The invention discloses a cutting device for automobile interior foam. The cutting device comprises a base. A sliding groove is formed in the base. A sliding plate matched with a sliding groove box is arranged on the sliding groove. The sliding plate is provided with a carrying table. A rotating shaft is arranged on the base. A first belt and a gear are sequentially arranged on the rotating shaft from top to bottom. The gear is connected with one end of the sliding plate in an engaged manner. The first belt is rotationally connected with an output shaft of a first motor arranged on the base. Bolt rods are fixed to the two sides of the base correspondingly. By means of the cutting device for the automobile interior foam, rollers, rotating cylinders and the bolt rods are arranged so that a heating wire can conduct the vertical movement in the vertical direction, and universality of the cutting device is improved; and the heating wire is adjusted so that the heating wire can be used for cutting the foam to be in different shapes, the cutting frequency for meeting the requirements is reduced, and the working efficiency of people is improved.
