The present invention relates to a mold for manufacturing contact lens. The mold of the present invention manufactures contact lens by the following steps: injecting a molding liquid into a convex mold section (201) of a lower mold (200); descending a concave mold section (101) of an upper mold (100) to the lower mold (200) to assemble; and coagulating the molding liquid (10). The concave mold (100) is defined as a ring-shaped outer circumferential surface of the mold disposed outside the concave mold section (101), and includes a side surface insertion unit (103), a region inserted into the lower mold. The lower mold (200) is defined as a ring-shaped inner circumferential surface of the mold disposed outside the convex mold section (201), and includes a side surface accommodating unit (203), a region into which the side surface insertion unit (103) of the upper mold (100) is inserted. In the mold of the present invention, a molding space (32), and molding liquid discharging spaces (34) are included, and a plurality of guide pins (210) are formed to be extended upward along the edge of the lower mold (200) at a fixed interval. The molding space (32) is defined between the concave mold section (101) of the upper mold (100) and the convex mold section (201) of the lower mold (200) while the upper mold (100) and the lower mold (200) are assembled. The molding liquid discharging spaces (34) are defined between the side surface insertion unit (103) and the side surface accommodating unit (203). |
