  • the present invention has the object based on creating a slide closure, which is designed so that with him a reliable and economical operation of a die casting device or the like in total and here the slide plate or closure parts a long Durability should have.
  • an on the Mold or the like attachable housing frame provided in which a detachable housing part is fixed, on which the spring organs held and the stationary Locking part and the slide plate are receivable.
  • the refractory Slide plate and the at least one closure part as Main component graphite, al-titanate or zirconium on.
  • Figures 1 to 3 show a slide closure 20, the for opening and closing a passage opening 13, 14th serves.
  • the slider closure 20 has an upper and a lower stationary closure part 21, 22 and an intermediate this movable slide plate 24, wherein this parts in contact with the melt from one refractory material are made.
  • Andeutungjan is of a Druckgiess driven, which preferably for the rising pour one Alloy alloy is used, the upper end riser 11, 12 seen from a casting furnace through which the Melt up in a partially shown mold 15 is brought, this ever a through hole 13, 14th is provided, wherein between the riser 11, 12 and the mold 15, the slide closure 20 with the closure part 21 and the slide plate 24 is arranged.
  • the slide plate 24 is by means of spring organs 25 to the upper stationary closure member 21 or by other means to the lower closure member 22 pressed.
  • the upper closure part 21 and the below this sliding slide plate 24 are of the spring organs 25 pressed together and assigned to the mold 15, Meanwhile, the lower closure member 22 the riser 11, 12 is assigned.
  • the slide plate 24 is at Placing the mold 15 on the casting furnace close to the upper sliding surface 22 'of the closure part 22 is pressed, the means for this pressing by its own weight the mold 15 and / or by an additional not shown in more detail can be provided Verspannstoff.
  • This bracing means may for example be a docking mechanism be by means of which the mold on the stove is positioned and tightened.
  • the lower closure part 22 has one to the top 16 'of the riser protruding collar 22 "on, the Such a height and width, that the spring organs 25 with rocker arms 26 engage under the slide plate 24 on both sides can.
  • the slide plate could 24 on its underside a corresponding collar exhibit.
  • Housing frame 32 is provided in which a detachable Housing part 35 is fixed, on which the spring elements 25 held and the stationary closure part 21 and the slide plate 24 are receivable.
  • the housing frame 32 and the detachable housing part 35th have mutually corresponding guide surfaces on both sides 33, 34, wherein the one guide surface of the housing frame 32 so approximately in their longitudinal extent is slidably held, that the housing part 35 in it tensioned or can be solved by the same.

  • the guide surfaces 33 of the wedge 33 'and the Housing part 35 are to the direction of displacement of the wedge 33 'arranged at an angle of several degrees, so that in position 36.2 a non-releasing wedge bracing arises.
  • the riser has a refractory pouring tube 11 and a this holding metal tube 12 with an upper flange 12 ', which is mounted on a bellows 17.
  • This advantageous made of a sheet metal bellows 17 is provided with such rigidity that with the lower Closure part 22 a limited floating storage is formed, so that a whole-area concern when Pressing the slide plate 24 against this closure member 22 and thus an optimal seal between the two is guaranteed.
  • the spring members 25 have - as in Fig.2 it can be seen - on both sides of the plate 24 each one Rocker arm 26, each articulated on tabs 28 and from spring elements 29 on the plate 24 facing away Side is applied, such that the front Ends of the rocker arm 26, the slide plate up against push the closure member 21, which in a housing frame 32 is held.
  • the housing frame 32 is in turn attached to the bottom of the mold 15. Further is still one with the slide plate frontally coupled Drive rod 33 indicated that not one listened closer shown drive member.
  • This pressure casting device is characterized by that the successively to be filled with melt molds easily and quickly positioned on the casting furnace, filled and replaced by a next mold can.
  • the housing frame 32 is with its underside 32 'preferably on the side facing away from the drive member above the lower sliding surface 24 'of the slide plate 24 arranged. This allows the mold 15 together with the slide fastener attached to its underside 20 in the longitudinal direction of the slide plate 24 in the way that the collar 22 "of the belonging to the casting furnace closure member 22 between the Rocker arm 26 comes to rest and the mold 15 after Reaching the casting position on this closure part 22 can be lowered.
  • FIG. 4 shows a variant of a pressure casting device, which in itself the same as that of Fig.1 constructed is therefore referred to the above explanations.
  • the lower one stationary closure member 42 not the riser 41, but associated with the mold. Accordingly are the upper and lower closure members 21, 42 as well the slide plate 24 of rocker arms 46 of the spring members 45th braced against each other in the frame 32.
  • This lower one Locking part 42 arrives when the casting mold is introduced the projecting collar 41 'of the riser 41 to lie. This offers the advantage that there is no shift between these two takes place and that between the slide plate 24 and the upper and the lower closure part 21, 42 a defined clamping force is present.
  • FIG. 5 shows a slide closure 50 which is in the Difference from that of Figure 1 not on the mold 65, but on the suggestively shown casting furnace 61 is attached.
  • the simplified illustrated mold 65 is accordingly at the remaining on the mold Slide lock 50 attached and released again.
  • the slider closure 50 has a the casting furnace 61 mounted housing frame 52 in which a lower stationary refractory closure part 63 frontally of a clamping screw 66 or the like is fixed.
  • the sliding above the closure part 63 arranged slide plate 54 is in a slide frame 56 held in turn by one of a drive member 69 adjustable slide 57 is taken.
  • This Slider 57 is guided on slide rails 58, the top of Case frame 52 are attached.
  • the slide plate 54 and the adjacent thereto Locking part 53, which form the closing surface are each provided with such passage openings 53 ', 54', that they are starting from the closing surface in diameter are extended upwards or downwards. This can be the in the passage opening 54 'of the slide plate 54th solidified melt when removing the mold 65 easily be taken out.
  • a refractory Plate unit provided, which consists of at least one stätiondid Closure part 21, 22, 42, 53 and a slide plate 24, 54 exists in which the following material combinations used in the production:
  • the invention is with the embodiments explained above sufficiently demonstrated.
  • the construction of the casting furnace with the riser can of course other than look like this.
  • the riser could even an upper plane end face and thus the Make a closure part on which the slide plate would be slidably arranged.
