Abstract: A mold frame for the production of molded pieces, comprising at least one mold cavity, the at least one mold cavity being defined by a plurality of mold walls, wherein at least one mold wall of the mold cavity is a mold wall that is displaceably attached to the mold frame, and comprising at least one heating element for heating at least a part of the mold frame.

Abstract: A concrete mold including a mold frame with a frame body and at least two rows of teeth formed on the frame body lying opposite one another and in each case facing a mold insert. The mold insert has an insert body and at least two rows of teeth arranged on the insert body lying opposite one another and in each case facing the mold frame. Recesses are in each case formed on the insert body between teeth of its rows of teeth, in which recesses teeth of the rows of teeth of the frame body in each case engage in the assembled state of the mold. Recesses are in each case formed on the frame body between the teeth of its rows of teeth, in which recesses the teeth of the rows of teeth of the insert body in each case engage in the assembled state of the mold.

Abstract: In summary, the invention concerns a mold frame for the production of molded pieces, comprising: at least one mold cavity, the at least one mold cavity being defined by a plurality of mold walls, wherein at least one mold wall of the mold cavity is a mold wall that is displaceably attached to the mold frame.

Abstract: A mold (for producing molded blocks with at least one lateral face which has a texture, wherein the mold comprises at least one flexible belt, wherein the flexible belt surrounds at least one mold wall of the mold lower part that delimits the mold cavity in order to act on the material for producing the molded block that is received in the mold cavity, and in order in so doing to impress a texture on at least one of the lateral faces of the molded block, wherein the flexible belt can be moved relative to the mold lower part and wherein the flexible belt is mounted in such a way that it moves around the mold wall when the molded block is ejected from the mold cavity. Here, the mold comprises an active auxiliary device by means of which a rolling resistance of the flexible belt can be varied.

Abstract: A device is provided for monitoring and controlling a machine having at least two sensors for recording measurement variables, particularly motion variables, and with an electronic control loop for evaluating the recorded measurement variables and correspondingly controlling machine components of which the measurement variables can be influenced.

Abstract: The invention relates to a mold for the production of molded parts on a jolting table, the mold having a mold frame which carries a mold insert in which recesses defining the molded parts are formed, the mold insert being surrounded by a clearance space toward the mold frame, this clearance space being at least partly filled with damping means which keeps the mold frame and mold insert at a distance apart in a non-contact manner. In this case, at least one locking element passes through the clearance space, the locking element being mounted with play in at least one of the mold frame and mold insert.

Abstract: A mold for producing concrete articles having a mold bottom part that includes a molded chamber block having a substantially uniform thickness and side parts attached to the molding chamber block by fasteners. The molding chamber block has molding chambers located in an inner region and cutouts located on an edge region. The cutouts form intermediate webs of approximately uniform width, and at least a portion of the cutouts are undercut slots having lateral openings. The fasteners attach the side parts to the molding chamber block via the undercut slots of the cutouts.

Abstract: A description is given of a mold for manufacturing concrete moldings, e.g. paving setts, large-volume blocks and large-format, thin panels, having a bottom mold part which comprises the mold chamber(s) and having a top mold part with a load plate and the die or the dies. The bottom die parts (47) which come into contact with the concrete in each case are guided so as to be movable in the vertical direction, with respect to the top mold part, in a displacement range defined by stops (46, 51, 53) and are exposed to the action of a pressure medium, e.g. a bellows (40) activated by compressed air. The manufacturing process claimed works with two successive fillings. After the first filling pre-compaction is carried out at a relatively high pressure, and after the second filling secondary compaction is carried out at reduced pressure, the reduced pressure resulting in desired striking of the movable die part against the other die in the same rhythm as the vibrations.

Abstract: Concrete-molding machine having a ram on which an upper mold part is fastened in a releasable manner. The quick-fastening device used for this purpose comprises connecting pins which have a shank and a widened cross-piece. In order to simplify the device, the connecting pins are fastened on the upper mold part by means of their shanks. Located on the ram or on a carrying plate fixedly connected thereto is a horizontal slide with keyhole-like clearances into which the connecting pins can be inserted from beneath. Pneumatic lifting elements grip below the slide and draw it up, in the connecting position, to the cross-pieces.

Abstract: An arrangement for producing a molded concrete article which has a surface including zones at varying levels. The arrangement includes three groups of punches defining respective impression depths into the concrete article, and a molding device including three head plates, each of which is connected to a corresponding one of the groups of punches. An upper head plate is connected to a group of punches having a deepest impression depth. A lower head plate disposed below the upper head plate is connected to a group of punches having a shallowest impression depth.

Abstract: The process described serves for producing a steel mold for concrete paving setts with so-called spacers, the individual mold chambers being cut out of a steel plate by flame cutting. Grooves are formed in the mold walls by means of the flame-cutting jet, by way of an arcuate movement of the same, the grooves defining the cross section of the spacers. The upper section of the grooves is filled in that closure platelets, of which the cross section corresponds approximately to the cross section of the groove and which exhibit welding projections on their side directed towards the groove, are welded into the groove by projection welding. The closure platelets consist of a strain-hardened unalloyed or low-alloyed steel.
