[0003] Molding device and workstation of a system for producing concrete products for use with such a molding device
[0004] Description
[0005] The present disclosure relates to a molding device for producing a concrete product, in particular a hollow or at least partially hollow concrete product or tubular concrete product, such as a concrete pipe, a shaft base and / or other precast concrete parts, in particular by means of a casting process, and in particular by means of molds of the molding device having at least one outer shape, preferably standing.
[0006] Furthermore, the present disclosure relates to a workstation of a system for manufacturing concrete products for use in conjunction with such a molding device, in particular for opening the molding device at the workstation of the system for manufacturing concrete products, wherein the workstation may in particular be set up for preparing, oiling, cleaning and / or demolding the molding device.
[0007] background
[0008] Semi-automated plants and systems for manufacturing concrete products, particularly manhole bases and / or concrete pipes, are known in the prior art. The semi-automated production of these concrete products typically takes place using vibratory compaction or rotary pressing, where compaction and internal shaping of the concrete products are achieved by means of a roller head. Furthermore, it is known to produce individual, high-quality, tubular concrete products using a casting process in a stationary formwork. However, due to the longer curing times required for concrete, it is significantly more difficult to provide an automated production system that can automatically manufacture tubular concrete products using a cost-effective and high-quality casting process.In this context, prior art has proposed automated systems for the production of tubular concrete products, in particular concrete pipes, in which concrete products are transported in a circulation system between individual workstations of a production area by means of a form conveyor device and are produced in a casting process in an at least partially automated production cycle, controlled by program and clocked.
[0009] P10444PC Johann Schlüsselbauer - 2 - December 19, 2025
[0010] Ulrich Schlüsselbauer
[0011] Such a system for the automated or at least partially automated production of concrete products is described, for example, in DE 10 2012 217 324 A1, wherein the system comprises a production area with a plurality of automated workstations and a mold conveying device for transporting the molds or the outer mold and the optional mold core (as an exemplary inner mold) of molds between the workstations. Another such system is described, for example, in DE 102016 202411 A1. This system also comprises one or more manually operated mold assembly units with at least one assembly station for manually assisted assembly of a mold from corresponding outer and optional inner molds. A further such system is described, for example, in DE 10 2022 133 700 A1. This system also comprises a top sleeve installation station for attaching or inserting a top sleeve onto a mold.
[0012] For use in such systems for the production of concrete products, molding devices are typically used, which may include a casting mold with at least one outer mold and an optional inner mold, and / or other molding parts, for example to form a channel of a shaft base and / or lateral inlet or outlet openings on the concrete product.
[0013] A generic molding device for use in such systems is known, for example, from DE 10 2020 204 417 A1, which is shown by way of example in Figures 1A and 1B. Figure 1A shows a perspective view of the generic molding device 1000 for producing hollow or, in particular, tubular concrete bodies, and Figure 1B shows an exemplary top view of the generic molding device 1000. The generic molding device 1000 comprises a support section 100 on which an outer mold 200 comprising two outer mold sections 210 and 220 is arranged. The outer mold sections 210 and 220 of the outer mold 200 are arranged, by way of example, on respective slide sections 211 and 221.By means of the sled sections 211 and 221, which are slidably mounted on rails 110 and 120 arranged on the support section 100, the outer mold sections 210 and 220 can be moved apart or away from each other to demold a concrete body produced in the molding device 1000, in order to release the concrete body contained therein.
[0014] P10444PC Johann Schlüsselbauer - 3 - December 19, 2025
[0015] Ulrich Schlüsselbauer
[0016] During the setup process, e.g., before the next concrete pouring operation, the outer mold sections 210 and 220 can be moved towards each other or brought together again to be attached to one another in the state shown by way of example in Fig. 1A. In the set-up state according to Fig. 1A, the inner wall of the outer mold sections 210 and 220 forms, by way of example, essentially a cylindrical shape that at least partially forms the outer wall of the concrete body to be produced. The molding device 1000 further includes, by way of example, an optional mold core 300 forming the inner shape. The mold core 300, or rather its outer shape, forms, by way of example, essentially a (vertical) cylindrical shape that at least partially forms the inner wall of the concrete body to be produced. During the concrete pouring operation, in the state shown in Fig.In the setup state of the molding device 1000 shown in Figure 1A, concrete is poured into the space formed between the outer mold 200 and the mold core 300 to form the concrete body to be produced. For example, essentially cylindrical concrete pipes can be formed upright using the molding device 1000.
[0017] The generic molding device according to DE 10 2020 204 417 A1 offers significant advantages, particularly regarding a simple, efficient, and reliable way to open the outer form of the molding device for demolding to remove the manufactured concrete product and to close it again for the setup process before reuse to produce another concrete product. However, due to the wide support section, the generic molding device has a relatively large footprint, requiring relatively large storage areas for the curing of the concrete products in the respective molding devices. This makes efficient, space-saving storage of the molding devices more difficult and, for example, hinders the advantageous use of space-saving rack storage systems.In order to provide any manufacturing systems in which corresponding molding devices are used as efficiently and compactly as possible, it is therefore also desirable to design the respective molding devices as compactly as possible, while the handling of the molding devices with regard to setup and / or demolding should still be simple and reliable.
[0018] Starting from the systems and molds described above from the prior art, it is an objective of the present disclosure to provide a
[0019] P10444PC Johann Schlüsselbauer - 4 - December 19, 2025
[0020] Ulrich Schlüsselbauer
[0021] To provide a molding device for the production of concrete products, which continues to allow easy opening and closing of the outer shape of the molding device and can be designed to be more compact, particularly with regard to the base area of the molding device in the curing area of the system.

[0072] Fig. 2 shows a schematic perspective view of an exemplary mold 1000 according to several embodiments. Fig. 3 shows an exemplary schematic top view of the mold 1000 according to Fig. 2, and Fig. 4 shows an exemplary schematic sectional view of the mold 1000 according to Fig. 2 along the exemplary section line A-A according to Fig. 3. In the exemplary sectional view according to Fig. 4, a concrete product B is also shown, by way of example, curing or already at least partially cured in the mold between the outer and optional inner mold (for example, a hollow cylindrical concrete pipe).
[0073] The molding device 1000 comprises, by way of example, a support section 100, an outer mold 200 arranged on the support section 100, and an optional inner mold 300, here, for example, a mold core which may be designed, for example, as a shrinkable core and / or as a non-shrinkable, conical core. Essentially, the optional inner mold 300 is designed, by way of example, with a cylindrical shape (i.e., essentially cylindrical), and, by way of example, the outer mold is also designed, by way of example, as a hollow cylinder with an essentially cylindrical inner wall and an essentially cylindrical outer wall. In further embodiments, outer and / or optional inner molds may also be used which have angular (for example, square, rectangular, hexagonal, octagonal, etc.), round, oval, or otherwise shaped cross-sectional forms on the inside and / or outside.
[0074] By way of example, the outer shape 200 comprises a first outer shape section 210 and a second outer shape section 220, which together essentially form the outer shape 200. Thus, by way of example, the first outer shape section 210 forms a first outer shape half in some embodiments, and the second outer shape section 220 forms a second outer shape half in some embodiments. In further embodiments, additional movable outer shape sections and / or additional outer shape sections fixedly connected to the support section 100 may also be provided, i.e., by way of example, three or more outer shape sections that together form the outer shape.
[0075] The first outer forming section 210 on a first slide section is shown as an example.
[0076] P10444PC Johann Schlüsselbauer - 11 - December 19, 2025
[0077] Ulrich Schlüsselbauer
[0078] The first slide section 211 is arranged on the support section 100, for example, being displaceable in a first horizontal direction, and preferably, for example, being guided on linear guides 110 and 120, which are for example, arranged on the support section 100 and extend in the first horizontal direction. For example, the second outer molded section 220 is arranged on a second slide section 221, the second slide section 221 being for example, being displaceable on the support section 100 in the first horizontal direction, and preferably, for example, being guided on the linear guides 110 and 120, which are arranged on the support section 100. In some embodiments, the linear guides 110 and / or 120 can comprise one or more rail guides, one or more groove guides, and / or one or more sliding guides.
[0079] In the embodiment shown in Figures 1 to 3, the slide sections 211 and 221 are, by way of example, slidably held or mounted on the same linear guides 110 and 120. In further embodiments, the slide sections 211 and 221 can, by way of example, also be guided on separately provided guides on the support section 100, wherein preferably both slide sections 211 and 221, and with them the respective outer forming sections 210 and 220, are slidably guided on the support section 100 in the first horizontal direction, particularly preferably in opposite directions parallel to the first direction.
[0080] In some embodiments, the support section 100 can be designed as a solid support section 100 that forms the entire base of the molding device 100. In some further embodiments, the support section 100 can also be designed, at least partially, as a supporting frame, wherein at least the guides 110 and / or 120, for example as load-bearing guides, form or at least partially form the support section 100. In some embodiments, the extension of the support section 100 in the direction of the guides is defined at least by the length of the guides.
[0081] For example, the molding device 1000 is configured to be used in a closed state (in particular, for example, in a scaffolded state) to produce a concrete product (see, for example, Fig. 4), wherein the molding device 1000 is also designed to
[0082] P10444PC Johann Schlüsselbauer - 12 - December 19, 2025
[0083] Ulrich Schlüsselbauer is set up to be at least partially opened. The open or at least partially opened state of the molding device 1000 can be provided, for example, by partially opening the outer mold 200, for example, by sliding the outer mold sections 210 and 220 apart in opposite directions in the first horizontal direction.
[0084] The at least partially open state advantageously allows, for example, the demolding of the molding device 1000, i.e., the removal of an at least partially hardened concrete product from the molding device 1000, preferably by lifting or pulling it out vertically. For this purpose, the molding device 1000 can be opened only partially, so that a gripper of a lifting device or a demolding manipulator can be inserted from above to grasp the concrete product. Furthermore, the molding device 1000 can be cleaned, oiled, and / or prepared in the at least partially open state, whereby a greater degree of opening may be desirable for cleaning, oiling, and / or preparing the molding device than for demolding. This, too, can be advantageously facilitated, particularly in conjunction with workstations according to the embodiments described below.
[0085] Figures 2 and 3 illustrate that the support section 100 of the exemplary mold 1000 has essentially the same width and length in plan view and, in particular, has an essentially square base shape in plan view. In further embodiments, the corners may be rounded or a round shape may be provided. Polygonal, in particular hexagonal or octagonal, base shapes in plan view are also possible. Furthermore, it is possible to provide rounded or chamfered corners. As already described above, the support section 100 can also be designed, at least partially, as a supporting framework, wherein at least the guides 110 and / or 120, for example as supporting guides, form or at least partially form the support section 100.In some embodiments, the extension of the support section 100 in the direction of the guides is defined at least by the length of the guides.
[0086] The lateral edges or edge sections of the support section 100 are an example.
[0087] P10444PC Johann Schlüsselbauer - 13 - December 19, 2025
[0088] Ulrich Schlüsselbauer and the sled sections 211 and 212 in the closed state of the outer mold on opposite sides in the first direction in top view, i.e. in particular arranged in alignment one above the other; see e.g. Figs. 2 and 3.
[0089] Figures 2 and 3 illustrate that, in the first direction in which the outer mold sections 210 and 220 are displaceable (see, for example, Figure 5B), the slide sections 211 and 212 are essentially flush with the support section 100 when viewed from above in the closed state of the molding device 1000. In particular, unlike in the prior art described above, the support section 100 does not project horizontally beyond the edge of the slide sections 211 and 212 in the first direction when the molding device 1000 is closed. This allows for a more compact design and, in particular, a smaller footprint for the molding device 1000 than in the prior art described above. This can be achieved, in particular, by designing the slide sections 211 and 212 to project beyond the edge of the support section 100 in the first direction for opening the molding device 1000.to be pushed apart (see e.g. Fig. 5B).
[0090] In the context of the disclosure, a cantilevered method means, in particular, that at least parts of the outer mold and / or the slide sections supporting the outer mold parts can be moved in the horizontal direction beyond the support section and / or beyond the guides of the support section. Preferably, in some embodiments, a cantilevered method means at least that the slide sections supporting the outer mold parts can be moved in the horizontal direction beyond the guides, in particular beyond the longitudinal ends of the guides. In some embodiments, this can mean that sections of the outer mold and / or the slide sections already project in the horizontal direction when the outer mold is closed, and are moved even further beyond this point during methods for opening the outer mold.
[0091] In some further embodiments, it is also possible that sections of the outer mold and / or the slide sections do not yet protrude in the horizontal direction when the outer mold is closed, and in methods for opening the outer mold
[0092] P10444PC Johann Schlüsselbauer - 14 - December 19, 2025
[0093] Ulrich Schlüsselbauer can proceed after at least partial opening. This makes it advantageous to design a more compact footprint for the molding device, as lateral support and / or guide sections can be made shorter horizontally, while still allowing the outer mold to be opened easily and reliably.
[0094] In some embodiments, a locking device may optionally be provided on the molding device 1000, which is configured to lock the molding device 1000 in the closed state and / or to unlock it for opening the molding device 1000. In particular, the molding device 1000 may include a mechanically, pneumatically, hydraulically and / or electrically controlled locking mechanism.
[0095] Figs. 5A and 5B illustrate in exemplary top views the opening of a molding device 1000 according to Figs. 2 to 4, wherein Fig. 5A shows by way of example a closed state of the molding device 1000, and wherein Fig. 5B shows an exemplary, at least partially open state of the molding device 1000.
[0096] In the at least partially open state according to Fig. 5B, it is preferably possible to demold the mold 1000, i.e., to remove an at least partially hardened concrete product from the mold 1000, e.g., by pulling out and / or lifting the concrete product in a vertical direction, e.g., with a lifting device and / or a demolding manipulator or a handling device with a gripper for gripping the concrete product. Here, the at least partial opening of the outer mold 200 can be achieved by moving the slide sections 210 and 220 apart in the first direction, whereby, for example, the slide sections 210 and 220 can be moved cantilevered beyond the edges of the support section on opposite sides (see, e.g., Fig. 5B).Even with a small degree of opening, this allows the concrete product to be gripped from above with a gripper device or other demolding manipulator and removed upwards without any additional aids.
[0097] In some preferred embodiments, it is possible that the slide sections 211 and 221 are each designed to be displaceable by external force (in particular, for example, without their own drive). Thus, the slide sections 211 and 221
[0098] P10444PC Johann Schlüsselbauer - 15 - December 19, 2025
[0099] Ulrich Schlüsselbauer, with the corresponding outer forming sections 210 and 220, can be pushed apart in the horizontal first direction (see arrows in Fig. 5B) by external force. This can be done manually or by means of an external handling device. Alternatively or additionally, the forming device 1000 can include one or more drives for the driven movement of the slide sections 211 and 221 in the first direction, preferably hydraulic, pneumatic and / or electrically or electromagnetically actuated drive mechanisms.
[0100] Figures 6A to 6C illustrate, in exemplary top views, the opening of a mold 1000 at an exemplary workstation 500 of a system for producing concrete products according to some embodiments. This allows, for example, an advantageous opening of the outer mold to a greater degree, e.g., for cleaning, oiling, and / or, particularly preferably, for preparing the mold before filling it with concrete.
[0101] For example, the dashed line represents the area of a workstation 500 in a system for manufacturing concrete products using the molding device 1000, which can be transported, for example, by a mold conveying device 400 on guides 410 and 420, and thus be transported to and / or from workstation 500 from other workstations and / or from a curing area and / or mold storage area of the system. Workstation 500 can, for example, include facilities for setting up, cleaning, oiling, and / or demolding the molding device.
[0102] For example, the forming device 1000 can be moved into the work station 500 in a horizontal direction Y running transversely to the first direction X, in particular by way of example on the guides 410 and 420 of the forming conveying device 400 running in the second direction Y (see e.g. Fig. 6A).
[0103] For example, workstation 500 comprises two carriage mounting sections 510 and 520 opposite each other in the first direction X, each with guides 511 and 512 or 521 and 522 respectively running in the first direction X. A space is provided between carriage mounting sections 510 and 520 to accommodate the components in the

[0106] In this process, the slide sections 211 and 212 of the molding device 1000, which project beyond the support section 100, can move onto the respective slide receiving sections 510 and 520 of the workstation 500 in the first direction X during the opening of the molding device 1000 and are preferably guided by the guides 511, 512, 521 and 522 on the slide receiving sections 510 and 520 of the workstation 500. To achieve precise alignment of the respective guides of the slide receiving sections 510 and 520 with corresponding guides 110 and 120 on the support section 100, corresponding stop sections can preferably optionally be provided on the guides 410 and 420 and / or in the space between the slide receiving sections 510 and 520. This makes it easy to achieve a higher opening degree of the forming device 1000 at the workstation 500.
[0107] Fig. 7 shows a schematic perspective view of an exemplary molding device 1000 according to several further embodiments. In contrast to the preceding embodiments, in which guides 110 and 120 were guided, for example, on the support section 100 under the slide sections 211 and 212, corresponding guides 110 and 120 can alternatively or additionally be provided as outer walls with optional groove guides; see, for example, Fig. 7 and also Fig. 8. Furthermore, the support section 100 of the molding device according to Fig. 7 includes, for example, guide receptacles 140 extending transversely to the X-direction, which can be used, for example, for guiding on guides 410 and 420 according to Figs. 6A to 6C. The operating principle can otherwise be provided analogously to the preceding embodiments.

[0111] Workstation 500 can be provided, for example, as external lateral wall guides with optional groove guides.
[0112] Furthermore, it is shown by way of example that the slide sections 210 and 220 of the molding device 1000 can also be moved completely onto the slide receiving sections 510 and 520, thus achieving a maximum degree of opening with the outer molding sections 210 and 220 located away from the molding device 1000. This can also be made possible in the above embodiments.
[0113] Figs. 9A and 9B illustrate in exemplary top views the insertion of a molding device 1001 at an exemplary workstation 500 of a system for producing concrete products according to some further embodiments.
[0114] As an example, workstation 500 of Figures 9A and 9B is configured analogously to Figures 6A to 6C to accommodate a molding device 1000. Furthermore, additional guides 411 and 421 are provided as examples, which have a smaller track gauge (i.e., a smaller horizontal spacing) than guides 410 and 420, for example, to move smaller molding devices 1001 within the manufacturing system. In some embodiments, the molding device 1001 can be configured analogously to the molding devices 1000 described above, but, for example, with a smaller support section and, optionally, with a smaller outer shape, for example, to produce smaller-dimensions concrete products.
[0115] For example, the dashed line represents the area of a workstation 500 in a system for manufacturing concrete products using the molding device 1000, which can be transported, for example, by a mold conveying device 400 on guides 410 and 420, and a molding device 1001 on guides 411 and 412, and thus be transported, for example, from other workstations and / or from a curing area and / or mold storage area of the system to the workstation 500 and / or back. The workstation 500 can, for example, include facilities for setting up, cleaning, oiling, and / or demolding the molding device.
[0116] For example, the forming device 1001 can be positioned in a direction transverse to the first direction X.

[0119] For example, workstation 500 comprises two opposing slide mounting sections 510 and 520 in the first direction X, each with guides 511 and 512 or 521 and 521 respectively running in the first direction X, and further guides 512 and 513 or 523 and 524 of smaller track gauge for smaller forming devices 1001. A space is provided between the slide mounting sections 510 and 520 to accommodate the forming device 1000 brought in in the second direction Y (see, for example, Fig. 6B).
[0120] To accommodate the smaller forming device 1001, the slide receiving sections 510 and 520 can, for example, be moved towards each other in the X direction; see, e.g., Fig. 9B. The forming device 1001 can then be opened analogously to Fig. 5B, for example, by moving the slide sections 211 and 212 apart in the first direction X with the outer forming sections 210 and 220 arranged on them, and allowing them to be driven onto the slide receiving sections 510 and 520 on the guides 512 and 513 or 523 and 524 of smaller track width.
[0121] In general, according to some embodiments, molding devices always have at least one outer mold with at least two movable outer mold sections and, optionally, one or more inner molds (e.g., mold cores, channel molds, etc.) that can be positioned and / or are positioned within the outer mold. Molding devices according to some embodiments can be provided for various concrete products, e.g., for concrete pipes and / or manhole bases, etc. For example, molding devices can each have a stationary outer mold and, optionally, a mold core (as an exemplary inner mold) arranged within the stationary outer mold (possibly vertically). Outer and / or inner molds can be designed in one or more parts. The outer and / or inner molds can be designed according to the desired shape of the concrete body or precast concrete element (concrete product) to be produced.For example, one or more internal molds for the production of concrete pipes can have one or more essentially cylindrical mold cores. One or more internal molds can be used for...

[0123] Ulrich Schlüsselbauer explains that the production of shaft bases includes, for example, channel forms for a channel of the respective shaft base, which can be installed at least partially open at any assembly stations.
[0124] Optionally, according to some embodiments, the molding devices (or at least some of them) can further have, for example, a bottom sleeve on the underside, which serves, for instance, as a base for setting up the device and / or for locking the outer mold to an inner mold (e.g., a mold core). Such bottom sleeves can be removable or permanently attached to the inner mold or the inner mold core. Likewise, in exemplary embodiments, the molding devices (or at least some of them) can be closed from above with top sleeves after being filled with concrete.
[0125] Alternatively or additionally, depending on the requirements of the specific concrete product, further mold components and / or reinforcements or reinforcement cages can be provided on some of the prepared molding fixtures, as shown in some exemplary embodiments. Besides reinforcements or reinforcement cages, other structural components remaining in or on the finished concrete product can also be attached or fitted to some of the molding fixtures, for example, to install climbing aids or stirrups, or transport anchors that remain in the product. For special concrete products, these can also be other embedded components such as valves for livestock troughs or frames and / or grates for road drains. This can be implemented at the respective workstations of the system, which are designed as setup stations.
