OPTICAL TOOL ASSEMBLY FOR IMPROVED RCW AND LENS EDGE FORMATION.

摘要

An optical tool assembly for use in an injection molding apparatus opposite a non-optical tool assembly to form an ophthalmic mold section including a cavity ring mounted to an associated mold plate and an optical insert removably secured to the cavity ring and having an optical molding surface thereon for forming an optical surface of the ophthalmic mold section. The optical molding surface has a right cylindrical wall (RCW) molding portion for forming a RCW of the ophthalmic mold section. The RCW molding portion is formed adjacent a peripheral edge of the optical insert.
