internal undercut
A feature on the interior of a part that will not allow a mold that contains it to slide away along the parting direction. An internal undercut can be either a protrusion or a depression (hole or pocket) and requires an additional mold piece to form its shape. Most internal undercuts require an internal core lifter. However, if the feature can be accessed through an open side of the part, a side-core can be used.
