Description

Technical Field

[0001] The utility model relates to the technical field of metal silicon production, in particular to a forming die for metal silicon production. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by methods such as injection molding, blow molding, extrusion, die-casting or forging, smelting, and stamping. In the existing production of metallic silicon, the raw materials of metallic silicon need to be heated to a liquid state and then separated. Due to the high melting point of metallic silicon, metallic silicon will generally only be converted into a relatively pure state at a high temperature of more than 1000 degrees. After the liquid metallic silicon is separated, it needs to be cooled to solid metallic silicon. The cooling method of liquid metallic silicon is generally a natural air cooling mode. At present, the cooling process of metallic silicon on the market is generally carried out directly on the molding mold.

[0003] The publication (announcement) number is CN217570757U, which discloses a cooling mold for metal silicon production, including a mold body made of cast iron, a cooling cavity is arranged on the upper surface of the mold body, and end openings are arranged at both ends of the cooling cavity, the depth of the cooling cavity is at least one-third of the thickness of the mold body, and the depth of the cooling cavity is at most one-half of the thickness of the mold body, the end opening is located on the side end surface of the mold body, and a lifting part is arranged in the area of ​​the mold body different from the end opening. This application has the following expected technical effects: simple structure, relatively low production cost, suitable for market promotion and application.

[0004] Although the above scheme improves the natural cooling effect of metallic silicon on the mold body, it is difficult to uniformly lock and fix multiple mold bodies after they are simply stacked at intervals. The stacked mold bodies are prone to tipping over, and leakage of high-temperature liquid silicon will cause safety hazards. In addition, the cooling and molding operations in the production process of metallic silicon are inefficient if only natural cooling is used. For this reason, we propose a molding mold for metallic silicon production. Utility Model Content

[0005] The main purpose of the utility model is to provide a forming mold for metal silicon production, which solves the problem that a plurality of mold bodies are difficult to be uniformly locked and fixed after being merely stacked at intervals by means of a positioning unit.
