Week 8 - Challenge 1 - Base Bracket Design
Given class A surface is analysed based upon the parameters of injection moulding standards, component is studied visually in X, Y & Z directions to conclude the best suitable direction for creating tooling axis.
In the below model Z direction is selected for creation of tooling axis for the reason it covers all the major surfaces of the components, use of side core and other complex plastic injection moulding features are avoided. With the help of this manufacturing cost and complex operations are reduced, which directly helps to reduce the cost of component.
To created a tooling axis, on the class A surface, point is created on mid region. with the help of the point dummy tooling axis is created for our reference. A parallel plane is created with reference to the point, on the created plane using intersect command, intersecting sketch of the class A surface is created. The major draft faces are selected and with using that face as a reference tooling axis is created with the help of line command.
Draft analysis report for the given Class-A surface and the final plastic component
Draft analysis feature helps to check the class A surface, whether it is created as per the moulding standards. An important factor that has to be considered during moulding design is no faces of the component should be in a perpendicular to the base plane. All the faces should be at specific angle as per requirement (say 3 degrees). Using draft analysis feature the surface feasibility can be studied, initially the cordinate system should be placed on the tooling axis, base upon the cordinate system, angular value of the face is viewed with the help of colour distribution. The required max and min angle value should be feeded in the scale region. Based upon the preset angle value the colour of the component varies. Using the colour which is displayed on the component is concluded with whether the design standards is followed are not.
