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

Report

Draft Analysis is very usefull tool to analysis the draft value of plastic components as well as sheet metal components. In molding process, no part can ejected from the tool if it is having a straight 90 degree profile from its base surface.so, we provide small angle to each and every area of the component to get an easy removal of the component from the tool. Draft analysis technique is used to analyze whether our part model created in cad is manufacturable based on the draft condition applied.

In this Door Trim components we check the draft analysis of given class-A part. for analysis draft firstly check the which plane is suitable for molding then after we draw tooling axis.

Process to draw Tooling Axis:-

• Extract the base surface of Door Trim.
• Untrim the extract surface.
• Pick the point on the surface with zero co-ordinate.
• Draw the line in this point in Y direction that are our tooling axis

Class A Draft Analysis

After creating tooling axis, we perform draft analysis.Draft analysis workbench available in part design, Generative shape design, wireframe and surface for building and free style shaper workbench. Draft Analysis workbench available in Insert>Analysis>Draft Analysis. Firstly change the view mode to customize view parameter and select material option from the mesh and select material. After That Drag the axis simble and fited in the tooling axis. Two sub window pop up one is for draft deviation colour bar and second is menu bar. Green colour part represent ok for manufacturing but second side show blue that mean need to thick the part so we we create B surface and C surface then we make solid using close surface operation after that we check draft analysis one more time like class A.

Heat Stake

Heat Stake is used to joing the dissimilar material. its also called plastic welding in other term.Creat Heat Stake on given Point.

Locator

Locator are used to arrest the moment of the part with respect to direction. in this chgallenge we draw four way locator
