Embodiment

Certain special-shaped composite foam layer product 5 uses 1 exterior skin, 1,1 foam core 2 and two as shown in Figure 1 Individual dividing plate (obturage dividing plate 3, connecting partition 4) splicing is molded with, wherein the wedge angle and circle that are glued in foam core and exterior skin Arc region needs filling-foam glue J-118, it is ensured that coordinate gapless between part.

A kind of verification cover plate for the shaping of special-shaped composite foam layer product

The shape phase of the verification cover plate 6 and certain special-shaped exterior skin 1 of composite foam layer product 5 as Figure 2-3 Match somebody with somebody, the inner profile for verifying cover plate 6 is consistent with the inner profile of exterior skin 1, and the wedge angle and circular arc sector on the verification cover plate 6 are equal Laying has installed several through holes 7, and the aperture of through hole 7 is 2.5mm, and the spacing of adjacent through-holes 7 is 5mm, and the verification cover plate 6 is vulcanization Rubber verifies cover plate 6, and thickness is 0.2-0.5mm.

A kind of preparation method of the verification cover plate for the shaping of special-shaped composite foam layer product

Comprise the following steps:

1) exterior skin 1 is prepared first, and exterior skin 1 is prepared by exterior skin prepreg laying on forming frock;

2) by the pattern CNC cutting of exterior skin 1, and it is pre- to complete verification cover plate frock with the forming frock of exterior skin 1 as formpiston Soak the laying of material;Ensure that verification cover plate 6 is consistent with the inner profile of exterior skin 1.

3) carry out drilling through hole 7 and process in the wedge angle of verification cover plate 6 and circular arc sector.

A kind of method of calibration for the shaping of special-shaped composite foam layer product

Comprise the following steps:

1) pre-assembled, in dividing plate and the surface mount glued membrane of foam core 2, by exterior skin 1, foam core 2 and baffle combination It is fixed, and wedge angle and circular arc sector filling-foam glue between exterior skin 1 and foam core 2;

2) verify, replace exterior skin 1 using cover plate 6 is verified, with foam core 2 and baffle combination, it is ensured that integral outer chi It is very little to meet digital-to-analogue requirement, then using the occupied state of foamed glue on the observation foam core 2 of through hole 7 verified on cover plate 6.If hair Bubble glue is fitted closely with verification cover plate 6, then prove foam core 2 herein and the verification no-float of cover plate 6;If in the presence of between cooperation Gap, then carry out trickle filling up or cutting down, it is to avoid repairing is excessive, then reuses verification cover plate 6 in relevant position to foamed glue Verification, untill foam core 2 coordinates gapless with verification cover plate 6;

3) after verification is finished, verification cover plate 6 is removed, exterior skin 1 is fixed with foam core 2, baffle combination again.

4) prefoam is verified again, in order to prevent foam core 2 and exterior skin 1 to be glued, before prefoam outside foam core 2 One layer of non-porous release film is wrapped up at position of the surface without foamed glue, and exterior skin 1 is fixed with foam core 2, baffle combination again then After be packaged, enter tank, make foamed glue temperature be 70-80 DEG C carrying out prefoam, then repeat step 2) carry out school again Test, check the harmony coordinated between each part after foaming, if cooperation is bad to carry out trickle finishing to foamed glue again.

5) finally verification cover plate 6 and foam core 2 and baffle combination are replaced using exterior skin 1, it is ensured that overall outer dimensions Meet digital-to-analogue requirement.

Because verification cover plate 6 and exterior skin 1 are prepared on same forming frock, the two inner profile is consistent, therefore foam The matching relationship of fuse 2 and verification cover plate 6 also reflects the matching relationship between foam core 2 and exterior skin 1 indirectly, by foaming The increase and decrease assembly relation and bonding quality final to ensure such sandwich of glue loading.
