Definitions
- the invention relates to a mold insert for molding machines for the production of compressed moldings.
- Mold inserts of this type are used, in particular, for the production of shaped concrete blocks and, together with a shaped frame, form a vibrating shape.
- the mold nests of the mold insert placed on a vibrating table are filled with concrete and sealed at the top by pressure stamps. Vibration excitation of the vibrating table compresses the concrete mass to such an extent that the moist molded bricks that are subsequently removed from the mold insert remain dimensionally stable and can be temporarily stored for final drying and hardening.
- Multi-layer manufacturers in which several layers of molded blocks are placed on top of one another without intermediate plates. For this purpose, the shaped blocks in the mold nests have to be removed even after the mold insert has been lifted off the vibrating table or, if appropriate, from an intermediate plate the shape nests are held and expressed for storage from the shape nests.
- the invention has for its object to provide an advantageous mold insert for multi-layer production.
- Both properties known per se are advantageously combined in such a way that the form-fitting engagement between depressions in the relief structure in the walls of the mold cavity and projections produced in these depressions on side faces of the molded body are dimensioned so large that, on the one hand, that (resulting from volume and material resulting) own weight of the molded body exceeding downward force is required for shaping the molded body, which is applied in a simple manner by vertical movement of the mold insert relative to the pressure device also used for compression, but on the other hand the positive engagement is so limited that the projections on the side walls of the molded body engaging in the depressions of the relief structure are not sheared off during the forced demolding and / or that there are no residues in the relief structure that go significantly beyond the normal dimensions of conventional mold inserts with flat walls.
- the relief structure also allows the use of mold inserts with hardened walls with very little material adhesion to the concrete mass of the molded body.
- the relief has, as support surfaces on which projections of the side surfaces of the compressed molded body are supported, holding flanks which are inclined downwards at an angle to the interior of the mold cavity.
- the angle of these holding surfaces against the vertical is preferably at most 30 °, so that during the forced demolding, the projections slide along the holding flanks with gradual lateral deformation of the material of the molded body, preferably within the range of elastic deformation.
- a slight permanent deformation of the projections on the side surfaces of the molded body is not critical, since the function of these projections to keep the molded body against its weight in the mold insert is eliminated after the molding.
- the weight of the shaped body depends not only on the volume but also on the density of the material, which, however, typically does not vary significantly, so that the weight of the compacted shaped body can be regarded as essentially known.
- the molded insert with the compressed molded bodies is typically moved vertically and possibly horizontally after compression, and acceleration forces occur here which do not yet cause the molded bodies to fall out of the mold insert allowed to.
- the depth of the relief structure can therefore be designed for high rigidity with low elastic deformability and the entire holding surface of all holding flanks for low rigidity with easy deformability of the compressed moist molded body within the scope of expected scattering.
- a depth of at most 1.5 mm, in particular of at most 0.8 mm, has proven advantageous for the relief depth of the relief structure.
- the minimum depth is advantageously 0.2 mm.
- the cumulative first cornering of all holding flanks in the wall-parallel horizontal direction is at least equal to the circumference of the molded body, preferably at least twice this circumference.
- the relief structure can advantageously have multiple holding flanks successively in the vertical direction, which are separated by sections of the relief structure that do not exert any holding forces.
- the relief structure contains concave and / or convex curvatures with a radius of curvature that is large, preferably at least ⁇ times that of the relief depth.
- Concave and / or convex curvatures can form a wave-like profile in direct succession.
- the relief structure can advantageously contain elongated, preferably essentially horizontal grooves, in particular with a constant cross section. In the case of polygonal floor plans, such grooves advantageously extend over more than half the distance between two adjacent corners.
- the holding flanks of the relief structure are preferably provided on wall surfaces opposite the center of volume of the mold cavity and / or in a rotationally symmetrical arrangement about a vertical central axis of the mold cavity.
- the terms of the depressions in the relief structure and projections on the side walls can in principle also be used interchangeably, but clearly relate to a preferred embodiment in which the mold cavity, preferably in the upper edge region, has at least one prismatic section with vertical wall surfaces without Has relief structure and the relief structure behind the continuation surfaces of this prismatic section.
- the relief structure is advantageously predominantly, in particular at least 60%, formed in the lower half of the vertical extent of the mold cavity. According to a further development, it can be provided that the clear cross section of the mold cavity widens downward in the course of the relief structure.
- FIG. 2 shows a molded block produced with the mold insert according to FIG. 1,
- FIG. 3 is a sectional view taken along A - A of FIG. 1,
- FIG. 4 shows an enlarged detail from FIG. 3,
- FIG. 5 shows a section corresponding to FIG. 4 with an alternative relief shape
- Fig. 6 is a view corresponding to FIG. 3 with a raised relief.
- a mold insert or a section of such a mold insert FE with several mold nests FN is sketched with a viewing angle from above into the mold cavities.
- the mold cavities are approximately rectangular and delimited by side or partition walls WS.
- the mold cavities are open at the top for the filling of non-compacted concrete mass and for inserting pressure plates of a pressure device which are tightly closed with the contour of the mold cavities, which is weighed down by a load or is otherwise pressed down into the mold cavities.
- the mold insert is placed on a vibrating table, possibly with the interposition of an intermediate plate, and pressed down by means of a mold frame not shown in the figure.
- the vibrating table is excited by shock vibration or unbalance vibration to vibrate, which is transferred to the filled concrete material and, under the influence of the pressure from the pressure device, compresses the concrete material in such a short time that the stones produced are still moist, but are dimensionally stable.
- the mold insert is placed on a shelf, for example a pallet as the first layer or on existing layers, after the compaction process has been completed while maintaining the relative position of the mold insert and printing device.
- a shelf for example a pallet as the first layer or on existing layers
- the mold insert including pressure plates can be moved sideways to over the pallet.
- the shaped stones are pressed out of the mold nests by the pressure plates of the printing device, which are not raised, and placed on the shelf or an already existing layer of shaped stones for drying and hardening.
- the wall surfaces of the walls WS which delimit the mold cavities are provided with relief structures RS which, in the sketched example, are present both on wall surfaces NWL running in the longitudinal direction LR and on wall surfaces NWQ running in the transverse direction QR Find.
- the relief structures have the shape of elongated, horizontally running grooves which, if necessary with interruption, occupy the major part of the wall surface in the horizontal direction. Several such horizontal grooves follow one another in the vertical direction.
- the relief structures RS extend in the sketched example over more than half the height of the side wall surfaces.
- recesses AA are provided in the side wall surfaces to form spacers on the side surfaces of shaped blocks.
- FIG. 2 shows an oblique view of a concrete block produced in a mold cavity FN of the mold insert FE according to FIG. 1, on the side surfaces of which both spacers AH and counter-relief structures GR are complementary structures to the relief structures RS and the recesses AA in the wall surfaces NWL, NWQ of Form nests have arisen.
- the edges at the transition from the side wall surfaces to the top surface of the concrete block according to FIG. 2 are chamfered by known shaping of the pressure plates used.
- FIG. 3 shows a detail of a horizontal view into a mold cavity cut open with a vertical sectional plane along A - A of FIG. 1.
- the relief structure RS is predominantly located in the lower half of the edge surface NWL and in the sketched example takes up more than half the height of the wall surface.
- the relief structure is interrupted by a cutout AA for a spacer.
- the two substructures each have the length RL, the total longitudinal extent of the relief structure with 2RL preferably being greater than half the longitudinal extent NL of the mold cavity.
- a printing plate DP a z. B. with a load applied pressure device is placed on this after filling the mold cavity.
- the relief structures consist of horizontal grooves NU, which, as can be seen more clearly from the enlarged section according to FIG. 4, are concavely curved away from the interior of the mold cavity.
- the grooves have a uniform curvature with a radius of curvature which is large compared to the relief depth RT of the relief structure.
- a compacted molded stone body produced in the mold cavity is positively connected with its side surfaces to the relief structures and is thus held in the mold cavity even after the supporting vibrating table has been removed, the holding forces absorbing the weight being applied to holding surfaces HF which are passed through the lower areas of the individual grooves are formed with surface tangents running downwards towards the mold cavity, whereas partial surfaces of the relief structure with vertical or with surface tangents directed downwards away from the mold cavity do not contribute to the holding forces.
- the total holding force that becomes effective for a molded body in a mold cavity is composed of the sum of the partial forces applied to all these holding surfaces HF.
- the long extension in the horizontal direction and the multiple succession in the vertical direction of the grooves of the relief structures result in a holding force which compensates for the weight of the molded body even at a low relief depth RT.
- the holding force exerted by the holding surfaces HF is limited by the fact that the molded body is still elastically deformable even after compression and along the holding surfaces HF with lateral compression downwards can be moved.
- the relief structures are dimensioned such that the weight of the molded body alone is not sufficient to deform the molded body to such an extent that the projections of the molded body lying in the relief structures overcome the relief downwards along the holding surfaces.
- the relief structures are dimensioned such that a deformation of the molded body using a force greater than its own weight force is possible to at least the extent without shearing off the projections of the molded body engaging in the relief structures that these projections overcome the relief structures downwards and the molded body out the nest of forms can be expressed.
- the relief depth RT is advantageously a maximum of 1.5 mm, preferably a maximum of 0.8 mm, in particular a maximum of 0.5 mm.
- the minimum depth RT of the relief structures is advantageously 0.1 mm, preferably 0.2 mm, in particular 0.3 mm. In the example outlined, a uniform relief depth is assumed for all grooves, which is preferred but not mandatory.
- FIG. 5 shows an embodiment of a relief structure in which the relief structure shows convex curvatures NX towards the interior of the mold cavity.
- the mode of operation is analogous to the relief structure according to FIG. 4.
- the mold cavity has a prismatic course in an upper region with unstructured vertical wall surfaces and a constant cross section in the vertical direction.
- the relief structure RS in the wall surface NWR is designed to be set back against the vertical extension of this prismatic section AP, as a result of which the corresponding prismatic upper section of the shaped body is not deformed by the relief when it is shaped downward.
- the relief structure RSX can also be towards the vertical extension of the prism surfaces of section AP towards the interior of the mold cavity.
- the pressure plate which typically maintains a gap of approximately 0.5 mm from the wall of the mold cavity, can be moved past the relief structure if necessary for molding.
- the depth of the cutouts AA for the formation of spacer elements on the side walls of the shaped body is typically much greater than the relief depth RT. These cutouts are open at the bottom, so that the spacer element AH formed on the molded body does not experience any compressive deformation when the molded body is molded from the mold cavity.
- the relief structures which can only be seen in FIG. 1 on one longitudinal and one transverse surface of the mold cavity are advantageously formed on at least two opposite wall surfaces or preferably on all wall surfaces.
- the holding forces can occur evenly and, on the other hand, they can be distributed over a large number of holding surfaces with a low relief depth.
