Week 10 - Challenge 3 - Door Trim Lower with Engineering Features

Aim:--

Create the door trim lower 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.

Create the heat stakes and the locators considering the design rules mentioned in the video for the door applique.

to be able to create solid from the given class-a surface, by considering tooling axis and draft analysis.

Class-A surface: -it is an aesthetic surface and which is visible to the customers i.e., top surface,

The wall is extracted and a point was created at the centre of the base wall, using that axis system is inserted,

Tooling axis: --

~ the tooling axis is the tool movement axis (core/cavity).

~ this axis will decide the draft direction.

Class B surface

The surface which is thicken and applying the engineering features in it that surface is called as class b surface, now offset the class a surface for 2.5mm in the inward direction.

There will be gaps in the fillet areas and use multiple extract command and select the surface and extrapolate it and trim and use edge fillet similarly extrapolate the remaining surfaces which have gaps and follow the same steps

Class C surface: -

The surface which joins the class a and b together that surface is called as class c surface.

By using the multiple extract command create a boundary and use smooth curve option to smooth the curve and use sweep command to create a surface along "with reference surface".

And the angle of draft given in sweep is 87 degrees.

Join surface a with surface c: -

Performing draft analysis for the whole block: -

performed the draft analysis it had cleared the draft analysis for 3 degrees.

Create the heat stakes and the locators considering the design rules mentioned in the video for the door applique.

Door trim with locators and heat stakes:

Design of 4-way locators:

I took a geometrical set and i had drawn a sketch with reference of plane and projection point, after i given pad for the sketch with in the dimension limits as, with neutral fibre.

Thickness = 1.3

I had given a draft = 0.5, and given a fillet on the locator’s side,

Design of heat stakes with ribs:

I took a geometrical set and i had drawn a sketch with reference of plane and projection point, after i given pad for the sketch with in the dimension limits as, with neutral fibre.

I had given a draft = 0.5, and given a fillet on the locator’s side,

Draft analysis of the locators and heat stakes: -

The draft angle for heat stakes and locators is 0.5deg.

Final component: -
