Internal supercharging method for composite material multi-rib siding structure cementing forming technology

The invention discloses an internal supercharging method for a composite material multi-rib siding structure cementing forming technology. A multi-rib siding structure includes an upper skin siding (1), wall bodies (2) and a lower skin siding (3), wherein the wall bodies (2) are cemented with the upper skin siding (1) and the lower skin siding (3) through a double faced gel mold (4) secondary cementing forming technology, and the multi-rib siding structure is characterized in that metal core molds (5) are arranged at the inner cavities of the wall body (2) sides of the multi-rib siding structure; a layer of 3 mm thick silicone rubber plate (6) formed after high temperature sulfuration is laid on each of the lower mold surfaces of the metal core molds (5); a layer of 6 mm thick swelled rubber plate (7) is laid on each of the upper mold surfaces of the metal core molds (5); after all the inner cavities of the wall body (2) sides of the multi-rib siding structure are subjected to the processes, entire heating is performed, when the temperature rises, the swelled rubber plates (7) swell to press flange areas of the wall bodies (2) to enable the wall bodies (2) to be glued to the upper skin siding (1) and the lower skin siding (3) in a clinging manner, and finally demoulding is performed after natural cooling and solidification of gel molds. According to the method, as the pressed assembly is adopted, all the wall body parts are accurately supported, as a result, the outline requirement of the cementing parts is met and the cementing quality is guaranteed.
