Definitions

  • the invention relates to a molded part of a modular concrete block mold.
  • a concrete block mold is assembled from several mold parts.
  • Concrete block molds are used to set shaped blocks.
  • An amount of concrete is poured into the concrete block form, and the concrete amount is compacted in the concrete block form by means of a block maker to create a concrete block.
  • the concrete block mold comprises a lower part of the mold, in whose one or more cavities the amount of concrete is filled, and an upper part of the mold with a stamp unit for compacting the amount of concrete in the cavities.
  • the stamp unit comprises pressure plates which can engage in the mold cavities of the lower part of the mold.
  • the lower part of the mold is open at the top and bottom, with the underside being closed by a horizontal pad.
  • the amount of concrete is poured through the upper openings of the mold cavities and then pressed through the pressure plates by being sunk into the mold cavities through the upper openings with a load unit. By shaking the base, the concrete mix solidifies to form stable molded concrete parts. In a final step, the molded concrete parts are removed from the mold through the lower openings in the mold cavities.
  • Flohlsteine are made using a concrete block mold in which cores are also placed in the recesses so that the amount of concrete is pushed into the space between the recess wall and the core.
  • the pressure plates used in the manufacture of fleas have cutouts whose shape corresponds to the core shape, so that the pressure plates can be pressed down along the upper core area during pressing.
  • a concrete block mold in modular construction comprises several mold parts that are detachably connected to one another to form the concrete block form.
  • the modular design allows the replacement of individual mold parts, so that when individual mold parts wear out, the entire concrete block mold does not have to be replaced and, in contrast to concrete block molds with permanently welded mold parts, the concrete block mold can be used more economically and sustainably.
  • the replacement mold parts like the mold parts of the concrete block mold, are made by conventional machining processes and / or casting processes.
  • the task is to provide an alternative mold part for a modular concrete block form.
  • the mold part of a modular concrete block mold for solving the task has an additively manufactured area or is an additively manufactured form part.
  • a molded part is generatively manufactured at least in some areas.
  • Another area of the molded part, if not entirely generatively manufactured, is manufactured conventionally, for example milled or cast.
  • the connection between generatively and conventionally manufactured Be rich can be made by suitable connecting means, for example welded connection, adhesive connection, fastening means such as screws or by printing the generatively manufactured area onto the conventionally manufactured area.
  • the molded part is made in one piece or in several parts.
  • Generative manufacturing also known as additive manufacturing, of mold parts has so far been unknown in mold making for block making machines. Automated processes that produce three-dimensional physical objects from a data set are called generative manufacturing processes. For this purpose, volume elements are stacked or joined in layers so that no mold-dependent tools are required. Generative manufacturing processes are also known as 3-D printing. Given the loads to which the concrete block mold is exposed, the mold part or at least its generatively manufactured area is advantageously manufactured from metal by means of a 3-D metal printing process. With 3-D metal printing, an energy source, such as a laser, sinks or melts a metal powder, usually in order to create the object to be manufactured in layers. The powder can be in a powder bed or projected using a nozzle. In this way, a metal additively manufactured area, that is to say a 3-D metal printing area, or a metal additively manufactured mold part, that is to say a 3-D metal printing mold part, can be manufactured.
  • 3-D metal printing an energy source, such as a laser, sinks or melts
  • a person skilled in the art can distinguish additively manufactured areas and molded parts from conventionally manufactured ones. Generatively manufactured areas and molded parts, especially if they are metal, can be identified as such based on their basic structure because of their manufacture from powder. Furthermore, they can be recognized as generatively manufactured by means of layers, in particular when combining different materia. In addition, the shape of generatively manufactured areas or mold parts also allows them to be recognized as such if such a shape could not be manufactured in a conventional manner.
  • additive manufacturing especially 3-D metal printing
  • 3-D metal printing allows great freedom in the design of the molded part.
  • 3-D metal printing can be used to produce shapes that could not be produced using conventional methods, such as undercuts.
  • Tool-related limitations of conventional manufacturing processes for example a limited selection of milling tools that would be associated with limited radii, do not apply to 3-D metal printing.
  • protruding embossments can be formed without milling radii.
  • many shapes can also be produced in a simpler way than with conventional production, for example Cavities.
  • the generatively manufactured mold parts offer increased functionality compared to conventionally manufactured ones. Geometry contours that cannot be produced conventionally can be easily produced using 3-D printing. Genera tively manufactured cavities result in a weight saving and an increase in the dynamic strength value. Furthermore, embedded additional functions can be provided by additive manufacturing in order to form heatable molded parts in this way.
  • the molded part can be designed to receive a heating element and / or has a heating channel. By means of heated mold parts, in particular pressure plates, the sticking of the concrete mixture to the surface of the mold part is reduced and the concrete mixture becomes easier to detach.
  • additive manufacturing not only shapes and contours, but also surface structures can be created in a simpler way than with conventionally manufactured molded parts. For example, scanned natural stone surfaces can be reproduced almost exactly. Structural surfaces with a high level of detail and particularly fine contouring, which conventionally could only be milled with micro tools, can also be created in this way.
  • Another advantage is that the molded part with an additively manufactured area or the additively manufactured molded part saves material in production, waste is minimized and there is no need to cut.
  • the molded part can have a conventionally manufactured milled or cast area as well as the additively manufactured area have, which can be associated with a combination of different materials.
  • the at least regionally generatively manufactured molded part has a first region made of a first material and a second region made of a second material. At least one of the two areas is produced generatively. Advantageously, both areas are produced generatively so that the additively produced area can include the first and the second area.
  • Molded parts that are less stressed by frictional wear are printed using a material that has a high tensile strength, for example the molded parts of the frame.
  • the first material can be one from the group comprising covering material, filler material and support material
  • the second material can be another material from the group comprising covering material, filler material and support material.
  • the shell material is used on the functional surface of the molded part. It is advantageously wear-resistant. The formation of a non-stick area is also conceivable.
  • the filling material fills free volumes of the molded part. It's usually easy and good printable.
  • the support material is used for areas subject to higher forces, such as stiffeners. It should have high strength.
  • the use of the mold part with a generatively manufactured area in a concrete block mold has another advantage in the event of wear, whereby wear not only means material wear and tear due to the running time, but also defects of all kinds. It is not necessary to replace the entire mold part if it is only worn in areas . Rather, it is sufficient to simply replace the worn area that has been manufactured using generative methods and, for example, to rebuild it by means of additive manufacturing.
  • the generatively manufactured area can therefore also be referred to as an exchangeable wear volume.
  • Mold parts with a wear volume enable groups of mold parts that are subject to wear to be further modularized beyond their individual mold parts, so that the corresponding concrete block mold can be viewed as a further modularized mold.
  • Generatively manufactured areas that are interchangeable are directly engaging areas of the mold parts, in particular the upper edge of the lower part of the mold in the main compression area, core tops, printing plate mirror and printing plate bevel as well as sword mirror and sword tip.
  • the printing plate mirror is the side of the printing plate facing the nest.
  • Their bevel is the beveled edge area, which is particularly stressed during lowering into the nest and by shaking.
  • the bevels of the nest edges in order to prevent or mitigate the impacts of the pressure plates, are also exposed to loads.
  • a sword is a pressure plate, one edge area of which extends to a point along the nest wall when the pressure plate is lowered, in order to form a shaped stone with an inclined side.
  • the choice of material for the concrete block mold and its at least Generatively manufactured molded parts are made in abundance.
  • the choice of material can depend on the wear-dependent pressure parameters and raw materials.
  • Concrete block molds which are only expected to be used for a few cycles, can be made of a different material or a different combination of materials than standard molds that are designed for a high cycle rate, or even concrete block molds for special applications. If the concrete block mold is planned to be used for only a few cycles, an inexpensive, easy-to-use material can be selected that is accompanied by a simple 3-D printing process. However, the mold part of such a concrete block mold is not as strong as that described below.
  • the powder selection for the 3-D printing of the mold parts is optimized with regard to the highest strength and service life values. Additional strengthening measures, such as heat treatment and coating, can be carried out during manufacture in order to achieve a longer service life for the concrete block mold.
  • the choice of material is based on the specific application. For example, higher-quality types of metal can be selected for particularly abrasive types of concrete, even if 3-D metal printing is more difficult and complex for such types of metal.
