Problems solved by technology

However, before turning brings casting defects usually caused by air bubbles or cooling tracks in the casting
Such casting defects are due to the fact that the melt has cooled so sharply in the mold before the mold is rotated that an uncontrolled solidification front (or cooling track) itself forms or that the melt returns in the mold under the influence of contained air. shrink

Embodiment Construction

[0059] Casting G is here the engine module of the four-cylinder internal combustion engine. In this example, an aluminum casting melt was used as the casting metal.

[0060] The device 1 comprises a cylindrical casting chamber Z, which is shown in the figures with a circular cross-section, and is arranged on two pulleys 2, 3 and is driven in rotation by a driving device (not shown), in which casting chamber A flat assembly base plate 4 is fixed in it, and guide plates 5 are arranged parallel to the assembly base plate 4 and kept at a distance.

[0061] A base plate 6 is placed on the upper side of the mounting base 4 corresponding to the guide plate 5 . The base plate is a part of the mold F composed of a plurality of molded parts and cores. The base plate 6 has a plurality of lateral receptacles, in which each a front slide 7 , 8 with a correspondingly shaped attachment is accommodated, so that the front slide 7 , 8 is positively seated on the base plate 6 . With respect t...

Abstract

The invention relates to a method and a device for casting a cast part G from a metal melt M. During the method according to the invention, a casting mold F comprising a mold cavity H that shapes the cast part G, a feed system 10 and a pouring channel 13, said casting mold being mounted in a bogie, is rotated to a fill position and filled with a metal melt. As a consequence of the effect of gravity, the melt flows through the pouring channel, wherein the main flow direction of the melt makes an angle relative to the acting direction of the force of gravity. The filling is continued until the casting mold F and the pouring channel 13 are completely filled with metal melt M. Then, the casting mold F is sealed by a stopper 18 placed in the fill opening 14 of the pour channel 13, and is rotated to a solidification position in which the melt M present in the feed system 10 is pushed against the melt M present in the mold cavity H. The casting mold G is held in the solidification position until the metal melt M present in the casting mold F has reached a state of solidification in which the cast part G can be de-molded.

Description

technical field [0001] The invention relates to a method for casting a casting from a metal melt, and to a device suitable for carrying out the method. The metal melt processed according to the invention is a light metal melt, preferably a melt based on aluminum or an aluminum alloy. Background technique [0002] The solidification process of the melt in the mold and the feed required to balance the shrinkage can seriously affect the properties of the casting. Thus, the filling of the molten mold in a continuous process in order to avoid a large melt flow in the mold, with subsequent uniformly distributed solidification on the side of the mold opposite the feeder, enables an even distribution of its properties. [0003] The quality of high-quality casting products can be produced by so-called "rotary casting". In the prior art, DE 100 19 309 A1 discloses a casting method which can be used to produce high-quality castings. Wherein, the melt container containing the metal m...
