AI Technical Summary
In the existing technology, when the radar bracket and the front grille are integrally molded, demolding is difficult, especially since the demolding directions of the radar bracket and the front grille are not consistent, and the internal pulling structure of the card hole interferes with the radar bracket, making it impossible to achieve smooth demolding.
The internal pull-in inclined ejector linkage structure is adopted, which includes an inclined ejector seat, an inclined ejector block, an internal pull-in fixing block and an inclined ejector rod. The inclined ejector rod drives the core block of the card hole to be pulled inward, so as to realize the smooth demolding of the radar bracket.
This method enables smooth demolding of the radar bracket and front grille after they are integrally formed, avoiding interference from the demolding structure and improving production efficiency and mold life.
