PURPOSE:To obtain a plastic lens with extremely high accuracy by the use of a cheap apparatus and in a short cycle time. CONSTITUTION:On a movable side attaching board 1, a spacer block 4, receiving board 5, and movable side mold plate 6 are fixed integrally. On the stationary side attaching board 2, a stationary side mold plate 7 is fixed. Respectively, a movable side core 8 is fitted into the movable side mold plate 6 and a stationary side core 9 is into the stationary side mold plate 7. The movable side core 8 and stationary side core 9 are formed of machineable ceramic with low thermal conductivity. |
