Week 9 - Attachment Feature Creation - Challenge 2

1. Below image represent proper tree structure.

2. Below are the all view of the plastic component, which is designed with the help of given Class A surface after creating the B and C class surface.

3. Draft Analysis of Class A Surface:

To make sure easy removal of the part from the die, sufficient draft should be provide on surface which is paraller to tooling axis because these surfaces are penedicular to the tolling direction.

At first feasibile tooling axis has been decided (highlighted with Blue colour in below image), keeping the parameters in mind that part should be easily removale and havig cost efective tooling. After deciding the toolindg axis draft analysis has been done which can be seen at below attaced image. As we can see all surface are green which means it has 3 degree of draft, there are two portion where its showing red colour and after carefully analysing it, i found that those surface having 1 degree of draft and as this is class A surface and we dont have rights to change is so we have to ask to increase. but in our case it is not possbile so we will proceed futher

3. Draft Analysis of Plastic Part: Draft has been done after designing the plastic part, same tooling axis used which was used for class A surface as you can see everywhere 3 degree has been maintained.

Bottom surface showing blue colour which means it has less than 0 degree draft but this surface will be clear from downward direction of lower half part of the die so if i switch the direction which is in next image, now you can seen now its green which means it is good to go further. Dog House wall is also in red colour because that wall having 1.5 degree draft for dog house draft analsys refer to dog house draft analysis.

4. Dog House Draft Analysis: All outer wall of dog house having 1.5 Degree draft which is good for releasing part from die

5. Design of Dog House: Wall thickness at the contact of part should be 40% of main part thickness here as you can see in below picture that it is maintained 1mm because main wall thickness is 2.5mm.

C Height should be in between 3-6 kindly refer to below attaced pciture for the same.
