The utility model relates to the technical field of automobile part manufacturing molds, and discloses an automobile
back door double-color
mask mold which comprises a fixed mold and a movable mold, a forming cavity is formed in the left side of the inner wall of the fixed mold, a plurality of injection molding pipes are communicated with the right side of the inner wall of the forming cavity, and flow sensors are communicated with the right sides of the outer walls of the injection molding pipes on the upper side. The right sides of the
multiple injection molding pipes communicate with external connecting pipes, a cooling pipeline is fixedly connected to the inner wall of the fixed mold, a sliding groove is formed in the right side of the outer wall of the movable mold, a sliding block is slidably connected to the inner wall of the sliding groove, and a plurality of inserting rods are slidably connected to the left side of the outer wall of the sliding block. According to the utility model, through the structural matching of the sliding block, the spring and the
electromagnet, the accurate switching of injection molding areas is realized, the problem of inaccurate movement and positioning of the sliding block is solved, the problems of product deformation and infirm combination in the prior art are effectively improved, and the product quality is improved.
