Abstract
A mold 300 for making a member having at least one first section of a first material and at least one second section of a second material includes first and second plates or mold halves 332,334 adapted to cooperate with each other when positioned in opposing relationship along a mold-closing axis and reciprocally movable relative to one another along the axis during a molding cycle. The first and second plates or mold halves 332,334 define a member-forming area therein when the mold is in a closed position. Sprues in the first and second plates or mold halves are in communication with the portions of the first and second sections respectively of the member-forming area. An ejector 348 for ejecting an eventually mold member includes one surface defining a boundary of the member-forming area. The ejector is movably disposed in one of the plates and is movable into the member-forming area. The ejector 348 is positionable in a first position such that the first material is introduceable through the at least one first sprue 356 while another surface of the ejector blocks the at least one second sprue. The ejector 348 is then positioned in a second position within the member-forming area such that the second sprue is uncovered. The second material is introduced into the second portion 212 of the member-forming area through the at least one second sprue.
