Description
Technical field
The utility model relates to chemical field, specifically a kind of mould structure for preventing glass reinforced plastic from shrinking layering.
Background technique
Blade is a kind of fibre glass product manufacture, and in production engineering, more universal use vacuum fills fibre glass product manufacture at present
Note technique, this technique mix with curing agent in process of production, by the host agent of polymer resin, heat, react, solidifying；Polymerization
Resin first has liquid to gel under the action of curing agent, finally arrives insoluble insoluble solid-state, resin is in entire reaction process
Release thermal energy, after the reaction was completed temperature gradually fallen after rise by peak value the resin shrinkage to environment temperature, and after solidify deform be exactly because
The contraction generated under the condition of high temperature to state of cooling when solidification；
Blade will take out flange 10cm during laying, and glass-fiber-fabric is compacted on mold by vacuum perfusion process,
Enter glass-fiber-fabric to resin infusion, polymer resin, which solidifies, has certain shrinkage, leads to the several layers of glasses for being pasted in die surface
Unchanged, remaining glass layer of cloth causes root lamination occur, it is therefore necessary to practical since polymer resin solidifies after-contraction
A kind of novel mould structure for preventing glass reinforced plastic from shrinking layering solves problem above.
To solve the above problems, we have invented the toolings that flange is increased in root.The tooling for increasing flange is wanted and die methods
Blue side will flush, while tooling is required to reuse, and guarantees vacuum with type after placing upper mold with mold inner flange
When perfusion, bad vacuum bag film will not be pricked at tooling.
Utility model content
The purpose of this utility model is to provide a kind of mould structures for preventing glass reinforced plastic from shrinking layering, to solve above-mentioned back
The problem of being proposed in scape technology.
To achieve the above object, the utility model provides the following technical solutions:
A kind of mould structure for preventing glass reinforced plastic from shrinking layering, comprising: mold, root increase flange tooling and glass-fiber-fabric,
The root is increased flange tooling and is fixed on mold, fixes after root increases flange tooling, the root increase flange with
Mold inner flange side flushes, and after structure adhesive curing, takes out root and increases flange tooling, flange work is increased in the mold and root
Impulse- free robustness is filled, avoids pricking bad to glass-fiber-fabric；The effect that flange tooling is increased in root is to increase the height of flange, the effect of structure glue
It is that flange tooling is increased in fixed root, guarantees that tooling will not shift because glass-fiber-fabric is laid with, it is therefore prevented that glass reinforced plastic solidification
Root lamination caused by after-contraction reduces maintenance time and the material consumption of glass reinforced plastic, has saved product cost.
There is structure glue to be fixed in the upper of mold as a further solution of the present invention: flange tooling is increased in root
Side, smears deployed structure glue on mold flange.
The inside and root mold inner flange side for increasing flange tooling as a further solution of the present invention,
It flushes.
Two layers of glass-fiber-fabric of hand paste on the outside of flange tooling is increased in the root as a further solution of the present invention,
Bag is played convenient for flange below to vacuumize, and prevents from falling off when vane mold matching.
Flange tooling is increased by using root as a further solution of the present invention, glass reinforced plastic can be increased
The internal stress generated after solidification, the height for being layered root increase, avoid and occur defect on fibre glass product manufacture.
The glass-fiber-fabric is mainly by glass fibre and short-term needle punched non-woven fabrics as a further solution of the present invention,
It is combined, is a kind of inorganic non-metallic material haveing excellent performance.
Compared with prior art, the utility model has the beneficial effects that wind power blade prevents glass reinforced plastic after priming by vacuum
The technology of layering is shunk, when cured, glass reinforced plastic shrinks problem, takes the technology for increasing flange, improves root portion
The process control of layer；Increase flange root by polyester resin and increase flange tooling, after can solidifying to avoid glass reinforced plastic in generation
Stress leads to root lamination；After increasing flange tooling using root, it can occur to avoid the phenomenon that root portion layer defects, subtract
The maintenance work for having lacked glass reinforced plastic, improves work efficiency, while also improving the quality of product；The present invention is in technical problem solution
On certainly, good benefit has all been embodied in terms of cost control.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of mould structure for preventing glass reinforced plastic from shrinking layering.
In figure: 1- mold, 2- increase root flange tooling, 3- glass-fiber-fabric.
Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
Embodiment 1
Referring to Fig. 1, a kind of mould structure for preventing glass reinforced plastic from shrinking layering, comprising: mold 1, root increase flange work
2 and glass-fiber-fabric 3 are filled, the top that flange tooling 2 has structure glue to be fixed in mold 1 is increased in root, smears on 1 flange of mold
Deployed structure glue, and flange tooling 2 is increased into root and is fixed on mold 1, inside and the root of flange tooling 2 are increased in root
Mold 1 inner flange side in portion's flushes, and fixes after root increases flange tooling 2, then carry out the next step, with 1 inner flange of mold
While flushing, after structure adhesive curing, to take out root and increase flange tooling 2, flange tooling impulse- free robustness is increased in the mold and root,
It avoids pricking bad to glass-fiber-fabric, root increased into flange tooling 2 with sander is higher by the glass reinforced plastic of 1 flange of mold and cut away；Root
The effect for increasing flange tooling 2 is to increase the height of flange, and the effect of structure glue is that flange tooling 2 is increased in fixed root, is guaranteed
Tooling will not shift because glass-fiber-fabric is laid with；Flange tooling 2 is increased by using root, glass reinforced plastic solidification can be increased
The internal stress generated afterwards, the height for being layered root increase, avoid and occur defect on fibre glass product manufacture, it is therefore prevented that glass reinforced plastic is solid
Change root lamination caused by after-contraction, reduces maintenance time and the material consumption of glass reinforced plastic, saved product cost, institute
It states root and increases 2 outside hand of flange tooling, two layers of glass-fiber-fabric 3 of paste, the glass-fiber-fabric 3 mainly pierces nothing by glass fibre and short-term needle
What woven fabric was combined.
Embodiment 2
Further, flange tooling 2 is increased using glass-fiber-fabric hand paste moulds of industrial equipment in the root, is highly 2-3cm, width
For 4-6cm, length 170-180cm, the root of production increases flange tooling 2 and is fallen the sanding burr on surface with sander, work
It is coarse to fill surface polishing, clears up dust, scratches tooling surface with painter's putty, guarantees that tooling surface is smooth.
Embodiment 3
Preferably, the glass-fiber-fabric 3 is mainly combined by fiberglass fibers and polyester fiber, is that a kind of performance is excellent
Different inorganic non-metallic material is played bag convenient for flange below and is vacuumized, and prevents from falling off when vane mold matching.
The preferred embodiment of the patent is described in detail above, but this patent is not limited to above-mentioned embodiment party
Formula within the knowledge of one of ordinary skill in the art can also be under the premise of not departing from this patent objective
It makes a variety of changes.
