Cooling and shaping, is then stripped, and the carbon fiber product is made.
Preferably, the compression-moulding methods are additionally included in mold cavity bottoms and set stomata, vaccum-pumping equipment are configured, in matched moulds mistake
Vaccum-pumping equipment is vacuumized by the stomata to the die cavity in journey, each position of products made thereby is kissed completely with die cavity
Close.
Preferably, it is respectively provided with the stomata in the corner of die cavity.
Preferably, oil circulation pipe is set in mould, mould heated by oil circulation.
Above-mentioned compression-moulding methods, during matched moulds, the increase with carbon fiber plate to the pulling force of fixture, fixture to
Die cavity center position stretches.
A kind of mould that carbon fiber product is prepared by raw material of carbon fiber plate, the mould includes upper die and lower die, the mould
Tool also includes four fixtures and four elastic devices, and four fixtures are respectively supported at die cavity above lower mould by four elastic devices
Surrounding, the elastic device provides the power for making fixture be moved in the horizontal direction to the direction away from the die cavity.
Preferably, the elastic device is cylinder, and the cylinder body of cylinder is fixed in frame, and fixture is fixed on the piston of cylinder
On bar.
Preferably, mold cavity bottoms set stomata, and stomata connects supporting vacuum equipment.
Preferably, it is respectively provided with the stomata in the corner of die cavity.
Preferably, oil circulation pipe is set in mould, and oil circulation pipe is connected with firing equipment.
Compared with prior art, the present invention at least has the advantages that：
Carbon fiber plate is supported by above-mentioned fixture and elastic device, with lower mould matched moulds process under upper molding
In, elastic device deformation fixture inwardly stretches, and can make after mould matched moulds product thickness uniform whereby, material is not in wrinkle.
Due to realizing heating using oil circulation, it is ensured that mould-cavity temperature is uniform and temperature is up to 150-200 degrees Celsius, reduces carbon fiber
The moulding difficulty of sheet material.By setting stomata in mold cavity bottoms, vaccum-pumping equipment is configured, vaccum-pumping equipment leads to during matched moulds
Cross the stomata to vacuumize die cavity, each position and die cavity for making products made thereby fit like a glove.In addition, the present invention is with carbon fiber
Sheet material be raw material by being molded straight forming, compared to using the moulding rear brush resin glue of fiber cloth forming method, work of the present invention
Skill is simple, and cost is low.
Brief description of the drawings
Fig. 1 is the structural representation of one embodiment mould；
Fig. 2 is its side view；
Fig. 3 is to remove the overlooking the structure diagram after upper mould.
Embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 to Fig. 3 shows a kind of structure for the mould that carbon fiber product is prepared by raw material of carbon fiber plate.Fig. 1 is extremely
In Fig. 3,1 is frame, and 2 be cylinder, and 3 be fixture, and 4 be upper mould drive device, and 5 be upper mould, and 6 be lower mould, and 7 be die cavity, and 8 be gas
Pipe.
Fig. 1 to Fig. 3 is refer to, the mould includes upper mould 5 and lower mould 6, the mould also includes four fixtures 3 and four cylinders
2 (elastic devices), four fixtures 3 are respectively supported at the surrounding of the lower top die cavity 7 of mould 6, more specifically, gas by four cylinders 2
The cylinder body of cylinder 2 is fixed in frame 1, and fixture 3 is fixed on the piston rod of cylinder 2.Cylinder 2, which is provided, makes fixture 3 in the horizontal direction
On to away from the die cavity 7 direction move power.
Using carbon fiber plate as raw material, the method that carbon fiber product is prepared with above-mentioned mould specifically includes following steps：
Four edges of carbon fiber plate (raw material) are clamped with four fixtures 3, carbon fiber plate is horizontally supported at down
The top of die cavity 7 of mould 6；
