Die Erfindung betrifft eine Giessform zur Herstellung einteiliger Uhrgehäuse, bei denen die oberen Mittelteilglasreifen von Modell zu Modell unterschiedlich gestaltet, die unteren Mittelteilglasreifen und Böden bei allen Modellen jedoch gleich ausgebildet sind.The invention relates to a casting mold for the production of one-piece watch cases, in which the upper middle part glass hoops from model The lower middle section glass hoops are designed differently from the model and bottoms are the same for all models.
Bei einer derartigen Herstellung einteiliger Uhrgehäuse ist es bekannt, für jede Gehäuseform, die man zu erhalten wünscht, eine besondere Giessform zu verwenden. Bei Gehäusen desselben Kalibers, die man wegen der geringen Herstellungskosten durch Giessen herstellt, ist es allgemein üblich, dass der untere Teil des Mittelteilglasreifs und der Boden dieselbe Form aufweisen, während nur der obere Teil des Mittelteilglasreifs anders gestaltet wird, um derartigen Uhren mit weiter Verbreitung ein unterschiedliches Aussehen zu geben. Jedes Modell muss daher mittels einer anderen Form hergestellt werden, deren Wert und Herstellungskosten verhältnismässig hoch sind.In such a production of one-piece watch cases, it is known to use a special mold for each housing shape that one wishes to obtain. For cases of the same caliber, which are produced by casting because of the low production costs, it is common practice that the lower part of the central part bezel and the bottom have the same shape, while only the upper part of the middle part bezel is designed differently in order to give such wide-spread watches a different appearance. Each The model must therefore be made using a different form, the value and cost of which are relatively high.
Zur Vermeidung dieses Nachteiles ist eine Giessform der vorstehend beschriebenen Art erfindungsgemäss gekennzeichnet durch einen einzigen Formunterteil zur Formung des Gehäusebodens samt unteremTo avoid this disadvantage, a mold is the one above described type according to the invention characterized by a single lower mold part for shaping the housing bottom including the lower

Mittelteilglasreif und durch mehrere auswechselbare Formoberteile, welche zur unterschiedlichen Gestaltung der oberen Mittelteilglasreifen mit verschieden ausgebildeten Formflächen versehen sind«Middle part glass ring and several interchangeable upper parts, which for the different design of the upper middle section glass hoops are provided with differently designed shaped surfaces «
Dabei können die Anlageflächen, womit die beiden Formteile aneinanderliegen, konkav, konvex oder gewinkelt mit flachen oder geneigten Rändern ausgebildet sein.The contact surfaces, with which the two molded parts lie against one another, can concave, convex or angled with flat or sloping edges.
Der wesentliche Vorteil einer solchen zweiteiligen Ausbildung der Giessform besteht vor allem in der erheblichen Herabsetzung der Herstellungskosten für verschiedene Formen, die alle den gleichen Unterteil haben.The main advantage of such a two-part design of the casting mold consists primarily in the considerable reduction in the Manufacturing costs for different shapes that all have the same base.
Ein weiterer Vorteil besteht in den zahlreichen Gestaltungsmöglichkeiten von Uhrgehäusen, deren Oberteil verschiedene Formen aufweisen und beispielsweise auch exzentrisch zum Unterteil angeordnet sein können, ohne hierfür jeweils eine besondere Giessform zu benötigen. Another advantage is the numerous design options of watch cases, the upper part of which has different shapes and, for example, also arranged eccentrically to the lower part can be without each needing a special mold for this.
Ih der beigefügten Zeichnung sind beispielsweise Aus führung s möglichkeiten einer erfindungsgemässen Giessform in Schnitten dargestellt, wobei zeigen:Ih the attached drawing are examples of possible designs a mold according to the invention shown in sections, showing:

Danach besteht die erfindungsgemässe Giessform aus einem einzigen, unveränderlichen Formunterteil 1, welcher den Boden 4 des Uhrgehäuses bis zur Höhe der Verbindungsebene 3 zwischen den beiden Formteilen formt, und aus einem Formoberteil 2, welcher die äussere Gestaltung und das Aussehen des Mitteiteilglasreifs 5 bestimmt. DieserThereafter, the mold according to the invention consists of a single, unchangeable lower mold part 1, which is the bottom 4 of the watch case up to the level of the connecting plane 3 between the two molded parts forms, and from an upper mold part 2, which the external design and the appearance of the middle part glass hoop 5 is determined.
