Description
Technical field
The utility model belongs to machining class technology, particularly a kind of paddle molding mould.
Background technology
Composite material blade is the requisite part product of helicopter rotor system, and mould manufactures the important frock of producing composite material blade, and 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, it is an often uncared-for problem that mould opens mould, blade is caused to open mould after shaping more difficult, relatively more conventional method makes upper die and lower die separately by compulsory mode, thisly open mould mode operating difficulties, workload is large, and danger coefficient is large, and easily cause blade to be out of shape and blade surface of damaging opening in mold process, thus reduce the qualification rate of product.
Utility model content
The technical problems to be solved in the utility model: a kind of paddle molding mould is provided, the problem that during to solve existing mold depanning, blade is easily out of shape and blade surface is easily damaged.
The technical solution of the utility model:
A kind of paddle molding mould, comprise the upper die and lower die of coupling, the face of described upper die and lower die joint is die joint, described patrix vertically runs through offering at least four screwed holes, and described four screwed holes are evenly distributed on two described die joints relative on described patrix; Be provided with in each described screwed hole one match open mould bolt, described in open mould bolt length be greater than the thickness of described patrix.
Alternatively, position corresponding with at least four described screwed holes on the described die joint of described counterdie offers at least four cylindrical recesses, opens the mould diameter of bolt described in the diameter of described groove is greater than.
Alternatively, described screwed hole comprises four, is evenly distributed on two described die joints on described patrix length direction.
The beneficial effects of the utility model: paddle molding mould of the present utility model; four bolts hole are designed in the both sides of mold; when opening mould, patrix is constantly extruded counterdie by four bolts on mould; thus the speed opening mould can be controlled preferably; upper die and lower die are slowly separated; reach the object of Qi Mo; the utility model is easy to operate, workload is few and security performance is high; blade is not easy distortion and blade surface is not easy to damage; ensure that the quality of blade, improve production qualification rate.

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 Fig. 1,2,3,4,5,6, paddle molding mould of the present utility model, comprise patrix 5 and the counterdie 4 of coupling, the face of patrix 5 and joint, counterdie 4 both sides is die joint 6, runs through to be fixed between patrix 5 and counterdie 4 by multiple pressurization bolt 2 be evenly arranged.
Patrix 5 vertically runs through and offers at least four screwed holes 8, four screwed holes 8 and be evenly distributed on two die joints 6 relative on patrix 5.Particularly, in the present embodiment, preferred screwed hole 8 is four, is evenly distributed on two die joints 6 on patrix 5 length direction, is namely arranged symmetrically with between two.
Be provided with in each screwed hole 8 one match open mould bolt 1, the length opening mould bolt 1 is greater than the thickness of patrix 5, preferably opens the twice that mould bolt 1 length is patrix 5 thickness in the present embodiment.During molding, pressurization bolt is all unsnatched, open mould bolt 1 withstand on the die joint 6 of counterdie 4 by rotating on patrix 5 equally distributed four again, allow counterdie 4 slowly and reposefully away from patrix 5, reach preliminary molding, because of opening the too fast of mould speed, the situation forcing to open in mold process blade of damaging by suspension ring 3 can not be avoided.After completing preliminary molding, crane can be adopted to hook suspension ring 3 on patrix 5 and counterdie 4 by patrix 5 and counterdie 4 quick separating according to traditional method.
Further, on the die joint 6 of counterdie 4, the position corresponding with at least four screwed holes 8 offers at least four cylindrical recesses 7, the diameter of groove 7 is greater than and opens mould bolt 1 diameter, and match with above preferred embodiment, in the present embodiment, preferred cylindrical recesses 7 is four.During molding, open when mould bolt 1 arrives the die joint 6 of counterdie 4 and can enter this four cylindrical recesses 7, only the bottom surface of cylindrical recesses 7 is extruded during mould 4 under extrusion, and die joint 6 can not be damaged.Finally making patrix 5 and counterdie 4 slowly separate, reach the effect of Qi Mo, because of opening the too fast of mould speed, and blade can not be damaged.
Paddle molding mould of the present utility model can according to the product of different shapes, choose reasonable opens quantity and the position of mould bolt 1, thus control or open in mold process after avoiding blade curing molding the situation of blade of damaging, and easy to operate, workload is few and safe etc. advantage.In addition, paddle molding mould structure of the present utility model is simple, easy to operate, good stability, be applicable to producing in enormous quantities and problem beforehand research model paddle development type, thus shorten part open the mould time, improve the security of operator and the quality of product, improve the production qualification rate of composite material blade of helicopter.
The above is only preferred embodiment of the present utility model, it should be pointed out that for those skilled in the art, and do not departing under the original prerequisite of the utility model, these improvements and modifications also should be considered as protection domain of the present utility model.
