Description

Technical Field

[0001] The invention relates to the technical field of casting equipment, in particular to an investment silica sol quantitative pouring casting equipment and a casting process. Background Art

[0002] In modern industry, casting is used instead of forging, and the process is moving towards small or no cutting, high precision, high surface finish, and complex parts or assemblies that are difficult to process by other methods. This has opened up broad application prospects for precision casting technology. Silica sol is increasingly used in modern investment casting due to its relatively simple manufacturing process, low cost, convenient source, and pollution-free. Compared with other investment casting processes, the higher strength of silica sol mold shell makes it possible to produce larger-sized precision castings by investment casting.

[0003] However, when pouring, the forging equipment uses gravity to discharge the silica sol by tilting the storage component, and cannot effectively control the flow of the silica sol. This can easily lead to casting defects caused by excessive or insufficient pouring, resulting in excessive use of materials and increased product scrap rate. In addition, non-quantitative pouring requires frequent manual adjustment of the pouring amount, which increases the complexity and labor intensity of the operation. Non-quantitative pouring may cause temperature fluctuations and affect the quality of the casting.

[0004] When the forging equipment is poured, since the silica sol is poured into the mold, the silica sol poured first will cool down first, and the silica sol poured later will have a temperature difference with the silica sol poured first, which will make deformation or dimensional accuracy problems more likely to occur, and increase the difficulty and time of subsequent processing. Summary of the Invention

[0005] The purpose of the present invention is to provide an investment silica sol quantitative pouring casting device and a casting process to solve the problems raised in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] The forging equipment includes a desktop component, a storage component and a temperature control component. A discharge component is provided at the bottom of the storage component, and a mold component is provided at the output end of the discharge component. The mold component is located above the desktop component. The discharge component is used to control the flow rate of the silica sol. A temperature control component is provided on the mold assembly, and the temperature control component is used to quickly cool the mold.

[0008] Its desktop component is used to transport and place the mold component. The mold component is used to shape the silica sol, and then the silica sol in the mold is cooled by the temperature control component on the mold component. The temperature control component is used to quickly shape the silica sol, and can also eliminate bubbles in the silica sol, thereby improving the molding accuracy of the casting and the service life (effect) of the mold. The storage component is used to store high-temperature silica sol and pour it at the input end of the module component through the discharging component. The silica sol will produce bubbles during the transportation process, which will cause pores on the surface or inside of the casting when the silica sol is molded. These pores will affect the appearance quality of the casting. The storage component not only maintains the high temperature of the silica sol itself, but also removes bubbles in the silica sol. The mold component is located below the output end of the discharging component.

[0009] Furthermore, the storage component includes a storage bin and a cover plate. The storage bin shell is provided with a cavity, and an annular conductor block is provided in the cavity. The annular conductor block is sleeved on the storage bin and electrically connected to an external power supply. A discharge port is provided on one side of the storage bin, and a connecting piece is provided outside the discharge port. The connecting piece is fixedly connected to the bottom end of the storage bin, and the cover plate is snap-connected to the top end of the storage bin.

[0010] A discharge port is provided on one side of the storage bin, which is the output end. A cavity is provided on the outer wall of the storage bin, and the cavity and the storage bin are on the same central axis. An annular conductor block is provided in the cavity, and the annular conductor block is used to eliminate bubbles in the silica sol inside the storage bin. The principle is that after a positive charge is introduced into the annular conductor block, the silica sol particles in the silica sol will be pulled. The surface of the silica sol particles usually carries a negative charge, and thus they move in a directional circular motion under the traction of the annular conductor block, ultimately achieving a stirring effect and reducing the generation of bubbles. The bottom end of the cover plate cooperates with the top of the storage bin, and the cover plate is used to seal the storage bin and reduce the temperature loss rate of the silica sol. A feed port is provided at the top of the storage bin, which is connected to an external pipeline, thereby reducing the area of ​​contact between the silica sol and the external air and reducing the probability of bubbles and impurities in the silica sol.

[0011] Furthermore, the discharge component includes a discharge pipe and a main conductor plate. The input end of the discharge pipe is connected with the output end of the storage bin. The discharge pipe is fixedly connected to the connecting piece. Main conductor plates are provided at the upper and lower ends of the discharge pipe. The main conductor plate is fixedly connected to the discharge pipe. A diversion pipe is provided at the end of the discharge pipe away from the input end. The diversion pipe is connected with the discharge pipe. The diversion pipe has three output ends. Auxiliary conductor plates are provided at the upper and lower ends of the diversion pipe. The auxiliary conductor plates are fixedly connected to the diversion pipe. The main conductor plate and the auxiliary conductor plate are wrapped with a shell. A guide groove is provided inside the diversion pipe. The guide groove is used to reduce the flow rate of the silica sol. A detection component is provided at the output end of the diversion pipe. The detection component is used to detect the flow rate of the silica sol.

[0012] The discharge component acts as a transport pipeline located at the bottom of the storage bin. The discharge pipe is fixedly connected to the connector and is connected to the output end at the bottom of the storage bin. The discharge pipe is a single pipe and the diversion pipe is a three-pipe diversion pipe. The conductor plate is connected to an external power supply to generate positive charge. The surface of the silica sol particles carries a charge, usually a negative charge, forming a double electric layer structure. Under the action of the external electric field, that is, the conductor plate, the charged particles will move toward the electrode of opposite charge. By controlling the direction and intensity of the electric field, the flow of particles in the silica sol can be regulated. The effect achieved is that by adjusting the intensity of the electric field, the migration speed of the particles can be controlled, thereby adjusting the flow direction and speed of the silica sol. At low voltage , the electric field strength is low, the flow speed of the silica sol is slow, the slower the flow speed, the smaller the flow rate; under high voltage, the electric field strength increases, the flow speed is accelerated, the faster the flow speed, the greater the flow rate, the main conductor plate and the auxiliary conductor plate have the same principle, and the number of auxiliary conductor plates is consistent with the number of output ends of the shunt tube, so that by adjusting the electric field strength of the auxiliary conductor plate, a plurality of silica sol output ends with different flow rates can be achieved. The detection component is used to detect the flow rate of the shunt tube and change the electric field strength of the conductor plate according to the detected flow rate. The guide groove is wavy, so when the conductor plate guides the silica sol, its guide groove also affects the flow direction of the silica sol, thereby helping to slow down the flow rate of the silica sol and reduce the probability of splashing during pouring.

[0013] Furthermore, the detection component includes a coil and electrodes. The coil is sleeved at the output end of the shunt tube, and electrodes are provided on both sides of the coil.

[0014] The coil and the shunt pipe are on the same central axis. The coil is used to detect the flow rate of silica sol. The principle is that when the silica sol flows through the coil, the fluid will cut the magnetic lines of force, thereby generating an induced electromotive force in the fluid. The flow rate of the silica sol is known by the size of the induction motor. The size of the induced electromotive force is proportional to the flow rate of the fluid, the magnetic field strength and the pipe diameter. When the magnetic field strength and the pipe diameter remain unchanged, the flow rate and the induced electromotive force are linearly related. The electrodes are used to capture the induced electromotive force. The electrodes are electrically connected to an external converter to convert the induced electromotive force into a flow value.

[0015] Furthermore, the desktop assembly includes a base and a work surface. The base is located on the horizontal ground. A support column is provided on the upper surface of the base. The support column is fixedly connected to the upper surface of the base. A work surface is provided on the top of the support column. The work surface is fixedly connected to the support column. The work surface is provided with a conveyor belt, and a mold assembly is provided on the conveyor belt.

[0016] The desktop assembly serves as a support column to place the mold assembly at the output end of the discharge assembly. The support column is vertically fixedly connected to the base, and the top of the support column is fixedly connected to the work surface. A conveyor belt is provided on the surface of the work surface. The conveyor belt is used to drive multiple mold assemblies, thereby facilitating rapid casting of multiple molds.

[0017] Furthermore, the mold assembly includes an upper mold and a lower mold. The lower mold is located on the upper surface of the conveyor belt. The upper mold is provided on the top of the lower mold. The upper mold and the lower mold are clamped and connected. A pouring port is provided on the top of the upper mold. A splash guard is provided outside the pouring port. The splash guard is fixedly connected to the upper mold. A temperature control assembly is provided outside the lower mold.

[0018] The mold assembly is used to receive the silica sol at the output end of the discharge assembly and form the silica sol inside the mold. The lower mold is located on the conveyor belt and moves through the conveyor belt to achieve rapid movement of multiple molds, thereby facilitating rapid casting of multiple molds. The upper mold is connected to the lower mold by clipping. The pouring port of the upper mold serves as the input end of the mold assembly. The splash-proof block is located at the pouring port of the upper mold. During the previous transportation process, the bubbles were eliminated by the action of the annular conductor block, and the conductor plate achieved a drainage effect. The conductor plate achieves drainage and speed control effects on the silica sol through electric charge. Therefore, when the silica sol reaches the mold, its flow rate and pores are controlled, thereby effectively achieving a splash-proof effect. The temperature control assembly is used to control the silica sol in the mold.

[0019] Furthermore, a clamping block is provided on the outer wall of the lower mold, which is fixedly connected to the lower mold. A clamping groove is provided on the outer wall of the upper mold, and the clamping block cooperates with the clamping groove. A cavity is provided in the clamping block, and a bimetallic strip is provided in the cavity. One end of the bimetallic strip is fixedly connected to the inner wall of the clamping block, and a main contact block is provided at the other end of the bimetallic strip, and an auxiliary contact block is provided in the cavity.

[0020] The clamping block is located on the outer wall of the lower mold. There are four clamping blocks, and they are all fixedly connected to the outer wall of the lower mold. A clamping groove is provided at the bottom of the upper mold. The clamping block cooperates with the clamping groove. Due to the clamping groove structure, the gap between the upper mold and the lower mold is irregular, which can effectively prevent the leakage of the internal silica sol temperature. A cavity is provided in the clamping block, and a bimetallic strip is provided in the cavity. One end of the bimetallic strip is fixedly connected to the inner wall of the clamping block. When the mold is filled with silica sol, the temperature of the silica sol itself will affect the bimetallic strip. The principle is that when the temperature rises, the metal layer with a larger expansion coefficient will expand more, while the metal layer with a smaller expansion coefficient will expand less. This difference will cause the bimetallic strip to bend toward the side with a smaller expansion coefficient. After the silica sol is formed, the temperature will drop, and the bimetallic strip will bend toward the side with a larger expansion coefficient and eventually return to its initial state. When the temperature rises, when the bimetallic strip bends, the distance between the main contact block and the auxiliary contact block will change. As the distance increases, the resistance value will increase; and when the distance decreases, the resistance value will decrease.

[0021] Furthermore, the temperature control component includes a main semiconductor and a secondary semiconductor. The outer walls of the upper mold and the lower mold are provided with a groove body, the main semiconductor is provided in the groove body, and the main semiconductor is fixedly connected to the inner wall of the groove body. The secondary semiconductor is located on the side of the groove body away from the main semiconductor, and the secondary semiconductor is fixedly connected to the inner wall of the groove body.

[0022] The temperature control component is used to control the temperature of the silica sol in the mold, in which the main semiconductor and the secondary semiconductor are connected by wires to form a circuit. The main semiconductor and the secondary semiconductor are two different semiconductors. Therefore, when current passes through the circuit composed of two different semiconductors, heat absorption and heat release phenomena will occur at the contact point. The principle is that when electrons jump from low energy level to high energy level, they absorb heat and form a cold end, and when electrons jump from high energy level to low energy level, they release heat and form a hot end. The cooling and heating functions can also be switched by changing the direction of current. The temperature control component is controlled by the temperature value detected by the bimetallic strip. The process is that when the silica sol enters the mold, the temperature control component is first used to maintain the overall temperature of the mold to be the same to prevent temperature differences. When the silica sol is filled, the temperature control component is used to cool the entire silica sol in the mold to form.

[0023] Furthermore, a rotating assembly is provided at the bottom of the storage bin, and the rotating assembly includes a column and a rotating motor. The column is located on the upper surface of the base, and the column is fixedly connected to the base. There are two columns, and a storage bin is provided between the columns. The column is rotatably connected to the storage bin, and a rotating motor is provided on one side of the column. The fixed end of the rotating motor is located on the side of the column away from the storage bin, the fixed end of the rotating motor is fixedly connected to the column, and the output end of the rotating motor is fixedly connected to the storage bin.

[0024] Specifically, the rotating assembly is used to control the tilt of the storage bin, so that the silica sol in the storage bin flows to the discharge assembly, and then flows to the mold through the discharge assembly to realize the casting process. The column is vertically fixedly connected to the base. There are two columns. A storage bin is provided between the two columns. The column is rotatably connected to the outer wall of the storage bin. The fixed end of the rotating motor is fixedly connected to the column. The rotating motor is located on the side of the column away from the storage bin. The output end of the rotating motor passes through the column and is connected to the storage bin. The output end of the rotating motor is fixedly connected to the outer wall of the storage bin. The rotating motor is used as a power source to control the tilt of the storage bin.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The annular conductor block in the present invention is used to eliminate bubbles in the silica sol inside the storage bin. After the annular conductor block is charged with positive charge, it will pull the silica sol particles in the silica sol, so that they move in a directional circular motion under the traction of the annular conductor block, ultimately achieving a stirring effect and reducing the generation of bubbles.

[0027] 2. In the present invention, the conductor plate is connected to an external power supply to generate positive charge. The surface of the silica sol particles carries a charge, usually a negative charge, forming a double-layer structure. Under the action of the external electric field, that is, the conductor plate, the charged particles will move toward the electrode with the opposite charge. The effect achieved is that by adjusting the electric field strength, the migration speed of the particles can be controlled, thereby adjusting the flow direction and speed of the silica sol.

[0028] 3. In the present invention, the conductor plate and the diversion pipe are matched to effectively control the flow rate and flow of the silica sol in the discharge component. The coil is used to detect the flow rate of the silica sol, so that the electric field size of the conductor plate changes through the induced electricity generated by the coil. Under the drainage of the conductor plate, the silica sol flowing out reaches the set value.

[0029] 4. When the silica sol is poured into the mold, the present invention detects the mold temperature through the principle that the bimetallic strip will be deformed by temperature, and then the main semiconductor and the auxiliary semiconductor work to maintain the entire mold at the same temperature. The temperature of the mold is then adjusted by the flow rate detected by the coil. When pouring the silica sol, the semiconductor is used to maintain the temperature. After the silica sol is poured, the semiconductor is used to cool the entire mold, thereby improving molding efficiency and casting quality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention. Example

[0043] like Figures 1 to 11 As shown, the present invention provides a quantitative casting type casting equipment for investment silica sol and a casting process technology solution. The forging equipment includes a desktop component 1, a storage component 2 and a temperature control component 3. The bottom end of the storage component 2 is provided with a discharge component 4, and the output end of the discharge component 4 is provided with a mold component 5. The mold component 5 is located above the desktop component 1. The discharge component 4 is used to control the flow rate of the silica sol. The mold component 5 is provided with a temperature control component 3, and the temperature control component 3 is used to quickly cool the mold.

[0044] Specifically, the desktop component 1 is used to transport and place the mold component 5. The mold component 5 is used to shape the silica sol, and then the silica sol in the mold is cooled by the temperature control component 3 on the mold component 5. The temperature control component 3 is used to quickly shape the silica sol, and can also eliminate the bubbles in the silica sol, thereby improving the molding accuracy of the casting and the service life (effect) of the mold. The storage component 2 is used to store high-temperature silica sol and pour it at the input end of the module component through the discharge component 4. The silica sol will produce bubbles during the transportation process, which will cause pores on the surface or inside of the casting when the silica sol is molded. These pores will affect the appearance quality of the casting. The storage component 2 not only maintains the high temperature of the silica sol itself, but also removes the bubbles in the silica sol. The mold component 5 is located below the output end of the discharge component 4.

[0045] like Figures 1 to 4As shown, the storage assembly 2 includes a storage bin 21 and a cover 22. The outer shell of the storage bin 21 is provided with a cavity 211. The cavity 211 is provided with an annular conductor block 23. The annular conductor block 23 is sleeved on the storage bin 21. The annular conductor block 23 is electrically connected to an external power supply. A discharge port 212 is provided on one side of the storage bin 21. A connector 24 is provided outside the discharge port 212. The connector 24 is fixedly connected to the bottom end of the storage bin 21, and the cover 22 is snap-connected to the top end of the storage bin 21.

[0046] Specifically, a discharge port 212 is provided on one side of the storage bin 21, which is the output end. A cavity 211 is provided on the outer wall of the storage bin 21. The cavity 211 and the storage bin 21 are on the same central axis. An annular conductor block 23 is provided in the cavity 211. The annular conductor block 23 is used to eliminate bubbles in the silica sol inside the storage bin 21. The principle is that after the annular conductor block 23 is introduced with positive charge, it will pull the silica sol particles in the silica sol. The surface of the silica sol particles usually carries a negative charge, so that they move in a directional circular motion under the traction of the annular conductor block 23, and finally achieve a stirring effect and reduce the generation of bubbles. The bottom end of the cover 22 cooperates with the top of the storage bin 21. The cover 22 is used to seal the storage bin 21 and reduce the temperature loss rate of the silica sol. A feed port is provided at the top of the storage bin 21, which is connected to an external pipeline, so as to reduce the area of ​​contact between the silica sol and the external air and reduce the probability of bubbles and impurities in the silica sol.

[0047] like Figures 6 to 8 As shown, the discharge component 4 includes a discharge pipe 41 and a main conductor plate 42. The input end of the discharge pipe 41 is connected to the output end of the storage bin 21. The discharge pipe 41 is fixedly connected to the connecting piece 24. The upper and lower ends of the discharge pipe 41 are provided with main conductor plates 42. The main conductor plate 42 is fixedly connected to the discharge pipe 41. The end of the discharge pipe 41 away from the input end is provided with a diverter pipe 45. The diverter pipe 45 is connected to the discharge pipe 41. The diverter pipe 45 has three output ends. The upper and lower ends of the diverter pipe 45 are provided with auxiliary conductor plates 43. The auxiliary conductor plate 43 is fixedly connected to the diverter pipe 45. The main conductor plate 42 and the auxiliary conductor plate 43 are wrapped with a shell 44. A guide groove 451 is provided inside the diverter pipe 45. The guide groove 451 is used to reduce the flow rate of the silica sol. The output end of the diverter pipe 45 is provided with a detection component 6. The detection component 6 is used to detect the flow rate of the silica sol.

[0048] Specifically, the discharge component 4 acts as a transport pipeline located at the bottom of the storage bin 21, the discharge pipe 41 is fixedly connected to the connector 24, and the discharge pipe 41 is connected to the output end at the bottom of the storage bin 21. The discharge pipe 41 is a single pipeline, and the diversion pipe 45 is a three-pipeline that acts as a diversion. The conductor plate is connected to an external power supply to generate positive charge. The surface of the silica sol particles carries a charge, usually a negative charge, forming a double electric layer structure. Under the action of the external electric field, that is, the conductor plate, the charged particles will move toward the electrode 62 of the opposite charge. By controlling the direction and strength of the electric field, the flow of particles in the silica sol can be regulated, and the effect achieved is that by adjusting the electric field strength, the particles can be controlled. The migration speed is adjusted to adjust the flow direction and speed of the silica sol. Under low voltage, the electric field strength is low, and the flow speed of the silica sol is slow. The slower the flow speed, the smaller the flow rate. Under high voltage, the electric field strength increases, the flow speed is accelerated, and the faster the flow speed, the larger the flow rate. The main conductor plate 42 and the auxiliary conductor plate 43 are based on the same principle. The number of auxiliary conductor plates 43 is consistent with the number of output ends of the shunt tube 45. Therefore, by adjusting the electric field strength of the auxiliary conductor plate 43, multiple silica sol output ends with different flow rates can be achieved. The detection component 6 is used to detect the flow rate of the shunt tube 45 and change the electric field strength of the conductor plate according to the detected flow rate. It should be supplemented that the conductor plate refers to the main conductor plate 42 and the auxiliary conductor plate 43.

[0049] like Figure 8 As shown, the detection assembly 6 includes a coil 61 and an electrode 62 . The coil 61 is sleeved at the output end of the shunt tube 45 , and electrodes 62 are provided on both sides of the coil 61 .

[0050] Specifically, the coil 61 and the shunt tube 45 are on the same central axis. The coil 61 is used to detect the flow rate of the silica sol. The principle is that when the silica sol flows through the coil 61, the fluid will cut the magnetic lines of force, thereby generating an induced electromotive force in the fluid. The flow rate of the silica sol is known by the size of the induction motor, where the size of the induced electromotive force is proportional to the flow rate of the fluid, the magnetic field strength and the pipe diameter. When the magnetic field strength and the pipe diameter remain unchanged, the flow rate and the induced electromotive force are linearly related. The electrode 62 is used to capture the induced electromotive force. The electrode 62 is electrically connected to an external converter to convert the induced electromotive force into a flow value.

[0051] like Figure 1 、 Figure 2 As shown, the desktop assembly 1 includes a base 11 and a work surface 12. The base 11 is located on the horizontal ground. A support column 14 is provided on the upper surface of the base 11. The support column 14 is fixedly connected to the upper surface of the base 11. A work surface 12 is provided on the top of the support column 14. The work surface 12 is fixedly connected to the support column 14. The work surface 12 is provided with a conveyor belt 13. The conveyor belt 13 is provided with a mold assembly 5.

[0052] Specifically, the desktop assembly 1 serves as a support column 14 to place the mold assembly 5 at the output end of the discharge assembly 4. The support column 14 is vertically fixedly connected to the base 11. The top of the support column 14 is fixedly connected to the work table 12. A conveyor belt 13 is provided on the surface of the work table 12. The conveyor belt 13 is used to drive multiple mold assemblies 5, thereby facilitating the rapid casting of multiple molds.

[0053] like Figures 9 to 11 As shown, the mold assembly 5 includes an upper mold 51 and a lower mold 52. The lower mold 52 is located on the upper surface of the conveyor belt 13. The upper mold 51 is provided on the top of the lower mold 52. The upper mold 51 and the lower mold 52 are clamped and connected. A pouring port 511 is provided on the top of the upper mold 51. A splash-proof block 53 is provided outside the pouring port 511. The splash-proof block 53 is fixedly connected to the upper mold 51. A temperature control component 3 is provided outside the lower mold 52.

[0054] Specifically, the mold assembly 5 is used to receive the silica sol at the output end of the discharge assembly 4 and form the silica sol inside the mold. The lower mold 52 is located on the conveyor belt 13 and moves through the conveyor belt 13 to achieve rapid movement of multiple molds, thereby facilitating rapid casting of multiple molds. The upper mold 51 is connected to the lower mold 52 by snapping. The pouring port 511 of the upper mold 51 serves as the input end of the mold assembly 5. The splash-proof block 53 is located at the pouring port 511 of the upper mold 51. Because the bubbles were eliminated due to the action of the annular conductor block 23 during the previous transportation process, and the conductor plate achieved a drainage effect, the conductor plate achieved a drainage and speed control effect on the silica sol through electric charge. Therefore, when the silica sol reaches the mold, its flow rate and pores are controlled, which can effectively achieve a splash-proof effect. The temperature control assembly 3 is used to control the silica sol in the mold.

[0055] like Figure 10 As shown, the outer wall of the lower mold 52 is provided with a clamping block 54, and the clamping block 54 is fixedly connected to the lower mold 52. The outer wall of the upper mold 51 is provided with a clamping groove, and the clamping block 54 cooperates with the clamping groove. A cavity is provided in the clamping block 54, and a bimetallic strip 55 is provided in the cavity. One end of the bimetallic strip 55 is fixedly connected to the inner wall of the clamping block 54, and the other end of the bimetallic strip 55 is provided with a main contact block 56, and an auxiliary contact block 57 is provided in the cavity.

[0056] Specifically, the clamping block 54 is located on the outer wall of the lower mold 52. There are four clamping blocks 54, and they are all fixedly connected to the outer wall of the lower mold 52. A clamping groove is provided at the bottom end of the upper mold 51, and the clamping block 54 cooperates with the clamping groove. Due to the clamping groove structure, the gap between the upper mold 51 and the lower mold 52 is irregular, which can effectively prevent the leakage of the internal silica sol temperature. A cavity is provided in the clamping block 54, and a bimetallic strip 55 is provided in the cavity. One end of the bimetallic strip 55 is fixedly connected to the inner wall of the clamping block 54, so that when the mold is filled with silica sol, the temperature of the silica sol itself will affect the bimetallic strip 55. The principle is that when the temperature rises, the metal layer with a larger expansion coefficient will expand more, while the metal layer with a smaller expansion coefficient will expand less. This difference will cause the bimetallic strip 55 to bend toward the side with a smaller expansion coefficient. After the silica sol is formed, the temperature will drop, and the bimetallic strip 55 will bend toward the side with a larger expansion coefficient, and eventually return to its initial state. When the temperature rises, the bimetallic strip 55 bends, and the distance between the main contact block 56 and the auxiliary contact block 57 will change. As the distance increases, the resistance value will increase; and when the distance decreases, the resistance value will decrease.

[0057] like Figure 11 As shown, the temperature control component 3 includes a main semiconductor 31 and a secondary semiconductor 32. A groove is provided on the outer walls of the upper mold 51 and the lower mold 52. The main semiconductor 31 is provided in the groove. The main semiconductor 31 is fixedly connected to the inner wall of the groove. The secondary semiconductor 32 is located on the side of the groove away from the main semiconductor 31. The secondary semiconductor 32 is fixedly connected to the inner wall of the groove.

[0058] Specifically, the temperature control component 3 is used to control the temperature of the silica sol in the mold, wherein the main semiconductor 31 and the secondary semiconductor 32 are connected by wires to form a loop. The main semiconductor 31 and the secondary semiconductor 32 are two different semiconductors. Therefore, when the current passes through the loop composed of two different semiconductors, heat absorption and heat release phenomena will occur at the contact point. The principle is that when electrons jump from a low energy level to a high energy level, they absorb heat and form a cold end, and when electrons jump from a high energy level to a low energy level, they release heat and form a hot end. The cooling and heating functions can also be switched by changing the direction of the current. The temperature control component 3 is controlled by the temperature value detected by the bimetallic strip 55. The process is that when the silica sol enters the mold, the temperature control component 3 is first used to maintain the mold temperature. When the silica sol is filled, the temperature control component 3 is used to cool the mold for molding.

[0060] Specifically, the rotating component 7 is used to control the tilt of the storage bin 21, so that the silica sol in the storage bin 21 flows to the discharge component 4, and then flows to the mold through the discharge component 4 to realize the casting process. The column 71 is vertically fixedly connected to the base 11. There are two columns 71. A storage bin 21 is provided between the two columns 71.
