AI Technical Summary
In existing technologies, when using a lost foam casting oscillating frame, the material flow is uneven, resulting in numerous air bubbles and affecting the yield.
The system employs a multi-sprue design, including a main sprue, left and right connecting sprues, and connecting runners. Combined with internal supports, side supports, and reinforcing frames, it features a main vent, side vent, and apex vent to ensure uniform flow of molten metal and gas discharge.
It achieves uniform casting of molten metal, reduces porosity, increases yield, and ensures product support and molding effect.
