Foundry goods blank process on Digit Control Machine Tool.Install a mold into during work on stretching-machine,
Then clamping tablet, starts stretching-machine, makes tablet be close to die forming surface and progressively by pulling force
Extend to specify position, complete the shaping of part, but have the drawback that first, manufacture zero
Part limited amount, after reason is a few task, due to frictional force between die surface and tablet
Impact, residue can be produced, be trapped in die surface, it is extremely difficult to cleaning, make piece surface produce
Raw cut even scratches, and causes part rejection；Secondly, Making mold difficulty is big, and reason is
Die forming surface must not be defective, such as pore, sand holes, machining spur etc., once finds,
I.e. it is likely to result in a complete set of mould to scrap；Additionally, mold storing is difficult, when depositing must not corrosion, table
Face absolute prohibition collides with, and finds mould shape planar defect, it is impossible to repair, it addition, of poor quality, greatly
Type part often reaches tens tons, is highly detrimental to carrying.
Summary of the invention
It is an object of the invention to solve the problems referred to above, it is provided that a kind of polymer matrix composites fly
The manufacture method of the pull-shaped mould of machine part, the present invention uses polymer matrix composites to manufacture aircraft
The pull-shaped mould of part, improves mould utilization factor, especially increases part production capacity；Reduce Making mold
Cost, shortens die manufacturing cycle.
For achieving the above object, the present invention adopts the following technical scheme that
The manufacture method of a kind of pull-shaped mould of polymer matrix composites airplane parts, it implements
Step is as follows:
A, with base shape for body core manufacture foam base plate model, with mass ratio as 100:400
Ratio epoxy material and aluminium hydrate powder are mixed into pureed mixture, then by institute
State pureed mixture to stick along described foam base plate model cavity inwall, when thickness reaches 50mm,
Stick layer of glass cloth, steps be repeated alternatively until till base body die die cavity fills up, room temperature
Resin matrix solidified forming after lower solidification 24 hours；
B, with surface configuration for core manufacture foam surface model；
C, by described foam surface model set resin matrix after hardening, at described foam
Running channel and multiple venthole is accomplished fluently, from described running channel in foam surface model above surface model
Pour into resin material, till making foam surface model cavity fill up；
D, ambient temperature curing 24 hours, make surface；
E, Digit Control Machine Tool is utilized to be processed into the pull-shaped mould of airplane parts.
Further, the epoxy material of described step a is SAM910 resin material.
Further, the resin material of described step c is SAM900 resin material.
Further, the pull-shaped mould of airplane parts that described step e is made includes matrix, is positioned at
Surface above matrix and be positioned at the suspension ring of matrix side.
The invention has the beneficial effects as follows:
(1) present invention makes full use of the characteristic of polymer matrix composites, makes mould shape face possess
Self-lubricating function, reduces enhanced stretch resistance, and resin material can be become quality by liquid curing at normal temperatures
Uniform solid material so that die surface hardness uniformity, occurs without scleroma and pore etc.
Phenomenon, reduce Making mold difficulty, make mould possess recoverability simultaneously, to article surface without
Damage.Use glass fiber reinforcement mode, be combined with glass fibre with epoxy material,
Manufacture die matrix, it is achieved that the lightweight of mould, and manufacturing cycle is greatly shortened.
(2) present invention uses polymer matrix composites to manufacture the pull-shaped mould of airplane parts, carries
High mould utilization factor, especially increases part production capacity；
(3) present invention reduces die manufacturing cost, shortens die manufacturing cycle；
(4) mould of the present invention easily repair, easy to store, manufacture process product percent defective is zero,
And achieving lightweight, small product size weight is 1/5th of steel matter product, preferably solves
Determine the carrying problem of mould.

Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with
Drawings and Examples, are further elaborated to the present invention.Should be appreciated that this place is retouched
The specific embodiment stated only in order to explain the present invention, is not intended to limit the present invention.
The manufacture method of a kind of pull-shaped mould of polymer matrix composites airplane parts, it implements
Step is as follows:
A, reference Fig. 1, be shaped as body core with matrix 1 and manufacture foam base plate model 4, by quality
Than the ratio for 100:400, epoxy material SAM910 is mixed into aluminium hydrate powder
Pureed mixture 5, then by described pureed mixture 5 along described foam base plate model 4 intracavity
Wall sticks, and when thickness reaches 50mm, sticks layer of glass cloth 6, repeat the above steps
Until foam base plate model cavity fills up, resin matrix solidification after ambient temperature curing 24 hours
