The specific value can be determined according to the size, weight or volume of the casting device. It is noted that in embodiments of the invention, the first rate is the rate at which the reservoir rises; the second rate is a rate of casting liquid flowing into the second opening; the third rate may be a rate at which the liquid metal rises within a predetermined mold, which is considered herein as a rate at which a cast device is formed. In the casting process, if the rising speed of the casting liquid in the cavity of the preset mold is too high, splashing and turbulence are easily generated; if the rate is too slow, the mold filling time is easily long, the temperature of the molten metal drops quickly, and the defect of insufficient casting is formed. After the third rate is determined, the amount of casting liquid required by the casting device is determined, and then the time required for filling the cavity can be determined; the pouring liquid enters the cavity of the preset mold through the second opening, and the amount of the pouring liquid passing through the second opening in unit time can be determined according to the total amount and time, so that the area of the second opening is determined; the third speed is formed by the height difference formed by the height of the liquid level in the liquid storage container and the height of the liquid level in the preset mold; this difference in height can be controlled by the level of the liquid level formed after the rise of the reservoir. It is noted that in the embodiment of the invention, the height of the lowest edge of the second opening 15 is not higher than the height of the lowest edge of the first opening when the reservoir is raised to the highest position, as shown in fig. 3, so as to ensure that the pouring liquid in the reservoir 11 is sufficiently discharged when the reservoir 11 is raised to the highest position. Meanwhile, the height of the lowest edge of the second opening 15 is not lower than the height of the highest edge of the first opening 14 when the liquid storage container 11 descends to the lowest position, as shown in fig. 4, so that the pouring process is started after the liquid storage container 11 starts to ascend, the rate of pouring liquid flowing into a preset mold is controllable, the phenomenon that the pouring liquid does not start to ascend and flows into the preset mold to cause uncontrollable pouring rate is avoided, and the yield of pouring devices is effectively guaranteed.
