从目前国内外铸造生产的发展趋势可知,提高铸造生产的机械化,自动化水平是提高劳动生产率、降低生产成本、改善铸件质量的唯一途径。大批大量生产性质的铸造车间自六十年代以来压实紧实法的高压造型有了十分迅速的发展,但是对于单件,小批生产性质的铸造车间采用何种类型的造型机并如何发挥它的效率是摆在铸造工作者面前的关键课题,据本人的了解所知:目前国内大多数单件,小批生产性质的铸造车间均未能很好地解决这一问题,流态自硬砂的出现曾为这样类型的铸造车间减轻体力劳动,实现
From the current development trend of foundry production at home and abroad, we can see that improving mechanization and automation of foundry production is the only way to improve labor productivity, reduce production cost and improve casting quality. There has been a very rapid development of the high-pressure molding of a large number of mass-produced foundry shops that have been compacting and compacting methods since the 1960s. However, what type of molding machines are used in a single-piece, small-batch foundry and how to use it Efficiency is a key issue for casting workers. According to my understanding, at present, most of the foundry workshops in China with single pieces and small batches have not solved this problem satisfactorily. The flow of self-hardening sand The advent of this type of foundry has lightened physical labor to achieve
