Method of manufacturing ceramics molded component and mold employed therefor as well as ceramics component

摘要

A lower periphery constraint portion and an upper periphery constraint portion for molding the periphery of a lens as well as a mirror-finished optical molding surface and another mirror-finished optical molding surface are formed on a lower mold body and an upper mold body of a mold respectively. The upper periphery constraint portion and the lower periphery constraint portion are so formed as to have prescribed thicknesses α1 and α2 in a pressure axis direction respectively. A periphery nonconstraint portion not constraining ceramics when molding a ceramics material is provided between the lower mold body and the upper mold body. Thus, a ceramics molded component or the like is prevented from breakage and can be easily detached from the mold, so that the same can be more homogeneously densified.
