Cores and method for connecting cores by charging connecting sand into them |
摘要 |
A method for connecting a plurality of cores in an assembly through adjacent surfaces of the adjacent cores is disclosed. This method includes the steps of: (a) forming a plurality of cavities between adjacent surfaces of two adjacent cores, the plurality of cavities being horizontally aligned and spaced apart along the adjacent surfaces; (b) arranging the plurality of cores in a row; (c) filling a hopper nozzle with a predetermined amount of connecting sand; (d) indexing the hopper nozzle above one of the cavities; (e) supplying compressed air into the hopper nozzle that contains the connecting sand, thereby projecting and charging the mass of the connecting sand from the hopper nozzle into the cavity; and (f) repeating steps (c), (d), and (e). <IMAGE> |
