泥型的造型方法和一般砂型相同,但为了使鑄型完整和操作方便,在不妨碍鑄件补縮的前提下,浇冒口数量应該較少,并且最好能放在泥芯内。較高的鑄件可用多层砂箱造型,較复杂的鑄件最好用劈型造型法,把整个鑄型分成几块。在一般情况下最好采用两半型,鑄件在每半型中不要太深,同时尽量使鑄件的主要的加工面在鑄型的底面。例如車床床身的鑄造采用水平造型、侧立浇注,浇注系統在分型面上这样比較合理。
Mud shape modeling method and the same general sand, but in order to make the mold complete and easy to operate, without prejudice to the casting of the premise, the number of runners should be less, and the best can be placed in the mud core. The higher the casting can be multi-layer sand box modeling, the more complex casting is best to use split-type modeling method, the entire mold is divided into several pieces. Under normal circumstances, it is best to use two halves, the casting should not be too deep in each half, while trying to make the casting of the main processing surface in the bottom of the mold. For example, lathe bed casting using horizontal shape, side vertical casting, casting system in the parting surface is more reasonable.
