Device and method for assembling mold for forming plastic lens

摘要

A device ( 20 ) for assembling a plastic-lens-forming casting mold includes a gasket clamping mechanism ( 22 ) which clamps a gasket ( 2 ) from its axial direction, a first mold push-in mechanism ( 23 ) which pushes in an upper mold ( 3 ) fitted in an upper open end of the gasket ( 2 ), and a second mold push-in mechanism ( 24 ) which pushes in a lower mold ( 4 ) fitted in a lower open end of the gasket ( 2 ). The gasket clamping mechanism ( 22 ) clamps the gasket ( 2 ) from the axial direction by a gasket-pressing ring ( 34 ) and lower mold ring ( 35 ). The first mold push-in mechanism ( 23 ) pushes the upper mold ( 3 ) into the gasket ( 2 ) by a gasket push-in member ( 58 ). The second mold push-in mechanism ( 24 ) includes a plurality of push pins ( 68 ) and pushes up the lower mold ( 4 ) to push it into the gasket ( 2 ).
