A vent for a mold for producing foamed articles is described. The mold comprises an upper mold and a lower mold releaseably engageable in a closed position to define a mold cavity. The vent comprises a housing which is engageable to the mold, a passageway and an obstruction disposed in the passageway. The passageway and the obstruction are slidably movable in a first direction with respect to one another and define an opening between an interior and an exterior of the housing. The obstruction has a varying diameter in a direction parallel to the first direction. The subject mold and method are particularly well suited for the production of molded foam (e.g., polyurethane) articles.
