Project 2

Procedure followed to create the CPU Fan Bezel mold blocks:

• Decide tooling direction and check for draft analysis
• Scale the model considering 0.6% shrinkage i.e. 1.006
• Make the parting lines using parting line command
• 
• Close the open surfaces using shut off surfaces and knit them
• Create the parting surfaces for core and cavity mold using parting surface command and knit them together
• Knit the parting surfaces with core & cavity surfaces
• 
• Create the inner/outer core blocks using boss extrude. Then use split command to seperate inner/outer block
• Offset the core/cavity surfaces and use cut with surface to form the respective blocks
• 
• To form the sliders sketch the profile such that the undercuts get covered and then use split command to seperate slider profile from cavity block
• Use boss extrude to add material and provide draft for slider. Insert into new part
• 
• Use combine(subtract body) command to form the slider profile in blocks
• Make necessary edits in the core & cavity blocks to ensure proper fit and easy movement of slider
• Provide relif between core/cavity block faces which are in direct contact
• We will have to create inserts for the inner features since the thickness is very less i.e. 1mm and the cutting tool for this thickness is not available
• Select the top plane and click on the insert's profile than use convert entities to form the sketch. Then use split command to form inserts
• 
• Use hole wizard command to form holes for bolts for fixing inserts also create holes in inserts using extrude cut
• To create the ejector pins sketch 6mm circles and extrude them.Provide proper relif and holes in core block also create pin head
• 
• Select pin head surface and sketch rectangles to form ejector plates. Also, provide pin head relif on plates
• 
• Now in cavity block sketch circle and extrude cut to form sprue.
• 
• Create air vents in the core block for air in block to escape use extrude,fillet,mirror & combine commands
• 
• Now to make the cooling channel across the core & cavity block use hole wizard command and specify M10 socket head cap screw type and create multiple cooling channels.Maintain series flow
•
