[0045] In a first aspect, the present invention provides a hot die casting device for preparing ceramic products such as ceramic atomization cores.

[0046] Reference Figure 1-5 The hot die casting equipment 100 includes an operating table 1, a material storage component 2, and a grouting component 3. Figure 1 and Figure 2 As shown, the operating table 1 includes a table top for placing a mold to be grouted (not shown in the figure), and a grouting port 11 is provided on the table top that passes through the table top. Figure 1 and Figure 3As shown, the storage assembly 2 includes a first heating and stirring barrel 21, a second heating and stirring barrel 22, and a discharge pipe 23 connected between the first heating and stirring barrel 21 and the second heating and stirring barrel 22, which are arranged on the operating table 1. The first heating and stirring barrel 21 is used to heat, stir, and store the slurry. The first heating and stirring barrel 21 is connected to the second heating and stirring barrel 22 through the discharge pipe 23 and can transport the heated and stirred slurry to the second heating and stirring barrel 22. The second heating and stirring barrel 22 is used to heat and stir the slurry. The second heating and stirring barrel 22 is connected to the grouting port 11 and can transport the heated and stirred slurry to the grouting port 11 to inject the slurry into the mold to be grouted. Figure 1 As shown, the grouting assembly 3 includes a mold pressing device 31 and a discharge device 32 arranged on the operating table 1. The mold pressing device 31 is used to press the mold to be grouting placed on the table, and the discharge device 32 is connected to the storage assembly 2, and is used to transport the slurry in the second heating and stirring barrel 22 to the grouting port 11.

[0047] The above-mentioned hot die casting equipment 100 includes an operating table 1, a material storage component 2 and a grouting component 3, wherein the operating table 1 can place the mold to be grouted, the material storage component 2 can process the ceramic raw material into a liquid flowable slurry and store it, and the grouting component 3 can inject the slurry stored in the material storage component 2 into the mold to be grouted. Therefore, the above-mentioned hot die casting equipment 100 can be used to prepare a ceramic atomization core. Furthermore, since the storage assembly 2 includes a first heating and stirring barrel 21, a second heating and stirring barrel 22 and a discharge pipe 23 connected between the first heating and stirring barrel 21 and the second heating and stirring barrel 22, the first heating and stirring barrel 21 is used to heat, stir and store the slurry and can transport the heated and stirred slurry to the second heating and stirring barrel 22, and the second heating and stirring barrel 22 is used to heat and stir the slurry and can transport the heated and stirred slurry to the grouting port 11. In this way, when using the above-mentioned hot die-casting equipment 100 to prepare a ceramic atomization core, ceramic raw materials can be first added to the first heating and stirring barrel 21 and heated and stirred. After the slurry processing is completed, it is transported to the second heating and stirring barrel 22 to continue heating and stirring and gradually injected into the mold to be grouted. While grouting, ceramic raw materials are continuously added to the first heating and stirring barrel 21 and heated and stirred to prepare supplementary slurry, and when the slurry in the second heating and stirring barrel 22 is insufficient, the supplementary slurry is transported to the second heating and stirring barrel 22, that is, the first heating and stirring barrel 21 can be used as both a slurry processing device and a slurry storage device. In summary, the hot die casting equipment 100 provided by the present invention improves the structure of the material storage component 2 and simultaneously sets the first heating and stirring barrel 21 and the second heating and stirring barrel 22, so that the equipment can simultaneously prepare the slurry while injecting the slurry, and the first heating and stirring barrel 21 and the second heating and stirring barrel 22 are directly connected to directly complete the slurry transportation. In this way, in the process of preparing the ceramic atomization core, there is no need to stop the machine or disassemble the machine to replenish the slurry, and continuous production can be achieved, thereby effectively improving production efficiency. In addition, by setting the first heating and stirring barrel 21 and the second heating and stirring barrel 22 at the same time, the slurry storage capacity of the hot die casting equipment 100 can be increased, the number of slurry injections can be reduced, and the problems of slurry volatilization and changes in the physicochemical properties of the slurry caused by long-term stirring of a large-volume heating and stirring barrel can be avoided, and the reliability is high.

[0048] It should be noted that the hot die casting equipment 100 provided by the present invention also includes a controller (not shown in the figure), which is electrically connected to the material storage component 2 and the grouting component 3 to achieve automatic control of the material storage component 2 and the grouting component 3.

[0049] In one embodiment, in order to facilitate the fixing of the mold to be grouted, Figure 1 and Figure 2 As shown, a positioning platform 12 for placing the mold is provided on the table top of the operating table 1 , and the grouting port 11 passes through the positioning platform 12 .

[0050] Furthermore, a positioning groove for limiting the position of the mold may be provided on the positioning platform 12, and the grouting port 11 may be provided at the bottom of the positioning groove.

[0051] It can be understood that in some embodiments, a plurality of limit blocks for abutting the mold may be provided on the table top of the operating table 1 , and the plurality of limit blocks are provided around the grouting port 11 .

[0052] The melting point of ceramic raw materials is relatively high. Under normal temperature conditions, the liquid slurry will quickly cool and solidify. In one embodiment, in order to prevent the slurry from solidifying and blocking the discharge pipe 23, the discharge pipe 23 is made of a heat-insulating material. Alternatively, in one embodiment, a heating sleeve may be provided on the discharge pipe 23.

[0053] In one embodiment, to ensure that the first heating and stirring barrel 21 can store enough slurry, the volume of the first heating and stirring barrel 21 is greater than the volume of the second heating and stirring barrel 22. Optionally, the volume of the first heating and stirring barrel 21 is 1.5 times the volume of the second stirring barrel. In addition, in order to avoid the volatilization of the slurry and the change of the physicochemical properties of the slurry caused by long-term stirring, the volume of the first heating and stirring barrel 21 and the second heating and stirring barrel 22 should not be too large.

[0054] It should be noted that when conveying the slurry, part of the slurry will remain in the first heating and stirring barrel 21. In the subsequent feeding process, different batches of ceramic raw materials can be evenly mixed through continuous heating and stirring, thereby ensuring the stability of the slurry and ceramic product performance.

[0055] In one embodiment, if Figure 1 and Figure 3 As shown, the first heating and stirring barrel 21 is arranged above the table, and the second heating and stirring barrel 22 is arranged below the table; both the first heating and stirring barrel 21 and the second heating and stirring barrel 22 are provided with a stirring device 24 and a heating device (not shown in the figure), and the first heating and stirring barrel 21 is also provided with a feeding port 211; the first heating and stirring barrel 21 is provided with a slurry outlet, and the second heating and stirring barrel 22 is provided with a slurry inlet, and one end of the discharge pipe 23 is connected to the slurry outlet, and the other end is connected to the slurry inlet. With the above design, the setting height of the first heating and stirring barrel 21 is higher than the setting height of the second heating and stirring barrel 22, and the slurry in the first heating and stirring barrel 21 can flow into the second heating and stirring barrel 22 under the action of gravity, without the need to be equipped with a power device for conveying the slurry, with a simple structure, easy use, and low cost.

[0056] It can be understood that in some embodiments, the first heating and stirring barrel 21 and the second heating and stirring barrel 22 can be both arranged under the table, and the first heating and stirring barrel 21 or the discharge pipe 23 is connected to a power device for conveying the slurry, which can be specifically designed according to actual conditions and is not limited here.

[0057] In one embodiment, the barrel bodies of the first heating and stirring barrel 21 and the second heating and stirring barrel 22 are both composed of an inner and outer double-layer structure, wherein the inner layer structure is made of stainless steel material, and the outer layer structure is made of thermal insulation material, and the space between the inner and outer double-layer structures is filled with heat transfer fluid. The heating device includes a plurality of heating wires arranged between the inner and outer double-side structures. The stirring device 24 includes a stirring motor, a stirring rod extending into the barrel, and a stirring fan blade. Among them, Figure 3 and Figure 5 As shown, the stirring device 24 of the first heating and stirring barrel 21 extends into the barrel from the top, and the stirring device 24 of the second heating and stirring barrel 22 extends into the barrel from the bottom.

[0058] Furthermore, the first heating and stirring barrel 21 and the second heating and stirring barrel 22 are also provided with a temperature sensor and a slurry shortage sensor.

[0059] Furthermore, in order to facilitate the connection between the first heating and stirring barrel 21 and the second heating and stirring barrel 22, as shown in FIG. Figure 1 and Figure 3 As shown, a conveying hole (not shown in the figure) is also provided on the table top, one end of the discharge pipe 23 is connected to the slurry outlet of the first heating and stirring barrel 21, and the other end is inserted into the conveying hole and connected to the slurry inlet of the second heating and stirring barrel 22. The above design facilitates the arrangement of the discharge pipe 23. When the first heating and stirring barrel 21 and the second heating and stirring barrel 22 are at different positions, the first heating and stirring barrel 21 and the second heating and stirring barrel 22 can be connected by using a shorter discharge pipe 23, so as to facilitate the conveying of slurry. In addition, the shorter length of the discharge pipe 23 can also reduce the risk of cooling and solidification of the slurry in the discharge pipe 23.

[0060] It should be noted that the specific position of the conveying hole can be designed according to the installation position of the first heating and stirring barrel 21 and the second heating and stirring barrel 22, and the opening positions of the slurry outlet and the slurry inlet, and is not limited here.

[0061] Furthermore, to ensure that the slurry in the first heating and stirring barrel 21 can flow smoothly into the second heating and stirring barrel 22, the slurry outlet of the first heating and stirring barrel 21 is set at the bottom of the barrel body, and the slurry inlet of the second heating and stirring barrel 22 is set at the top of the barrel body. In addition, the slurry outlet of the first heating and stirring barrel 21 is set at the bottom of the barrel body, which can also avoid the problem of slurry deposition at the bottom and uneven stirring.

[0062] In one embodiment, a slurry discharge valve is provided at the slurry discharge port of the first heating and stirring barrel 21, and a slurry inlet valve is provided at the slurry inlet of the second heating and stirring barrel 22. When in use, the slurry discharge valve at the slurry discharge port of the first heating and stirring barrel 21 and the slurry inlet valve at the slurry inlet of the second heating and stirring barrel 22 can be opened first, so that the slurry in the first heating and stirring barrel 21 flows into the second heating and stirring barrel 22 through the discharge pipe 23. When the feed amount of the second heating and stirring barrel 22 reaches the preset requirement, the slurry discharge valve is closed, and when the slurry in the discharge pipe 23 flows out, the slurry inlet valve is closed. The above design is adopted to facilitate the control of the discharge amount of the first heating and stirring barrel 21 and the feed amount of the second heating and stirring barrel 22, and by adjusting the opening and closing sequence of the slurry discharge valve and the slurry inlet valve, the slurry accumulation in the discharge pipe 23 can be reduced, thereby further reducing the risk of the slurry in the discharge pipe 23 solidifying and blocking the pipeline, and the reliability is high.

[0063] It should be noted that, in order to ensure the stirring effect of the stirring device 24, when injecting ceramic raw materials into the first heating stirring barrel 21 or conveying slurry into the second heating stirring barrel 22, it is sufficient to reach 2 / 3 of its volume.

[0064] In one embodiment, to further improve production efficiency, Figure 1 and Figure 4 As shown, the operating table 1 is provided with a mold loading area 13, a grouting area 14 and a demoulding area 16 in sequence. The mold loading area 13 is used to provide or assemble the mold to be grouted, the grouting area 14 is opposite to the grouting port 11 and is used to grout the mold to be grouted, and the demoulding area 16 is used to take out the green body and disassemble the mold. Figure 1 and Figure 2 As shown, the hot die casting equipment 100 also includes a conveying assembly 4 disposed on the operating table 1, and the conveying assembly 4 is used to transfer the mold between the mold loading area 13, the grouting area 14 and the demolding area 16, forming the mold loading, grouting, demolding and mold loading closing process. With the above design, the mold loading, grouting and demolding processes can be respectively performed at different stations, so that the mold loading, grouting and demolding of the same mold can be completed at different stations, and while the first group of molds are being demolded, the second group of molds can also be grouted and the third group of molds can be loaded, thereby achieving uninterrupted production and further improving production efficiency.

[0065] Among them, the mold loading area 13, the grouting area 14 and the demoulding area 16 can be provided with multiple workstations, which can be specifically designed according to actual conditions and are not limited here.

[0066] It should be noted that the mold filling, grouting and demoulding operations can be completed by other automated equipment, such as a robot arm, or manually, and are not limited here. In addition, when filling the mold, components such as resistance wires can also be installed in the mold to be grouted, and can be integrally formed with the slurry in the mold during subsequent grouting and die casting.

[0067] When relying on manual mold loading, grouting and demolding, the mold loading, grouting and demolding can be assigned to different workstations, and multiple operators are responsible for the mold loading, grouting and demolding processes at different workstations. This can achieve uninterrupted production of a hot die-casting equipment 100 and can reduce the waiting time of the grouting component 3 during the two grouting processes, thereby effectively improving production efficiency.

[0068] Further, in order to facilitate the removal of the mold, as Figure 1 and Figure 4 As shown, the mold loading area 13, the grouting area 14 and the demoulding area 16 are arranged on the edge of the table around the grouting port 11. The conveying assembly 4 includes a conveyor belt 41 and a motor 42 arranged on the table around the grouting port 11, and the conveyor belt 41 can rotate along the distribution direction of the mold loading area 13, the grouting area 14 and the demoulding area 16. Among them, the conveying rate of the conveyor belt 41 can be designed according to the grouting rate, which is not limited here. The conveyor belt 41 has a simple structure and is convenient for taking and placing the mold. The conveyor belt 41 is arranged on the table of the operating table 1, and runs efficiently and stably, and can stably transport the mold.

[0069] It should be noted that after demoulding is completed in the demoulding area 16, the disassembled mold can be put back on the conveyor belt 41 and transported to the mold loading area 13 to enter the next cycle.

[0070] In order to ensure the quality of ceramic products, in the actual production process, it is necessary to perform demoulding after the green body is completely cooled and solidified. In one embodiment, in order to improve the cooling effect and shorten the cooling process, Figure 1 and Figure 4 As shown, a cooling zone 15 is provided between the grouting zone 14 and the demoulding zone 16, and the cooling zone 15 is provided with a cooling channel 17 and a cooling fan (not shown in the figure). The cooling channel 17 is arranged above the conveyor belt 41, and the cooling fan is arranged in the cooling channel 17. The cooling channel 17 can enclose a cooling area, and the cooling fan can accelerate the air flow in the cooling area and enhance the heat exchange. When the conveyor belt 41 transports the mold through the cooling zone 15, the green body is cooled faster.

[0071] In one embodiment, if Figure 1 and Figure 3As shown, the discharge device 32 includes an air compressor 321 and a slurry discharge pipe (not shown in the figure) arranged on the operating table 1. One end of the slurry discharge pipe is connected to the grouting port 11, and the other end is connected to the second heating and stirring barrel 22 and extends into the slurry. The air compressor 321 is connected to the top of the second heating and stirring barrel 22. When the air compressor 321 is started, compressed air can be filled into the second heating and stirring barrel 22, thereby increasing the pressure in the second heating and stirring barrel 22. Under the action of high pressure, the slurry can flow upward from the slurry discharge pipe to the grouting port 11 and be injected into the mold to be grouted. Grouting can be achieved by using compressed air to increase pressure, which can avoid slurry pollution, is more environmentally friendly, and is easy to clean. In addition, the air compressor 321 is sensitive to reaction, which is convenient for regulating the grouting process.

[0072] Furthermore, in order to ensure that the subsequent grouting process can proceed smoothly, after each grouting is completed, the second heating and stirring barrel 22 needs to be depressurized. In one embodiment, an exhaust valve is provided on the top of the second heating and stirring barrel 22. After the grouting is completed, the exhaust valve is opened to restore the pressure in the second heating and stirring barrel 22 to normal, and the slurry in the slurry outlet pipe flows back into the barrel. It can be understood that the top of the second heating and stirring barrel 22 is not limited to the top surface of the barrel body, but also includes the upper part of the side wall. The actual setting position of the exhaust valve depends on the structure and installation position of the second heating barrel.

[0073] It can be understood that in some embodiments, the drainage device can also be a drainage pump arranged on the slurry discharge pipe.

[0074] In one embodiment, if Figure 1 and Figure 3 As shown, the die pressing device 31 includes a mounting frame 311 and a pneumatic telescopic rod 312. The mounting frame 311 is fixedly arranged on the table and used to fix the pneumatic telescopic rod 312. The pneumatic telescopic rod 312 includes a fixed portion 3121 and a movable portion 3122. The fixed portion 3121 is arranged on the mounting frame 311. The movable portion 3122 can move relative to the fixed portion 3121 toward or away from the table. When the movable portion 3122 moves toward the table, it can abut against the mold to be grouted and can press the mold to be grouted. The pneumatic telescopic rod 312 has a large telescopic range and can be used to fix molds of different sizes. It has a good pressing effect and is convenient for taking and placing the mold. In addition, the pneumatic telescopic rod 312 has a simple structure, is easy to maintain, and has a long service life.

[0075] Furthermore, in order to increase the adjustment range of the die pressing device 31, when the pneumatic telescopic rod 312 is installed on the mounting frame 311, the mounting height is adjustable, which can be specifically designed according to actual conditions and is not limited here.

[0076] Furthermore, in order to reduce the wear generated during the pressing process and increase the service life of the mold and the pneumatic telescopic rod 312 , a rubber pad may be provided at the free end of the movable portion 3122 of the pneumatic telescopic rod 312 .

[0077] In one embodiment, the pneumatic telescopic rod 312 is connected to the air compressor 321 through an air inlet pipe. When the air compressor 321 is started, compressed air can be charged into the fixed part 3121 of the pneumatic telescopic rod 312, thereby increasing the pressure in the fixed part 3121. Under the action of high pressure, the movable part 3122 moves toward the side close to the table and presses onto the mold surface.

Alternatively, in one embodiment, the hot die casting equipment 100 includes at least two sets of air compressors 321, and the second heating and stirring barrel 22 and the pneumatic telescopic rod 312 are respectively connected to different air compressors 321.

[0079] Furthermore, after the grouting is completed, it is necessary to adjust the pneumatic telescopic rod 312 so that the movable part 3122 is away from the mold, so as to facilitate the removal and placement of the mold. In one embodiment, the pneumatic telescopic rod 312 is also connected to an exhaust valve. After the grouting is completed, the exhaust valve is opened to reduce the pressure in the fixed part 3121 of the pneumatic telescopic rod 312, and the movable part 3122 can be retracted into the fixed part 3121, and the pneumatic telescopic rod 312 is restored. The specific use process of the pneumatic telescopic rod 312 is as follows: when it is necessary to grout the mold, start the air compressor 321 and open the air intake valve connected to the pneumatic telescopic rod 312, and use compressed air to increase the pressure so that the pneumatic telescopic rod 312 is extended and pressed to the surface of the mold; after the mold is pressed and fixed on the table top of the operating table 1, the air intake valve is closed; after the grouting is completed, the exhaust valve is opened to restore the pneumatic telescopic rod 312 and release the mold.

[0080] It can be understood that in some embodiments, the die pressing device 31 may include a fixed frame disposed on the table and an adjusting screw disposed on the fixed frame, and the adjusting screw may be rotated to adjust the distance between the fixed frame and the table surface of the operating table 1, and when the adjusting screw moves toward the table surface close to the operating table 1, it may abut against the mold surface and press the mold. Alternatively, in some embodiments, the die pressing device 31 may also include a hydraulic telescopic rod.

Furthermore, by arranging the mold loading area 13, the grouting area 14, the demolding area 16 and the conveying component 4 for conveying the mold on the operating table 1, it is possible to realize the mold loading, grouting and demolding processes at different stations, and to carry out the mold loading, grouting and demolding processes on multiple groups of molds at the same time, so that uninterrupted production can be achieved, thereby further improving the production efficiency.

[0082] In a second aspect, the present invention further provides a method for preparing a ceramic atomizer core, wherein the method utilizes the hot die casting device 100 in the first aspect to prepare the ceramic atomizer core.

[0086] The first heating and stirring barrel 21 is provided with a heating device and a stirring device 24 . The heating device can melt the block-shaped ceramic raw material into a flowable liquid slurry, and the stirring device 24 can fully mix and homogenize the liquid slurry.

[0088] The second heating and stirring barrel 22 is provided with a heating device and a stirring device 24. The heating device can continue to heat the slurry to maintain the slurry at a preset temperature to prevent the slurry from cooling and solidifying. The stirring device 24 can continue to stir the slurry to avoid slurry sedimentation and insufficient homogenization.

[0089] The parameters of the second heating and stirring barrel 22, such as the heating temperature and stirring rate, can be set according to the properties of the slurry and production requirements.

[0090] After the slurry in the first heating and stirring barrel 21 is transported to the second heating and stirring barrel 22, the slurry to be homogenized is continued to be added to the first heating and stirring barrel 21 and heated and stirred to prepare supplementary slurry, thereby enabling the slurry to be prepared simultaneously with grouting to achieve continuous production.

[0091] S300, placing the mold to be grouted on the table, aligning the mold to be grouted with the grouting port 11, and pressing the mold device 31 to press the mold to be grouted.

[0092] The mold pressing device 31 can press and fix the mold onto the table surface of the operating table 1, and can prevent the mold from moving back and forth during the grouting process, thereby ensuring the grouting effect.

[0093] S400, opening the discharge device 32, and injecting the slurry in the second heating and stirring barrel 22 into the mold to be slurry injected.

[0094] The hot die casting equipment 100 also includes a slurry injection assembly 3, which can be used to transport the slurry in the second heating and stirring barrel 22 to the mold to be slurried.

[0095] The preparation method provided by the present invention utilizes a hot die casting device 100 to process the slurry and perform slurry injection, and can prepare products such as ceramic atomizer cores. The hot die casting device 100 includes a first heating and stirring barrel 21 and a second heating and stirring barrel 22. After the slurry in the first heating and stirring barrel 21 is transported to the second heating and stirring barrel 22, the slurry to be homogenized is continued to be added to the first heating and stirring barrel 21 and the heating and stirring treatment is continued. The slurry can be prepared synchronously while slurry injection is performed and the slurry transportation can be completed directly. When the ceramic atomizer core is prepared by the preparation method, there is no need to stop the machine or disassemble the machine to replenish the slurry, and continuous production can be achieved, thereby effectively improving production efficiency.

[0096] Furthermore, if Figure 1 and Figure 7 As shown, step S100 includes:

[0097] S11 , putting the slurry to be homogenized into the first heating and stirring barrel 21 .

[0098] To ensure the stirring effect of the first heating and stirring barrel 21 and the homogenization effect of the slurry, optionally, the amount of slurry added to the barrel does not exceed 2 / 3 of the barrel volume.

[0099] S12, turning on the heating device of the first heating and stirring barrel 21 to heat the slurry to be homogenized until it is completely melted.

[0100] Turning on the heating device before stirring can melt the blocky ceramic raw materials into a flowable liquid slurry, thereby facilitating subsequent stirring processing.

[0101] The heating temperature of the heating device can be set according to the physical and chemical properties of the slurry, and is not limited here.

[0102] S13, turning on the stirring device 24 of the first heating and stirring barrel 21 to heat and stir the slurry to be homogenized.

[0103] The minimum stirring time, stirring speed and other parameters of the stirring device 24 can be set according to the physical and chemical properties of the slurry and production requirements. Optionally, in one embodiment, the stirring device 24 includes a stirring motor, a stirring rod extending into the barrel and a stirring fan blade, and the stirring speed of the stirring device 24 is 80-240 rpm.

[0104] Furthermore, if Figure 1 , Figure 3 and Figure 8 As shown, the first heating and stirring barrel 21 is provided with a feeding port 211 and a slurry discharge valve, and the second heating and stirring barrel 22 is provided with a slurry inlet valve. Step S200 includes:

[0105] S21, opening the slurry outlet valve of the first heating and stirring barrel 21 and the slurry inlet valve of the second heating and stirring barrel 22, so that the slurry in the first heating and stirring barrel 21 is transported to the second heating and stirring barrel 22, and the second heating and stirring barrel 22 heats and stirs the slurry.

[0106] The second heating and stirring barrel 22 is provided with a slurry shortage sensor. When the slurry in the second heating and stirring barrel 22 is insufficient, the slurry outlet valve and the slurry inlet valve can be controlled to open to replenish the slurry.

[0107] S22, after injecting a preset volume of slurry, close the slurry outlet valve and the slurry inlet valve, and add the slurry to be homogenized into the first heating and stirring barrel 21 from the feeding port 211.

[0108] To ensure the stirring effect of the second heating and stirring barrel 22 and the homogenization effect of the slurry, optionally, the amount of slurry delivered to the barrel does not exceed 2 / 3 of the barrel volume.

[0109] Optionally, after closing the slurry discharge valve, wait for a period of time, and close the feed valve when the slurry in the discharge pipe 23 has flowed out. Closing the slurry discharge valve first and then closing the slurry feed valve can prevent the slurry from accumulating in the discharge pipe 23, thereby reducing the risk of the slurry in the discharge pipe 23 solidifying and blocking the pipeline.

[0110] In order to prevent the slurry from solidifying, in one embodiment, before the slurry in the first heating and stirring barrel 21 is transported to the second heating and stirring barrel 22 for continued stirring, the preparation method further includes:

[0111] The heating device of the second heating and stirring barrel 22 is turned on to raise the temperature in the second heating and stirring barrel 22 to the melting temperature of the slurry.

[0112] Preheating the second heating and stirring barrel 22 in advance can prevent the slurry from cooling and solidifying during the process of being conveyed to the second heating and stirring barrel 22, thereby reducing the risk of clogging of the slurry inlet and further improving production efficiency.

[0113] It can be understood that in order to avoid slurry sedimentation and ensure uniform mixing of the slurry, the stirring device 24 can be turned on before the first heating and stirring barrel 21 conveys the slurry to the second heating and stirring barrel 22 .

[0114] In summary, the preparation method of the ceramic atomization core provided by the present invention can effectively reduce the risk of clogging of the hot die casting equipment 100 and improve production efficiency by optimizing the grouting and feeding process.
