Week 8 - Challenge 5 - Core & Cavity Design

AIM:-

To create Core and Cavity design for Switch Bezel.

OBJECTIVES:-

• Create core and cavity block of switch bezel body.
• Create a parting line and parting surface.
• Performing draft analysis on switch bezel.

PARTING SURFACE:-

To create a parting surface we need to first create a parting line. The A-surface of the bezel is extrapolated with its outer boundary. It is then trimmed with C-surface. This trim is intersected with B-surface to form a parting line. The trimmed surface of A and C is again trimmed with a B -surface. This surface is split with parting line to form a parting surface.

CORE DESIGN:-

A point is created in the middle portion of depression. With this point as origin an axis system is formed. With the axis system, a rectangular sketch is created as shown below. It is extruded to the required limit and trimmed with parting surface. This forms the closed surface of the core. A solid object is formed with closed surface command.

CAVITY DESIGN:-

The same rectangular sketch used for the core is extruded in opposite direction. Vacant portions are filled through the fill surface command. The resultant surface is trimmed with the parting surface to form the closed surface of the cavity. The solid object is formed with close surface command.
