Week 8 - Challenge 1 - Base Bracket Design

Base Bracket

Aim:

To design the complete solid model of Base Bracket with the help of Class A surface(input) by creating the tooling axis and analysing the draft angle.

Draft angle:

Draft angle (the degree of taper of the side wall of the mold or the angle of clearance designed to aid removal of a part from a mold) increase causes a linear decrease of the force required to remove a molded object from a mold.

Tooling Axis:

The tooling axis is a direction along which the core and cavity tends to move. Here the tooling axis is created in z direction, which is normal to the surface of the base bracket.

Draft Analysis of Class A surface:

The minimum draft angle for the design of plastic components is 3 degree.

Draft Analysis of Final model:

Here the complete solid model is achieved the minimum draft angle of 3 degree.

Conclusion:

Thus the complete solid model of the Base Bracket is formed from the Class A surface(input) and the analysed draft angle is 2.9 degree.
