Abstract

The utility model relates to the technical field of casting, in particular to a hydraulic box turnover machine for V-method casting. Riding wheel groups are supported at the left end and the right end of the sand box; the left side riding wheel set is fixed to the folding support, and the folding support is arranged on the folding cylinder in a transmission mode and driven by the folding cylinder to rotate; the right side riding wheel set is fixed to a translation support which is arranged at the stroke end of a translation cylinder in a transmission mode and driven by the translation cylinder to translate. A box overturning cylinder which is coaxially and rotatably connected with the sand box is fixed on the translation bracket; the rotating center line of the box overturning cylinder and the rotating center line of the folding cylinder are spatially staggered and vertically arranged; and a box pressing mechanism for pressing a sand box is fixedly arranged on the folding bracket and the translation bracket. The hydraulic box turnover machine for V-method casting is prevented from being collided with a hoisted sand box, and is suitable for sand boxes of various sizes; the clamping structure prevents the sand box from axially deviating, and the operation is simple; the fixing part of the sand box is influenced by high-temperature casting sand.
