Abstract
The utility model relates to a fan blade mould which comprises a male mold and a female mold, wherein the female mold comprises a sealing layer, an internal structure layer, a heating layer and an external structure layer which are sequentially arranged on the male mold; the sealing layer comprises a first sealing layer and a second sealing layer which are respectively and sequentially provided with an external gel coat, an internal gel coat and a transitional layer; the transitional layer comprises a chopped carpet veneer, a twill weaving cloth layer and a double-axial cloth layer which are sequentially paved; and the external gel coat of the second sealing layer is arranged at the upper part of the transitional layer of the first sealing layer. In the fan blade mould, by arranging the two sealing layers on the female mould of the mould, the quality of the mould is increased, the mould is ensured to have higher using performance in the production process, the quality of blades is ensured, the maintenance work of the mould is reduced, the service life of the mould is prolonged, the consumption cost is reduced, and the using requirements of production on the mould is further satisfied.
Description
Technical field
The utility model relates to a kind of mould, particularly a kind of fan blade mould.
Background technology
Along with the development of wind-power market, the production of fan blade higher dimensional accuracy and quality requirement has been proposed, the particularly development of offshore wind turbine blade.And the quality of fan blade depends on the used mould of production blade to a great extent, this has just proposed higher quality requirement to the former mould of producing blade, promptly require surperficial aerodynamic configuration size accurately, surface smoothness require high, do not have disadvantages such as hiding bubble and pin hole, guarantee good air-tightness.
The former list sealant mould that uses in the prior art has contraction in various degree when being heated, thereby influences the surface size of mould; Sticking to mould during mould semi-finished product molding in use, the polishing when type is repaiied all can damage the gel coating resin of mould; Uneven knockout press causes mould crackle to occur, and the small size extruding comes off; And the gel coating resin damage excessively can exert an influence to transition zone, thereby influences the air-tightness of mould.Mould gas leakage can cause the mass defect of producing blade, brings difficulty to production, influences production efficiency.The frequent infringement of sealant can cause mould to re-use, and loses big inestimable.
Summary of the invention
Technical problem to be solved in the utility model is at the deficiencies in the prior art, and a kind of fan blade mould of rational in infrastructure, long service life is provided.
Technical problem to be solved in the utility model is to realize by following technical scheme.The utility model is a kind of fan blade mould, comprise formpiston and former, described former comprises sealant, inner structure layer, zone of heating and the external structure layer that is successively set on the formpiston, be characterized in: described sealant comprises the 1st sealant and the 2nd sealant, the 1st sealant and the 2nd sealant are provided with outer gel coating resin, interior gel coating resin and transition zone respectively successively, described transition zone comprises that the weak point of laying is cut carpet veneer, twill weave layer of cloth and twin shaft layer of cloth successively, and the outer gel coating resin of described the 2nd sealant is located at the top of the transition zone of the 1st sealant.
Outer gel coating resin described in the utility model can be the mixture of F300 gel coat and the curing agent composition that matches, (the Hexion Specialty Chemicals on sale of F300 gel coat and curing agent Hexion Specialty Chemicals company, Inc), described curing agent can be the curing agent that mates with the F300 gel coat in the prior art.Outer gel coating resin described in the utility model can be the mixture of F900 gel coat and the curing agent composition that matches, (the Hexion Specialty Chemicals on sale of F900 gel coat and curing agent Hexion Specialty Chemicals company, Inc), described curing agent can be the curing agent that mates with the F900 gel coat in the prior art.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described fan blade mould is characterized in: described weak point is cut carpet veneer, twill weave layer of cloth and twin shaft layer of cloth and is provided with epoxy resin layer each other.
Compared with prior art, of the present utility modelly improved the quality of mould, guaranteed the aerodynamic configuration size of blade by on the former of mould, being provided with two sealants, improve the fineness of die surface, ensured the air-tightness of mould and other serviceabilities of mould simultaneously.It has guaranteed that mould has higher serviceability in process of production, has guaranteed the quality of blade, has reduced the maintenance and the maintenance work of mould, prolongs the useful life of mould, reduces consuming cost, has satisfied the instructions for use of producing mould more.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
Following with reference to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the present invention further, and do not constitute restriction to its right.
Embodiment 1.With reference to Fig. 1.A kind of fan blade mould, comprise formpiston 1 and former, described former comprises sealant, inner structure layer 5, zone of heating 6 and the external structure layer 7 that is successively set on the formpiston, described sealant comprises the 1st sealant and the 2nd sealant, the 1st sealant and the 2nd sealant are provided with outer gel coating resin 2, interior gel coating resin 3 and transition zone 4 respectively successively, described transition zone 4 comprises that the weak point of laying is cut carpet veneer, twill weave layer of cloth and twin shaft layer of cloth successively, and the outer gel coating resin 2 of described the 2nd sealant is located at the top of the transition zone 4 of the 1st sealant.
During enforcement, on the formpiston of handling well 1, brush the outer gel coating resin 2 of the 1st sealant earlier, outer gel coating resin 2 is F300 gel coat and the curing agent that matches, and gel coating resin 3 in treating to be coated with again after outer gel coating resin 2 initial sets, interior gel coating resin 3 are F900 gel coat and the curing agent that matches.Treat in gel coating resin 3 initial sets promptly with hand touch do not account for hand after, deployed epoxy resin is brushed on the interior gel coating resin 3 of mould, re-lay transition zone 4, transition zone 4 is cut carpet veneer, twill weave layer of cloth and twin shaft layer of cloth by weak point and is pasted together by resin, and every layer bubble is got rid of in the tool using compacting.After treating that the 1st sealant solidifies, the making of beginning the 2nd sealant on the transition zone 4 of the 1st sealant, operating procedure is the same with the 1st sealant, makes outer gel coating resin 2, interior gel coating resin 3 and transition zone 4 successively.Treat that carrying out technologies such as layer shop, priming by vacuum again after second layer sealant solidifies makes inner structure layer 5, treats to make zone of heating 6 and external structure layer 7 successively after inner structure is solidified.
Embodiment 2.In the embodiment 1 described fan blade mould, described weak point is cut carpet veneer, twill weave layer of cloth and twin shaft layer of cloth and is provided with epoxy resin layer each other.By the matrix of epoxy resin as the connection reinforcing material.
The utility model has improved the quality of mould by making the double density seal, has improved the aerodynamic configuration size of blade, improves the fineness of die surface, has ensured the air-tightness of mould and other serviceabilities of mould simultaneously.In the use of mould,, when not influencing air-tightness, do simple reparation and get final product when the outer gel coating resin 2 and interior gel coating resin 3 generation micro-crack or a spot of destructions of the 1st sealant; When the 1st sealant sustained damage, the 2nd sealant can continue to play a role, and can not influence production efficiency, has solved mould trouble and worry in use, has prolonged the useful life of mould, provided double shield to the serviceability of mould.
