The invention discloses polishing equipment for machining a hardware mold and having a clamping function. The polishing equipment comprises a pedestal; a supporting plate is placed above the pedestal;two symmetric supporting columns are fixedly connected to the upper surface of the pedestal; the upper surface of each supporting column is fixedly connected with the bottom surface of the supportingplate; the bottom surface of the supporting plate is fixedly connected with an electric push rod; and a telescopic end of the electric push rod is fixedly connected with a fixing plate. According tothe polishing equipment for machining the hardware mold and having the clamping function, the upper surface of the pedestal is provided with a fixing seat; the fixing seat is internally provided witha movable plate, a sliding chute and a slider; the to-be-polished hardware mold is placed at the upper surface of the fixing seat and is effectively clamped in a way of pushing clamping plates by utilizing the elastic force of strong springs, and thus occurrences such as inclination and drop of the hardware mold in a polishing process can be effectively prevented; and the polishing equipment is relatively good in clamping performance, can effectively improve the machining efficiency of the hardware mold and is more convenient to use.
