Efficient multi-layer overlapping pouring device for casting parts

The invention relates to the field of casting and provides an efficient multi-layer overlapping pouring device for casting parts. The device is applicable to casting of laminating sand molds, resin sand molds, water glass sand molds and the like. The overlapping pouring device is characterized in that a bottom sand mould is arranged on a bottom plate, the upper side of the bottom sand mould is provided with a main sand mould, a loop, a casting part and a water inlet, the main sand mould, the loop, the casting part and the water inlet form pouring single layers, the upper layer of the device isprovided with a cover plate, a pouring cup and a connection pouring gate, an air output hole is formed between the cover plate and the pouring cup, and the pouring single layers are overlapped to form overlapping pouring. By the adoption of the technical scheme, the casting efficiency is improved, the pouring time is shortened, the feeding effect is good, the quality of the casting parts is improved, and the production c
