<p>The precision injection molding (1) device comprises parts constituting footprint models to be molded along a central axis (2) in the periphery, and a central connecting unit constituting the central axis to which the parts are connected constituting the models of imprint to be molded. The set is qualified by a casting tree. The central connecting unit comprises an interlocking rod (4) for fixing parts constituting models of impression over its entire periphery, and a flared base (6) with a connecting unit (7). A unit is arranged for holding the connecting unit in a vertical position. The precision injection molding (1) device comprises parts constituting footprint models to be molded along a central axis (2) in the periphery, and a central connecting unit constituting the central axis to which the parts are connected constituting the models of imprint to be molded. The set is qualified by a casting tree. The central connecting unit comprises an interlocking rod (4) for fixing parts constituting models of impression over its entire periphery, and a flared base (6) with a connecting unit (7). A unit is arranged for holding the connecting unit in a vertical position, and comprises a flat base at its center of a removable fastener adapted to the connecting unit of the flared base. A unit is arranged for handling the central connecting unit, and comprises a removable unit connected to the connection unit of the flared base. The interlocking unit comprises holes drilled around the periphery of the central connecting unit according to a distribution unit optimized and adapted to the size and shape of the parts constituting the models of imprint to be molded. The connecting unit is a threaded flare. The central connecting unit is conical, and the acute angle formed with flared base is rounded. An independent claim is included for a process for precision injection molding in a hollow matrix by lost-wax.</p> |
