DESIGN OF SWITCH BEZEL AND ITS CORE AND CAVITY

AIM:-DESIGN OF SWITCH BEZEL AND ITS CORE AND CAVITY

EXPLAINATION:-

TOOLING AXIS

In this plastic component tooling axis has been created by using compass method.

Compass is brought to the surface and placed anywhere on the surface.
Now by moving compass we check that all surface are gree or not.
If so we lock the compass direction by right clicking on compass and use lock direction option.
Now create point on surface and create a line using point-direction.
Using point as referance and compass direction as direction.
We get a line that is our tooling axis.

CREATION OF PLASTIC COMPONENT:-

All the surfaces are extracted from class A surface.
untrim all the surface and extrapolate them using point-continuty and curvature.
Now offset the surface by thickness of 2.5mm which is the thickness of the component.
Now trim the surface. Here we get class B surface.
Now addition of fillets are done which is (14-2.5)mm.
Now insert new geometrical set for class C surface and we take boundary of class A surface.
Now we do sweep using drafting option taking tooling axis as direction and giving draft angle of 3degree.
Now join class C and class A surface .
And trim new join with class B surface.
Here we get our plastic component.
Insert new part body and open part workbench and convert plastic component into closed body.

DRAFT ANALYSIS VIEW OF CLASS A SURFACE

DRAFT ANALYSIS OF SWITCH BEZEL PART BODY

NOW WE WILL DESIGN CORE AND CAVITY

We have already created switch bezel component.
Now we will design core and cavity for switch bezel.
Now we perform multiple extract to class A surface.
And unhide class C surface and trim them.
Now unhide class B surface and trim them with the previous trim and this can be called as parting surface.
Draw a rectangle of any dimension but it sholud lie inside the parting surface.
Now extrude the rectangle to some extand and trim with parting surface.
