压铸件通常是用金属模压铸而成的。设计压铸件的结构时,对其加工工艺性考虑不周,往往会提高模具的复杂性,增加加工成本,降低零件本身的质量。现通过若干实例来说明压铸件设计的加工工艺性的改进方法。附图(已略)针对每个实例示出了压铸件的两种不同的设计图形,具体说明如下: (1)通孔与不通孔孔的最小直径取决于金属材料的特性,而孔的最大深度则视孔径而定。对于锌铸件来说,建议孔的最小直径为0.040英寸;通孔的最大深度等于直径的8倍,而不通孔的最大深
Die casting is usually die-cast with a metal mold. Die-casting design of the structure, the processing of their ill-considered, often will increase the complexity of the mold, increase processing costs and reduce the quality of the parts themselves. Now through a number of examples to illustrate the die casting design process improvement methods. The drawings (omitted) show two different design drawings of the die-castings for each example as follows: (1) The minimum diameter of the through hole and the non-through hole depends on the characteristics of the metal material, and the maximum of the hole Depth depends on the aperture. For zinc castings, the minimum recommended hole diameter is 0.040 inches; the maximum depth of the through hole is equal to 8 times the diameter, whereas the maximum depth of the non-through hole
