The sealing device has simple structure and skillful concept, by utilizing the compression performance of the gas, the composite mould is dynamically sealed, the sealing performance is reliable and the mould can be used repeatedly, thereby effectively reducing the manufacturing cost of the mould.
Description
Technical field
The utility model relates to a kind of sealing device, specifically is the sealing device of using composite die with the large-scale composite material structural member manufacturing of vacuum introducing technology moulding.
Background technology
The engine room cover of wind power generating set is the protector of wind power generation gear case and relevant corollary system, in order to reduce cost of electricity-generating, the wind power generating set single-machine capacity constantly increases, correspondingly the engine room cover size also constantly increases, the engine room cover performance of composites is required also to improve constantly, early stage composite cabin cover adopts hand to stick with paste technology mostly, this technological investment cost is low, but properties of product are low, unstable product quality, be subjected to workmen's influence big, environmental pollution is big, labour intensity is big and working condition is abominable, and workers ' health is caused very big injury.Advantages such as vacuum forming technique has that properties of product are good, constant product quality, environmental pollution is little and working condition is good progressively replace hand in recent years and stick with paste technology.But the vacuum introducing technology requires mould to have good sealing, and the sealing property of mould directly has influence on the quality of product, as the porosity and the mechanical property of material, even causes the technology failure.The sealing device that vacuum imports still is more or less freely accomplishing in the mould of single structure, but when product has chamfering structure, must adopt composite die, at this moment the sealing of mould just becomes very difficult, becomes vacuum and imports product quality and technology key of success.Chamfering structure is comparatively common in engine room cover and other large scale structures, adopts this structure to help connection and sealing between the parts, also helps the rigidity and the stability that improve structural member.But bring very big difficulty also for simultaneously the manufacturing and the sealing of mould.Because product size is very big, mould is also very big, and the length of its sealed faying face can reach 10m, even longer, at this moment keeps the parallel very difficulty of composite die faying face, and this will improve manufacture difficulty and cost of manufacture greatly.
The utility model content
The purpose of this utility model just is to provide a kind of dynamic sealing means, to solve the problem of composite die poor sealing performance in the prior art.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of sealing device of composite die is used for the sealing of vacuum introducing technology engine room cover manufacturing with composite die, and this device comprises:
Seal groove is located at the faying face of composite die upper and lower mould, cooperates with dynamic seal;
Described dynamic seal is located in the described seal groove, is used for the sealed composite mould.
Wherein, be provided with gas in the described dynamic seal, described gas makes described dynamic seal produce distortion in described seal groove, seals described composite die by the described dynamic seal after the distortion and the applying of described seal groove inwall.
Wherein, described dynamic seal is provided with inflation inlet, in described dynamic seal, charge into gas by described inflation inlet, make described dynamic seal, seal described composite die by the described dynamic seal after the distortion and the applying of described seal groove inwall in described seal groove internal strain.
Wherein, the sealing device of described composite die also comprises:
Sealant is located at the inner surface of described seal groove, is used for fixing described dynamic seal.
Wherein, described sealant is sealant tape, adhesive.
Advantage of the present utility model and beneficial effect are that the utility model is simple in structure, are skillfully constructed, and utilize the compression performance of gas, the dynamic seal (packing) composite die, and sealing property reliably can repeatedly use, and can effectively reduce the cost of manufacture of mould.

The specific embodiment
Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
Fig. 1 is the overall schematic that is provided with the composite die counterdie of seal groove in the utility model, and Fig. 2 is the enlarged diagram of Fig. 1 chain-dotted line part.As shown in Figure 1 and Figure 2, on the counterdie 10 of engine room cover composite die,, right part flange flange seal groove 11, afterbody flange flange seal groove 12, left part flange flange seal groove 13 are set along the faying face of composite die upper and lower mould.Fig. 3 is the schematic cross-section that seal groove is arranged on the composite die counterdie, also be composite die upper and lower mould in conjunction with after schematic cross-section.As shown in Figure 3, dynamic seal 30 is set in seal groove, dynamic seal 30 has certain retractility, in be filled with gas, can fully contact with the inner surface of seal groove after dynamic seal 30 compression or the expansion.
In the present embodiment, seal groove is only opened on the counterdie of composite die, but seal groove also can open at patrix, or upper and lower mould is all opened (as shown in Figure 4).The cross sectional shape of seal groove can be for square or circular, trapezoidal or other geometries.
Below sealing principle of the present utility model is described:
At first, in the seal groove of composite die counterdie, place dynamic seal, charge into air in the dynamic seal in advance, for dynamic seal is fixed in the seal groove, can use sealant tape or adhesive at contact-making surface, afterwards, utilize bolt device that upper and lower mould is fixed, along with further being screwed into of bolt, thereby the dynamic seal that is placed in the seal groove is subjected to the patrix extruding to produce distortion, finally is deformed into the shape identical with the cross section of seal groove, at this moment, the tube wall of dynamic seal can fully be fitted with the inner surface of seal groove, and then reaches the effect of sealed composite mould.
Perhaps, with the upper and lower mould of composite die with bolting after, by charging into air in the dynamic seal of inflation inlet (not shown) in seal groove, along with being blown into of air, dynamic seal will be expanded laterally, expand into the shape identical with the cross section of seal groove at last, at this moment, the tube wall of dynamic seal can fully be fitted with the inner surface of seal groove, and then reaches the effect of sealed composite mould.
The utility model has utilized the compressibility of gas, and composite die is carried out dynamic seal (packing), and the utility model simple in structure, be skillfully constructed, sealing property reliably can repeatedly be used, and can effectively reduce the cost of manufacture of mould.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
