The invention discloses a mold injection molding device special for new energy automobile interiors, and relates to the technical field of mold injection molding. The mold injection molding device comprises a base, a mold combining structure and a feeding structure are arranged on the left side and the right side of the upper end of the base correspondingly, a heating structure is arranged betweenthe mold combining structure and the feeding structure, a hopper is arranged on the side, close to the heating structure, of the upper end of the feeding structure, and a material bin is arranged inthe hopper. Through the design of inner vibration grooves and guide blocks, when a windmill wheel rotates, vibration balls can move in the inner vibration grooves, and when the vibration balls move tothe surfaces of the guide blocks, the vibration balls move in the inclined direction, so that the vibration balls impact the side wall of the windmill wheel so as to generate vibration; and through the different rotating positions of the inner vibration grooves, the moving speeds of the vibration balls are different, the vibration balls impact the windmill wheel after moving so as to generate vibration, injection molding raw materials adhering to the windmill wheel are separated from the surface of the windmill wheel, blockage is avoided, and the injection molding raw materials circulate smoothly.
