Definitions
- a water jacket is provided in the cylinder crankcase, which covers the cylinders on both sides and which has a central inlet and a central outlet with both sides of the water jacket are flowed through approximately equally and thus a uniform cooling of the cylinder both sides takes place.
- Out DE-37 07 256 C is a one-piece core element for the production of cylinder crankcases for piston engines known, which is integrally formed from sole core and the two sheath cores.
- the two water jacket cores are not open at the front, so that there is a clear and reliable fixation in the mold for such a core element.
- the cylinder crankcase according to the invention however, can not be made with such a core element.
- Out DE-100 58 428 A is a plan view of a finished cylinder block showing a water jacket for a piston engine with cylinders in a row, the water jacket is open at the front.

- Out DE-G 90 16 902 is to remove a water jacket core clasp consisting of three parts, which is designed as a plug-in element.
- This known core brace requires that the water jacket dividing cores are each made by themselves and then assembled together over the center piece of the core clip and then connected to the associated sole core.
- the disadvantage of such an arrangement is that the water jacket core must be assembled in a separate joining operation before it can be joined together with the sole core.
- the invention has for its object to provide a mold core assembly for the casting of an engine block of the type described above, which is easier to assemble.
- the particular advantage of the invention is that in the manufacture of the two water jacket cores, the fasteners are inserted into the core mold and involved in shooting the core molding compound, so that after curing of the core molding compound of this core consisting of two partial cores handled as a unit and with the Cylinder core having sole core can be assembled into a complete core assembly.

Abstract
Description
Bei wassergekühlten Kolbenmotoren mit in Reihe angeordneten Zylindern ist im Zylinderkurbelgehäuse ein Wassermantel vorgesehen, der die Zylinder auf beiden Seiten überdeckt und der einen zentralen Zulauf und einen zentralen Ablauf aufweist wobei beide Seiten des Wassermantels in etwa gleichmäßig durchströmt werden und so eine gleichmäßige Kühlung der Zylinder von beiden Seiten erfolgt.In water-cooled piston engines with cylinders arranged in series, a water jacket is provided in the cylinder crankcase, which covers the cylinders on both sides and which has a central inlet and a central outlet with both sides of the water jacket are flowed through approximately equally and thus a uniform cooling of the cylinder both sides takes place.
Bei Motorkonzeptionen mit mehreren Zylinderbänken, beispielsweise V-Motoren, wurde festgestellt, dass eine differenzierte Kühlwasserführung zweckmäßig ist und zwar in der Weise, dass der Wassermantel je Zylinderreihe geteilt wird, so dass beispielsweise bei einer V-Anordnung die einander benachbarten Wassermäntel jeweils von einem größeren Volumenstrom je Zeiteinheit durchflossen werden als die beiden außenliegenden Wassermäntel.In engine concepts with multiple banks of cylinders, such as V-engines, it has been found that a differentiated cooling water flow is appropriate in such a way that the water jacket per cylinder row is shared, so that, for example, in a V-arrangement, the adjacent water jackets each from a larger Volumetric flow per unit of time are traversed as the two outer water jackets.
Das Gießen eines derartigen Motorblocks mit geteiltem Wassermantel bereitet hinsichtlich der Gestaltung der Kernanordnung für die Gussform Schwierigkeiten, da jeweils ein gesonderter Einzelkern für jeweils einen Teilwassermantelkern hergestellt ist und nicht zuverlässig und maßgenau auf dem Sohlenkern fixierbar ist.The casting of such a split-water engine block is difficult in terms of the design of the core assembly for the mold since a separate single core is made for each partial water jacket core and can not be reliably and accurately fixed to the sole core.

Der Erfindung liegt die Aufgabe zugrunde, eine Formkernanordnung für das Gießen eines Motorblocks der vorstehend bezeichneten Art zu schaffen, die einfacher zusammenzufügen ist.The invention has for its object to provide a mold core assembly for the casting of an engine block of the type described above, which is easier to assemble.
Diese Aufgabe wird erfindungsgemäß mit einer Formkernanordnung gelöst, die die Merkmale des Anspruchs 1 aufweist. Der Vorteil dieser Anordnung besteht darin, dass die beiden schalenförmigen, die Zylinderkerne jeweils seitlich überdeckenden Wassermantelteilkerne wie üblich mit dem Sohlenkern verbunden werden können, jedoch gegeneinander durch das metallische Verbindungselement fixiert sind. Beim Abgießen wird der verbleibende, nur vom metallischen Verbindungselement überbrückte stirnseitige Zwischenraum zwischen den beiden Wassermantelteilkernen von der Metallschmelze, beispielsweise einer Graugußschmelze ausgefüllt. Mit Abschluß des Gießvorganges sind die aus Metallblech, beispielsweise aus Eisenblech hergestellten Verbindungselemente aufgeschmolzen, so dass die Verbindung zwischen den beiden Wassermantelteilkernen unterbrochen ist und die Formmassen der Wassermantelteilkerne ebenso wie die Formmassen der Zylinderkerne und des Sohlenkerns in üblicher Weise aus dem Gussstück entfernt werden können.This object is achieved with a mold core assembly having the features of claim 1. The advantage of this arrangement is that the two shell-shaped, the cylinder cores each laterally covering water jacket dividing cores can be connected as usual with the sole core, but are fixed against each other by the metallic connecting element. When pouring the remaining, bridged only by the metallic connecting element frontal space between the two Wassermantelteilkernen of the molten metal, such as a gray cast melt is filled. With the completion of the casting process are made of sheet metal, such as sheet iron Melted connecting elements, so that the connection between the two water jacket core parts is interrupted and the molding compositions of the water jacket dividing cores as well as the molding compounds of the cylinder cores and the sole core can be removed in a conventional manner from the casting.
Der besondere Vorteil der Erfindung besteht darin, daß bei der Herstellung der beiden Wassermantelteilkerne die Verbindungselemente in die Kernform eingelegt und beim Einschießen der Kernformmasse eingebunden werden, so daß nach dem Aushärten der Kernformmasse dieser aus zwei Teilkernen bestehende Kern wie eine Einheit gehandhabt und mit dem die Zylinderkerne aufweisenden Sohlenkern zu einer vollständigen Kernanordnung zusammengefügt werden kann.The particular advantage of the invention is that in the manufacture of the two water jacket cores, the fasteners are inserted into the core mold and involved in shooting the core molding compound, so that after curing of the core molding compound of this core consisting of two partial cores handled as a unit and with the Cylinder core having sole core can be assembled into a complete core assembly.
Die Erfindung wird anhand einer schematischen Zeichnung eines Ausführungsbeispieles näher erläutert.The invention will be explained in more detail with reference to a schematic drawing of an embodiment.
Die Zeichnung zeigt eine Formkernanordnung für eine Zylinderbank mit beispielsweise vier Zylindern in Reihenanordnung mit geteiltem Wassermantel. Wie die Zeichnung erkennen lässt, besteht die Formkernanordnung aus vier Zylinderkernen 1,2,3 und 4, die mit einem Sohlenkern 5 einstückig aus Kernformmasse geformt werden. Die Kernformmasse wird hierzu in einer Kernformmaschine in üblicher Weise in eine die Zylinderkerne 1 bis 4 und den Sohlenkern 5 umschließende Kernform eingeschossen.The drawing shows a mold core arrangement for a cylinder bank with, for example, four cylinders in a series arrangement with a split water jacket. As can be seen from the drawing, the mold core assembly consists of four
Den Zylinderkernen 1 bis 4 sind zwei Wassermantelteilkerne 6.1 und 6.2 zugeordnet, die schalenförmig die Reihe der Zylinderkerne 1 bis 4 an den Längsseiten mit Abstand überdekken. Die beiden Wassermantelteilkerne 6.1 und 6.2 sind hierbei so gestaltet, dass jeweils stirnseitig ein Freiraum 7 verbleibt.The cylinder cores 1 to 4 are associated with two water jacket partial cores 6.1 and 6.2, the cup-shaped over the row of cylinder cores 1 to 4 on the longitudinal sides at a distance over. The two water jacket partial cores 6.1 and 6.2 are in this case designed so that in each case a
Die beiden Wassermantelteile 6.1 und 6.2 werden durch Einlegen eines Verbindungselementes 8 aus Metallblech in die Formgebungskonturen der Kernschießmaschine zusammen in einem Schritt, d. h. in einem Kernschießprozeß, hergestellt. Durch das eingeschlossene Verbindungselement 8 sind die beiden Wassermentalteilkerne 6.1 und 6.2 fertigungstechnisch praktisch in gleicher Weise nutzbar, wie sonst übliche einteilige Wassermantelkerne.The two water jacket parts 6.1 and 6.2 are made by inserting a connecting element 8 made of sheet metal in the shaping contours of the core shooter together in one step, d. H. in a nuclear shooting process, manufactured. Due to the enclosed connecting element 8, the two Wassermentalteilkerne 6.1 and 6.2 manufacturing technology practically in the same way usable as usual one-piece water jacket cores.
Die beiden Wassermantelteilkerne sind somit stirnseitig über das Verbindungselement 8, beispielsweise aus Eisenblech, fest miteinander verbunden, so dass die beiden Wassermantelteilkerne 6.1 und 6.2 als starre Einheit gehandhabt und mit dem Sohlenkern 5 zusammengefügt werden können. Hierzu sind, wie üblich, jeweils an der unteren Randseite 9 beider Wassermantelteilkerne 6.1 und 6.2 zapfenförmige Vorsprünge geformt, denen entsprechende Vertiefungen auf der Formfläche 10 des Sohlenkerns 5 zugeordnet sind. Über die mit Abstand zur Formfläche 10 des Sohlenkerns 5 vorgesehenen Verbindungselemente 8 sind die beiden Wassermantelteilkerne 6.1 und 6.2 gegeneinander fixiert, so dass sie beim Gießvorgang die vorgegebene Position zueinander und zu den Zylinderkernen 1 bis 4 beibehalten.The two water jacket dividing cores are thus connected to one another at the ends via the connecting element 8, for example made of sheet iron, so that the two water jacket dividing cores 6.1 and 6.2 can be handled as a rigid unit and joined together with the sole core 5. For this purpose, as usual, each formed on the lower edge side 9 of both water jacket dividing cores 6.1 and 6.2 peg-shaped projections, which corresponding depressions on the
Durch die beim Abgießen in die fertige Gießform einlaufende Schmelze werden die im Bereich der stirnseitigen Öffnung 7 freiliegende Teile der Verbindungselemente 8 vollständig aufgeschmolzen bzw. verschmolzen, so daß mit der Erstarrung der Schmelze zwischen den beiden Wassermantelteilkernen 6.1, 6.2 keine feste Verbindung mehr besteht. Die aus Eisenblech bestehenden Verbindungselemente 8 werden in ihrer Blechstärke so bemessen, dass ein vollständiges Aufschmelzen zum Ende des Gießvorganges gewährleistet ist. Damit ist auch gewährleistet, dass die Wassermantelteilkerne ihre Position in der Gießform während des Zulaufs der Schmelze nicht verändern. Zugleich ist auch gewährleistet, dass nach dem Abguss und dem Entfernen des Kernformmaterials aus dem Gußstück eine ungestörte Durchströmung des Kühlmittels durch die beiden Wassermantelteile gewährleistet ist.As a result of the melt entering the finished casting mold during casting, the parts of the connecting elements 8 which are exposed in the area of the
