铸造模具近几十年来发展很快,由于其生产周期短、成本低、寿命长等一系列优点,日益得到广泛应用。美国通用汽车公司90％以上采用铸造锻模,而曾用陶瓷型精密铸造法生产了重达七吨的冲压模,日本于1959年铸造出重3吨的冲压模,苏联汽车工业部门目前有十个工厂的十二个工段生产各种铸造模具。 Casting mold developed rapidly in recent decades, due to its short production cycle, low cost, long life and a series of advantages, are increasingly widely used. More than 90% of GM’s used forging die, while the use of ceramic precision casting method to produce a weight of seven tons of stamping dies, Japan in 1959 casting a heavy three tons of stamping dies, the Soviet automobile industry currently has ten Twelve sections of a factory produce a variety of foundry molds.
