Description

Technical Field

[0001] This invention relates to the field of casting equipment technology, specifically to an integrated device for sequential solidification auxiliary heating and cooling of castings. Background Technology

[0002] Sequential solidification is a core principle in casting technology. Its basic meaning is: by controlling the temperature field of the casting through process means, the parts of the casting far from the riser solidify first, the parts close to the riser solidify next, and the riser itself solidifies last. When the molten metal shrinks in volume during solidification, the molten metal in the riser that has not yet solidified can continue to be replenished into the casting under the action of gravity or pressure, thereby effectively preventing defects such as shrinkage cavities and porosity inside the casting. In practical engineering applications, sequential solidification technology is widely used in the production of high-performance castings.

[0003] In existing technology, a riser is a cavity specifically created in the mold to store excess molten metal. During the sequential solidification of the casting, the molten metal inside the riser is kept in a liquid state to prolong its feeding time, and the cooling system accelerates the cooling and solidification of the casting body, artificially creating a strong temperature difference to achieve sequential solidification. However, in traditional casting, in order to ensure that the molten metal inside the riser solidifies last, heating wires are usually wrapped around the outside of the riser. However, the heat emitted by the heating wire is transferred unidirectionally from the outside to the inside. The temperature of the riser wall near the heating wire is extremely high, while the molten metal in the center of the riser is farthest from the heat source and has the lowest temperature. This temperature gradient distribution causes the molten metal in the center of the riser to solidify earlier than the molten metal near the riser wall, resulting in uneven heating.

[0004] Therefore, we propose an integrated device for sequential solidification auxiliary heating and cooling of castings to solve the problems mentioned above. Summary of the Invention

A mold body is fixedly connected to the bottom end of the injection pipe, and the mold body is placed above the sealing plate.

[0013] Preferably, the heating assembly further includes a forward and reverse motor and a rotating collar. The rotating collar is sleeved on the top of the riser outer tube. The outer surface of the rotating collar is evenly provided with multiple mounting slots along the circumferential direction. Each mounting slot has a mounting block inserted into its inner wall. Each mounting block has an arc-shaped plate fixedly connected to its bottom, and the arc-shaped plate is close to the outer surface of the riser outer tube.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 8 The present invention provides a technical solution: This invention provides an integrated device for sequential solidification auxiliary heating and cooling of castings, including a cooling component 2, a connecting component 3, a heating component 4, and a mold component 5. The mold component 5 includes an outer riser tube 503 and an inner riser tube 505. The outer riser tube 503 is arranged in a bucket shape, and the inner riser tube 505 is arranged in a V-shape. An inner heating cavity 506 is formed inside the inner riser tube 505. The heating component 4 includes multiple outer heating elements 412 and multiple inner heating elements 408. The multiple outer heating elements 412 are evenly arranged outside the outer riser tube 503. The inner heating elements 408 are evenly arranged on the inner wall of the inner heating cavity 506, and the multiple outer heating elements 412 and multiple inner heating elements 408 are evenly arranged along the circumferential direction. They are used for bidirectional heating of molten metal. Multiple reinforcing rods 504 are fixedly connected between the outer surface of the riser outer tube 503 and the inner wall of the riser inner tube 505. The space between the riser outer tube 503 and the riser inner tube 505 is used for injecting molten metal. The bottom of the riser outer tube 503 is fixedly connected to the injection pipe 502, and the bottom end of the injection pipe 502 is fixedly connected to the mold body 501.

[0023] In use, the outer riser tube 503 is a thin-walled, funnel-shaped structure, which facilitates the rapid transfer of external high temperature to the molten metal inside the riser wall. Multiple arc-shaped plates 411, after installation, are arranged to fit the funnel shape of the outer riser tube 503, and the arc-shaped plates 411 are close to the outer wall of the outer riser tube 503. An external heating element 412 is located on the concave surface of the arc-shaped plate 411. By energizing the external heating element 412, it heats the molten metal inside the outer riser tube 503 near its outer wall. The inner riser tube 505 is V-shaped. The inner riser tube 505 and the outer riser tube... The 503 sections are parallel to each other, facilitating the injection of molten metal. The inner heating plate 408, which is installed on the outer wall of the inner rotating block 407 inserted inside the inner heating cavity 506, is arc-shaped. The outer arc-shaped plate of the inner heating plate 408 is close to the inner wall of the inner heating cavity 506. By energizing the inner heating plate 408, the inner heating plate 408 heats the molten metal in the outer riser tube 503 near the inner riser tube 505. By heating the molten metal in the riser from both the inner and outer sides simultaneously, the problem of uneven temperature in the current riser heating method, which causes the molten metal in the center of the riser to solidify earlier than the molten metal near the riser wall, is solved.

[0024] It should also be noted that the cooling assembly 2 includes a water-cooled cavity 201. A set of limiting clamps 203 are fixedly connected to both outer surfaces of the water-cooled cavity 201. The two sets of limiting clamps 203 are symmetrically arranged, and the limiting clamps 203 are composed of an arc plate and a cylinder. A sealing plate 206 is installed on the top of the water-cooled cavity 201, and the mold body 501 is placed above the sealing plate 206.

[0025] Please see Figures 1 to 3Through the water cooling effect of the cooling component 2, the heat at the bottom of the mold body 501 can be quickly removed, thereby achieving sequential solidification of the casting. When the mold body 501 is placed above the sealing plate 206, the limiting clamps 203 on both sides will clamp the sides of the mold body 501, which can prevent the mold body 501 from moving during the injection of molten metal, so that the mold assembly 5 remains stable as a whole. Below the limiting clamp 203 is an arc plate, which can generate memory deformation under compression and unfolds when clamping the mold body 501. Above the limiting clamp 203 is a cylinder, which contacts the side of the mold body 501. The arc-shaped surface can avoid damage to the mold body 501.

[0026] It should also be noted that multiple guide plates 202 are fixedly connected to the bottom surface of the water-cooling cavity 201. The multiple guide plates 202 are installed alternately, and the structure of the guide plates 202 is wavy. They are used to slow down the water flow speed inside the water-cooling cavity 201. A sealing plate 206 is installed on the top of the water-cooling cavity 201. The bottom of the sealing plate 206 is tightly fitted with the top of the multiple guide plates 202. A water inlet 204 and a water outlet 205 are respectively opened on the outer surface of the water-cooling cavity 201 near both sides. The water inlet 204 is used to connect to the water source, and the water outlet 205 is used to connect to the drainage pipe. A fixed base plate 1 is fixedly installed on the bottom of the water-cooling cavity 201.

[0027] Please see Figures 1 to 3 When the mold body 501 is placed on the sealing plate 206, the water inlet 204 is connected to an external water source, and the external water source is turned on, allowing cold water to enter and exit the water cooling chamber 201 through the water inlet 204. After entering the water cooling chamber 201, the cold water will travel along the wavy guide plate 202 in a zigzag pattern. The wavy design slows down the flow speed of the cold water and lengthens the flow time of the cold water inside the water cooling chamber 201, allowing the cold water to fully absorb the heat emitted from the bottom of the mold body 501. This achieves the purpose of solidifying the molten metal at the bottom of the mold body 501 first, realizing sequential solidification from bottom to top. The heat at the bottom of the mold body 501 is transferred to the sealing plate 206, and the flowing cold water carries away the heat from the bottom of the sealing plate 206, thereby achieving bottom cooling.

[0028] It should also be noted that the connecting component 3 includes a cold zone connecting plate 301, which is fixedly installed on the outside of the water-cooled cavity 201. A heat insulation module 302 is bolted to the top of the cold zone connecting plate 301, and a hot zone connecting plate 303 is bolted to the top of the heat insulation module 302.

[0029] Please see Figure 1 and Figure 2The hot zone connecting plate 303 and the cold zone connecting plate 301 are installed together through the heat insulation module 302. Then, the hot zone connecting plate 303 is connected to the heating component 4, and the cold zone connecting plate 301 is connected to the cooling component 2, so that the heating component 4 and the cooling component 2 are integrated. The integrated heating and cooling design has the advantage of eliminating the need for mechanical movement of the heating and cooling equipment. By designing the heating and cooling as an integrated structure, the integrated and independent control of the heating and cooling functions can be achieved, and the heating and cooling can be controlled separately without the need for physical moving parts.

[0030] It should also be noted that the interior of the heat insulation module 302 is filled with a composite heat insulation structure. The heat insulation module 302 is used to effectively isolate the hot zone from the cold zone, and the hot zone connecting plate 303 is used to install the heating component 4.

[0031] Please see Figure 1 and Figure 2 The heat insulation module 302 set in the middle is an external reinforcing plate with a multi-layer composite heat insulation structure filled with aerogel, ceramic fiber and vacuum layer. This helps to effectively isolate the high-temperature riser area from the low-temperature casting area, so that although the heating zone and the cooling zone are physically a whole, the heating and cooling functions can be independently controlled.

[0032] It should also be noted that multiple reinforcing rods 504 are fixedly connected between the outer surface of the riser outer tube 503 and the inner wall of the riser inner tube 505. The space between the riser outer tube 503 and the riser inner tube 505 is used for injecting molten metal. An injection pipe 502 is fixedly connected to the bottom of the riser outer tube 503. A mold body 501 is fixedly connected to the bottom end of the injection pipe 502, and the mold body 501 is placed above the sealing plate 206.

[0033] Please see Figure 1 and Figure 2 The riser consists of two parts: an outer riser tube 503 and an inner riser tube 505, both of which are bucket-shaped. The outer wall of the inner riser tube 505 is parallel to the inner wall of the outer riser tube 503. The molten metal is poured in from the injection area between the outer riser tube 503 and the inner riser tube 505. Excess molten metal is stored in the middle area between the outer riser tube 503 and the inner riser tube 505. The outer riser tube 503 and the inner riser tube 505 are connected as a whole by multiple reinforcing rods 504. After the molten metal is injected into the riser, it flows into the injection pipe 502 and is injected into the mold body 501. When the casting inside the mold body 501 shrinks, the molten metal stored in the riser continues to flow downward to fill the gap between the casting and the mold body 501.

[0034] It should also be noted that the heating assembly 4 includes multiple external heating elements 412 and multiple internal heating elements 408. The multiple external heating elements 412 are evenly arranged on the outside of the riser outer tube 503, and the multiple internal heating elements 408 are evenly arranged on the inner wall of the inner heating cavity 506. The heating assembly 4 also includes a forward and reverse motor 401 and a rotating collar 403. The rotating collar 403 is sleeved on the top of the riser outer tube 503. Multiple mounting slots 409 are evenly opened on the outer surface of the rotating collar 403 along the circumferential direction. A mounting block 410 is inserted into the inner wall of each mounting slot 409. An arc-shaped plate 411 is fixedly connected to the bottom of each mounting block 410, and the arc-shaped plate 411 is close to the outer surface of the riser outer tube 503. Each external heating element 412 is respectively arranged on the inner wall of each arc-shaped plate 411.

[0035] Please see Figure 1 , Figure 2 , Figures 4 to 8 When the forward and reverse motor 401 drives the adjusting ring 404 to rotate, the arc-shaped plate 411 installed below the driving adjusting ring 404 will also rotate forward and reverse outside the riser outer tube 503, thereby driving the external heating element 412 to rotate synchronously and slowly. This effectively avoids local heating of the molten metal inside the riser, achieves uniform heating, suppresses uneven convection, and extends the life of the heating element. During installation, the adjusting ring 404 needs to be fitted onto the top of the riser outer tube 503 first, and then each mounting clip 410 is inserted into the corresponding mounting slot 409 so that the external heating element 412 is close to the riser outer tube 503, thereby completing the installation of the external heating component.

[0036] It should also be noted that the heating assembly 4 includes multiple external heating elements 412 and multiple internal heating elements 408. The multiple external heating elements 412 are evenly arranged outside the riser outer tube 503, and the multiple internal heating elements 408 are evenly arranged inside the inner wall of the inner heating cavity 506. Multiple reinforcing curved rods 406 are fixedly connected to the top of the rotating collar 403 along the circumferential direction. An inner rotating block 407 is fixedly connected between one end of the multiple reinforcing curved rods 406. The inner rotating block 407 is inserted inside the inner heating cavity 506, and the multiple internal heating elements 408 are evenly arranged outside the inner rotating block 407 along the circumferential direction.

[0037] Please see Figure 1 , Figure 2 , Figures 4 to 6By using multiple reinforcing cranks 406 as connectors, the inner rotating block 407 and the adjusting ring 404 set at the center are connected as a whole. When the adjusting ring 404 is sleeved on the top of the riser outer tube 503, the inner rotating block 407 is simultaneously inserted into the inner heating chamber 506. When the adjusting ring 404 rotates, the inner heating plate 408 set on the outside of the inner rotating block 407 also rotates in both directions at the same time, so that the molten metal near the riser inner tube 505 can be heated evenly. By adjusting the rotation speed, the average heating time of each position can be indirectly changed, so that the heating time of a single position can be selected and adjusted for molten metal of different materials.

[0038] It should also be noted that the output shaft of the forward and reverse motor 401 is fixedly connected to a drive gear 402, and an adjusting ring 404 is fixedly connected to the outer surface of the rotating collar 403 near its top. An adjusting tooth 405 is fixedly connected to the outer surface of the adjusting ring 404, and the outer surface of the drive gear 402 meshes with the outer surface of the adjusting tooth 405.

[0039] Please see Figures 1 to 6 By starting the forward and reverse motor 401 and setting its rotation angle to match the length of the adjusting tooth 405, the output shaft of the forward and reverse motor 401 rotates, which drives the drive gear 402 to rotate. Under the meshing connection between the drive gear 402 and the adjusting tooth 405, the adjusting ring 404 is driven to rotate. When the meshing point of the adjusting tooth 405 and the drive gear 402 reaches the edge of the adjusting tooth 405, it is made to rotate in the opposite direction. Next, when the meshing point of the adjusting tooth 405 and the drive gear 402 reaches the other edge of the adjusting tooth 405, it is made to change the rotation direction again. The forward and reverse motor 401 records the rotation angle and then maintains the angle for forward and reverse rotation. In this embodiment, the preferred model of the forward and reverse motor 401 is 60KTYZ.

[0040] The working principle of this device is as follows: During use, the water cooling effect of the cooling component 2 can quickly remove the heat from the bottom of the mold body 501. When the mold body 501 is placed above the sealing plate 206, the limiting clamps 203 on both sides will clamp the sides of the mold body 501. After placing the mold body 501 on the sealing plate 206, the water inlet 204 is connected to an external water source. The external water source is turned on, allowing cold water to enter and exit the water cooling chamber 201 through the water inlet 204. After entering the water cooling chamber 201, the cold water will travel along the wavy guide plate 202, allowing the cold water to fully absorb the heat emitted from the bottom of the mold body 501, achieving the purpose of the bottom molten metal of the mold body 501 solidifying first. The heat is then transferred through the heat insulation module 302. Hot zone connecting plate 303 and cold zone connecting plate 301 are installed together. Then, hot zone connecting plate 303 is connected to heating component 4, and cold zone connecting plate 301 is connected to cooling component 2, so that heating component 4 and cooling component 2 are integrated. Multiple arc-shaped plates 411 are arranged in a funnel shape to fit the riser outer tube 503 after installation, and the arc-shaped plates 411 can be close to the outer wall of the riser outer tube 503. The outer heating element 412 is set on the concave surface of the arc-shaped plate 411. By energizing the outer heating element 412, the outer heating element 412 heats the molten metal inside the riser outer tube 503 near its outer wall. The outer arc-shaped piece of the inner heating element 408 is close to the inner wall of the inner heating cavity 506. 8. When energized, the internal heating element 408 heats the molten metal inside the riser outer tube 503 near the riser inner tube 505. Heating is achieved through simultaneous internal and external heating. The forward / reverse motor 401 is activated, its rotation angle set to match the length of the adjusting tooth 405. The output shaft of the forward / reverse motor 401 rotates, driving the drive gear 402. With the drive gear 402 meshing with the adjusting tooth 405, the adjusting ring 404 rotates. When the meshing point of the adjusting tooth 405 with the drive gear 402 reaches the edge of the adjusting tooth 405, it rotates in the opposite direction. The next step is to rotate the adjusting tooth 405 in the opposite direction when the meshing point reaches the other edge of the adjusting tooth 405. When the rotation direction is changed again, the forward and reverse motor 401 records the rotation angle and then maintains that angle for forward and reverse rotation. When the forward and reverse motor 401 drives the adjusting ring 404 to rotate, the arc-shaped plate 411 installed below the driving adjusting ring 404 will also rotate forward and reverse outside the riser outer tube 503, thereby driving the external heating element 412 to rotate synchronously and slowly. During installation, the adjusting ring 404 needs to be fitted onto the top of the riser outer tube 503 first, and then each mounting clip 410 is inserted into the corresponding mounting slot 409, so that the external heating element 412 is close to the riser outer tube 503, thus completing the installation of the external heating component. Multiple reinforcing curved rods 406 are used as connections.The inner rotating block 407 and the adjusting ring 404, located at the center, are connected as a whole. When the adjusting ring 404 is fitted onto the top of the riser outer tube 503, the inner rotating block 407 is simultaneously inserted into the inner heating chamber 506. When the adjusting ring 404 rotates, the inner heating element 408 located outside the inner rotating block 407 also rotates in both directions, thus ensuring that the molten metal near the riser inner tube 505 is heated evenly.

[0041] The wiring diagram of the forward and reverse motor 401 in this invention is common knowledge in the field, and its working principle is a well-known technology. The appropriate model is selected according to the actual use. Therefore, the control method and wiring layout of the forward and reverse motor 401 will not be explained in detail.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
