摘要： Bei einer Entnahmeeinrichtung zur Entnahme von Spritzteilen aus einer Kunststoff-Spritzgießmaschine sind an einem Gestell (20) ein erster Schlitten (S1) über einen ersten Antrieb (A1) und ein zweiter Schlitten (S2) über einen zweiten Antrieb (A2) im wesentlichen horizontal beweglich. Am zweiten Schlitten (S2) ist ferner ein dritter Schlitten (S3) in einer dritten Bewegungsrichtung beweglich, um ein Entnahmeelement in die geöffnete Spritzgießform (15) einfahrbar zu gestalten. Dadurch, dass am zweiten Schlitten (S2) ein Schwenkantrieb (A4) zum Schwenken des dritten Schlittens (S3) aus der dritten Bewegungsrichtung in eine durch das Zusammenspiel der Antriebe und des Schwenkantriebs überlagerten vierten Bewegungsrichtung vorgesehen ist, wird eine Entnahmeinrichtung geschaffen, die auch bei beengten Raumverhältnissen in Verbindung mit größeren Maschinen betrieben werden kann (Fig. 1).

摘要： The invention relates to a drive unit for a machine, especially an injection press. Said drive unit comprises several linear motors (L1, L2) parallel to each other in a common advance direction (a-a), said motors having equally acting members which are mutually connected for common motion. Said linear motors (L1, L2) comprise magnetic elements (23, 24) in the advance direction as well as coil elements (26, 27) co-operating with the magnetic elements. According to the invention, force determination means (40) for determining the path-dependent force of the linear motors (L1, L2) are installed at least during assembly or initial operation and a controller (41) is used during operation for setting the power delivered to the linear motors (L1, L2) by the power part to a desired characteristic on the basis of the force depending from the linear motor position determined by the force determination means, whereby a smooth force characteristic can be obtained.

摘要： According to the invention, the U-shaped profile rail for constructing a handling device for an injection molding machine is provided in the form of cavities. The cavities (10b) and, according to requirements, recesses (10c) situated on the surface are arranged in such a way that at least extremities (10d) of the limbs (10a) can elastically move toward or away from one another. The profile offers fastening possibilities for guides of the handling device. The guides can be fastened to the extremities (10d) of the limbs (10a), whereby the extremities (10d) can elastically move in relation to the limbs (10a). As a result, the profile rail is designed such that it is as elastic as possible for receiving guides, however, it can also be designed to be as stiff as necessary according to requirements.

摘要： The invention relates to an injection molding machine that is provided with a protective cover (15) that can be displaced from a non-protective to a protective position by means of a handle (27) and that is used to cover the injection molding nozzle during the injection process. Said protective cover is axially configured in a substantially parallel position with respect to the axis of injection (s-s) and can be displaced to a protective position. The protective cover (15) comprises a lower part (15a) on which an upper part (15b) is mounted so as to be swiveled about a substantially parallel swivel axis (a-a) with respect to the axis of injection (s-s). Said lower part (15a) and said upper part (15b) can be displaced together to a non-protective and to a protective position, thereby combining a reliable support of the protective cover with a good accessibility of the nozzle and the plastification cylinder.

摘要： The invention relates to an injection moulding machine provided with a multi-piece machine base comprising at least two adjacently positioned components (10a, 10b). The stationary mould support (12) can be fixed to the component (10b) of the machine base. The aim of the invention is to easily assemble the machine base which meets the demands occurring during operation of the injection moulding machine. To this end, the components (10a, 10b) of the machine base (10) underneath and in the vertical projection of at least the base (12a) pertaining to the stationary mould support (12) can be connected thereto independently from each other.

摘要： The invention relates to an injection molding machine in which the injection molding unit (S) and the mold-closing unit are at least partially operated by electrical drive units in the form of a linear motor. The rotor and the stator of said linear motor have cylindrical lateral surfaces (11, 12), these cylindrical lateral surfaces of the stator and the rotor being arranged concentrically and the stator windings being essentially symmetrical to the a-a axis of motion of the linear motor. According to the invention, several equally acting first lateral surfaces (11) are interleaved with a corresponding number of equally acting other lateral surfaces (12) and the first and/or other lateral surfaces can be operated together, respectively, so that they cooperate. This results in a linear motor which is able to provide the advance forces that are required for injection molding machines.

摘要： A method for evaluating good or bad moulded parts that are produced in an injection moulding machine. The parameter curves of a first parameter (y) are detected as a function of a second parameter (x) during a plurality of moulding processes and the mean is taken to form a mean curve (M2). A standard deviation is calculated on the basis of the detected parameter values in order to enable adjustment of a permitted range in which the parameter curves during production should lie when the moulding parts are manufactured, so that the respective moulding parts can be evaluated as good. The standard deviation is calculated according to the second parameter (x). This enables calculation of a permissible variation in order to provide a suitable tolerance band even when there are heavy fluctuations of the parameter that is to be monitored, whereby the rejection rate can be reduced even further.

摘要： The invention concerns an injection-moulding machine for processing plasticizable compounds, wherein a structural unit comprising at least the movable mould carrier (11), the stationary mould carrier (12) and the closure arrangement (13) of the mould-closure unit is supported on support elements (15) on the machine base. A pivot pin, about which the structural unit can be pivoted, extends transversely to the closure axis (s-s). Provided as the means for pivoting and displacing the structural unit is a drive unit (A) which is connected in articulated manner to the machine base (10) and to the structural unit at articulation point (21) which is at a spacing from the pivot pin (18). When the structural unit is moved from the horizontal position into the vertical position the drive unit (A) first pivots the structural unit and then also displaces it.

摘要： The injection-moulding unit proposed has a support block (10) and an injection bridge (25) which can be moved towards and away from the support block (10) in order to cause conveyor means (72) to move relative to a receptacle (17). This injection motion is produced by a motor (51) driving several spindle drives (E). The injection bridge (25) has a recess or aperture in which the motor (51) comes to rest.

摘要： Bei einer Vorrichtung zur drehsicheren Festlegung eines Kugelrollspindelmechanismus (10) zur Erzeugung einer linearen Bewegung einer ersten Baugruppe bis zur Anlage einer weiteren Baugruppe, bestehend aus einer Kugelrollspindel (16) und einer Mutter (14), sind Blockiermittel (17) vorgesehen, die bei Anlage der beiden Baugruppen das rotierende Teil des Kugelrollspindelmechanismus infolge einer durch eine äußere Kraft hervorgerufenen Reaktionskraft und Überwindung der Kraft von Rückstellmitteln (18) gegen Drehung gesichert festlegen. Dadurch, daß bei Anlage die Blockiermittel (17) von der ersten Baugruppe beabstandet sind und bei Auftreten der äußeren Kraft über die Antriebseinrichtung (15) das drehbare Teil so lange gegen Drehen gesichert gehalten ist, bis der Abstand b zwischen der ersten Baugruppe und dem Blockiermittel (17) aufgehoben ist, wird günstig die Lebensdauer und Verschleißfreiheit der Vorrichtung erhöht.
