Upper and lower edge face；
4) position block is individually positioned in by position, hole, location the both sides of frock main body；
5) gap of position block and frock main body, fixed position block after meeting the requirements are checked
And fit tightly with frock main body；
6) complete the Zone R implant of lower edge face part respectively on " work " font part,
7) successively paving " work " font zero in frock main body with the groove of position block composition
Another " C " type structure of part；
8) in groove, non-metallic pressure pad in another " C " type structure, is placed；
9) make vacuum bag, by the frock that combines with part integral coating in vacuum bag；
10) curing molding；
11) vacuum bag, non-metallic pressure pad, all keepers, position block are removed；
12) by part removal, qualified parts are gone out according to part theory sharp processing.
The shaped device of the present invention possesses following advantage:
1) tool structure is simple, and part manufacturing cost is low: paving, solidification share 1 set frock；
2) position block is fixed in position, axis of workpiece direction, is being perpendicular to axis of workpiece direction
On can be movable within the specific limits, such location mode is capable of resilient engagement.Solid
Changing under pressure, position block can be together with " several " type frock main body fits tightly, part
Between internal each laying the finest and close；
3) 2 " C " type structures molding in same set of frock of " work " font part, work
Assembling structure is simple, process is easy, and matching relationship is few, it is to avoid 2 " C " type structures
To closing operation, shaft parts dimension is accurate；
4) pressure pad can uniform conductive solidifying pressure, inside parts laminating closely, smooth surface；
5) tool structure is simple, and curing and demolding is convenient, will not be because of demoulding injuring part.

Detailed description of the invention
As shown in Figure 3,4, the shaped device of a kind of " work " font part, including " several "
Type frock main body 8, position block 7, non-metallic pressure pad 6.Frock main body 8 is placed in bottom,
One " C " type structure 2 paving of " work " font part is on frock main body 8 surface；Work
Dress main body 8 liang is picked up the ears and the relevant position of position block 7 is provided with hole, location, position block 7
It is fixed on frock main body 8 liang picks up the ears, for paving and the upper limb of location " work " font part
Face 1 and lower edge face 5；Non-metallic pressure pad 6 is placed in " work " font part another " C "
In the groove of type structure 2, for compressing component and uniformly transfer pressure.
As a example by the manufacture of " work " font stringer, as Figure 1-4, concrete forming process is such as
Under:
1) in " several " type frock main body 8, even application releasing agent on position block 7, and
Dry；
2) successively spread along frock projection section profile on " several " type frock main body 8 upper surface
1 " C " type structure 2 of patch " work " font part；
3) on position block 7 on frock one side surface successively paving " work " font zero
The upper limb face 1 of part, lower edge face 5；
4) position block 7 is individually positioned in by position, hole, location the both sides of frock main body 8；
5) gap of position block 7 and frock main body 8, stationary positioned after meeting the requirements are checked
Block 7 also fits tightly with frock main body 8；
6) complete " work " font part 9 upper limb face 1, the R of lower edge face 5 part respectively
District's implant 4,
7) successively paving " work " word in frock main body 8 with the groove of position block 7 composition
Another " C " type structure 2 of type part；
8) in groove, non-metallic pressure pad 6 in another " C " type structure 2, is placed；
9) make vacuum bag, by the frock that combines with part 9 integral coating in vacuum bag；
10) curing molding；
11) vacuum bag, non-metallic pressure pad 6, all keepers, position block 7 are removed；
