AI Technical Summary
The existing mold structure for truck ventilation masks is not adaptable enough, resulting in uneven rounded corners and dimensional deviations in the ribs after molding. Furthermore, manual prying is required when removing the parts, which reduces production efficiency.
The design employs an upper and lower die arc insert, which are respectively embedded in the corresponding die base. Combined with independent upper and lower die rib inserts, a rib forming cavity is formed. It is equipped with matrix-distributed elastic ejector components to ensure a stable connection between the inserts and the die base, preventing displacement. The inserts are automatically ejected after the material plate is formed, reducing manual intervention.
It improves the smoothness and consistency of product edges, reduces dimensional deviations, increases production efficiency, and reduces the labor intensity of workers and the risk of product damage.
