摘要： A mechanism (10) for applying a clamping force to a columnar member (20), such as a tiebar, is described. The clamping mechanism includes a compressible member (22) surrounding the columnar member (20) for gripping the columnar member and transmitting a clamping force thereto, which compressible member is slidable along the columnar member. The mechanism further includes a clamping piston (40) for applying a clamping force, which clamping piston (40) has a bore (44) with an engaging surface (46) for receiving and frictionally engaging the compressible member (22). The frictional engagement between the compressible member (22) and the engaging surface (46) prevents any relative sliding movement between the compressible member and the clamping piston. The mechanism still further includes a sliding piston (50) for applying a clamping force and for causing the compressible member (22) to slide along the columnar member from an initial position to a preload position where the compressible member (22) is compressed by contact with the engaging surface (46) as the compressible member moves between the positions. Compression of the compressible member causes it to grip the columnar member and apply an initial clamping force. The main clamping force is applied to the compressible member and hence to the tiebar by moving the clamping piston (40) to a clamping position. A method for applying a clamping force to a mold using the clamp mechanism of the present invention is also described.

摘要： A mold press (10) includes an upper mold carrier (12) mounted to slide up and down along an upright mold press frame (14) and to rotate about a horizontal rotation axis (23). The mold press frame (14) is supported on a mold press base (18) to tip forward and aft about a horizontal upper mold pivot axis (20) disposed parallel to and below the rotation axis (23). A lower mold carrier (16) is supported on the mold press base (18) below the upper mold carrier (12) and above the upper mold pivot axis (20). The lower mold carrier (16) includes an lower mold mounting plate (62) that is pivotally supported on the mold press base (18) for tipping motion along a hinged edge about a lower mold pivot axis (68) that lies parallel to and below the rotation axis (23) and above the upper mold pivot axis (20). An electronic, motion controller may be programmed to coordinate the reciprocating, tipping and rotating motions to accomodate a variety of mold/retainer configurations. The motion controller may also be programmed to move the upper mold carrier (12) and an attached upper mold portion into ergonomically optimum positions that meet different operators needs.

摘要： A threaded actuator is disclosed for positioning a core (5) in a molding apparatus (1). The threaded actuator includes a hydraulic cylinder unit (11) having a piston rod (20) connected to the core (5) for positioning thereof. The core is subjected to intense force during the molding process and this force is transmitted onto the piston rod (20) and hydraulic cylinder unit (11) and its support. The hydraulic cylinder (14) has a threaded nose (15) which is secured within a threaded opening (30) in a support (12). A rotatable threaded connecting member (31) is threaded between the threaded nose (15) and the threaded opening (30) of the support structure. The outer (32,33) and inner (34,35) threaded connections of the rotatable threaded connecting member (31) are of different thread configurations to form a differential thread assembly. The configurations may differ either in pitch and/or in the handedness of the threads. The differential threaded assembly provides for relative positioning of the hydraulic cylinder unit (11) and core relative to the mold. A preload system includes a wall on the cylinder and a wall on the rod for preloading of the locked rod and the supporting components. The hydraulic cylinder and the piston rod are formed with stop wall members which provide for controlled extension of the piston rod for preloading of the piston rod and the supporting structure. A locking unit (22-28) provides for locking of the rod (20) in an extended position.

摘要： Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zum Schließen des Werkzeugs einer Kunststoffverarbeitungsmaschine, insbesondere einer Blasformmaschine, mit einem zweiteiligen Werkzeug (1, 2), das von zwei Werkzeugaufspannplatten (3, 4) getragen wird, mindestens einem Fahrantrieb (5), mindestens zwei Schließantrieben (8), wobei die Schließantriebe (8) jeweils aus einem hydraulischen Kolben-Zylinder-System mit einem Zylinder (9), einem Kolben (10) und einer Kolbenstange (11) bestehen und am Zylinder (9) ein Zufluß (14) und ein Abfluß (15) für Hydrauliköl vorgesehen ist, wobei die Kolbenstange (11) an ihrem Ende ein Riegelelement (12) trägt, das mit einem Gegenstück (13) zusammenwirkt, und wobei die Verriegelung der Kolbenstange (11) mit dem Gegenstück (13) zwecks Aufbringung der Schließkraft erst dann erfolgt, wenn sich das Werkzeug (1, 2) nahe an seiner Geschlossen-Position befindet. Erfindungsgemäß ist vorgesehen, daß alle Schließantriebe (8) zum Schließen des Werkzeugs (1, 2) mit großer Kraft von einer gemeinsamen Steuerung oder Regelung angesteuert werden, wobei keine Synchronisationseinrichtung zwischen den einzelnen Schließantrieben (8) vorgesehen ist und wobei die gesamte Schließbewegung des Werkzeugs (1, 2) in kontinuierlicher Weise und ohne Unterbrechung des Schließvorgangs erfolgt. Dadurch wird bei einfacher und preiswerter Ausgestaltung eine ökonomischere Betriebsweise möglich.
