Abstract
The invention discloses a demoulding method of a radome structure, which comprises the following steps of 1) paving and attaching an inner skin of a radome on a mould, and fixing a telephone; 2) a plurality of through holes are uniformly formed in the surface of the inner skin, so that air enters between the inner skin and the mold, a certain gap is formed, and the pre-demolding of the inner skin and the mold is realized at first; 3) sleeving the demolded inner skin on the mold again, filling the through hole in the step 2 by using liquid resin, sequentially sleeving the honeycomb interlayer and the outer skin on the mold wrapped with the inner skin, and fixing the phone; 4) after the fixation is finished, the radome is subjected to overall demolding, so that a good demolding effect is achieved, and the problem that normal demolding cannot be easily caused due to the fact that the inner skin and the mold are stuck too tightly in the demolding method adopted at present is solved.
Description
Technical Field
The invention relates to the technical field of radar antenna covers, in particular to a demolding method of a radar antenna cover structure.
Background
Along with the difference of radome application field, the radome parameter that needs, the shape is also diverse, in radome manufacturing process, the drawing of patterns method that adopts at present leads to can not normally drawing of patterns owing to pasting between interior covering and the mould too tightly easily, if carry out the drawing of patterns by force, can cause radome's damage, consequently, need provide a drawing of patterns method of radome structure, can realize radome and demold in advance in the forming process, then accomplish follow-up shaping and whole drawing of patterns smoothly.
Disclosure of Invention
The technical problems solved by the invention are as follows: the demolding method of the radome structure is used for solving the problem that normal demolding cannot be easily caused due to the fact that the inner skin and a mold are stuck too tightly in the existing demolding method.
The technical scheme of the invention is as follows:
a demolding method of a radome structure comprises the following steps:
step 1: and paving and adhering an inner skin of the radar antenna housing on the mould, and then curing.
Step 2: after curing is finished, uniformly forming a plurality of through holes on the surface of the inner skin, enabling air to enter between the inner skin and the mold, forming a certain gap, and firstly realizing the pre-demolding of the inner skin and the mold;
and step 3: sleeving the demolded inner skin on the mold again, ensuring that the inner skin is well attached to the mold, filling the through hole in the step 2 with liquid resin, sequentially sleeving the honeycomb interlayer and the outer skin on the mold wrapped with the inner skin, and curing;
and 4, step 4: and after the solidification is finished, integrally demoulding the radome.
And 2, after the curing is finished, uniformly forming a plurality of through holes on the surface of the inner skin, enabling air to enter between the inner skin and the mold, forming a certain gap, and firstly realizing the pre-demolding of the inner skin and the mold, wherein the diameter of each through hole is not more than 0.5 mm.
And 2, after the curing is finished, uniformly forming a plurality of through holes on the surface of the inner skin, enabling air to enter between the inner skin and the mold, forming a certain gap, firstly realizing the pre-demolding of the inner skin and the mold, and enabling the distance between every two adjacent through holes to be not less than 100 mm.
And 3, sleeving the demolded inner skin on the mold again, ensuring that the inner skin is well attached to the mold, filling the through hole in the step 2 with liquid resin, sequentially sleeving the honeycomb interlayer and the outer skin on the mold wrapped with the inner skin, and curing, wherein the components of the liquid resin are fused with the materials used by the inner skin.
The invention has the beneficial effects that: the method for demoulding the radome structure has the advantages that after the inner skin is solidified, a plurality of through holes with uniform intervals are formed in the surface of the inner skin, so that air enters between the inner skin and the mold, a certain gap is formed, the inner skin and the mold are demoulded in advance smoothly, and finally forming and integral demoulding of the radome are realized.

Detailed Description
A demolding method of a radome structure comprises the following steps:
step 1: and paving and adhering an inner skin of the radar antenna housing on the mould, and then curing.
Step 2: after curing is finished, uniformly forming a plurality of through holes on the surface of the inner skin, enabling air to enter between the inner skin and the mold, forming a certain gap, and firstly realizing the pre-demolding of the inner skin and the mold;
and step 3: sleeving the demolded inner skin on the mold again, ensuring that the inner skin is well attached to the mold, filling the through hole in the step 2 with liquid resin, sequentially sleeving the honeycomb interlayer and the outer skin on the mold wrapped with the inner skin, and curing;
and 4, step 4: and after the solidification is finished, integrally demoulding the radome.
And 2, after the curing is finished, uniformly forming a plurality of through holes in the surface of the inner skin, enabling air to enter between the inner skin and the mold, forming a certain gap, firstly realizing the pre-demolding of the inner skin and the mold, and enabling the diameter of the through holes to be not more than 0.5mm in order not to influence the overall bearing capacity and the structural integrity of the radar antenna cover.
And 2, after the curing is finished, uniformly forming a plurality of through holes in the surface of the inner skin, enabling air to enter between the inner skin and the mold, forming a certain gap, firstly realizing the pre-demolding of the inner skin and the mold, and enabling the distance between every two adjacent through holes to be not less than 100mm in order not to influence the overall bearing capacity and the structural integrity of the radar antenna cover.
And 3, sleeving the demolded inner skin on the mold again, ensuring that the inner skin is well attached to the mold, filling the through hole in the step 2 with liquid resin, sequentially sleeving the honeycomb sandwich layer and the outer skin on the mold wrapped with the inner skin, and curing, wherein the components of the liquid resin are fused with the material used by the inner skin, so that the resin and the resin used by the inner skin are the same material optimally in order to avoid chemical reaction between the resin and the skin for damaging the structural joint.
