Description

Technical Field

[0001] The utility model relates to the technical field of demoulding of antenna covers, in particular to a demoulding device for a composite antenna cover containing metal inserts. Background Art

[0002] With the development of electronic technology, radomes used to protect antennas and related electronic equipment from the surrounding environment and factors such as rain, snow, ultraviolet rays and strong winds have been widely used in aviation, aerospace, navigation, national defense, electronics, automobiles, communications and other fields. Since composite radomes containing metal inserts are not only resistant to high temperatures, impacts and corrosion, but also lightweight and have excellent electromagnetic transparency, they can work stably in various harsh environments to efficiently transmit and receive signals, and have become the mainstream trend of radome products.

[0003] The existing radome needs to be produced using a mold, and a demoulding operation is required later; if the inner skin of the radome is too tightly attached to the mold, it is difficult to demould normally; for this reason, the Chinese patent with application number CN201810775412.0 discloses a demoulding method for a radar radome structure, including 1) laying the inner skin of the radome on the mold for curing; 2) evenly opening a number of through holes on the surface of the inner skin to allow air to enter between the inner skin and the mold and form a certain gap, first realizing the pre-demolding of the inner skin and the mold; 3) putting the demoulded inner skin back on the mold, filling the through holes described in step 2 with liquid resin, and then successively putting the honeycomb interlayer and the outer skin on the mold wrapped with the inner skin, and then curing; 4) demoulding as a whole. This method has a good demoulding effect, but it is only applicable to radomes with a relatively small aspect ratio and a step-by-step molding inner skin-honeycomb interlayer-outer skin, and cannot be used for composite radomes that are integrally molded and contain metal inserts.
