用木材来制造泥芯盒,不仅需要大量的木材,而且要化很多工时,因此在单件生产、泥芯需要数量不多的情况下,一些简单的泥芯都采用刮板来制造,这虽然给木模制造上节省木材,缩短工时,可是,在造型上就比较复杂了,在最近我们试用水玻璃砂来制成芯盒,得到初步成功。 Masonry boxes made of wood require not only a large amount of wood but also many man hours, so that in the case of a single piece of material, the number of mud cores needed is small, some simple mud cores are produced using a squeegee, although To save on timber manufacturing wood, shorten working hours, however, the shape is more complicated, and in the recent trial of sodium silicate we made the core box, the initial success.
