Week 11 - Final project

Aim : To Create a door inner panel with reference to given Class-A surface and Create Attachment Features using Master sections Provided

Introduction: Inner panel of a car is an aesthetic & functional Component in car, It is the interface B/W the car interior & the inner working of door. It consist of Armrest, Map pocket, Bottle Holder, Lower Substrate And etc. All the inner panels are manufactured by injection moulding Process.

• Given A surface & Master section :

1) ARM REST

• Creation of Arm Rest : Arm rest A surface is Checked and improved from the Irregularities. Tooling Axis for the Arm rest is selected As the Z- direction.

• Creation Of B surface : B surface is the bottom surface on which the attachment features are produced. and B surface wont be visible to the Human Eye. As given in the master section A surface is Offseted twice once 2mm and Again for 2.5mm.

• Creation of C surface : C surface is a closure body of both the A & B surface.

• Solid Body of Arm rest :

• Arm Rest With Attachment Features

2) BOTTEL HOLDER

• Given A surface and Created Tooling Axis

• Creation of B surface for Bottel Holder

• Creating C surface

• Solid Part Bottel holder

• Solid Part with Attachment features for Bottel holder

3) MAP POCKET

• Given A surface & Created Tooling Axis

• Creation of B surface

• C surface

• Solid part

• Solid Part With Attachment Features

4) Lower Substrate

• A surface and Tooling Direction

• Creating B surface

• Creating C surface

• Solid Surface

• Solid Part With Attachment Features

5) Draft Analysis : Draft is the amount of taper for moulded or cast parts perpendicular to parting line. Draft angles are a design consideration that makes it much easier for a part to release cleanly from a mould.

• Draft report of Lower Substrate : Our Given A surface is clearing the Draft of 3 deg correspondance to the given tooling axis.

• Darft Analysis for Solid Part With Attachment Features : Solid Part is clearing the draft of 3 degrees, features as dog house is also clearing the similar darft over the main axis.

• Dog house Draft Report : Dog house is clearing draft of 0.5 degree correspondance to lifter axis.

• Draft report of attachment features : All the features are clearing the draft of 0.5 degrees.

• Draft report of Map Pocket : Part is clear 3 deg draft. some sections are not clearing draft.

• Draft analysis for Bottle holder : Some section in Holder are not clearing the draft as the A surface has defects in itself. other than that most of the parts are clearing 3 degree draft

• Draft analysis report for arm rest : Arm rest A surface itself has lot of Negetive Drafts Present in it they are reflecting in the Solid part as well.

• Final Assembled Part
