Week 8 - Challenge 2 - Base Bracket Design

PLASTIC BRACKET DESIGN USING CLASS A SURFACE:

DRAFT ANALYSIS:

Draft Analysis is a process to check the eligibility of the designed product to be manufactured without getting damaged. To get successful in draft analysis, the part should have a draft of minimum 0.5 to 3 Degree. This draft should be in reference with the tooling direction of the core and cavity during molding process.

TOOLING AXIS:

Tooling Axis is the tool travel direction. here the core gets along the axis of the tool travel. Hence creating a tool axis is most important and firsrt process for maing ay plastic part.

To Create a Tooling Axis, We have to first verify which direction is best suitable for the tool to produce the part in an efficient way. This can be usually done by just assuming the direction by examining the given surface.

Now, the Tooling axis is created by bisecting the lines which are hardly parallel to the Dummy Tooling Direction.

PROCEDURE FOR BISECTING THE LINES:

This image shows the intersection lines of the surface. Now the lines which seems almost vertical will be used for bisecting.

The lines which are almost vertical are taken for creating bisecting lines. Thus the lines created above will be used for bisecting and getting the Required Tooling Axis.

Hence by bisecting the two lines, we sucessfully created the tooling Axis (Black Dotted Line).

Now, We are ready to design the plastic part using tooling axis as the reference.
