Definitions

  • the invention relates to a method and a device for rising casting / low pressure casting - especially of light metal alloys - with a lying under a casting table Casting furnace with a riser and a mouth opening of the Riser and with a casting mold with bottom pouring hole and with a slide closure for the pouring opening, the forms a passageway which is for casting a substantially straight longitudinal course assumes.
  • the rising watering has the Significant advantage of a controlled controlled casting process.
  • the air bubble entry and the oxide skin entry associated with any swirling of the melt during casting, avoided.
  • this can be the detachment and entrainment of molding material in the Bleed and be avoided in the run, the otherwise to Reduction of quality of the GuB publishede leads.
  • a disadvantage of rising casting it is generally that the Solidification process of up to 15 min duration to be awaited must be removed before the currently filled mold and the next Casting mold can be brought over the casting furnace.
  • the Solidification process of up to 15 min duration to be awaited must be removed before the currently filled mold and the next Casting mold can be brought over the casting furnace.
  • US 3,627,018 is a process for the preparation of castings in a permanent mold known.
  • known methods an increasing casting process used, with a mold on a Melting container is placed so that a continuous connection between the melt container and consists of the mold cavity. After a complete Filling the mold with molten metal, the Casting mold via a positioning cylinder in horizontal Direction be shifted, so that no continuous Connection more between the melt container and the Casting exists.
  • a horizontal slidable barrier provided with an opening be provided and the connection between the Melting container and the mold by horizontal Move this barrier after the end of the Casting be interrupted.
  • a disadvantage of the US 3,627,018 known prior art is that before removing the mold from the respective one must be awaited closure mechanism provided until the melt at least at the bottom of the Fill opening of the mold is solidified. This results a slow process sequence.
  • the following invention is based on the object Method and apparatus of the type mentioned further to improve.
  • the Process sequence in the rising Casting / low pressure casting will be accelerated.
  • the solution lies in a method of increasing Casting / low pressure casting, where to shut off in Slider closure two directly to each other subsequent opening sections of the passageway Immediately after pouring while the melt is still liquid in the sprue transverse to the longitudinal course of Passage channel are shifted against each other, that an overhead opening portion with the pouring opening undercut remains open connected and one bottom opening section with the mouth opening the riser remains open, the Opening sections completely offset from each other lie.
  • the melt is within the upper opening portion of the passageway at the latest from the shifting of the opening sections of Passage channel actively cooled against each other.
  • a corresponding device is characterized characterized in that the slide closure on the Casting table is put on and two against each other slidable plates, each having a Having passage opening, wherein the plates for Pour with their openings in coverage are bringable and the plates to shut off like that are mutually displaceable, that the Passage opening in the upper plate with the Gutter is connected undercut open and open the passage opening in the lower plate with the Orifice of the riser is openly connected, while the sections of the passage opening completely offset from each other. It is according to the invention a neck approach of the holder of a coolant ring surrounded in the holder, with a coolant line connected is.
  • the melt within the sprue and optionally also within the upper longitudinal section of the passageway at the latest after shutting off i. So moving the longitudinal sections of the Passage channel to actively cool against each other. in this connection then can a mold already immediately after the Solidification of the melt in the upper longitudinal section of Passage channel and in the sprue of the mold be removed from the slide closure. A freezing of the entire casting must therefore not be awaited.
  • An air access to the melt level in the riser can be largely excluded if after shut off the melt in the riser only so far lowered is until at least the lower longitudinal portion of Passage channel is emptied of melt to a Sticking melt on the upper slide plate too avoid.
  • it may be provided in particular that after shutting off the melt in the riser only until slightly below the mouth of the riser is lowered and that the riser when lowering the Melt at the mouth opening with inert gas is charged.
  • the Process management characterized in that the casting mold itself as a whole together with the upper longitudinal section of the Passage channel of the slider member is moved.
  • the device according to the invention is designed so that the plates in a mounted on the casting table Cassette are held and the top plate in an in the cassette is held on the sliding holder the mold is placed. Especially this one Holder in a guided in the cassette slide be used on which it is resiliently supported.
  • a suitable casting mold has a lower cylindrical Spigot that forms the pouring hole and in one Nozzle insert or a nozzle holder in the holder suitable for the upper plate, which fits on the Passage opening is aligned in the upper plate.
  • the end face of the cylindrical nozzle of the mold dull on the upper Plate be placed and, provided the weight of the Mold is too low to ensure effective sealing produce, be braced against this.
  • To the Sequence of the casting operations as mentioned above accelerate are as coolers on Coolant ring on the nozzle insert or nozzle adapter in the holder of the upper plate and a cooling chamber provided below or in the lower plate.
  • the Coolant supply to the coolant ring must be elastic be to balance the movements of the carriage or the holder to be able to.
  • the actuator for the carriage can be arranged directly on the cassette.
  • the mold can be designed as a permanent mold or even out altogether Molded material exist.
  • the connection between riser and slider organ may be such that the riser the casting table in a Opening interspersed and immediately with a contact plate to the fixed lower slide plate applies.
  • a sprue bushing firmly used is, which lines the opening in the casting table and the sealing is stretched against the lower slide plate and that the riser with a contact plate against the lower edge this sprue bushing applies.
  • the riser can be connected to the casting furnace via a metallic bellows joint connected axially elastic and angularly movable be while the casting furnace is held vertically movable to a Applying the riser to the casting table and separating the To allow riser from the casting table.
  • a metallic bellows joint connected axially elastic and angularly movable be while the casting furnace is held vertically movable to a Applying the riser to the casting table and separating the To allow riser from the casting table.
  • the first to method refers and devices in which the melt level in the sealed casting furnace a controllable gas pressure is given up, the melt in the riser rise or fall back.
  • a controllable gas pressure is given up, the melt in the riser rise or fall back.
  • other methods and devices which promote the melt in the riser controllable can, e.g. Magnetic pump assemblies at the bottom of the riser in the pouring furnace.
  • a Slide organ 13 screwed on a casting table 11 having a passage opening 12 .
  • a sprue bushing 15 used at the same time a connection for the unillustrated riser of a caster forms.
  • a down for riser undercut-free opening 16 is provided.
  • the Slider member 13 comprises a cassette 17, the immediacy on the casting table 11 is screwed.
  • This cassette 17 has in turn a lower opening 18 which is aligned with the aforementioned Opening 16 is.
