<p>The invention discloses to a pressing molder, relative production of its pressure head and optical element. Wherein, when pressing the molding mould, first, using the first pressure head (11) to compress the main body mould (4) on the support surface (23) (reference surface) of flange (22) of lower mould (2), to process the positioning between the main body mould (4) and the lower mould (2); withsaid positioning state, using the second pressure head (12) to support the upper mould (3) to compress and mold the molding blank (w); when the molding blank (w) is pressed molded, non-incline fixingthe main body mould (4) and lower mould (2) and fixing the first pressure head (11), therefore, the second pressure head (12) that guided by the first pressure head (11) can non-incline compress upper mould (3), and the relative incline between upper and lower moulds (3, 2) can be restrained; the invention can be used to produce the optical element with high shape accuracy.</p> |
