Abstract

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 cost is reduced.

Description

technical field [0001] The invention relates to the field of casting, and relates to a high-efficiency overlapping pouring device for multi-layer castings. This device is suitable for the casting of coated sand mold, resin sand mold, sodium silicate sand mold and other types. Background technique [0002] The conventional pouring process generally adopts single-layer pouring, which has the disadvantages of low efficiency, large floor area, low yield, and waste of resources; moreover, the size of the casting is not accurate, the hardness of the casting material is unstable, the material density is insufficient, and the single-layer feeding pressure Insufficient and too fast solidification time, resulting in insufficient feeding and prone to loosening and other problems. Contents of the invention [0003] The purpose of the present invention is to provide a kind of can guarantee product quality, and casting process is simple, can be designed as each layer single piece or ea...
