This molding die used for molding a composite material comprises: a molding member having a molding surface; a support frame that is provided on the lower side of the molding member, and that supports the molding member; and a height adjustment mechanism that is provided between the molding member and the support frame, and that is capable of adjusting the height of the molding member with respect to the support frame. The thermal expansion coefficient of the molding member is less than or equal to the thermal expansion coefficient of the support frame. Three wheels that travel on a floor surface while supporting the support frame at three points are provided on the lower side of the support frame.

Molding die and method for molding composite material

In the manufacturing method of the present invention, as preparation for providing a moldwith protrusionsandto be printed on an FRP material of a skinin co-bold molding, which requires resetting of the skinto the mold, a long protrusionA and a short protrusionB are interchangeable as one protrusion. The long protrusionA is printed to form a second recessed partin the skin, and before the skinis reset, the long protrusionA is replaced with the short protrusionB. In this way, as the short protrusionB is housed in the second recessed partformed during elongation of the mold, the skincan be reset in the state of being positioned relative to the moldby the first protrusionand the short protrusionB.
