Week 8 - Challenge 1 - Base Bracket Design

Aim: Create the Base Bracket Plastic component through the given Class-A surface. To begin with, the tooling axis for the given Class-A Surface should be created meeting the requirements of the draft angle and at the end perform the Draft analysis on the model.

INPUT CLASS-A SURFACE:

Draft analysis report for both the given Class-A surface and the final plastic component:

DRAFT

Draft angle is nothing but providing some tapered portion to the part for easy removal of the component from the mold during manufacturing. This is especially done in the case of plastic component design having a complex shape. Mostly the 3-degree draft angle is provided but it can vary depending upon the component which is to be designed.

Before providing a draft angle we need to decide on the tooling axis also known as the molding axis considering the faces which can cause issues while manufacturing.

TOOLING AXIS

It is nothing but the direction in which the mold opens and closes the draft angle needed to be provided by considering this tooling axis.

We can create a tooling axis by using the bisecting method.

In this method, we select the surfaces which can create problems and take intersections in the x and y direction. By using these curves we draw two lines and then draw a bisecting line from these two lines in the x-direction and y-direction.

If it is done in x-direction then it is called a tooling axis clearing x-direction and if in y then tooling axis clearing y-direction.

After completing this we need to draw a final line bisecting this two tooling axis in X and Y direction to get our final output.

DRAFT ANALYSIS OF THE CLASS-A SURFACE:

The above image shows the draft analysis in which green color surfaces shows that they are having an angle of more than 3 degrees.These are the results of the draft analysis which are very crucial for determining the feasibility of the product.

DRAFT ANALYSIS OF THE SOLID PART:

The above image shows the draft analysis in which green color surfaces shows that they are having an angle of more than 3 degrees but the surface in red color shows it is less than 3 degree that is having an angle of 2.5 degrees. These are the results of the draft analysis which are very crucial for determining the feasibility of the product.
