Problems solved by technology

[0005] At present, the nozzles commonly used in the core shooting machine include straight-through nozzles, double-layer water-cooled nozzles and inner-coat air-cooled nozzles. When the inorganic sand is used for core shooting, the fluidity of the wet inorganic sand is very poor. When the nozzle shoots sand, the nozzle extends into the mold, and the front end of the nozzle contacts the high-temperature mold to heat the front end of the nozzle. At this time, the inorganic sand solidifies and blocks the nozzle after being heated; when the nozzle does not shoot sand, the nozzle The inorganic sand at the front port is exposed to the air. When the temperature of the outside air rises due to hot weather, the inorganic sand solidifies and crusts on the surface of the nozzle to block the nozzle, making it impossible to shoot sand.

Abstract

The invention relates to the technical field of molding sand casting and discloses a nozzle water cooling centre pneumatic device. The nozzle water cooling centre pneumatic device comprises supporting bases; lifting devices are arranged in the supporting bases; a water cooling base plate is connected to the working ends of the lifting devices; the middle of the water cooling base plate is provided with a water storing cavity; and a replaceable centre plate covers the water storing cavity and is provided with a plurality of sharp-head centres. Compared with the prior art, incrustive and cured sand at the front end of a nozzle is removed through the sharp-head centres, and the nozzle is kept smooth.

Description

technical field [0001] The invention relates to the technical field of molding sand casting. Background technique [0002] Organic sand is usually used in the field of sand casting, because organic sand has strong viscosity, which can improve the efficiency of sand casting, but organic sand will emit a lot of pollutants in the casting process. In order to reduce environmental pollution, some researchers Starting from the types of inorganic materials, inorganic sand has been developed. The use of inorganic sand for casting has also achieved better cores, and the use of inorganic sand has effectively reduced environmental pollution. Therefore, inorganic sand has been widely used in the field of sand casting. application. [0003] We all know that the use of organic sand to make cores is carried out in a high-temperature environment, while the requirements for inorganic sand are quite different. It requires that the entire application engineering process must be carried out in...
