Project 2

Hi,

Here I'm submitting the final project of mine on CPU FAN BEZEL model.

Procedure followed for core & cavity surface creation of CPU FAN BEZEL model :

First, I made the Draft analysis for the given component & verified the positive & negative drafts on the yellow region.
Then, I scaled the component to 1.006(0.6%) as assumed the product as ABS.
Then I created parting lines using 'parting lines' tool.
And I created the shut-off surface, for the open cut-outs present in the product.
And I created lofted surface, for the open cut-outs present in the product.
Then, by using 'ruled surface' swept all surfaces along the path of the line drawn.
And I copied the surfaces using 'move/copy bodies' tool.

And I did 'knit surface' with one of the parting surface and cavity surface & another parting surface and core surface respectively.

Procedure followed for core & cavity block creation of CPU FAN BEZEL model :

For the mold block creation, I inserted the surface model into a new assembly.
Then I have aligned the sprue location to the assembly origin & fixed it.
Then I have created a sketch of a square in a new part as core steel for creating the 2d profile & 3d profile as well.
Then I created a copy of the parting surface using 'offset surface' tool.
And I extruded the sketch of the core steel part upto 200mm on both sides.
Using 'move face' tool, have aligned the height of the core steel part.
Then I have used 'cut with surface' tool to create 3d profile on the core block.
Using 'combine' tool, I have combined both 2d & 3d blocks.
For the cavity steel part, I used 'convert entities' as the same sketch created in core steel part.
Then I created a copy of the parting surface using 'offset surface' tool.
And I extruded the sketch of the core steel part upto 200mm on both sides.
And using split tool, I have splitted the 2d & 3d blocks.
Using 'move face' tool, have aligned the height of the cavity steel part.
Then I have used 'cut with surface' tool to create 3d profile on the cavity block.
Using 'combine' tool, I have combined both 2d & 3d blocks.
Then, for avoiding rubbing between core & cavity blocks, moved 2mm where rubbing.
Finally, I have assigned the respective colours to the core & cavity blocks individually.

Procedure followed for insert 1 creation of CPU FAN BEZEL model:

First, I have drawn the 126.5 diameter on the top plane of the core steel part & splitted it using 60mm offsetted plane from the bottom face.
For mounting the inserts, I use M6 C/B from bottom on each insert using ‘hole wizard’ tool.
And for the same pitch I have put tap holes on the each insert as well.
Then I have assigned yellow colour to the insert.

Procedure followed for insert 2 creation of CPU FAN BEZEL model:

First, I have drawn the 146 diameters on the top plane of the core steel part & splitted it using 60mm offsetted plane from the bottom face.
Then, I have grouped the inserts using combine tool.
For mounting the inserts, I use M4 C/B from bottom on each insert using ‘hole wizard’ tool.
And for the same pitch I have put tap holes on the each insert as well.
Then I have assigned sky-blue colour to the insert.

Procedure followed for slider creation of CPU FAN BEZEL model:

After creating inserts, I have planned to create sliders for side undercuts.
Initially, I have created a mid-plane to the part.
Then created a sketch for slider & splitted it using ‘split’ tool from the top.
Then created a extension wall for the slider travel.
And created wedges, fillets to the sliders.
Then saved the sliders into a new Parasolid file & insert it into the assembly as slider 01.
And accordingly inserted the slider block into core & cavity blocks, using ‘combine’ tool subtracted the projections.
Then using ‘move face’ have arrested the openings on the core block.
Then created the locking mechanism, bolts & screws to the sliders.
After creating a slider I have patterned for further 3 sliders & doing the same operations as well.
Finally assigned yellow colours to the slider blocks.

Procedure followed for ejector pins, plates creation of CPU FAN BEZEL model :

First, I have started with ejector pin sketch of diameter 6 on the top face of the core steel.
And extruded it upto the part surface & 250 offset from the same surface.
Then created ejector pin reliefs on the core block of 6.95 diameter for all the holes & extruded cut it to 84mm.
Then I created ejector plate on the top of the ejector pin of 10mm thickness & offsetted 45 each side on the core block.
Then created ejector end plate on the top face of the ejector plate of 15mm thickness and of the same dimension.
And I created an ejector pin lock of 10 diameter and a flat face for orientation on all the pins.
And the same sketch offsetted on the ejector plate of 12mm and the same flat face sketch & used ‘extruded cut’ on it.
Finally, I have given respective colours to the ejector pins, plates.

Procedure followed for runner & gate system creation of CPU FAN BEZEL model :

First, I have created the runner path on the cavity block of 120 diameter on the origin of the block & used ‘extruded cut’ of 12mm.
Then for the runner path, I have created diameter 5.8 on the cutted surface and the draft angle of 3.5 degrees outwards through all.
And converted the drafted end diameter to the top face of the core block & used ‘extruded cut’ of 5mm on it.
Then for the gate location, I have created a line on the core block nearby the previous cut & extruded it to 4mm x 4.5mm till the opening of the part creation.
And I have drafted the side faces of the block to 10 degrees inwards.
Then I have filletted the bottom edges of the block.
Then I have created another triangular sketch to the front of the block & extruded it to 0.5mm.
Then filletted its front edges & combined both the blocks using ‘combine’ tool.
Finally, subtracted the block with the core block using ‘combine’ tool.

Procedure followed for air vents creation of CPU FAN BEZEL model :

First, I have offsetted the outer circular edge of the model on the core block.
Then extruded it 1mm to some extend on both sides.
And splitted it using ‘split’ tool & consumed the cut body.
Then moved the bottom face of it to 1mm using ‘move face’ tool.
And filletted the bottom edges.
Then created an inner block to it of a diagonal shape upto its same surface.
And moved its face to 0.02mm on the bottom using ‘move face’ tool.
And combined both the blocks using ‘combine’ tool.
Then created a path for the air vent as a sketch on the perpendicular side of the above features, and extruded it upto the same surface.
And filletted its bottom edges.
Then combined these two blocks using ‘combine’ tool.
Then I have mirrored the all the block on the opposite side.
Then, finally combined both the blocks with the core block using the same ‘combine’ tool.
Finally given respective colours to the air vent paths.

Procedure followed for cooling channels creation of CPU FAN BEZEL model :

I have created the cooling channels on the core block.
I have used hole wizard to create the path for the cooling channels.
I have used M10 Socket Head Cap Screw for the channel paths.
I have created the holes on all the faces by merging the holes for the paths.
I have assigned the paths little away from the part section, to avoid intersections.
Finally, given different colours to the paths.

And, here I have submitted my final project.
