Definitions

the invention relates to a method and a device for the production of moldings, in particular shaped concrete blocks made of flowable concrete, with one below and one above open form and one or more form nests, which one or several mold cores for making recesses the outside and / or on the underside of the molded body are assigned, wherein a core carrier carrying the mold cores for moving the mold cores in and out of the mold cavities is movable in the vertical direction.
Another disadvantage is that for transferring the vibrating forces from the base plate to the form of distance means used due to the Division of base plate and core support plate also must be divided and thereby the transfer of vibratory forces affect.
Another disadvantage is that the Core carrier plate when pulling out on the form boards of the The vibrating table slides on which the concrete blocks are placed become. Because the form boards have dimensional tolerances in height and Have unevenness caused by wear, can move when moving out or retracting the mold boards are disturbed.
the invention has for its object the process flow the mechanical production of Improve and simplify concrete moldings.
the core carrier can be made open at the bottom, so that liquid concrete that is between the recesses of the Cover plate of the base frame and the cores down emerges, not between the core carrier and cover plate can build up.
FIG. 1 shows a molding machine 1 in the working position with a lowered mold 2 and into the mold nests 3 retracted mold cores 4.
the mold cores 4 are on one Core support 5 attached, the vertical in a base frame 6 is movably mounted.
An upper cover plate 7 of the base frame 6 is with recesses 8 for the passage of Mold cores 4 are provided.
the rectangular base frame 6 consists of two lateral ones Side members 9 made of flat steel material and the upper cover plate 7. At the bottom of the cover plate 7 are vertical downward support strips 10 attached, with which the base frame 6 on a form board 11 of a vibrating table 12 is supported.
the support strips 10 are each arranged and extend between the recesses 8 parallel to the side members 9.
Task of Support strips 10 is the shaking movements of the vibrating table 12 to transfer to Form 2 without interruption.
rollers 13 are mounted with which the base frame 6 together with the core support 5 on two side Rails 14 under the raised form 2 retractable and extendable is.
the rails 14 are attached to a frame 15 (Fig. 6) and laterally offset from each other (Fig. 2).
rollers 13 are laterally offset, so that the front rollers 13 on the outer and rear ones Rollers 13 run on the inner rails 14.
Each of the four Rails 14 has a slant at its front end front and bottom ramp 16 for the rollers 13, so that the base frame 6 at the end of its horizontal movement vertically down onto the form board 11 of the vibrating table 12 is lowered.
a control member in the form of a control rod 17 also horizontally movable parallel to the rails 9 stored (Fig. 4 and 5).
the control rod 17 two elongated holes 18, in each of which a guide pin 19 of Side member 9 engages movably.
an oblique slot 21 is arranged in each case Direction of movement of the control rod 17 obliquely forward and runs down.
the core carrier 5 consists of a front and rear Cross member 23, which are arranged in pairs, parallel extending to the side members 9 of the base frame 6 Support strips 24 are interconnected.
the mold cores 4 are each of two support strips 24 attached by screws 25.
the support strips 24 are at their upper end tapered so that an upward wedge 26 results in the concrete residues down on the side surfaces slide.
the top of the Support strips 24 In the area of the mandrels 4, the top of the Support strips 24 not tapered, but forms a flat Surface on which the mandrels 4 are screwed can.
the vertical guidance of the core support 5 in the base frame 6 is carried out by two vertical guide rods 27, which in Area of the four corners of the base frame 6 at the bottom the cover plate 7 are welded and the cross member 23rd of the core support 5 vertically freely movable between them take up.
the two control rods 17 are at their rear end each with a drive means connected in the embodiment is a linear actuator 28 known per se.
a linear actuator 28 known per se.
the control rods 17 are with the linear drive 28 by means of a vertical bolt 29 connected in a bore 30 one with the control rod 17 connected drive rod 31 engages movably. This allows the vertical movement of the base frame 6 can be compensated for relative to the linear drive 28.
Fig. 6 At the beginning of the process sequence (Fig. 6) is the Form 2 in the raised position over the form board 11 of the Vibrating table 12.
the linear drive 28 that acts on the control rods 17 (Fig.4) becomes the base frame 6 together with the lowered core support 5 on the Rails 14 moved horizontally under the form 2.
the rollers 13 slide Base frame 6 down the ramps 16 until the base frame 6 with its side members 9 and the support strips 10 rests on the form board 11 (Fig. 7).
the linear drive 28 is programmed so that the base frame 6 is exactly below the Form 2 is positioned and its correct position to the mold nests 3.
the form 2 in lowered in a known manner and on the cover plate 7 of the Base frame 6 and locked with this (Fig. 7 and 8).
Fig. 8 shows an embodiment of the lock between shape and base frame.
a vertical one Locking pin 32 on both sides of the form 2 engages with Lowering the form 2 into a hole in the cover plate 7 of the Base frame 6 and prevents further horizontal movement of the
the base frame 6, core support 5 and the control rods 17 existing unit relatively low be built.
the mandrels 4 are not are conical, but for example cylindrical, the mold cores 4 must have the full extent of their height are pulled out of the mold nests 3. This is a correspondingly larger vertical lowering of the core support 5 downwards and a larger overall height of the base frame 6 required.
