Project 1

TABLE FAN BASE

Component:

Checking Draft Analysis:

Draft analysis Examines the faces of the model for sufficient draft, to ensure that the part ejects properly from the tooling. By using draft analysis we check if there are any missing drafts in the model and do the necessary changes.
Minimum Draft angle is 0.5 degrees.

This part requires draft at the yellow area.

Scaling:

Depending on the material, the part will shrink when cooled after molding. Therefore our mold needs to be a little larger than the original so we will scale up our part.
Assuming the material for the model as ABS (shrinkage - 0.6%), the scale value is determined as (0.6/100)+1=1.006 for the model.

Parting Line:

Now we need to separate the model into core and cavity. for this, we use the parting line command.Parting lines are made to separate into core and cavity.

Shut off Surface:

We can observe that there are few openings in the part. we have to cover these parts before creating the mold. For this, we use the shut-off surface command. All the opening holes are covered using a shut-off surface.
Shut-off surface Creates surface patches to close up through holes in the molded part.

Parting Surface:

The parting surface is made along the parting line to separate the core and cavity blocks.

Cavity Surface:

Core Surface:

Cavity Block:

By using Cavity surface cavity block is created

Core Block:

By using core surface core block is created

Sliders:

There are some holes provided in the components those holes will not satisfy the core and cavity block movements so that we need to provide sliders

Bolts and Washers:

Provided Bolts and Washers for the Guides Provided in the core block

Ejector Pins:

Ejector pins are created for ejecting the components when the core block move away from the cavity block after the part solidified
