Embodiment Construction
[0045] The present invention will be described in detail below in conjunction with the accompanying drawings and examples.
[0046] Such as figure 1 As shown, the rib-skin structure composite shell forming mold with inner flanged windows includes a core mold 1, a male film 2, an outer female mold 3, an upper pressure ring 4 and a lower pressure ring 5. The male mold 2 is composed of a plurality of split units, the inner surface of each split unit is fixedly connected with the mandrel 1, and the split line 10 of two adjacent split units intersects with the radius 9 of the mandrel where it is located, as figure 2 shown. The split unit forms an outward pressure during the thermal expansion process to ensure that pressure is applied to the window, ribs, skin, and thickening areas of variable thickness to ensure the internal quality of the product. Consistent with the shape of the composite material component to be produced, the molding die described in the present invention can...
