AI Technical Summary

Technical Problem

Traditional casting equipment is prone to turbulence and bubbles during the flow of molten metal, which can lead to defects such as porosity and looseness inside the casting, affecting the quality and mechanical properties of the casting.

Method used

The metal casting device with a spiral flow guiding structure uses a rotating rod and spiral blades in the spiral section. The rotating rod is driven by a drive motor to rotate, so that the molten metal can be spirally guided. The flow rate and velocity are controlled by the up and down sliding of the piston. It is also equipped with an internal cavity of the piston, a vent hole and an exhaust module to discharge the gas in the mold cavity.

Benefits of technology

It achieves uniform and stable inflow of molten metal, reduces porosity and looseness defects, improves the quality and density of castings, and enhances the mechanical properties of castings.
