Abstract

The invention discloses an integrated forming mold for a main beam box body structure of an unmanned aerial vehicle. The integrated forming mold comprises a main body forming tool, a plurality of positioning tools for prepreg layering, a pair of metal positioning tools for curing, an expandable core mold, and a plurality of conformal pressure equalizing plates, wherein a plurality of first positioning holes are formed in the main body forming tool, each positioning tool for prepreg layering for positioning is positioned and installed on an adapting unit during layering, each adapting unit is positioned in the corresponding first positioning hole, the pair of metal positioning tools for curing are arranged on the left side and the right side of the main beam box body structure of the unmanned aerial vehicle, each metal positioning tool for curing is fixedly connected with the corresponding adapting unit, the metal positioning tools for curing are used for curing and positioning the leftside and the right side of the main beam box structure of the unmanned aerial vehicle under the action of an external force, the expandable core mold is used for forming an inner cavity of the main beam box body structure of the unmanned aerial vehicle, and when the main beam box body structure of the unmanned aerial vehicle is integrally cured and formed through an autoclave process, the plurality of conformal pressure equalizing plates are arranged on the surface of the main beam box body structure of the unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the technical field of manufacturing unmanned aerial vehicle load-bearing structural parts, in particular to an integrated molding mold for the main beam box structure of the unmanned aerial vehicle. Background technique [0002] Long voyage, light weight, low cost, high maneuverability, high security, high concealment and other characteristics are the salient features of drones, and they are also the future development direction of the new generation of drones. The above-mentioned characteristics of the UAV mainly depend on its structural form and the selection of materials, and the composite material mainly composed of carbon fiber is undoubtedly the best choice. Carbon fiber composite materials have the characteristics of light weight, high strength, low thermal expansion coefficient, and fatigue resistance. Using them in the load-bearing structure and other components of drones can achieve effective weight reduction. At pr...
