Abstract

A process of monoblock forming lens seat, which comprises: step 1: forming a lens in which the lens body is installed with two corresponding locating parts; step 2: inserting the lens on the female mold so that the protruded insertion parts of the female mold corresponds to the locating parts of the lens to fix the lens on the female mold; step 3: installing at least one vacuum passageway on the female mold in which one end of the passageway stops at the location where the female mold contacts the lens, and the other end of the passageway connects with a vacuum pump so that the vacuum pump generates a vacuum in the vacuum passageway to suck the lens on the female mold; step 4: moving the male mold toward the female mold, infusing raw material into the mold cavity formed by the female mold and the male mold in order to form a monoblock lens frame at pre-determined location on circumference of the lens; step 5: separating the female mold and the male mold to perform the operation of removing the lens seat from the mold.
