Graphical User Interface for Cooling Line Functions and Surface Rendering

by Chen, Xiaorui

Abstract (Summary)
The cooling system is a subsystem related to die casting process technology. The location of cooling lines is a very important factor for an ideal die casting die. Cooling prevents the die from overheating, which may cause premature die failure, and helps the die to keep a uniform temperature distribution and shrinkage to obtain favorable surface finish and longer die life. However, cooling channel placement is often designed by guesswork or by past experience. It is very expensive and time consuming to modify the improperly placed cooling channels after the die has been built. The current work involves implementing a friendly Graphical User Interface to design and modify the cooling lines in CastView, a design visualization program. The system provides three methods to specify a cooling line: directly input coordinates of the cooling line nodes, orthogonal sketch and free sketch. The system also allows the user to modify an existing cooling line by changing its node coordinates, orthogonal editing, or graphical editing. It is highly desirable to design the part with a reasonably uniform wall thickness that avoids abrupt changes in wall thickness. In order to give the designers an overall view of the wall thickness throughout the part, surface rendering is applied. The skeletons achieved during thin section analysis are used. From the skeletons, the thickness values are expanded out until reaching the part surface so that the wall thickness can be displayed on the part surface.
