Abstract:
PROBLEM TO BE SOLVED: To provide a molding apparatus which, regardless of the kind of a molding material, can easily mold a pipe with projections.SOLUTION: A molding apparatus comprises: an upper mold 10 and a lower mold 20 having molding surfaces 17a to 17c, 18a to 18c, 27a to 27c, and 28a to 28c corresponding to outer side surfaces of a pipe with projections; a moving mechanism which moves the upper mold 10 and the lower mold 20 so as to define a molding space for molding the pipe with the projections between the molding surfaces 17a to 17c, 18a to 18c, 27a to 27c, and 28a to 28c of the upper mold 10 and the lower mold 20; and a gas supply part which expands a molding material 100 by supplying gas to the molding material 100 serving as a base for the pipe with the projections. The control part controls movement of the upper mold 10 and the lower mold 20 by the moving mechanism and gas supply to the molding material 100 by the gas supply part so that the molding material 100 can be molded to the pipe with the projections in the molding space.SELECTED DRAWING: Figure 10
