With the progress of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles and home appliances, die-casting technology has achieved extremely rapid development. In the process of discharging materials from the die-casting machine, some metal liquid will produce an oxide film when it comes into contact with the air, causing the metal liquid to remain on the surface of the hopper along with the oxide film.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] See also Figure 1-Figure 4 The utility model provides a technical solution: a material discharge channel of a die-casting machine, comprising a driving motor 1 and a supporting connecting column 2 supporting the driving motor 1, the supporting connecting column 2 is installed on a device bottom plate 3, a material discharge hopper 7 is installed on the supporting connecting column 2 through a connecting fixing ring 6, and the driving motor 1 is connected to a residual scraping rod 5 through a transmission rod 4.
[0018] The lower hopper 7 consists of two parts, the upper part is a circular wall-like structure, and the lower part is a surrounding wall-like structure of a truncated cone. The lower end face of the lower hopper 7 has a discharge port in the middle that is aligned with the material injection tank 8 arranged below. The interfaces of the two parts can prevent material splashing and allow the material to flow smoothly into the material injection tank 8.
[0019] The material injection tank 8 is a circular columnar structure with an elliptical notch set on the upward side, facing the discharge port of the lower hopper 7. The end face of one side of the material injection tank 8 is connected to the mold fixing plate 11, and the right end face of the material injection tank 8 is connected to the piston push rod 9.
[0020] The end face of one side of the piston push rod 9 extends to the interior of the material injection tank 8, and is provided with a convex structure of a frustum on the end face, and the diameter of the protrusion structure fits the inner diameter of the material injection tank 8. The fitting structure can provide sufficient pressure when injecting the material.
[0021] The surface of the mold fixing plate 11 is connected to the die-casting mold 12. The mold fixing plate 11 and the die-casting mold 12 are symmetrically connected in two groups. At the position where the mold fixing plate 11 is connected to the material injection tank 8, there is an injection hole for receiving the material. The injection hole passes through the mold fixing plate 11 and is connected to the die-casting mold 12. The cylinder 10 is connected to one side end face of the piston push rod 9.
[0022] The outer surface of the residual scraper rod 5 has a certain curvature to fit the inner wall surface of the lower hopper 7, and the overall length extends from the lower feeding port to the discharge port. The inner surface of the residual scraper rod 5 also has a curvature, and the inner wall and the outer wall intersect to form a pointed "shovel"-like structure. The curvature of the inner side of the residual scraper rod 5 can remove the residual material while allowing the material to slide out along the inner side of the arc.
[0023] When the utility model is in use, the molten metal is poured into the material feeding hopper 7, and the material enters the material injection tank 8 along the material hopper 7. The driving motor 1 starts to operate, and the residue scraping rod 5 starts to make a circular motion along the inner wall of the lower hopper 7 to scrape the residue on the inner wall of the lower hopper 7. As the cylinder 10 operates, the piston push rod 9 is pushed, and the piston push rod 9 pushes the metal liquid in the material injection tank 9 into the die-casting mold 12 along the injection hole on the mold fixing plate 11 at a certain pressure.
