    The present invention relates to a closing unit for an injection molding machine having the features of the preamble of claim 1,
    It is known in the art to sink drives for moving parts of an injection mold in a mold mounting plate. In particular, the rotational movements of index plates are produced by default in the movable platen immersed electric or hydraulic drives. The reason for this is that by sinking the drive is to be prevented that the stroke of the machine is reduced by the arrangement of the drive.
    It is known to use a hollow shaft motor as a drive, which is pierced by a shaft which serves to rotate an index plate (DE 10145461 A1).
    However, the Einiasseri of the drive in the platen this is structurally weakened and enormously important especially in Prizisionsspritzgießen dimensional stability of the platen is reduced. In addition, an extremely difficult thermal situation is to be expected especially for electric motors, which are embedded in a platen, since the mold clamping plate surrounding the drive naturally prevents the dissipation of heat. It is therefore not possible in all applications to engage the drive in the platen.
    The object of the invention is to provide a closing unit which houses a drive for the rotation of a movable tool part in such a way that the expansion of the closing unit in the closing direction can be kept small.
    This object is achieved by a closing unit with the Mefkrnalen of claim 1
    Since the drives used for the rotation of index plates and the like, usually along their drive axis have a greater extent than P.006 / 016 27/03/2013 11:20 No: R462 2/15 27/03/2013 11th : 10 + 43-512-583408 TÜRG6LER & HQFINGER p. 07/16 27/03/2013 11:10 + 43-512-583408 TÜRG6LER & HQFINGER p. 07/16 ·· ·· ·· ··· ♦ * · ···· · · · · · · · - · · • i $:: ·, · «· · · · · · · · · · · · · · ·· ·· ··· 2 across the drive axis, the overall length of a horizontally closing unit can be made as short as possible or analogous to the overall height of a vertical clamping unit.
    Preferred embodiments of the invention are defined in the dependent claims.
    Preferably provided is an embodiment in which a drive axle in an end view of the clamping unit encloses an angle between 45 degrees and 135 degrees, preferably an angle between 80 degrees and 100 degrees and particularly preferably an angle of substantially 90 degrees, with the locking axis.
    It is particularly preferred that the drive is arranged on a side of the platen facing away from the tool part, whereby a better accessibility of the drive and its components (eg position measuring system) can be achieved. It is then also possible to allow the drive together with other components so that it can be easily and quickly assembled and disassembled, for example, if the clamping unit is not to be operated constantly with a Indexplattenwerkzeug.
    Preferred is an embodiment in which the movable or rotatable tool part is formed as an index plate.
    In order to leave space for an injection device on a fixed platen, it can be provided that the platen is a movable platen, preferably along a closing axis,
    In particular, when the drive is arranged on a movable platen, it may be advantageous if the drive is attached to the platen, as this automatically a coupling of the movement of the tool in the direction of a Sehtießachse is made. P. 0077016 27/03/2013 11:20 No .: R462 3/15 27/03/2013 11:10 + 43-512-583408 TORGGLER & HOFINGER P. 08/18 ·, ·: · · · · · · · · · ·: · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · '· · · · · ·
    It may further be provided that the drive is designed as an electric drive, preferably as a servo drive. Such motors are capable of providing services that are significantly above their rated power over short times. Since movable tool plates, in particular index plates, also rest during the majority of an injection molding cycle (with respect to the movable platen), this makes the drive correspondingly small and consequently cost-effective.
    The movement generated by the drive can be transmitted to the rotatable tool part in a particularly simple manner by providing a shaft displaceable along a closing axis for rotating the tool part, which preferably passes through the mold clamping plate.
    In order to enable a movement of the shaft (preferably together with the movable tool part) along a closing axis, a hollow shaft rotatably coupled in a rotationally locking manner to the shaft can be provided, the position of which is fixed along the closing axis with respect to the platen.
    A particularly simple transmission of the movement of the drive to the hollow shaft can be achieved by a driven by the drive pinion is provided, which cooperates for rotation of the hollow shaft with a toothing on the hollow shaft.
    In particular, when, as described above, an electric motor or a servomotor, which is briefly loaded significantly above the rated power, is used, the transmission ratio between pinion and teeth on the hollow shaft between 1: 1 and 10: 1, preferably between 2: 1 and 5: 1 and more preferably 4: 1 (speed ratios). The high speeds, which are achieved by the drive, can be adapted in this way, for example, the index plates targeted rotational speeds.
    Complete elimination of weakening of a platen can be achieved by reducing the time required to transmit the rotational movements to the P.008 / 016 27/03/2013 11:21 No: R462 4/15 27/03/2013 11:10 +43 -512-583408 TORGGLER & HCFINGER S: 09/16 27/03/2013 11:10 + 43-512-583408 TORGGLER & HCFINGER S: 09/16: ··· · · '' ··: · · " Rotatable tool part is slidable over an already existing, preferably hydraulic or electrical Auswerfervorrichturtg along the closing axis.
    Preferably, an angle drive is provided on the drive, whereby a simple transmission of the drive movement in the direction of the locking axis can be realized

    FIG. 1 shows an inventive, horizontally closing closing unit 1. It has a platen 3 movable along a horizontal closing axis X. In this embodiment, the rotatable tool part 4 is an index plate which is rotatable about the shaft 5 and displaceable along the closing axis X. The electric drive 2 in this case is arranged on the side facing away from the movable tool part 4 of the movable platen 3. Shown is also the drive axis Y of the drive 2, which include 90 degrees in this embodiment. However, the exact number of degrees is not essential to the invention.
    The movable platen 3, the rotatable tool part 4 and the drive 2 can also be seen in Figure 2 in sectional view. It is further shown a shaft 5 which is movable by an ejector 9 along the closing axis X. In addition, a hollow shaft 6 can be seen, which is rotatably coupled with the shaft 5 rotationally. A pinion 7 is engaged with the toothing 8 of the hollow shaft 6. The Ritzet 7 is driven by the drive 2. Between the pinion 7 and drive 2 is an angle drive 12, 27/03/2013 11:21

    Furthermore, in Figure 2, a mounted tool 13 can be seen, in which the index plate is retractable.
    FIG. 3 shows a vertically closing clamping unit according to the invention. Here too there is an index plate, which is analogous to that of FIG. 1, apart from the fact that the locking axis X runs vertically here. In this exemplary embodiment too, the electric drive 2 is arranged on the side of the movable mold mounting mat 3 which faces away from the movable tool part 4.
    The present invention is not limited to the embodiments shown here. For example, the locking axis (X) does not have to coincide with an axis of an ejector (11).
