Week 8 - Challenge 1 - Base Bracket Design
BASE BRACKET DESIGN
AIM :
T create the class B and class C surfaces fron the given class A surface, and performing the draft analysis on the given class A surface and the final componenent .
Objectives :
- Creation of class A and class B surface .
- Creation of tooling axis .
- Performing the draft analysis.
- Convert the solid model from the surfaces .
Tooling direction
tooling direction is basically that the direction that mold pulls apart from the mold . Generally the molding machine have the two portions they are core and cavity. The core is the fixed part and tye cavity is the moveable part . The moving direction of the cavity is called tolimg direction.
Procedure for creating the tooling axis
AT starting the dummy tooling direction is created on the point of hole center .
Then one datum plane is created on at the center point of the to hole .
After that the intersection is created between the datum plane and to the surface .
After that two side lines are created where the tooling will be crtical. Then creating the bisecting line between them ,the tooling axis is created .
( Here the center dotted line is our tooling direction )
Draft analysis
The draft analysis technique is used to analyse the created part model design is manufacturable based on the draft condition applied . Here the part should be easily removed from the mold . No parts can be easily ejected from the mold if it has 90 degree profile from its base surface . The small draft angle is provided on the each and every area of the component for easy removal of the component from the mold.

Draft analysis on the final component
Class B surface
( In this surface 2.5 mm takened as the thicnkess of the component)
Class C surface
Final component
conclusion
The calss B and class C surfaces were created from the given class A surface . Then the tooling direction is created and the draft analysis is performed on the both class A and final product .
