    专利说明:

    The invention refers to an extrusion device for manufacturing molded components, which comprises a conveyor container and a delivery device for supplying a material to be extruded to the conveyor container. In addition, the extrusion device comprises a forming extrusion port as the output of the conveyor container.
    Extrusion devices are conveyor devices, which eject masses of solids to viscous at a high pressure and a high temperature continuously from a forming opening in accordance with the functional principle of the helical conveyor. This method is called extrusion.
    From DE 2 004 888 B 1, a device for manufacturing plastic sheets is known. The device represents an extruder. The roller elements can be adjusted at the exlrusor outlet.
    The manufacture of components by extrusion is well known. In this context, molded components that are formed of the most varied materials, for example, plastic, metal, or glass, can be extruded. However, normally its complexity is limited with respect to the design of its shape to the respective limited embodiments of an extrusion device.
    In the case of very complex molded components, which can present the most varied designs in their three-dimensional geometry, in terms of their manufacture as an extruded component they are extremely dependent on the material and, in this sense, manufactured with limitations.
    Therefore, in particular for a ceramic material, it is only possible to manufacture components by common extrusion devices to a very limited extent, this being possible only for very simple straight geometries. This refers in particular to the so-called uniaxial components, so that manufacturing is restricted to them.
    Therefore, in the case of the usual ways of proceeding, it is also necessary that a plurality of the most varied extrusion devices be kept available in order to be able to create different geometries, even if they are very simple.
    The present invention solves the technical problem of providing an extrusion device in which the number of variants of shapes that can be produced is increased.
    This technical problem is solved by means of an extrusion device according to the characteristics of claim 1.
    An extrusion device according to the invention is configured to manufacture molded components. The extrusion device comprises a conveyor container and a delivery device for supplying a material to be extruded to the conveyor container. In addition, the extrusion device comprises a forming extrusion port as the output of the conveyor container. Therefore, through this extrusion port a component is provided through which the desired shape of the molded component to be manufactured is predetermined. An essential idea of the invention is that the extrusion port has a ring that is deformable in itself and which is formed by multiple links. For an embodiment of the extrusion port of this type, it can be deformed in the most varied ways, so that the output geometries can be adjusted more different and very varied, which is It is possible to adjust the manufacture of the most different and also very complex forms of a molded component to be manufactured. Thus, by means of the extrusion device according to the invention, the options for forming variants to be manufactured are considerably increased, without the extrusion device having to be transformed or even without having to have multiple separate extrusion devices available. In this way, the flexibility of use of the extrusion device is greatly increased.
    Preferably, the links for forming the ring are expected to be adjacent to each other. By this design, in the direction of the ring, it is then completely closed and, thanks to the adjacent positioning, radial leaks of the material to be extruded through the links of the ring can be prevented in the best possible way. Thus, by means of the adjacent positioning of the links, a practically continuous transition is also achieved, so that the outer surface of the molded component to be manufactured can be designed as uniformly and continuously as possible.
    Preferably, it is envisioned that the links are configured as a continuous link chain. In this way, the advantages mentioned above are further improved.
    Preferably, the links are provided to be movable radially outwardly or inwardly relative to the axis of the ring. These multiple movement options then provide the most varied position adjustment options for each link observed as such, where, if this is preferably applicable to all links, the most diverse and complex geometries can be adjusted in the circumferential direction around of the ring which, therefore, are predetermined by the shape of the ring.
    In an advantageous embodiment, it can also be provided that the ring is deformable to create free shapes. In this way, the possibility of the variants in which a molded component can be manufactured is clearly increased again.
    Preferably, the extrusion device is provided to have an adjustment device, which is configured to act on the links to change and maintain the position of a ring link. By means of such an adjustment device, the exact change of the position of one or several links can be facilitated, as well as the adjustment of the position of multiple links relative to each other with great precision. Also, also after adjustment, this position is permanently maintained very securely, so that no unwanted deformation of the ring occurs when the material to be extruded passes through it, and the design of the shape of the molded component that It has to be manufactured by individual adjustment of the shape of the ring can be generated with great accuracy.
    In particular, it is envisaged that the adjustment device is a hydraulic device with hydraulic pistons, where the hydraulic pistons act on the links to change their position in the ring and to maintain the position of the links. A hydraulic device as such is an extremely robust construction, which can apply the corresponding forces, in order to keep the links in position. This is also the case if the material to be extruded is pressed under great pressure through the ring.
    Preferably, it is envisioned that the adjusting device is configured to change the position of the links during the shaping of a molded component that is to be manufactured from the extrusion port. Through this design, during the manufacturing process of a molded component, the position or one or more links can be modified individually. In this way, a change in the shape of the ring in the longitudinal direction of a molded component to be manufactured can be made even during its manufacturing process, so that here also the complexity of the molded component to be manufactured can be clearly increased. . Therefore, it is not required that the shape of the ring remain unchanged once manufactured throughout the manufacture of a molded component, but that, through this possibility of adjustment when a molded component is manufactured, in different locations of a molded component they can therefore produce different geometries, in particular, cross-sectional components. In this way, the complexity of the molded components to be manufactured is clearly increased once again.
    In particular, it is envisioned that a non-stick device is configured to prevent adhesion of the material to be extruded to the extrusion port. The non-stick device is, in particular, a non-stick device that emits ultrasound. In this way, unwanted adhesion of the material to be extruded to the inner surface of the ring is prevented. Thus, ablation of unwanted material from the molded component to be manufactured and, therefore, an unwanted change in the outer contour of this molded component to be manufactured is also avoided.
    Preferably, it is provided that the extrusion device comprises a pressure measuring device, whereby the pressure of the material to be extruded is detectable in the extrusion port. In particular, the extrusion device further comprises a control unit whereby a change in pressure is adjustable depending on a change in the shape of the ring. In this way, you can respond to individual situations in a very specific way, so that there are no unwanted pressures at this output and, therefore, also not next to the ring. On the other hand, the necessary pressures in each case can be adjusted to the desired extent, so that a sufficiently strong expulsion of the material is given.
    In this context, the pressure detection, as already mentioned above, is an essential point to adjust the pressure conditions in the extrusion port respectively to the design of the respective individually adjusted ring shape. In particular, it is envisaged that, depending on a change in the shape of the ring, the resulting geometry will be determined and that, depending on that, the pressure adjustment will be determined and a corresponding adjustment made.
    Advantageously, the extrusion device is configured to manufacture molded components that comprise at least partially ceramic. Therefore, the material to be extruded is partially ceramic. For this same material, the manufacture of complex geometries of molded components is so far not possible enough. However, here in particular, the manufactured component is very expensive, so that, with the extrusion device according to the invention, production costs are reduced particularly in the manufacture of molded components made of ceramics.
    Advantageously, a molded component is a household appliance component that can be installed on a household appliance. A household appliance is configured to treat clothes, to wash dishes, to prepare food, or to store and store food.
    In particular, it is envisaged that, in the case of a change in the position of two adjacent links with a marked displacement of these two links relative to each other, in particular, a radial displacement out of two links similarly oriented in the direction of the hollow axis of the ring, the interface between the two adjacent links is covered by a cover, where this cover is an elastic material. In this way, large unwanted gaps that occur in the same way between the two links can be closed, and an unwanted radial leakage between these links of the material to be extruded is prevented.
    The extrusion device also has a heating device, whereby the material to be extruded is heated before reaching the extrusion port. Also, the extrusion device can also comprise a temperature sensing device, where the temperature is also detected in the extrusion port in order to adjust the respective process conditions depending on it.
    Therefore, by means of the invention it is possible that, by a single extrusion device and without a large transformation of the extrusion device, multiple different geometries for a molded component are achievable, in particular that the most varied complex geometries can also be generated. For this purpose, only this extrusion device is needed.
    Next, the embodiments of the invention are explained in more detail with reference to the schematic drawings. These show in:
    Fig. 1 a schematic view of an embodiment of an extrusion device;
    Fig. 2 a schematic perspective view of an embodiment of an extrusion port of the extrusion device according to Figure 1, in a first design of the shape of the extrusion port;
    Fig. 3 a view according to figure 2 with a design of the shape of the extrusion port that is different with respect to figure 2; Y
    Fig. 4 a view according to figures 2 and 3 with a design of the shape of the different extrusion port again.
    In the figures, the same elements and elements with the same functions are accompanied by the same reference symbols.
    In Figure 1, a schematic side view of an extrusion device 1 is shown, which is configured to manufacture the most varied molded components. The extrusion device 1 comprises a gear 2 and a motor 3. Also, the extrusion device 1 comprises a conveyor container 4 and a delivery device 5, which is configured to supply the material 6 to be extruded to the conveyor container 4. In addition, the extrusion device 1 comprises a forming extrusion port 7, which represents the output of the conveyor container 4, from which the molded component is generated.
    Likewise, it is envisaged that several heating zones 8 are provided next to the conveyor container 4, whereby the material 6 is heated in the conveyor container 4. By means of a conveyor unit, in particular a helical conveyor 9, the material 6 is directed to the direction of the extrusion port 7 shaper. It also preferably has heating zones.
    10.
    The extrusion device 1 also comprises a receptacle 11, on which the ejected molded component rests from the extrusion port 7.
    In figure 2, a schematic view of an embodiment of the extrusion port component 7 is shown. In this perspective view, it can be seen that the extrusion port 7 comprises a ring 12 which is deformable in itself and which It is made up of multiple links 13. For reasons of clarity, here only some of the links 13 with plate form are accompanied by the corresponding reference symbol.
    The links 13 are adjacent to each other to form the ring 12. It is also provided that the ring 12 composed of the links 13 is circumferentially closed, and that the links 13 are configured as a continuous chain of links.
    In the view shown in Figure 2, a simple design of the shape of the ring 12 is fixed, so that, in a schematic representation, a molded component 14 has a relatively simple geometry. The molded component 14 is made at least partially of ceramic and therefore constitutes a molded ceramic component. Specifically, the molded component 14 is a household appliance component for a household appliance.
    In figure 3, an alternative adjustment of the shape of the ring 12 is shown in a view corresponding to figure 2, where there is a more complex corresponding cross-sectional geometry, so that also the geometry of the molded component 14 has a clear complexity compared to figure 2. In this embodiment, it is envisioned that the position of links 13 is individually adjusted in comparison to figure 2.
    For this purpose, the extrusion device 1 comprises an adjustment device, which is not shown, but which is indicated by way of example with the reference symbol 15 in Figure 1, and which is configured to act on links 13 to change its position in ring 12 and to maintain the position of the links.
    Likewise, it is envisaged that this adjustment device 15 is in particular a hydraulic device with several hydraulic pistons, where in each case at least one hydraulic piston acts on one of the links 13 to change its position in the ring 12 and to maintain the position of link 13.
    It is also provided that the adjusting device 15 is configured such that it is adapted to change the position of links 13 during the shaping of the molded component 14 from the extrusion port 7. This also means that the position of at least one link 13 it can be inclined and / or that the inclined position of a link 13 with respect to the axis of the ring A, as illustrated, for example, in figure 2, can be modified. Thanks to these degrees of freedom in the positioning of a link 13, the changing formation of complex shapes of the cross-section for a molded component 14 is clearly increased, as is predetermined by the ring 12. By making a corresponding change in the possible position of a link 13, in particular, of all links 13, also during a manufacturing process, a molded component 14 can therefore be manufactured which, with respect to its longitudinal axis, can be manufactured
    5 on different sections of this one with different geometries of the cross section.
    In Fig. 4, another exemplary view corresponding to Figs. 2 and 3 is shown, where it is shown by way of example that a link 13 is radially shifted outward in large measure compared to its adjacent links 13, and that there is no uniform adjacency here, as is the case, for example, of Figures 2 and 3. By this type of step-by-step displacement of adjacent links, a gap can be created between two adjacent links, which can be covered by means of a cover element, which is not shown and is preferably elastic. In this way, a leak can be prevented
    15 of the material of the molded component 14 to be manufactured through said recess. As can be seen in the embodiment according to Figure 4, partial portions of the molded component 14 very specific locally and also in filigree can be generated in a simple manner.
    The extrusion device 1 has a control unit 16, by which the manufacturing process is controlled.
    Also, the extrusion device 1 comprises a measuring device of the
    pressure 17, whereby the material pressure §. to be extruded can
    detected in the extrusion port 7.
