved on the interior temperature retention time of baking oven.
(3) beneficial effect of the present invention
Method of the present invention has been utilized the vacuum pressure forming principle, uses local pressing mold simultaneously, has solved the narrow strip curved surface of product afterbody because shaping area little, formed vacuum pressure is low, deficiency is so that lucite pastes the problem of mould.
Description of drawings
Fig. 1 is a kind of narrow many curved surfaces of strip deep camber profile aerial organic glass product of being with.
The specific embodiment
One embodiment of the present invention are following: certain aircraft wing wing tip is many curved surfaces of the narrow strip of a kind of afterbody band deep camber profile aerial organic glass product, and adopting thickness is the YB-2 aerial organic glass of 1mm.Forming step is: cut lucite by size, throw off the lucite protection sheet, dry after lucite is cleaned, place the baking oven (lucite is shelved on the platform of band flannelette in the baking oven) of heating to 150 ± 5 ℃, insulation 10min.1min places the baking oven preheating with pressing plate and local pressing mold before lucite is come out of the stove, by the time after the temperature retention time, take out lucite and place on the female mould forming mould, gently presses it with the pressing plate that preheating is good, and making it when vacuumizing, not upspring gets final product.Connect vacuum, simultaneously that preheating is good local pressing mold is pressed into the narrow strip of afterbody position, makes it to paste mould.Treat to stop to vacuumize behind the lucite cooling and shaping, shed local pressing mold and pressing plate, take out product.Observe molding effect, the person of meeting the requirements rules by the groove on the mould and cuts, and obtains product.
This invention also can be used for the moulding of the lucite product of similar complex contour structures.
