Patent ID: 8647107

Claim:
A die for manufacturing ceramic products, comprising a first half-die ( 1 ) and a second half-die ( 2 ) located opposite one another, the first half-die ( 1 ) comprising a support ( 6 ); a plate ( 7 ) fixed to the support ( 6 ) which deforms and distributes a pressure exerted by said second half-die ( 2 ) on said ceramic product, said plate ( 7 ) exhibiting a peripheral portion and a central portion ( 7 b ); a chamber ( 8 ) afforded between said support ( 6 ) and said plate ( 7 ) for containing an operating fluid and enabling deformation of said plate ( 7 ), said peripheral portion ( 7 a ) exhibiting an elastic deformability which is greater than an elastic deformability of the central portion ( 7 b ); characterised in that said plate ( 7 ) exhibits a smaller thickness in the peripheral portion ( 7 a ) of said plate ( 7 ) than the thickness of the plate ( 7 ) in the central portion ( 7 b ) thereof; said thickness further being variable progressively from the peripheral portion ( 7 a ) to the central portion ( 7 b ); said plate ( 7 ) exhibiting a surface ( 7 c ) opposite said support ( 6 ), said surface ( 7 c ) being convex at least in said central portion ( 7 b ).
