Abstract

The invention discloses a casting forming system with turnover directional cooling function and a using method thereof. The system comprises a sand mold, a molten metal conveying system, an external directional cooling system, a casting mold turnover system and a turnover power system. According to the casting forming system with the turnover directional cooling function, the internal defects of castings caused by contradictions, between a molten metal flowing state and a temperature field in a solidification process, generated during mold filling in traditional casting engineering can be reduced or eliminated, the material structure is refined, the performance of the castings is improved; and meanwhile, the production period is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of molding equipment, and in particular relates to a turning and directional cooling casting molding system and a using method thereof. Background technique [0002] The ultimate goal of the casting process is to produce high-quality castings without internal defects; there are two main factors affecting the internal quality of castings: one is the flow state of the molten metal during the filling process; the other is the temperature field of the molten metal during solidification distributed. During the filling process, if the flow of the molten metal is turbulent, the molten metal is likely to be involved in gas, which will not only cause the oxidation of the molten metal, produce micro oxides, which will become the core of casting cracking, and the gas involved in the molten metal will It will be precipitated during the solidification process, resulting in precipitated pore defects; if the molten metal flows in a...
