[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] Reference Figure 1 and Figure 2, the utility model provides an embodiment: a pouring riser for a long rail-shaped steel casting, comprising a pouring riser shell 1, the left and right sides of the pouring riser shell 1 are fixedly connected with L-shaped plates 3, the two L-shaped plates 3 are provided with a knob 4 on the side away from each other, the two knobs 4 are fixedly connected with a threaded column 5 on the adjacent side, the outer walls of the two threaded columns 5 are threadedly connected to the inner wall of the corresponding L-shaped plate 3, the adjacent sides of the two threaded columns 5 are rotatably connected with a mounting plate 6, the two mounting plates 6 are threadedly penetrated with two threaded knobs 7 on the side away from each other, the adjacent sides of the plurality of threaded knobs 7 are threadedly connected with a clamping plate 9, the front and rear sides of the top walls of the two clamping plates 9 are fixedly connected with sliders 11, the front and rear sides of the bottom wall of the pouring riser shell 1 are provided with two slide grooves 12, the tops of the two sliders 11 are respectively slidably connected with the corresponding slide grooves 12, the bottom wall of the pouring riser shell 1 is provided with a casting shell 15, and the front and rear sides of the pouring riser shell 1 are provided with a reinforcement mechanism 2;
[0030] Specifically, by turning the two knobs 4, the two threaded columns 5 begin to rotate on the inner wall of the corresponding L-shaped plate 3. This rotation not only achieves the displacement towards each other, but also provides the two mounting plates 6 with a tendency to rotate and displace. This design cleverly utilizes the mechanical principle, so that the device can be adaptively adjusted according to the casting shells of different lengths. In order to further ensure the stability of the mounting plate 6, we added a plurality of sliders 11 to the design to be slidably connected with the corresponding slide grooves 12. This connection method not only limits the rotation of the mounting plate 6, but also enhances the stability of the entire device. When the mounting plate 6 is restricted from rotating, they will drive the clamping plate 9 fixedly installed by the threaded knob 7 to move towards each other. In this way, the casting shell 15 can be firmly fixed, providing a solid foundation for the subsequent casting process. This fixed clamping device can not only adapt to casting shells of different lengths, but also has high flexibility. When the casting shell 15 needs to be installed or removed, the operator only needs to simply adjust the knob 4 to complete it easily. This convenient operation method not only improves work efficiency, but also reduces the difficulty of operation.
[0031] Reference Figure 1 and Figure 3 The reinforcement mechanism 2 includes two locking plates 201, the front and rear top ends of the two locking plates 201 are rotatably connected to the front and rear sides of the casting shell 1, the front and rear sides of the casting shell 1 are provided with rotation grooves 202, the front and rear sides of the casting shell 15 are fixedly connected with locking shells 203, the bottom of the adjacent side of the two locking plates 201 are respectively engaged with the side away from the corresponding locking shell 203, the left side of the two locking shells 203 is penetrated with a movable block 204, the right ends of the two movable blocks 204 are fixedly connected with a clamping plate 205, the left side of the bottom of the adjacent side of the two locking plates 201 is provided with a clamping groove 206, and the right sides of the two clamping plates 205 are respectively engaged with the corresponding clamping groove 206;
[0032] Specifically, the two locking plates 201 are rotated so that their bottoms are respectively engaged with the corresponding locking shells 203. In this step, the locking shell 203 plays a key role. It not only provides stable support for the locking plate 201, but also ensures the precise alignment of the locking plate 201 during the engagement process. When the locking plate 201 is fully engaged with the locking shell 203, the entire structure becomes more stable, laying a solid foundation for the subsequent casting process. Push the movable block 204 to the right. This action will drive the engaging plate 205 to move to the right until it is engaged with the engaging groove 206 provided on the left side of the bottom of the locking plate 201. This precise matching process ensures that the connection effect between the pouring shell 1 and the casting shell 15 reaches the best state.
[0033] This mechanical locking mechanism not only effectively improves the connection between the pouring shell and the casting shell, but also greatly reduces the instability during the casting process. This stability is crucial to ensure the quality and precision of the casting. In practical applications, this locking mechanism significantly improves the success rate of casting and reduces the scrap rate.
[0034] Reference Figure 2 and Figure 3 The outer walls of the two knobs 4 are fixedly connected with a plurality of anti-slip protrusions 13 at equal distances; the upper and lower sides of the two movable blocks 204 are fixedly connected with a plurality of anti-slip strips 207 at equal distances; the two knobs 4 are provided with a protective shell 14 on the far side thereof, and the adjacent sides of the two protective shells 14 are rotatably connected with the far side of the corresponding L-shaped plate 3 through a hinge;
[0035] Specifically, multiple anti-skid protrusions 13 can improve the static friction of the knob 4, and multiple anti-skid strips 207 can improve the anti-skid effect of the movable block 204, making it easier to pull the movable block 204. Two protective shells 14 can protect the knob 4 when it is fixed.
[0036] Reference Figure 1 and Figure 2 The left and right sides of the inner wall of the pouring shell 1 are both provided with inclined surfaces; the adjacent sides of the two clamping plates 9 are both fixedly connected with rubber pads 10; the middle parts of the multiple threaded knobs 7 are all fixedly connected with rubber rings 8;
[0037] Specifically, two inclined surfaces facilitate casting of casting liquid, two rubber pads 10 improve the fixing effect of the corresponding clamping plate 9, and multiple rubber rings 8 facilitate protection of the mounting plate 6, thereby reducing rotational damage to the mounting plate 6 caused by the threaded knob 7.
[0038] Working principle: When the casting shell 15 is fixed, the two knobs 4 are rotated according to the different lengths of the casting shell 15, so that the two threaded columns 5 are rotated on the inner wall of the corresponding L-shaped plate 3 to move toward each other, so that the two mounting plates 6 have a tendency to rotate and move. When the multiple sliders 11 are slidably connected with the corresponding slide grooves 12, the two mounting plates 6 are restricted from rotating, and then the two mounting plates 6 drive the clamping plates 9 fixedly installed by the threaded knobs 7 to move toward each other, thereby completing the fixing and clamping of the casting shell 15, making it easy to install or fix the casting shells 15 of different lengths. The casting shell 15 can be disassembled and then adapted to casting with different lengths, thereby improving the flexibility of the casting shell 1, and by rotating the two locking plates 201, under the action of the rotating groove 202, the bottoms of the two locking plates 201 are respectively engaged with the corresponding locking shells 203, and then by pushing the movable block 204 to the right, the engaging plate 205 is displaced to the right, and then engaged with the engaging groove 206 provided on the left side of the bottom of the locking plate 201, so as to facilitate improving the connection effect between the casting shell 1 and the casting shell 15, thereby reducing the instability during casting, thereby improving the success rate of casting.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
