A second slide 10 is movably mounted on the second lead screw 8 and the second guide rod 9. The mounting frame 11 is fixedly connected to the mounting frame 11. The second slide 10 and the second lead screw 8 form a helical pair. The stirring frame 13 is equipped with an electric heating wire for heating the material.

[0024] A collection component is provided between the material cylinder 2 and the pouring section 5 for mixing and concentrating materials. The collection component includes two docking frames 16 slidably mounted on the base 1. A centralized mounting plate 18 is connected to the docking frames 16, and a centralized cylinder 17 is rotatably mounted on the centralized mounting plate 18. The two centralized cylinders 17 are docked to form a closed cavity for mixing and concentrating materials. One end of the closed cavity is connected to the collection section 601, and the other end of the closed cavity is connected to the pouring section 5. The collection component includes a motor 3 14 and a lead screw 3 15 mounted on the base 1. Motor 3 14 is used to drive lead screw 3 15; docking frame 16 and lead screw 3 15 form a helical pair; a rotating shaft 20 is rotatably mounted on the centralized mounting plate 18, and gears 21 are respectively provided at both ends of the rotating shaft 20.

The materials are mixed and concentrated in the closed cavity. The motor 19 works, and under the gear transmission, the collection cylinder 17 rotates, and the materials are mixed inside the closed cavity. Furthermore, the centralized mixing frame 22 located inside the closed cavity stirs the materials. Finally, the materials are transferred to the casting section 5 for casting.
