Description
Technical field
The utility model designs a kind of mould, specifically a kind of to be molded twining for inside grid reinforced cylindrical shell structure product
Around mould.
Background technology
With the continuous improvement of the development of aerospace industry, especially space material technological level, Composites Lattice Structure
More and more it is widely applied.Network made of unidirectional composite material intersection can give full play to the superior of composite
Property, design and the constantly improve of manufacturing process is expected to reduce manufacturing cost as early as possible, there is vast potential for future development and huge potential；
The die method of most commonly seen shaping grid is mainly following three kinds：First, soft mould, it is general that this method USAF flies power
Laboratory（USAF Phillips Laboratory）In technological precedence status, and for producing solar energy pole plate, radome fairing
With guided missile adapter, but the method for soft mould also has its shortcoming, and product surface finish is poor, and rib size is unstable, production
Need to rive soft mode after product solidification, cost is higher, will be difficult to take off simultaneously for the bigger structure of the height/width of rib
Mould；Another grid forming method is the mould program using rigid foam open channels.It is similar to soft mode method, fibre bundle and
Resin enters foam groove so as to form network, and foam can be stayed in composite structure；Play the work of heat preservation and soundproof
With can also remove by machinery, chemistry or the methods of heat damage, the major defect of this method is, grid node fiber
Volume content is up to 60%, thus causes rib not a node position fiber content to be 50% at node, and fiber volume fraction is only
For 30%；Under this fiber volume fraction, the performance of network is far below laying forming composite structure；The third side
Method is die method, such as metal pattern, and its shortcoming is that fiber volume fraction is low, and rib height can not be too high, and labor intensity is big etc., but
Advantage is also fairly obvious, i.e. the good stability of the dimension of product, and precision is high.
The content of the invention
In order to solve the above problems, the utility model provides a kind of carbon fiber enhancement resin base composite material network
Part mould, the mould can repeatedly use, and the grid reinforcing rib of shaped article has higher dimensional accuracy and position
Precision, product quality uniformity are good.
In order to achieve the above object, the utility model is achieved through the following technical solutions：
The utility model is a kind of Wound Dies for being molded inside grid reinforced cylindrical shell structure product, including main body mould, core
Mould and external mold, uniform T-slot is set respectively in main body mould both sides, core is assembled by T-shaped piece with main body mould, and external mold is set
Put in the outside of core, for limiting the profile of molded article, set respectively beneficial to molded article flange at the both ends of main body mould
End frame flange, end frame flange on the outside of be provided with end socket.
Further improvement of the utility model is：Positioned at the both ends of the core by locating ring.
The beneficial effects of the utility model are：This kind is molded the Wound Dies of inside grid reinforced cylindrical shell structure product, fits
For being molded the larger-size network of rib, can effectively solve large scale reinforcement network and be not easy to pressurize and be stripped
The problem of difficult.The utility model mould can repeatedly use, and the grid reinforcing rib of shaped article has higher size essence
Degree and positional precision, product quality uniformity is good, is assembled beneficial to the later stage of product.What is used divides valve grid male, suitable for height
The shaping of performance network product；Its point of lobed formula solves the problems, such as that network is difficult to be stripped.The mould at grid node
Tool draws nest and carries out chamfering, increases volume, solves the problems, such as that grid reinforcing rib continuously intersects.

Embodiment
In order to deepen to understanding of the present utility model, the utility model is done further below in conjunction with drawings and examples
It is described in detail, the embodiment is only used for explaining the utility model, and the scope of protection of the utility model is not formed and limited.
As Figure 1-4, the utility model is a kind of Wound Dies for being molded inside grid reinforced cylindrical shell structure product, is wrapped
Main body mould 3, core 7 and external mold 4 are included, uniform T-slot 9 is set respectively in the both sides of main body mould 3, the core 7 is by can
Adjust T-shaped piece 10 to be assembled with main body mould 3, the external mold 4 is arranged on the outside of the core 7, for limiting molded article 1
Profile, the end frame flange 5 beneficial to molded article flange is set respectively at the both ends of the main body mould 3, in the end frame flange 5
Outside be provided with end socket 8, load onto end socket servicing unit by both ends and realize 10 ° of windings, and rise and be compacted during winding laying
Effect, positioned at the both ends of the core 7 by locating ring 6.
The use step of the Wound Dies includes：
（1）Mould is cleared up, assembles mould；
（2）Then the prepreg tape winding of reinforcement is carried out on the muscle groove of core 7 by wrapping machine, and is put close to reinforcement
Upper airfelt beats vacuum bag and carries out pre-compacted；Aforesaid operations so are repeated, until rib winding finishes；
（3）The paving of covering prepreg is carried out close to the outer surface of core 7 again, after mould moved into baking oven consolidated
Change, curing and demolding；
（4）The demoulding order be：External mold 4 is first dismantled, then dismantles both ends end frame flange 5, the surplus processing of product is carried out, adds
Work is complete to dismantle both ends locating ring 6, by remaining part move to winding arbor extraction press take off main body mould 3, finally by core 7 out of product 1 side draw
