Description
Technical field
The present invention relates to technical field of composite material manufacturing, in particular to a kind of ten thousand suitable for vacuum aided forming technology
Use mold.
Background technique
In composite material manufacturing field, vacuum aided forming technology has at low cost, suitable large scale, big-thickness structure part
Production, parts quality is preferable, is the more appropriate forming technology of composite products development phase.Vacuum aided forming technology
It is then to be excluded under negative pressure of vacuum in single side rigid die with flexible vacuum bag film coated, sealing fibre reinforced materials
Gas in die cavity realizes the dipping to resin and its fabric using the flowing and infiltration of resin, and in room temperature or fire-bar
A kind of process of solidified forming under part.
Currently, the single side rigid die of vacuum aided forming technology can be divided into according to the requirement of product quality and quantity it is included
The steel die of heating module and fiber reinforced plastic mold without heating module.The repeated multiple times use of steel die is rear indeformable, surely
It is qualitative preferable, but involve great expense, it is suitable for a fairly large number of product of required exemplar；Fiber reinforced plastic mold cost is relatively low, only
The quality that can guarantee preceding product several times, the product suitable for required exemplar negligible amounts.
Such as the patent document of Publication No. CN104772911A discloses a kind of forming of thermoplastic fibre composite material
Method and its shaping dies, which includes: one enters mould step: thermoplastic material and fiber cloth material are placed in the mould of mold
In cave；One vacuum step: the die cavity of the mold is vacuumized, and the fiber cloth material is made to be closely attached on the cavity surface；One
One heating stepses: heating the mold, and the mold temperature is maintained between 80~200 DEG C, allows the thermoplastic material
And fiber cloth material softening；One second heating stepses: persistently heating the mold, and the mold temperature is maintained at 150~
Between 300 DEG C, the thermoplastic material and fiber cloth material is allowed mutually to be bonded to one；One cooling curing schedule: the mold is carried out
Cooling, and the mold is maintained at room temperature, and the time between 15 seconds to 30 minutes, allow the thermoplasticity being mutually bonded to one
Material and the solidification of fiber cloth material, and obtain a finished product；One material step: after die sinking, the finished product of cured completion, user are taken out
Just.
But since fiber reinforced plastic mold reusability is poor, using just scrapping later several times, cause greatly
The wasting of resources.Its structure of the development phase of product and shape are being improved and are being optimized always simultaneously, required exemplar quantity also compared with
It is few, therefore most of product uses fiber reinforced plastic mold in development phase.But every shape for updating primary production just needs weight
Coming of new mold also will cause the waste of resource in the research and development progress for influencing product simultaneously.
