Description

Technical Field

[0001] This utility model belongs to the field of shaft parts manufacturing technology, and in particular relates to a precision forming mold for continuous casting of large shaft forgings. Background Technology

[0002] Large shaft forgings are continuous casting billets, which are preliminary blanks used to produce long metal materials such as shafts. They are usually formed by cooling molten metal through continuous casting. These billets are often used to manufacture various large parts that require high mechanical properties, such as shafts and pipes. During the forming process, continuous casting billets are injection molded using forming molds.

[0003] There are two common cooling methods used in the injection molding of continuous casting billets: water cooling and air cooling. Water cooling carries the heat from the mold, and if it needs to be reused, it needs to be cooled. Since the water flowing back into the water tank is recycled and reused, the cooling time is short, resulting in a small temperature difference between the water and the mold and a poor cooling effect. Air cooling relies on a motor to drive the fan, but the air is not cooled, which reduces the cooling efficiency and affects the production of continuous casting billets.

[0004] To address these issues, we provide precision forming dies for large shaft forgings and continuous casting billets. Utility Model Content
