FORMMASCHINE MIT SCHMIERMECHANISMUS UND VERFAHREN ZUR SCHMIERUNG DER FORMMASCHINE

摘要

A molding machine having a lubrication mechanism according to the present invention can effectively rubricate a ball screw and elongate a service life of the ball screw. In a clamping apparatus of an electric injection molding machine, a rotational movement of a rotational shaft of a motor (19) is converted into a linear movement in an axial direction by a ball screw mechanism (31). Atomized lubrication oil is directly sprayed inside the ball screw nut (25) from a spray nozzle (35). The lubrication oil, which has been sprayed from the spray nozzle (35), is recovered and reused.
