Hood heat shield forming tool for returnable spacecraft
A return-type spacecraft and molding tooling technology, which is applied to household components, household appliances, other household appliances, etc., can solve the problem that the heat-proof hood layer of the return-type spacecraft cannot be directly subjected to vacuum impregnation, drying, and curing processes. Avoid the degradation of thermal protection performance, avoid excessive stress, and improve the effect of resin impregnation quality

Embodiment Construction
[0048] Such as Figure 1 to Figure 6 As shown, a returnable spacecraft hood heat-proof layer forming tooling includes a lower mold 11, a middle mold 10, an upper mold 1, an observation window 2, a vacuum gauge 3, a placeholder 4, a vacuum pipeline 5, and a glue injection pipeline 13 , Tray 9, hoisting ring 7, pressing plate 14, pressing frame 6 and guide wheel 12.
[0049] Along the height direction, the tooling is divided into three layers, the upper mold 1, the middle mold 10, and the lower mold 11; The installation surface is in the middle of the height direction of the inner tray 9; the upper mold 1 is used as the upper cover, and after assembly, forms a closed cavity together with the middle mold 10 and the lower mold 11; Install the gasket.
[0050] The lower mold 11 is located at the bottom of the tooling and has a concave mold structure. The distance between the inner wall and the heat-proof layer 8 of the spacecraft hood is 20mm; the lowest part of the inner cavity ...
