Example Embodiment
[0084] Example one
[0085] Such as image 3 As shown, an intraocular lens forming mold includes a male mold 1 and a female mold 2. The male mold 1 is set above the female mold 2, and the middle area of the male mold 1 is an upwardly convex arc area. The center line is the center line of the first optical zone of the male mold 1; the middle area of the female mold 2 is an arc-shaped area recessed downward, and the center line of the arc-shaped area is the center line of the second optical zone of the female mold 2. A positioning boss 101 is provided on the bottom of the male mold 1 to rotate and extend in the circumferential direction, and the positioning boss 101 is located outside the first optical zone, such as Figure 5 As shown, the positioning boss 101 is an annular boss, the cross-sectional shape of the positioning boss 101 is a trapezoid, and the rotation axis of the positioning boss 101 is on the same straight line with the center line of the first optical zone. A po...
Example Embodiment
[0093] Example two
[0094] The difference between this embodiment and the first embodiment is:
[0095] The cross-sectional shape of the conduction port is circular. In other embodiments, the cross-sectional shape of the conducting opening may also be a parallelogram.
Example Embodiment
[0096] Example three
[0097] The difference between this embodiment and the first embodiment is:
[0098] In this embodiment, such as Figure 8 As shown, the cross-sectional shape of the positioning boss 101 and the positioning groove 201 is rectangular, and the protruding end of the positioning boss 101 is provided with a boss chamfer 6, and the cross-sectional shape of the positioning boss 101 is designed to be rectangular, and the positioning The protruding end of the boss 101 is provided with a boss chamfer 6, which can ensure that the positioning boss 101 is easily inserted into the positioning groove 201, and at the same time, it can reduce the manufacturing difficulty of the mold and simplify the manufacturing process, thereby reducing the manufacturing cost.
[0099] Of course, in other embodiments, the cross-sectional shape of the positioning boss and the positioning groove may also be a triangle. In addition to quick positioning, the triangular shape can also save material...
