Abstract

A transfer molding machine (10) with an injection mold plate (12). The injection mold plate has ejection pins (22,24) for ejecting a cull in a first direction (40). Each of the ejection pins (22,24) has a sprue abutment (50) with a notch (52). The notch is oriented to enable dislodging of the cull in a second direction (54), substantially normal to the first direction (40) and away from the sprue abutment (50). A method (100) for cull removal by transfer molding machine (10) upon curing a molding ends with the cull being moved out of the transfer molding machine (10) using a movable bar (200) with stubs (202).
