Week 9 - Project 1 - Door Trim Lower with Engineering Features

Tooling Axis creation:

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.One more sketch is created on the ZX plane of Axis System for considering the lone side face for tooling direction. In the sketch, a line is drawn with a suitable angle to the loneside face so that with the resultant tooling axis the side face is cleared. Then resultant tooling axis is created using the bisecting method.

Draft Analysis of Solid Model

Same steps are followed to get the draft analysis of the solid part as in Class A Surfaces 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.
