Ingot Mold and Method for Producing a Component

Abstract

A mold includes an ingot mold and a top core. The top core is disposed in and/or on the ingot mold. The top core forms, in part, a functional surface of a component formed in the mold and the ingot mold forms at least a sub-region of the functional surface of the component formed in the mold.

Claims

1. A mold, comprising: an ingot mold; and a top core, wherein the top core is disposed in and/or on the ingot mold, wherein the top core forms, in part, a functional surface of a component formed in the mold, and wherein the ingot mold forms at least a sub-region of the functional surface of the component formed in the mold.

2. The mold according to claim 1, wherein the functional surface is a cover flange and wherein the component is a cylinder head.

3. The mold according to claim 1, wherein the ingot mold includes two molding parts which are displaceable laterally in a direction of the top core.

4. The mold according to claim 3, wherein the two molding parts are pivotable.

5. The mold according to claim 3, wherein, for a purpose of forming the functional surface, the top core and the two molding parts have respective molding surfaces which merge one inside the other without any offset.

6. The mold according to claim 1, wherein a length of the top core corresponds to a length of the component along a longitudinal direction of the component.

7. The mold according to claim 1, wherein the top core has a plurality of cylindrical feeders.

8. The mold according to claim 7, wherein the plurality of cylindrical feeders are disposed one after the other along a longitudinal direction of the component.

9. The mold according to claim 1, wherein the top core has a first molding element which forms a first bearing location in the functional surface.

10. The mold according to claim 9, wherein the first bearing location is a first bearing tunnel, wherein the functional surface is a cover flange, and wherein the component is a cylinder head.

11. The mold according to claim 3, wherein at least one of the two molding parts has a second molding element which forms a second bearing location in the functional surface.

12. The mold according to claim 11, wherein the second bearing location is a second bearing tunnel, wherein the functional surface is a cover flange, and wherein the component is a cylinder head.

13. A method for producing a component, comprising the acts of: supplying an ingot mold and a top core; and forming a functional surface of the component by the top core and at least partially by the ingot mold.

14. The method according to claim 13, wherein the component is a cylinder head.

15. A use of the mold according to claim 1 in a production of a motor vehicle.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0023] FIG. 1 shows a perspective view of an ingot mold along with a casting;

[0024] FIG. 2 shows a sectional illustration of the ingot mold from FIG. 1 along with the casting; and

[0025] FIG. 3 shows a perspective view of a casting.

DETAILED DESCRIPTION OF THE DRAWINGS

[0026] FIG. 1 shows a perspective view of an ingot mold (illustrated only to some extent) comprising two molding parts 22, in or on which two swing-action or pivotable molding parts 20 are mounted or positioned. Arranged between the latter molding parts is a top core 40, which has a multiplicity of feeders 42 arranged along a longitudinal direction L of a component, in this case, in particular, of a cylinder head 60. The mold, or ingot mold, is filled with casting material 70. It can be seen that the top core 40 and the pivotable molding parts 20 have molding surfaces 30, which form a common functional surface (cf. reference sign 62 in FIG. 2). The size, in particular the width, of the top core 40 is limited, so to speak, to a minimum.

[0027] FIG. 2 shows a sectional illustration of the ingot mold which is known essentially from FIG. 1. The movement capability of the pivotable molding parts 20 is illustrated by way of the double arrows on the molding parts. It can be seen that the top core 40 has a protrusion 46, which forms a corresponding geometry in a subsequent casting. In addition, the top core 40 and the pivotable molding parts 20 have molding elements 24 and 44, which form a bearing tunnel 64 in the cylinder head 60, cf., in this respect, in particular also FIG. 3.

[0028] FIG. 3 shows the definitively cast and demolded cylinder head 60, it being possible to see, in particular, the functional surface 62 or the cover flange 62. In addition, the bearing tunnel 64, which serves to hold a camshaft, can be seen to good effect. It is clear, in particular, that the feeder volume is very small, and the ingot mold and the method provide for solidification which is optimally directed towards the feeders.
