- Cooling element enables:
- the removal device comprises a means for gripping a removal projection attached to the at least one cooling element.
- the removal device is preferably designed to be movable in order to remove the at least one cooling element from a cast part arranged in a stationary manner. It is also conceivable that a removal device is arranged in a stationary manner and a cast part for removing the cooling element is moved relative to a removal device. A manual removal of the cooling elements is advantageously not necessary. Furthermore, centering can advantageously be brought about by the removal device, which enables the at least one removed cooling element to be always positioned in the same way. This enables automated storage in a storage pallet for reuse.
- Cooling channels have a particularly low porosity in order to prevent loss of coolant
- a mold core which can be a sand or salt core, for example, into a casting mold with which a casting is made.
- the casting mold can be a permanent mold such as a permanent mold or a one-time mold
- the removal projection is formed in one piece on the cooling element, connected to it in a materially bonded manner, or releasably connectable to the cooling element.
- the cooling element is preferably made of gray cast iron or a steel, in particular one
- a cooling element has several removal projections. Should one of the removal projections be damaged, another can advantageously be used to remove the cooling element from the cast part. An immediate exchange is not necessary.
- a one-piece molding advantageously enables simple production, while an integral connection enables a damaged removal projection to be replaced or repaired by welding and soldering.
- the gripping means expediently comprises at least one pair of rails which are spaced apart from one another and which are set up to engage behind the removal projection.
- the removal projection can advantageously be gripped by a pair of rails in such a way that only removal forces are transmitted which preferably act perpendicularly or almost perpendicularly to a longitudinal direction of the rails.
- the removal projection of the at least one cooling element comprises at least a pair of spaced apart rails which are designed to be gripped from behind by the gripping means. That is advantageous
- Removal device structurally simplified and thereby enables longer service life.
- the gripping means has a plurality of pairs of rails which, in the circumferential direction, are essentially rotationally symmetrical, preferably
- cylindrical or frustoconical removal head are arranged side by side and in particular extend parallel or obliquely to its longitudinal axis.
- a plurality of cooling elements can advantageously be removed at the same time in a single work step and centered by the removal head when they are removed.
- the cooling elements are introduced into an essentially reddening-symmetrical, preferably cylindrical or frustoconical mold core of a casting mold, which forms a cavity for receiving the rotor or a rotor carrier of the electric motor.
- cooling elements which preferably form flush surface sections of a mold core and are in contact with a melt when a casting mold is filled, each has a surface whose outer contour is almost identical to a functional inner contour section of a cavity of a casting from which the
- Cooling element is removable. A near-net shape production of a cast part is advantageously possible.
- a particularly good fixation of the cooling elements in the mold core and their particularly good gripping ability when they are removed from the cast part are achieved when a
- Removal projection is arranged on one side of a cooling element that faces away from a side that is in contact with the melt when a casting mold is being filled.
- the removal projection on the one hand can form a latching connection with the mold core and can also be gripped by the gripping means.
- a mold core which is particularly suitable for the method according to the invention can be designed in one piece or in several parts, in particular in two parts. There is advantageously a particularly high degree of design freedom.
- the at least one cooling element can be introduced into the mold core in such a way that a plurality of surface sections are formed, at least one of which is formed by an outer side of the cooling element, it can be introduced before Molding sand are placed in a molding core production tool.
- a stationary arrangement in the mold core production tool can be brought about by the removal projection, which for this purpose engages in a holding device in the tool.
- the removal projection advantageously acts for fixing in the mold core production tool and as a counter-holder for a gripping means of a device for removing at least one cooling element from an at least partially sanded cast part.
- each pair of rails can engage behind an associated removal projection when the removal head moves in a straight line into the cavity.
- Several cooling elements can advantageously be removed in one work step. The centering of the
- each of the rails is detachable with an essentially rotationally symmetrical, preferably cylindrical or frustoconical one
- Removal head of the removal device or connectable to the at least one cooling element Removal head of the removal device or connectable to the at least one cooling element. Damaged rails are advantageously easy to replace. Maintenance and / or repair work is reduced.
- a diameter of an essentially frustoconical removal head of the removal device increases in a direction in which the removal head enters a casting cavity for removal of
- Cooling elements is movable, and which is preferably coaxial to a longitudinal direction of the removal head. This enlargement causes the formation of a draft angle, which ensures that the forces required to remove cooling elements from a cast part are applied in a linearly increasing manner. Voltage peaks, which could damage the removal head, are advantageously avoided.
- a removal projection of a cooling element has a T-shaped cross section and preferably extends into a longitudinal direction of the cooling iron.
- T-legs can advantageously be gripped or gripped from behind by the gripping means, in particular by a pair of rails, in such a way that no transverse forces or bending moments occur which could damage the
- the thickness of the T-legs increases, preferably linearly, from a first end to a second end, in particular in the longitudinal direction of a cooling element
- a linear movement of a removal head or that of the cast part relative to a stationary removal head with a gripping means that is a Has a pair of rails for engaging behind the T-legs are converted into a movement of the cooling elements with a movement component perpendicular to the direction of movement of the removal head.
- a detachment of cooling elements from the cast part is advantageously effected.
- a linear movement of the cast part or the removal head can also advantageously be converted into a differently directed movement of the at least one cooling element.
- Rails which are preferably flat and have a constant thickness, slide along the T-legs for this purpose.
- the removal head also has a draft angle, for example between 2 and 5 degrees, preferably 4 degrees, a particularly short path is required in combination with T-legs of varying thickness during a removal movement in order to apply a sufficiently large force to the at least one cooling element to detach from the cast part, to center it and finally to remove it from one
- Cast part wall section formed, which rests with one side against the at least one cooling element during a cast part production and which has a secondary dendrite arm spacing between 3 and 30 m, preferably between 15 and 25 ⁇ m. Particularly high strength with low porosity is advantageously achieved. A low porosity is necessary in particular when the cast part wall section delimits a cooling channel in which a liquid cooling medium is guided during engine operation.
- a cast part comprises a groove which is provided for receiving a sealing ring, pores have a maximum diameter of 0.9 mm, preferably between 0.5 and 0.8 mm.
- a particularly dense cast part can advantageously be produced. Loss of coolant during engine operation is prevented.

- the surface (14) is also provided to come into contact with a metal melt with which a casting mold is filled. This results in a particularly good casting quality, in particular high strength and low porosity in a casting area adjoining the cooling iron (2a). This can, for example, extend up to 25 mm from the cooling iron (2a) and have a porosity with pores with a Feret diameter of a maximum of 0.8 mm.
- a first projection (16) is integrally formed on a first end face (15), while two further projections (18, 19) are integrally formed on a second end face (17).
- Projections (16, 19) are provided to be engaged from behind by a mold core into which the cooling iron (2b) is inserted. This achieves both a fixation in the mold core and a flush termination of a surface of the mold core with the curved surface (14) of the cooling iron (2a).
