抛砂机在铸造生产中已有6、7年的历史,它具有适应性强、生产效率高、能量消耗少、结构简单、重量轻等优点。为了更好地发挥抛砂机的效率,提高砂型质量和减轻劳动强度,我厂于1966年从国外引进了一台固定式液压抛砂机和一台钳口型翻台式起模机,又自行设计和制造了一台四工位转盘,组成抛砂机造型生产线,并于1974年投入生产。该线主要生产红岩- Sand throwing machine in the casting production has been 6-7 years of history, it has adaptability, high production efficiency, less energy consumption, simple structure, light weight and other advantages. In order to give full play to the efficiency of sand throwing machine to improve the sand quality and reduce labor intensity, I plant in 1966 from abroad to introduce a fixed hydraulic sand throwing machine and a jaw-type turn-table-type machine, and their own Design and manufacture of a four-station turntable, composed of sand throwing machine modeling production lines, and put into production in 1974. The main production line of Hongyan -
