Description

[0041] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0042] The present invention provides a casting system, which is mainly used for alloy casting. Alloy casting is a molding process in which molten metal is poured into a mold cavity and then cooled and solidified to obtain a casting of a desired shape.
[0043] The casting system includes an iron casting machine and a casting trolley. The casting trolley includes an iron mold and a running mechanism. The running mechanism is arranged at the bottom of the iron mold, and the running mechanism can drive the iron mold to move back and forth along the track of the iron casting machine. For example, the running mechanism may include running wheels, etc. The coordination of the running wheels with the track of the iron casting machine, and the source of the driving force for the running wheels to move on the track can be determined according to the structure of the existing iron casting machine, and will not be repeated in the embodiments of this application. The embodiments of this application do not impose any restrictions on the running mechanism, and the running mechanism can be adaptively selected according to actual needs.
[0044] An iron mold is a metal casting mold made of heat-resistant alloy steel. Its top surface (the side facing away from the casting machine) features a cavity recessed toward the casting machine. The shape of the cavity matches (is identical to or similar to) the shape of the casting. A casting machine is a complete set of casting equipment, including the track system, drive unit, and pouring station.
[0045] The casting system usually also has a casting mechanism, which can be set above the casting station of the cast iron machine to cast the iron mold in the casting trolley moving along the track. It can also be used in other metal forming equipment that requires casting.
[0046] The following mainly describes the structure of the casting system by taking the application scenario where the casting mechanism is set on a cast iron machine as an example.
[0047] In the alloy casting process, molten iron is poured into an iron mold through a runner on a casting mechanism to form a casting. The formed molten iron forms a casting.
[0048] It should be noted that the molten iron is poured onto the iron mold through the runner, which means that the molten iron is poured into the mold cavity of the iron mold through the runner. If there are expressions similar to "cast on the iron mold" in the following text, this can be understood and will not be repeated in the following text.
[0049] However, in traditional casting systems, the runner is typically fixed above the casting station. When the mold is moved to the casting position, molten iron is continuously poured from the gate into the same area of the mold. Because the pouring position remains fixed, the high-temperature molten iron continuously concentrates on the same area of the mold. This not only causes overheating and corrosion in that area, shortening the mold's service life, but also leads to uneven distribution of the molten iron within the mold cavity, affecting the molding quality and mechanical properties of the casting.
[0050] In view of this, the present embodiment provides a casting system, which includes a mobile casting mechanism, and the mobile casting mechanism includes a runner and a driving device. The runner has a casting trough, and the casting trough has a casting mouth, and the casting mouth is used to cast molten iron onto the iron mold of the iron casting machine. The driving device includes a motor, a first transmission member and a second transmission member, and the output end of the motor is connected to the first transmission member. The second transmission member has a first end and a second end in the length direction, the first end is movably connected to the first transmission member, and the second end is movably connected to the runner. The first casting transmission member is constructed to rotate under the drive of the motor and drive the second transmission member to move, so as to drive the end of the runner with the casting mouth to swing relative to the iron mold through the second transmission member, so that during the casting process, the position of the casting mouth can continuously change relative to the iron mold, thereby avoiding the molten iron from concentrating on the same position of the iron mold for a long time, thereby effectively preventing local overheating and erosion of the iron mold and extending the service life of the iron mold.
[0051] Figure 1 2 is a structural diagram of the mobile casting mechanism 100 provided in this application, Figure 1 A schematic structural diagram of the runner 1 of the movable casting mechanism 100 near the first edge 201, Figure 5 for Figure 1 The structural diagram of the driving device 2 is shown below. Figure 1 、 Figure 2 and Figure 5 , the structure of the mobile casting mechanism 100 provided in this embodiment is further explained.
[0052] See also Figure 1 、 Figure 2 and Figure 5 The present embodiment provides a casting system, which includes a mobile casting mechanism 100. The mobile casting mechanism 100 includes a runner 1 having a casting trough 11. The casting trough 11 has a casting port 12 for casting molten iron onto an iron mold 200 of an iron casting machine 300.
[0053] Specifically, in this embodiment, the runner 1 is made of high-temperature resistant material, and a casting trough 11 is opened inside the runner 1. The casting trough 11 is used to guide the flow of molten iron. A casting port 12 is opened at the bottom of the casting trough 11. After the molten iron flows through the casting trough 11, it flows into the iron mold 200 through the casting port 12.
[0054] Among them, a cavity is provided inside the iron mold 200, and the cavity is matched with the shape of the casting. Molten iron flows into the cavity from the casting port 12. As the molten iron gradually fills the cavity, its heat is absorbed by the iron mold 200 and begins to solidify layer by layer from the outside to the inside. After sufficient cooling and solidification, the iron mold 200 is opened to obtain a casting consistent with the shape of the cavity.
[0055] The specific shape and structure of the mold cavity can be adaptively adjusted according to the required casting, and this embodiment does not impose any restrictions on this. For example, the mold cavity can be a rectangular structure, etc., so as to form molten iron into iron blocks or other alloy blocks.
[0056] See also Figure 1 、 Figure 2 and Figure 5 The mobile casting mechanism 100 also includes a driving device 2, which includes a motor 21, a first transmission member 22 and a second transmission member 23. The output end of the motor 21 is connected to the first transmission member 22; the second transmission member 23 has a first end 231 and a second end 232 in the length direction, the first end 231 is movably connected to the first transmission member 22, and the second end 232 is movably connected to the runner 1; the first transmission member 22 is configured to rotate under the drive of the motor 21 and drive the second transmission member 23 to move, so as to drive the end of the runner 1 having the casting port 12 to swing relative to the iron mold 200 through the second transmission member 23, so that the rotational motion of the first transmission member 22 can be converted into the reciprocating motion of the second transmission member 23, thereby driving the runner 1 to achieve periodic swing, thereby enabling the position of the casting port 12 relative to the iron mold 200 to be continuously changed, thereby preventing the molten iron from concentrating on the same position of the iron mold 200, effectively preventing the iron mold 200 from having local overheating and erosion problems, and extending the service life of the iron mold 200.
[0057] In addition, the continuous swing of the casting nozzle 12 enables the molten iron to form a uniform flow filling mode in the mold cavity, avoiding the problem of local accumulation of molten iron caused by fixed-point casting, ensuring that all parts of the casting begin to solidify at the same time, and reducing the internal stress of the casting.
[0058] Specifically, in some embodiments, the first transmission member 22 may be a crankshaft, and the second transmission member 23 may be a connecting rod, and the rotational motion of the crankshaft is converted into the swinging motion of the runner 1 through the connecting rod.
[0059] In other embodiments, the first transmission member 22 may be a cam, and the second transmission member 23 may be a driven rod, and the profile of the cam pushes the driven rod to drive the runner 1 to swing.
[0060] In another exemplary embodiment, the first transmission member 22 may be an eccentric wheel, and the second transmission member 23 may be a connecting rod, and the eccentric motion of the eccentric wheel is converted into the swinging motion of the runner 1 through the connecting rod.
[0061] At the same time, it should be noted that since the rotation speed of the motor 21 itself is relatively high, and the swing of the runner 1 requires a relatively slow speed to ensure the casting quality, a reducer can also be provided between the motor 21 and the first transmission member 22 to convert the high-speed rotation of the motor 21 into a low-speed output suitable for the swing of the runner 1.
[0062] See also Figure 1 、 Figure 2 and Figure 5 In some embodiments, the first transmission member 22 includes a rotating member having a first connecting portion 221 and a second connecting portion 222 , the output end of the motor 21 is connected to the first connecting portion 221 , and the first end 231 is rotatably connected to the second connecting portion 222 .
[0063] Specifically, in this embodiment, the first transmission member 22 includes a rotating member having a disc-like structure. The rotating member is connected to the output end of the motor 21 via a first connecting portion 221, ensuring effective transmission of the torque of the motor 21. The second connecting portion 222 is spaced apart from the first connecting portion 221, and the second connecting portion 222 follows the rotating member in circular motion. When the rotating member rotates under the drive of the motor 21, the rotation of the rotating member causes the second connecting portion 222 to move in a circular trajectory. The circular trajectory motion is constrained by the second transmission member 23, which can force the runner 1 to swing back and forth around its fixed fulcrum within a certain angle range, thereby converting the continuous rotational motion of the rotating member into the periodic swinging motion of the runner 1.
[0064] See also Figure 5 In this embodiment, the first connecting portion 221 is a boss structure, and a mounting hole matching the output shaft of the motor 21 is processed in the center of the boss structure. A keyway is provided in the mounting hole, so that the output shaft of the motor 21 is axially fixed through a key connection to ensure effective transmission of torque.
[0065] The keyway may be a spline slot or a flat keyway, and this embodiment does not impose any limitation on this.
[0066] In this embodiment, the second connecting portion 222 is a groove, and the first end 231 of the second transmission member 23 has a protrusion matching the groove. The second transmission member 23 is connected to the first transmission member 22 by snapping the protrusion into the groove.
[0067] See also Figure 1 、 Figure 2 and Figure 5 In some embodiments, the first connection portion 221 is located at the center of the rotating member, and the second connection portion 222 is located at the center of the rotating member on one side close to the circumferential edge of the rotating member.
[0068] Specifically, since the first connecting part 221 is located at the center of the rotating part, the motor 21 is connected to the center of the rotating part, which can ensure the stability of the rotating part when the motor 21 drives the rotating part to rotate. Since the second connecting part 222 is located on the side of the center of the rotating part close to the circumferential edge of the rotating part, when the motor 21 drives the rotating part to rotate, since the second connecting part 222 is not at the center of the rotating part, the first end 231 of the second transmission member 23 will make a circular motion around the center of the rotating part, and the circular motion is transmitted to the runner 1 through the second end 232 of the second transmission member 23. Since the other end of the second transmission member 23 is movably connected to the runner 1, the circular motion of the second connecting part 222 can be converted into reciprocating swinging of the runner 1.
[0069] For example, when the second connection portion 222 rotates to the top of the rotating member, the second transmission member 23 can push the runner 1 to swing upward; when the second connection portion 222 rotates to the bottom of the rotating member, the second transmission member 23 can pull the runner 1 to swing downward.
[0070] See also Figure 1 、 Figure 2 and Figure 5 In some embodiments, one of the first end 231 and the second connecting portion 222 has a protruding connecting shaft 2311, and the other has a first connecting hole at a position corresponding to the connecting shaft 2311, and the connecting shaft 2311 is inserted into the first connecting hole.
[0071] Specifically, the second transmission member 23 and the first transmission member 22 are movably connected between the first end 231 and the second connecting portion 222 through the connecting shaft 2311 and the first connecting hole, so that the second transmission member 23 can rotate relative to the first transmission member 22, and at the same time ensure that when the motor 21 drives the rotating member to rotate, the connecting shaft 2311 can reliably push the second transmission member 23 to move.
[0072] In this embodiment, the first end 231 has a connecting shaft 2311, and the second connecting portion 222 has a first connecting hole at a position corresponding to the connecting shaft 2311. By passing the connecting shaft 2311 through the first connecting hole, the second transmission member 23 and the first transmission member 22 are movably connected.
[0073] In another embodiment, the second connecting portion 222 has a connecting shaft 2311, and the first end 231 has a first connecting hole at a position corresponding to the connecting shaft 2311. By passing the connecting shaft 2311 through the first connecting hole, the second transmission member 23 and the first transmission member 22 are movably connected.
[0074] See also Figure 2 and Figure 5 In some embodiments, the motor 21 comprises a variable frequency motor. A variable frequency motor can control the frequency of the input power supply via a frequency converter, thereby precisely adjusting the speed of the motor 21. The speed of the motor 21 is proportional to the power supply frequency; higher frequencies result in faster speeds, while lower frequencies result in slower speeds.
[0075] By setting the motor 21 as a variable frequency motor in this embodiment, the operator can adjust the speed of the motor 21 in real time according to the specific requirements of different castings. For example, when casting large castings, the speed of the motor 21 can be reduced, and the runner 1 can be swung slowly, so that the molten iron can fully fill all parts of the mold cavity and avoid insufficient pouring. When casting small precision castings, the speed of the motor 21 can be appropriately increased, and the swing frequency of the runner 1 can be accelerated to ensure that the molten iron can evenly flow into all small parts of the mold cavity and ensure the molding quality of the casting. Furthermore, by setting the variable frequency motor, the casting process can be more flexibly adapted to the production needs of castings of different sizes and structures.
[0076] Figure 3 for Figure 1 The schematic diagram of the structure of the movable casting mechanism 100 in which the runner 1 is located at the center of the iron mold 200 is shown. Figure 4 for Figure 1 Schematic diagram of the structure of the runner 1 of the movable casting mechanism 100 close to the second edge 202.
[0077] See also Figures 2 to 4In some embodiments, the iron mold 200 has a first edge 201 and a second edge 202 relative to each other in the width direction x; along the width direction x of the iron mold 200: one end of the runner 1 having the casting port 12 is configured to swing from the position of one of the first edge 201 and the second edge 202 to the position of the other under the drive of the second transmission member 23; or, along the width direction x of the iron mold 200: one end of the runner 1 having the casting port 12 is configured to swing from the center of the iron mold 200 in the width direction x to the position of the first edge 201 or the second edge 202 under the drive of the second transmission member 23.
[0078] Specifically, in this embodiment, the iron mold 200 has a first edge 201 and a second edge 202 disposed opposite each other in the width direction x. These two edges correspond to the left and right boundary positions of the iron mold 200, respectively. The first edge 201 serves as the left limit boundary of the iron mold 200, and the second edge 202 serves as the right limit boundary. The area between the first edge 201 and the second edge 202 constitutes the effective casting area of the iron mold 200. If the pouring nozzle 12 extends beyond the first edge 201 or the second edge 202, molten iron will overflow outside the iron mold 200, resulting in material waste and safety hazards.
[0079] Driven by the drive device 2, the runner 1 in this embodiment can swing from the first edge 201, passing through the center of the iron mold 200, and then reaching the second edge 202, completing a complete swing stroke. This ensures that the molten iron evenly covers the entire width of the iron mold 200, ensuring the best possible casting quality. Simultaneously, the continuous swinging of the pouring nozzle 12 creates a wave-like filling pattern for the molten iron within the mold cavity, avoiding the problem of localized accumulation of molten iron caused by fixed-point casting. This ensures that all parts of the casting begin solidifying simultaneously, reducing internal stress in the casting.
[0080] Specifically, in this embodiment, the swing amplitude of the runner 1 is 10°, the swing distance is 418 mm, the second connecting portion 222 performs a circular motion around the center of the rotating member, and the diameter of the circular motion is 235 mm. Since the runner 1 swings under the drive of the second transmission member 23, when the runner 1 swings to the first edge 201 and to the second edge 202, the relative distance between the two extreme positions along the width direction x of the iron mold 200 is equal to the diameter of the circular motion.
[0081] It is defined that when the second connection part 222 makes a circular motion driven by the rotating part, the extreme position close to the runner 1 is point B1, and the extreme position away from the runner 1 is point B3. When the runner 1 is located at the center of the iron mold 200 in the width direction x, the second connection part 222 can be located on both sides of the rotating part along the width direction x of the iron mold 200. When it is located on the left side, the position of the second connection part is point B2, and when it is located on the right side, the position of the second connection part is point B4.
[0082] See also Figures 2 to 4 In combination with the above data, the following specifically describes the movement process of the runner 1 driven by the driving device 2, starting from the first edge 201 position, passing through the center area of the iron mold 200 and reaching the second edge 202 position.
[0083] First, in this embodiment, the initial position of runner 1 is at first edge 201, with the second connection portion at point B1. The rotating member rotates counterclockwise, causing the second connection portion 222 to rotate from point B1 to point B2. At this point, the second transmission member 23 rotates 87.41°, and runner 1 swings 5° to the center of the iron mold 200 in the width direction x.
[0084] When the runner 1 swings to the center of the iron mold 200 in the width direction x, the rotating member continues to rotate counterclockwise, causing the second connecting portion 222 to rotate from point B2 to point B3. At this time, the second transmission member 23 rotates 92.59°, and the runner 1 swings 5° to the second edge 202.
[0085] When the runner 1 swings to the second edge 202, the rotating member continues to rotate counterclockwise, causing the second connecting portion 222 to rotate from point B3 to point B4. At this time, the second transmission member 23 rotates 92.59°, and the runner 1 swings 5° to the center of the iron mold 200 in the width direction x.
[0086] After the runner 1 swings to the center of the iron mold 200 in the width direction x, the rotating part continues to rotate counterclockwise, causing the second connecting portion 222 to rotate from point B4 to point B1. At this time, the second transmission member 23 rotates 87.41°, and the runner 1 swings 5° to be located at the first edge 201, thereby completing the complete movement process.
[0087] It should be noted that the above embodiment is merely an example of the swing amplitude and distance of the runner 1 and the specific dimensions of the rotating member. The swing amplitude and distance of the runner 1 and the specific dimensions of the rotating member can be adaptively selected according to actual needs, and this embodiment does not impose any restrictions on this.
[0088] In another embodiment, the runner 1 can swing from the center of the iron mold 200 in the width direction x under the drive of the driving device 2, swing to the first edge 201, and then pass through the central area of the iron mold 200 to reach the second edge 202, forming a complete swing stroke, or swing to the second edge 202, and then pass through the central area of the iron mold 200 to reach the first edge 201, forming a complete swing stroke. In this regard, the swing starting point of the runner 1 can be adaptively selected according to actual needs, and this embodiment does not impose any restrictions.
[0089] See also Figures 1 to 5In some embodiments, when one end of the runner 1 having the pouring port 12 swings to the position of the first edge 201 or the second edge 202, the projection of the pouring port 12 on the iron mold 200 does not exceed the outermost edge of the iron mold 200, so that the molten iron can be completely introduced into the effective casting area of the iron mold 200, avoiding material waste and safety hazards caused by molten iron overflow, and at the same time ensuring that the edge of the iron mold 200 will not be directly washed by the molten iron, thereby extending the service life of the iron mold 200.
[0090] Specifically, the outermost edge is the first edge 201 or the second edge 202 , that is, during the swinging of the runner 1 , the projection of the pouring port 12 on the iron mold 200 will not exceed the first edge 201 and the second edge 202 to avoid overflow of molten iron.
[0091] Specifically, the swing range of the runner 1 is determined by the rotational speed and rotational radius of the rotating member. The faster the rotational speed, the greater the distance the pouring nozzle 12 swings per unit time; the larger the radius, the wider the swing range of the pouring nozzle 12. Therefore, to ensure that the projection of the pouring nozzle 12 always remains within the effective casting area of the iron mold 200, the rotational speed and radius of the rotating member can be limited based on the width of the iron mold 200, ensuring that the swing range of the pouring nozzle 12 and the iron mold 200 do not extend beyond the first edge 201 and the second edge 202.
[0092] In other embodiments, a limiting mechanism (not shown in the figures) may be provided in the driving device 2 to limit the maximum swing angle of the second transmission member 23, so as to prevent the projection of the casting gate 12 on the iron mold 200 from exceeding the outermost edge of the iron mold 200 when the end of the runner 1 having the casting gate 12 swings to the first edge 201 or the second edge 202. Alternatively, the specific dimensions of the first transmission member 22 and the second transmission member 23 may be adjusted to ensure that the projection of the casting gate 12 on the iron mold 200 does not exceed the outermost edge of the iron mold 200.
[0093] For example, the limiting mechanism may include a mechanical stopper that cooperates with the second transmission member 23 to limit the maximum swing angle of the second transmission member 23. Specifically, when the second transmission member 23 swings to a set maximum angle, the mechanical stopper abuts against the second transmission member 23 to prevent further swinging of the second transmission member 23, thereby ensuring that the projection of the pouring nozzle 12 does not extend beyond the outermost edge of the iron mold 200.
[0094] In another exemplary embodiment, the limiting mechanism may include a sensor. The sensor may include an angle sensor or a position sensor. The sensor may be installed on the runner 1 , and the sensor is used to monitor the swing position of the second transmission member 23 in real time.
[0095] The mobile casting mechanism 100 also includes a processor that is communicatively connected to the sensor and the motor 21 in the drive device 2, respectively. This allows the sensor to transmit monitored information to the processor, and the processor to control the speed and start and stop of the motor 21 based on the information monitored by the sensor, thereby adjusting the swing position of the second transmission member 23. For example, the communication connection method may include a wired connection or a wireless connection. The information monitored by the sensor refers to the swing position of the second transmission member 23.
[0096] For example, when the sensor detects that the swing position of the second transmission member 23 is close to the set maximum value, the processor will control the motor 21 to stop or reverse rotation to stop further driving of the driving device 2 or make the driving device 2 move in the reverse direction, thereby preventing the projection of the casting gate 12 from exceeding the outermost edge of the iron mold 200.
[0097] In another exemplary embodiment, the swing position of the runner 1 can also be limited by a combination of a mechanical stopper and a sensor to ensure that the projection of the pouring port 12 on the iron mold 200 does not exceed the outermost edge of the iron mold 200. This embodiment does not impose any limitation on this.
[0098] See also Figure 1 and Figure 2 In some embodiments, the mobile casting mechanism 100 further includes a runner support 3, which is constructed to be disposed on the iron casting machine 300 and support the bottom of the runner 1, and the runner support 3 is rotatably connected to the bottom of the runner 1.
[0099] Specifically, the runner support 3 is provided to support the runner 1, thereby preventing the runner 1 from sagging and deforming due to weight. Furthermore, the rotatable connection between the runner 1 and the runner support 3 ensures smooth swinging motion and structural stability in high-temperature operating environments, thereby precisely controlling the motion trajectory of the pouring nozzle 12 and improving casting quality.
[0100] Among them, the runner support 3 can be fixed to the cast iron machine 300 by bolts or welding. The runner support 3 has a support shaft. A shaft sleeve is provided at the bottom of the runner 1. The shaft sleeve is sleeved on the support shaft and is loosely matched with the support shaft. The inner wall of the shaft sleeve and the outer surface of the support shaft form a rotating pair, so that the runner 1 can swing freely left and right around the support shaft.
[0101] See also Figures 1 to 4In some embodiments, the runner 1 includes a horizontal section 13 and a vertical section 14. The horizontal section 13 has a first trough 131. The vertical section 14 is located on the side of the horizontal section 13 facing the iron mold 200. The vertical section 14 has a second trough 141. One end of the second trough 141 adjacent to the horizontal section 13 is connected to the first trough 131, and the end of the second trough 141 facing away from the horizontal section 13 forms a casting port 12.
[0102] Specifically, the first trough body 131 in the horizontal section 13 is used to receive molten iron. The vertical section 14 is located on the side of the horizontal section 13 facing the iron mold 200. A second trough body 141 connected to the first trough body 131 is provided inside. A casting mouth 12 is formed at the end of the second trough body 141, so that the runner 1 forms an "L"-shaped structure, avoiding the problem of too long flow channel when the full horizontal arrangement is used, so that the molten iron can be quickly switched from horizontal transportation to vertical casting.
[0103] At the same time, the arrangement of the horizontal section 13 and the vertical section 14 makes the flow path of the molten iron from the horizontal section 13 to the vertical section 14 more direct, reducing flow resistance and facilitating the maintenance of the molten iron's temperature and fluidity. Furthermore, the arrangement of the vertical section 14 brings the pouring port 12 closer to the iron mold 200, improving casting accuracy and preventing temperature loss and oxidation of the molten iron during long-distance flow.
[0104] The specific structures of the first tank body 131 and the second tank body 141 can be adaptively designed according to actual needs.
[0105] For example, in this embodiment, the second trough body 141 adopts a trapezoidal structure that is wide at the top and narrow at the bottom, so that the molten iron can be gradually accelerated during the flow process to form a more concentrated casting stream.
[0106] See also Figure 3 In some embodiments, the diameter of the pouring port 12 gradually decreases along the flow direction of the molten iron (shown by a dotted line).
[0107] Specifically, in this embodiment, the entrance of the pouring nozzle 12 is designed as a relatively large opening. Along the direction of the molten iron flow, the inner wall gradually narrows inward at a gentle angle, ultimately forming a smaller outlet. This tapered structure allows the molten iron to be gradually compressed and accelerated during the flow process. When the molten iron flows into the wider entrance of the pouring nozzle 12, due to its large cross-sectional area, the molten iron maintains a relatively gentle flow state. As the channel gradually narrows, the molten iron is naturally compressed, and the flow rate increases accordingly, thereby forming a more concentrated and stable casting stream, which enables the molten iron to quickly fill various parts of the mold cavity.
[0108] At the same time, the tapered structure can also reduce the contact area between molten iron and air, reducing the probability of oxide inclusions.
[0109] In specific implementation, the diameter of the casting port 12 can be gradually reduced by adjusting the thickness of the refractory material on the surface of the iron mold 200 , or by directly adjusting the structure and size of the iron mold 200 .
[0110] The refractory material is a material capable of withstanding high temperatures and exhibiting excellent thermal shock resistance and corrosion resistance, thereby protecting the iron mold 200 from direct erosion by the high-temperature molten iron and regulating the flow characteristics of the molten iron to a certain extent. The specific composition of the refractory material can be determined based on the structure of the existing iron mold and will not be further described in this application.
[0111] Figure 6 for Figure 1 Schematic diagram of the structure of the mid-casting system without the iron mold 200.
[0112] See also Figure 1 、 Figure 2 and Figure 6 In some embodiments, the runner 1 has a runner 15, with both ends of the runner 15 connected to an outlet 410 and a return port 420 of an external device 400, respectively, forming a loop. The outlet 410 is used to output cooling medium into the runner 15. The casting system also includes a vibration device 500, which is disposed on a side of the runner 1 facing away from the casting trough 11.
[0113] Specifically, during the casting process, the temperature of the molten iron is usually high. When the molten iron passes through the runner 1 and enters the iron mold 200, the high-temperature molten iron will cause severe thermal shock to the iron mold 200, shortening the service life of the iron mold 200. At the same time, it may also cause the molten iron to flow unevenly in the mold, thereby causing shrinkage cavities, shrinkage porosity and other problems, seriously affecting the quality of the casting.
[0114] It should be noted that Figure 6 The vibration device 500 shown in the figure is a structural diagram to facilitate a better understanding of the casting system mentioned in the embodiment of the present application, and does not constitute a limitation on the size of the vibration device 500 relative to the runner 1.
[0115] See also Figure 1 、 Figure 2 and Figure 6 To solve the above problem, in this embodiment, a runner 1 is further provided in the runner 1. The two ends of the runner 15 are respectively connected to the outlet end 410 and the return end 420 of the external device 400 to form a loop, so that the cooling medium is output to the runner 15 through the outlet end 410 of the external device 400. After passing through the runner 15, the cooling medium circulates through the return end 420 of the external device 400 to cool the high-temperature molten iron in the runner 1, thereby ensuring a smooth casting process and ensuring the quality of the casting.
[0116] The external device 400 is a cooling medium supply device, such as a cooling water circulation system or refrigeration equipment. The cooling medium is primarily used to exchange heat with the high-temperature molten iron. The external device 400 and the cooling medium can be adaptively selected based on actual needs, and this embodiment does not impose any limitations on this. Exemplarily, the cooling medium is cooling oil.
[0117] However, during the cooling process of the molten iron, if the cooling rate is too fast or the cooling is uneven, it can easily cause the molten iron to solidify prematurely in the runner 1, interrupting the casting process or even damaging the runner 1, affecting the normal operation of the casting system. Therefore, the casting system provided in this embodiment also includes a vibration device 500. The vibration device 500 is arranged on the side of the runner 1 away from the casting trough 11. In this way, the vibration generated by the vibration device 500 can be used to keep the molten iron molecules in a state of motion during cooling, preventing the molten iron from solidifying in the runner 1 and ensuring that the molten iron can flow smoothly into the iron mold 200.
[0118] The vibration device 500 can be adaptively selected according to actual needs, and this embodiment does not impose any limitation on this.
[0119] Exemplarily, the vibration device 500 is an electromagnetic vibrator, which can control the frequency and amplitude of vibration by adjusting the current, thereby adapting to different casting requirements.
[0120] See also Figure 1 、 Figure 2 and Figure 6 In some embodiments, there are multiple runners 15 . Multiple runners 15 are sequentially arranged within the runner 1 along the width of the casting trough 11 , and the runners 15 extend within the runner 1 along the length of the casting trough 11 . This allows the cooling medium to be more evenly distributed throughout the runner 1 , achieving comprehensive cooling of the molten iron, ensuring uniform cooling of the molten iron, and improving cooling efficiency of the molten iron.
[0121] It should be noted that when the runner 1 is located at the center of the iron mold 200 in the width direction x, the groove width direction of the casting trough 11 is parallel to the width direction x of the iron mold 200, and the groove length direction of the casting trough 11 is perpendicular to the width direction x of the iron mold 200.
[0122] This embodiment does not limit the specific number and length of the flow channels 15, and an adaptive selection can be made according to actual needs.
[0123] See also Figure 1 and Figure 2In some embodiments, the casting system further includes a casting machine 300 and an iron mold 200. The iron mold 200 is movably mounted on a track of the casting machine 300 and is capable of reciprocating on the track. The side of the iron mold 200 facing the casting port 12 is provided with a heat-conducting material or a removable wear-resistant lining.
[0124] Specifically, the iron mold 200 can move back and forth on the track of the iron casting machine 300, so that the position can be flexibly adjusted according to different casting requirements.
[0125] Because the iron mold 200 is in direct contact with the hot molten iron, uneven thermal conductivity of the iron mold 200 can lead to local overheating, deformation, cracking, and shortened service life of the iron mold 200. Furthermore, local overheating of the iron mold 200 can affect the cooling rate and quality of the casting, leading to shrinkage cavities within the casting.
[0126] Therefore, the iron mold 200 provided in this embodiment is provided with a heat-conducting material on the surface facing the casting port 12 , thereby improving the thermal conductivity of the iron mold 200 , increasing the speed of heat transfer, and making the heat distribution more uniform.
[0127] The thermal conductive material can be selected according to actual needs, and this embodiment does not impose any restrictions on this. For example, the thermal conductive material can be a graphite material with good chemical stability to ensure that the thermal conductive material is not corroded by molten iron.
[0128] The iron mold 200 provided in this embodiment may further be provided with a wear-resistant lining on the side surface facing the casting port 12 to improve the impact resistance and wear resistance of the iron mold 200 and reduce the cost of replacing the entire iron mold 200.
[0129] The wear-resistant lining is detachably arranged on the iron mold 200, so that when the wear-resistant lining is worn or damaged, there is no need to replace the entire iron mold 200, only the wear-resistant lining needs to be replaced, thereby reducing the cost of replacing the entire iron mold 200.
[0130] In some embodiments, the wear-resistant lining plate is fixed to the iron mold 200 by bolt connection to ensure the stability of the connection between the wear-resistant lining plate and the iron mold 200.
[0131] In other embodiments, the connection method between the wear-resistant liner and the iron mold 200 may be adaptively selected according to actual needs, and this embodiment does not impose any limitation on this.
[0132] In this embodiment, the wear-resistant lining is made of a material with high hardness and high wear resistance, such as silicon carbide ceramics or cemented carbide, to ensure that the wear-resistant lining can effectively resist high temperature erosion and mechanical wear of molten iron, thereby extending the service life of the iron mold 200.
[0133] In other embodiments, the material of the wear-resistant lining plate may also be adaptively selected, and this embodiment does not impose any limitation on this.
[0134] In some embodiments, a heat-conducting material is provided on the surface of the wear-resistant lining to enhance the heat-conducting performance of the iron mold 200 .
