Automatic Cold Box Sand Core Shooting Machine/Sand Core Shooter Plant

Product Description

 Cold core box is a kind of high efficiency core-making technology. Compared with hot core box and shell core, cold core box has the advantages of high efficiency, energy saving and good working conditions. It has been widely used in casting production.

The core quality and speed of the cold core box method are closely related to the ambient temperature, humidity, air temperature, air pressure and air blowing time. To ensure the quality of the sand core, the following measures should be taken: when the temperature of raw sand is on the high side, the storage time of sand mixture should be shortened appropriately;When the temperature of the original sand is low, the sand temperature regulator should be opened to increase the sand temperature appropriately to ensure the hardening speed of the sand core.For large sand cores, the blowing pressure and blowing time can be appropriately increased to ensure the hard permeability.Different requirements of blowing air temperature for hard gas are different, the SO2 room temperature is a gas without heating, and the room temperature of triethylamine and methyl formate is a liquid, which is easy to condensate in the pipeline in winter, the blowing pipe shall take appropriate heating and insulation measures to ensure the content of triethylamine (methyl formate) in the hard gas is relatively stable.Triethylamine method and modified silicate sand blowing carbon dioxide/compressed gas combined blowing method are very sensitive to air humidity, and compressed air needs to be dehumidified.
