The invention discloses a mold rapid
machining method based on a 3D printing mold core. The mold rapid
machining method based on the 3D printing mold core is characterized by comprising the followingsteps of S1, preparing needed raw materials; S2, designing a geometric structure of the mold core, and converting the geometric structure of the mold core into a format matched with a format in a
control equipment system; S3, using a 3D printing technology to print the mold core after S2 is finished; S4,
polishing and
grinding the mold core in S3 to a desired size and surface accuracy; S5, assembling the mold core in a mold base after S4 is finished; and S6, carrying out follow-up molding or
casting mold
batch production. By directly and rapidly performing 3D printing on the mold core,
polishing the surface of the mold core and fastening the mold core on the mold base, the follow-up molding or
casting mold
batch production of the mold core is carried out and realized. According to the moldrapid
machining method based on the 3D printing mold core, an
optimal design is realized, the efficiency or function of a terminal product is enhanced, a difficult problem of traditional machining technologies such as CNC during machining the complicated geometric structures is solved, the design is free, the manufacturing is rapid and green, and green and intelligent transformation and upgradingof the traditional mold industry are really realized.
