A mechanism and a method for automatically exchanging polishing tools in a mold polishing device. A polishing tool, which is mounted on a spindle of an arm of a robot, is pressed onto and displaced along the work surface to polish the same. A T-shaped holder is provided at a leading end portion of the spindle, and the polishing tool is provided with a pair of notches that allow a pair of latch pins to be press-fitted thereinto and forcibly withdrawn therefrom. A tool stand and a tool removal stand are provided in the vicinity of the mold setting area. A plurality of polishing tools are disposed on the tool stand. A horizontal slot of a narrow width that allows passage of the latch pins is formed in the tool removal stand. The arm, together with the holder, is raised such that the latch pins pass upward through the slot of the tool removal stand. The polishing tool is thereby removed from the holder. Thereafter, the arm and the holder are lowered from above towards another polishing tool so as to mount the polishing tool on the holder. |
