Abstract
The invention relates to a glass reinforced plastics air pressure forming manufacturing method. It can effectively solve the problem that both sides of the glass reinforced plastics product is gabrous, especially the big internal mold cavity, and small collar extension. The technical proposal are that resin and fiber are coated between the hard outer mold and the soft inner mold; after sealing the mold gland is fixed and aerated to increase pressure; or after air proof hold down strip is sealed, the inner and outer mold are set in the pressure container to aerate, increase pressure, and solidify. The invention can solve the pressing problem which can not be solved by the existing pressure forming technology, which means no matter how complicate the shape of the product is, it still can make the both sides of the product be gabrous. Its advantages are that the manufacturing technique is unique; the effect is good; the quality of the product is good; the appearance is beautiful; the market is wide; and the economic benefit is notable.
Description
One, technical field
The present invention relates to a kind of air-pressure forming method, particularly a kind of fiberglass air-pressure forming manufacture method of producing fibre glass product manufacture.
Two, background technology
At present, generally the fiberglass forming method of Cai Yonging has hand pasting forming, compression molding, cast molding and method (technology) such as Wrapping formed, above-mentioned forming method is for complex-shaped strange, the little product of big, the outer bore in internal mold abdominal cavity particularly, can't make product obtain the bright and clean smooth outward appearance in two sides (interior outside), influenced the quality of product greatly, use value and sale have influenced the production and the development of fiberglass.
Three, summary of the invention
At above-mentioned situation, the present invention's purpose just provides a kind of new fiberglass air-pressure forming manufacture method (production technology), it is bright and clean effectively to solve the fibre glass product manufacture two sides, particularly the internal mold abdominal cavity is big, the problem that the fibre glass product manufacture that outer bore is little is pleased both parties, the technical scheme of its solution is behind even coating resin of hard external mold inwall and fiber, again the internal mold that utilizes soft material to make is put into die cavity, use mould gland compaction mold bore then, utilize the air-filled pore inflation pressurization on the mould gland, then realize that the product two sides is bright and clean or at even coating resin of external mold inwall and glass fibre, the internal mold that soft material is made is put into die cavity, utilize in the seal trim strip sealing in mould aperture, outer mold, again in the good seal, outer mold is put into pressure vessel sealing extrusion forming, or interior, casting thermosetting resin or thermoplastic resin solidify or the cooling aftershaping after the outer mold heated sealed, bright and clean to reach the product two sides, the present invention can solve the existing indeterminable compacting problem of die press technology for forming, the i.e. how complicated product of tube shape not, all can make the product two sides bright and clean, production technology (method) uniqueness, effective, the product quality height, attractive in appearance, extensive market has remarkable economic efficiency.

Five, the specific embodiment
According to aforementioned, the present invention is coating resin and a fiber between hard external mold and soft internal mold, sealing back fixed mould gland, inflation is pressurizeed or the inside and outside mould after sealing with seal trim strip is put into pressure vessel, inflation cure under pressure or after hard external mold and soft internal mold sealing pressurization, casting thermosetting resin or thermoplastic resin are heating and curing or cool off aftershaping and get final product.
Describe the specific embodiment of the present invention in detail below in conjunction with drawings and Examples.
It is big that Fig. 1, Fig. 2 have provided the internal mold abdominal cavity, vase moulding process and die drawing that outer bore is little.By Fig. 1, shown in Figure 2, the present invention is, fixture bolt 9 is compressed mould fixture 8, hard external mold 1 is closed up to be fixed together, after hard external mold 1 inwall that fixes is coated with rich resin and fiber 3, soft internal mold 2 is inserted wherein, tension mould seal trim strip 7, utilize mould gland bolt 6 compaction mold glands 4, in soft internal mold 2 cavitys, inflate pressurization through the air-filled pore on the mould gland 45 again, dry solidification moulding or in hard external mold and soft internal mold sealing pressurization, cast then thermosetting resin or thermoplastic resin are heating and curing or cool off aftershaping and get final product.
Said hard external mold 1 available metal material is made, also useable glass steel or various thermoplastic resin or thermosetting resin or armored concrete is any makes; Soft internal mold 2 can with various elastomeric materials or soft resilient thermoplastic material or the flexible thermosetting resin is any be made; Form the resin and the fiber 3 of product, the fiber that fiber can adopt glass fibre, carbon fiber, cotton fiber or various resin to make is used in any or two or more collocation in the available heat thermosetting resin; Also can solidify the cooling aftershaping at inside and outside mould sealing pressurization back casting thermosetting resin or thermoplastic resin; Mould gland 4, air-filled pore 5, mould gland set bolt 6, external mold is to mould fixture 8 and be fixed the bolt 9 of part, and all the available metal material is made, also available firm plastics manufacturing; Mould seal trim strip 7 can adopt the fiber of metal material or plastics or leather to make, and during use, utilizes the way of tension to compress soft internal mold outward flange.
As without the mould gland, can put into pressure vessel to the inside and outside mould of good seal, the inflation pressurization also can make the product two sides bright and clean in pressure vessel.
The material of suitable for making pressure vessel is: metal, concrete and armored concrete, timber, thermosetting resin and thermoplastic resin, also available masonry are built to build to whitewash and are formed, and also available various fibers and the rubber baking that is suitable for rubber adhesion of having ready conditions forms.
The present invention also can be used for the production of other similar products, as plastic products and ceramic batch or cement moulding etc.The present invention has wide purposes, applies market prospects light.
