Definitions

  • the present invention relates to a casting mold for producing a casting from a molten metal, which is, for example, a light metal melt, in particular an aluminum melt. Moreover, the invention relates to an apparatus and a method for casting such molten metal into a casting using such a mold.
  • a molten metal which is, for example, a light metal melt, in particular an aluminum melt.
  • melt container containing the molten metal.
  • a stopper which can be moved from a fully lowered position in which it closes the casting opening in a raised position, is released in the casting opening and melt through the feed channel into the casting mold can flow.
  • melt is conveyed against gravity from a docked to the bottom of the mold melt container via a arranged at the bottom of the mold gate into the mold cavity of the mold.
  • melt contained in the melt container is subjected to a pressure by which the melt is forced to flow through a riser acting as a feed channel in this case into the mold cavity of the casting mold.
  • the casting molds used in the known device have in their cover a straight into the mold cavity leading inspection opening through which a laser beam is directed to the surface of the melt filled in the mold.
  • the reflected from the melt beam is collected by a sensor which forwards its measuring signal to a control and evaluation, which determines the respective level of the mold based on the transmitted and received laser beam and upon reaching a critical filling level, a control signal for closing the spout opening of the melt container emits.
  • the critical filling level is adjusted so that, despite possibly trailing in the feed channel melt the dreaded pressure surge is avoided.
  • the object of the present invention was therefore to provide a casting mold in which it is possible to ensure a further optimized casting result even under the hard operating conditions which arise in practice.
  • a device and a method should be named, the use or application of which minimizes the risk of the occurrence of a stagnation during casting.
  • this object has been achieved according to the invention by providing such a mold with at least one compensation cavity has been provided, which is connected to the mold cavity via a channel and has at least one portion which is disposed above the maximum level of the molten metal during the solidification of the molten metal.
  • a molten metal pouring apparatus to a casting in a mold formed according to any one of the preceding claims, comprising a molten metal molten metal melting container having a discharge port connected to the pouring port and means for docking the molten metal Mold to the melt container such that the pouring opening of the mold in docked state is connected to the feed channel, equipped with a measuring device for detecting the amount of melt filled in the mold, with a control device for controlling the flow of melt from the melt container into the mold and with a control and evaluation device which detects the quantity of melt detected by the measuring device evaluates and outputs a control signal for closing the spout opening of the container upon reaching a certain level in the mold, the above object has been achieved in that the control and evaluation device outputs the control signal when the poured into the mold melt quantity reaches a limit has, in which the supply in the still existing amount of molten metal is sufficient to fill the mold cavity completely and the compensation cavity at most to a part.
  • the invention proposes to form a compensation cavity in the mold, which is designed so that it absorbs the buffer, the excess, no longer required for the complete filling of the mold melt amount, the process-related inevitably remains after closing the melt container in the feed, over which the melt flows into the mold. In this way it is prevented that the otherwise existing metallostatic pressure of the amount of melt present in the feed channel acts on the melt present in the casting mold.
  • the compensation cavity acts as a damper, by means of which, for example, the buffer layer which is particularly critical in the prior art with regard to the surface quality and further processibility of the casting obtained is effectively buffered.
  • the melt entering the mold cavity of the mold can escape into the balance cavity, in particular preventing the sudden pressure increase that occurs in conventional molds at the time of complete mold filling due to the conversion of the kinetic energy inherent in the melt into static energy.
  • Process and device allows the inventive design of a mold to interrupt the feed of melt into the feed channel already during the filling of the mold, the tolerance range within which this interruption takes place, by the buffer effect of Compensation cavity is increased. In this way, even under the rough operating conditions that occur in practice, it is ensured that the shutdown of the melt flow takes place in such a timely manner that the occurrence of pressure peaks in the casting mold is reliably avoided by taking into account the effect of the compensation cavity.
  • connection of the compensation cavity via a channel fulfills the one purpose, that the remaining in the region of the compensation cavity casting compound after solidification can be easily separated from the casting.
  • the channel is therefore preferably formed so that the remaining after solidification in the region of the channels webs are thin and easily severable.
  • the passage area of the melt to the chambers is preferably chosen as large as possible by the connection of the channel is formed as wide as possible for a given low connection height.
  • a particular advantage of the embodiment of a casting mold according to the invention is also that the compensation chamber is formed in the casting mold itself, so that the casting mold as a whole remains closed. This makes it possible to easily turn the mold, for example, to effect a targeted solidification of the casting.
  • the amount of melt remaining unused in the compensation chambers is negligible compared with the total volume of melt required for the casting.
  • a suitable filigree design of the respective connecting channel between the mold cavity and the compensation chamber which can accumulate in the chamber Casting material can be easily broken off the finished casting. It proves particularly favorable for the practical application of the invention that molds designed according to the invention can be used without problems in existing casting devices and that these already existing casting devices can be easily converted into devices according to the invention or operated in accordance with the invention.
  • the castings obtained by the use of the invention have a significantly smoother surface than those produced in a known manner. Particularly in the area of filigree mold elements of the casting, such as the oil passages of engine blocks, significantly lower surface roughness and a correspondingly lower flow resistance occur when flowing through liquids.
  • the castings obtained according to the invention can be cleaned in a particularly simple manner, since they only have slight adhesions to molding material after removal from the mold. The costs incurred for the cleaning of the finished casting effort is therefore significantly reduced.
  • due to the reduced pressure penetration of the inner surfaces through the melt it is also possible to reduce the requirement placed on the quality of the molding material used for the production of the casting mold. For example, cheaper coarse-grained molding materials can be used without impairing the surface quality.
  • a pouring device and a casting process are available with which even under the putting in practice hard Operational conditions ensure casting results that not only ensure optimized surfaces, but also allow simplified removal of the mold after the casting has solidified.
  • the possibilities of using casting molds according to the invention can be extended by limiting the cross section of the channel such that it is closed immediately after completion of the mold filling by already solidified molten metal. This can be achieved by matching the cross-sectional profile of the channel to the heat dissipation over the mold in the region of the channel so that the solidification of the melt contained in the channel is completed very quickly. Thus it can be prevented in a particularly simple manner that after the mold filling casting metal from the compensation chamber flows into the mold cavity and back. This proves to be particularly favorable for such casting methods in which the casting mold is rotated after filling with melt about a longitudinal or transverse axis in order to effect a targeted solidification of the casting.
  • the advantages of the invention can be used in all casting molds and casting processes, regardless of which material the casting mold is made of.
  • the good mold release makes the invention particularly suitable for lost molds, which are usually made of a molded material having a molding sand and a binder.
  • a particularly uniform effect of the design according to the invention of a casting mold can be achieved by in that a plurality of compensation chambers are provided which are connected to critical regions of the mold cavity, each time with regard to the effect of pressure peaks.
  • a larger chamber which is connected to the mold cavity via a suitably dimensioned connection channel or via a plurality of channels leading into the critical regions.
  • the casting mold can basically be provided for all known casting methods. By way of example, mention may be made of contact casting or rising casting in this respect.
  • the casting mold according to the invention can be provided for the production of castings for the automotive industry, in particular engine components such as cylinder blocks.
  • a structurally simple embodiment of a casting mold according to the invention results when the compensation chamber is connected to a portion of the mold cavity which lies at the top during the pouring of the molten metal.
  • the compensation chamber may be formed, for example, in the cover of the casting mold arranged at the top during filling.
  • the amount of melt conducted into the mold can basically be detected by a weight measurement or other known methods. Particularly safe and adapted to the actual conditions, the detection of the amount of melt can thereby be carried out in that the measuring device monitors the level in the mold and the evaluation device outputs the control signal when the molten metal in the Mold cavity has reached a level at which the then still existing in the feed channel molten metal volume sufficient to fill the mold cavity completely and the compensation cavity at most to a part.
  • the mold is advantageously provided with a leading to the mold cavity inspection opening for controlling the level of the molten metal in the mold cavity.
  • the compensation chamber and the inspection opening are preferably aligned so that the control opening to the mold cavity and the compensation cavity cut a common horizontal plane. In this way, the fill level of the chambers can be read in each case via the inspection opening.
  • the measuring device of the device according to the invention can be made of itself DE 196 23 720 A1 As is known, a laser, which directs a laser beam through the inspection opening on the surface of the molten metal filled in the mold, and a sensor which detects the laser beam reflected from the surface of the melt.

  • the equalization chambers 8, 9 may also be arranged in their rows at equal intervals in order to ensure the most equal possible distribution of their effect over the length of the casting mold.
  • the space occupied by the equalization chambers 8, 9 is small compared to the mold cavity 5.
  • the total volume of all the equalization chambers 8, 9 is about 2% to 3% of the volume of the mold cavity 5.

In this way, the upper section 8c, 9c of the compensation chambers 8, 9 are each above the maximum fill level F max of the casting mold 1.
  • the arranged below the maximum level F max of the mold 1 portion 8 d of the compensation chambers 8,9 is connected in each case via a horizontally extending, molded into the cover core 4 channel 10,11 to the mold cavity 5 of the mold 1.
  • the mold cavity 5 associated with the mouth of the channels 10,11 is respectively disposed on the mold cavity 5 facing the inside of the edge portion.
