The bakelite mold that comes out of this way can be used to die-cast a beautiful die-casting part.), processed under stable discharge conditions; after compression machining of die casting mold, stable relaxation treatment; reasonable setting on die casting mold Process holes, grooves; fully eliminate the re-solidified layer, so as to be used in a sound state; using the vector translation principle, the part of the internal stress that has been concentrated in the cutting-out of the die-casting mold is arbitrarily diverted and discharged. Prevent overheating and decarburization during heat treatment of the die-casting mold, and fully temper the Guangdong aluminum die-casting mold to reduce or eliminate the residual stress; in order to completely eliminate the internal stress generated during the quenching of the die-casting mold, high-temperature tempering must be performed, so Steel grades capable of withstanding high temperature tempering (such as Crl2 type, ASP-23, high speed steel, etc.. In this way, defects such as deformation or cracks often occur during the electrical discharge machining of the die-casting mold.Aluminum die casting process Aluminum die-casting process in the production of aluminum die-casting molds, die-casting molds using electrical discharge Injection mould machining (electric pulse and wire cutting) is an increasingly common processing method, but with the widespread application of die-casting die discharge machining, caused by die-casting die The defects have also increased accordingly. Therefore, the use of electric discharge die-casting molds must fully understand the impact of electrical discharge machining on die-casting mold materials, and take appropriate precautions in advance. Since the electric discharge machining of the Huangjiang aluminum die-casting mold is a processing method for melting the surface of the die-casting mold by means of the high temperature generated by the discharge, a white electric discharge machining metamorphic layer is formed on the surface of the die-casting mold, and the die-casting mold is generated and a tensile stress of about 800 MPa is generated
