AI Technical Summary
Technical Problem
Existing molds for portable storage boxes cannot form hollow handles in one piece, resulting in high production costs and low efficiency. After being formed separately, they need to be assembled manually, which increases labor costs.
Method used
By using dynamic pressure blocks and shaping blocks in combination with an arc-shaped core plate and an arc-shaped groove design, the hollow handle is integrally formed and can be easily demolded through the cooperation of the arc-shaped core plate and the arc-shaped groove.
Benefits of technology
This technology enables efficient molding of hollow handles, reduces production costs, simplifies the production process, avoids manual assembly, and improves production efficiency.
