Description

Technical Field

[0001] The utility model relates to the technical field of case closing machines, in particular to a case closing machine for castings. Background Art

[0002] In the modern casting production process, in order to improve the efficiency of casting and meet the requirements of modern production, most castings currently use automated molding lines for production. In the production process of the automated molding line, after the sand box in the molding section is completed, it needs to be transferred to the pouring section. Before being transferred to the pouring section, the box closing process must be completed first, and then the closed sand box is pushed into the pouring section.

[0003] In the prior art, when closing the sand box, a closing machine is usually used to clamp the upper box body on the conveyor belt and raise it to a certain height, and then the upper box body and the lower box body are aligned and pressed together by a lifting device and a moving device to complete the closing of the sand box. However, the conveyor belt of the existing closing machine does not have a limiting device. During the transportation of the sand box, it is very easy to deviate, thereby affecting the accuracy of closing the box. In addition, the clamping device of the existing closing machine cannot be turned over. When the upper box body on the conveyor belt is placed in the wrong direction, the closing machine will continue to close the upper box body with the wrong direction with the lower box body, resulting in a closing error, which is very likely to cause damage to the sand box.
