Description
Technical field
The present invention relates to the instillation process in the industrial production, specifically relate to a kind of one-body molded instillation process of semiclosed glass fiber reinforced plastics product with the invagination flange.It can be widely used in the semiclosed large-scale composite material production with the invagination flange, for example wind-driven generator case product and blade of wind-driven generator or the like.
Background technology
Priming by vacuum is a kind of technology of utilizing vacuum pressure to make moulding, its notion is directly to be laid in fibre reinforced materials and foamed material etc. on the mould, form the goods skeleton, coat with the vacuum seal film then, sealed mold, then be pumped to negative pressure state with vavuum pump, last resin pours into the entire die system by the glue inlet tube on the diaphragm seal, soaks into each gap of goods skeleton shop layer.Whole filling process needs mould to have good sealing, to guarantee the condition of high vacuum degree in the mould.Vacuum perfusion process and hand are stuck with paste technology and are compared, and its advantage mainly is: 1. health; Safety; 2. consumables cost is low; Flow velocity is fast; Work period is short; Die sinking technology cost is low; 3. fiber reinforcement cloth content is significantly increased; Intensity is higher, and size is more stable; Air bubble content seldom; Reduce man's activity, the stability of improving the quality of products.Thereby vacuum perfusion process is adopted by a lot of manufacturing enterprises.
Yet, the goods that present vacuum perfusion process is fit to can only be Open architecture, that is to say, the goods made from priming by vacuum (are primarily aimed at the galss fiber reinforced resin base composite-material product, be glass fiber reinforced plastics product) must not have the face (being the invagination flange arrangement) of inside turnover, if during, will cause the moulded products can't the demoulding with the goods of vacuum perfusion process one-body molded band invagination flange.Therefore, in common industrial production, the method for generally taking main body and flange to pour into respectively to the goods of band invagination flange, after treating main body and flange form, adopt hand to stick with paste technology the two and bond together, the goods total quality that the method is produced is poor, intensity is low, and is firm inadequately; In addition, the manufacturing process trouble, the work period is long, and labor strength is big.In order to improve time method, shorten the work period, some manufacturing enterprise adopts the goods of the detachable one-body molded band invagination of mould flange, as depicted in figs. 1 and 2: make and the suitable mould of goods that will pour into, this mould comprises main part 1 and flange section 6, main part 1 is the branch body structure with flange section 6, when perfusion, adopt Screw arbor with nut at both-ends 8 that flange section 6 is fixed on the main part 1, form the mould of band invagination flange, in mould, lay reinforcing fiber materials, form goods skeleton 2, lay the water conservancy diversion net on skeleton 2 surfaces, glue inlet tube road 7 and exhaust pipe 3, lay vacuum seal film 4 at last, the limit mouth of sealing film 4 is bonded on the land area of flange mould 6 with sealant tape 5, and then forms the sealing to mould, has bleeding point and perfusing hole on the diaphragm seal 4.Though it can carry out one-body molded to the goods of band invagination flange, simplify manufacturing process, reduce labor strength, but also there is following main deficiency in it: 1. diaphragm seal fails the mating surface gap of die main body part and flange section is sealed, and makes the mating surface gap of die main body part and flange section form main gas leakage point, the sealing of mould is poor, the vacuum that forms in the mould is low, and then influences quality of item, and scrappage is high, production efficiency is low, and production cost is big; 2. the Screw arbor with nut at both-ends hole that is provided with on die main body part and the flange section has formed less important gas leakage point, further reduces the sealing of mould, influences quality of item and ordinary production.
Summary of the invention
The objective of the invention is to: at above-mentioned the deficiencies in the prior art, a kind of vacuum perfusion process of efficient quick is provided, specifically be the one-body molded instillation process of semiclosed glass fiber reinforced plastics product of band invagination flange, the goods that make with it have reduced production cost when ensuring the quality of products.
The technical solution used in the present invention is:
