Abstract: An injection mold is configured to form an eyeball for a fishing lure. The injection mold includes a first mold plate, a first stem plate, a second stem plate, and a second mold plate. The first mold plate defines a first injection port. The first and second stem plates and the second stem plate each define a plurality of stem cavities. The second mold plate includes first and second sides and a second injection port extending between the first side and the second side. The second side defines an iris cavity in fluid communication with the second injection port. The injection mold is configured to be assembled in a first configuration, to receive a first flowable material to form a pupil stem of an eyeball, and a second configuration, to receive a second flowable material to form an iris of the eyeball.
