Description

Mold cutting device for manufacturing contact lens

The present invention relates to a mold cutting device for manufacturing a contact lens, and more particularly, by automatically cutting only a mold from an injection-molded mold body, and then feeding and feeding the mold, so that mold can be easily supplied and automated uniform cutting. The present invention relates to a mold cutting device for manufacturing a contact lens that can improve quality such as preventing mold defects and damages by work.

In general, contact lenses worn by being put in direct contact with the corneal surface of the eye are used to refract light by refracting light in contact with the corneal surface. In addition, it is widely used as a cosmetic contact lens that can produce a variety of eye colors by implementing colors and designs on contact lenses.

The contact lens has a curved portion that performs an optical function by refracting light at the center corresponding to the wearer's eyes, and the outer surface of the contact lens has a separate curved surface to reduce the overall thickness of the contact lens in order to reduce foreign object feeling during wearing. The part is formed.

Such a contact lens is typically manufactured in a half-molded type, that is, when the monomer used as a raw material of the contact lens is injected into the concave mold and the convex mold is left in the concave mold for a predetermined time, the monomer is cured. The contact lens is attached to the convex mold while forming the shape of the contact lens. As described above, the convex mold in which the monomer is hardened and bound is inserted into the jig of the lathe to cut and polish the convex surface of the contact lens, and then the contact lens is removed from the convex mold. Separately prepared methods are widely used.

In relation to the above manufacturing method, Korean Patent No. 10-0902658 discloses a method of manufacturing a contact lens by injecting a monomer between a concave mold forming a convex outer surface of a contact lens and a convex mold fitted to the concave mold. Corresponding to the concave mold, the fitting groove fitted to the jig of the shelf has a cylindrical shape that is stepped to reduce the diameter in multiple stages, the marking projection is formed on the outer periphery of the bottom of the body, Injecting a convex mold having a convex surface formed according to the same; Marking step of marking the correct position by digging a groove using a drill on one side of the body of the convex mold; Injecting a monomer into a concave mold, pressing the hardened marking convex mold from a convex surface, and pressing and curing the convex mold from the concave mold; Cutting the convex mold into the jig of the lathe to cut the thickness of the contact lens peripheral portion bound to the convex surface of the convex mold to be 0.04 to 0.08 mm; Cutting the upper part including the convex surface of the convex mold through the cutting step using a cutter; Axial myopia cutting of the contact lenses bound to the convex surface by inserting the upper end of the cut convex mold into the jig of the toric lathe; The method of manufacturing a contact lens is characterized in that the step of: polishing the convex surface of the contact lens is completed myopia and then separating the contact lens from the convex mold to complete.

As such, in order to manufacture a contact lens, a mold in which synthetic resin is injected as a raw material is required, and as an embodiment of an injection apparatus and a mold configuration therefor for manufacturing a mold, the Republic of Korea Utility Model Registration No. 20-0347020 has a staircase at the bottom outside. An upper core having a first stepped portion formed therein and a coupling groove formed therein so that the lower portion of the upper core is inserted into one side to form a mold cavity at a predetermined interval, and the lower stepped second stepped step formed in the coupling groove. A mold of a contact lens for forming a mold mold by injecting a liquid mold material into the mold cavity to form a core and a lens core inserted into the other side of the coupling groove to form a mold cavity at a predetermined interval with a lower end of the upper core. In the mold injection molding apparatus, the lens core is formed with a curved portion so that the lens contact surface of the mold mold is convexly formed thereon, the curved An upper body having an inclined surface formed such that an inclined protrusion is formed at a peripheral portion of the lens contact surface at a periphery of the negative portion, and having a cylindrical shape perpendicular to a downward direction from one point of the inclined surface; The mold injection molding apparatus of the contact lens is known, characterized in that the lower body of the upper body is processed into a cylindrical shape having a larger diameter than the upper body is composed of a lower body protruding the engaging portion caught on the locking jaw in the coupling groove. have.

The conventional mold injection molding apparatus has a delay in productivity as the mold is molded into individual grains, resulting in decreased productivity, increased production cost by providing a cause of power consumption due to repeated press operations, and a process in manufacturing contact lenses. There was a problem that the overall work process is delayed because the supply of the mold is delayed.

Therefore, recently, in injection molding of a mold, a method of cutting and supplying individual molds after molding a mold itself by injecting a mold material into a mold provided so that several molds are connected at a time is used.
