Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of ductile iron, and specifically relates to a high-silicon solution-strengthened ductile iron casting device. Background Art
[0002] Ductile iron is a high-strength cast iron material, and 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 forces and high requirements for strength, toughness, and wear resistance. Among them, casting is carried out through pouring. During the pouring process, rare earth magnesium alloy is used as a spheroidizing agent, and through chemical reactions, graphite is formed into a spherical shape, thereby improving the toughness and strength of the cast iron.
[0003] A patent application with the publication number CN216327560U discloses a casting device for preparing high-silicon solution-strengthened ductile iron, including a fixing frame. There is ductile iron on the fixing frame. An inner clamping mechanism is arranged on the fixing frame, and the inner clamping mechanism can clamp the ductile iron. There is an upper sleeve mechanism on the fixing frame that can adjust the clamping state of the inner clamping mechanism. When the inner baffle moves upward, spring one will gradually recover its deformation. When spring one recovers its deformation, the fixed rod remains stationary. At the same time, the upper locking sleeve will leave the four clamping plates, and at the same time, spring two will expand the clamping plates through its own elastic force, and the clamping plates will rotate and open away from the ductile iron. By using the upward movement of the fixed rod, the four clamping plates will automatically reset without manual operation, further improving the operation convenience.
[0004] The above-mentioned solution still has some problems in actual use. During the melting process, if the pouring speed is too fast, a large amount of gases such as hydrogen, oxygen, and nitrogen may be generated, and the molten metal may absorb a large amount of gases. If these gases are not fully discharged during the pouring process, bubbles will be formed, and these bubbles will affect the appearance of the casting. To solve this problem, the prior art will apply an anti-foaming agent to the mold before pouring to prevent the generation of bubbles. However, when the anti-foaming agent is applied to the mold, since the casting equipment and the mold are integrated and the mold cannot be taken separately, when applying the anti-foaming agent to the mold, the high-temperature injection liquid in the casting equipment will transmit high temperature to the mold. At this time, the excessively high temperature around the mold may cause discomfort to the operator and affect the application of the anti-foaming agent. Therefore, the operator can only apply the anti-foaming agent to the mold before the injection liquid is made. However, after the casting is demolded, the production of the next casting needs to be carried out in a timely manner, and the above-mentioned application method cannot be carried out during cyclic pouring.
[0005] Therefore, the present invention provides a high-silicon solution-strengthened ductile iron casting device. Summary of the Invention

[0031] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners. Embodiment 1
[0032] As Figures 1 to 9As shown in the figure, a high-silicon solution-strengthened ductile casting device according to an embodiment of the present invention includes a base frame 1. A placement platform 2 is provided at the upper end of the base frame 1. A movable platform 4 is rotatably connected to the surface of the placement platform 2. A storage structure 5 is provided on the surface of the movable platform 4. A casting structure 3 is provided at one end of the upper end of the base frame 1 near the placement platform 2. An adjustment structure 6 is provided on the surface of the casting structure 3. The storage structure 5 includes: a storage frame 51, the storage frame 51 is slidably connected to the surface of the movable platform 4; a discharge port 52, the discharge port 52 is provided at one end of the storage frame 51; the casting structure 3 includes: a lower mold 31, the lower mold 31 is provided at the upper end of the base frame 1; a casting groove 35, the casting groove 35 is opened on the surface of the lower mold 31; an upper mold 32, the upper mold 32 is slidably connected to the upper end of the lower mold 31; a casting port 34, the casting port 34 is opened on the surface of the upper mold 32; the adjustment structure 6 includes: a rotating plate 604, the rotating plate 604 is rotatably connected to the surface of the base frame 1; a pressing strip 611, the pressing strip 611 is provided at one end of the rotating plate 604, and the pressing strip 611 is in contact with the casting groove 35.
[0033] Specifically, for a high-silicon solution-strengthened ductile iron casting device of this solution, before casting, high-quality pig iron, scrap steel, alloy additives, and silicon elements are first selected as raw materials. Subsequently, the raw materials are put into the storage frame 51 in a certain proportion for melting. By adjusting the internal temperature of the storage frame 51, it is ensured that the materials are melted into molten iron and impurities are effectively removed, and this molten iron is the injection liquid. A spheroidizing agent, such as heavy magnesium and light ferroalloy, is added to the molten iron to form spherical graphite, so as to improve the fracture performance and plasticity. Subsequently, the storage frame 51 and the molten iron inside it are kept warm for a period of time to uniformly dissolve elements such as silicon in the iron matrix, completing the solution treatment. At this time, the supersaturated precipitates are eliminated, the hardness and strength are increased, and the wear resistance of the subsequent cast iron can be improved, making it perform better in aspects such as friction wear and impact wear. After the solution treatment is completed, the storage frame 51 is started, and the storage frame 51 will slide along the surface of the moving platform 4. Subsequently, when the storage frame 51 moves to one end close to the upper mold 32, the upper mold 32 is started, and the upper mold 32 will move downward and finally contact the lower mold 31. At this time, the moving platform 4 is started, and the moving platform 4 will rotate along the surface of the placement platform 2. Finally, the injection liquid inside the storage frame 51 can flow into the inside of the casting port 34 through the discharge port 52 and finally flow into the inside of the casting groove 35 to complete the casting. However, if the casting speed is too fast, a large amount of gases, such as hydrogen, oxygen, and nitrogen, may be generated. The molten metal may absorb a large amount of gases. If these gases are not fully discharged during the casting process, bubbles will be formed. These bubbles, as air pockets, will cause pores to adhere to the surface of the casting, and its strength is much lower than that of the iron material of the same volume. Therefore, the bubbles in the casting will significantly reduce the strength and toughness of the casting, thereby affecting its overall mechanical properties. For this reason, an adjustment structure 6 is designed. When the storage frame 51 moves towards the upper mold 32, the rotating plate 604 is started, and the rotating plate 604 will drive the pressing strip 611 to rotate. The surface of the pressing strip 611 is coated with an antifoaming agent. The pressing strip 611 will finally contact the inner wall of the casting groove 35 and evenly apply the antifoaming agent to the inner wall of the casting groove 35. These antifoaming agents can improve the distribution of the injection liquid on the mold surface and increase its fluidity. This improvement helps the injection liquid to fill the mold more evenly and reduces the generation of bubbles. Subsequently, when the upper mold 32 moves downward, the rotating plate 604 is started again, and the rotating plate 604 will drive the pressing strip 611 to reset. After the rotating plate 604 is reset, the upper mold 32 and the lower mold 31 are also in contact. At this time, when the injection liquid enters the inside of the casting groove 35, due to the antifoaming agent on the inner wall of the casting groove 35, pores will not be formed on the surface of the casting, and the antifoaming agent also has a certain fluidity and will not solidify due to long-term waiting, making the antifoaming agent invalid.
[0034] Such as Figures 1 to 9As shown in the figure, the mobile platform 4 further includes: a sliding groove 41, in which the storage frame 51 slides on the inner wall; a limiting shaft 42, which is arranged at both ends of the tail of the mobile platform 4; a rotating rod 43, which is arranged at both ends of the mobile platform 4, and the rotating rod 43 is rotatably connected to the placing platform 2; the casting structure 3 further includes: a lifting rod 33, which is arranged at the upper end of the lower mold 31, and the upper mold 32 slides on the surface of the lifting rod 33; the adjusting structure 6 further includes: a rotating shaft 603, which is rotatably connected to the inner wall of the base frame 1, and the rotating plate 604 is connected to the rotating shaft 603; a limiting track 605, which is arranged at one end of the surface of the placing platform 2 close to the limiting shaft 42, and the limiting shaft 42 slides on the inner wall of the limiting track 605.
[0035] Specifically, when the mobile platform 4 drives the storage frame 51 to rotate, the mobile platform 4 will rotate around the rotating rod 43 as the axis, and the limiting shaft 42 located at the tail of the mobile platform 4 will also slide on the inner wall of the limiting track 605, so that the rotation angle of the mobile platform 4 is controllable.
[0036] As Figures 1 to 6 shown, a pipeline 610 is arranged at the upper end of the pressing strip 611, a storage agent frame 607 is slidably connected to the upper end of the pipeline 610, and an antifoaming agent is placed inside the storage agent frame 607. The storage agent frame 607 is connected to the rotating plate 604. Liquid passing openings 613 are formed at both the upper and lower ends of the pipeline 610. A compression spring 615 is arranged inside the storage agent frame 607. One end of the compression spring 615 is provided with a sealing ball 614, and in the initial state, the sealing ball 614 blocks the opening at the lower end of the storage agent frame 607, and the sealing ball 614 is in contact with the pipeline 610.
[0037] Specifically, by arranging the storage agent frame 607 on one side of the rotating plate 604, when the pressing strip 611 contacts the casting groove 35, the pipeline 610 at the upper end of the pressing strip 611 will enter the inside of the storage agent frame 607 and contact the sealing ball 614. Subsequently, the sealing ball 614 will move upward, and finally the antifoaming agent inside the storage agent frame 607 can enter the pipeline 610 through the liquid passing opening 613 and flow to the surface of the pressing strip 611, so that the antifoaming agent on the surface of the pressing strip 611 can be automatically replenished after each application. After the application is completed, due to the absence of the pressing force, the compression spring 615 will release its elastic force at this time, and finally the sealing ball 614 will be re-pressed to block the opening at the lower end of the storage agent frame 607 to prevent the antifoaming agent from leaking.
[0038] As Figure 6 shown, a limiting rod 616 is arranged inside the storage agent frame 607, and the compression spring 615 is sleeved on the surface of the limiting rod 616.
[0039] Specifically, by arranging a limiting rod 616 inside the compression spring 615, when the pipeline 610 leaves the agent storage frame 607 and the sealing ball 614 moves back to block the opening at the lower end of the agent storage frame 607, the movement track of the compression spring 615 can be kept straight, thereby avoiding the problem that the movement track of the compression spring 615 is affected by the defoamer inside the agent storage frame 607 and the movement track of the compression spring 615 is changed.
[0040] As Figure 5 shown, an absorption sponge 612 is arranged at the lower end of the pressing strip 611, and the absorption sponge 612 is in contact with the casting groove 35.
[0041] Specifically, by arranging the absorption sponge 612 at the lower end of the pressing strip 611, when the defoamer flows from the pipeline 610 to the surface of the pressing strip 611, the absorption sponge 612 can absorb a part of the defoamer, which can not only ensure that the defoamer will not overflow, but also enable the defoamer to be stored inside the absorption sponge 612, facilitating subsequent pressing and extrusion.
[0042] As Figure 9 shown, a second screw rod 609 is arranged in the middle of the rotating shaft 603, a torsion spring 608 is arranged behind the rotating shaft 603, a threaded ring 622 is arranged at the lower end of the storage frame 51, and the threaded ring 622 slides on the surface of the rotating shaft 603, and the threaded ring 622 is in threaded connection with the second screw rod 609.
[0043] Specifically, by arranging the threaded ring 622 at the lower end of the storage frame 51, when the storage frame 51 moves along the sliding groove 41, the threaded ring 622 will also slide along the surface of the rotating shaft 603, and then the threaded ring 622 will be in threaded connection with the second screw rod 609, thereby automatically driving the rotating plate 604 to rotate. It can not only realize the automatic application of the defoamer, but also when the threaded ring 622 is disengaged from the connection with the second screw rod 609, the torsion spring 608 will also release elastic force to drive the rotating plate 604 to automatically reset. Embodiment 2
[0044] As Figures 1 to 3 shown, compared with Embodiment 1, another implementation manner of the present invention is that a sealing cover 601 is arranged at the upper end of the moving platform 4, and the sealing cover 601 is in contact with the storage frame 51.
[0045] Specifically, by arranging the sealing cover 601 at the upper end of the moving platform 4, when the storage frame 51 moves to the lower end of the sealing cover 601, the sealing cover 601 is started, and the sealing cover 601 will move downward and finally close the upper end of the storage frame 51, which can not only ensure the temperature of the injection liquid inside the storage frame 51, but also avoid the injection liquid splashing from above the storage frame 51 and causing injury to personnel.
[0046] AsFigures 1 to 9 As shown in the figure, a sliding rod 606 is provided on the upper surface of the mobile platform 4, and the sealing cover 601 slides on the surface of the sliding rod 606. A first screw rod 602 is rotatably connected to the upper surface of the mobile platform 4, and the first screw rod 602 is threadedly connected to the sealing cover 601. A first rotating piece 617 is provided at the lower end of the first screw rod 602. A belt 620 is sleeved on the surface of the first rotating piece 617. The other end of the belt 620 is sleeved with a second rotating piece 618. An auxiliary gear 619 is provided at the lower end of the second rotating piece 618. An auxiliary rack 621 is provided at one end of the threaded ring 622. The auxiliary rack 621 is threadedly connected to the auxiliary gear 619.
[0047] Specifically, when the storage frame 51 moves along the sliding groove 41, the auxiliary rack 621 at one end of the threaded ring 622 will also move together. Eventually, the auxiliary rack 621 will contact the auxiliary gear 619 and drive the auxiliary gear 619 to rotate. The second rotating piece 618 located above the auxiliary gear 619 will also drive the first screw rod 602 to rotate through the belt 620. Since the first screw rod 602 is threadedly connected to the sealing cover 601 and the other end of the sealing cover 601 slides on the surface of the sliding rod 606, the sealing cover 601 will also move downward at this time, thereby automatically closing the upper end of the storage frame 51.
[0048] As Figure 8 shown, two flow-limiting plates 53 are slidably connected inside the discharge port 52, and the flow-limiting plates 53 are in contact with the injection molding liquid.
[0049] Specifically, by providing two flow-limiting plates 53 inside the discharge port 52, when dealing with the upper mold 31 and the lower mold 32 with different heights, the flow-limiting plates 53 can be activated to adjust the positions of the two flow-limiting plates 53, thereby controlling the flow rate and velocity of the injection molding liquid being poured out, so that when the injection molding liquid is transferred, it can be poured into the casting port 34 smoothly and accurately, avoiding overflow or splashing.
[0050] As Figure 8 shown, a driving gear 54 is rotatably connected to the lower end of the discharge port 52. A fixed rack 55 is provided at the lower end of the flow-limiting plate 53, and the fixed rack 55 meshes with the driving gear 54.
[0051] Specifically, when it is necessary to adjust the positions of the two flow-limiting plates 53, only need to start the driving gear 54 to rotate, and the driving gear 54 can drive the engaged fixed rack 55 to move, thereby adjusting the positions of the two flow-limiting plates 53.
[0052] Working principle: Before casting, high-quality pig iron, scrap steel, alloy additives, and silicon elements are first selected as raw materials. Subsequently, the raw materials are put into the storage frame 51 in a certain proportion for melting. By adjusting the internal temperature of the storage frame 51, it is ensured that the materials are melted into molten iron and impurities are effectively removed. And this molten iron is the injection liquid. A spheroidizing agent, such as heavy magnesium and light ferroalloy, is added to the molten iron to form spherical graphite, so as to improve the fracture performance and plasticity. Subsequently, the storage frame 51 and the molten iron inside it are kept warm for a period of time to make elements such as silicon dissolve evenly in the iron matrix, completing the solution treatment. At this time, the supersaturated precipitates are eliminated, the hardness and strength are improved, and the wear resistance of the subsequent cast iron can be enhanced, making it perform better in aspects such as friction wear and impact wear. After the solution treatment is completed, the storage frame 51 is started, and the storage frame 51 will slide along the surface of the moving platform 4. When the storage frame 51 moves along the sliding groove 41, the threaded ring 622 will also slide along the surface of the rotating shaft 603. Subsequently, the threaded ring 622 will be threadedly connected with the second screw rod 609, thereby automatically driving the rotating plate 604 to rotate. The rotating plate 604 will drive the pressing strip 611 to contact the casting groove 35. When the pressing strip 611 contacts the casting groove 35, the pipe 610 at the upper end of the pressing strip 611 will enter the interior of the agent storage frame 607 and contact the sealing ball 614. Subsequently, the sealing ball 614 will move upward, and finally the defoaming agent inside the agent storage frame 607 can enter the pipe 610 through the liquid passing port 613, flow to the surface of the pressing strip 611, and finally evenly coat the inner wall of the casting groove 35 with the defoaming agent. These defoaming agents can improve the distribution of the injection liquid on the mold surface and enhance its fluidity. This improvement helps the injection liquid to fill the mold more evenly and reduces the generation of bubbles. When the threaded ring 622 disengages from the connection with the second screw rod 609, the coil spring 608 will also release its elastic force, driving the rotating plate 604 to automatically reset. And when the storage frame 51 moves along the sliding groove 41, the auxiliary rack 621 at one end of the threaded ring 622 will also move together. Finally, the auxiliary rack 621 will contact the auxiliary gear 619 and drive the auxiliary gear 619 to rotate. The second rotating piece 618 located above the auxiliary gear 619 will also drive the first screw rod 602 to rotate through the belt 620. Since the first screw rod 602 is threadedly connected with the sealing cover 601 and the other end of the sealing cover 601 slides on the surface of the sliding rod 606, the sealing cover 601 will also move downward at this time, thereby automatically closing the upper end of the storage frame 51. At this time, the upper mold 32 is started, and the upper mold 32 will move downward and finally contact the lower mold 31. At this time, the moving platform 4 is started, and the moving platform 4 will rotate along the surface of the placement platform 2. Finally, the injection liquid inside the storage frame 51 can flow into the casting port 34 through the discharge port 52 and finally into the casting groove 35 to complete the casting.
