The design and optimization of die runner is a very important link in the process of forging die manufacturing of construction machinery. Good design and optimization of die runner can improve the forming quality and production efficiency of forgings. The following are the general steps and precautions for mold runner design and optimization:
- Determine the shape and size of the forging: First of all, it is necessary to determine the shape and size of the construction machinery forging to be forged. This includes forging geometry, size and structural characteristics.
- Determine the location of the mold runner: Determine the location of the mold runner according to the shape and size of the forging. In general, the mold flow channel should be as close as possible to the maximum cross section of the forging to ensure the uniformity and fluidity of the hot metal during the filling process.
- Design the geometry of the mold flow path: the mold flow path is generally circular or rectangular cross section. In the design need to consider the mold flow channel size, length, Angle and other factors. Smaller sections and longer lengths can increase the resistance of the flow, which in turn increases the filling speed and filling pressure of the metal.
- Optimize the flow performance of the mold: The purpose of optimizing the flow path of the mold is to improve the filling speed and filling pressure, while reducing the metal gas inclusion and shrinkage holes and other defects. In the design, some technical means can be used to optimize the flow path, such as increasing the size of the filling head, adjusting the Angle and length of the mold flow path.
- Simulation simulation analysis: Analysis and optimization of mold flow performance by using fluid dynamics simulation software. Simulation can help engineers better understand the flow law of metal during the filling process and achieve the best filling effect by adjusting and optimizing the mold flow path.
In a word, the design and optimization of die runner is a complex and critical process of forging die manufacturing of construction machinery. Reasonable design and optimization of die runner can improve the forming quality and production efficiency of forgings, so as to meet the requirements of construction machinery forgings.
