[0040] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0041] In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

In a specific implementation, the control system controls the operation of the heating component to heat the smelting pot 31 (for melting the metal) and maintain the smelting pot 31 in a set temperature range (to keep the molten metal at an appropriate temperature). Subsequently, the control system controls the flow regulating component 4 to adjust the conduction cross-section between the casting pipe 32 and the smelting pot 31, so as to accurately control the flow of the molten metal. After a predetermined amount of molten metal is cast, the control system controls the flow regulating component 4 to operate and discontinue conduction between the casting pipe 32 and the smelting pot 31, thereby stopping the casting of the molten metal.

[0043] Furthermore, the present solution may be provided with a rotatable casting table 14 in the vacuum chamber 1, the casting table 14 is connected to a rotating motor 15 (the rotating motor 15 is connected to a control system), and a plurality of molds 2 are provided on the upper end surface of the casting table 14 and at intervals along its rotation direction. The rotation trajectory of the mold 2 as the casting table 14 rotates is located directly below the casting tube 32. The start and stop of the rotating motor 15 is controlled by the control system, so that different molds 2 can be cast in sequence and at intervals. By setting up a plurality of workstations, processes such as casting and cooling of the molten metal can be carried out simultaneously at different workstations, thereby improving production efficiency and flexibility. Furthermore, the mold 2 can be set to different specifications to meet processing requirements for different types of products.

The upper end of the control rod 41 at least partially extends upward from the cover body 34, and one end of the control rod 41 extending upward from the cover body 34 is connected to a lifting assembly connected to the control system; the vertical projections of the control rod 41 and the casting pipe 32 coincide, and a control cone 42 is coaxially connected to the bottom of the control rod 41, and the outer diameter of the control cone 42 gradually decreases from top to bottom (it has a large diameter end away from the casting pipe 32 and a small diameter end close to the casting pipe 32, and the inner diameter of the connection between the casting pipe 32 and the smelting pot 31 is between the large diameter end size and the small diameter end size), and the bottom of the control cone 42 is at least partially inserted into the casting pipe 32. The control system controls the lifting assembly to drive the control rod 41 to move vertically, so that the control cone 42 is inserted into the casting tube 32 to different depths (so that the casting tube 32 and the smelting pot 31 have different sizes of conductive cross-sections), thereby realizing precise control of the casting amount of the molten metal. After the predetermined amount of molten metal is cast, the control system controls the lifting assembly to drive the control rod 41 to move downward, so that the control cone completely blocks the connection between the casting tube 32 and the smelting pot 31, and the casting of the molten metal is stopped at this time.

Specifically, a fixing seat 47 is disposed at the upper end of the cover 34, and a plurality of vertically extending columns 45 are arranged at intervals on the fixing seat 47. The upper ends of the plurality of columns 45 are commonly connected to a horizontally disposed mounting seat 44. The lifting cylinder 43 is mounted on the mounting seat 44, and the first telescopic portion 431 is connected to the upper end of the control rod 41. The control system controls the elongation of the first telescopic portion 431 and then adjusts the depth of the control cone 42 inserted into the casting pipe 32, so as to achieve precise control of the amount of molten metal casting.

[0046] In some embodiments of the present application, Figure 8 , Fig. 9As shown, the stirring assembly 5 is also provided in the smelting pot 31, and the stirring assembly 5 includes a stirring shaft 51 which is coaxially sleeved outside the control rod 41 and in sliding contact with the outer peripheral wall of the control rod 41 (the control rod 41 and the stirring shaft 51 can slide relative to each other without affecting each other's work), the upper end of the stirring shaft 51 at least partially extends upward from the cover body 34, the end of the stirring shaft 51 extending upward from the cover body 34 is connected to the driving assembly, and the end of the stirring shaft 51 extending upward from the cover body 34 is rotatably mounted on the fixing seat 47 (the fixing seat 47 is provided with a A stirring seat 55 is horizontally arranged at the bottom of the stirring shaft 51 along its radial direction, and a plurality of stirring rods 54 extending vertically are arranged at intervals on the upper end surfaces of the stirring seats 55 on both sides of the axial direction of the stirring shaft 51. The stirring shaft 51 rotates to drive the stirring seat 55 and the plurality of stirring rods 54 to rotate, so as to stir the metal in a semi-molten state in the smelting pot 31.

A thermocouple 61 for detecting the temperature of the molten metal is provided at the bottom of the smelting chamber 3. The thermocouple 61 and the heating power supply are both connected to a control system. The control system controls the power of the heating power supply according to the temperature measured by the thermocouple 61, so that the molten metal in the smelting pot 31 is maintained within a set range, so as to avoid the intensified oxidation of the metal due to the excessively high temperature of the molten metal, the excessive fluidity and the generation of pores or shrinkage cavities; or the insufficient fluidity of the molten metal due to the excessively low temperature of the molten metal, which affects the integrity and density of the casting.
