[0002] The carbon in cast iron exists in the form of flake graphite, and its fracture is gray, usually called gray iron. Because graphite is soft and has a lubricating effect, cast iron has good cutting, wear resistance and casting properties. However, its tensile strength is not enough, so it cannot be forged and rolled, and can only be used to make various castings, such as casting various machine tool beds, iron pipes, etc.

[0003] During the casting process, the pig iron raw materials usually need to be melted into liquid and then injected into the mold through a molten iron injection device to complete the casting.

DETAILED DESCRIPTION

[0021] 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.

[0022] Embodiment 1:

[0023] See also Figure 1-2 In this embodiment, a molten iron injection device for pig iron casting includes a mounting seat 1, a mounting frame 11 and a support frame 2 are arranged on the top of the mounting seat 1, and a molten iron ladle 13 is rotatably connected to the mounting frame 11. In order to facilitate the staff to move it during use, a universal wheel 14 is arranged at the bottom of the mounting seat 1 in this embodiment;

[0024] In order to facilitate the dumping of the molten iron ladle 13 during use, a transmission motor 21 is arranged on the top of the support frame 2 in this embodiment, and the output shaft of the transmission motor 21 is fixedly connected to the wire pile 22, and a traction rope 25 is arranged in the wire pile 22. This arrangement can effectively play a traction effect during use. The staff can drive the wire pile 22 to rotate by controlling the output shaft of the transmission motor 21, so that the traction rope 25 can drive the molten iron ladle 13 to change its angle, thereby achieving the dumping effect of the molten iron ladle 13. A support arm 23 is fixedly connected to one side of the support frame 2, and a pulley 24 is arranged at the other end of the support arm 23. The traction rope 25 is connected to the molten iron ladle 13 and maintains a sliding connection with the pulley 24; in the actual use process, it can effectively play a guiding effect. It is worth noting that the height of the support arm 23 is higher than the mouth height of the molten iron ladle 13, so as to ensure that it can dump cleanly, and when the molten iron ladle 13 rotates to a horizontal level, the connection between the traction rope 25 and the molten iron ladle 13 should be located in the same straight line with the pulley 24 in the vertical direction.

[0025] In order to achieve the effect of height adjustment of the limit assembly 3, a slide groove 15 is provided on the mounting seat 1 in this embodiment, and a limit groove 16 is provided on the slide groove 15. A support plate 17 is provided in the slide groove 15, and an electric push rod 18 is provided on the support plate 17. The push rod end of the electric push rod 18 is fixedly connected to the limit assembly 3, and four limit units 4 are slidably connected to the limit assembly 3. In the actual use process, the staff can control the electric push rod 18 to enable the limit assembly 3 to produce an effect of up and down displacement, so as to control the limit effect of the limit assembly 3 and the limit unit 4 on the molten iron ladle 13. In the process of moving the molten iron ladle 13, the staff can control the electric push rod 18 to enable the push rod to drive the limit assembly 3 to produce an effect of upward displacement, so that the limit unit 4 on the limit assembly 3 can achieve the limit of the molten iron ladle 13, avoiding the occurrence of swaying in the process of moving the molten iron ladle 13, thereby ensuring that the molten iron inside it will not splash out, causing the waste of raw materials and the injury of the staff.

[0026] Embodiment 2:

[0027] See also Figure 3-4 In order to limit the position of the limit assembly 3 during use, the limit assembly 3 in this embodiment is provided with a mounting platform 31, and a limit block 33 is provided on the mounting platform 31, and the limit block 33 is slidably connected with the limit groove 16. Four mounting grooves 32 are provided on the mounting platform 31. This connection method effectively ensures that the mounting platform 31 can be more stable during the sliding process in the slide groove 15, thereby ensuring that it can play a good fixing effect on the molten iron ladle 13, and avoids the situation where the limit unit 4 cannot play a fixing effect on the molten iron ladle 13 due to the deviation of the mounting platform 31.

[0028] In order to achieve the effect of limiting the ladle 13, a limiting platform 41 is provided on the limiting unit 4 in this embodiment, a slider 43 is fixedly connected to the bottom of the limiting platform 41, the slider 43 is slidably connected to the mounting groove 32, a support spring 44 is provided on the slider 43, and the other end of the support spring 44 is fixedly connected to the inner wall of the mounting groove 32. The limiting platform 41 is provided with a fixing groove 42. This connection method enables it to adapt to ladles 13 of different sizes, and effectively ensures that it can avoid the occurrence of swaying during use.

[0029] As a preferred technical solution in the present embodiment, when the staff needs to limit the molten iron ladle 13 during use, they can first control the electric push rod 18 so that the push rod can drive the mounting platform 31 to produce an upward displacement effect, and in the process of the mounting platform 31 moving upward, the four limit platforms 41 can be driven to move upward. In the process of the limit platform 41 moving upward, the fixed groove 42 can contact the bottom of the molten iron ladle 13. At this time, in the process of the limit platform 41 continuously moving upward, the fixed groove 42 is completely fitted with the bottom of the molten iron ladle 13. At this time, the four limit platforms 41 all produce an outward sliding effect along the center of the mounting platform 31. In the process of the limit platform 41 sliding outward, the slider 43 can be driven to slide, so that the slider 43 is compressed by force, and a thrust in one direction is generated so that the limit platform 41 and the fixed groove 42 can always keep in contact with the molten iron ladle 13, so that it can have a good limiting effect on the molten iron ladle 13, and avoid the shaking of the molten iron ladle 13 during the movement of the molten iron ladle 13.

[0030] The working principle of the above embodiment is:

[0031] 1. When it is necessary to limit the iron ladle 13 during use, the staff can first control the electric push rod 18 so that the push rod can drive the mounting table 31 to produce an upward displacement effect, and in the process of the mounting table 31 moving upward, the four limit tables 41 can be driven to produce an upward displacement effect. In the process of the limit table 41 moving upward, the fixed groove 42 can contact the bottom of the iron ladle 13. At this time, in the process of the limit table 41 continuously moving upward, the fixed groove 42 is completely fitted with the bottom of the iron ladle 13. At this time, the four limit tables 41 all produce an outward sliding effect along the center of the mounting table 31. In the process of the limit table 41 sliding outward, the slider 43 can be driven to slide, so that the slider 43 is compressed by force, and a thrust in one direction is generated so that the limit table 41 and the fixed groove 42 can always keep in contact with the iron ladle 13, so that it can have a good limiting effect on the iron ladle 13, avoiding the shaking of the iron ladle 13 during the movement of the iron ladle 13.

[0032] 2. When the ladle 13 needs to be dumped, the staff can control the electric push rod 18 to drive the mounting table 31 to move downward, so that the limiting unit 4 cancels the limiting effect on the ladle 13, and then control the output shaft of the transmission motor 21 to drive the wire pile 22 to rotate, so that the traction rope 25 can drive the ladle 13 to change its angle, thereby achieving the dumping effect of the ladle 13.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
