Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional casting methods face inefficiencies in filling molten metal into desired cavities due to prolonged solidification times and heat transfer issues, leading to incomplete filling and difficulties in solidifying molten metal within the desired cavity.
Innovation Solution
An automatic pouring machine equipped with a unit that supplies pressurized gas and granular material to the mold, ensuring the molten metal is squeezed into the desired cavity and plugged, allowing it to solidify efficiently by transferring heat to the granular material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If pressurized gas is supplied through the sprue to fill molten metal into a desired cavity, then the molten metal can be confined and filled into the desired cavity, but the pressure needs to be maintained for a long time until solidification and the solidification time becomes long and inefficient
Solution Approach 1:
The invention extracts the harmful effect of prolonged pressurization by removing the sprue after pouring, allowing the pouring cup to be opened and molten metal to be quickly discharged. This eliminates the need to maintain pressure during the entire solidification process, resolving the contradiction between filling accuracy and solidification time.
Solution Approach 2:
The invention performs preliminary action by pre-positioning the pouring cup at the sprue opening before pouring begins. This allows immediate confinement of molten metal into the desired cavity upon pouring, ensuring filling accuracy without requiring prolonged pressurization maintenance.
2Manufacturing precision
If filling material is supplied to the cavity through the sprue before the cavity is filled with molten metal, then cavities other than the desired cavity can be filled with filling material, but heat is transferred to the filling material so that the temperature on the surface of the molten metal becomes low and the molten metal may solidify before the desired cavity is filled
Solution Approach 1:
The invention removes the sprue after pouring to eliminate the source of heat transfer to filling material. This prevents the filling material from cooling the molten metal surface, ensuring the molten metal maintains its temperature and can be quickly filled into the desired cavity without premature solidification.
Solution Approach 2:
The invention uses a pouring cup as an intermediary device that allows selective cavity filling without direct contact between filling material and molten metal. The pouring cup confines molten metal and enables precise filling into the desired cavity while preventing heat transfer to filling material in other cavities.
3Ease of manufacture
If the runner and sprue are needed only for filling molten metal into a cavity during pouring, then these parts can be separated from the product, but the time to solidify the molten metal in the desired cavity is prolonged
Solution Approach 1:
The invention extracts and removes the sprue after pouring, allowing the pouring cup to be opened and molten metal to be quickly discharged from the runner system. This eliminates the need for the runner and sprue to remain in place during solidification, reducing solidification time while still allowing easy separation of these parts from the final product.
