Description

Technical Field

[0001] The utility model relates to the technical field of ductile iron production, in particular to a casting device for ductile iron production. Background Technique

[0002] Ductile iron is a high-strength cast iron material developed in the 1950s of the 20th century. Its comprehensive performance is close to that of steel. Based on its excellent performance, it has been successfully used in casting some parts with complex stress, high requirements for strength, toughness, and wear resistance. When producing ductile iron, a mold is needed, and the molten iron is cast into the mold through a casting device to realize the casting and forming of ductile iron. When the existing casting device works, it needs to rely on a driving mechanism such as a hydraulic rod to push the ladle to rotate and tilt, so as to pour the molten iron in the ladle from the pouring gate into the mold.

[0003] However, the existing casting ladle has certain defects in actual use. Most of them are integrally arranged. After casting, there will be a certain amount of molten iron and the like remaining inside the casting ladle. Due to its relatively large size, it is not convenient to clean it after use, which affects the next casting operation. Content of the Utility Model

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model: A pouring device for ductile iron production includes a pouring ladle 1 (i.e., a molten iron ladle) for containing molten iron. Among them, there are also pouring molds and other relatively mature technologies, which will not be elaborated here. It can facilitate the casting and molding of ductile iron materials. The two pouring ladles 1 are spliced into a whole, which can be easily disassembled and facilitate subsequent cleaning and other operations. The guide rail sliders 8 of two groups of moving components are installed under the moving plate 2, and they are adapted to be equipped with a linear guide device 4 (partial view, which can drive the guide rail slider 8 to reciprocate through a linear motor or other moving devices, which are relatively mature technologies and will not be elaborated here). It can facilitate the overall movement of the moving plate 2 and the pouring ladle 1, facilitate its movement, and facilitate the completion of the pouring operation.

[0023] Please refer to Figures 1-5, in order to facilitate the rotation and flipping of the casting ladle 1, facilitate the casting operation, and also facilitate automatic resetting, two groups of vertical plates 3 are symmetrically welded on the moving plate 2. A cavity 20 of the rotating assembly is provided inside the vertical plate 3, and a rotating rod 19 is connected inside through a scroll spring 21. The rotating rod 19 passes through the cavity 20 and extends to the outside to be provided with a rotating plate 7, and the rotating plate 7 is connected with the clamping assembly, which can facilitate the clamping of the casting ladle 1 and facilitate subsequent rotation operations. A cross plate 5 is welded between the two vertical plates 3. A motor 6 can be fixedly installed on the cross plate 5 through a mounting seat. The output end of the motor 6 is fixedly installed with a rotating shaft 10 through a coupling. Two sets of rope winders 11 are installed on the rotating shaft 10, and a connecting rope 9 (the material can be steel wire rope or other materials to ensure its strength) is wound and retracted on them, which can facilitate operations such as winding. A through hole for the connecting rope 9 to pass through is provided on the cross plate 5. A connecting ring 16 is welded at the rear end of the casting ladle 1, and the end of the connecting rope 9 is connected to the connecting ring 16 (it can be fixedly connected by means of a connecting buckle or the like, which can facilitate disassembly and removal operations).

[0024] Please refer to Figures 1-5 , in order to facilitate the clamping of the casting ladle 1, facilitate splicing, and thus facilitate the holding of molten iron, facilitate the casting operation, and also facilitate subsequent separation operations, electric push rods 12 of the clamping assembly are equidistantly installed on the side wall of the rotating plate 7. The output end of the electric push rod 12 is installed with a clamping seat 13 (the structure is as Figure 3 shown), which can facilitate the clamping and lifting operations on the side and bottom of the casting ladle 1 to ensure firmness. A clamping groove 15 is provided on the side wall of the casting ladle 1, and a cushion pad 14 adapted to the clamping groove 15 is bonded on the clamping seat 13 to ensure the clamping effect. A plugging strip 17 of the plugging assembly is bonded at the opening end of one of the casting ladles 1, and a plugging groove 18 is provided at the corresponding position of the other one, which is convenient for splicing operations, and also convenient for subsequent separation and cleaning of the inside.

[0025] Working principle: When the present utility model is in use, the electric push rod 12 extends, driving the two clamping seats 13 to approach each other. The cushion pads 14 thereof enter into the clamping grooves 15, and in cooperation with the clamping seats 13, the casting ladle 1 can be clamped and lifted. Continuing to extend, the two casting ladles 1 can be driven to approach each other. The splicing operation is completed by inserting the inserting strip 17 into the inserting groove 18. By the operation of the linear guide device 4, the moving plate 2 on the guide rail slider 8 is driven to move, and it can be conveniently moved to the place for taking molten iron (it can be a melting furnace or the like, which is a relatively mature technology and will not be elaborated here). At this time, by the operation of the linear guide device 4 again, the casting ladle 1 filled with molten iron can be moved to the side of the casting mold. At this time, the motor 6 rotates forward, driving the rotating shaft 10 and the rope winder 11 to rotate, and the connecting rope 9 is wound up, driving the casting ladle 1 to rotate and tilt. At the same time, the rotating rod 19 rotates accordingly, and the scroll spring 21 stores potential energy, and the casting operation can be carried out. After the casting is completed, the motor 6 rotates reversely, and the connecting rope 9 can be payed out. Under the action of the self-weight of the casting ladle 1 and the like and the potential energy of the scroll spring 21, it returns to its original position, and then rotates back to its original position to complete the casting process. When it is necessary to clean the interior, the electric push rod 12 can be contracted, driving the two casting ladles 1 to move away from each other, and the inserting strip 17 moves away from the inserting groove 18, and the splitting operation can be completed, and then it is convenient to clean the interior. When auxiliary tilting is required during cleaning, the motor 6 can be rotated forward to drive it to rotate and tilt.

[0026] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
