Challenge

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

AIM -Create the Door Trim Plastic component through the given Class-A surface.

CLASS A SURFACE

STEP 1 - Check the connectivity/continuity of the surface using the boundary tool or the close surface tool.

Step 2 - Creating TOOLING AXIS

Check the best tooling direction by visualy considering the cost factor in mind. Here the best tooling direction is Y direction because other two direction are problem making complex.
Etract the base and a point was created at the center of the extract.
Using the axis system and point we create a line in y direction. And that is our tooling axis.

[ TOOLING AXIS - The direction in which mold open and close or simply say that tool movement axis.It decide the draft direction]

STEP 3 - DRAFT ANALYSIS for CLASS A

Here the given class A surface is subjected to the daft analysis with draft angle 3 degree.
From insert the draft analysis tool is taken, here we placing the compass to the tooling axis.
Click on the class A, then we get a green colour on top and blue in the bottom. It means that draft angle decreasing from 3 degree to 0 degree.

Step 4 - Creating the CLASS B surface.

Extracting the surfaces from class A.
Using the trim,multiple extraction,extrapolate and joining commands ,then we got a Class B surface that is 2.5mm below the CLASS A

Step 5 - Creating the CLASS C surface.

STEP 6 -

STEP 7 - CLOSED SURFACE

STEP 8 - Creating solid from closed surface

STEP 9 - Draft Analysis for Part

Here the part subjected to the daft analysis with draft angle 3 degree.
From insert the draft analysis tool is taken, here we placing the compass to the tooling axis.
Click on the part, then we get a green colour on top and blue in the bottom. It means that draft angle decreasing from 3 degree to 0 degree.

B SIDE FEATURE CREATION

1) HEAT STAKES

The heat stakes are placed in the b side side of the part and here we place 16 heat stakes in the different positions on the B side.
The heat stakes has a inner diameter of 5mm and the outer diameter of 7 mm is created by using sketch and pad option. It is pad to 20mm above and 6 mm beow.
After the pad we use union trim to attach the heat stakes to the door trim part and after we filleted and drafted.
The sketch of the heat stake is given below.

LOCATORS

The Locators are placed in the B side side of the part and here we place two 4 way Locators in the different positions on the B side.
Using the sketch and pad pad option we create the locators in the different position of the b side and also provided the minimum draft and the fillets.
After we added the locators to the main door trim part.
The sketch is shown in below ,

DRAFT ANALYSIS OF THE DOOR TRIM WITH HEAT STAKES AND LOCATORS

Here the final part eith the heat stakes and locator is subjected to the daft analysis with draft angle 0.5 degree.
From insert the draft analysis tool is taken, here we placing the compass to the tooling axis.
Click on the part, then we get a green colour on top and blue in the bottom except the heat stakes area.
It means the heat stakes are not cleared using the 0.5 degree draf angle.
