    The invention generally relates to a locking device for locking an end plate or a platen on at least two, differently positioned bars of an injection molding machine with at least two clamping elements, each associated with one of the differently positioned spars and each having at least two half shells.
    The invention thus relates to a Verriegetungsvorrichtung that allows the clamping or holding of Stim plates (or a clamping plate) to Holmen an injection molding machine. For this purpose, various locking devices have been known for many years.
    For example, JP 29 89 116 shows a locking device with a hydraulically driven lifting cylinder, which translates the half-shells of two clamping elements.
    In a very similar manner, the synchronization of the individual clamping elements of the locking device takes place in EP 1 238 777 B1. But the individual shells are connected by means of a rotating mechanism. The translational drive takes place only on a single half shell and is forwarded by appropriate rods or rotary joints on the other half shells.
    From AT 003 639 U1 locking devices emerge in which half-shells different clamping elements are pushed apart by a hydraulic drive device or pulled together. This drive unit is not in direct contact with a rocker synchronizing the movement of the upper and lower clamping elements. Rather, the rocker is rotatably mounted on a bearing pin, said bearing pin is fixed to the movable platen in combination. The connection between an upper and lower Haibschale thus takes place only and directly via a retractable and extendable piston rod.
    Furthermore, JP 39 27 066 shows a locking device for synchronizing all four clamping elements, again using a hydraulically retractable and extendable piston rod is used. 69221 22 / sk 2
    In contrast to the previously cited documents, the invention relates in particular to a locking device for locking an end plate or a platen on at least two differently positioned bars of an injection molding machine with at least two clamping elements, each associated with one of the differently positioned bars and each having at least two half shells , wherein at least two half-shells, which are assigned to different clamping elements, each articulated via a rod with a common synchronization element and wherein both rods are connected on the one hand to the respective half-shell and on the other hand to the common synchronization element via swivel joints
    Such, the preamble of the present invention forming, locking device is, for example, in JP 61 54 989, where two rods are pivotable by the translational movement of a piston, so that the half shells of two different clamping elements are moved away from each other or moved to each other. The disadvantage here is that the drive unit for the piston is relatively far away from the locking device. In addition, a translational retraction after reaching the maximum position or the dead center is associated with a relatively large amount of force.
    The same applies to the likewise forming the preamble of the present invention EP 2 163 370 A1, wherein the synchronization element is also moved laterally and translationally, this movement is transmitted via laterally engaging rods and corresponding hinges to the Hatbschaien different clamping elements. In particular, the synchronization element for the synchronization movement requires a relatively large amount of space, since it always needs the space for the stroke to be performed.
    The object of the present invention is therefore to provide a comparison with the prior art alternative and simplified locking device.
    This is achieved for a locking device with the features of the preamble of claim 1, characterized in that the synchronization element is rotatable. As a result, the synchronization element does not have to perform a stroke and therefore does not require any additional space for the synchronization movement. By this design also a much better power transmission from the synchronization element is given to the pivotally connected rods and thus further on the half shells. In particular, the dead center can be overcome much easier. · «I · ** 3
    According to a preferred embodiment of the present invention can be provided that the synchronization element is rotatably driven by an electric motor. Preferably, the electric motor in the form of a three-phase asynchronous motor is formed with a transmission such engine can continue even beyond the dead center without problems without the deadlock was solved immediately. Alternatively, the synchronization element can also be driven by a hydraulic motor.
    Preferably, it may further be provided that the rods engage in relation to the synchronization element with respect to the axis of rotation of the synchronization element. As a result of this counteracting engagement of the rods on the synchronization element, the force transmission into both rods takes place uniformly and thus has no negative effects on the torque.
    Furthermore, it can be provided that the half-shells of a clamping element are each translatable to each other, wherein the movement of the clamping elements is synchronized by a synchronization link with respect to dte movable platen, wherein the synchronization linkage comprises at least two gegengleichgleich - preferably four pairs in pairs - moving connecting rods
    In addition, it can preferably be provided that the individual, differently positioned spars are of essentially identical construction. The same applies to the clamping elements and the Hatbschalen, but which may be partially mirror images of each other, but otherwise have substantially identical dimensions.
    Furthermore, protection is desired for an injection molding device with a fixed platen, a movable platen, optionally a front plate, the movable platen and the end plate passing spars and a locking device according to one of claims 1 to 5 for locking the optional end plate or the movable platen to the Holmen. Depending on whether the injection molding machine is designed as a two-plate machine or as a three-plate machine, the locking device can be attached to the movable platen or to the front plate. ♦ · ···· * · * · * · ♦ 4
    Further details and advantages of the present invention will be explained in more detail below with reference to the figure description with reference to the dargesteliten in the drawings embodiments. Show:

    Fig. 6 is a section through two synchronized locking devices.
    Fig. 1 shows a general view of an injection molding machine 50 with clamped between the stationary platen 20 and the movable platen 19 mold halves 24. Between the movable platen 19 and the end plate 2, a toggle mechanism 21 is arranged The movable platen 19 and the face plate 2 are each about Sliding shoes 38 slidably mounted on a guide rail 23 of a frame 22 of the injection molding machine 50 All three plates 2,19 and 20 are penetrated by a total of four bars 3, wherein at the stimplattenseitigen end of the bars 3, a locking device 1 is shown schematically. This locking device 1 is mounted on the end plate 2 and holds by clamping the half-shells 7 and 6 or 8 and 9 of the clamping elements 4 and 5, the end plate 2 to the bars 3 fixed. In order to enable the synchronization of two clamping elements 4 and 5, on the one hand in itself already known rods 16 and 15 (and the connecting rods 17 and 18 not shown here) and on the other hand connected via rods 10 and 11 with the half shells 6 and 8 synchronization element 12th The synchronization element 12 is rotatably driven by an electric motor 14, wherein the synchronization element 12 rotates about the axis of rotation D.
    2, two mutually separate locking devices 1 and 1 'are arranged on the front plate 2. The components of both locking devices 1 and 1 'are substantially identical and are therefore denoted by the same reference numerals. 2, the locking device 1 on the right side in the closed position, while the locking device 1 'is shown in the open position on the left side. • * · «· t ·« ·· < * * * · · · * * * «* ♦ · · β · · * · * ···· * 5
    Such a locking device 1 consists of two different spars 3 associated clamping elements 4 and 5, each having two half-shells 6, 7 and 8, 9 with inner holding grooves 28. About this holding grooves 28, the clamping elements 4 and 5 engage the spars 3. The half shells 6 and 9 are connected via known, diagonally opposite connecting rods 17 and 16, while the half shells 7 and 8 are connected via the diagonally opposite connecting rods 15 and 18. But to get the general translational movement in the individual, each inner half shells 6 and 8, these are connected via rods 10 and 11 with a synchronization element 12. The rods 10 and 11 are each pivotally connected via pivot joints 13 on the one hand with the synchronization element 12 and on the other hand with the respective half-shell 6 and 8 respectively. This synchronization element 12 can be driven via the electric motor 14 so as to be rotatable about the axis of rotation D. The motor 14 is connected via a motor flange 27 and studs 25 with a mounted on the face plate 2 stimplattenseitigen flange 26.
    3, a section through the two locking devices 1 and 1 'in the region of the synchronization element 12 is shown. The total of four studs 25 as well as the total of four pivots 13 can be seen. In this illustration, the two Extermpositionen the respective locking devices 1 and 1 'are shown. By the rotary drive of the synchronization element 12, in particular the dead center position shown on the right - in which the rods 10 and 11 are fully stretched - by simply turning to the left quickly and with even force through again overcome.
    In Fig. 4 to a matching view of the face plate 2 together with the two locking devices 1 and 1 'can be seen, in which case the
    Connecting rods 15 and 17 exactly overlap the connecting rods 16 and 18 for illustrative reasons.
    In the section according to FIG. 5, it can be seen that the two rods 10 and 11 are each pivotably connected to the synchronization element 12 via bolts 29. These bolts 29 can be held in the synchronization element 12 via securing screws 30, not shown here. In principle, the locking screw 30 may also be designed in the form of a small threaded pin. The synchronization element 12 itself is connected to a shaft mount 34 via a bearing 31 delimited by securing rings 35 and preferably pressed into the synchronization element 12, wherein these bearings are connected to a shaft mount 34
    Shaft mount 34 is fixedly mounted in the face plate via an Allen screw 33. The motor 14 itself is mounted on the end plate 2 via the motor flange 27 and the stud bolts 25 and the end flange 26. This electric motor 14 drives a stub shaft 32 which rotatably drives the rocker-shaped synchronization element 12 via a coupling part 36 (preferably a backlash-free shaft coupling, eg a ROTEX <&&> coupling).
    FIG. 6 also shows a possibility of how four clamping elements 4, 4 ', 5 and 5' can be synchronized via a single electric motor 14. In this case, the two synchronization elements 12 are connected via a transverse synchronization linkage 37 or 37 ', wherein in this representation according to FIG. 6 the two actually non-matching extreme positions are shown.
