Description

Technical Field

[0001] The present application relates to the technical field of automobile parts design, and in particular to a method, system, equipment and medium for designing plastic parts packaging equipment. Background Art

[0002] For large-sized products such as automobile bumpers, fenders, and anti-scuff strips, when the transportation distance between suppliers and OEMs is long, how to design packaging equipment has also become a concern in the design of large products. Today, when recycling equipment is widely used in bumper products, packaging equipment has also become an important part of ensuring product quality. During the transportation of products, it is necessary to enhance the surface stability of plastic parts through the structural design of tooling and equipment. Especially for large painted parts such as bumpers, it is necessary to prevent product deformation during transportation and avoid scratches on the paint surface. Therefore, the design of packaging equipment has also become a concern for OEMs.

[0003] Plastic parts tooling also affects the structural design of the product. As lightweighting is being promoted today, the role of tooling is becoming increasingly apparent, becoming an important part of the product series process. In the product development stage, product data, simulation, and packaging tooling are developed synchronously and in coordination. Through a series of simulations on the product side, the feasibility of tooling is confirmed, thereby locking in the product structural data and the basic structure of the tooling. This can not only ensure the surface stability of the product during transportation, but also improve the installation effect of the entire vehicle. However, at present, there is still a lack of a reasonable design method for plastic parts packaging tools. Summary of the invention
