- the casting cores are formed from a molding material, which is typically a molding sand-binder mixture, which is introduced (“shot”) at high pressure into the shaping cavity of the core shooting device.
- a molding material typically a molding sand-binder mixture, which is introduced (“shot”) at high pressure into the shaping cavity of the core shooting device.
- Form cavity of the provided for producing the cores machine is introduced, are tuned so that a complete
- Mold filling is achieved even with very finely divided cores.
- the cores are solidified by application of heat or gassing with a reaction gas so that they can be used in the respective mold and withstand the loads occurring during the casting of the respective molten metal loads.
- the invention relates to a device for shooting a
- Casting core which encloses a free interior space at its outer boundaries, wherein the device has a mold cavity forming the mold cavity, which extends about a longitudinal axis along a longitudinal axis
- Inner slide circulates and on its outside by one around the
- Mold cavity circulating outer slide is limited, the light Width of the mold cavity by the distance of the mold cavity associated inner surface of the outer slide to the outer surface of the
- Casting cores of the type to be produced by means of a device according to the invention are thus distinguished by the fact that they delimit, in the manner of a hollow cylinder, an inner space around which they are guided in an annular manner.
- the particular challenge in the production is that the cores usually do not represent pipes with a solid wall, but that their wall bounding the interior is often broken or provided with recesses, in addition locally vary in size material accumulations may be present over finely branched webs, bridges or other filigree shaped mold elements are interconnected.
- the inner slider is attached to a lid and has a
- the outer slide is in a through the centrally arranged longitudinal axis of the outer slide
- the object was to provide a device which enables the reliable production of tubular in their basic form, but in their walls finely structured casting cores also on a large scale.
- the invention has achieved this object by the device specified in claim 1.
- a device according to the invention for shooting a casting core which encloses a free interior space at its outer boundaries, accordingly has a mold cavity forming the casting core, which rotates about an inner slide extending along a longitudinal axis and is delimited on its outer side by an outer slide circulating around the mold cavity , wherein the clear width of the mold cavity is determined by the distance of the mold cavity associated inner surface of the outer slide to the outer surface of the inner slide.

- Longitudinal axis of the inner slide are positioned approximately and existing between the inner slide and the outer slide clearance of the mold cavity is increased in an outer slide approximate shot position are adjustable, in which the clear width of the mold cavity corresponds to a target specification for the casting core to be shot.
- the inner slide is thus divided into two or more segments which are positioned between a removal position in which they are closely adjacent to each other, and a
- Inner slide segments are separated from each other in firing position by a gap.
- this proves to be uncritical in practice because it is easily possible in most applications, the course of the dividing planes between the adjacent to each other
- the dividing planes generally run in the longitudinal direction of the inner slide. That is, the inner slide segments are longitudinal and not divided transversely to the longitudinal direction of the inner slide. Of course, this does not exclude the division levels
- sections also extend in the transverse direction of the longitudinal direction, for example, in the circumferential direction of the inner slide projecting or recessed heels on the inner slide segments. It is crucial that the inner slide segments can be moved apart by a directed in the direction of the central longitudinal axis of the inner slide movement toward and away from a directed by the central longitudinal axis movement.
