[0002] The aluminum alloy sacrificial anode casting device is a device specially used for producing aluminum alloy sacrificial anodes. This device is mainly used to inject molten aluminum alloy into a mold, and form the required sacrificial anode shape after cooling and solidification. In the existing technology, a pouring gate is provided at the upper end of the mold, and a smelting furnace is provided on the right side of the mold. The discharge port of the smelting furnace pouring pipe corresponds to the pouring gate, so that the sacrificial anode can be cast, and a filter is provided at the pouring gate to filter impurities in the pouring liquid. However, after a long period of filtration, the impurities in the pouring liquid will adhere to the filter screen, and the impurities on the filter screen cannot be cleaned in time, which may cause the filter screen to be blocked, requiring staff to frequently disassemble and clean the filter screen, increasing maintenance costs and maintenance frequency.

[0003] For example, the utility model with announcement number CN201728357U discloses a magnesium alloy sacrificial anode casting system. In the technical solution of this patent, a casting mold is obliquely arranged on a support frame, a pouring gate is arranged obliquely above the casting mold, a smelting furnace is arranged at the right end of the support frame, and a pouring pipe corresponding to the pouring gate is arranged at the right end of the smelting furnace to cast the sacrificial anode, and a filter is arranged at the pouring gate for filtering the casting liquid. However, in this method, impurities in the casting liquid will remain on the filter screen, which may cause the filter screen to be blocked, requiring staff to frequently disassemble and clean the filter screen, reducing work efficiency.

By setting the filter screen, solid impurities in the molten metal can be effectively intercepted to prevent these impurities from entering the mold, thereby reducing defects inside and on the surface of the casting. Baffles are provided at the front and rear ends of the pouring gate, and a cleaning part for cleaning the filter screen is provided at the left end of the pouring gate. The cleaning part includes a mounting plate provided at the upper ends of the two baffles, a telescopic push rod is provided at the left end of the mounting plate, and a scraper plate is provided at the output end of the telescopic push rod. The front and rear side walls of the scraper plate are in conflict with the baffle, and the lower side wall is in conflict with the filter screen.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0009] Firstly, by setting up a cleaning part, the scraper plate can be pushed by the telescopic push rod to scrape off the impurities on the filter screen, ensuring that the impurities on the filter screen are removed in time, avoiding the problem of decreased filtration efficiency or blockage caused by the accumulation of impurities.

[0010] Secondly, a filter is installed at the pouring gate. By installing the filter, solid impurities in the molten metal can be effectively intercepted to prevent these impurities from entering the mold, thereby reducing defects inside and on the surface of the casting.

[0011] Third, baffles are provided at both ends of the pouring port, which can enclose the front and rear ends of the pouring port to prevent the pouring liquid from splashing from the front and rear ends of the filter.

[0012] Fourthly, by setting up a pouring pump, the pouring pump can accurately control the flow rate of the pouring liquid during the pouring process, ensuring the stability and controllability of the pouring process. BRIEF DESCRIPTION OF THE DRAWINGS

Baffles 202 are provided at both the front and rear ends of the pouring port, and the baffles 202 can be used to enclose the front and rear ends of the pouring port to prevent the pouring liquid from splashing from the front and rear ends of the filter screen 201. A cleaning piece for cleaning the filter screen 201 is provided at the left end of the pouring port, and the cleaning piece includes an installation piece provided at the upper ends of the two baffles 202.
