AI Technical Summary

Technical Problem

Existing extrusion dies are easily damaged under the pressure and flow rate of molten fluid, and lack effective protective designs.

Method used

The design employs a combination of fixed components, pressure-reducing components, and barrier components, including mounting base, connecting plate, fixing frame, pressure-reducing pipe, buffer spherical shell, connecting pipe, first stop and second stop, etc., which are fixed by bolts and welding to reduce the pressure and flow rate of the molten fluid, and a reinforcement structure is set on the outside of the mold to protect the mold from collision.

Benefits of technology

It effectively reduces the pressure and flow rate of the molten fluid on the mold, prevents mold damage, protects the mold from collisions with other components, and extends the mold's service life.
