- the tubular element 22 of the feeder insert 8 according to the invention is inserted maximally far into the adapter element 24.
- the illustration includes two cutting planes through the adapter element 24: on the left side of the axis of rotation 48 in FIG. 2, the cutting plane is selected such that the travel limiter 26 is not cut (section A), on the right side of the rotation axis 48 in FIG the cutting plane passes through the Wegbeskyr 26 (section B, to select the cutting planes see also Fig. 4).

- the connecting surfaces between the holding projections 34 and the adapter element 24 are each quite small, so that the holding projections 34 can be separated from the adapter element 24 with little effort.
- the upper feeder part 18 Due to the force resulting from the compression, the upper feeder part 18 is displaced in the direction of the mold model 12. In this case, the force need only be sufficiently large to hold the retaining projections 34 from the adapter element 24 to separate.
- the displacement path of the upper feeder part 18 in the direction of the mold model 12 is predetermined and limited by the degree of compression molding.

It can again be seen that the outer surface 46 of the edge region 46 of the tubular element 22 opposite the first end 14 is free in sections of the circumference.
- the cavity 44 of the adapter member 24 includes the free portions of the outer surface 46 of the first end 14 opposite edge region of the tubular member 22 at maximum insertion, so that liquid metal during the casting process with the outer surface 46 of the tube-like element 22 contact and contact there can remain. After solidification of the metal is achieved so that the feeder insert 8 breaks off during cleaning in the immediate vicinity of the casting and not in the upper region of the outer surface 46 of the tubular member 22.
- the tube-like element 22 can already be completely inserted into the adapter element 24 prior to compaction (compare FIG. 2).

- a slot of at least 4 mm is ensured, see. Fig. 1.
- the compression forces occurring during the compression of the molding material are counteracted by two separate relative movements: first, by the relative movement between the upper feeder part 18 relative to the adapter element 24 and, secondly, by the relative movement between the adapter element 24 and the tubular element 22.
- FIGS. 1-3 also schematically illustrate a method according to the invention for arranging a feeder insert according to the invention in a casting mold.
- a tube-like element 22 which is inserted into an adapter element 24, placed together with this on a centering mandrel 36 which is mounted on a mold model 12.
- the tubular element 22 is thereby brought into direct contact with the mold model 12 with a first end 14.
- the tubular member is only partially, i. not maximally inserted far into the adapter element 24.
- the tubular element 22 can be inserted maximally far into the adapter element 24, cf. Fig. 2.
- an upper feeder part is placed on the adapter element 24 so that it is supported by this.
- holding projections 34 are provided, for example.
- the feeder insert 8 is enveloped with molding sand 32 or another molding material (cladding indicated only in the lower region).
- the tube-like element 22 is inserted maximally far into the adapter element 24, so that it rests against travel limiters 26 and can no longer be pushed into the adapter element 24. Whether the tubular element 22 partially or maximally in the adapter element 24 before the Compression process is inserted depends on the particular application.
- the arrangement according to FIG. 3 results.
- the holding projections 34 are broken off by the adapter element 24, the upper feeder part 18 is pushed telescopically a distance onto the adapter element 24.
