Description

Technical Field

[0001] The utility model relates to the technical field of aircraft molding, in particular to a flap aileron component molding tool. Background Art

[0002] The aircraft soars in the sky, relying on the wings to generate lift. In addition to the basic wings, there are various auxiliary parts on it, such as ailerons, flaps, leading edge slats and spoilers, etc. These auxiliary parts are used to control the flight attitude, increase lift, increase the critical angle of attack, and improve safety. At present, when manufacturing flap aileron assemblies, it is necessary to first make the upper skin, lower skin and sandwich frame (composed of beams, end ribs, side strips and core materials), and then glue them together. However, when gluing, the gap between the upper skin, lower skin and sandwich frame is difficult to control, resulting in uneven thickness of the glue layer during curing, which reduces the overall precision and affects the molding quality.
