Manufacturing device of composite I beam and manufacturing method of manufacturing device

The invention relates to a manufacturing device of a composite I beam and a manufacturing method of the manufacturing device, and belongs to the technical field of composite part manufacturing. The manufacturing device of the composite I beam comprises a metal male die, swelling rubber male dies, metal baffles and a metal female die; the metal male die is consistent with the inner profile of the composite I beam; composite laying layers are laid on the metal male die and are used for forming an I beam rudiment; the swelling rubber male dies are placed in the compacted composite laying layers, and are used for supporting the composite laying layers and providing pressure during forming; and the metal baffles and the metal female die are placed at the exteriors of the composite laying layers and are used for locating the profile of the composite laying layers. The manufacturing device has the following advantages that the profile of the composite I beam is precisely controlled; no high energy consumption autocl
