Cooling plate

摘要

The present invention refers to a cooling plate for the material casted in casting moulds. The cooling plate (7) has the base of any shape. Inside the body of the plate (7) there is a hollow channel (12) in the shape of a double coil through which a cooling agent flows. Between the channel (12) there is a channel (13) through which a cooling agent with a lower temperature flows. Along the path of the channel (12) there are ports in which slot nozzles (11) and/or straight nozzles (8) and/or nozzles with an adjusted flow direction (9) and/or multipoint nozzles (10) are installed. Under the bottom of the sand mould (1) mounted on the cooling plate (7) between the bottom of the mould (1) and the upper surface of the cooling plate (7), there is a cooling agent flow chamber (5). The cooling plate (7) is mounted at the casting station, where under the bottom of the cooling plate (7) there is a chamber through which the agent cooling the bottom surface of the cooling plate (7) flows. Between the cooling plate (7) and the bottom of the casting (2) there is a separating layer (3) of the sand mould (1) inside which/ in the sand channels (4), there are straight nozzles (8), slot nozzles (11), and nozzles with an adjusted flow direction (9). For castings that are oval in shape, the cooling element is equipped with additional multipoint nozzles (10).
