During use, the raw materials to be poured are poured into the mixing drum 25 and stirred through the stirring rod 26, and the interior of the box body 1 is vacuumed. The flat plate 31 is moved downward so that the feed pipe 34 is inserted into the injection port of a mold 44. At this time, the mixing mechanism 2 is rotated so that the stirred raw materials are poured into the feed trough 33 on the flat plate 31. At this time, the raw materials are injected into the mold 44 through the feed pipe 34. After the casting of one mold 44 is completed, the feed pipe 34 is moved upward, and the base 41 is rotated to rotate the other mold 44 to the bottom of the feed pipe 34. The feed pipe 34 is then connected to the mold 44 for casting, and so on. The multiple molds 44 on the base 41 are cast one by one by rotation, so that the casting of multiple molds 44 can be automatically completed at one time, effectively improving the casting efficiency of the vacuum casting device.

[0028] In this embodiment, if Figure 2 、 Figure 3 and Figure 4 As shown, a rectangular frame 21 is installed on the mixing mechanism 2, and rotating shafts 23 are symmetrically connected to the two side surfaces of the rectangular frame 21. One end of one rotating shaft 23 is connected to a second motor 24, and the second motor 24 is installed inside the shell of the box body 1. When the second motor 24 rotates, it can drive the rectangular frame 21 to rotate counterclockwise, so that the raw materials in the mixing drum 25 can be poured into the discharge trough 33 after the rectangular frame 21 rotates.

[0029] In this embodiment, if Figure 2 and Figure 3 As shown, a motor 22 is installed on the top of the rectangular frame 21, and a stirring rod 26 is installed on the inner top of the rectangular frame 21. The motor 22 drives the stirring rod 26 to rotate. A stirring drum 25 is clamped on the inner bottom of the rectangular frame 21. The stirring rod 26 is located on the inner side of the stirring drum 25. Therefore, after the raw materials are poured into the mixing drum 25, they can be stirred evenly by the stirring rod 26.

[0030] In this embodiment, if Figure 2 and Figure 4As shown, electric push rods 32 are installed at the four corners of the top of the flat plate 31, and one end of the electric push rods 32 is fixed on the inner wall of the box body 1. Therefore, the flat plate 31 can move vertically up and down under the drive of the electric push rods 32, making it convenient to insert and remove the discharge pipe 34 from the pouring port of the mold 44.

[0031] In this embodiment, if Figure 4 and Figure 5 As shown, a stepper motor 42 is embedded in the top center of the base 41. The body of the stepper motor 42 is located in the shell of the box body 1 and the rotating shaft is connected to the base 41. A plurality of feeding troughs 43 are evenly opened on the top of the base 41, and the molds 44 are respectively installed in each feeding trough 43. Each time the stepper motor 42 rotates once, the pouring port of a mold 44 is located directly below the discharge pipe 34. Therefore, after completing the pouring of one mold 44, the stepper motor 42 is rotated once to pour another mold in the same way. This is repeated to complete the pouring operation of all the molds 44 on the base 41.

[0032] Working principle: When the vacuum pouring device is in use, the raw materials to be poured are first poured into the mixing drum 25 and stirred by the stirring rod 26, and the interior of the box body 1 is vacuumed. At this time, the electric push rod 32 drives the flat plate 31 to move vertically downward, so that the bottom of the discharge pipe 34 is inserted into the pouring port at the top of a mold 44, and then the motor 24 rotates to drive the rectangular frame 21 to rotate counterclockwise, and the raw materials in the mixing drum 25 are poured into the discharge trough 33 after the rectangular frame 21 rotates and enters the discharge pipe 34. At this time, the raw materials are poured into the mold 44 through the discharge pipe 34. After completing the pouring of one mold 44, the stepping motor 42 is rotated once to pour another mold in the same way. This is repeated to complete the pouring operation of all molds 44 on the base 41, so that the pouring of multiple molds 44 can be automatically completed at one time, effectively improving the pouring efficiency of the vacuum pouring device.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
