Description
Technical field
The present invention relates to air equipment field, the especially a kind of molding die and plate of part autoclave molding.
Background technique
In air equipment field, traditional metal material performance is gradually unable to satisfy higher and higher design requirement.Carbon
There are fibrous composite traditional metal materials to be difficult to the performance to match in excellence or beauty, therefore be applied on air equipment more and more widely
Part processing.In the prior art, the molding of composite material parts is usually carried out by RTM (resin transfer moulding) technique, this
The drawbacks of kind processing method, is: since in air equipment, design of part is often complex, therefore, using traditional RTM work
Skill, mold manufacture difficulty is higher, so that cost of parts is high, demoulding is also more difficult.
Summary of the invention
Goal of the invention of the invention is: in view of the problems of the existing technology, providing a kind of part autoclave molding
Molding die and plate, to reduce the manufacture difficulty of mold.
To achieve the goals above, the technical solution adopted by the present invention are as follows:
A kind of molding die for part autoclave molding, including die matrix and with the detachable phase of die matrix
Die cover plate even；The forming cavity for accommodating composite material is formed on die matrix, forming cavity is communicated with the outside world by opening；
Die cover plate is adapted to opening, has cover board forming surface on die cover plate, when die cover plate is connected with die matrix, cover board molding
Face is corresponding with forming cavity, and forming cavity is separated with the external world, and the shape and part of forming cavity are coincide.
The technical solution used through the invention places the raw material of composite material, then in processing in forming cavity
Raw material are covered in cover board forming surface, die matrix and die cover plate are mounted together, and carry out autoclave molding, thus
It obtains and the matched part of forming cavity shape.
In addition to aforesaid way, raw material can also be covered in cover board forming surface, are solidified, have been solidified in processing
It is spare at rear demoulding；Then the raw material that composite material is placed in forming cavity, are solidified, and take advantage of in forming cavity composite material also
When softer, raw material sheet is stacked again on the composite material of forming cavity, then by composite material molded on die cover plate
It is covered in raw material sheet, solidifies again to whole.
By that mold can be decomposed into two parts according to the shape of part, to reduce mold with this molding die
Difficulty of processing.Meanwhile using this mold, the solidification order of mold portions can be adjusted according to the different shape of part,
To obtain the part that material property meets technical indicator.
As a preferred solution of the present invention, die matrix include the first profiled sheeting and the second profiled sheeting, the first profiled sheeting with
Second profiled sheeting is detachably connected；There is the first forming surface on first profiled sheeting, there is the second forming surface on the second profiled sheeting；The
When one profiled sheeting is connected with the second profiled sheeting, die matrix forms forming cavity, the first forming surface and the second forming surface and forming cavity
It is corresponding.
Die matrix is decomposed into the first profiled sheeting and the second profiled sheeting, further reduced die matrix, structure is complicated
Degree, to advantageously reduce the difficulty of processing of the molding die.
As a preferred solution of the present invention, die matrix further includes third profiled sheeting；First profiled sheeting one end and third at
Template is detachably connected, and second profiled sheeting one end is detachably connected with third profiled sheeting；There is third on third profiled sheeting
Forming surface, third forming surface are corresponding with forming cavity.
Since the raw material of composite material are laminated structure, when the structure of forming cavity is more complete, to forming cavity
Raw material sheet is added in interior gap, can only be added in such a way that manpower pressurizes, it is difficult to guarantee the material utilization amount in forming cavity
Reach specification, be easy to cause generation material cavity on part.If forming cavity is decomposed into three profiled sheetings, in assembling third molding
Before plate, the first profiled sheeting and the second profiled sheeting are first connected, is placed in the space that the first profiled sheeting and the second profiled sheeting surround former
Then material piece covers enough raw material sheets in third forming surface, third profiled sheeting is finally connected to the first profiled sheeting
On the second profiled sheeting, this mode, which advantageously ensures that, adds enough raw material sheets in forming cavity, to guarantee part
Material property.
Specifically, the position of third profiled sheeting can be configured according to the concrete shape of part, and particularly, third molding
Plate can be close to the more position of the wedge angle of part or close to lesser end face, so that being covered on the former material in third forming surface
Tablet can be used for the lesser gap on filling molding chamber.
As a preferred solution of the present invention, die matrix is equipped at least two first positioning regions, and die cover plate is equipped with
The second positioning region being adapted to the first positioning region.
First positioning region is set on die matrix, the second positioning region is set on die cover plate, can guarantee die matrix
With die cover plate each time using being that relative position is able to maintain fixation.
As a preferred solution of the present invention, die matrix and/or die cover plate are equipped with reinforcing rib.
For larger-size part, reinforcing rib is set on die matrix and/or die cover plate, helps avoid mold
Matrix and die cover plate deform during autoclave molding.
A kind of plate, plate are obtained by carbon fiber autoclave molding, and plate is process by above-mentioned molding die.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
1. carrying out the autoclave molding of carbon fibre composite part using molding die provided by the invention, can help
The processing of part in irregular shape is particularly suitable for reduce cost in the difficulty of processing for reducing mold；
2. the processing of carbon fibre composite part is carried out using molding die provided by the invention, it can be according to part
Shape uses different solidifications and profiled sheeting built-up sequence, and then the Forming Quality of part is made to meet the requirements.
