[0023] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The following describes a metal fluid casting method, a casting device, and a metal fluid casting and molding equipment according to embodiments of the present invention with reference to the accompanying drawings.

[0025] Figure 1 The present invention is a flowchart of a method for casting a metal fluid according to an embodiment of the present invention.

[0026] The method is used for a casting device, which comprises a tilting mechanism, and the tilting mechanism is used to drive a container containing a metal fluid to tilt so as to pour the metal fluid in the container into a vibrating cooling platform.

[0027] It should be noted that the casting method of the metal fluid is not limited to the type of metal fluid, as long as it is a metal fluid with fluid properties, such as a high-temperature solution of ferroalloy, etc. Moreover, even a metal-like fluid can be applied to the casting method of the metal fluid in the embodiment of the present invention. For example, this method can also be used for metal-like fluids such as high-temperature solutions of industrial silicon.

[0028] like Figure 1 As shown, the casting method of metal fluid comprises:

[0029] S11, when the tilting mechanism drives the container to tilt, the total weight of the container and the casting device is obtained at a first preset time interval.

[0030] S12, obtaining the current weight change of the metal fluid according to the total weight obtained from two consecutive times.

[0031] S13, controlling the tilting mechanism according to the current weight change and the target casting time, so that the tilting mechanism completes the casting of the metal fluid within the target casting time.

[0032] Specifically, in the process of the tilting mechanism driving the container to tilt, the total weight of the container and the casting device is obtained every first preset time. Obviously, since the container contains metal fluid, the total weight of the container and the casting device is the sum of the weights of the above-mentioned container, metal fluid and casting device. Since the weight of the container and the casting device will not change in the process of the tilting mechanism driving the container to tilt, the current weight change of the metal fluid within the first preset time can be obtained by subtracting the total weights obtained two adjacent times.

[0033] After obtaining the current weight change, it can be determined whether the current weight change meets the conditions according to the target casting time, that is, whether the tilting mechanism can complete the casting of the metal fluid within the target casting time according to the current tilting speed according to the current weight change. If it is not possible, the tilting mechanism is controlled according to the current weight change and the target casting time, so as to complete the casting of the metal fluid within the target casting time.

[0034] The above target casting time is a preset time, which can be obtained by the user according to experience, historical data, design requirements and other rules. Obviously, since the above metal fluid casting method can achieve the casting of the metal fluid within the target casting time, when the method is applied, the speed of the metal fluid flowing onto the vibration cooling platform can be adjusted by adjusting the target casting time.

[0035] The casting method of the metal fluid according to the embodiment of the present invention can realize automatic casting, improve the controllability of the operation, reduce manual participation, and improve safety.

[0036] In some embodiments, obtaining the total weight of the container and the casting device includes: sampling the total weight of the container and the casting device through a weight sensor disposed at the bottom of the casting device to obtain the total weight.

[0037] In some embodiments, the value range of the first preset time is 1ms to 9ms, and the tilting mechanism is controlled according to the current weight change and the target casting time, including: obtaining the standard weight change according to the target casting time and the initial weight of the metal fluid; when the current weight change is less than the standard weight change, increasing the tilting speed of the tilting mechanism.

[0038] Specifically, in order to control the tipping mechanism according to the current weight change and the target casting time, the standard weight change is first obtained according to the target casting time and the initial weight of the metal fluid.

[0039] In order to obtain the standard weight change, the initial weight of the metal fluid can be directly divided by the target casting time to obtain the required weight change per unit time, and then the standard weight change is obtained according to the required weight change per unit time and the duration of the first preset time. In other words, the standard weight change is the weight of the liquid cast within the first preset time in order to complete the casting of the metal fluid within the target casting time.

[0040] Obviously, in actual applications, the tilting mechanism cannot achieve the standard weight change of the amount of liquid poured within the first preset time immediately after starting to tilt. Therefore, it is necessary to set a shorter value range of the first preset time to achieve rapid control of the tilting mechanism and prevent timeout.

[0041] Based on this, the value range of the first preset time is set to 1ms to 9ms.

[0042] In some embodiments, controlling the tilting mechanism according to the current weight change and the target casting time further includes: when the current weight change is greater than the standard weight change, reducing the tilting speed of the tilting mechanism.

[0043] That is to say, it can also be set that when the current weight change is greater than the standard weight change, the tipping speed of the tipping mechanism is reduced, so as to complete the casting of the metal fluid accurately at the end of the target casting time. The optimal casting effect can be achieved according to the setting of the target casting time, the quality of the casting results can be improved, and the production efficiency can be improved.

[0044] In some embodiments, the tilting mechanism also includes a proportional valve and a tilting cylinder; increasing the tilting speed of the tilting mechanism includes: obtaining a current tilting speed based on a current weight change, and obtaining a target tilting speed based on a standard weight change; obtaining a target current increase value based on the current tilting speed and the target tilting speed; obtaining a target current based on the target current increase value and the current current; and outputting the target current to the proportional valve to push the container to tilt through the tilting cylinder.

[0045] Specifically, when the current weight variation is less than the standard weight variation, it indicates that the weight variation needs to be increased, and in order to increase the weight variation, the tilting speed of the tilting mechanism needs to be increased. In order to increase the tilting speed of the tilting mechanism, the tilting angle of the container needs to be increased.

[0046] Therefore, when the current weight change is less than the standard weight change, the current tilting speed is obtained according to the current weight change, and the target tilting speed is obtained according to the standard weight change. Since the tilting speed is controlled by the proportional valve, the current that the proportional valve needs to increase can be obtained according to the current tilting speed and the target tilting speed. The current that needs to be increased is the target current increase value, and then the target current is obtained according to the target current increase value and the current current, so that the proportional valve is controlled according to the target current.

[0047] Combine the following Figure 2 and Figure 3 The specific embodiment shown is described below. Figure 3 In the figure, 7 is a container and 8 is a lug.

[0048] Specifically, Figure 2 As shown, the tilting mechanism includes: a bracket 1, a fixed base 2, a tilting cylinder 3, a latch mechanism 4, an angle sensor 5, and a weight sensor 6. Among them, the container 7 can be a silicon bag, and the silicon bag is provided with a lug 8. The tilting angle change of the tilting mechanism 3 is obtained in real time through the angle sensor 5. The bracket 1 is installed on the fixed base 2, and the bracket 1 is used to support the container 7 containing the metal fluid. The weight sensor 5 is arranged at the bottom of the fixed base 2, and the fixed end of the tilting cylinder 3 is arranged on the fixed base 2. The moving end of the tilting cylinder 3 is used to push the container 7 to tilt. The tilting cylinder 3 can push the container 7 under the control of the proportional valve.

[0049] When the equipment is started, the tilting mechanism tilts to the set angle, and the silicon bag is transported by the silicon bag trolley. After the sensor determines that the silicon bag is in place, the latch mechanism 4 opens, the tilting mechanism falls back to its original position, and the latch mechanism 4 is inserted into the silicon bag ear 8. The tilting mechanism automatically tilts, and the weight is measured by the weight sensor 6 installed at the bottom of the tilting mechanism. In addition, the initial weight of the metal fluid can be obtained based on the weight measured at the starting time.

[0050] Because the container 7 is always in motion during the pouring process, it is not convenient to measure the weight directly, and the center of gravity of the weighing is constantly changing. In order to make the measurement more convenient and reliable, the weight sensor 6 is arranged under the fixed base 2 to measure the total weight of the container 7 and the casting device. The weight sensor 6 measures the container 7 and the casting device in the initial state to obtain the total weight m. After that, the weight sensor 6 collects and obtains the total weight every first preset time △t, and obtains the weight data in time sequence: (m1, t1), (m2, t2), (m3, t3), (m4, t4)...(mn-1, tn-1), (mn, tn), and saves it in the real-time data analysis database; for each collected data, the weight of the casting device and the empty container 7 is subtracted from the total weight to obtain the weight of the metal fluid. Among them, the first preset time △t can be accurate to 1-9 milliseconds.

[0051] The total weight of two consecutive samples is subtracted to obtain the weight of the metal fluid flowing out of the container 7 during the first preset time. The initial weight of the metal fluid is obtained by subtracting the weight of the empty container 7 and the weight of the casting device from the total weight m.

[0052] The value obtained by dividing the initial weight of the metal fluid by the target casting time is the weight of the liquid flowing out per theoretical unit time. The above-mentioned standard weight change can be obtained based on the weight of the liquid flowing out per theoretical unit time and the duration of the first preset time.

[0053] The controller controls the output of the proportional valve of the tilting mechanism, and obtains the actual weight change within the first preset time according to the weight collected by the sensor, which is the current weight change.

[0054] The controller compares the current weight change with the standard weight change, and adjusts the proportional valve output current through PID to make the two values ​​consistent within the unit time interval. It should be noted that if the weight difference between the two does not exceed the error value detected by the sensor within the unit time interval, the theoretical and actual values ​​are considered consistent.

[0055] The value obtained by dividing the proportional valve output current by the proportional valve full-scale current and multiplying it by 100% is the proportional valve output percentage, that is, the tipping speed.

[0056] The tilting mechanism can also be provided with a position sensor, and the use status of the tilting mechanism can also be seen in Figure 3 , the tilting cylinder 3 is pushed out to make the tilting mechanism tilt.

[0057] In some embodiments, the method further includes: if the current weight change is zero, confirming that the casting is completed.

[0058] In some embodiments, Figure 4 As shown, the casting device also includes a fixing assembly, and before the tipping mechanism drives the container to tip, the method also includes:

[0059] S71, controlling the tilting mechanism to tilt to a preset angle.

[0060] S72, when the transport device transports the container containing the metal fluid to a preset position near the casting device, the tilting mechanism is controlled to fall back to the initial position, and the fixing component is controlled to fix the container on the tilting mechanism. The fixing component may be a latch mechanism 4.

[0061] In this embodiment, if Figure 2 and Figure 3 As shown, when the casting device is started, the tilting mechanism tilts to a preset angle, and the silicon bag is transported to the tilting cylinder 3 by the silicon bag trolley. After the position sensor determines that the silicon bag has reached the preset position, the latch mechanism 4 opens, and the tilting mechanism falls back to the initial position. The latch mechanism 4 is inserted into the silicon bag ear. After the latch mechanism 4 buckles the ear, the tilting cylinder 3 pushes out to tilt the tilting mechanism.

[0062] The above preset angle is to tilt the tipping mechanism over the height of the silicon bag to prevent interference so that the silicon bag cannot enter the tipping position. Similarly, after the casting is completed, it needs to fall back to the horizontal position, and after the latch mechanism is opened, the tipping mechanism needs to be tilted again to at least the same angle as the preset angle, so that the silicon bag transport vehicle can exit.

[0063] In some embodiments, after confirming that the casting is completed, the method also includes: controlling the fixing assembly to release the container from the tilting mechanism, controlling the tilting mechanism to tilt to a preset angle, and controlling the fixing assembly to release the container from the tilting mechanism so that the transportation equipment can transport the container away from the casting device.

[0064] The fixing component may be a latch mechanism 4. In this embodiment, the tilting mechanism falls back, the latch mechanism 4 opens, and then the tilting mechanism tilts again to a preset angle, the transport device takes the container away, and the casting is finished.

[0065] To sum up, the casting method of metal fluid according to the embodiment of the present invention can replace the manual casting operation mode, effectively reduce the casting risk, and adopt automatic control for continuous and efficient operation, which can ensure that the casting is carried out effectively and smoothly, reduce equipment downtime, increase production capacity, and has a simple operation method and can obtain more stable product quality; automatic casting can effectively reduce the participation of on-site personnel and reduce the safety risks faced by production personnel.
