Method for processing, in particular casting, a material, casting mold for carrying out the method and articles produced by the method or in the casting mold

Abstract

A method for producing articles in a mold includes bringing a material into a free-flowing state, introducing the material into the mold via a bottom-casting principle, and solidifying being carried out according to a top-casting principle. The material, viewed in a flow direction of the material, is first introduced into a pouring basin of a runner, then flows through the runner, thereafter through a storage space that is located upstream from a cavity and that is arranged underneath the cavity, and from there into the cavity. Thereafter the mold including the sub-parts of the mold is pivoted so that the storage space takes over the function of a feeder or riser.

What is claimed is: 
     
         1 . A casting mold or ingot mold for carrying out a method for casting a material by bringing the material into a free-flowing state by heating and introducing the material into the casting mold or ingot mold according to a principle of gravity casting, said casting mold or ingot mold comprising a runner with a pouring basin, a storage space attached to the runner as well as a cavity attached thereto with a downsprue, wherein the storage space is arranged underneath the downsprue of the cavity and wherein the casting mold can be pivoted together with pouring basin, runner, storage space and cavity. 
     
     
         2 . The casting mold according to  claim 1 , wherein the runner leading into the storage container comprises a portion which lies lower than the storage container. 
     
     
         3 . The casting mold according to  claim 1 , wherein the cavity and the runner are provided at an angle relative to each other. 
     
     
         4 . The casting mold according to  claim 1 , wherein both the cavity and the runner are arranged at an angle in relation to a plane extending between them, which plane extends, at least approximately, perpendicularly to the horizontal. 
     
     
         5 . The casting mold according to  claim 3 , wherein cavity and runner are provided at a blunt angle relative to each other. 
     
     
         6 . The casting mold according to  claim 1 , wherein cavity and runner are provided at such an angle relative to each other that, when the mold is pivoted into a position in which the storage space comes to lie above the cavity—i.e. the solidifying position—and the storage space can act as feeder or riser, the runner finds itself in a position in which spilling out of the liquid casting substance from the storage space is avoided. 
     
     
         7 . The casting mold according to  claim 6 , wherein the runner, in the solidifying position, points obliquely upwards relative to the horizontal. 
     
     
         8 . The casting mold according to  claim 1 , wherein cavity and runner are arranged relative to each other in such a way that the mold can be pivoted such that the runner is leading. 
     
     
         9 . The casting mold according to  claim 1 , wherein two mold halves surrounding both the runner and the storage space as well as the cavity are separated from each other by separating grooves and the casting mold is pivotable about an axis which, at least approximately, extends in parallel to its separating-groove plane. 
     
     
         10 . The casting mold according to  claim 1 , wherein the mold—with the storage container at the top—can be filled with melt according to the bottom-casting principle and wherein the mold is pivotable and solidification of the melt is effected with the storage space acting as feeder or riser at the top. 
     
     
         11 . The casting mold according to  claim 1 , wherein a closure is provided on top of the pouring basin. 
     
     
         12 . The casting mold according to  claim 1 , wherein a slide is provided in the area of the runner. 
     
     
         13 . A casting product, wherein it consists of a light-metal alloy, such as in particular an aluminum alloy manufactured according to  claim 1  by the gravity method. 
     
     
         14 . A method for casting a cast part from a metal melt comprising the following steps:
 a) providing a rotatably-mounted casting mould comprising a mould cavity shaping the cast part, a feed system for feeding the mould cavity with metal melt and a pour channel, via which the feed system can be filled with metal melt, wherein the feed system is arranged in relation to the mould cavity of the casting mould so that when the casting mould is rotated into a fill position the filling of the mould cavity with the metal melt takes place via the feed system against the acting direction of gravity, and wherein a filling opening, provided for filling the metal melt, of the pour channel is arranged on a lateral side of the casting mould remotely from a mouth of the pour channel into the feed system so that the filling opening of the pour channel is arranged in the respective fill position of the casting mould above the mouth of the pour channel into the feed system;   b) aligning the casting mould in a fill position in which metal melt filled in the pour channel as a consequence of the effect of gravity flows through the pour channel, wherein the main flow direction of the metal melt makes an angle relative to the acting direction of gravity;   c) filling the casting mould aligned in the fill position with the metal melt, until the casting mould, including the pour channel, is completely filled with metal melt;   d) rotating the casting mould into a solidification position, in which as a result of the effect of gravity the melt present in the feed system is pushed against the melt present in the mould cavity;   e) holding of the casting mould in the solidification position until the metal melt present in the casting mould has reached a certain solidification state;   f) de-moulding of the cast part.   
     
     
         15 . The method according to  claim 14 , wherein in connection to step c), the casting mould is sealed with a stopper placed in the filling opening of the pour channel, whereby rotating in step d) then takes place with a sealed casting mould. 
     
     
         16 . The method according to  claim 14 , wherein an axis of rotation of the casting mould is aligned horizontally. 
     
     
         17 . The method according to  claim 14 , wherein the pour channel of the casting mould runs linearly. 
     
     
         18 . The method according to  claim 14 , wherein the filling opening of the pour channel is allocated to an underside of the casting mould. 
     
     
         19 . The device according to  claim 1 , wherein the axis of rotation of the casting mould is aligned horizontally.
