The aircraft air inlet channel forming die comprises a special-shaped hollow cylindrical body, the cylindrical body is formed by fixedly connecting a plurality of sheet-shaped core dies, and the side face of each sheet-shaped core die and the side face of the adjacent sheet-shaped core die are provided with connecting and fixing holes matched with each other; the sheet-shaped core molds are mutually attached and fixed through the side faces to form a barrel-shaped body with the smooth surface. According to the sectional type cylindrical air inlet channel mold, all the sections are mutually combined and assembled through the sheet-shaped core molds, the single sheet of each sheet-shaped core mold is small in size and light in weight, and the working efficiency during assembly and disassembly can be effectively improved; and meanwhile, the special-shaped hollow cylindrical body can greatly reduce the weight of the mold, and the problems of deflection deformation and the like of the mold caused by overweight can be effectively avoided in the subsequent process of the mold, so that the precision of the mold is improved.

    本发明公开了一种飞机进气道成型模,包括异形中空的筒状本体,所述筒状本体由若干片状芯模相互固定连接而成,每片片状芯模的侧面与相邻的片状芯模侧面均开设有相互配合的连接固定孔;若干所述的片状芯模之间通过侧面相互贴合固定形成表面光滑的筒状本体;本发明为分段式的筒状进气道模具,其中每段由片状芯模相互组合装配,片状芯模单片的体积小、重量轻,能有效地提高组装、拆卸时的工作效率;同时,异形中空的筒状本体,能大幅度减轻模具的重量,对模具后续的工序当中,可以有效地避免重量过重而产生的模具挠度变形等问题,从而提高模具的精度。
