Technical Field

[0001] The utility model relates to the technical field of casting equipment, in particular to a fixing device for the interface of a pouring channel ceramic pipe for casting. Background Technique

[0002] As is well known, the pouring system we usually refer to is essentially composed of sections of ceramic pipes spliced together. According to its nature, it can be divided into sprue, runner and ingate. The molten iron in the ladle flows through the sprue, runner and ingate in sequence, and finally enters the casting cavity. The ceramic pipe is an impervious ceramic pipe made of clay with glazed inner and outer surfaces, and can be divided into straight pipes, special-shaped pipes, floor drain pipes and other varieties.

[0003] However, during the process of arranging sections of pouring channel ceramic pipes, due to the impact of pouring liquid and the deviation of the installation position being uneven, the ceramic pipe may tilt or the interface of the ceramic pipe may be misaligned. When pouring is carried out with the ceramic pipe interface in a misaligned state, the molten iron cannot enter the pouring channel correctly according to the process flow rate and process path. This will directly scour the side wall of the ceramic pipe and the sand mold, and will also entrain gas and sand grains into the cavity, seriously affecting the quality of the casting. For this reason, we have proposed a fixing device for the interface of a pouring channel ceramic pipe for casting. Content of the Utility Model

An auxiliary steel bar is movably sleeved inside the side of the clamp, and a pressing plate is installed inside the auxiliary steel bar through a spring steel.

[0006] Preferably, the first threaded rod base and the second threaded rod sequentially pass through the inside of the disc base and the long strip steel plate, and at the same time, the long strip steel plate is kept parallel to the upper end of the disc base.

[0007] Preferably, there are two groups of ceramic pipe bodies, and the connection of the two groups of ceramic pipe bodies is arranged directly above the second threaded rod.

[0008] Preferably, a buffer pad is installed inside the clamp, and the clamp drives the buffer pad to contact the ceramic pipe body.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 A fixing device for the interface of a pouring channel ceramic pipe for casting, comprising a disc base 1. The inside of the disc base 1 is threadedly connected with a first threaded rod seat 2. By rotating the first threaded rod seat 2, a threaded movement is carried out between the first threaded rod seat 2 and the disc base 1, that is, the height of the long strip steel plate 4 is adjusted. The upper part of the first threaded rod seat 2 is movably sleeved with a second threaded rod 3. By rotating the second threaded rod 3, the top end of the second threaded rod 3 extends upward, that is, the second threaded rod 3 can assist in supporting the position of the ceramic pipe body 7. The outside of the upper end of the second threaded rod 3 is threadedly sleeved with a long strip steel plate 4. Two groups of semi-circular clamps 5 are respectively installed on the upper parts of both ends of the long strip steel plate 4. A set of fastening bolts 6 are installed between the joints of the two groups of clamps 5. By rotating the fastening bolts 6, the fastening bolts 6 drive the clamps 5 to be sleeved outside the ceramic pipe body 7, that is, the position of the ceramic pipe body 7 is assisted in being clamped and limited. At the same time, the ceramic pipe body 7 is clamped inside the clamp 5. An auxiliary steel bar 8 is movably sleeved inside the side of the clamp 5. A pressing plate 10 is installed on the inner side of the auxiliary steel bar 8 through a spring steel 9. By adjusting the position of the auxiliary steel bar 8, the pressing plate 10 is controlled to move inward, and the pressing plate 10 limits the position of the ceramic pipe body 7 from different directions, avoiding the position of the ceramic pipe body 7 from shifting during the pouring of molten steel inside the ceramic pipe body 7.

[0022] Please refer to Figure 2 The first threaded rod seat 2 and the second threaded rod 3 sequentially pass through the inside of the disc base 1 and the long strip steel plate 4. At the same time, the long strip steel plate 4 remains parallel to the upper end of the disc base 1. By rotating the first threaded rod seat 2, a threaded movement is carried out between the first threaded rod seat 2 and the disc base 1, that is, the height of the long strip steel plate 4 at the upper end of the disc base 1 can be adjusted, and at the same time, the position of the long strip steel plate 4 is not affected. At the same time, by rotating the second threaded rod 3, a threaded movement is carried out between the second threaded rod 3 and the long strip steel plate 4, that is, the whole of the second threaded rod 3 can move upward. The second threaded rod 3 supports the middle part of the ceramic pipe body 7, avoiding the position of the ceramic pipe body 7 from shifting, and ensuring the stability during the calibration of the position of the ceramic pipe body 7.

[0023] Please refer to Figure 1, the earthenware pipe body 7 includes two groups, and the connection part of the two groups of earthenware pipe bodies 7 is arranged directly above the second threaded rod 3. There are two groups arranged through the earthenware pipe body 7, and the connection part of the earthenware pipe body 7 is arranged above the second threaded rod 3. When the second threaded rod 3 moves upward, the second threaded rod 3 supports the connection part of the earthenware pipe body 7, avoiding the settlement downward of the connection part of the earthenware pipe body 7 under pressure when the liquid poured inside the earthenware pipe body 7 flows, resulting in the influence on the pouring efficiency.

[0024] Please refer to Figure 3 , a buffer pad 11 is installed inside the clamp 5. The clamp 5 drives the buffer pad 11 to contact the earthenware pipe body 7. By tightening the fastening bolt 6, the fastening bolt 6 controls the clamp 5 to move inward. At the same time, the clamp 5 drives the buffer pad 11 to clamp the earthenware pipe body 7, improving the stability when clamping and limiting the positions of earthenware pipe bodies 7 with different diameters.

[0025] Please refer to Figure 3 , an arc-shaped groove is formed inside the clamp 5. At the same time, both ends of the auxiliary steel bar 8 are arranged inside the arc-shaped groove. By forming the arc-shaped groove inside the clamp 5 and arranging the auxiliary steel bar 8 inside the arc-shaped groove, after adjusting the position of the auxiliary steel bar 8 inside the arc-shaped groove, according to the different installation positions of the earthenware pipe body 7, the auxiliary steel bar 8 is controlled to move to different positions outside the earthenware pipe body 7.

[0026] Please refer to Figure 4 , the inner side of the pressing plate 10 is arc-shaped. At the same time, the inner side of the pressing plate 10 contacts the outside of the earthenware pipe body 7. By the inner side of the pressing plate 10 being arc-shaped and the spring steel 9 being arranged between the auxiliary steel bar 8 and the pressing plate 10, the spring steel 9 pushes the pressing plate 10 to move inward, that is, the pressing plate 10 contacts the outside of the earthenware pipe body 7. At the same time, the pressing plate 10 performs extrusion and limiting processing on the position of the earthenware pipe body 7. During the process of limiting the position of the earthenware pipe body 7, it is avoided that the whole earthenware pipe body 7 moves to the side, resulting in the problem of the deviation of the position of the earthenware pipe body 7 being affected.

[0027] Working principle: During use, two groups of ceramic pipe bodies 7 are spliced together. At the same time, the clamp 5 is controlled to be sleeved outside the two groups of ceramic pipe bodies 7, and the fastening bolt 6 is tightened. The fastening bolt 6 controls the clamp 5 to be sleeved outside the ceramic pipe body 7. According to the different positions of the ceramic pipe body 7, the second threaded rod 3 is rotated. The second threaded rod 3 can provide auxiliary support according to the different heights of the ceramic pipe body 7. At the same time, the first threaded rod base 2 is rotated. The first threaded rod base 2 can adjust the overall height of the long strip steel plate 4 without affecting the position of the long strip steel plate 4, improving the stability when the position of the ceramic pipe body 7 is limited. At the same time, the position of the auxiliary steel bar 8 is adjusted. The auxiliary steel bar 8 moves to different positions outside the ceramic pipe body 7. At the same time, the pressing plate 10 is controlled to assist in supporting the position of the ceramic pipe body 7, effectively avoiding the inclination of the sprue ceramic pipe and the misalignment of the ceramic pipe joints; during pouring, the molten iron can smoothly enter the runner, avoiding the erosion of the ceramic pipe joints and the side walls of the ceramic pipe by the molten metal, and ensuring operation safety, reducing the risks of pouring leakage and quality. In addition, this fixing device is designed to be detachable, which is convenient for disassembly and cleaning after casting is completed, improving work efficiency.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
