When it is necessary to grind the protrusion or groove position of the plastic mold, the bottom of the grinding belt 15 can be placed in different planes under the action of the elastic member arranged at the bottom of the U-shaped frame 12, so that the grinding belt 15 can fit with the inner wall of the groove, and the driving part is controlled to start moving the grinding belt 15, thereby realizing the deburring of the plastic mold.
