Part selection
A moldable part has to be selected from online library (Grab-CAD) and modified according to criteria given by the instructor.
Surfacing
The selected part has to be converted to a wire frame and using different surface feature commands all the surfaces has to be recreated and sew together.
Mold design
The surfaced part has to be thickened and then using the same part a fully functional mold has to be created. A core and a cavity have to be created with full ejection system, ejector pins and water lines for mold cooling.
CAM Programming
After the mold has been created the main component core and cavity have to be imported into Power-mill and a full CAM programming has to be done which then can be machined in real life.
DESIGN DESCRIPTION
The selection of design was based on parts that can be injection molded in real life. From online source grab cad the few part were chosen and sent to our instructor Mr. Andrew K. The part then modified according to specifications and then the surfacing was done by extracting wire frame from the same body. In the design part initially I has issues with the part ribs, they were difficult to surface from wireframe. So, I removed the ribs from the original part and keep the part as a single surface. Once it was surfaced I thicken it and the scale the part by 10% as a part shrinkage allowance. In the NX, the mold was created from the part using top down assembly format. All the component were modeled using linker geometry. The whole mold assembly was made according to criteria given. In design part I have not faced any issues and everything in design part was completed as expected.
