小件大批量机械化造型的砂箱采用铝合金材料制造,具有重量轻,工人造型时劳动强度低、操作方便,生产率高的优点,但是铝砂箱定位孔磨损较快,使用寿命不长。为此,我们采用了铸镶球铁定位套的办法,成功地解决了这一难题,使铝砂箱在大批量机械化、半机械化生产中得到了稳妥可靠的使用。 Small pieces of high-volume mechanized molding sand box made of aluminum alloy material, with light weight, low labor intensity when the workers shape, easy operation, high productivity advantages, but the aluminum sand box positioning hole wear faster, the service life is not long. For this reason, we adopted the method of cast iron ductile iron locating sleeve, which successfully solved the problem and made the aluminum sand box safe and reliable in large-scale mechanized and semi-mechanized production.
