Therefore, in recent years, with the emphasis on burr removal in various industries, deburring methods have emerged in an endless stream. For example, a burr processing device for the inner hole of a plastic shell with publication number CN211030906U includes a machine base, a lower mold installed on the machine base, a linear mold group for driving the lower mold to move horizontally, a rotating fixture installed on the upper end of the lower mold and used to position the plastic shell and rotatable to adjust the orientation of the plastic shell, a frame installed on the machine base, a lifting mechanism installed on the frame, a metal upper mold installed at the lower end of the lifting mechanism, and an electric box installed on the machine base. The metal upper mold is placed directly above the rotating fixture, and an L-shaped deburring embedding block is provided at the lower end of the metal upper mold. The embedding block can It is customized and replaced according to the shape inside the plastic shell, and a heating module is provided in the metal upper mold.
