为适应生产发展的需要,七十年代初期我厂先后把两条老造型线改造成为射压造型自动线。其中,二线采用有箱造型工艺,砂箱尺寸为600×400×170/170毫米,生产小型铸件;三线则是脱箱造型,砂型尺寸为1050×650×280/200毫米,生产中型铸件。这两条射压造型自动线,由于其自动化程度高、操作简单、生产率高、铸件质量好等优点,而深为广大职工所喜爱。但是,与原来震压造型机相比较,自动线设备较为复杂,因此设备维修工作繁重,特别是三线。数年来,我们在实践中通
In order to meet the needs of the development of production, in the early seventies, our factory transformed the two old molding lines into automatic molding lines. Among them, the second line with a box molding process, sand box size 600 × 400 × 170/170 mm, the production of small castings; third line is off the box shape, sand size 1050 × 650 × 280/200 mm, the production of medium-sized castings. The two automatic injection molding lines, because of its high degree of automation, simple operation, high productivity, good casting quality advantages, but deep for the majority of workers love. However, compared with the original shock molding machine, automatic line equipment is more complex, so heavy equipment maintenance work, especially the third line. Over the years, we passed in practice
