Plastic injection-compression multi-cavity molding of flash-free improved-cleanliness thermoplastic spectacle lenses () are suitable to be robotically dip hardcoated. Special spring-loaded () molds having variable-volume mold cavities are used in an injection-compression molding process to form, without parting line flash, pairs of a wide range of differing optical power of polycarbonate Rx spectacle lenses (). These pairs have special molded-on design features which are specially suited for full automation, starting with a novel way for ejection out of the mold into a takeout robot which is integrated via full automation with subsequent dip hardcoating. A molded-on tab with each pair of lenses is specially suited for manipulation by SCARA type robot. This combination produces micro-clean hardcoated paired molded lens made entirely within a single continuous cleanroom air enclosure surrounding the lenses, without any human operators therein, nor requiring any cutting or trimming of the molded paired lens or runner system before hardcoating, nor use of Freon (tm) CFC nor aqueous cleaning protocols before dipcoating.

A molded disk is transferred out of the mold with short-stroke low-mass motions of a pair of mechanical guides which can grip, then release, the O. D. edge of the molded disk, when acting in coordination with movable mold members having undercuts for molded-on retention of the inner portion of the molded disk and/or sprue. Acting together, the disk is stripped off the molding surfaces and can be oriented in a second vertical plane to freely drop out an aperture in the mold, to exit through a discharge chute. Two ways of separating the sprue from the disk are shown, with a molded-in centerhole being preferred. This method and apparatus for transferring the molded disk out faster by gravity discharge wherein an optical disk mold can be enclosed against airborne dirt throughout molding cycles.

An extension of this cleanroom enclosure and robotic handling scheme may optionally provide in-line continuous-product-flow automatic inspection of optical power and lens cosmetic quality, and/or may optionally provide in-line continuous-product-flow anti-reflective thin film vacuum coating, before the molded-and-hardcoated polycarbonate lenses exit out of the continuous cleanroom air enclosure and/or receive any manual handling.

Method and apparatus for lens thickness adjustment in injection molding of thermoplastic vision-corrective spectacle lenses without manual addition or removal of shims, of inserts or of any other mold part. Thickness adjustment can be made quickly while the lens mold is kept at very hot operating temperatures, yet minimal risk of burning the operator. A rotatable adjustment head is mounted externally onto the mold's operator side, and manually-driven rotation turns a threaded screw which moves one wedge block of a slideably mated pair of opposing wedge blocks in a plane parallel to the parting line, thus moving the opposing wedge block axially forward or back perpendicular to the parting line, but always retaining proper alignment and loadbearing support of optical inserts, even in multicavity injection-compression molding. After many re-polishings of inserts, lens thickness specifications are still maintained without needing shims. This permits use of circulating heat transfer fluids internally within the inserts, to greatly reduce cycle times, yet have minimal fluid leakage problems.

Apparatus for injection compression molding of thermoplastic parts. A preferred apparatus (100) includes a platen assembly 106, a toggle clamp assembly 102, a screw injection assembly 101, a hydraulic system suitable for providing power to the toggle clamp assembly 102 and the screw injection assembly 101, and a control system 88 for operatively controlling the various hydraulic devices associated with the molding apparatus. The platen assembly 106 provides for a plurality of variable-volume mold cavities 7. In one embodiment, enlarged mold cavities 7 receive plasticized resin from the screw injection assembly 101, and compression of the injected resin is provided by the toggle clamp assembly 102. In another embodiment, the platen assembly 106 includes a floating die assembly wherein pressure created by injected resin causes die inserts 5 and support pillars 15 to slide relative to a molding plate 74. Compression in this embodiment is also preferably provided by the main toggle clamp assembly 102.
