- the invention relates to a device for producing workpieces, the device having at least one casting station for introducing a molten metal into molds, the device having a rotary table.
- a device of the type mentioned is for example from the DE 3422121 A1 known.
- shapes are arranged along the periphery of a rotary table.
- Each of the molds is part of a device for back pressure casting.
- a disadvantage of the known device is, inter alia, that the shapes can only be manipulated to a limited extent and the shapes cannot be easily introduced and removed from the rotary table. It is also disadvantageous that the number of pieces that can be produced with the device in a given time is very limited due to the design. From the FR 2394349 A1 It has become known to move molds radially directly on a rotary table without using mold carriers.
- the device has a plurality of mold carriers for the molds which are arranged on the rotary table, the mold carriers being displaceably mounted on the rotary table in a radial direction of the rotary table, the mold carriers in guides of the rotary table designed as guide rails can be displaced radially to the rotary table.
- molds which are held by the mold carriers can be manipulated on the rotary table in a simple manner.
- the invention enables the molds to be easily introduced and removed.
- the guides extend at least to an outer edge region of the rotary table and the Shapes can be ejected from the rotary table by radially moving the mold carriers in the guides.
- the productivity of the device can be increased by arranging processing stations around the rotary table, in particular for pouring a melt into the molds and / or cleaning the molds and / or for removing the workpieces and / or for removing the molds.
- the rotary table can be rotated about an axis by means of a drive, so that the mold carriers can be displaced between the processing stations by rotating the rotary table.
- the invention has a plurality of casting stations for introducing the molten metal into the molds, the number of casting stations being smaller than the number of mold carriers arranged on the rotary table .
- the casting stations can have casting spoons, the number of casting spoons being greater than the number of casting stations.
- This variant of the invention also enables the simultaneous introduction of melt at different points in the mold.
- a device 1 for producing workpieces by introducing a molten metal into molds 2 has a rotary table 3.
- a plurality of mold carriers 4 are arranged on the rotary table 3, in which the molds 2 are held on the rotary table 3.
- the mold carriers 4 are slidably mounted on the rotary table 3 in the radial direction of the rotary table 3.
- the mold carriers 4 are arranged in or on corresponding guides 5 of the rotary table 3.
- the guides 5 are designed as guide rails and can extend at least up to an outer edge region of the rotary table 2, so that the molds 2 can be discharged from the rotary table 3 by radial displacement of the mold carriers 4 in the guides 5.
- the guides 5 protrude slightly beyond the edge of the rotary table 3.
- the mold carrier 4 can have an upper part and a lower part.
- the mold 2 itself can be designed as a mold with an upper part and a lower part.
- the upper part of the mold 2 and a lower part of the mold 2 can be arranged on the lower part of the mold carrier.
- the upper part of the mold carrier 4 can be fork-shaped.
- the mold 2 or the mold can be opened by a vertical movement of the upper part of the mold carrier 4 and is accessible, for example, for cleaning.
- Processing stations can be arranged around the rotary table 3 and outside the rotary table 3.
- a casting station 6 for casting a melt into the molds 2 and a removal station 7 are provided.
- the corresponding mold 2 can be positioned in front of the casting station 6 by rotating the rotary table 3 and introduced into the casting station 6 by moving it in the radial direction of the rotary table 3.
- the rotary table 3 can be rotated about an axis by means of a drive, so that the mold carriers 4 can be displaced between the processing stations by rotating the rotary table 3. So after filling the mold 2 or the mold in the casting station 6 with the melt, the filled mold 2 is pushed back onto the rotary table 3 and by rotating the Turned round table 3 in the direction of a removal station 7. The rotation of the rotary table 3 is timed so that after the filled mold 2 has been transported on, a mold 2 that has not yet been filled comes to rest in front of the casting station 6. The filled mold 2 is preferably transported from the casting station 6 to the removal station 7 in two cycles.
- the metal melt in the mold 2 is cooled and solidified or solidified.
- the removal station 7 the mold 2 is opened and the workpiece is removed from the mold 2 onto one Transport means 12, for example a conveyor belt, placed and transported away.
- processing stations In addition to the processing stations shown, further processing stations not shown here can be provided, for example for cleaning the molds 2.
- Fig. 1 it can be seen that the molds 2 or molds can not only be discharged from the rotary table 3 but can also be introduced onto the latter. This enables an increase in productivity, since molds already prepared for filling with melt can be introduced and thus the cleaning of the molds and preparation of the molds for filling with melt are decoupled from the casting process.
- a plurality of casting stations 6 can also be arranged around the rotary table 3, the number of casting stations 6 being smaller than the number of mold carriers 4, however, in order for a mold 2 which has already been filled to be removed at the same time as a casting, in the removal station 7 or to discharge an already filled mold and thus to be able to operate the manufacturing process continuously.
- each pouring station can have 6 pouring spoons, the number of pouring spoons being greater than the number of pouring stations 6.
- each pouring station can have more than one pouring spoon with which the melt is poured into the molds 2. This makes it possible, for example, to pour molten metal into the mold 2 at different points. Metal melts of different compositions can also be poured into the mold 2 at different points.
