Problems solved by technology
[0002] At present, in order to achieve high performance and high cost performance for automotive interior parts, there are currently three methods for this process: After monochrome injection molding, the simulation car stitches are insufficient: monochrome has poor limitations, complicated operation, poor appearance, single tone, and not vivid
Disadvantages: The mold requires multiple sets of processes (injection molding, lamination, etc.), the cost increases, the operation of the assembly process is complicated, the cost of labor and equipment input is increased, and the defect rate is high
[0004] Insufficient for two sets of molds to rotate and switch injection molding (double barrel injection molding): the cost of the mold increases, and 2 sets of molds are required; the production cycle time is long

The invention discloses an automobile door trim fluorescent seam injection mold and a molding method thereof. A dual-color electric high-pressure injection molding machine serves adopted equipment. The automobile door trim fluorescent seam injection mold is characterized in that the mold comprises a male mold bottom plate, a female mold bottom plate, a male mold body, a female mold body, mold feet, a push plate, an inlaid sliding block and a dual-color hot runner; the male mold body is mounted on the mold feet and the male mold bottom plate; a female mold is mounted on the female mold bottom plate; the push plate is arranged between the male mold bottom plate and the male mold body; and the dual-color hot runner is arranged between the female mold and the female mold bottom plate. In addition, the invention discloses a composite injection molding method. Two injection molding barrels are used for achieving injection at the same time in an L shape, a door trim shows different portions,different materials, different hardness degrees and chemical foaming and has fluorescent light of different colors, and the product type is more diversified.
Description
technical field [0001] The invention belongs to the technical field of injection moulds, and in particular relates to an injection mold for fluorescent sewing thread of automobile door trims and a molding method thereof. Background technique [0002] At present, in order to achieve high performance and high cost performance for automotive interior parts, there are currently three methods for this process: After monochrome injection molding, the simulation car stitches are insufficient: monochrome has poor limitations, complicated operation, poor appearance, single tone, and not vivid . [0003] Disassemble the door panel structure and use the assembly form (different parts are injected with different colors and physical materials). Disadvantages: The mold requires multiple sets of processes (injection molding, lamination, etc.), the cost increases, the assembly process is complicated, the cost of labor and equipment input is increased, and the defective rate is high.
