AI Technical Summary
In the existing technology, when forming large-curvature T-shaped ribs, the R-zone forming does not meet the requirements, resulting in problems such as excessive resin, wrinkles, and abnormal mold adhesion, leading to the scrapping of parts.
The system employs a combination of a first L-mold, a second L-mold, and a bottom mold. The large curvature section of the first L-mold is filled with a conformal soft mold. Combined with the design of a chute and a slide rail, the deformation of the bottom mold is controlled during the curing process, avoiding uneven pressure on the R-zone. The system is assembled using a non-porous isolation membrane and a breathable felt to ensure uniform compaction.
It effectively solved the problems of resin overload, wrinkles, and abnormal mold adhesion in the R zone after molding, thus improving the product qualification rate.
