Week 8 - Challenge 4 - Coin Holder Design

Aim: To create the Coin Holder Plastic component through the given Class-A surface.

Consideration:

Wall thickness 2.5mm

Draft Angle: 3mm

Steps:

*Checking Class A Surface for surface interigity.

Close profile infer that A surface has no patched surface.

* Creating Tooling Axis

As the vertical wall are straight with no draft angle, thus tooling direction along X and Y create stright axis along Y axis.

* Creating B surface

Base Surface.

* Traiangular emboss

*Triming 

*Vertical walls

* Triming Surface

*Taper top wall

*Triming surfaces

*Outer Flange

*Triming surface

*extrploating top parting surface

Triming surface 

*defining appropriate fillets

Creating C surface

Triming A,B and C surface

Triming pocket between the vertical walls

*Coverting Closed surface to solid body

Draft Analysis

Green surface infers acheiving 3 Degree draft angle

Red Surface infers the draft angle is below 0 degree, thus need to acheiveusing special technique in injection moulding

Feature tree

Conclusion: Thus Platic Coin Holder Design is completed using Surface workbench.
