Week 8 - Challenge 1 - Base Bracket Design

1. Images for varify proper geometrical set tree

Class A Surface Draft Analysis: To make sure easy removal of the part from the die, aducate 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, 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, that mean this Class A surface is good to deasign.

Different View of part:

Draft Analysis Of Part:

As per given Class A surface, class b and class c surface has been developed. With the help of Class A, B and C surface part has been design by using close body commad.

1. To insure the easy removal of the part draft analysis for the part has been carried out. As given in below image all surface on class A side and Class c side are green which mean its ok for plastic injection die moulding and enough draft is there for easy removal. Same tooling axis has been used which was used earlier for class A surface.

2. I have increased the draft anngle from 2.5 to 3 degree and as we can see top surface is green and which is having more than 3 degree draft, that mean there is no problem with this surface. There is red colour on side wall which was created by "C Surface", that mean it having less than 3 degree draft but having more than 2.5 degree draft if we look at previous draft analysis. Usually 3 degree draft is ideal , but this wall having only 2.5 mm thickness so it will not have any issue or we can also change the C class surface to insure proper release.

3. 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.
