MATERIAL FEEDING APPARATUS FOR DIE CASTING AND MATERIAL FEEDING METHOD USING THE SAME

摘要

The present invention relates to a method and an apparatus for supplying raw materials for vacuum or inert atmosphere die casting in order to improve productivity by smoothly supplying raw materials to a crucible and to prevent damage to the crucible by minimizing a collision between the raw materials and crucible when the raw materials are put into the crucible in the inert atmosphere or vacuum die casting. The present invention comprises a raw material supply pipe, first and second valves, a raw material holding unit, a vacuum discharge unit, a raw material transfer pipe, and a driving unit for transferring the raw materials. The raw material supply pipe supplies the raw materials through the falling of the raw materials. The first and second valves are installed in the raw material supply pipe to be vertically separated from each other and open and close the raw material supply pipe. The raw material holding unit is installed between the first and second valves inside the raw material supply pipe and either receives the falling raw materials or allows the raw materials to fall down. The vacuum discharge unit supplies vacuum to a space between the first and second valves from the inside of the raw material supply pipe. The raw material transfer pipe provides a path for supplying the raw materials falling from the raw material supply pipe to the crucible installed in a vacuum chamber. The driving unit for the raw materials supplies the raw materials falling from the raw material supply pipe to the inside of the raw material transfer pipe to the crucible along the raw material transfer pipe.
