In general, molding of a contact lens, after the molding liquid is injected into the molding groove formed in the lower mold, the upper mold is pressed into the molding groove to solidify the molding liquid, and then solidify to be molded in the lower mold and the upper mold. It is produced in order of demolding the contact lens.

In this field, a transfer layer including various shapes or patterns on the surface of the upper mold is formed by stamping, so that various shapes or patterns are produced on the surface of the final manufactured contact lens through the transfer process.

That is, when the upper mold having the transfer layer formed on the surface is pressed into the molding groove of the lower mold into which the molding liquid is injected, the molding liquid injected into the molding groove of the lower mold is formed on the surface of the upper mold during the press molding process through the upper mold. The transfer layer formed in the is formed through the transfer.

In the process of forming the transfer layer on the upper mold, a mold bundle in which a plurality of upper molds are radially disposed on the outer side of the center rod by injection molding is separated by the worker, and then the separated upper mold is separated by the operator. When the worker places the mold on the lower part of the stamp by manual work, the stamp with the dye on the bottom is lowered to form a transfer layer on the upper mold.

In addition, conventionally, a clamp member for fixing the upper mold separated from the mold bundle is installed at one point where the stamp portion with dye is lowered on the bottom surface, so that an operator separates the upper mold from the mold bundle during the driving process of the stamp portion.
