Definitions
- the invention relates to a method for casting a casting, which is provided with at least one passage opening, from a molten metal.
- the castings in question are typically cylinder crankcases for high power internal combustion engines cast from cast iron material.
- cast iron with vermicular graphite is sometimes used instead of conventional gray cast iron or higher alloyed cast iron materials are used to achieve the required strength.
- the castings of the type described above are usually poured into molds, which are composed of several moldings and casting cores. While the mold parts typically determine the outer shape of the casting, the casting cores are inserted into the mold to image recesses, cavities, through holes, and the like on the casting to be produced.
- the moldings and cores are designed as permanent moldings and permanent casting cores or as lost moldings and casting cores. While permanent moldings and casting cores are made of materials that withstand the loads occurring during casting, and therefore can be used repeatedly for a variety of casting operations, lost moldings and cores usually consist of molding materials that can be easily destroyed by force or temperature. Is a mold completely or at least substantially of lost moldings and casting cores, one usually speaks of a lost form, whereas casting molds, the consist predominantly of permanent moldings, even then referred to as permanent casting molds when lost foundry cores are used in them. In the field of iron casting, lost molds are typically used, while in the field of light metal casting often permanent casting or combinations of permanent moldings and lost moldings are used.
- the molding materials that make up the lost moldings and cores are sands mixed with a suitable binder which, upon production of the respective moldings or cores, are solidified by a chemical reaction to the point of solidification into the mold cast melt have a sufficient shape retention.
- the constituents of the molding material can be coordinated with each other so that the respective casting core or the respective molded part breaks automatically during the cooling of the casting as a result of the stresses occurring in the process.
- the disintegration of the lost moldings and casting cores can be effected by the application of mechanically acting forces.
- cores can be destroyed by shaking the respective casting to such a small parts that their molding material trickles out of the casting automatically, or the destruction of the cores is accelerated by drilling, expressions or rinsing.
- the prerequisite for this, however, is in each case that the casting is substantially completely cooled, so that in the mechanical or thermal destruction of the lost casting cores and moldings occurring stresses lead to any damage to the casting.
- the process of cooling the casting has a decisive influence on its mechanical properties. Problems can occur during the cooling of a casting in that the casting part cools at different speeds due to non-uniform material distribution or non-uniform heat dissipation. As a result of such non-uniform cooling can lead to residual stresses of the casting, which can lead to a drastic deterioration in its mechanical strength.
- the cooling from the casting temperature to a temperature which is generally below 600 ° C. is carried out in a deliberately slow manner.
- the casting plants used in practice are equipped with cooling sections of a certain length, these cooling sections may additionally include so-called "cooling stations", where the molds can dwell with the castings to be cooled in them over a certain period of time to further delay the cooling , If there are no means available to guarantee a sufficiently slow cooling, or if even after such a slow cooling too high residual stresses on the casting are present, the castings must be subjected to an additional annealing to reduce the relevant voltages.
- the sand casting mold known from this publication for producing an aluminum alloy casting comprises a portion made by means of a solvent, in particular water, soluble binder, and another portion made by a binder which is not dissolved by the solvent in question can be.
- This division of the sections of the sand mold makes it possible to remove the core produced in each case based on the soluble binder by exposure to the solvent, for example by application of a jet of water, so that the inner areas of the casting exposed to the solvent cool more quickly than the rest of the casting.
- this solution only refers to cavities that are present in the casting, and requires a complex design of the sand mold made of different molding materials.
- document JPH03138068 A describes a method for producing a cylinder block, in which cooling gas is blown through a vent opening from below into the still existing in the cylinder liner sand core, once the temperature of the cylinder liner has reached the A1 transformation point.
- the object of the invention was to provide a method which makes it possible, with little expenditure on equipment, to produce through-openings having castings with optimized mechanical properties.
- the invention is based on the idea that, during the cooling of the cast part following casting of the molten metal by engagement with the casting mold, a state is produced by which the cast part in an interior region, which is decisive for its future loadability, can move at a speed which is significantly higher than the rate at which the casting would cool in that region when the casting mold is in conventional Continue to cool to room temperature in the state in which the casting has been made.
- a casting channel that penetrates the casting mold and is introduced through the at least one through-opening of the casting is introduced into the casting mold.
- cooling medium Through this passage then flows a cooling medium.
- the flow through the cooling medium causes the material of the casting surrounding the passage opening to cool much faster than would be the case if the casting mold remained closed in a conventional manner until the casting reached the prescribed final cooling temperature.
- cooling rates can be achieved which are higher than the cooling rates achieved on the outside of the casting mold become.
- the temperature gradient between inner and outer regions can thus be drastically reduced and, at the same time, the cooling rate of the cast part can generally be increased.
- thermally induced stresses in the casting are reduced to a minimum.
- strengths are achieved significantly higher than the strengths cast in a conventional manner and cooled in the mold without additional measures castings.
- the process according to the invention proves to be particularly effective in the production of castings from a cast iron melt.
- the minimum temperature at which the casting is maximally cooled (step c)) until the manufacture of the passage channel to be introduced into the casting mold according to the invention is set to be above the A 1 temperature at which it is used to convert the austenite comes.
- the minimum temperature, which does not fall below during cooling in step c) is typically in the range of 1153-600 ° C.
- the cooling medium may be, for example, air or another gaseous medium.
- air for example, air or another gaseous medium.
- water vapor or an air-water vapor mixture as the cooling medium.
- This effect can be promoted by aligning the casting with the casting mold or by making the through-channel introduced into the casting mold so that the main direction of the through-passage is vertically aligned.
- the existing in the passage or in each case inflowing and heated air can rise unhindered in the passage.
- the cooling medium can also be passed through the through-channel in a forced flow.
- a conveying device which may be, for example, a fan or a pump, be forced.
- the conveyor in question can be positioned for example in front of one of the outer side surfaces arranged openings of the passage channel or, if necessary, after insertion of the passage channel inserted into it.
- the procedure according to the invention can also be applied to cast parts which have a plurality of passage openings.
- a through channel is generated, which is then flowed through by the cooling medium in order to effect the invention accelerated cooling in the respective passage opening.
- the casting treated according to the invention is a cylinder crankcase for an internal combustion engine and the passage opening is at least one cylinder opening provided in the cylinder crankcase.
- the procedure according to the invention is particularly simple and at the same time inexpensive and flexible realize in practice that the mold is formed completely or at least in the region of the passage opening as a core package whose moldings and cores, which are arranged in the region of the passage opening and the extension of the through hole forming casting core, consist of a molding material under force - or temperature action decomposes.
- the casting mold consists of lost casting cores or molded parts, at least in the region of the passage opening of the casting to be provided with the passage, the casting cores and moldings concerned are made of conventional molded materials which, as explained at the beginning, are usually made of a sand, an organic or inorganic binder of course, wherein the molding material, of course, certain additives may be added to optimize its properties.
- the binder of the molding material can be designed in a manner known per se so that the binder, which ensures the dimensional stability of the molded parts and casting cores, is burnt by the heat introduced into the casting mold when the molten metal is poured therein. In this case, the affected casting cores and moldings automatically decay into small ones Pieces, which then also trickle automatically under exposure of the passageway from the mold or the casting.
- the casting cores or shaped parts assigned to the respective through-opening of the casting can be expressed, for example, by means of a punch, or the through-channel can be introduced into the casting mold by means of a drill.
- the at least one casting core forming the passage opening and the regions of the casting mold arranged in its extension are regularly removed completely in practice during the production of the passage channel.
- the through-passage can thus be guided through the respective through-opening of the casting, in particular by means of mechanical processing.
- the casting core forming the passage opening of the casting is only partially removed. Between the passageway and the inner surface of the through hole, there remains sand of the casting core, which still has a certain insulating effect. Accordingly, the cooling of the area adjacent to the passage opening does not occur as rapidly as would be the case with complete removal of the through-hole casting core and direct sweeping of the inner surfaces of the through-hole with the cooling medium, depending on the thickness of the remaining core material.
- the economy of the method according to the invention can be further increased by the mold having at least two mold cavities for the simultaneous casting of at least two castings and the molten metal is passed through a common sprue in the mold cavities of the mold.
- the device 1 for simultaneous casting of two cast parts Z1, Z2 comprises a casting mold 2 which is supported on a frame 3.
- the castings Z1, Z2 are conventionally designed cylinder crankcases, which are each intended for the construction of a row four-cylinder internal combustion engine.
- the casting mold 2 is composed of core moldings of outer moldings 4, 5, 6, 7 and casting cores 8 - 19 arranged in the interior of the casting mold 2.

- the respectively laterally arranged casting mold parts 5, 7 in each case form one end face of the respective casting Z1, Z2, while the respective casting cores 18 arranged opposite the respective associated outer mold part 5.7 represent the front side of the respective casting Z1, Z2 arranged here in the interior of the casting mold 2 ,
- the further casting cores 19 are used, for example, to produce water or oil passages in the cast parts Z1, Z2.
- the casting mold 2 is aligned so that the main direction H of the through holes 01,02 are aligned in the vertical direction V.
- the mold cavities 20, 21 of the casting mold 2 delimited by the mold parts 4 - 7 and casting cores 8 - 19 when the mold 2 is unfilled are connected via notches, which are not further shown, to a common, vertically aligned gate 22 arranged centrally in the mold 2.
- the central gate 22 is in turn connected to a likewise centrally formed at the top of the mold 2 sprue 23, via which the filling of the mold 2 with cast iron melt S takes place.
- the gate 22 and the other not shown here sections of the mold 2 are placed so that the filling of the mold cavities 20,21 counter to the effective direction R of gravity takes place.
- the casting mold 2 sits on a grid 24 supported by supports 24 of the frame 3.
- the outer moldings 4, 5, 6, 7 and casting cores 8 - 19 are made of a commercially available, inorganic binder and molding a sand mixed molding material which is solidified by heat and moisture removal to the extent that it has sufficient shape retention for the maintenance of the mold 2 and the forces occurring during the casting process.
- disintegration in particular of those moldings 4, 5, 6, 7 and casting cores 8 - 19, which are directly exposed to the casting heat of cast iron melt S, already begins.
- the temperature of the castings Z1, Z2 is still so high that hardened structure can be produced by accelerated cooling can. Optimally, the temperature is so high that the structure of the castings Z1, Z2 is still completely austenitic.
- through-channels G1, G2 are introduced into the casting mold 2 ( Fig. 4 ), of which in each case one of the through holes 01.02 of the casting Z1, Z2 is assigned.
- the through-openings 01, 02 of the castings Z1, Z2 which at this time have already partially decayed into smaller fragments Imaging casting cores 10 - 17 as well as in their imaginary Extension V1, V2 overlying portions of the lid of the mold 2 forming the outer mold part 4 and lying in their imaginary extension V1, V2 underlying, the crankcase K1, K2 with the crankshaft bearings L1, L2 casting cores 8,9 and also in the Extension V1, V2 below the casting cores 8,9 lying portions of the bottom of the mold 2 forming the lower mold part 6 from the mold 2 encountered.
- the ejected molding sections and foundry core fragments disintegrate into free-flowing, finely divided material M, which falls through the rack rust and collects at the bottom below the casting mold 2.
- the trickling out of the molding material M from the casting mold 2 can if necessary be assisted in a manner known per se by shaking, tapping or other mechanical treatments.
- the falling of the mold 2 down material M can be removed by a conveyor, not shown here.
