一、问题的提出任何一种机械都是由简单到复杂,再从复杂到简单的转化过程,螺旋式向前发展。铸造机械方面,由手工造型进入机器造型后,造型主机从简单的震实台一直发展到高压、高效多工位造型机,并能组成多种多样的机械化、自动化造型生产线。我们不难看出在铸造机械发展的每一过程中,始终贯穿着有箱造型和脱箱造型交替发展,互相竞争的状态。现代的有箱造型已发展到工艺性能全面的多触头高压造型
First, the issue put forward Any kind of machinery is from simple to complex, and then from complex to simple transformation process, spiral forward. Casting machinery, the handmade shape into the shape of the machine, the shape of the host from a simple shock Taiwan has been developed to high pressure, high efficiency multi-station molding machine, and can form a wide range of mechanization, automation molding production line. It is not difficult for us to see that in every process of the development of foundry machinery, we always run through the state of alternating development and competition between the shapes of boxes and the shapes of boxes. Modern box molding has developed into a comprehensive multi-touch high-pressure process modeling
