Abstract
An optical lens molding apparatus includes a cylindrical mold, a first mold core, a second mold core and a correctional ring. The first and the second mold core have a columnar shape and are disposed inside the cylindrical mold to form a cavity. Furthermore, the first and the second mold core have a planar portion at the end surface facing the cavity. The correctional ring is disposed on the planar portion of the second mold core. The correction ring corrects any face tilting of the molded optical lens due to the tilting of the first mold core. The present invention also provides a precision molding apparatus for forming precision parts.
