1、浇铸金属模型方法
1. Method of casting metal model
在制造形状复杂和不规则曲面的金属模型时,假如数量较多,并且要求可以精确互换的话,都可以采用石膏模型的方法来制造。用石膏模型做金属模型与用木料作模型不一样,它只能用“复杂模型”来制造,即将石膏浆灌注在一个实体模型上,得出一个与 实践模型彻底符合的不和的模具,然后再在石膏模型中浇铸金属模型。下面举一个作犁铧铁模的比如来说明制造石膏模的工程程序。
When manufacturing metal models with complex shape and irregular curved surface, if there are a large number and they are required to be accurately interchangeable, they can be manufactured by gypsum model. The metal model made of gypsum model is different from that made of wood. It can only be made of "complex model", that is, the gypsum slurry is poured on a solid model to obtain a discordant mold completely consistent with the practical model, and then the metal mold is cast in the gypsum model. The following is an example of an iron mold for a plowshare to illustrate the engineering procedure for manufacturing a gypsum mold.
2、机加工金属模型
2. Machined metal model
依据机械模型的外观制造出三维数据模型，依据结构设计零部件，进行机器三维雕琢，这种方法适用于数量少，要求精度的机械模型，由于这种制造方法比较昂贵，一般不采用这种方法。
The three-dimensional data model is manufactured according to the appearance of the mechanical model, and the parts are designed according to the structure for three-dimensional carving of the machine. This method is applicable to the mechanical model with small quantity and precision requirements. This method is generally not used because it is expensive.
3、模具加工法
3. Die processing method
依据机械模型的结构，设计制造出金属模型的模具，用压铸机压铸出金属模型，这种制造方法适用于批量制造，批量制造成本低，速度快等优点
According to the structure of mechanical model, the mold of metal model is designed and manufactured, and the metal model is cast by die casting machine. This manufacturing method is suitable for batch manufacturing, with the advantages of low cost and high speed
