A processing method of a die-casting die comprises the steps of preparing raw materials, mixing the raw materials, heating the raw materials and repeatedly heating the raw materials to finish casting.)

1. A processing method of a die-casting die is characterized by comprising the following steps:

a, preparing raw materials according to the following components by weight, 3% of carbon powder, 0.4% of nitrogen, 0.05% of tungsten, 2.6% of nickel, 3.3% of silicon powder, 1.7% of magnesium, 0.4% of manganese, 0.7% of boron, 0.2% of cobalt, 0.1% of molybdenum, 0.18% of bismuth, 0.12% of beryllium, 1.5% of titanium and 85.75% of iron;

b, mixing the raw materials, heating for 15-20min in an iron pot at the temperature of 75-90 ℃, pouring the mixed material into a hearth of a medium-frequency induction furnace, and heating;

c, heating the medium-frequency induction furnace to 380-430 ℃, keeping the temperature for 2-4h, turning off the power supply of the furnace, and then putting nitrogen with the temperature of 35-55 ℃ for cooling and continuously supplying gas for 15-25 min;

and d, heating the medium-frequency induction furnace to 980-1060 ℃ in a full load manner again to melt the raw materials, repeatedly stirring uniformly, introducing into a ladle, adding a nodulizer to perform a spheroidization reaction in the spheroidization ladle, removing waste residues on the surface, then pouring in a sand box at a pouring speed of 25-50kg/min, naturally cooling after the pouring is finished, and separating from the sand box to obtain the mold.

Technical Field

The invention discloses a processing method of a die-casting die, and belongs to the technical field of processing of precise die-casting dies.

Background
