使用铸造方法,可以得到质量可靠、尺寸准确的另件,几乎不受形状复杂程度或尺寸大小的限制。铸造方法使设计师有较大的构思自由度,为制造高质量、低成本的产品提供有利条件。但在设计时,必须考虑铸造的工艺特性;否则,以上的优点,会由于设计不当而丧失。为此,本文提出一些基本守则,以供设计时参考。守则一:避免铸造应力 Using the casting method, it is possible to obtain a piece of reliable quality and accurate size, which is hardly limited by the shape complexity or size. Casting method allows designers a greater freedom of ideas, to create high-quality, low-cost products to provide favorable conditions. However, the design process, casting process characteristics must be considered; otherwise, the above advantages will be lost due to improper design. For this reason, this article presents some basic codes for reference at design time. Code one: to avoid casting stress
