OPTICAL TOOL ASSEMBLY FOR IMPROVED RCW AND LENS EDGE FORMATION

摘要

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