Abstract

The utility model discloses a forming die of a hollow enclosed element of inner grid reinforced composite material, which relates to a forming die of an element of inner grid reinforced composite material. The utility model solves the problem that a hollow enclosed reinforced composite material element with a more complicated structure is difficult to form by the existing forming die. A metal upper die and a metal lower die are vertically and oppositely arranged, a plurality of metal side split dies are arranged between the metal upper die and the metal lower die, a metal outer frame is sleeved at the outer side of the metal side split dies, cavity bodies are formed among the metal upper die, the metal lower die and the plurality of the metal side split dies, a plurality of water-solubility core dies are arranged in the cavity bodies, and the feeding cavities of the hollow enclosed elements are formed among the metal upper die, the metal lower die, the metal side split dies and the plurality of the water-solubility core dies. The utility model realizes the formation of the hollow enclosed reinforced elements with more complicated structures, the formed product is compact with the porosity less than or equal to 1 percent, and the dimensional accuracy is higher. The utility model increases the production efficiency and reduces the cost.

Description

The mould of inside grid reinforced composite material hollow closure member
Technical field
The utility model relates to a kind of mould of inside grid reinforced composite material member.
Background technology
The characteristics of the fiber-reinforced resin matrix compound material member of grid or the composite element close with its structure are innerly to be made up of difform grid in having, these grids and covering are integrated, guaranteed the continuity of fiber, therefore this class formation has higher structure efficiency, high-strength light more and more is subjected to the attention of aerospace field.Traditional grid adds rib component and generally adopts metal die matched-mold forming, autoclave moulding just can realize.But, realize if adopt above-mentioned mould fully then be difficult to for the member of the complicated hollow sealing reinforcement of structure.
The utility model content
The purpose of this utility model is for the composite element that solves the complicated hollow sealing reinforcement of structure adopts existing mould then to be difficult to the problem that realizes, and then a kind of mould of inside grid reinforced composite material hollow closure member is provided,
The technical solution of the utility model is: the mould of inside grid reinforced composite material hollow closure member comprises the metal patrix, the metal counterdie, a plurality of metal side segmental mandrels and metal outer frame, described mould also comprises a plurality of water-soluble core moulds, described metal patrix and metal counterdie are oppositely arranged up and down, be provided with a plurality of metal side segmental mandrels between metal patrix and the metal counterdie, described metal outer frame is enclosed within the outside of a plurality of metal side segmental mandrels, described metal patrix, form cavity between metal counterdie and a plurality of metal side segmental mandrel, described a plurality of water-soluble core mould is arranged in the cavity, described metal patrix, the metal counterdie, form hollow closure member loading chamber between a plurality of metal side segmental mandrels and a plurality of water-soluble core mould.
The utility model compared with prior art has following beneficial effect: the utility model adopts water-soluble core mould to be used for moulding hollow closure member grid, guaranteed the size of interior grid, because water-soluble core mould is soluble in water, so only need to bore a very little fabrication hole after the moulding, just can be with the stripping of mould internal water soluble core.Metal patrix, metal counterdie, metal side segmental mandrel are surrounded as the profile of composite, have guaranteed the precision of product design size.The utility model has been realized the moulding of the composite element of the hollow sealing reinforcement that structure is complicated, and the product that molds is closely knit, voidage≤1%, and dimensional accuracy is also higher.The utility model has also improved production efficiency, has reduced cost, has solved the problem of apparent mass difference and demoulding difficulty in the formed product process simultaneously.
Description of drawings
Fig. 1 is that overall structure master of the present utility model looks cutaway view, and Fig. 2 is that the master of the utility model dismounting water-soluble core mould looks cutaway view.
The specific embodiment
The specific embodiment one: present embodiment is described in conjunction with Fig. 1 and Fig. 2, the mould of the inside grid reinforced composite material hollow closure member of present embodiment comprises metal patrix 1, metal counterdie 2, a plurality of metal side segmental mandrels 3 and metal outer frame 4, described mould also comprises a plurality of water-soluble core moulds 5, described metal patrix 1 and metal counterdie 2 are oppositely arranged up and down, be provided with a plurality of metal side segmental mandrels 3 between metal patrix 1 and the metal counterdie 2, described metal outer frame 4 is enclosed within the outside of a plurality of metal side segmental mandrels 3, described metal patrix 1, form cavity 6 between metal counterdie 2 and a plurality of metal side segmental mandrel 3, described a plurality of water-soluble core mould 5 is arranged in the cavity 6, described metal patrix 1, metal counterdie 2, form hollow closure member loading chamber 7 between a plurality of metal side segmental mandrels 3 and a plurality of water-soluble core mould 5.
The specific embodiment two: present embodiment is described in conjunction with Fig. 1 and Fig. 2, the mould of present embodiment also increases a plurality of bolts 8, the top and bottom of each metal side segmental mandrel 3 all by be installed in that bolt 8 on the metal outer frame 4 is exerted pressure and the shoulder 1-1 that is resisted against metal patrix 1 respectively goes up and the shoulder 2-1 of metal counterdie 2 on.So be provided with, structure is more reasonable.Other composition is identical with the specific embodiment one with annexation.
