In this paper a new method of automatic design for the layout and sizing of the ejector pins of the plastic injection mold, based on the discrete geometry of the plastic part, is presented. The proposed algorithm consists of a first phase of geometric analysis in which a node mesh corresponding to the surfaces to be molded by the lower mold cavity is generated. Then the variations of the difference...
