Description

Technical Field

[0001] The utility model relates to the technical field of aluminum rod melting and casting molds, in particular to an aluminum rod processing melting and casting mold. Background Art

[0002] Aluminum is a light metal whose compounds are widely distributed in nature. The resources of aluminum in the earth's crust are about 40 to 50 billion tons, ranking third after oxygen and silicon. It is the largest category of metals. Aluminum rod is a kind of aluminum product. The smelting and casting of aluminum rod includes melting, purification, impurity removal, degassing, slag removal and casting process. According to the different metal elements contained in the aluminum rod, aluminum rod can be roughly divided into 8 categories. Before processing, aluminum rod is cast through corresponding casting molds.

[0003] Chinese patent announcement number CN217044530U discloses a mold for making aluminum bars from purified alloy aluminum water. A push plate, a connecting rod, a connecting plate, a slide groove and a slider are provided, and a hydraulic cylinder is started. The hydraulic cylinder drives the connecting plate and the connecting rod to rise. The rising connecting rod can enable the push plate to push out the aluminum bar inside the mold cavity. Pushing the aluminum bar out of the mold cavity can facilitate the demoulding of the aluminum bar, thereby improving the demoulding efficiency. When the hydraulic cylinder drives the connecting plate to rise and fall, the slider will slide inside the slide groove. The sliding of the slider inside the slide groove can limit the connecting plate and improve the stability of the push plate and the connecting rod, thereby solving the problem of inconvenience in demoulding the aluminum bar and poor working efficiency.

[0004] However, compared with the prior art and comparative documents, the existing aluminum rod casting mold is used by feeding molten aluminum water into the mold and then cooling it into shape through water cooling. During the feeding process, the aluminum water contains a large number of bubbles, which cannot be effectively discharged, resulting in bubbles in the formed aluminum rod, thereby reducing the quality of the aluminum rod.
