Bag, the vacuum bag is then vacuumized in hydraulic pressure, after vacuumizing, checks the air-tightness of the vacuum bag；
4) resin and demoulding are imported: importing resin from diversion pipe, sloughs vacuum bag after solidified resin, by cured resin
Demoulding is to be post-processed.
Wherein, the release agent is polyvinyl alcohol release agent.
Wherein, gel coat coating twice is brushed, the gel coat with a thickness of 0.4~0.6mm is obtained.
Wherein, the waterproof compartment is OPP polybag.
Wherein, including ager, hydraulic pressure is provided by the ager, the ager is divided between the first interval and second
Every first interval is respectively equipped with waterproof compartment in interior and described second interval, and the opening of the waterproof compartment is stretched out respectively
First interval and second interval, described first is equipped at intervals with the first pumping that water body in it is pumped to second interval
Water pump, described second is equipped at intervals with the second suction pump that water body in it is pumped to the interval transmission water；In application, will be wait press
Mold is placed in the waterproof isolation pocket at the first interval, and then the water body in second interval is evacuated in first interval
To which the waterproof compartment to be compacted, and then make to be compacted to compression mould；When being compacted when compression mould again, this is waited for that compression mould is put
It sets in the waterproof isolation pocket at the second interval, the water in first interval is then evacuated to second interval thus will be described
The compacting of waterproof compartment, and then make to be compacted to compression mould.
Wherein, the hydraulic pressure of the ager is 5~10MPa.
Wherein, the compacting time to compression mould in the waterproof isolation pocket is 30~60s.
Wherein, the mold is placed 6~8 hours to dry it thoroughly.
Beneficial effects of the present invention:
The present invention utilizes the mobility and pressure of water, can quickly and evenly be laid with compacting surface felt, layers of reinforcement, take off
Mould cloth, diversion pipe, and then avoid and cause product the problem of spot occur because being laid with unevenness in the prior art, substantially increase production
The qualification rate of product；It is equally that vacuum bag is compacted using the mobility and pressure of water, when can not only vacuum bag be prevented to be evacuated
It is damaged the efficiency for also improving and vacuumizing to influence air-tightness, conducive to the production efficiency for improving product.
