Description

Technical Field

[0001] The utility model belongs to the field of injection molding, and in particular relates to an injection molding mold for a vehicle guide plate. Background Art

[0002] Automotive spoilers usually have complex three-dimensional shapes to meet aerodynamic requirements, and in order to achieve large-scale automated production, injection molding is usually used. Compared with traditional hand-made or metal stamping, injection molding can significantly reduce unit production costs. At the same time, injection molding, using various engineering plastics, can easily produce complex shapes and reduce product weight to meet lightweight requirements.

[0003] The size of the fixed plate of the dynamic mold of the injection molding machine is usually square or rectangular, and the length and width of the rectangle are similar. In order to improve the efficiency of equipment use, the mold is usually designed to be a square or rectangle with a size similar to that of the dynamic mold. When producing long strips of automotive deflectors, the traditional solution will result in a lot of unused space inside the mold, affecting equipment utilization and production efficiency. In addition, the automotive deflector has a complex structure and is thin, which is prone to product deformation during the demolding process, resulting in quality problems.

[0004] Therefore, the above problems need to be solved urgently. Utility Model Content
