二、低压铸造用金属型随着低压铸造工艺的广泛应用,金属型低 压铸造也日益增加,而铸型设计对保证低压铸造工艺的成功起着重要的作用。本节对铸型设计要点作扼要的介绍。铸件的顺序凝固和铸型的排气是本工艺金属型设计时需要考虑的最重要因素。特别是铸型的排气是完全不同于重力浇注的金属型和压力铸造的铸型。浇注的铸件成功与否主要是取决于对上述两因素的考虑是否合适。
Second, the low-pressure casting metal With the low-pressure casting process is widely used, metal-based low-pressure casting is also increasing, while the mold design to ensure the success of low-pressure casting process plays an important role. This section gives a brief introduction to the design points of the mold. The order of casting solidification and mold exhaust is the most important factor to consider when designing the metal-based process. In particular, the exhaust of the mold is completely different from gravity-poured metal and pressure-cast molds. Casting casting success or not depends mainly on the above two factors considered appropriate.
