Abstract:
1. An ejector comprised of: a frame, which holds a plurality of mold parts, each mold part being used for molding a work piece, the mold parts having cavities in which work pieces are molded, each mold part having a top and a bottom and being attached to and rotating with an axle having a center axis about which each axle and each corresponding mold part rotates within the frame, the mold parts being arranged so that that cavities of the mold parts face away from the axle; an ejector mechanism coupled to the frame and located substantially between the axle and at least one of the plurality of mold parts, the ejector mechanism being comprised of first and second ejection arms, which are sized, shaped and arranged to move transversely relative to the axis of the axle, a rotation of the mold parts around the axle by ninety degrees positions a first mold part in a first position whereat a work piece in said first mold part can be ejected after a second mold part is closed to form a second work piece in said second mold part, whereat transverse motion of the ejection arms toward the first mold part causes the first work piece in the first mold part to be ejected from the first mold part's cavity, said first and second ejection arms acting at the top and bottom of the second mold part; and wherein a second work piece to be molded in a second mold part is ejected from the second mold part after the first work piece is ejected from the first mold part; and wherein subsequent rotations of the mold parts by ninety degree increments about the axis locates one of them into said first position and another of them into said second position.
