    专利说明:

    The invention relates to a molding machine with at least one supporting, at least one cavity having structural element and a container for a pressure medium or a vacuum. In addition, the invention relates to a shaping system with at least one such shaping machine and a pressure medium or vacuum source.
    In molding machines, in particular compression molding or injection molding machines, in some customer applications, such as ejectors or blow-out devices, a lot of compressed air is needed for a short time. In many cases, the supply size of a central pressure medium source is insufficient. In addition, there is often insufficient short-term amount of air at the forming machine. In these cases, a container for a pressure medium (for example, a compressed air tank) is installed in or on the machine, which serves as a balance memory for the actual pressure medium source. Similar designs are also available for vacuum systems. In order to be vacuumed quickly, you need a sufficient vacuum reservoir or a correspondingly generously dimensioned vacuum pump. Such generous vacuum pumps or similarly sized pressure medium sources are relatively expensive. But also compressed air tank or vacuum tank for temporary storage are very bulky due to the usually cylindrical cubature in the molding machine and thus disturbing.
    The object of the present invention is therefore to provide a comparison with the prior art improved molding machine. In particular, the disadvantages mentioned should be eliminated.
    This object is achieved by a shaping machine having the features of claim 1. Accordingly, the invention provides that the container is formed by the supporting structural element and the cavity or the container is arranged in the cavity of the structural element. The idea is to be seen in the fact that existing or specially made hollow body in structural elements of
    Forming machine can be used as a container (pressure medium storage or vacuum storage).
    As preferred concrete embodiments, it is provided that a profile-shaped frame member, a forming tube, a mold clamping plate and / or a face plate form the supporting structural element / forms. For example, Thus, the frame of the molding machine is designed with hollow profiles and you can seal these hollow sections at the end faces and use directly as a compressed air tank or vacuum tank. Likewise, the cast plates (mold platens or face plates) with cavities could be used as storage.
    In order to be able to dispense with sealing welding of the structural elements, it is preferably provided in one exemplary embodiment that the container arranged in the cavity is designed as a hose. It is thus possible to insert large hoses into existing cavities, such as molding tubes, for example, and to use these as storage or containers for a pressure medium or a vacuum. This also offers the advantage that no separate rust protection is required.
    The shaping machine preferably has a drive device which can be acted upon by the pressure medium or the vacuum. For example, For example, such a drive device may be an ejector device or a blow-out device or a similar drive of the forming machine. In order to achieve a suitable and suitable pressure medium or vacuum transmission is further preferably provided that the drive device is connected via a consumer line to the container for the pressure medium or the vacuum.
    Furthermore, it is preferably provided that the container with at least one access device can be opened and closed. For this purpose, it may additionally be provided that the access device has at least one, preferably switchable, valve.
    Protection is also desired for a molding machine with at least one molding machine according to the invention and a printing medium or
    Vacuum source. In this case, this pressure medium or vacuum source is preferably designed either as a compressor system for compressed air or as a vacuum pump. For the supply of the individual existing in the molding machine container with a pressure medium or a vacuum is preferably provided that the pressure medium or vacuum source via a machine line (and an access device) is connected to the container for the pressure medium or the vacuum.
    Further details and advantages of the present invention will be explained in more detail below with reference to the description of the figures with reference to the exemplary embodiments illustrated in the drawings. Show:
    Fig. 1 shows schematically a molding machine with a molding machine and a pressure medium or vacuum source and Fig. 2 in a 3D view of the frame of a molding machine.
    In Fig. 1, a shaping system 11 with a shaping machine 1, in particular an injection molding machine, and a pressure medium or vacuum source 12 is shown schematically. On the left side, this shaping machine 1 has a known injection unit 14 and on the right side a known closing unit 15. The injection unit 14 is mounted on a structural element 2, which has a Flohlraum Fl. This structural element 2 together with the Flohlraum Fl forms a container 3 for a pressure medium M or vacuum V.
    The entire shaping machine 1 has in the frame 19, in addition to the carriers 20, a plurality of profile-shaped frame members 4. These profiled frame members 4 form a supporting structural element 2 with at least one Flohlraum H. The upper of these cavities H forms together with the structural element 2 directly a container 3 for a pressure medium M or a vacuum V. The lower formed in the structural element 2 Flohlraum H forms indirectly, the receptacle for a container 3 for a pressure medium or a vacuum V, said container 3 is formed as a hose.
    The closing unit 15 has, inter alia, the spars 17, the movable platen 5 (with a schematically illustrated ejector plate 24), the fixed platen 6, the mold halves 21 and 22 mounted on the platen 5 and 6 and the cavity 16 and the face plate 23. In these formed as cast plates plates 5, 6 and / or 23 -which support structural elements form 2 - (container-free) cavities H are formed or provided, whereby these supporting structural elements 2 and their cavities H turn directly form container 3. For the supply of the drive device 8 with pressure medium M or vacuum V two different embodiments are possible, in both variants, a pressure medium or vacuum source 12 (for example, a compressor unit or a vacuum pump) is provided.
    In the first embodiment, first a direct machine line 13 runs from the pressure medium or vacuum source 12 to the container 3. Via the access device 10 the pressure medium M or the vacuum V reaches the container 3 (shown at the bottom). and closable access device 10 is provided, starting from which a consumer line 9 from the container 3 extends directly to the drive device 8.
    In order to require less line length and to facilitate the control, especially in many existing containers 3, a distributor 18 is provided according to a second embodiment. From the pressure medium or vacuum source 12, a first machine line 13a extends to the distributor 18. From this distributor 18 run several, in the specific case five, second machine lines 13b to the access devices 10 of the individual containers 3. The same second machine lines 13b then serve as first consumer lines 9a, to supply the stored pressure medium M or the vacuum V back to the distributor 18 if necessary. From this distributor 18, the drive device 8 is then directly supplied with the pressure medium M or the vacuum V via the second consumer line 9b. Depending on requirements, the pressure medium M or the vacuum V can be connected via the distributor 18 via the respective first consumer lines 9a. In this second embodiment, only one access device 10 and only one line is thus provided per container 3, which simultaneously forms the second machine line 13b and the first load line 9a.
    FIG. 2 shows the frame 19 of a shaping machine 1 in a 3D view. In this case, the profile-shaped frame members 4 are particularly well recognizable, which form the bearing, provided with at least one Flohlraum Fl structural elements 2. In addition, in the frontal region of these profile-shaped frame members 4, the access device 10 co-forming openings are shown and recognizable.
    The present invention thus offers the advantage that the containers 3 for a pressure medium M or a vacuum V are already integrated in cavities H present in structural elements 2 of the shaping machine 1. Thus, these structural elements 2 offer a dual function in that on the one hand they form a load-bearing component and on the other hand they directly form or indirectly receive a container 3.
