Zunyi Tuote Casting And Forging Applied For A Centrifugal Impeller Processing Technology Patent To Solve The Defects Of The Impeller Casting Process
According to the financial industry news cnc machining factory on January 14, 2025, information from the State Intellectual Property Office shows that Zunyi Tote Casting and Forging Co., Ltd. has applied for a patent titled "A processing technology for centrifugal impellers", and the public account is CN A, application date is October 2024.
The patent abstract shows that this application discloses a processing technology for a centrifugal impeller in the field of casting technology, which includes the following steps: Sand core preparation: Prepare an impeller mold, put the sand core material into the mold and compact it, and wait for the sand core material to harden and form. Finally, the mold is taken out to obtain the sand core; sand mold production: Place the rectangular frame mold box on the upper mold and the lower mold, fill the sand core material into the mold box and compact it, and obtain the upper mold after hardening. Sand mold and lower sand mold; when making the lower sand mold, place a "U" shaped ceramic tube, and one end of the ceramic tube is connected to the bottom of the lower sand mold cavity. Mold clamping: Place the sand core into the cavity of the lower sand mold, place the upper sand mold, and assemble it with the sand mold; Casting: Inject molten steel into the gate, and the molten steel fills the casting cavity through the ceramic tube. After cooling, the impeller is obtained; sand mold removal: After the impeller is cooled, use tools to remove the remaining sand core material on the surface of the impeller. This solution solves the problems of wrinkles and low-cooling insulation defects in the impeller caused by the current impeller casting process.
