The uneven cooling of traditional automotive headlight frame production molds leads to deformation and internal stress concentration, resulting in long cooling times and difficult demolding, which affects product quality and production efficiency, and increases costs.
The design incorporates a cooling device and a demolding assembly. The cooling device achieves uniform cooling through a condensate pipe connecting the outer and inner layers of the mold box, while the demolding assembly uses a second cylinder to drive the mold box to slide and connect with the slide plate, ensuring stable demolding.
This achieves uniform cooling speed across all parts of the lighting frame, reducing deformation and stress, shortening cooling time, improving production efficiency, and reducing scrap rate and production costs.
