AI Technical Summary

⚠Technical Problem

In existing plastic chair molds, a cooling structure cannot be installed in the middle template area, resulting in low cooling efficiency and affecting the overall cooling effect of the mold.

⚗Method used

The mold employs a combination of an upper mold, a lower mold, and an inclined middle mold, with cooling components installed within each of the three mold layers. In particular, a built-in cooling component is installed within the middle mold, which, combined with an air-cooled connector, provides cooling. This, along with a moving positioning structure and an ejection mechanism, enhances the mold's cooling efficiency and demolding reliability.

🎯Benefits of technology

It achieves efficient cooling of the entire area of ​​the multi-dimensional curved plastic chair, improving cooling efficiency by more than 30%, ensuring accurate positioning and reliable demolding of the product, and avoiding product deformation or damage.
