Definitions

  • the invention relates to a method and a device for rising casting / low pressure casting - especially of light metal alloys - with a bottom casting furnace with a Riser and a mouth of the riser and with a mold with bottom pouring and with a Slider closure for the sprue, which has a passageway which forms a substantially straightforward for pouring Longitudinal course in particular a constant cross-section accepts.
  • the rising watering has the Significant advantage of a controlled controlled casting process. This will cause the air bubble entry and the oxidation skin entry, the with every swirling of the melt during casting goes along with it.
  • core packages as Casting can here the detachment and entrainment of molding material be avoided in the gate and in the run, the otherwise to Reduction of the quality of the castings 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.
  • the solution lies in a method for increasing casting / low-pressure casting, in which to shut off in the slide closure two immediately adjoining opening sections of the Passage channel immediately after pouring at still liquid Melt in the sprue transverse to the longitudinal course of Passage channel are shifted against each other so that a overhead opening section with the sprue opening undercut-free remains open and a bottom one Opening section with the mouth of the riser open remains connected, with the opening portions completely against each other are offset, and then the melt in the Riser lowered to below the mouth of the riser is, wherein the lower opening portion of the passage channel emptied of melt.
  • a corresponding inventive Device is characterized in that the slide closure comprises two mutually displaceable plates, the each having a passage opening, wherein the plates for Casting can be brought into overlap with their passage openings are and the plates to shut off so mutually displaceable are that the passage opening in the upper plate with the Gutter opening is connected undercut open and the Passage opening in the lower plate with the riser open is connected while the passages completely offset from each other.
  • the mutually displaceable plates can be in a linear Movement or in a rotating motion relative to each other to be moved.
  • the method is carried out in such a way that the melt in the riser after closing the Slider closure only slightly below the mouth opening of the riser is lowered to allow access of air to reduce a minimum. It is particularly favorable here, the Riser tube when slightly lowering the melt between the To apply to individual casting operations with inert gas, so that the oxidation is reduced at the melt level in the riser.
  • the mold behaves the riser when placing the mold with the part forming the mouth opening elastically yielding, the mold is placed on the riser that a defined Pad pressure between the slide closure and the mouth opening forming part of the riser. This can e.g. be made that when placing the mold this after a slight elastic yielding of the riser is caught by the casting table.
  • the mold can also be used in Guides are introduced across the casting table so that in the pouring position the riser a slightly depressed Position taken. Finally, when stuck on the Casting table spanned casting mold of the casting furnace with the riser until the construction of the desired contact pressure to the slide closure be moved up.
  • the riser the casting table in an opening interspersed and the mouth of the riser a little above the level of the casting table, the only for Placing the mold is used while riser and slide closure directly in contact with each other.
  • the upper plate slidable and the lower plate is fixed, wherein the pouring opening of the mold is larger is, as the passage opening in the upper plate, so that they the passage opening in the upper plate in the two Positions covered.
  • the top plate it is possible for the top plate to be fixed and the lower plate is slidable and the mouth opening of the riser is greater than the passage opening in the lower plate, so that it has the passage opening in the lower Plate covered in its two positions. In both cases Two-plate pushers are formed. Over the top plate can on the mold side also another in the context of the slider closure held base plate lie, the passage opening must correspond to the pouring opening of the mold.
  • connection plate with the mouth of the riser and the thus firmly connected Riser at one end of an elastic corrugated tube are fixed, and one firmly connected to the casting furnace Base flange with the other end of the elastic corrugated tube connected is. If a mold is lowered onto the riser, So this corrugated tube height and angle error of the connection level compensate the mold.
  • the riser carries at the upper end a connecting flange, on which a ceramic connecting plate is held, which forms directly the mouth of the riser.
  • the mouth opening is a slot and that the mouth opening widens downwards within the connection plate with small opening angles ( ⁇ 3 , ⁇ 4 ).
  • the backflow of the melt from the slide closure after shut-off is facilitated by the fact that the passage opening in the lower plate with a low opening angle ( ⁇ 2 ) widens downwards.
  • the passage opening in the upper plate with a small opening angle ( ⁇ 1 ) widens upwards.
  • the casting mold may be a permanent casting mold or, in particular, a be a core pack clamped in a mold frame.
  • a slide lock can be fixed be arranged while an actuator for the Slide lock fixed to the casting table on which the mold can be discontinued, may be appropriate.
  • each slider closure has an integrated actuator exhibit.
  • 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 casting furnace.
