Description

Technical Field

[0001] The invention relates to the technical field of teapot manufacturing, and in particular to a titanium teapot manufacturing device. Background Art

[0002] The lightweight and durable characteristics of titanium teapots make them easier to carry and use. At the same time, they are not easy to break and can remain in good condition for a long time. Secondly, titanium teapots have excellent corrosion resistance and are not corroded by acids, alkalis and other substances in tea, ensuring the purity and health of the tea. In addition, the good thermal conductivity of titanium allows the teapot to quickly transfer heat, ensuring that the brewed tea always maintains a suitable temperature; in summary, the functional advantages of titanium teapots compared to other teapots include lightness, durability, corrosion resistance, and good thermal insulation performance.

[0003] Chinese Patent Publication No.: CN116441524A discloses a casting device for the preparation of zinc-copper-titanium alloy, including an insulation box, an extrusion assembly is arranged inside the insulation box, a vibration assembly is fixedly connected to the bottom of the insulation box, a casting pipe is fixedly connected to one side of the insulation box, a feed pipe is fixedly connected to the top of the insulation box, and the extrusion assembly includes a high-temperature resistant extrusion plate, and the high-temperature resistant extrusion plate is slidably connected in the insulation box. In the present invention, by setting a vibration assembly, the motor drives the driven wheel to rotate through the driving wheel, the driven wheel drives the cam to rotate through the first connecting shaft, and the cam cooperates with the spring to realize the reciprocating motion of the slide bar, so that the slide bar can drive the knocking plate to reciprocate and vibrate the insulation box; it can be seen that the casting device for the preparation of zinc-copper-titanium alloy has the following problems: the casting process is not distinguished according to the morphological differences of the casting molds, and the liquid shrinkage during the casting process is easily irregular due to the difference in the molds, which affects the final cast product. Summary of the invention

[0004] To this end, the present invention provides a titanium teapot manufacturing device to overcome the problem in the prior art that the casting process is not differentiated according to the morphological differences of the casting molds, and the mold differences may lead to irregular liquid shrinkage during the casting process, affecting the final cast product.

[0005] To achieve the above object, the present invention provides a titanium teapot manufacturing device, comprising:

[0006] A manufacturing module, including a casting rod capable of controlling the casting speed and a casting mold;

[0007] An information acquisition module, including a plurality of scanning unit groups for acquiring point cloud data on the surface of a casting mold and a surface point cloud data on a teapot sample, and a thermal imaging device for acquiring a thermal imaging image of titanium liquid during the casting process of the teapot in real time;

[0008] A model building module, which is connected to the information acquisition module, and is used to build a three-dimensional model of the casting mold and obtain the casting capacity according to the surface point cloud data of the casting mold, and to build a three-dimensional model of the teapot sample according to the surface point cloud data of the teapot sample;

[0009] A manufacturing classification module, which is connected to the model building module, is used to determine the characterization parameters of the special-shaped casting according to the average curvature of the edge contour of the section of the three-dimensional model of the casting mold and the average plane curvature of the surface feature area of ​​the three-dimensional model to determine the casting shape category;

[0010] A classification manufacturing analysis module, which is respectively connected to the manufacturing module, the information collection module, the model building module and the manufacturing classification module, and is used to control the manufacturing module action according to the casting capacity obtained by the information collection module and the casting form category determined by the manufacturing classification module, including:

[0011] Casting is performed using a preset conventional casting speed, and casting stability characterization parameters are determined based on a thermal imaging image of the titanium liquid during the casting process of the teapot to determine whether the preset conventional casting speed needs to be reduced;

[0012] Alternatively, a preset special-shaped casting speed is used for casting, and whether the preset special-shaped casting speed needs to be reduced is determined according to the bubble area on the surface of the teapot sample after casting, and the setting position of the cold iron is determined according to the three-dimensional model of the teapot sample after cooling.

[0013] Furthermore, the manufacturing classification module obtains the average curvature of the cut surface edge by:

[0014] Constructing a first section and a second section perpendicular to the bottom surface of the three-dimensional model of the casting mold and passing through the center of the bottom surface, and obtaining average curvatures of the edges of the corresponding sections of the first section and the second section;

[0015] The first section is perpendicular to the second section, and the first section includes a complete water outlet of the teapot.

[0016] Furthermore, the manufacturing classification module determines the average curvature of the surface feature area of ​​the three-dimensional model including:

[0017] Determine a surface feature area of ​​the three-dimensional model surface, wherein the surface feature area includes a surface concave area and a surface convex area;

[0018] determining an average planar curvature of each of the surface feature regions;

[0019] Wherein, the average plane curvature of the surface feature area must be greater than a predetermined plane curvature threshold.

[0020] Furthermore, the manufacturing classification module calculates the characteristic parameters of the special-shaped casting according to formula (1),

[0021]

[0022] In formula (1), E represents the characteristic parameter of special-shaped casting, R represents the average curvature, R0 represents the standard average curvature, P represents the average plane curvature, P0 represents the standard plane curvature, g1 represents the two-dimensional special-shaped weight, and g2 represents the three-dimensional special-shaped weight.

[0023] Furthermore, the manufacturing classification module determines the casting morphology category according to the special-shaped casting characterization parameter, and the casting morphology category includes a conventional casting morphology category and a special-shaped casting morphology category.

[0024] Wherein, if the special-shaped casting characterization parameter is greater than the preset special-shaped casting parameter, the casting morphology category is the special-shaped casting morphology category;

[0025] If the special-shaped casting characterization parameter is less than or equal to the preset special-shaped casting parameter, the casting shape category is a conventional casting shape category.

[0026] Furthermore, the classification manufacturing analysis module selects a corresponding teapot casting strategy according to the casting capacity information obtained by the information collection module and the casting form category determined by the manufacturing classification module.

[0027] If the preset casting conditions are met, casting is performed using a preset conventional casting speed, and casting stability characterization parameters are determined based on the thermal imaging image of the titanium liquid during the casting process of the teapot to determine whether the preset conventional casting speed needs to be reduced;

[0028] If the preset casting conditions are not met, the preset special-shaped casting speed is used for casting, and whether the preset special-shaped casting speed needs to be reduced is determined according to the bubble area on the surface of the teapot sample after casting, and the setting position of the cold iron is determined according to the three-dimensional model of the teapot sample after cooling;

[0029] Among them, the preset casting condition is that the casting shape category is a conventional casting shape category and the casting capacity is greater than or equal to the preset capacity.

[0030] Furthermore, the classification manufacturing analysis module determines the casting stability characterization parameter according to formula (2):

[0031]

[0032] In formula (2), G is the casting stability characterization parameter, m is the total number of key points in the thermal imaging image, Hj is the temperature of the jth key point in the current casting process, T0 is the average temperature of the key points in the casting process, and j is an integer greater than 0.

[0033] Furthermore, judging whether it is necessary to reduce the preset conventional casting speed according to the casting stability characterization parameter,

[0034] If the casting stability characterization parameter is greater than or equal to the preset characterization parameter, it is determined that the preset conventional casting speed needs to be reduced;

[0035] If the casting stability characteristic parameter is less than the preset characteristic parameter, it is determined that there is no need to reduce the preset conventional casting speed.

[0036] Furthermore, the classification manufacturing module determines whether it is necessary to reduce the preset special-shaped casting speed according to the bubble area on the surface of the teapot sample within a certain period of time after the teapot is cast.

[0037] If the bubble area on the surface of the teapot sample is larger than the standard bubble area, it is determined that the preset special-shaped casting speed needs to be reduced;

[0038] If the bubble area on the surface of the teapot sample is less than or equal to the standard bubble area, it is determined that there is no need to reduce the preset special-shaped casting speed.

[0039] Furthermore, the classification manufacturing analysis module determines the location of the cold iron according to the surface characteristics of the cooled teapot sample.

[0040] The classification manufacturing analysis module obtains the three-dimensional model of the teapot sample;

[0041] The classification manufacturing analysis module compares the three-dimensional model of the teapot sample with the three-dimensional model of the casting mold, determines the surface feature areas where the three-dimensional model of the teapot sample is different from the three-dimensional model of the casting mold, and records them as abnormal feature areas;

[0042] The cold iron is disposed at each of the abnormal characteristic regions.

[0043] Compared with the prior art, the beneficial effects of the present invention lie in that the information acquisition module utilizes point cloud data and audio information to obtain key data on the casting mold surface and the casting process; the manufacturing classification module utilizes a three-dimensional model and curvature analysis to determine the casting morphology category, providing a basis for subsequent operations; the classification manufacturing analysis module selects a suitable casting strategy according to the casting capacity and the casting morphology category, and makes real-time adjustments according to the casting stability and bubble content. The present invention distinguishes the casting process according to the differences in casting molds, eliminates the irregular interference of liquid shrinkage in the casting process caused by mold differences, and improves the accuracy and stability of the casting process.

[0044] Furthermore, in the present invention, obtaining two cross-sections can effectively avoid the situation where the calculation result of a single cross-section is not representative of the shape of the mold due to the irregular shape of the casting mold, thereby affecting the shape judgment of the casting mold, resulting in the final casting method selection error, and affecting the final teapot casting result.

[0045] Furthermore, in the present invention, the larger the parameter characterizing the special-shaped casting, the more concave or convex surfaces appear on the surface of the casting mold, and the more irregular areas are contained in the area with more surface special-shaped areas. During the casting process, the irregular areas may easily cause the liquid flow path to become complicated when casting the liquid, and cause the uncooled titanium liquid after casting to have different cooling processes at different positions during the cooling process due to uneven heat dissipation, resulting in a large difference between the shape of the teapot and the model due to the compensation of the titanium cooling process. Therefore, classifying the model and selecting the corresponding method for casting can ensure the quality of the final teapot.

[0046] Furthermore, the large temperature difference of the mold during the cooling process indicates that the flow rate in the current casting process is too fast. The excessive flow rate of the titanium liquid during the casting process may cause the liquid added first to not shrink sufficiently, and not be compensated after the shrinkage is completed, thereby affecting the final quality of the casting. By reducing the casting speed, the above problems can be effectively avoided and the final casting quality can be guaranteed.

[0047] Furthermore, in the present invention, by adjusting the casting speed by the bubble area on the surface of the cast teapot sample, bubbles generated or drawn into the mold by the excessively fast casting speed of the titanium liquid can be reduced, thereby reducing the influence of the presence of bubbles on the casting results.

[0048] Furthermore, in the present invention, by comparing the three-dimensional model of the teapot sample with the three-dimensional model of the casting mold, the abnormal characteristic area that needs to be cooled can be accurately identified. The provision of chills in the abnormal characteristic area can promote sequential solidification, reduce casting defects such as shrinkage cavities and shrinkage, and improve the integrity and reliability of the casting. Through targeted cooling, complex castings can be processed more finely. The use of chills can better control the cooling process and the shape of the casting, while reducing the non-uniformity in the cooling process, which helps to improve the surface quality and dimensional accuracy of the casting.

[0057] See also Figure 1 As shown, it is a structural schematic diagram of a titanium teapot manufacturing device according to an embodiment of the present invention; the present invention provides a titanium teapot manufacturing device, comprising:

[0058] A manufacturing module, including a casting rod capable of controlling the casting speed and a casting mold;

[0059] An information acquisition module, including a plurality of scanning unit groups for acquiring point cloud data on the surface of a casting mold and a surface point cloud data on a teapot sample, and a thermal imaging device for acquiring a thermal imaging image of titanium liquid during the casting process of the teapot in real time;

[0060] A model building module, which is connected to the information acquisition module, and is used to build a three-dimensional model of the casting mold and obtain the casting capacity according to the surface point cloud data of the casting mold, and to build a three-dimensional model of the teapot sample according to the surface point cloud data of the teapot sample;

[0061] A manufacturing classification module, which is connected to the model building module, is used to determine the characterization parameters of the special-shaped casting according to the average curvature of the edge contour of the section of the three-dimensional model of the casting mold and the average plane curvature of the surface feature area of ​​the three-dimensional model to determine the casting shape category;

[0062] A classification manufacturing analysis module is respectively connected to the manufacturing module, the information collection module, the model building module and the manufacturing classification module, and is used to control the operation of the manufacturing module according to the casting capacity obtained by the information collection module and the casting form category determined by the manufacturing classification module.

[0063] The manufacturing module comprises performing casting at a preset conventional casting speed, and determining casting stability characterization parameters according to a thermal imaging image of the titanium liquid during the casting process of the teapot to determine whether it is necessary to reduce the preset conventional casting speed;

[0064] Alternatively, a preset special-shaped casting speed is used for casting, and whether the preset special-shaped casting speed needs to be reduced is determined according to the bubble area on the surface of the teapot sample after casting, and the setting position of the cold iron is determined according to the three-dimensional model of the teapot sample after cooling.

[0065] In this embodiment, the manufacturing module is any casting device with adjustable casting speed in the existing titanium casting technology, which is not specifically limited here.

[0066] The scanning unit group includes several scanning instruments, which can collect the surface point cloud data of the casting mold and the surface point cloud data of the teapot sample through laser scanning. This is the existing technology and will not be described in detail here.

[0067] The thermal imaging device for acquiring the thermal imaging image of the titanium liquid during the casting process of the teapot in real time can be any one of the existing audio sensors, such as a thermal imaging camera, an infrared thermal imager, a thermal vision device, etc., which is not specifically limited here.

[0068] In implementation, the present invention does not limit the specific structures of the manufacturing classification module, the classification manufacturing analysis module and the model building module, which can be composed of logical components, including field programmable processors, computers and microprocessors in computers.

[0069] The information acquisition module uses point cloud data and audio information to obtain key data on the casting mold surface and the casting process. The manufacturing classification module uses a three-dimensional model and curvature analysis to determine the casting morphology category, providing a basis for subsequent operations. The classification manufacturing analysis module selects a suitable casting strategy based on the casting capacity and casting morphology category, and makes real-time adjustments based on the casting stability and bubble content. The present invention distinguishes the casting process according to the differences in casting molds, eliminates the irregular interference of liquid shrinkage in the casting process caused by mold differences, and improves the accuracy and stability of the casting process.

[0070] Specifically, the manufacturing classification module obtains the average curvature of the edge of the cut surface by:

[0071] Constructing a first section and a second section perpendicular to the bottom surface of the three-dimensional model of the casting mold and passing through the center of the bottom surface, and obtaining average curvatures of the edges of the corresponding sections of the first section and the second section;

[0072] The first section is perpendicular to the second section, and the first section includes a complete water outlet of the teapot.

[0073] In implementation, the first section and the second section are both perpendicular to the bottom surface of the mold, and the first section is a section passing through the center of the water outlet. The section used for detection and analysis includes the spout part of the mold, which can make the overall shape judgment of the mold more accurate.

[0074] The average curvature is determined according to the edge of the cut surface corresponding to the bottle body of the casting mold, and the average curvature is the average of the average curvatures of the four cut surface edges;

[0075] The average curvature of the edge is determined from the mean of the curvatures of the concave edge or the convex edge.

[0076] In the present invention, obtaining two cross-sections can effectively avoid the situation where the calculation result of a single cross-section is not representative of the shape of the mold due to the irregular shape of the casting mold, thereby affecting the shape judgment of the casting mold, resulting in the final casting method selection error, and affecting the final teapot casting result.

[0077] Specifically, the manufacturing classification module determines the average curvature of the surface feature area of ​​the three-dimensional model by:

[0078] Determine a surface feature area of ​​the three-dimensional model surface, wherein the surface feature area includes a surface concave area and a surface convex area;

[0079] determining an average planar curvature of each of the surface feature regions;

[0080] Wherein, the average plane curvature of the surface feature area must be greater than a predetermined plane curvature threshold.

[0081] In this embodiment, the surface concave areas and surface convex areas are determined according to the three-dimensional model, and point cloud segmentation can be performed according to the point cloud data. A point cloud segmentation algorithm based on concavity and convexity can be used to analyze the local structural features of the point cloud and divide the point cloud into different areas. The surface convex areas and surface concave areas of the three-dimensional model surface can be identified. This is a prior art and will not be elaborated here.

[0082] In implementation, the average plane curvatures of the surface concave area and the surface convex area are both positive values, indicating the degree of curvature of the surface feature area;

[0083] The predetermined plane curvature threshold is selected in the interval [1 / 3r, 1 / 2r], where r is the radius of the sphere corresponding to the center point of the surface feature area.

[0084] See also Figure 2 As shown, it is a logic diagram for determining the casting morphology category in an embodiment of the present invention. The manufacturing classification module calculates the characteristic parameters of the special-shaped casting according to formula (1).

[0085]

[0086] In formula (1), E represents the characteristic parameter of special-shaped casting, R represents the average curvature, R0 represents the standard average curvature, P represents the average plane curvature, P0 represents the standard plane curvature, g1 represents the two-dimensional special-shaped weight, and g2 represents the three-dimensional special-shaped weight.

[0087] In practice, g1+g2=1, generally, g2>g1, in this embodiment, g2=0.65, g1=0.35.

[0088] The standard average curvature is the average curvature of the casting mold used for qualified teapots after casting in the historical casting records without adjusting the casting process. Similarly, the standard plane curvature is the average plane curvature of the casting mold used for qualified teapots after casting in the historical casting records without adjusting the casting process.

[0089] Specifically, the manufacturing classification module determines the casting morphology category according to the special-shaped casting characterization parameter, and the casting morphology category includes a conventional casting morphology category and a special-shaped casting morphology category.

[0090] Wherein, if the special-shaped casting characterization parameter is greater than the preset special-shaped casting parameter, the casting morphology category is the special-shaped casting morphology category;

[0091] If the special-shaped casting characterization parameter is less than or equal to the preset special-shaped casting parameter, the casting shape category is a conventional casting shape category.

[0092] In practice, the preset special-shaped casting parameters are selected in the range [1.1,1.3]. Generally, the larger the casting capacity, the larger the preset special-shaped casting parameters.

[0093] In the present invention, the larger the parameter characterizing the special-shaped casting is, the more concave or convex surfaces appear on the surface of the casting mold, and the more irregular areas are contained in the area with more surface special-shaped areas. In the casting process, the irregular areas may easily cause the liquid flow path to become complicated when casting the liquid, and cause the uncooled titanium liquid after casting to have different cooling processes at different positions during the cooling process due to uneven heat dissipation, so that the compensation of the titanium cooling process leads to a large difference between the shape of the teapot and the model. Therefore, classifying the model and selecting the corresponding method for casting can ensure the quality of the final teapot.

[0094] Specifically, the classification manufacturing analysis module selects a corresponding teapot casting strategy according to the casting capacity information obtained by the information collection module and the casting form category determined by the manufacturing classification module.

[0095] If the preset casting conditions are met, casting is performed using a preset conventional casting speed, and casting stability characterization parameters are determined based on the thermal imaging image of the titanium liquid during the casting process of the teapot to determine whether the preset conventional casting speed needs to be reduced;

[0096] If the preset casting conditions are not met, the preset special-shaped casting speed is used for casting, and whether the preset special-shaped casting speed needs to be reduced is determined according to the bubble area on the surface of the teapot sample after casting, and the setting position of the cold iron is determined according to the three-dimensional model of the teapot sample after cooling;

[0097] Among them, the preset casting condition is that the casting shape category is a conventional casting shape category and the casting capacity is greater than or equal to the preset capacity.

[0098] In practice, the preset capacity is set at 1.5 liters.

[0099] It is understandable that at the same casting speed, a large-volume casting mold usually takes longer time in the casting process than a small-volume casting mold. During the casting process, the first cast part of the large-volume mold will begin to cool and shrink first, requiring the later added titanium liquid to compensate. Therefore, reducing the casting speed can reduce the impact of the shrinkage of the first cooled titanium liquid on the final teapot.

[0100] In the present invention, the different sound temperature change rates of the casting mold during the casting process are different according to the different sizes of the molds, and the corresponding casting method is selected in combination with the casting shape category. While avoiding the problem of heat dissipation and shrinkage of titanium liquid during the casting process of the special-shaped mold affecting the final casting quality, the detection method of the casting process is simplified, the accuracy of the detection is improved, and a better basis is provided for the subsequent adjustment of the casting speed, thereby further improving the casting quality.

[0101] See also Figure 3 As shown, it is a logic diagram for judging whether it is necessary to reduce the preset conventional casting speed according to an embodiment of the present invention. The classification manufacturing analysis module determines the casting stability characterization parameter according to formula (2):

[0102]

[0103] In formula (2), G is the casting stability characterization parameter, m is the total number of key points in the thermal imaging image, Hj is the temperature of the jth key point in the current casting process, T0 is the average temperature of the key points in the casting process, and j is an integer greater than 0.

[0104] In implementation, the number of key points is not less than 100 and is evenly arranged in the thermal imaging image, and the temperature of the key points can be directly read from the thermal imaging image acquired by the thermal imaging device.

[0105] It can be understood that when casting the casting mold, the more uniform the heat dissipation of the titanium liquid, the global shrinkage occurs, and the more regular the shape of the final titanium teapot is.

[0106] Specifically, judging whether it is necessary to reduce the preset conventional casting speed according to the casting stability characterization parameter,

[0107] If the casting stability characterization parameter is greater than or equal to the preset characterization parameter, it is determined that the preset conventional casting speed needs to be reduced;

[0108] If the casting stability characteristic parameter is less than the preset characteristic parameter, it is determined that there is no need to reduce the preset conventional casting speed.

[0109] In implementation, the preset characterization parameter is selected within the interval [0.1, 0.2].

[0110] In this embodiment, the reduction amount of the preset conventional casting speed is △v1=(G1-G0) / G0×v1, G1 is the casting stability characterization parameter, G0 is the preset characterization parameter, and v1 is the preset conventional casting speed.

[0111] In the present invention, a large temperature difference in the mold during the cooling process indicates that the flow rate in the current casting process is too fast. A too high flow rate of the titanium liquid during the casting process may cause the liquid added first to not shrink sufficiently, and not be compensated after the shrinkage is completed, thereby affecting the final quality of the casting. By reducing the casting speed, the above problems can be effectively avoided and the final casting quality can be guaranteed.

[0112] Specifically, the classification manufacturing module determines whether it is necessary to reduce the preset special-shaped casting speed according to the bubble area on the surface of the teapot sample within a certain period of time after the teapot is cast.

[0113] If the bubble area on the surface of the teapot sample is larger than the standard bubble area, it is determined that the preset special-shaped casting speed needs to be reduced;

[0114] If the bubble area on the surface of the teapot sample is less than or equal to the standard bubble area, it is determined that there is no need to reduce the preset special-shaped casting speed.

[0115] In practice, the standard bubble area is defined as 2% of the surface area of ​​the teapot mold, that is, the area of ​​the bubble on the surface of the teapot sample does not exceed 2% of the surface area of ​​the teapot.

[0116] It is understandable that the bubble content can be achieved through any machine vision technology, such as measuring and calculating the area of ​​the bubble through optical equipment combined with image processing technology. This is a prior art and is not specifically limited here.

[0117] In the present invention, the casting speed is adjusted by the bubble area on the surface of the short-time pot sample, so as to reduce the bubbles generated or drawn into the mold due to the excessively fast casting speed of the titanium liquid during the casting process, thereby reducing the influence of the existence of bubbles on the casting results.

[0118] See also Figure 4 As shown, it is a logic diagram for determining the setting position of the cold iron in the present invention. The classification manufacturing analysis module determines the setting position of the cold iron according to the surface characteristics of the teapot sample after cooling.

[0119] The classification manufacturing analysis module obtains the three-dimensional model of the teapot sample;

[0120] The classification manufacturing analysis module compares the three-dimensional model of the teapot sample with the three-dimensional model of the casting mold, determines the surface feature areas where the three-dimensional model of the teapot sample is different from the three-dimensional model of the casting mold, and records them as abnormal feature areas;

[0121] The cold iron is disposed at each of the abnormal characteristic regions.

[0122] Chill is a high thermal conductivity material, usually placed in certain key areas of the mold to accelerate the cooling rate of these areas and change the solidification order of the casting; the material of the chill should have high thermal conductivity and high strength, preferably metal chill (cast iron or steel) or non-metal chill (such as sand chill).

[0123] Chills can promote sequential solidification of castings, that is, solidification starts from the part far away from the hot zone and gradually advances to the hot zone. By controlling the solidification sequence, chills help reduce shrinkage cavities and shrinkage defects inside castings.

[0124] In this embodiment, the chill is set in the abnormal feature area to help the irregular surface area to cool and shrink, while allowing the subsequently added liquid to provide timely compensation so that the resulting teapot shape is the same as the mold shape.

[0125] In the present invention, by comparing the three-dimensional model of the teapot sample with the three-dimensional model of the casting mold, the abnormal characteristic area that needs to be cooled can be accurately identified. Setting a chill in the abnormal characteristic area can promote sequential solidification, reduce casting defects such as shrinkage cavities and shrinkage, and improve the integrity and reliability of the casting. Through targeted cooling, complex castings can be processed more finely. The use of chills can better control the cooling process and the shape of the casting, while reducing the non-uniformity in the cooling process, which helps to improve the surface quality and dimensional accuracy of the casting.

[0126] In this embodiment, there is a riser part in the setting of the mold, which serves as an additional metal storage reservoir during the cooling and solidification of the casting to compensate for the shrinkage of the casting. However, the riser part is not considered in the process of constructing the three-dimensional model to avoid affecting the judgment result of the casting morphology category.
