Abstract
The utility model belongs to combined material shaping class technique, in particular to combined material paddle forming die, when solving current mould solidification, thereby unnecessary glue can't the discharge mould influences the problem of paddle shaping quality. Combined material paddle forming die is including being formed with the paddle die cavity between the last mould that matches and lower mould and they, along the gummosis groove that the exhibition was provided with to the direction and the outside communicates of paddle die cavity between the die joint of the die joint of last mould and lower mould, and unnecessary glue along gummosis groove outflow when the paddle solidifies to guarantee the paddle quality, improved the qualification rate of product.
Description
Technical field
The utility model belongs to composite material forming class technology, particularly a kind of composite material blade mould.
Background technology
Composite material blade is the requisite part product of helicopter rotor system, blade is the parts of helicopter most critical, it is the core of helicopter rotor system, the quality of rotor is directly connected to performance and the safety of helicopter, and mould manufactures the important frock of producing composite material blade, the frame mode of mould is the key determining that whether composite material blade is qualified.
During current composite material blade of helicopter is at home shaping, mould die joint spew groove structure is an often uncared-for problem, and existing mould is that overall die joint designs without spew groove, and blade die cavity both sides are all contact surface.In the curing process, unnecessary glue cannot discharge mould, and upper and lower mould cannot be fitted smooth, cause matched moulds excesssive gap and uneven, greatly affect the Forming Quality of blade, thickness is overproof overweight with blade surface gum deposit weight after shaping to cause blade, thus reduces the qualification rate of product.
Utility model content
The technical problems to be solved in the utility model: provide a kind of composite material blade mould, during to solve existing mold solidification, unnecessary glue cannot be discharged mould thus be affected the problem of paddle molding quality.
The technical solution of the utility model:
A kind of composite material blade mould, comprise the upper die and lower die of coupling, blade die cavity is formed between patrix and counterdie, face bonded to each other between described upper die and lower die is die joint, between the die joint and the die joint of counterdie of described patrix, be provided with the spew groove with ft connection along the exhibition of described blade die cavity to direction.
Alternatively, described spew groove is positioned on the die joint of described counterdie.
Alternatively, described spew groove comprises two, is symmetricly set on longitudinal both sides of described blade die cavity.
Alternatively, the cross section of described spew groove is circular.
Alternatively, described spew groove is H in the distance of longitudinal direction and described blade die cavity, and described H is 10-20cm.
Alternatively, described H is 15cm.
The beneficial effects of the utility model:
Composite material blade mould of the present utility model, the spew groove with ft connection is provided with along the exhibition of blade die cavity to direction between the die joint and the die joint of counterdie of patrix, the glue unnecessary when blade solidifies flows out along spew groove, thus ensure that blade quality, improve the qualification rate of product.
Accompanying drawing explanation
Fig. 1 is the stereogram of the utility model paddle molding mould;
Fig. 2 is A-A sectional view in Fig. 1;
Fig. 3 is the front view of the utility model paddle molding lower mould.
Detailed description of the invention
Below in conjunction with accompanying drawing, the paddle molding mould involved by the utility model is described in further details.
As shown in Figure 1, 2, 3, composite material blade mould of the present utility model comprises patrix 1 and the counterdie 2 of coupling.Blade die cavity 4 is formed between patrix 1 and counterdie 2; In addition, face bonded to each other between patrix 1 and counterdie 2 is die joint 5, and patrix 1 and counterdie 2 all have die joint 5.
The spew groove 3 with ft connection is provided with along the exhibition of blade die cavity 4 to direction between its die joint 5 at patrix 1 and die joint 5 of counterdie 2.The glue unnecessary when blade solidifies flows out along spew groove 3, thus ensure that blade quality, improves the qualification rate of product.Exhibition is to the length direction being often referred to blade, and on the other side is tangential, i.e. the chord length direction of blade.
Spew groove 3 can be positioned on the die joint 5 of patrix 1, also can be positioned on the die joint 5 of counterdie 2, can also be jointly to be made up of the groove on the die joint 5 of patrix 1 and the die joint 5 of counterdie 2.In the present embodiment, spew groove 3 is positioned on the die joint 5 of counterdie 2, ensures that glue can be discharged more smoothly, can also ensure the intensity of patrix 1.
Spew groove 3 can comprise multiple, preferably includes two in the present embodiment, is symmetricly set on longitudinal both sides of blade die cavity 4.In addition, spew groove 3 is along the exhibition of blade die cavity 4 to direction, due to can be similar to the shape of blade die cavity 4, namely arrange along blade die cavity 4 periphery, and at longitudinal direction and blade die cavity 4 (edge, string of a musical instrument direction of blade die cavity 4), to have certain distance be H, H can be 10-20cm, the preferred 15cm of the present embodiment, said structure can ensure that unnecessary glue can be discharged more smoothly, can also ensure the intensity of mould.
Be appreciated that spew groove 3 can be multiple applicable shape, such as its cross section is square, oval, circular, and the present embodiment preferred volume is large and easily discharge the circle of glue.
When blade solidifies, when mould is pressurizeed, make patrix 1 and counterdie tightly 2-in-1, preimpregnate glass cloth, the material such as preimpregnation carbon cloth and preimpregnation crossbeam for the manufacture of blade, unnecessary glue is discharged from the spew groove 3 on blade die cavity 4 side, what whole mould can be made to fit is smooth, matched moulds clearance control is at below 0.1mm, and very even, thus improves the Forming Quality of blade, improve the production qualification rate of product, nor the heat-transfer effect of patrix 1 and counterdie 2 can be affected.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the original prerequisite of the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
