The invention discloses a double-color mold capable of preventing products from falling off. The double-color mold comprises two rear mold bodies which are the same in structure; each rear mold body comprises a lower mold plate and a lower mold core; the formed first-color products are left in the lower mold cores; two sliding blocks are arranged on each lower mold plate, and the sliding blocks are slidably connected to the tops of the lower mold plates through guide sliding straight grooves; mounting holes are formed in the groove bottoms of the guide sliding straight grooves, and the mounting holes are located in the sides, away from the lower mold cores, of the sliding blocks; vertical oil cylinders with upward output shafts are mounted in the mounting holes, and lifting blocks are connected to the output shafts of the oil cylinders; first bevel faces are arranged at the upper ends of the lifting blocks and incline in the direction of the lower mold cores from top to bottom, and thesides, away from the lower mold cores, of the sliding blocks are provided with second bevel faces corresponding to the first bevel faces; and reset springs and pressing blocks are connected to the sides, close to the lower mold cores, of the sliding blocks, the reset springs are fixed into the guide sliding straight grooves, and the pressing blocks are located above the guide sliding straight grooves. According to the double-color mold capable of preventing the products from falling off, the problem that the first-color products are prone to falling off when rotating along with the rear moldbodies is solved effectively.
