The runners on the runner plate need to be polished after a period of use to remove internal impurities and make the surface smooth. Most mold polishing machines used on the market are now used for polishing. In the existing technology, due to the different inner diameters of the runners of different injection molds, special polishing equipment is required, and the polishing equipment cannot be adjusted to adapt to different runner inner diameters.

[0003] For example, the authorized patent document with application number CN202322759018.7 discloses a closed impeller part internal flow channel polishing device, which includes an upper disc and a lower disc, which are connected up and down, and the connection between the upper disc and the lower disc cooperates to form a working chamber, which is a cavity for fixing the closed impeller and performing abrasive flow polishing on the closed impeller. Above the working chamber is a guide hole connected to the abrasive source, and below the working chamber is a diversion hole leading to the abrasive collector. This utility model can realize the working channel of high-pressure abrasive flow by connecting the upper and lower discs, and then realize the polishing of parts through the pressure impact of high-pressure abrasive flow. The position of the parts is fixed during polishing, the structure is simple and reliable, and the industrial feasibility is strong.
