Abstract
The invention discloses a method for continuously molding special-shaped fiber fittings. In the invention, a mould main body is made of expanded polystyrene materials. The method comprises the following steps of: firstly, coating a high-temperature resistant synthesized emulsion layer on the entire outer part of the mould main body and preserving at least one charging port; secondly, tightly winding a fiber band on the surface of the emulsion layer and placing the whole body into a plain die of a bolt locked die to heat the whole body, heating and smelting the fiber band in a curing process to obtain a fiber material with a degree of freedom and charging a high-pressure gas from the charging port on the emulsion layer so that the fiber material is pushed by the expanded emulsion layer to be adhered to a cavity surface of the die to perform curing; and thirdly, performing a cooling molding process to cool the die and carrying out a die cleaning process to obtain the finished products of the fiber fittings. The pipe wall thicknesses of the finished products of the fiber fittings can be effectively controlled in the binding process, so the fiber fittings meeting variable stable strength requirements (including different pipe wall thicknesses) can be produced simply and quickly.
Description
Technical field
The present invention relates to the fiber fittings that simple and easy and stable the producing of a kind of energy meets various (different pipe thickness) requirement of strength, and make the method for continuously molding special-shaped fiber fittings that flow process more accords with economic benefit.
Background technology
Current, the forming technique of known fiber fittings is a kind of worker's method by similar blow molding.Fiber preimpregnation material package is tied up outside the nylon airbag, placed the inner chamber of mould, fill gases at high pressure again and enter in the nylon airbag, be aided with mold heated and make the slaking of fiber material, make pipe fitting product with the consistent moulding of dies cavity.But the tube manufacture of this traditional unfavorable moulding complexity of moulding worker method, because the nylon airbag is too soft, when making the pre-type body of pipe fitting (having pre-type body depression problem), can't obtain the model consistent with product-forming, and cause folding line, the wrinkle defective of fiber fittings finished product, even the inefficacy of mechanical property.Several No. 200620061857.5 of the existing People's Republic of China (PRC) patent No. " the novel patent case of a kind of latex airbag model J; then be identical with the moulding of fiber fittings goods; the mandrel that size is dwindled is nested with the latex airbag consistent with the mandrel moulding outward; in the enforcement; be that fiber preimpregnation material package is tied up outside the latex airbag that is nested with outside mandrel places dies cavity to fill with gases at high pressure again and is aided with the curing temperature of fiber prepreg; Product is made the back and with mechanical system or adopt the dissolution with solvents of unlikely corrosion fiber and base material to remove the mandrel that EPS makes and remove the latex airbag, is obtained the fiber fittings finished product; Though this latex airbag model can improve the non-persistent shortcoming of traditional worker's method model, yet mandrel is nested with the latex airbag of moulding unanimity in the mode of wearing, and this is for the formation of tubes of many bendings or many turnovers, have the scarce fraud that the latex airbag is difficult for being set on the mandrel appearance, very consume human cost; And outside the latex airbag, be to tie up the mode bag with the patch bag to tie up the fiber prepreg, because it is not the successional bed of material (having tomography) that soaks that described fiber preimpregnation material package is tied up outside the latex airbag, virtually, pipe fitting by fiber prepreg slaking moulding, its tube wall strength is extremely unstable, even thicken the bed of material, also may not make the effectively control of stability of tube wall strength; In addition, known or existing formation of tubes mould all is to utilize the oil hydraulic cylinder Mould locking machine to carry out the action of mould ON/OFF mould, and heating makes its slaking to the fiber prepreg to be aided with the interior ripe source of accessory; Because the fiber prepreg reaches the temperature of slaking will be for some time; add the time of cooling and shaping; the oil hydraulic cylinder Mould locking machine has very long stand-by time loss in the process of continuous operation, with and belong to the production equipment of cost with high investment, directly influence the economic benefit that fiber fittings is produced.
Summary of the invention
Main purpose of the present invention is that a kind of method for continuously molding special-shaped fiber fittings is being provided, and solves the variety of issue that exists in the prior art.
