铸造车间以湿砂造型机为中心的自动化发展起来了,而能用于多品种小批量生产的自硬砂造型自动化却几乎处于停顿状态。这是由于有机铸型的普及还是近几年的事,而造型作业几乎还都是手工把型砂加入砂箱进行造型的。从手工造型的繁重劳动和环境卫生的观点来看,有必要采用自动化造型,但是一直没有研制出合适的造型机。这次发表的吸压造型法,是使用速硬性的气体硬化有机树脂,利用真空力在短时间内完成造型的方法。采用该方法,使得采用木模自 Foundry shop to wet sand molding machine as the center of automation developed, and can be used for many varieties of small batch production of self-hardening sand modeling automation is almost at a standstill. This is due to the popularization of organic molds or in recent years, while the modeling operations are almost always done manually by adding sand into the sandbox for modeling. From the point of view of manual labor and sanitation, it is necessary to use automatic molding, but no suitable molding machine has been developed. The press-suing method published this time is a method that uses a hardened gas-hardened organic resin and uses a vacuum force to complete the molding in a short period of time. Using this method, the use of wood mold since
