Problems solved by technology

Irrespective of whether it is built integrally with the base plate itself or has an insert as in the above publication, there are disadvantages due to the system, namely, since this is a permanent mold, the design freedom is limited by the necessity of draft angles

Embodiment Construction

[0029] figure 1 A core comprising a plurality of second forming segments 20 , which are connected by connecting rods 22 , is shown in plan view. The reference L designates the longitudinal axis, which can also be regarded as the axis of rotation of the crankshaft. Shown schematically now is a projection 24 that extends, so to speak, along the longitudinal axis L and is designed to form a material recess in a bearing seat or a bearing channel of a crankcase.

[0030] figure 2 basically shown by figure 1 Known embodiments of the core, in the embodiment shown here, the second forming section 20 has no protrusions. Here, however, a side view of the core is shown in the upper half of the figure, in which it can be seen how the second forming sections 20 are connected by connecting rods 22 .

[0031] image 3 A schematic view of an ingot mold comprising a metal substrate 10 comprising a first forming section 12 is shown. The longitudinal axis L is oriented approximately perpe...

Abstract

The invention relates to an ingot mold comprising a base made of metal. The base has a plurality of first mold portions which are mutually spaced along a longitudinal axis and are designed to shape abearing tunnel of a crankcase, and second mold portions arranged on the first mold portions and consisting of a mold material.

Description

technical field [0001] The present invention relates to an ingot mold and method for manufacturing crankcases of internal combustion engines. Background technique [0002] Ingot molds are reusable molds for casting metals and alloys. In particular, cylinder crankcases of internal combustion engines are often manufactured using the ingot casting method. Such ingot molds generally comprise a metal base plate and corresponding end or side slides which, inter alia, shape the shape of the subsequently cast part. In addition, cores can also be used to realize cavities and the like. Metal substrates are often used to form the crank chambers of cylinder crankcases. In this case, DE 10 2006 061 653 A1, for example, shows an insert dedicated to a base plate which shapes or at least co-forms the crank chamber of the cast part. Irrespective of whether it is constructed integrally with the base plate itself or has an insert as in the above publication, there are disadvantages due to ...
