Description

Technical Field

[0001] The invention belongs to the technical field of ductile iron, in particular to a high-silicon solid solution strengthened ductile iron casting device. Background Art

[0002] Ductile iron is a high-strength cast iron material with comprehensive properties close to those of steel. Based on its excellent properties, it has been successfully used to cast some parts with complex stresses and high requirements for strength, toughness and wear resistance. The casting is carried out by pouring, and rare earth magnesium alloy is used as a spheroidizer during the casting process. The graphite is formed into spheres through chemical reactions, thereby improving the toughness and strength of the cast iron.

[0003] A patent application with publication number CN216327560U discloses a casting device for preparing high-silicon solid solution strengthened ductile iron, including a fixed frame, on which ductile iron is arranged, an inner clamping mechanism is arranged on the fixed frame, and the inner clamping mechanism can clamp the ductile iron, and an upper sleeve mechanism capable of adjusting the clamping state of the inner clamping mechanism is provided on the fixed frame. When the inner baffle plate moves upward, the spring 1 will gradually restore its deformation. When the spring 1 restores its deformation, the fixed rod remains stationary, and the upper locking sleeve will leave the four clamping plates. At the same time, the spring 2 expands the clamping plates through its own elastic force, and the clamping plates rotate and open to leave the ductile iron. When the fixed rod moves upward, the four clamping plates will automatically reset without manual operation, which further improves the convenience of operation.

[0004] There are still some problems in the actual application of the above scheme. During the smelting process, if the casting speed is too fast, a large amount of gas, such as hydrogen, oxygen and nitrogen, may be generated. The metal liquid may absorb a large amount of gas. If these gases are not fully discharged during the casting process, bubbles will be formed. These bubbles will affect the appearance of the casting. In order to solve this problem, the prior art will apply a defoaming agent on the mold before casting to prevent the generation of bubbles. However, when the defoaming agent is applied to the mold, since the casting equipment and the mold are integrated, the mold cannot be taken separately. When the defoaming agent is applied to the mold, the high-temperature injection molding liquid in the casting equipment will transmit the 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 defoaming agent. Therefore, the operator can only apply the defoaming agent to the mold before the injection molding liquid is made. However, after the casting is demolded, the next casting needs to be produced in time. The above-mentioned application method cannot be performed during the cycle casting.

[0005] To this end, the present invention provides a high-silicon solid solution strengthened spheroidal graphite casting device. Summary of the invention

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0022] like Figures 1 to 9As shown, a high-silicon solid solution strengthened ductile iron casting device according to an embodiment of the present invention comprises a base frame 1, a placing platform 2 is arranged at the upper end of the base frame 1, a mobile platform 4 is rotatably connected to the surface of the placing platform 2, a storage structure 5 is arranged on the surface of the mobile platform 4, a casting structure 3 is arranged at one end of the upper end of the base frame 1 close to the placing platform 2, and an adjustment structure 6 is arranged on the surface of the casting structure 3; the storage structure 5 comprises: a storage frame 51, the storage frame 51 is slidably connected to the surface of the mobile platform 4; a discharge port 52, the discharge port 52 is arranged at the storage frame 51 one end; the casting structure 3 includes: a lower mold 31, the lower mold 31 is arranged 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 bar 611, the pressing bar 611 is arranged at one end of the rotating plate 604, and the pressing bar 611 is in contact with the casting groove 35.

[0023] Specifically, a high-silicon solid solution strengthened ductile iron casting device of the scheme first selects high-quality pig iron, scrap steel, alloy additives and silicon elements as raw materials before casting, and then puts the raw materials into the storage frame 51 for smelting in a certain proportion, and adjusts the internal temperature of the storage frame 51 to ensure that the material is melted into molten iron and impurities are effectively removed, and the molten iron is an injection liquid, and a spheroidizing agent, such as heavy magnesium and light iron alloy, is added to the molten iron to form spheroidal graphite to improve fracture performance and plasticity, and then the storage frame 51 and the molten iron inside it are kept warm for a period of time to make elements such as silicon evenly dissolved in the iron matrix to complete the solid solution treatment. At this time, the supersaturated precipitates are eliminated, the hardness and strength are improved, and it can Improve the wear resistance of subsequent cast iron, so that it performs better in terms of friction wear and impact wear. After the solution treatment is completed, start the storage frame 51, and the storage frame 51 will slide along the surface of the mobile platform 4. Then, when the storage frame 51 moves to one end close to the upper mold 32, start the upper mold 32, and the upper mold 32 will move downward and finally contact with the lower mold 31. At this time, start the mobile platform 4, and the mobile platform 4 will rotate along the surface of the placement platform 2, so that 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 trough 35 to complete the casting. However, if the casting speed is too fast, a large amount of gas may be generated. The metal liquid may absorb a large amount of gas, such as hydrogen, oxygen and nitrogen. If these gases are not fully discharged during the casting process, bubbles will form. These bubbles, as air bags, will cause pores on the surface of the casting. Its strength is much lower than that of iron materials 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 purpose, an adjustment structure 6 is designed. When the storage frame 51 moves toward the upper mold 32, the rotating plate 604 is started, and the rotating plate 604 will drive the pressing bar 611 to rotate. The surface of the pressing bar 611 is coated with a defoaming agent. The pressing bar 611 will eventually contact the inner wall of the casting trough 35 and evenly spread the defoaming agent. The defoaming agents are applied to the inner wall of the casting groove 35. These defoaming agents can improve the distribution of the injection liquid on the mold surface and improve its fluidity. This improvement helps the injection liquid to fill the mold more evenly and reduce the generation of bubbles. Then, when the upper mold 32 moves downward, the rotating plate 604 is started again. The rotating plate 604 will drive the pressing bar 611 to reset. After the rotating plate 604 is reset, the upper mold 32 and the lower mold 31 are also fitted. At this time, when the injection liquid enters the interior of the casting groove 35, the defoaming agent on the inner wall of the casting groove 35 will prevent pores from forming on the surface of the casting. The defoaming agent also has a certain fluidity and will not solidify due to long waiting, making the defoaming agent invalid.

[0024] like Figures 1 to 9As shown, the mobile platform 4 also includes: a sliding groove 41, and the storage frame 51 slides on the inner wall of the sliding groove 41; a limiting shaft 42, and the limiting shaft 42 is arranged at both ends of the tail of the mobile platform 4; a rotating rod 43, and the rotating rod 43 is arranged at both ends of the mobile platform 4, and the rotating rod 43 is rotatably connected to the placement platform 2; the casting structure 3 also includes: a lifting rod 33, and the lifting rod 33 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 adjustment structure 6 also includes: a rotating shaft 603, and the rotating shaft 603 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, and the limiting track 605 is arranged on one end of the surface of the placement platform 2 close to the limiting shaft 42, and the limiting shaft 42 slides on the inner wall of the limiting track 605.

[0025] Specifically, when the mobile platform 4 drives the storage frame 51 to rotate, the mobile platform 4 will rotate around the rotating rod 43, 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.

[0026] like Figures 1 to 6 As shown, a pipe 610 is provided at the upper end of the pressing strip 611, and a storage frame 607 is slidably connected to the upper end of the pipe 610, and a defoaming agent is placed inside the storage frame 607, and the storage frame 607 is connected to the rotating plate 604. Liquid passages 613 are provided at the upper and lower ends of the pipe 610, and a compression spring 615 is provided inside the storage frame 607. A sealing ball 614 is provided at one end of the compression spring 615, and the sealing ball 614 blocks the opening at the lower end of the storage frame 607 in the initial state, and the sealing ball 614 is in contact with the pipe 610.

[0027] Specifically, by setting a storage frame 607 on one side of the rotating plate 604, 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 storage frame 607 and contact the sealing ball 614, and then the sealing ball 614 will move upward, so that the defoaming agent in the storage frame 607 can enter the pipe 610 through the liquid port 613 and flow to the surface of the pressing strip 611, so that the defoaming agent on the surface of the pressing strip 611 can be automatically replenished after each application. After the application is completed, since there is no pressing pressure, the compression spring 615 will release the elastic force, and finally the sealing ball 614 will be squeezed again to block the opening at the lower end of the storage frame 607 to prevent the defoaming agent from leaking.

[0028] like Figure 6 As shown, a limiting rod 616 is provided inside the agent storage frame 607 , and a compression spring 615 is sleeved on the surface of the limiting rod 616 .

[0029] Specifically, by setting a limit rod 616 inside the compression spring 615, when the pipeline 610 leaves the storage frame 607 and the sealing ball 614 moves again to block the opening at the lower end of the storage frame 607, the moving trajectory of the compression spring 615 can remain straight, thereby preventing the compression spring 615 from being affected by the defoaming agent inside the storage frame 607, causing the moving trajectory of the compression spring 615 to change.

[0030] like Figure 5 As shown, an absorption sponge 612 is provided at the lower end of the pressing strip 611 , and the absorption sponge 612 is in contact with the casting groove 35 .

[0031] Specifically, by setting an absorbent sponge 612 at the lower end of the pressing strip 611, the absorbent sponge 612 can absorb a portion of the defoaming agent when the defoaming agent flows from the pipe 610 to the surface of the pressing strip 611, which can not only ensure that the defoaming agent does not overflow, but also allow the defoaming agent to be stored inside the absorbent sponge 612, which is convenient for subsequent pressing and squeezing.

[0032] like Fig. 9 As shown, a second screw 609 is provided in the middle of the rotating shaft 603, a coil spring 608 is provided behind the rotating shaft 603, a threaded ring 622 is provided 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 threadedly connected to the second screw 609.

[0033] Specifically, by setting a 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 threadedly connected with the second screw 609, thereby automatically driving the rotating plate 604 to rotate, which can not only realize the automatic application of the defoaming agent, but also when the threaded ring 622 is disconnected from the second screw 609, the coil spring 608 will also release the elastic force, driving the rotating plate 604 to automatically reset. Embodiment 2

[0034] like Figures 1 to 3 As shown, in contrast to Example 1, another implementation of the present invention is that a sealing cover 601 is provided at the upper end of the mobile platform 4 , and the sealing cover 601 is in contact with the storage frame 51 .

[0035] Specifically, by setting a sealing cover 601 at the upper end of the movable 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 to finally seal the upper end of the storage frame 51, thereby ensuring the temperature of the injection molding liquid inside the storage frame 51 and preventing the injection molding liquid from splashing out from the top of the storage frame 51 to cause personal injury.

[0036] like Figures 1 to 9 As shown, a sliding rod 606 is provided on the upper surface of the mobile platform 4, and a sealing cover 601 slides on the surface of the sliding rod 606. A first screw 602 is rotatably connected to the upper surface of the mobile platform 4, and the first screw 602 is threadedly connected to the sealing cover 601. A first rotating piece 617 is provided at the lower end of the first screw 602. A belt 620 is sleeved on the surface of the first rotating piece 617. A second rotating piece 618 is sleeved on the other end of the belt 620. 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.

[0037] 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, and 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 602 to rotate through the belt 620. Since the first screw 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.

[0038] like Figure 8 As 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 liquid.

[0039] Specifically, by setting two flow limiting plates 53 inside the discharge port 52, when dealing with the upper mold 31 and the lower mold 32 of different heights, the flow limiting plates 53 can be started to adjust the positions of the two flow limiting plates 53, thereby controlling the flow rate and flow velocity of the injection liquid, so that when the injection liquid is transferred, it can be poured into the casting port 34 smoothly and accurately to avoid overflow or splashing.

[0040] like Figure 8 As shown, the lower end of the discharge port 52 is rotatably connected to a driving gear 54 , and the lower end of the flow limiting plate 53 is provided with a fixed rack 55 , and the fixed rack 55 is meshed with the driving gear 54 .

[0041] Specifically, when the positions of the two flow limiting plates 53 need to be adjusted, the driving gear 54 only needs to be started to rotate, and the driving gear 54 can drive the meshing fixed rack 55 to move, thereby adjusting the positions of the two flow limiting plates 53 .

[0042] Working principle: Before casting, high-quality pig iron, scrap steel, alloy additives and silicon elements are first selected as raw materials, and then the raw materials are put into the storage frame 51 for smelting in a certain proportion. By adjusting the internal temperature of the storage frame 51, it is ensured that the material is melted into molten iron and impurities are effectively removed. The molten iron is an injection liquid. A spheroidizing agent, such as heavy magnesium and light iron alloy, is added to the molten iron to form spheroidal graphite to improve the fracture performance and plasticity. Then the storage frame 51 and the molten iron inside it are kept warm for a period of time to make elements such as silicon evenly dissolved in the iron matrix to complete the solid 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 improved, making it more resistant to friction wear and impact wear. The storage frame 51 performs better in this aspect. 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, and then the threaded ring 622 will be threadedly connected with the second screw 609, thereby automatically driving the rotating plate 604 to rotate, and the rotating plate 604 will drive the pressing bar 611 to contact the casting groove 35. When the pressing bar 611 contacts the casting groove 35, the pipe 610 at the upper end of the pressing bar 611 will enter the interior of the storage frame 607 and contact the sealing ball 614. Then the sealing ball 614 will move upward, and finally the storage frame 607 will be sealed. The defoaming agent in the outside can enter the pipeline 610 through the liquid outlet 613 and flow to the surface of the pressing strip 611, and finally the defoaming agent is evenly applied to the inner wall of the casting groove 35. These defoaming agents can improve the distribution of the injection liquid on the mold surface and improve its fluidity. This improvement helps the injection liquid to fill the mold more evenly and reduce the generation of bubbles. When the threaded ring 622 is disconnected from the second screw 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, and 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 602 to rotate through the belt 620. Since the first screw 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. At this time, the upper mold 32 is started, and the upper mold 32 will move downward and finally contact with the lower mold 31. At this time, the mobile platform 4 is started, and the mobile platform 4 will rotate along the surface of the placement platform 2, so that 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 trough 35 to complete the casting.
