After the left and right core boxes are closed, the sand is filled from the opening (top core head part) of the top, and after solidification, the core box is opened to obtain the whole sand core standing on the bottom plate. However, for some shell castings, the top is not designed with a core head or the core head is small due to the closed structure or the small opening at the top, and it is difficult to fill sand from the core head position of the top of the core box during core manufacturing. In this case, the core box needs to be inverted, and the sand is filled from the core head opening position of the bottom of the core box. However, such core boxes usually only have left and right core boxes without a bottom plate, and after the sand core is solidified, the core box is directly opened, and the sand core cannot stand and will fall and damage the sand core. After the sand core is taken out, it needs to be turned over before use. Such sand core turning is usually difficult and easy to damage the sand core. For this situation, small core boxes are usually manually turned over, and large core boxes are usually pulled by a crane, the core box is turned over, the core box is opened, and the whole sand core standing on the bottom plate is taken out. The core box is turned over by the crane, which does not meet the safety use specification of the crane, and also causes damage to the core box and the ground to a certain extent.
