Description

Technical Field

[0001] This application relates to the field of die casting technology, and in particular to a die casting control method, system, electronic device and storage medium. Background Technology

[0002] When die-casting aluminum or zinc alloy products, the molten aluminum or zinc alloy needs to be poured into the die-casting machine's melting cup. Traditionally, this is done manually, which is difficult to control the amount of molten metal and is prone to accidents. To reduce the labor intensity of workers and save on labor costs, a molten metal pouring machine is used to replace manual pouring. The working principle of the molten metal pouring machine is as follows: The machine is set with a set angle for the ladle. The ladle is submerged into the molten aluminum alloy at the set angle and then slowly lifted out. Excess molten aluminum alloy flows out of the ladle through the tilted angle, and the remaining molten aluminum alloy in the ladle is the required weight of molten metal for the die-cast product.

[0003] In related technologies, operators blindly set the angle of the ladle to scoop the soup, based on experience or guesswork, according to the size of the ladle and the required liquid weight of the die-cast product. This method results in low accuracy in the weight of the liquid scooped by the ladle, requiring manual verification of the final scooping angle, which greatly increases labor costs. Summary of the Invention

[0004] In view of this, this application provides a die-casting control method, system, electronic device and storage medium, which can realize the automatic confirmation of the tilt angle of the ladle, reduce labor costs and improve the accuracy of the weight of the molten metal scooped by the ladle.

[0005] This application provides a die-casting control method applied to a die-casting control system. The die-casting control system includes a ladle feeder. The ladle feeder includes a transmission component and a ladle pulverizedly connected to the transmission component. The transmission component moves to rotate the ladle, causing it to be at different tilt angles. The method includes: acquiring first simulation data and second simulation data after performing motion simulation on the die-casting control system. The first simulation data includes the movement distance of the transmission component and the tilt angle of the ladle corresponding to the movement distance. The second simulation data includes the tilt angle and the weight of the molten metal scooped by the ladle corresponding to the tilt angle. Based on the... The first simulation data is used to determine a first relationship curve between the movement distance and the tilt angle; the second simulation data is used to determine a second relationship curve between the tilt angle and the weight of the molten metal; the first and second relationship curves are used to obtain a third relationship curve between the movement distance and the weight of the molten metal; the target weight of the molten metal required for the die-cast product is determined; the target movement distance of the transmission component corresponding to the target weight of the molten metal is obtained according to the third relationship curve; the movement of the transmission component is controlled according to the target movement distance to rotate the ladle to the target tilt angle; and the ladle is controlled to scoop up the molten metal at the target tilt angle.

[0006] Compared with related technologies, the embodiments of this application have at least the following advantages: By performing motion simulation on the die-casting control system, a large amount of first and second simulation data can be obtained. Since the first simulation data includes the movement distance of the transmission component and the tilt angle of the ladle corresponding to the movement distance, a first relationship curve between the movement distance and the tilt angle can be obtained from the first simulation data; similarly, a second relationship curve between the tilt angle and the weight of the molten metal can be obtained from the second simulation data. Furthermore, since the first relationship curve represents the correspondence between the tilt angle and the movement distance, and the second relationship curve represents the correspondence between the tilt angle and the weight of the molten metal, a third relationship curve between the movement distance and the weight of the molten metal can be obtained from the first and second relationship curves. Thus, after determining the target weight of the molten metal required for the die-cast product, the target movement distance of the transmission component corresponding to the target weight of the molten metal can be obtained based on the third relationship curve. Then, by controlling the movement of the transmission component through the target movement distance, the tilt angle of the ladle is automatically confirmed, ensuring that the weight of the molten metal scooped by the ladle at the target tilt angle is equal to the target weight of the molten metal, thereby improving the accuracy of the weight of the molten metal scooped by the ladle. In addition, the entire process of confirming the tilt angle of the ladle and scooping the molten metal does not require manual intervention, reducing labor costs.

[0007] In some possible implementations, the die-casting control system further includes a die-casting machine, the die-casting machine including a pressure chamber, a punch disposed within the pressure chamber, and a mold cavity communicating with the pressure chamber; the pressure chamber receives molten metal injected by the ladle, the punch moves within the pressure chamber to form the die-cast product within the mold cavity, the die-cast product including a stalk abutting against the punch; the method further includes: acquiring third simulation data after performing motion simulation on the die-casting control system, wherein the third simulation data includes the weight of the molten metal and the punch position within the pressure chamber; determining the stalk thickness based on the punch position; and determining the stalk thickness based on the third simulation data and the... The process includes: determining a fourth relationship curve between the molten metal weight and the stalk thickness; obtaining a fifth relationship curve between the movement distance and the stalk thickness based on the third and fourth relationship curves; after the molten metal scooped by the ladle is injected into the die-casting machine, the process further includes: determining the final punch position of the punch in the pressure chamber, and determining the actual stalk thickness based on the final punch position; obtaining the target stalk thickness corresponding to the target movement distance based on the fifth relationship curve; comparing the actual stalk thickness and the target stalk thickness, and detecting whether the actual molten metal weight scooped by the ladle meets the preset die-casting requirements based on the comparison result.

[0008] In some possible implementations, the step of detecting whether the actual weight of the molten metal scooped by the ladle meets the preset die-casting requirements based on the comparison result includes: if the comparison result shows that the actual stalk thickness is not equal to the target stalk thickness, detecting that the actual weight of the molten metal does not meet the preset die-casting requirements; and if the comparison result shows that the actual stalk thickness is equal to the target stalk thickness, detecting that the actual weight of the molten metal meets the preset die-casting requirements.

[0009] In some possible implementations, after detecting that the actual molten metal weight does not meet the preset die-casting requirements, the method further includes: calculating the thickness difference between the target spool thickness and the actual spool thickness; obtaining a molten metal weight compensation value corresponding to the thickness difference based on the fourth relationship curve; adding the molten metal weight compensation value and the target molten metal weight to obtain a molten metal weight sum; determining a corrected tilt angle corresponding to the molten metal weight sum based on the second relationship curve; and controlling the ladle to scoop molten metal at the corrected tilt angle during the die-casting process of the next product to be die-cast.

[0010] In some possible implementations, the fourth relationship curve is a linear curve; determining the fourth relationship curve between the weight of the molten metal and the thickness of the stalk based on the third simulation data and the stalk thickness includes: establishing a Cartesian coordinate system; using the weight of the molten metal as the abscissa of the Cartesian coordinate system and the thickness of the stalk as the ordinate of the Cartesian coordinate system to obtain multiple sets of first coordinate points of the weight of the molten metal and the thickness of the stalk in the Cartesian coordinate system; and obtaining the fourth relationship curve based on the multiple sets of first coordinate points.

[0011] In some possible implementations, the first relationship curve is a linear curve; determining the first relationship curve between the motion distance and the tilt angle based on the first simulation data includes: establishing a Cartesian coordinate system; using the motion distance as the abscissa of the Cartesian coordinate system and the tilt angle as the ordinate of the Cartesian coordinate system to obtain multiple sets of second coordinate points of the first simulation data in the Cartesian coordinate system; and obtaining the first relationship curve based on the multiple sets of second coordinate points.

[0012] In some possible implementations, the second relationship curve is a linear curve; determining the second relationship curve between the tilt angle and the weight of the molten metal based on the second simulation data includes: establishing a Cartesian coordinate system; using the tilt angle as the abscissa of the Cartesian coordinate system and the weight of the molten metal as the ordinate of the Cartesian coordinate system to obtain multiple sets of third coordinate points of the second simulation data in the Cartesian coordinate system; and obtaining the second relationship curve based on the multiple sets of third coordinate points.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0031] Please refer to Figure 1 The above is a flowchart of a die-casting control method provided in an embodiment of this application. This embodiment is applied to a die-casting control system, which includes a soup feeder. The soup feeder includes a transmission component and a soup ladle that is connected to the transmission component. The movement of the transmission component drives the soup ladle to rotate, so that the soup ladle is at different tilt angles.

[0032] The die-casting control method in this embodiment includes the following steps:

[0033] Step 101: Obtain the first and second simulation data after performing motion simulation on the die-casting control system.

[0034] Specifically, the first simulation data includes the movement distance of the transmission component and the tilt angle of the ladle corresponding to the movement distance; the second simulation data includes the tilt angle of the ladle and the weight of the molten metal scooped up by the ladle corresponding to the tilt angle.

[0035] In some embodiments, the motion simulation process of the die-casting control system is as follows: The die-casting control system drives the transmission component to rotate, thereby placing the ladle at different tilt angles. That is, each movement distance of the transmission component corresponds to a tilt angle of the ladle.

[0036] Please refer to Figure 2 , Figure 2 This image illustrates application scenarios where a ladle is used to scoop up molten metal at different tilt angles. From... Figure 2As can be seen, the weight of the molten metal scooped up by the spoon varies depending on the spoon's tilt angle. In other words, each tilt angle of the spoon corresponds to a specific weight of molten metal scooped up.

[0037] It is understood that the motion simulation process of the die-casting control system also includes the die-casting process of the die-casting machine, which is described in detail in subsequent embodiments. To avoid repetition, it will not be repeated here.

[0038] Step 102: Determine the first relationship curve between the movement distance of the transmission component and the tilt angle of the ladle based on the first simulation data.

[0039] In some embodiments, the first relationship curve is a linear curve, and the method for determining the first relationship curve includes: establishing a Cartesian coordinate system; using the motion distance as the abscissa of the Cartesian coordinate system and the tilt angle as the ordinate of the Cartesian coordinate system to obtain multiple sets of second coordinate points of the first simulation data in the Cartesian coordinate system; and obtaining the first relationship curve based on the multiple sets of second coordinate points.

[0040] To facilitate understanding, the following example, using the first simulation data including the movement distance of 100 sets of transmission components and the tilt angle of the ladle, will specifically illustrate how the first relationship curve is obtained in this embodiment:

[0041] The movement distance of each set of transmission components and the tilt angle of the ladle corresponding to that movement distance are converted into second coordinate points, resulting in 100 sets of second coordinate points. Based on linear fitting, such as the least squares method, the first relationship curve corresponding to the 100 discrete second coordinate points is determined.

[0042] Step 103: Determine the second relationship curve between the tilt angle of the ladle and the weight of the molten metal based on the second simulation data.

[0043] In some embodiments, the second relationship curve is a linear curve, and the method for determining the second relationship curve includes: establishing a plane rectangular coordinate system; using the tilt angle as the abscissa of the plane rectangular coordinate system and the weight of the metal solution as the ordinate of the plane rectangular coordinate system to obtain multiple sets of third coordinate points of the second simulation data in the plane rectangular coordinate system; and obtaining the second relationship curve based on the multiple sets of third coordinate points.

[0044] It is understandable that the method for determining the second relationship curve is the same as that for determining the first relationship curve, and will not be repeated here to avoid repetition.

[0045] Step 104: Based on the first and second relationship curves, obtain the third relationship curve between the movement distance of the transmission component and the weight of the molten metal.

[0046] Specifically, since the first relationship curve represents the correspondence between the tilt angle and the movement distance, and the second relationship curve represents the correspondence between the tilt angle and the weight of the molten metal, a third relationship curve between the movement distance and the weight of the molten metal can be obtained through the first and second relationship curves.

[0047] Understandably, the third relationship curve is also a linear curve.

[0048] Step 105: Determine the target metal solution weight required for the product to be die-cast.

[0049] In some embodiments, the operator inputs the weight of the target molten metal via the die-casting control system.

[0050] In some embodiments, the die-casting control system pre-stores the weights of molten metal corresponding to different types of products to be die-cast. Operators can also select the type of product to be die-cast in the die-casting control system, and the die-casting control system determines the target molten metal weight corresponding to that type.

[0051] It is understood that this embodiment does not specifically limit the method for determining the weight of the target metal solution, and can be set according to actual needs.

[0052] Step 106: Obtain the target motion distance of the transmission component corresponding to the weight of the target metal solution based on the third relationship curve.

[0053] Specifically, since the third relationship curve characterizes the correspondence between the weight of the molten metal and the movement distance, the die-casting control system stores the third relationship curve in advance. Therefore, after the die-casting control system obtains the target weight of the molten metal, it can obtain the target movement distance corresponding to the target weight of the molten metal based on the third relationship curve.

[0054] Step 107: Control the movement of the transmission component according to the target movement distance so that the ladle rotates to the target tilt angle.

[0055] Specifically, the die-casting control system controls the movement of the transmission components to the target distance, and the ladle will rotate to the target tilt angle corresponding to the target movement distance. The weight of the molten metal scooped up by the ladle at the target tilt angle is equal to the weight of the target molten metal.

[0056] Step 108: Control the ladle to scoop the molten metal at the target tilt angle.

[0057] In some embodiments, the die-casting control system further includes a soup-feeding control device for operating the soup-feeding machine, which controls the movement of the soup-feeding machine so that a ladle scoops up the molten metal.

[0058] To facilitate understanding, the following will be combined with... Figure 3 and Figure 4This embodiment provides a detailed explanation of how the soup dispensing control device controls the ladle to scoop up the molten metal:

[0059] Please refer to Figure 3 , Figure 3 This is a schematic diagram of the structure of the soup dispenser provided in the embodiment of this application. The soup dispenser 10 includes a mounting component 11, a transmission component 12, and a soup ladle 13. The soup ladle 13 is rotatably connected to the mounting component 11, and the transmission component 12 is connected to the soup ladle 13. The connection between the transmission component 12 and the soup ladle 13 is spaced apart from the connection between the mounting component 11 and the soup ladle 13, so that the transmission component 12 can drive the soup ladle 13 to rotate relative to the mounting component 11 and scoop up the molten metal.

[0060] Specifically, Figure 4 The transmission component 12 shown drives the ladle 13 to rotate by moving in the vertical direction. The height of the transmission component 12 when it rises and falls determines the rotation angle of the ladle 13.

[0061] Please refer to Figure 4 This is an application scenario diagram of a ladle used in this application to scoop molten metal in a heat-preserving furnace. Figure 4 The heat preservation furnace 20 shown contains a metal solution 30.

[0062] like Figure 4 As shown in (a), the soup control device controls the movement of the soup dispenser 10 so that the soup ladle 13 is positioned above the heat preservation furnace 20.

[0063] like Figure 4 As shown in (b), the soup control device controls the transmission component 12 to move the target distance in the vertical direction, so that the soup ladle 13 rotates to the target tilt angle. Figure 3 As can be seen, when the transmission component 12 rises, the tilt angle of the ladle 13 decreases, and when the transmission component 12 falls, the tilt angle of the ladle 13 increases. Therefore, in this embodiment, the rise or fall of the transmission component 12 can be indicated by setting the positive or negative value of the movement distance. For example, when the movement distance is -5 cm, the soup control device controls the transmission component 12 to fall by 5 cm, and when the movement distance is 10 cm, the soup control device controls the transmission component 12 to rise by 10 cm.

[0064] like Figure 4 As shown in (c), the soup control device controls the soup dispenser 10 to move downward so that the soup ladle 13 is located inside the heat preservation furnace 20, and the molten metal 30 flows into the soup ladle 13.

[0065] like Figure 4 As shown in (d), after the ladle 13 has scooped up the metal solution 30, the soup control device controls the soup dispenser 10 to move upward so that the ladle 13 is once again above the heat preservation furnace 20. The weight of the metal solution 30 in the ladle 13 is the target metal solution weight.

[0066] It should be noted that this embodiment does not specifically limit the type of metal solution 30. For example, metal solution 30 can be an aluminum alloy solution, etc., and can be set according to actual needs.

[0067] It is worth noting that the soup dispensing control device can store the third relationship curves corresponding to different models of soup ladles 13. In this way, when changing to different models of soup ladles, the soup dispensing control device can still achieve the above-mentioned soup ladle tilt angle control method, thereby ensuring that the soup ladle scoops up the metal solution that meets the weight requirements, and improving the working efficiency of the soup dispensing control device.

[0068] Compared with related technologies, the embodiments of this application have at least the following advantages: By performing motion simulation on the die-casting control system, a large amount of first and second simulation data can be obtained. Since the first simulation data includes the movement distance of the transmission component and the tilt angle of the ladle corresponding to the movement distance, a first relationship curve between the movement distance and the tilt angle can be obtained from the first simulation data; similarly, a second relationship curve between the tilt angle and the weight of the molten metal can be obtained from the second simulation data. Furthermore, since the first relationship curve represents the correspondence between the tilt angle and the movement distance, and the second relationship curve represents the correspondence between the tilt angle and the weight of the molten metal, a third relationship curve between the movement distance and the weight of the molten metal can be obtained from the first and second relationship curves. Thus, after determining the target weight of the molten metal required for the die-cast product, the target movement distance of the transmission component corresponding to the target weight of the molten metal can be obtained based on the third relationship curve. Then, by controlling the movement of the transmission component through the target movement distance, the tilt angle of the ladle is automatically confirmed, ensuring that the weight of the molten metal scooped by the ladle at the target tilt angle is equal to the target weight of the molten metal, thereby improving the accuracy of the weight of the molten metal scooped by the ladle. In addition, the entire process of confirming the tilt angle of the ladle and scooping the molten metal does not require manual intervention, reducing labor costs.

[0069] Please refer to Figure 5 , Figure 5 This is a flowchart illustrating the steps of one embodiment of the die-casting control method of this application. Depending on different requirements, the order of the steps in this flowchart can be changed, and some steps can be omitted. This die-casting control method can be applied to the aforementioned die-casting control system, but is not limited thereto, and the embodiments of this application do not limit it in this regard.

[0070] This embodiment is a further improvement on the aforementioned embodiment. The main improvement is that, in this embodiment, the weight of the molten metal scooped by the ladle is also checked based on the thickness of the slurry handle to ensure it meets the preset die-casting requirements. This method further improves the accuracy of the weight of the molten metal scooped by the ladle, thereby increasing the yield of the die-cast products.

[0071] The specific process of this embodiment is as follows: Figure 5 As shown, it includes the following steps:

[0072] Perform steps 101 to 108.

[0073] Step 201: Obtain the third simulation data after performing motion simulation on the die-casting control system. The third simulation data includes the weight of the molten metal and the position of the punch in the pressure chamber.

[0074] Step 202: Determine the thickness of the shank based on the position of the punch.

[0075] To facilitate understanding, the following will be combined with... Figure 6 This embodiment provides a detailed explanation of how the third simulation data is obtained:

[0076] like Figure 6 The diagram shown is a structural schematic of the die-casting machine provided in this embodiment of the application. The die-casting machine 40 includes a pressure chamber 41, a punch 42 disposed in the pressure chamber 41, and a mold cavity 43 communicating with the pressure chamber 41; the pressure chamber 41 receives molten metal injected by the ladle 13, and the punch 42 moves within the pressure chamber 41 to form a die-cast product 50 within the mold cavity 43, the die-cast product 50 including a stalk 51 that abuts against the punch 42.

[0077] Specifically, the die-casting control system also includes a die-casting control device for operating the die-casting machine 40. The ladle 13 controls the ladle to inject the molten metal 30 into the pressure chamber 41. The die-casting control device then controls the punch 42 to move within the pressure chamber 41, causing the molten metal 30 to flow into the mold cavity 43, thereby forming the die-cast product 50. After the die-cast product 50 is formed, it has a stalk 51, which abuts against the punch 42. Therefore, the stalk thickness of the stalk 51 can be determined by the position of the punch 42 within the pressure chamber 41, thus obtaining the third simulation data.

[0078] Step 203: Based on the third simulation data and the thickness of the stalk, determine the fourth relationship curve between the weight of the molten metal and the thickness of the stalk.

[0079] In some embodiments, the fourth relationship curve is a linear curve. The method for determining the fourth relationship curve includes: establishing a plane rectangular coordinate system; using the weight of the molten metal as the abscissa of the plane rectangular coordinate system and the thickness of the stalk as the ordinate of the plane rectangular coordinate system to obtain multiple sets of first coordinate points of the molten metal weight and the stalk thickness in the plane rectangular coordinate system; and obtaining the fourth relationship curve based on the multiple sets of first coordinate points.

[0080] It is understandable that the method for determining the fourth relationship curve is the same as that for determining the first relationship curve, and will not be repeated here to avoid repetition.

[0081] Step 204: Based on the third and fourth relationship curves, obtain the fifth relationship curve between the movement distance and the thickness of the material shank.

[0082] Specifically, since the third relationship curve represents the correspondence between the movement distance and the weight of the molten metal, and the fourth relationship curve represents the correspondence between the weight of the molten metal and the thickness of the stalk, a fifth relationship curve between the movement distance and the thickness of the stalk can be obtained through the third and fourth relationship curves.

[0083] Understandably, the fourth relationship curve is also a linear curve.

[0084] Step 205: Determine the final punch position in the pressure chamber, and determine the actual shank thickness based on the final punch position.

[0085] In some embodiments, after the ladle 13 injects the molten metal 30 into the die-casting machine 40, the punch 42 moves within the pressure chamber 41 to inject the molten metal 30 into the mold cavity 43. The final punch position of the punch 42 within the pressure chamber 41 is the contact position between the punch 42 and the formed stalk 51. Figure 6 As can be seen, if there is no molten metal 30 in the pressure chamber 41 and the mold cavity 43, the punch 42 will directly abut against the bottom of the pressure chamber 41. Let's assume that the position of the punch at this time is position 1. If there is molten metal 30 in the pressure chamber 41 and the mold cavity 43, since the stalk 51 has a certain thickness, the punch 42 abuts against the stalk 51. Let's assume that the position of the punch at this time is position 2. The height difference between position 1 and position 2 is the actual stalk thickness of the stalk 51.

[0086] Step 206: Obtain the target material shank thickness corresponding to the target movement distance based on the fifth relationship curve.

[0087] In some embodiments, a fifth relationship curve is stored in the die-casting control device, and the die-casting control device sends the target movement distance of the transmission member 12 to the die-casting control device, which obtains the target material stalk thickness based on the fifth relationship curve.

[0088] Step 207: Compare the actual spool thickness with the target spool thickness, and check whether the actual weight of the molten metal scooped up by the ladle meets the preset die-casting requirements based on the comparison results.

[0089] In some embodiments, if the comparison result shows that the actual stalk thickness is not equal to the target stalk thickness, the actual molten metal weight is detected as not meeting the preset die-casting requirements; if the comparison result shows that the actual stalk thickness is equal to the target stalk thickness, the actual molten metal weight is detected as meeting the preset die-casting requirements.

[0090] In some embodiments, after detecting that the actual molten metal weight does not meet the preset die-casting requirements, the thickness difference between the target stalk thickness and the actual stalk thickness is calculated; the molten metal weight compensation value corresponding to the thickness difference is obtained according to the fourth relationship curve; the molten metal weight compensation value and the target molten metal weight are added together to obtain the molten metal weight sum; the corrected tilt angle corresponding to the molten metal weight sum is determined according to the second relationship curve; during the die-casting process of the next product to be die-cast, the ladle is controlled to scoop the molten metal at the corrected tilt angle.

[0091] Because the ladle may oxidize or retain some solidified molten metal residue during the process of scooping the molten metal, the weight of the molten metal scooped by the ladle after rotating it to the target tilt angle will deviate from the target weight of the molten metal required for the die-casting product. Furthermore, since the thickness of the stalk of the die-casting product is the same for a given weight of molten metal scooped by the ladle, this embodiment determines whether the actual weight of the molten metal scooped by the ladle meets the preset die-casting requirements by detecting the thickness difference between the target stalk thickness and the actual stalk thickness. If the actual weight of the molten metal does not meet the preset die-casting requirements, the molten metal weight compensation value can be accurately determined through the thickness difference and the fourth relationship curve. By adding the molten metal weight compensation value to the target molten metal weight, a sum of molten metal weights is obtained. Then, based on the second relationship curve, a corrected tilt angle corresponding to the sum of molten metal weights is determined. By controlling the ladle to scoop the molten metal at the corrected tilt angle, compensation for the actual weight of the molten metal scooped by the ladle can be achieved, ensuring that the actual weight of the molten metal scooped by the ladle is equal to the target molten metal weight, thus improving the yield of the die-casting product.

[0092] Compared with related technologies, the embodiments of this application have at least the following advantages: By performing motion simulation on the die-casting control system, a large amount of first and second simulation data can be obtained. Since the first simulation data includes the movement distance of the transmission component and the tilt angle of the ladle corresponding to the movement distance, a first relationship curve between the movement distance and the tilt angle can be obtained from the first simulation data; similarly, a second relationship curve between the tilt angle and the weight of the molten metal can be obtained from the second simulation data. Furthermore, since the first relationship curve represents the correspondence between the tilt angle and the movement distance, and the second relationship curve represents the correspondence between the tilt angle and the weight of the molten metal, a third relationship curve between the movement distance and the weight of the molten metal can be obtained from the first and second relationship curves. Thus, after determining the target weight of the molten metal required for the die-cast product, the target movement distance of the transmission component corresponding to the target weight of the molten metal can be obtained based on the third relationship curve. Then, by controlling the movement of the transmission component through the target movement distance, the tilt angle of the ladle is automatically confirmed, ensuring that the weight of the molten metal scooped by the ladle at the target tilt angle is equal to the target weight of the molten metal, thereby improving the accuracy of the weight of the molten metal scooped by the ladle. In addition, the entire process of confirming the tilt angle of the ladle and scooping the molten metal does not require manual intervention, reducing labor costs.
