近年来,一种通用性强的、高生产率的造型方法——气力冲击造型法得到了推广。这种方法是将压力为50～90公斤/厘米~2的压缩空气储存在固定的容积中,然后瞬时排出,以均匀的气流冲击型砂表面,使其紧实. 成型装置——冲击头,主要由储气室6(图1)和装在其内部的阀10组成.在储气室 In recent years, a versatile, high-productivity modeling method - the pneumatic impact modeling method has been promoted. In this method, compressed air at a pressure of 50 to 90 kg / cm 2 is stored in a fixed volume and then discharged instantaneously to impact the surface of the molding sand with a uniform flow to make it compact. Molding Machine - Impact Head, Main It consists of a gas reservoir 6 (Figure 1) and a valve 10 housed inside it
