Automatic grinding device for core rod sprue

Abstract

The automatic grinding device comprises a base, a display screen is arranged on the front face of the base, a support is fixedly connected to the base, a second through hole is formed in the support, an air cylinder is fixedly connected to the support, an air cylinder rod is arranged at the lower end of the air cylinder, and the air cylinder rod is slidably connected with the support. A first motor is fixedly installed at the lower end of the air cylinder rod, a grinding piece is fixedly connected to the lower end of a rotating shaft of the first motor, a protection mechanism is arranged at the upper end of the base, and two symmetrically-arranged limiting mechanisms are arranged in the base. The problems that a core rod on the device is prevented from deviating, and waste materials are possibly splashed to eyes of personnel when the device is used for grinding can be solved.
