Week 8 - Challenge 5 - Core & Cavity Design

Before going to design the Core & Cavity block first we should analyze the draft angle in the part.

Draft Analysis

Parting Surface and parting Line Creation

• Create a Boundary of class a surface

• Extra plot the "Class A Surface" using created boundary.

• Trim the extrapolated Surface with the "C-surface" wall. ( which we created when c surface Creation)
• and trim that surface(Trim.8) with a B-surface.
• now we get the bottom surface of the core Block.
• Intersect "Trim.8" with "B Surface" now we get the Parting Line

• Split "Bottom Surface Of Core Block" with Parting line we get "Parting Surface"

Core Creation

• Create a Position Sketch with 'Axis System.1/XYPlane' and Point.3 (This is used for "Tooling Axis" creation)
• and draw a rectangle around the Part. and make sure Iso-Constrained.

• Extrude that sketch we get Extrude.1 and trim that extrude with "bottom Surface of core block"
• Then Fill the top surface, we get Core Block

Cavity Creation

• Trim "B-Surface" with "Extrude.1" we get "Trim.12"
• "Trim.12" upper surface of Cavity Block.
• Fill the Bottom and we get completed Cavity Block
