Week 9 - Project_1 - Door Trim Lower with Engineering Features

We have to create the heat stakes and locators for the given part.

Creation of Tooling axis with appropriate draft angle.

Creation of other surfaces (eg, B and C surfaces) for creating a solid component.

Draft Analysis :

It is defined as the direction in which the mould/core and cavity open. Selection of the direction of the tooling axis depends on the ease at which components can be easily ejected.

By analysing the component the most easily ejectable direction is somewhere close to the Z direction,(might be inclined to it) so we have made a sketch on the YZ plane of Axis System) to create a bisecting line considering the 2 faces which might be difficult to be tooled.

As we know minimum draft angle for the faces of the plastic component should be 3 degrees. So the value of 2.9 degrees (considering tolerance) is provided in the Draft analysis colour mode window Inside the colour scale, the GREEN bar shows the draft angle of 2.9 or above 2.9 degrees. The blue bar shows below 2.9 degrees draft angle the other limit being and the RED bar shows the negative draft angle. As shown in the image below all the top faces and side faces of the component are green, while the bottom faces are red. The line of demarcation between the green and red faces is the parting line which divides the core and cavity halves. The solid model has cleared the draft analysis successfully as shown in the image below.

Locators :

By using the position sketch I created 2 4 way locator and 1 way 2 way locator.

2 way locator :

4 way locator :

Heat Stakes :

To crate heat stakes I extracted the outside boundary and crated the boundary by using the parallel curve I taken certain distance from it.

By using the points repetition command I created 7 points on the top.

Same as to done at the bottom side of the part.

At bottom I created 9 points.

At last there are 16 heat stakes, and 2 4 way locator and 1 2 way locator.

The final product has shown in below fig.
