Abstract

The mould cast (1) comprises two halves (1a,1b) and is divided in a division plane (X-X). In each of the two mould box halves, the pattern of the disc mould body to be produced is moulded after the introduction of mould sand (5) in the mould box halves with the formation of a corresponding cast hollow space cavity. The hollow spaces, formed in the cast body, are closed by cores set in the mould box. In the mould box (1) are an outer core and an inner core (3). After bringing the mould halves together, the hollow space of the mould is formed and is filled with metal smelt, esp. cast iron, for prodn. of the disc mould body (4). The pattern is moulded only with an inner core.

Description

Die Erfindung betrifft ein Verfahren zur Vorbereitung einer mittengeteilten Form für den Abguß eines Scheibenformkörpers, insbesondere einer Bremsscheibe, bei dem der Formhohlraum von der Teilungsebene der Form aus in beide Formhälften hinein ausgeformt wird. Nach dem Einsetzen des Modells werden die Formhälften mit Formsand gefüllt. Das Modell des Scheibenformkörpers ist dabei etwa je zur Hälfte in jeder der beiden Formhälften abgeformt. Danach wird das Modell entfernt, und die Formhälften werden unter Bildung des Formhohlraums zusammengesetzt.The invention relates to a method for preparation a split mold for casting one Disc shaped body, in particular a brake disc the mold cavity from the parting plane of the mold is molded into both mold halves. After this The mold halves are inserted with molding sand filled. The model of the molded disk is included about half each in each of the two mold halves molded. Then the model is removed and the Mold halves are formed to form the mold cavity composed.

Beim Abguß von scheibenförmigen Körpern, nachfolgend "Scheibenformkörper" genannt, war es bisher üblich, das Modell des Scheibenformkörpers so in den Formkasten einzusetzen, daß die Scheibengroßfläche parallel zur Teilungsebene der Form liegt.When casting disc-shaped bodies, below Called "disc shaped body", it was previously common that Model of the molded disc body in the molding box insert that the large pane parallel to Partition level of the form lies.

Der Erfindung liegt nun die Aufgabe zugrunde, die Produktionskosten von gegossenen Scheibenformkörpern zu senken.The invention is based on the object Production costs of cast disc moldings too reduce.

Dies gelingt, wenn bei dem gattungsgemäßen Verfahren erfindungsgemäß zur Ausbildung des Formhohlraums das Modell des Scheibenformkörpers mit in einer zur Teilungsebene der Form senkrechten Ebene stehenden Scheibenflächen abgeformt wird. This succeeds when using the generic method according to the invention to form the mold cavity Model of the shaped disc body with in a Partition plane of the form vertical plane standing Is molded from the disk surfaces.  

Die Vorteile bei Ausführung des erfindungsgemäßen Verfahrens bestehen zum einen darin, daß man auf einer gleich großen Stellfläche die doppelte Menge Gußkörper abgießen kann. Ferner kann die Abgußzeit erheblich verkürzt werden, weil die in einer Form befindlichen zwei oder mehr Gußkörper nahezu gleichzeitig erzeugt werden können. Ein weiterer Vorteil des erfindungsgemäßen Verfahrens ist, daß man auf einen Kern, nämlich den Außenkern, wegen der anderen Lage des Modells beim Abformen des Formhohlraums in der Form verzichten kann, der bislang für die hinterschnittenen Abschnitte des Scheibenformkörpers notwendig war. Solche Abschnitte sind nun entfallen.The advantages in executing the invention On the one hand, the procedure consists in the fact that on a double the amount of cast body can pour. Furthermore, the casting time can be significant be shortened because the two are in the same shape or more castings are produced almost simultaneously can. Another advantage of the invention The procedure is to focus on one core, namely the Outer core, because of the different position of the model at Can do without molding of the mold cavity in the mold, the so far for the undercut sections of the Washer shaped body was necessary. Such sections are now dropped.

Diese Vorteile summieren sich zu einer erheblichen Verminderung der Produktionskosten, ohne daß hierzu ein besonderer Aufwand erforderlich ist. Die Vorteile lassen sich vielmehr mit den gleichen Mitteln erreichen, die man bisher schon beim Formgießen verwendet hat.These advantages add up to a significant one Reduction of production costs without this special effort is required. Let the advantages rather, reach yourself with the same means that one previously used in die casting.

Anhand der Zeichnung wird die Erfindung näher erläutert.The invention is explained in more detail with reference to the drawing.

Gleiche Teile sind in den verschiedenen Abbildungen mit denselben Bezugszeichen versehen.The same parts are in the different illustrations provided the same reference numerals.

Der Formkasten 1 besteht aus den Formhälften 1a und 1b. Er ist jeweils in der Teilungsebene X-X mittengeteilt. In jeder der beiden Formkastenhälften 1a und 1b ist das Modell des zu erzeugenden Scheibenformkörpers nach dem Einbringen des Formsandes 5 in die Formkastenhälften unter Bildung einer entsprechenden Gießhohlraumvertiefung abgeformt. Die Hohlräume, die im Gußkörper gebildet werden sollen, sind durch in den Formkasten 1 eingesetzte Kerne geschlossen. Bei der herkömmlichen Gießweise befindet sich im Formkasten 1 ein Außenkern 2 und ein Innenkern 3. Nach dem Zusammensetzen der Formhälften 1a, 1b wird der Formhohlraum gebildet. Dieser wird zur Erzeugung des Scheibenformkörpers 4 mit Metallschmelze, insbesondere Gußeisen, ausgefüllt.The molding box 1 consists of the mold halves 1 a and 1 b. It is divided in the middle in division level XX. In each of the two mold box halves 1 a and 1 b, the model of the disk moldings to be produced is molded after the molding sand 5 has been introduced into the mold box halves to form a corresponding casting cavity recess. The cavities that are to be formed in the cast body are closed by cores inserted into the molding box 1 . In the conventional casting method, there is an outer core 2 and an inner core 3 in the molding box 1 . After assembling the mold halves 1 a, 1 b, the mold cavity is formed. This is filled with molten metal, in particular cast iron, to produce the shaped pane body 4 .

Bei der bisherigen Ausführung gemäß Fig. 1 und 2 wird der Scheibenformkörper 4 mit parallel zur Teilungsebene X-X liegender Scheibe 4a abgegossen. In dem Formkasten 1 nach Fig. 3 und 4 sind dagegen zwei Gußkörper mit senkrecht zur Teilungsebene X-X der Form 1 sich erstreckender Scheibe 4a abgegossen.In the previous embodiment of FIGS. 1 and 2 of the disc shaped body 4 lying parallel to the parting plane XX disc 4 a is decanted. In contrast, in the molding box 1 according to FIGS. 3 and 4, two cast bodies with a disc 4 a extending perpendicular to the parting plane XX of the mold 1 are cast.

Für den Abguß benötigt man jeweils nur einen Innenkern 3. Beim Abguß nach dem in Fig. 1 und 2 dargestellten bekannten Muster war demgegenüber wie gesagt noch ein zusätzlicher Außenkern 2 erforderlich. Dieser kann nach dem neuen Verfahren entfallen, weil keine Hinterschneidungen auftreten, die durch einen Außenkern abgedeckt sein müssen.Only one inner core 3 is required for the casting. In contrast, when casting according to the known pattern shown in FIGS. 1 and 2, an additional outer core 2 was required. This can be omitted according to the new method because there are no undercuts that have to be covered by an outer core.
