Description

Technical Field

[0001] The utility model relates to the technical field of cast iron processing equipment, in particular to a fixed-point casting device for a cast iron casting process. Background Art

[0002] In the process of cast iron, casting is one of the essential processes. Usually, the method used for casting directly affects the quality of the finished product. When casting, the molten iron is first slowly poured from the medium frequency furnace into the preheated casting device, and then the workers or mobile devices lift and move the casting device containing the molten iron, and use the pouring of the casting device to pour the molten iron into the mold to complete the casting;

[0003] Generally, the casting device adopts a gantry structure. When the casting device moves to the casting point, the casting bucket is tipped over by manpower or by a hydraulic cylinder for casting. The manpower method is very dangerous, and the hydraulic cylinder method can generally only push the casting bucket to tip in a preset direction, that is, to cast at a specific point. If operations need to be performed at multiple different positions, manual adjustment is required, which is not flexible enough. Utility Model Content
