Definitions
- the invention relates to a method for casting of components made of light metal, preferably from Al alloys, according to the Kippg discernkar and a device for carrying out the method.
- a preferred field of application of the invention is the casting of aluminum cylinder heads and engine blocks.
- tilt casting is a well-known method.
- Kippgie As a particular advantage 10 of Kippgie calls is found in the literature that the case of gravity casting possibly occurring splashing of the metal by passing the molten metal at a wall of the mold can be avoided (R Schneider, molds for light metal casting, foundry A / sued 1986, p 100 ff ).
- the casting mold is arranged with the gate downwards above a casting container and, after filling the casting container, gas-tightly connected to a quantity of melt sized for casting, so that the melt rotates by 180 ° into the mold cavity during rotation of the casting mold and casting container flows.
- the gate runs along the longitudinal axis of the casting mold in order to ensure that the inflow of the melt takes place over the largest possible cross section 30 of the gate in the ratio of the cross section of the die cavity.
- the high technical complexity relates to a rotatable by 180 ° casting device with a separate; airtight with the mold to verbin ⁇ dender tundish and on the other hand, the mold in which in complex castings unavoidable cores must be installed so firmly that they remain fixed in position stable even with a rotation of the mold by 180 °.
- the object of the present invention is to develop a method and apparatus for carrying out the casting process more complicated; high-quality components made of light metal, preferably of Al alloys, with which the disadvantages of the prior art are overcome.
- a casting mold with an upwardly pointing sprue, on the longitudinal side of which a cross run connected to the sprue through outlets is arranged is tilted at 45 ° to 70 ° about its longitudinal axis.
- the cross-section is dimensioned with respect to its volume and with respect to the arrangement of the outlets to the mold cavity designed so that at 45 ° to 70 ° about its longitudinal axis tilted mold with cross-section in a second process step about 1/5 of the required melt for the melt in the cross-flow can be filled without the melt already flowing into the mold cavity of the mold.
- the casting mold is tilted back into the cross-section up to the vertical, with continuous further filling of melt, the melt flowing in via the outlets into the mold cavity.
- the outlets of the cross-flow to the mold cavity should be arranged and designed so that the melt, as usual in Kippgie health, flows along a side wall of the mold into the mold cavity.
- the casting method according to the invention is characterized in that the melt during and after the filling in the cross-section first loses part of its kinetic energy resulting from the filling in cross-section and calms down before it flows into the mold cavity. This is achieved in particular by the fact that first about 1/5 of the melt required for a casting is introduced into the cross-flow, this quantum of melt calmed down, before under constant further filling of melt in the cross-flow of the actual casting, ie the influx of Melt in the mold cavity, takes place. It is thus for the filling of the melt in the cross-flow considerably more time available, as from a technological point of view and in view of a high casting quality for the inflow of the melt is optimal in the mold cavity.
- the filling of the melt in the cross-flow can thus be carried out particularly gently and with the minimization of turbulence, but in particular avoiding turbulence and foaming, without an increase in the time required for the melt to flow into the mold cavity.
- the impact of the melt jet and the melt flow in the cross-flow of particular importance. It is useful if the melt jet impinges on an inclined at an angle of 5 ° to 15 ° outwards, approximately perpendicular to the tilt axis of the casting mold and cross wall and flows directly or after one or more deflections in the longitudinal direction of the cross-flow, the contours
- the aforementioned conditions should be well rounded both at the beginning of the filling of the melt into the cross-section, ie at a cross-section of about 45 ° to 70 ° about its longitudinal axis, as well as during the tipping back of the casting mold and cross run and the continuous further filling of melt into the cross run are maintained.
- the tilting axis is tilted about the casting mold and cross-section through the wall, preferably the wall region on which the melt jet impinges. If this can not be realized, the melt jet must be adapted to the movement of the wall during the remindkippvorganges by means of a controllable in their movement Verg cordISS.
- a further improvement of the invention can be achieved in that the melt is not filled directly into the cross-flow, but in a pouring basin preferably arranged on an end face of the cross-flow.
- Figure 1 the schematic representation of a mold with laterally arranged cross run and a pouring basin on the front side of the cross run and a positioned ladle as Verg automatech, in
- FIG. 2 a shows the cross-section of the casting mold with laterally arranged cross-section
- FIG. 2 b shows the casting mold tilted by 50 ° with the cross-flow filled with melt
- FIG. 2 c the partially recessed casting mold with melt flowing into the mold cavity
- FIG. 2 d the completely back-tilted and with FIG Melt filled mold.
- FIG. 1 shows schmatisch a mold 1 for a cylinder head with laterally arrange ⁇ tem cross Run 2.
- a Eing electtümpel 3 is arranged at the rear end side of the cross barrel 2 .
- the rear end face 4 of the Eing electtümpels 3 is inclined at an angle of 10 ° relative to the vertical to the outside.
- the interior of the transverse run 2 is connected by four outlets 5 with the mold cavity of the mold 1.
- a spatially movable pouring spoon 6 which can be tilted about a transverse axis is positioned so that the melt flowing out of the pouring spoon 6 impinges on the rear end face 4 of the pouring basin 3, as indicated by the arrow 7, and in the longitudinal direction of pouring basin 3 and cross-section 2 flows into the cross-section 2.
- the casting mold 1 can be tilted about the axis 8
- FIGS. 2a to 2d illustrate the method according to the invention.
- FIG. 2a initially shows the cross section of the casting mold 1 with laterally arranged transverse run 2 and the mold cavity 9.
- the interior space of the transverse run 2 is connected to the mold cavity 9 through the outlets 5.
- Figure 2b shows the tilted by about 50 ° about the longitudinal axis 8 mold 1.
- the melt required for the casting is continuously filled by means of the controllable in its movement ladle 6 in the Eing automattümpel 3, in such a way that the melt jet 7 on the order 10 ° with respect to the vertical to outside, en inclined rear end wall 4 of the Eing devistümpels 3 and largely vortex-free in the longitudinal direction of the cross-flow 2 flows into this.
- FIG. 2b illustrates this method step. If the shrine level in the interior of the cross-section 2 reaches the outlets 5 (approx. 1/5 of the one for the Cast required melt then beflnden in the interior of the cross run 2), the melt begins to flow through the exhausts 5 along the mold side wall into the mold cavity.
- the mold 1 is now tilted back continuously, wherein continuously more melt from the ladle 6 in the Eing automattümpel 3 and thus the cross-2 is filled, calms down in Eing intelligenttümpel 3 and 2 and crosses along the side wall into the mold cavity 9 and fills it, as Figure 2c shows.
- the filling of the melt and the tilting back of the mold 1 are coordinated so that the mold 1 is completely tilted back when a filling of the mold cavity 9 has taken place to the feeder attachment. Finally, the feeders are filled up to the melt level shown in FIG. 2d.
