METHOD FOR MANUFACTURING CERAMIC MOLDED COMPONENT, MOLDING DIE USED IN THE METHOD AND CERAMIC COMPONENT

摘要

A lower periphery constraint portion [[(15)]] and an upper periphery constraint portion [[(16)]] for molding the periphery of a lens as well as a mirror-finished optical molding surface [[(3a)]] and another mirror-finished optical molding surface [[(9a)]] are formed on a lower mold body [[(3)]] and an upper mold body [[(9)]] of a mold [[(1)]] respectively. The upper periphery constraint portion [[(16)]] and the lower periphery constraint portion [[(15)]] are so formed as to have prescribed thicknesses alpha1 and alpha2 in a pressure axis direction respectively. A periphery nonconstraint portion [[(17)]] not constraining ceramics when molding a ceramics material is provided between the lower mold body [[(3)]] and the upper mold body [[(9)]]. 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.
