The collecting device 11 includes a fixed A connecting plate 23 fixedly connected to the upper side of the first rotating shaft 10, two casting molds 24 fixedly connected to the upper side of the connecting plate 23, two springs 26 fixedly connected to the inner bottom wall of the casting mold 24, a movable plate 27 fixedly connected to the side of the spring 26 away from the casting mold 24, and a contact switch 25 installed on the inner bottom wall of the casting mold 24. The front end surface of the vacuum casting tank body 1 is inlaid with an observation window, and the observation window is tempered glass. The cooling pipe 14 is a spiral structure in the sleeve 13, and the two ends of the cooling pipe 14 respectively penetrate the sleeve 13 and extend to the outside.

[0026] The working principle of the above embodiment is:

[0027] The casting material is poured into the mixing tank 15, and the third driving motor 17 is started to drive the stirring rod 21 at the lower side of the second rotating shaft 18 to mix and stir the material. The heat energy generated by turning on the heating tube 20 is discharged from the filter holes on the surface of the fixed cylinder 19 to heat the material. According to the characteristics of the material itself, the pipeline can also be connected with one end of the cooling tube 14, and the coolant is injected into the cooling tube 14. With the spiral rotation, it moves downward in a spiral manner on the surface of the mixing tank 15 to quickly cool the inside, which can speed up the mixing of the casting material. The scraper 22 scrapes off the material attached to the inner wall of the mixing tank 15 when rotating, and then discharges it downward naturally. The first driving motor 3 starts the threaded rod 4 to drive the outer threaded sleeve 5 to collect the material. 1 moves to the lower side end of the mixing device 12, and the internal situation of the vacuum casting tank body 1 can be viewed through the observation window. The casting material naturally enters one of the casting molds 24. As the weight of the casting itself moves the movable plate 27 downward, the spring 26 is also compressed downward. When the weight of the casting material contacts the movable plate 27 with the contact switch 25, the second drive motor 7 is started to drive the first gear 8 to engage the second gear 9 to switch the casting mold 24 at the other end with the filled casting mold 24, thereby improving the casting operation. Finally, only the casting tank cover 2 is rotated to separate from the right side of the vacuum casting tank body 1, and the collecting device 11 is moved to the right end by the threaded rod 4 to be taken out.
