Box turnover machine for casting line

Abstract

The invention relates to a box turnover machine for a casting line, and belongs to the technical field of lost foam casting, the box turnover machine comprises a base, a first turnover frame and a second turnover frame, the first turnover frame and the second turnover frame are arranged on the base, the first turnover frame is rotatably connected with the base, the second turnover frame is rotatably connected with the first turnover frame, a first telescopic rod is arranged between the first turnover frame and the base, and a second telescopic rod is arranged between the second turnover frame and the base. A first telescopic rod is arranged between the first overturning frame and the second overturning frame and used for overturning the first overturning frame and the second overturning frame from a first position to a second position, a second telescopic rod is arranged between the second overturning frame and the first overturning frame and used for overturning the second overturning frame from the second position to a third position, and a box hopper is arranged on the second overturning frame. According to the device, the box hopper is turned over twice at a small angle, so that the stability of the turning action is improved, a casting in the box hopper is prevented from moving at a large throwing angle, and the possibility that the casting is damaged is reduced. In addition, the stroke of the first telescopic rod and the stroke of the second telescopic rod are smaller, and optimization of the space layout of the box turnover machine is facilitated.
