Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of casting and forming of cold-setting materials in metallurgical technology, and particularly relates to a rotary casting and forming system and method for cold-setting materials. Background Art
[0002] In industry, for the ingot forming of cold-setting materials, large mold cavity molds are generally used for casting. For example, for the production of industrial silicon (Si), calcium carbide (CaC), sodium sulfide (Na2S), etc., the molten liquid materials made by smelting are usually first introduced from the smelting furnace into a large high-temperature water ladle, and then poured into the cavity of a single mold through the water ladle, so as to process products with a preset shape. The properties of the cold-setting materials require strict control of the casting time. For example, industrial silicon is in a liquid state when its temperature is higher than the melting point of 1410 °C, but it will quickly turn into a solid state when its temperature drops below the melting point. Therefore, to avoid solidification during casting, the water ladle should have a sufficient heat capacity, so its volume is huge. At the same time, to ensure smooth pouring and easy cleaning, a relatively large nozzle size must also be equipped. These factors make it difficult to accurately operate the small-sized mold cavity during casting, and the production efficiency is low. Therefore, the specifications of large-scale ingots in these industries are generally above 1 m, usually reaching 2 - 3 m or even larger, and they cannot be provided as raw materials for downstream use. Therefore, the materials must be processed by multiple crushing operations to become raw materials or commodities.
[0003] When some prior technologies solve the above problems, small-sized molds are designed, and small nozzles are used to carry molten materials for casting to obtain small-sized products. However, this method has obvious disadvantages:
[0004] 1. High risk. It is necessary to move the water ladle carrying the molten materials and perform casting during the movement. It is difficult to control the liquid output of the nozzle, and even overflow and leakage may occur. Moreover, the temperature of the molten materials is extremely high, posing a great safety hazard. Small-flow casting makes the water storage time of the water ladle long, and the molten materials are prone to crystallization or solidification in the water ladle, resulting in blockage of the watering nozzle, and even scrapping of the water ladle lining and materials.
[0005] 2. Harsh working environment. The radiant heat of the molten materials is extremely strong, which has a great impact on the ambient temperature during casting. The volatile elements in the materials are released during casting, polluting the air, making the production environment extremely harsh, and causing great harm to the physical and mental health of the operators.
[0006] 3. Unable to continuously pour water for casting and low efficiency. The number of casting molds is large, and the laying occupies a large area in the workshop. Moreover, the processes of laying, casting, demolding, cleaning, and transporting for each single casting mold are carried out manually one by one, consuming a large amount of manpower and having low production efficiency.
[0007] 4. Difficult quality control and increased losses. Since the operation is mainly manual and there are many influencing factors, the process randomness is relatively large during the casting process, and situations such as overcasting, undercasting, and large-area overflow are likely to occur. The quality control during the production process is difficult and the losses are large. It can be seen that there is still room for urgent improvement in the casting technology for large-scale casting of small-sized cold-setting products. Optimization should be carried out to improve the safety, accuracy, and automation of casting to improve the production environment and reduce consumption. Therefore, a more reasonable technical solution needs to be proposed to solve the technical problems existing in the prior art. Summary of the Invention
[0008] To at least overcome one of the above-mentioned defects, the present invention proposes a rotary casting forming system and method for cold-setting materials. By setting an annular mold and realizing continuous casting production in a rotary casting manner, while ensuring the accurate product size and stable quality, it reduces material waste, reduces labor losses, and improves the convenience of demolding operations.
[0009] To achieve the above object, the rotary casting structure disclosed in the present invention can adopt the following technical solutions:
[0010] A rotary casting forming system for cold-setting materials, comprising:
[0011] A ring mold body, the ring mold body is circular, and a plurality of mold cavities are formed between its inner side surface and outer side surface. The mold cavities are continuously and evenly arranged along the circumference, and adjacent mold cavities are separated by templates. The height of the templates is lower than the heights of the inner side surface and outer side surface of the ring mold body;
[0012] A mold table for setting the ring mold body, and the mold table rotates coaxially with the ring mold body;
[0013] A support assembly for supporting the mold table and the ring mold body and performing rotation; the support assembly includes a support wheel set for supporting the mold table from below, and an adjustment wheel set for pushing from the side to adjust the rotation center of the mold table;
[0014] A drive assembly for driving the mold table and the ring mold body to rotate;
[0015] An equipment foundation, including an inclined foundation surface, and the support assembly and the drive assembly are both arranged on the equipment foundation;
[0016] A mobile working platform for carrying the molten material container to the casting position, and is provided with a heat recovery assembly for recovering the heat released during the condensation of the molten material.
[0017] The above-mentioned disclosed rotary casting structure realizes rotary continuous casting through an annular die structure, that is, in production, the ring die body is kept in a rotating state, the mold cavity of the ring die body is cast from above, and continuous casting can be realized by using the rotation of the ring die body. The flow rate of the casting liquid and the rotation rate are reasonably set, and material forming and cooling and demolding are realized before one full rotation is completed, and then continuous cyclic casting can be realized to maintain continuous production. In this way, the requirements for the space of the production workshop are greatly reduced, and the manual placement and demolding processes of the mold are also avoided. The casting container also remains in a fixed position without bearing movement, so that the production efficiency can be improved and the production safety can also be improved.
[0018] The ring die body is inclined. When the injection amount at the casting position reaches the full mold, it will automatically overflow to the mold cavity at the lower position, so as to ensure that each mold cavity is filled. The water outlet of the molten material container can always be kept open for continuous casting, and the control of the casting amount can be realized without opening and closing control, thus greatly simplifying the operation and improving the quality of the ingot.
[0019] In the present invention, the mobile working platform carries the molten material container above the ring die body and performs casting while the ring die body rotates; the same mobile platform can be combined with multiple arranged ring die devices for casting.
[0020] Furthermore, in the present invention, the ring die body is driven to rotate by the mold table. The structure of the mold table can be constructed in various forms and is not uniquely limited. Here, one feasible option is optimized and proposed: the mold table includes an annular casting table. The upper part of the casting table is connected to the ring die body in a matching manner. A rotating ring is arranged in a matching manner at the lower part of the casting table. The bottom surface of the rotating ring is in rolling cooperation with the support wheel set, and the side surface of the rotating ring is in abutting cooperation with the adjusting wheel set. When such a scheme is adopted, the ring die body can also be connected above the casting table through a ring-shaped frame, and components such as demolding ejector rods can be arranged in the space structure of the ring-shaped frame; the lower part of the casting table can also be connected and matched with the supporting component through the ring-shaped frame, and the ring-shaped frame is used to arrange structures such as the rotating ring and the driving pin of the driving component.
[0021] Furthermore, in order to better support the rotation of the support assembly and adjust the rotation center, an optimization is carried out here and a structure of an adjustment wheel set is proposed: The adjustment wheel set includes a number of adjustment arms arranged along the circumference and deflected in the radial direction. An adjustment wheel for abutting against the rotary ring is arranged on the adjustment arm. The adjustment arm cooperates with a push-pull adjustment member and adjusts the deflection angle through the push-pull adjustment member. When adopting such a scheme, the adjustment wheel can be arranged inside the rotary ring, and a tightening force is applied outward in the radial direction, so as to adjust the rotation center of the rotary ring. At the same time, the support wheel set also includes a number of support wheels evenly spaced along the circumference, which are correspondingly arranged with the rotary ring and provide rolling support. In some schemes, the support assembly further includes a support frame, which is arranged on the equipment foundation and is used to connect and install the support wheel set and the adjustment wheel set.
[0022] Further, in the present invention, the rotation of the ring die body is realized through a driving member. The structure of the driving member is not uniquely limited. An optimization is carried out here and a feasible option is proposed: The driving member includes a driver, a driving gear is arranged on the output shaft of the driver, and a number of driving pins are evenly spaced along the circumference under the mold table. The driving gear meshes with the driving pins for transmission. When adopting such a scheme, the driving member can adopt a driving motor, and the driving gear meshes with the driving pins to realize transmission; when the driving pins are damaged and deformed after long-term use, the transmission ability can be restored by replacing the driving pins.
[0023] Furthermore, in order to avoid damage caused by the pouring speed being too fast and the molten material spilling, an optimization is carried out here and a feasible option is proposed: An annular overflow groove for receiving the molten material overflowing from the ring die body is arranged on the mold table, and a safety overflow groove for receiving the molten material overflowing from the annular overflow groove is further arranged on the equipment foundation. When adopting such a scheme, the annular overflow groove and the safety overflow groove can receive the spilled and overflowed molten material, prevent it from spreading everywhere and causing damage, and improve the fault tolerance and safety of the equipment.
[0024] Furthermore, during demolding, the present invention realizes automatic demolding by means of jacking demolding. Specifically, an optimization is carried out here and a feasible option is proposed as follows: A demolding hole is arranged at the bottom of the mold cavity, a demolding ejector rod is arranged below the ring die body and the demolding ejector rod extends into the mold cavity from the demolding hole, and a discharging assembly for jacking the demolding ejector rod is arranged on the support assembly. The products ejected from the mold cavity slide into the discharging table for subsequent processing. When adopting such a scheme, multiple mold cavities can be demolded synchronously, improving the demolding efficiency and convenience.
[0025] Further, in order to prevent the molten material from leaking out of the demolding hole, the structure of the template can be optimized. The method is not uniquely limited. Here, an optimization is carried out and one feasible option is proposed: a demolding hole is provided at the bottom of the mold cavity, and a demolding ejector rod is arranged in cooperation with the demolding hole. During casting, the demolding ejector rod makes a closed fit with the demolding hole, and when demolding is required, the demolding ejector rod rises and pushes out the cooled and formed product from the mold cavity.
[0026] Furthermore, an inclined transition surface is formed between the demolding hole and the bottom of the mold cavity.
[0027] Further, in order to improve the continuous operation ability of the rotary casting equipment, an optimization is carried out here and a feasible option is proposed: a cooling component and a demolding agent spraying component are also arranged outside the ring die body. When such a scheme is adopted, the cooling component includes an air cooling component for cooling the ring die body and the molten material before demolding. It also includes a water cooling component for cooling the ring die body after demolding; the demolding agent spraying component is used to spray the mold cavity after demolding to form an interface coating on the surface of the mold cavity, so that the molten material is easy to separate, and the surface of the mold is smooth and clean.
[0028] Further, in the present invention, the mold cavity is used to accommodate the molten material and serve as a space for its cooling and forming. In order to facilitate demolding after solidification, the structure of the mold cavity can be constructed in various forms, which is not uniquely limited. Here, the structure of the mold cavity is optimized and one feasible option is proposed: the diameter of the mold cavity gradually increases from the cavity bottom to the cavity opening, and the inner walls of the mold cavity are designed with slopes on all four sides. When such a scheme is adopted, when the molten material cools, it will shrink towards the core, reducing the locking force. At the same time, the tapered opening formed by the inclined surface is in the same direction as the discharging direction, and the demolding force is small.
[0029] Further, in order to meet the requirements of the actual production scale, the layout of the mold cavity can be optimized. The method is not uniquely limited. Here, an optimization is carried out and one feasible option is proposed: the mold cavity is provided with several layers and is arranged sequentially outward along the circumference of the ring die body to form an annular distribution. When such a scheme is adopted, both the inner layer mold cavity and the outer layer mold cavity can realize casting and cooling and forming. When larger-scale casting production is required, the diameter of the ring die body is increased and more layers of mold cavities are set. When casting, the molten material is simultaneously cast into the multi-layer mold cavities, and then synchronous cooling and forming and synchronous demolding can be carried out, thereby improving the production efficiency.
[0030] Further, when distributing the mold cavities of different rings, an optimized setting can also be carried out. Here, one feasible option is proposed: the corresponding mold cavities on adjacent rings are located on the same radius line. When such a scheme is adopted, the volumes of adjacent mold cavities are the same, and the casting amount can be synchronously controlled during casting, which is convenient for simplifying the casting control process.
[0031] Furthermore, in the present invention, the structure of the ring mold body is optimized and one of the feasible options is proposed: the width of the upper casting surface of the ring mold body is smaller than the width of the lower part of the ring mold body, so that the outer side of the ring mold body forms an inclined surface. When such a solution is adopted, the inner and outer sides of the ring mold body are higher than the height of the template to prevent the molten material from overflowing. However, when the casting volume is too large and exceeds the capacity limit of the mold cavity, the molten material overflows and can be guided along the outer inclined surface of the ring mold body to the safety buffer groove below, thereby reducing the damage caused by the overflow of the molten material and improving the safety of casting.
[0032] Furthermore, in the present invention, the structure of the mobile working platform is not limited to a single one, and an optimization is made here and one of the feasible options is proposed: the mobile working platform is provided with a mechanism to drive the molten material container to move, the molten material container is provided with a quick-release discharge port, and an opening regulator corresponding to the discharge port is also provided. When such a scheme is adopted, the opening regulator is used to adjust the flow rate of the fluid material, so as to achieve the best casting effect in coordination with the rotation of the ring die body.
[0033] The above content discloses a casting system. The present invention also discloses a casting method, which is described in the following content:
[0034] A rotary casting method for cold-setting materials, comprising:
[0035] Preheat the material to a molten state, receive it through a molten material container and move it to the top of the ring die body;
[0036] The ring die body is rotated and reaches the initial casting speed, at which time casting begins, and the molten material is lowered from the container and enters the mold cavity of the ring die body after being homogenized. After the ring die body rotates through the set angle, the ring die body and the molten material are cooled;
[0037] The flow rate of the molten material and / or the rotation speed of the ring die body are adjusted so that the amount of the molten material cast into the mold cavity reaches a set range, and the molten material is cooled and formed into a product when the ring die body rotates to a set angle;
[0038] The cooled and formed product is demoulded from the bottom of the ring die body, and the demoulded product enters the subsequent conveying process;
[0039] After the ring mold body is demoulded, it continues to rotate and the mold cavity after demoulding is cooled and sprayed with a release agent. When it rotates back to the bottom of the material container, casting is performed again.
[0040] Further, the molten material of the present invention is a high-temperature substance, which releases a large amount of heat during the cooling and forming process. In order to reduce heat loss and recycle the heat, optimization has been carried out here and one feasible option is proposed: the heat released during the cold solidification of the molten material after the casting of the ring die body is exchanged through air flow, and the heated hot air material passes through the heat recovery component to reuse the heat. When adopting such a scheme, the heat recovery component includes a cooling air nozzle and a heat collecting cover. The heat collecting cover transports the heat exchange air to a set position through an air guiding pipe, and the hot air can be transported to the furnace as auxiliary heat for the preheating treatment of the material.
[0041] Compared with the prior art, some beneficial effects of the disclosed technical solution of the present invention include:
[0042] In the present invention, by utilizing the rotation of the ring die body, continuous operations such as casting, cooling and forming, demoulding, discharging, conveying, and mold cooling circulation are realized. This not only improves the production efficiency and safety, enhances the standardization and automation of production, but also reduces the demand for production area, lowers the labor intensity, and improves the material utilization rate.

[0054] The present invention will be further explained below with reference to the drawings and specific embodiments.
[0055] In view of many problems existing in the prior art, such as low production process efficiency, poor environment, and poor production quality, the following embodiments optimize the mold to solve the problems existing in the prior art.
[0056] Embodiment 1
[0057] As Figures 1 to 3 shown, this embodiment provides a rotary casting molding system for cold-setting materials, and one of its structures includes:
[0058] A ring die body 1, the ring die body 1 is circular, and a plurality of mold cavities 105 are formed between its inner side surface 102 and outer side surface 101. The mold cavities 105 are arranged continuously and evenly along the circumference, and adjacent mold cavities 105 are separated by a template 103. The height of the template 103 is lower than the heights of the inner side surface 102 and outer side surface 101 of the ring die body 1.
[0059] Preferably, in actual use, a feeding trough is arranged above the ring die body 1, and the discharging width of the feeding trough is equal to the material receiving range of the mold cavity 105. The material discharged from the molten material container enters the trough and is dispersed and evenly enters the mold cavity 105.
[0060] The casting ring die disclosed in this embodiment can achieve rotary casting through its annular structure. That is, in industrial production, the die body 1 of the ring die is kept in a rotating state, and the die cavity 105 of the die body 1 is cast from above. The continuous casting can be realized by the rotation of the die body 1. The casting rate and the rotation rate are reasonably set to achieve the cooling and demoulding of the product and the cooling of the die before one full rotation is completed, and then the continuous cyclic casting can be realized to maintain continuous production. In this way, the requirement for the space of the production workshop is greatly reduced, and the processes such as the manual placement and demoulding of the die are also avoided. The casting container also remains in a fixed position without the need to bear movement, so as to improve the production efficiency and the production safety.
[0061] When it is necessary to control the casting amount in each die cavity 105, the die body 1 of the ring die can be inclined. When the casting amount in the current die cavity 105 reaches the maximum value, it will overflow and enter the next die cavity 105, so as to accurately ensure the amount of molten material in each die cavity 105. The molten material container is always kept open for continuous casting, and the control of the casting amount can be achieved without the need for opening and closing control. The control structure is simple but reliable.
[0062] Preferably, the die body 1 in this embodiment is made of metal material. By reasonably controlling the casting speed, the rotation speed and the combined cooling, the accommodation and cooling forming of the high-temperature molten material can be realized.
[0063] In this embodiment, the die cavity 105 is used to accommodate the molten material and serve as the space for its cooling and forming. In order to facilitate demoulding after solidification, the structure of the die cavity 105 can be constructed in various forms, which is not uniquely limited. In this embodiment, the structure of the die cavity 105 is optimized and one feasible option is adopted: the diameter of the die cavity 105 gradually increases from the cavity bottom to the cavity opening, and the inner walls of the die cavity 105 are designed with slopes on all four sides. When such a scheme is adopted, when the molten material cools, it will shrink towards the core, reducing the locking force. At the same time, the tapered opening formed by the inclined surface is consistent with the discharging direction, and the demoulding force is small. After the molten material cools and forms, it fits with the inner wall surface of the die cavity 105 surface to surface. The formed product 2 can be completely separated from the surrounding die cavities 105 by moving upward from the bottom, improving the convenience of demoulding.
[0064] Preferably, the die cavity 105 in this embodiment is constructed as a quadrilateral structure, and in some schemes, it can also be constructed as other polygonal or circular structures.
[0065] To meet the requirements of the actual production scale, the layout of the mold cavities 105 can be optimized, which is not uniquely defined. In this embodiment, an optimization is carried out and one of the feasible options is adopted: the mold cavities 105 are provided with several layers and are arranged successively outward along the circumference of the ring die body 1 to form an annular distribution. When such a scheme is adopted, both the inner layer of the mold cavity and the outer layer of the mold cavity 105 can achieve casting and cooling forming. When larger-scale casting production is required, the width of the ring die body 1 can be increased and more layers of mold cavities 105 can be set. When casting, the molten material is synchronously cast into the multi-layer mold cavities 105, and then synchronous cooling forming and synchronous demolding can be carried out, thereby improving the production efficiency.
[0066] When distributing the mold cavities 105 of different rings, an optimized setting can also be carried out. One of the feasible options proposed in this embodiment is: the corresponding mold cavities 105 on adjacent rings are located on the same radial line. When such a scheme is adopted, the volumes of adjacent mold cavities 105 are the same, and the casting amount can be synchronously controlled during casting, which is convenient for simplifying the casting control process.
[0067] In some other embodiments, the mold cavities 105 of different rings can also be arranged in a staggered manner. Then, during casting, staggered casting is carried out, and during demolding, staggered demolding is carried out. It is necessary to preset the time interval for cooling forming synchronously.
[0068] During demolding, in this embodiment, automatic demolding is realized by the way of jacking demolding. Specifically, an optimization is carried out and one of the following feasible options is adopted: a demolding hole 104 is provided at the bottom of the mold cavity 105, a demolding ejector rod 3 is arranged below the ring die body 1, and the demolding ejector rod 3 extends into the mold cavity 105 from the demolding hole 104. An ejection assembly 7 for jacking the demolding ejector rod 3 is arranged on the support assembly 8. The product 2 ejected from the mold cavity 105 slides into the discharge table 10 and is subjected to subsequent processing. When such a scheme is adopted, multiple mold cavities 105 can be demolded synchronously, which improves the demolding efficiency and convenience, reduces the damage to the product 2, and improves the quality of the product 2.
[0069] Preferably, the demolding ejector rod 3 cooperatively arranged at the demolding hole 104 closes and cooperates with the demolding hole 104 during casting, and rises and pushes the cooled and formed product 2 out of the mold cavity 105 when demolding is required.
[0070] Preferably, in this embodiment, an inclined transition surface 106 is formed between the demolding hole 104 and the bottom of the mold cavity 105.
[0071] In this embodiment, the structure of the ring die body 1 is optimized and one of the feasible options is adopted: the width of the upper casting surface of the ring die body 1 is smaller than the width of the lower part of the ring die body 1, so that the outer side surface 101 of the ring die body 1 forms an inclined surface. When such a scheme is adopted, the inner side surface 102 and the outer side surface 101 of the ring die body 1 are higher than the height of the template 103 to prevent the molten material from overflowing. However, when the casting amount is too large and exceeds the accommodation limit of the mold cavity 105, the molten material overflows outward and can be guided along the outer inclined surface of the ring die body 1 into the safety buffer tank below, thereby reducing the damage caused by the overflow of the molten material and improving the safety of casting.
[0072] Preferably, in order to improve the continuous operation ability of the rotary casting equipment, this embodiment is optimized and one of the feasible options is adopted: a cooling component and a mold release agent spraying component 6 are further arranged on the outer side of the ring die body 1. The cooling component includes an air cooling component for cooling the ring die body 1 and the molten material before demolding, and a water cooling component for cooling the ring die body 1 after demolding; the mold release agent spraying component 6 is used to spray the mold cavity 105 after demolding to form an interface coating on the surface of the mold cavity 105, so that the molten material is easy to separate, and the mold surface is smooth and clean.
[0073] Preferably, the air cooling components are arranged at multiple intervals above and below the ring die body 1.
[0074] As Figure 4 shown, as the rotary casting structure provided in this embodiment, the second structure thereof includes:
[0075] A mold table 4 for setting the ring die body 1, and the mold table 4 rotates coaxially with the ring die body 1.
[0076] In this embodiment, the ring die body 1 is driven to rotate by the mold table 4. The structure of the mold table 4 can be constructed in various forms and is not uniquely limited. This embodiment is optimized and one of the feasible options is adopted: the mold table 4 includes an annular casting table 401. The upper part of the casting table 401 is connected to the ring die body 1 in a matching manner. A rotary ring 404 is arranged in a matching manner at the lower part of the casting table 401. The bottom surface of the rotary ring 404 is in rolling cooperation with the support wheel set 802, and the side surface of the rotary ring 404 is in abutting cooperation with the adjusting wheel set 801. When such a scheme is adopted, the ring die body 1 can also be connected above the casting table 401 through an annular frame 402, and components such as the demolding ejector rod 3 can be arranged in the space structure of the annular frame 402; the lower part of the casting table 401 can also be connected and cooperated with the support component 8 through the annular frame 402, and the annular frame 402 is used to arrange structures such as the rotary ring 404 and the drive pin of the drive component 5.
[0077] As Figure 6 shown, as the rotary casting structure provided in this embodiment, the third structure thereof includes:
[0078] A supporting assembly 8 for supporting the die table 4 and the ring die body 1 and performing rotation; the supporting assembly includes a supporting wheel set 802 for supporting the die table 4 from below, and an adjusting wheel set 801 for pushing from the side to adjust the rotation center of the die table 4.
[0079] Preferably, in order to better support and rotate the supporting assembly 8 and perform rotation adjustment, this embodiment is optimized and a structure of the adjusting wheel set 801 is adopted: the adjusting wheel set 801 includes a plurality of adjusting arms 801c arranged along the circumference and deflected in the radial direction. An adjusting wheel 801a for abutting against the rotating ring 404 is arranged on the adjusting arm 801c. The adjusting arm 801c cooperates with a push-pull adjusting member 801b and adjusts the deflection angle through the push-pull adjusting member 801b.

[0090] Embodiment 2
[0091] This embodiment provides a rotary casting forming method for cold-setting materials, including:
[0092] S01: Preheat the material to the molten state, receive it through the molten material container and move it above the ring die body.
[0093] S02: Rotate the ring die body and reach the initial casting speed, and start casting at this time. The molten material is released from the container and enters the mold cavity of the ring die body after homogenization treatment. After the ring die body rotates through a set angle, the ring die body and the molten material are cooled.
[0094] Preferably, in this embodiment, a material leveling hopper is provided to receive the molten material lowered by the container, homogenize the material, and then evenly cast it into multiple columns of mold cavities.
[0095] S03: Adjust the flow rate of the molten material and / or the rotation speed of the ring die body so that the molten material cast into the mold cavity reaches a set amount. At the same time, the molten material cools and solidifies into a product when the ring die body rotates to a set angle.
[0096] S04: Demold the product that has cooled and solidified from below the ring die body, and the demolded product enters subsequent conveying and processing.
[0097] S05: After the ring die body is demolded, it continues to rotate and cools the demolded mold cavity, and sprays a mold release agent. When it rotates below the material container, casting is performed again.
[0098] The molten material in this embodiment is a high-temperature substance, and a large amount of heat is released outward during its cooling and solidification process. In order to reduce heat loss and recycle the heat, optimization is carried out here and one feasible option is proposed: after the ring die body is cast with the material, it rotates past the heat recovery component. The heat released during the cold solidification process of the molten material is exchanged through air flow, and the heated hot air material passes through the heat recovery component to reuse the heat. When adopting such a scheme, the heat recovery component includes a cooling air nozzle and a heat collecting hood. The heat collecting hood transports the heat exchange air to a set position through a duct, and the hot air can be transported to the furnace as auxiliary heat for preheating the material. The above are the implementation manners listed in this embodiment, but this embodiment is not limited to the above optional implementation manners. Those skilled in the art can obtain many other implementation manners by arbitrarily combining the above manners. Anyone can obtain various other forms of implementation manners under the inspiration of this embodiment. The above specific implementation manners should not be understood as limiting the protection scope of this embodiment, and the protection scope of this embodiment should be defined by the claims.
