Description
Technical field
The utility model is related to technical field of vacuum, more particularly to a kind of carbon fibre composite vacuum bag assembly.
Background technology
Carbon fibre composite is taken out from refrigerating chamber after defrosting, according to the shape of product, specification requirement laying in mould
On, form certain shape, structure；Product now needs to carry out heat-shaping processing under vacuum, to improve carbon
The mouldability of fibrous composite.
Traditional carbon fibre composite vacuum pumping method is that the carbon fiber under sealing state is answered by vacuum nozzle
Condensation material carries out vacuumize process.Its sealing means is by carbon fibre composite laying on mould, then with diaphragm seal by mould
Tool sealing.This sealing uses the close envelope mode in scene, there is the weak point of processing time length；In addition, by diaphragm seal
Sealed with mould, during practical operation, easy gas leakage is, it is necessary to multilayer, multiple encapsulation process.
When vacuumizing, due to the direct relative vacuum bag in the bottom of vacuum nozzle, the air-flow in vacuum bag is taken out in disordered state
Go out, can cause to vacuumize the deficiency that efficiency is low, vacuumizing effect is poor.
In order to improve the air guide of vacuum nozzle, air slot can be set in the bottom of vacuum nozzle.But, due to Jie of air slot
Enter, when vacuumizing, diaphragm seal can be adjacent in the edge of air slot, and vacuum nozzle is metal material, modulus is larger, can cause close
Sealer is cut, it is impossible to carry out normal vacuumize process.
The method that prior art solves the problem is by setting multi-layer sealed film or using such as polyimides or fluorine modeling
Expect that contour performance materials prepare diaphragm seal, the phenomenon that diaphragm seal is cut is reduced by improving the thickness or performance of diaphragm seal.
But, this method can bring behaviour to do trouble on diaphragm seal sealing part, and also improve processing cost；In addition, simple
The plan of establishment of multi-layer sealed film not can solve broken bag problem.
