Abstract
An injection-molding mold has a pair of mold parts each in turn having a generally annular outer edge and a generally annular inner edge directed in a closing direction. The mold parts fit together on closing in the direction with a workpiece between them and with the outer edges engaging each other and the inner edges engaging opposite faces of the workpiece. The inner edges form with the outer edges an annular compartment containing an outer periphery of the workpiece engaged between the inner edges and one of the mold parts is formed with a port opening into the compartment. In accordance with the invention a body forming at least part of one of the inner edges is movable on the respective mold part in the closing direction, and structure is provided for displacing the body in the closing direction away from the respective mold part for engagement with the workpiece on closing of the mold and for positioning the body in the direction relative to the respective mold part.
