Introduce of cold core shooting machine 1. Application: 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.Technical parameters
