Description

Technical Field

[0001] The present 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 Art

[0002] When the die-casting machine is die-casting aluminum alloy or zinc alloy products, the aluminum alloy or zinc alloy solution needs to be poured into the melting cup of the die-casting machine. The traditional method is to pour the material manually. It is difficult to control the amount of solution during manual pouring, and safety accidents are prone to occur. In order to reduce the labor intensity of workers and save labor costs, a soup feeder is needed to replace manual metal pouring. The working principle of the soup feeder is as follows: set the soup spoon's soup taking angle in the soup feeder, sink the soup spoon into the aluminum alloy liquid according to the set angle and then slowly lift it up, and the excess aluminum alloy liquid flows out of the soup spoon through the tilted angle of the soup spoon. The remaining aluminum alloy liquid in the soup spoon is the liquid weight required for the die-cast product.

[0003] In the related art, the operator blindly sets the angle of the soup spoon to complete the setting of the soup taking angle based on the size of the soup spoon and the liquid weight requirement of the die-cast product, relying on experience or guesswork. This method will result in low accuracy in the weight of the liquid scooped by the soup spoon, and it is necessary to manually confirm the final soup taking angle of the soup spoon through repeated comparisons, which greatly increases the labor cost. Summary of the invention

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

[0005] The embodiment of the present application provides a die-casting control method, which is applied to a die-casting control system, wherein the die-casting control system includes a soup feeder; the soup feeder includes a transmission member and a soup spoon connected to the transmission member, wherein the movement of the transmission member drives the soup spoon to rotate so that the soup spoon is at different tilt angles; the method includes: obtaining first simulation data and second simulation data after motion simulation of the die-casting control system, wherein the first simulation data includes a movement distance of the transmission member and a tilt angle of the soup spoon corresponding to the movement distance, and the second simulation data includes the tilt angle and a weight of the metal solution scooped by the soup spoon corresponding to the tilt angle; according to 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 metal solution; the third relationship curve between the movement distance and the weight of the metal solution is obtained according to the first relationship curve and the second relationship curve; the target weight of the metal solution required for the die-cast product is determined; the target movement distance of the transmission member corresponding to the target weight of the metal solution is obtained according to the third relationship curve; the movement of the transmission member is controlled according to the target movement distance so that the spoon is rotated to the target tilt angle; the spoon is controlled to scoop the metal solution at the target tilt angle.

[0006] Compared with the related art, the embodiment of the present application has at least the following advantages: by performing motion simulation on the die-casting control system, a large amount of first simulation data and second simulation data can be obtained. Since the first simulation data includes the movement distance of the transmission member and the tilt angle of the soup spoon corresponding to the movement distance, the first relationship curve between the movement distance and the tilt angle can be obtained through the first simulation data; similarly, the second relationship curve between the tilt angle and the weight of the metal solution can be obtained through the second simulation data. Since the first relationship curve represents the corresponding relationship between the tilt angle and the movement distance, and the second relationship curve represents the corresponding relationship between the tilt angle and the weight of the metal solution, the third relationship curve between the movement distance and the weight of the metal solution can be obtained through the first relationship curve and the second relationship curve. Therefore, after determining the target weight of the metal solution required for the die-cast product, the target movement distance of the transmission member corresponding to the target weight of the metal solution can be obtained based on the third relationship curve, and then the movement of the transmission member is controlled by the target movement distance, thereby realizing the automatic confirmation of the tilt angle of the soup spoon, so that the weight of the metal solution scooped by the soup spoon rotated to the target tilt angle can be equal to the target weight of the metal solution, and the accuracy of the weight of the metal solution scooped by the soup spoon is improved. In addition, the entire process of confirming the tilt angle of the spoon and scooping the metal solution does not require human intervention, reducing labor costs.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0031] Please refer to Figure 1 , which is a flow chart of the die-casting control method provided in an embodiment of the present application. This embodiment is applied to a die-casting control system, and the die-casting control system includes a soup feeder; the soup feeder includes a transmission member and a soup spoon connected to the transmission member, and the movement of the transmission member drives the soup spoon to rotate so that the soup spoon is at different inclination angles.

[0032] The die casting control method of this embodiment includes the following steps: Step 101: Acquire first simulation data and second simulation data after performing motion simulation on a die-casting control system.

[0033] Specifically, the first simulation data includes the movement distance of the transmission member and the tilt angle of the spoon corresponding to the movement distance, and the second simulation data includes the tilt angle of the spoon and the weight of the molten metal scooped by the spoon corresponding to the tilt angle.

[0034] In some embodiments, the process of motion simulation of the die-casting control system is as follows: the die-casting control system drives the transmission member to move, so that the transmission member drives the soup spoon to rotate, so that the soup spoon is at different tilt angles. In other words, each movement distance of the transmission member corresponds to a tilt angle of the soup spoon.

[0035] Please refer to Figure 2 , Figure 2 The following are application scenarios of scooping metal solution with a spoon at different tilt angles. Figure 2 It can be seen from the figure that when the spoon is at different tilt angles, the weight of the metal solution scooped from the spoon is different. In other words, each tilt angle of the spoon corresponds to the weight of the metal solution scooped from the spoon.

[0036] It can be 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 the subsequent embodiments. In order to avoid repetition, it will not be repeated here.

[0037] Step 102: Determine a first relationship curve between the movement distance of the transmission member and the tilt angle of the soup spoon according to the first simulation data.

[0038] In some embodiments, the first relationship curve is a linear curve, and the method for determining the first relationship curve includes: establishing a plane rectangular coordinate system; using the movement distance as the horizontal coordinate of the plane rectangular coordinate system, and the inclination angle as the vertical coordinate of the plane rectangular coordinate system, to obtain multiple groups of second coordinate points of the first simulation data in the plane rectangular coordinate system; and obtaining the first relationship curve based on the multiple groups of second coordinate points.

[0039] For ease of understanding, the following specifically describes how to obtain the first relationship curve in this embodiment by taking the first simulation data including the movement distances of 100 sets of transmission parts and the tilt angles of soup spoons as an example: The movement distance of each set of transmission parts and the tilt angle of the soup spoon corresponding to the movement distance are converted into second coordinate points to obtain 100 sets of second coordinate points. The first relationship curve corresponding to the 100 discrete second coordinate points is determined by linear fitting, such as the least squares method.

[0040] Step 103: Determine a second relationship curve between the tilt angle of the spoon and the weight of the metal solution according to the second simulation data.

[0041] 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 inclination angle as the horizontal coordinate of the plane rectangular coordinate system, and the weight of the metal solution as the vertical coordinate of the plane rectangular coordinate system, to obtain multiple groups of third coordinate points of the second simulation data in the plane rectangular coordinate system; based on the multiple groups of third coordinate points, obtaining the second relationship curve.

[0042] It can be understood that the second relationship curve is determined in the same manner as the first relationship curve, and will not be described again here to avoid repetition.

[0043] Step 104: Obtain a third relationship curve between the movement distance of the transmission member and the weight of the metal solution according to the first relationship curve and the second relationship curve.

[0044] 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 metal solution, the third relationship curve between the movement distance and the weight of the metal solution can be obtained through the first relationship curve and the second relationship curve.

[0045] It can be understood that the third relationship curve is also a linear curve.

[0046] Step 105: Determine the target molten metal weight required for the product to be die-cast.

[0047] In some embodiments, an operator inputs a target molten metal weight via a die casting control system.

[0048] In some embodiments, the die-casting control system pre-stores the metal solution weights corresponding to different types of products to be die-casted, and the operator can also select the type of product to be die-casted in the die-casting control system, and the die-casting control system determines the target metal solution weight corresponding to the type.

[0049] It is understandable that this embodiment does not specifically limit the method for determining the target metal solution weight, and it can be set according to actual needs.

[0050] Step 106: Obtaining a target movement distance of the transmission member corresponding to the target metal solution weight according to the third relationship curve.

[0051] Specifically, since the third relationship curve represents the corresponding relationship between the weight of the metal solution and the movement distance, the third relationship curve is pre-stored in the die casting control system. Therefore, after the die casting control system obtains the target weight of the metal solution, the target movement distance corresponding to the target weight of the metal solution can be obtained according to the third relationship curve.

[0052] Step 107: Control the movement of the transmission member according to the target movement distance, so that the spoon rotates to the target tilt angle.

[0053] Specifically, the die-casting control system controls the target movement distance of the transmission part, and the spoon will rotate to a target tilt angle corresponding to the target movement distance. The weight of the molten metal scooped by the spoon at the target tilt angle is equal to the target weight of the molten metal.

[0054] Step 108: Control the spoon to scoop up the metal solution at a target tilt angle.

[0055] In some embodiments, the die casting control system further comprises a soup feeding control device for controlling the soup feeding machine, wherein the soup feeding control device controls the movement of the soup feeding machine so that the soup spoon scoops up the molten metal.

[0056] For ease of understanding, the following Figure 3 and Figure 4 How the soup feeding control device of this embodiment controls the soup spoon to scoop up the metal solution is specifically described: Please refer to Figure 3 , Figure 3The schematic diagram of the structure of the soup feeder provided in the embodiment of the present application. The soup feeder 10 includes a mounting member 11, a transmission member 12 and a soup spoon 13, wherein the soup spoon 13 is rotatably connected to the mounting member 11, the transmission member 12 is connected to the soup spoon 13, and the connection between the transmission member 12 and the soup spoon 13 and the connection between the mounting member 11 and the soup spoon 13 are spaced apart, so that the transmission member 12 can drive the soup spoon 13 to rotate relative to the mounting member 11 and scoop up the metal solution.

[0057] Specifically, Figure 4 The transmission member 12 shown drives the soup spoon 13 to rotate by moving in the vertical direction, and the rising and falling heights of the transmission member 12 determine the rotation angle of the soup spoon 13.

[0058] Please refer to Figure 4 , which is a diagram of an application scenario of a soup spoon provided in an embodiment of the present application to scoop up molten metal in a heat preservation furnace. Figure 4 Holding furnace 20 is shown having molten metal 30 therein.

[0059] like Figure 4 As shown in (a) of FIG. 8 , the soup feeding control device controls the soup feeding machine 10 to move so that the soup ladle 13 is located above the heat-insulating furnace 20 .

[0060] like Figure 4 As shown in (b) of FIG. 1 , the soup feeding control device controls the transmission member 12 to move a target movement distance in the vertical direction so that the soup spoon 13 rotates to a target tilt angle. Figure 3 It can be seen that the rise of the transmission member 12 will cause the inclination angle of the soup spoon 13 to become smaller, and the fall of the transmission member 12 will cause the inclination angle of the soup spoon 13 to become larger. Therefore, in this embodiment, the rise or fall of the transmission member 12 can be represented by the positive or negative value of the movement distance. For example, when the movement distance is -5 cm, the soup feeding control device controls the transmission member 12 to fall by 5 cm, and when the movement distance is 10 cm, the soup feeding control device controls the transmission member 12 to rise by 10 cm.

[0061] like Figure 4 As shown in (c) , the soup feeding control device controls the soup feeding machine 10 to move downward so that the soup ladle 13 is located in the heat preservation furnace 20 , and the metal solution 30 flows into the soup ladle 13 .

[0062] like Figure 4 As shown in (d), after the spoon 13 scoops up the metal solution 30, the soup feeding control device controls the soup feeding machine 10 to move upward so that the spoon 13 is located above the insulation furnace 20 again, and the weight of the metal solution 30 in the spoon 13 is the target metal solution weight.

[0063] It should be noted that the present embodiment does not specifically limit the type of the metal solution 30 . For example, the metal solution 30 may be an aluminum alloy solution, etc., and may be configured according to actual needs.

[0064] It is worth noting that the soup feeding control device can store the third relationship curves corresponding to different types of soup spoons 13. In this way, when different types of soup spoons are replaced, the soup feeding control device can also implement the above-mentioned soup spoon tilt angle control method, thereby ensuring that the soup spoon scoops up the metal solution that meets the weight requirement, thereby improving the working efficiency of the soup feeding control device.

[0065] Compared with the related art, the embodiment of the present application has at least the following advantages: by performing motion simulation on the die-casting control system, a large amount of first simulation data and second simulation data can be obtained. Since the first simulation data includes the movement distance of the transmission member and the tilt angle of the soup spoon corresponding to the movement distance, the first relationship curve between the movement distance and the tilt angle can be obtained through the first simulation data; similarly, the second relationship curve between the tilt angle and the weight of the metal solution can be obtained through the second simulation data. Since the first relationship curve represents the corresponding relationship between the tilt angle and the movement distance, and the second relationship curve represents the corresponding relationship between the tilt angle and the weight of the metal solution, the third relationship curve between the movement distance and the weight of the metal solution can be obtained through the first relationship curve and the second relationship curve. Therefore, after determining the target weight of the metal solution required for the die-cast product, the target movement distance of the transmission member corresponding to the target weight of the metal solution can be obtained based on the third relationship curve, and then the movement of the transmission member is controlled by the target movement distance, thereby realizing the automatic confirmation of the tilt angle of the soup spoon, so that the weight of the metal solution scooped by the soup spoon rotated to the target tilt angle can be equal to the target weight of the metal solution, and the accuracy of the weight of the metal solution scooped by the soup spoon is improved. In addition, the entire process of confirming the tilt angle of the spoon and scooping the metal solution does not require human intervention, reducing labor costs.

[0066] Please refer to Figure 5 , Figure 5 This is a flowchart of the steps of an embodiment of the die casting control method of the present application. According to different requirements, the order of the steps in the flowchart can be changed, and some steps can be omitted. The die casting control method can be applied to the aforementioned die casting control system, but is not limited thereto, and the embodiments of the present application do not limit this.

[0067] This embodiment is a further improvement of the above embodiment, and the main improvement is that in this embodiment, the weight of the molten metal scooped by the spoon is also detected based on the thickness of the material handle to see whether it meets the preset die-casting requirements. In this way, the accuracy of the weight of the molten metal scooped by the spoon can be further improved, thereby improving the yield rate of the die-cast product.

[0068] The specific process of this embodiment is as follows Figure 5 As shown, the following steps are included: Execute steps 101 to 108.

[0069] Step 201: Acquire third simulation data after motion simulation of the die-casting control system, wherein the third simulation data includes the weight of the molten metal and the punch position of the punch in the pressure chamber.

[0070] Step 202: Determine the thickness of the material handle according to the punch position.

[0071] For ease of understanding, the following Figure 6 How to obtain the third simulation data in this embodiment is specifically described: like Figure 6 , which is a schematic diagram of the structure of the die-casting machine provided in the embodiment of the present application. The die-casting machine 40 includes a pressure chamber 41, a punch 42 disposed in the pressure chamber 41, and a die cavity 43 connected to the pressure chamber 41; the pressure chamber 41 receives the molten metal injected by the spoon 13, and the punch 42 moves in the pressure chamber 41 to form a die-cast product 50 in the die cavity 43, and the die-cast product 50 includes a material handle 51 abutting against the punch 42.

[0072] Specifically, the die-casting control system also includes a die-casting control device for controlling the die-casting machine 40. After the soup feeding control device controls the soup spoon 13 to inject the scooped metal solution 30 into the pressure chamber 41, the die-casting control device controls the punch 42 to move in the pressure chamber 41, so that the metal solution 30 flows into the mold cavity 43, thereby forming the product to be die-cast 50. After the die-cast product 50 is formed, it has a material handle 51, and the material handle 51 abuts against the punch 42. Therefore, the material handle thickness of the material handle 51 can be determined by the punch position of the punch 42 in the pressure chamber 41, thereby obtaining the third simulation data.

[0073] Step 203: Determine a fourth relationship curve between the weight of the metal solution and the thickness of the material handle according to the third simulation data and the thickness of the material handle.

[0074] In some embodiments, the fourth relationship curve is a linear curve. The fourth relationship curve is determined by: establishing a plane rectangular coordinate system; using the weight of the metal solution as the abscissa of the plane rectangular coordinate system and the thickness of the material handle as the ordinate of the plane rectangular coordinate system to obtain multiple groups of first coordinate points of the weight of the metal solution and the thickness of the material handle in the plane rectangular coordinate system; and obtaining the fourth relationship curve according to the multiple groups of first coordinate points.

[0075] It can be understood that the fourth relationship curve is determined in the same manner as the first relationship curve, and will not be described again to avoid repetition.

[0076] Step 204: Obtain a fifth relationship curve between the movement distance and the material handle thickness according to the third relationship curve and the fourth relationship curve.

[0077] Specifically, since the third relationship curve represents the correspondence between the movement distance and the weight of the metal solution, and the fourth relationship curve represents the correspondence between the weight of the metal solution and the thickness of the material handle, the fifth relationship curve between the movement distance and the thickness of the material handle can be obtained through the third relationship curve and the fourth relationship curve.

[0078] It can be understood that the fourth relationship curve is also a linear curve.

[0079] Step 205: Determine the final punch position of the punch in the pressing chamber, and determine the actual material handle thickness of the material handle according to the final punch position.

[0080] In some embodiments, after the spoon 13 injects the scooped molten metal 30 into the die casting machine 40, the punch 42 moves in the pressure chamber 41 to inject the molten metal 30 into the die cavity 43, and the final punch position of the punch 42 in the pressure chamber 41 is the abutment position between the punch 42 and the formed material handle 51. Figure 6 It can be seen that if there is no molten metal 30 in the pressure chamber 41 and the die cavity 43, the punch 42 will directly abut against the bottom of the pressure chamber 41, and it is assumed that the punch position at this time is position 1; if there is molten metal 30 in the pressure chamber 41 and the die cavity 43, since the material handle 51 has a certain thickness, the punch 42 abuts against the material handle 51, and it is assumed that the punch position at this time is position 2, and the height difference between position 1 and position 2 is the actual material handle thickness of the material handle 51.

[0081] Step 206: Obtain a target material handle thickness corresponding to the target movement distance according to the fifth relationship curve.

[0082] In some embodiments, a fifth relationship curve is stored in the die casting control device, the feed control device sends the target movement distance of the transmission member 12 to the die casting control device, and the die casting control device obtains the target material handle thickness based on the fifth relationship curve.

[0083] Step 207: Compare the actual material handle thickness with the target material handle thickness, and detect whether the actual weight of the molten metal scooped by the spoon meets the preset die-casting requirements based on the comparison result.

[0084] In some embodiments, when the comparison result is that the actual material handle thickness is not equal to the target material handle thickness, the actual metal solution weight is detected to not meet the preset die-casting requirements; when the comparison result is that the actual material handle thickness is equal to the target material handle thickness, the actual metal solution weight is detected to meet the preset die-casting requirements.

[0085] In some embodiments, after detecting that the actual weight of the metal solution does not meet the preset die-casting requirements, the thickness difference between the target material handle thickness and the actual material handle thickness is also calculated; the metal solution weight compensation value corresponding to the thickness difference is obtained according to the fourth relationship curve; the metal solution weight compensation value and the target metal solution weight are added to obtain the metal solution weight sum; the corrected tilt angle corresponding to the metal solution weight sum is determined according to the second relationship curve; during the die-casting process of the next product to be die-cast, the spoon is controlled to scoop the metal solution at the corrected tilt angle.

[0086] Since the spoon may be oxidized or some of the metal solution may remain solidified during the process of scooping the metal solution with the spoon, after the spoon is rotated to the target tilt angle, the weight of the metal solution scooped by the spoon deviates from the target weight of the metal solution required for the die-cast product. In addition, since the thickness of the handle of the molded product to be die-cast is the same when the weight of the metal solution scooped by the spoon is constant, the present embodiment determines whether the actual weight of the metal solution scooped by the spoon meets the preset die-casting requirements by detecting the thickness difference between the target handle thickness and the actual handle thickness. In the case that the actual weight of the metal solution does not meet the preset die-casting requirements, the metal solution weight compensation value can be accurately obtained through the thickness difference and the fourth relationship curve, and the metal solution weight and value are obtained by adding the metal solution weight compensation value and the target metal solution weight, and then the correction tilt angle corresponding to the metal solution weight and value is determined based on the second relationship curve. By controlling the spoon to scoop the metal solution at the correct tilt angle, the actual weight of the metal solution scooped by the spoon can be compensated, ensuring that the actual weight of the metal solution scooped by the spoon can be equal to the target weight of the metal solution, thereby improving the yield of the product to be die-cast.

[0087] Compared with the related art, the embodiment of the present application has at least the following advantages: by performing motion simulation on the die-casting control system, a large amount of first simulation data and second simulation data can be obtained. Since the first simulation data includes the movement distance of the transmission member and the tilt angle of the soup spoon corresponding to the movement distance, the first relationship curve between the movement distance and the tilt angle can be obtained through the first simulation data; similarly, the second relationship curve between the tilt angle and the weight of the metal solution can be obtained through the second simulation data. Since the first relationship curve represents the corresponding relationship between the tilt angle and the movement distance, and the second relationship curve represents the corresponding relationship between the tilt angle and the weight of the metal solution, the third relationship curve between the movement distance and the weight of the metal solution can be obtained through the first relationship curve and the second relationship curve. Therefore, after determining the target weight of the metal solution required for the die-cast product, the target movement distance of the transmission member corresponding to the target weight of the metal solution can be obtained based on the third relationship curve, and then the movement of the transmission member is controlled by the target movement distance, thereby realizing the automatic confirmation of the tilt angle of the soup spoon, so that the weight of the metal solution scooped by the soup spoon rotated to the target tilt angle can be equal to the target weight of the metal solution, and the accuracy of the weight of the metal solution scooped by the soup spoon is improved. In addition, the entire process of confirming the tilt angle of the spoon and scooping the metal solution does not require human intervention, reducing labor costs.
