Definitions

the present invention relates to a permanent mold with at least two mold cavities arranged side by side.
This permanent form is particularly suitable for use for direct falling pouring.
the falling pouring method enables a high liquid metal output to be achieved through controlled solidification.
the solidification can be further improved up to almost 100%.
the more favorable temperature gradient in the casting, i.e. the hottest metal in the upper part of the casting supports the desired solidification direction from bottom to top, where the feeder is placed.
the falling casting method is also used for smaller castings, but with a barrel system and with gates, which results in lower liquid metal output and higher stress on the permanent mold, which inevitably leads to a shorter service life.
the aim of the present invention is to propose a permanent mold with which, on the one hand, the advantages of the falling casting method can be used for lighter castings, and on the other hand, several castings can be cast at once.
the single figure shows a multiple permanent form 1, which is filled directly with a liquid metal 2 falling from above.
the liquid metal 2 flows from a container 3 via several pouring nozzles 5 simultaneously into the mold cavities 4 of the permanent mold 1.
the container 3 can be a holding furnace or a distributor with pouring nozzles. When using a distributor and a ladle, the amount of liquid metal should be adapted to the casting or castings so that the losses through Metal residues remain minimal.
the individual cavities are connected by means of compensation channels 6.
the pouring nozzle cross sections are also graduated. These measures guarantee that the same climbing speed and filling time are achieved in all cavities.
the connection is provided in the lower part of the mold cavities.
several compensating connections are necessary, which are preferably arranged one above the other in parallel. Since an irregular filling speed usually occurs at the beginning and at the end of the casting process, it is usually necessary to provide the compensating connections in the lower and in the upper part of the mold cavity.
the upper compensation connection can also be arranged between the feeders.
