Week 8 - Challenge 6 - Core & Cavity Design

Core & Cavity Design

Create the Core and cavity blocks for the switch bezel designed in the earlier challenge.

Objective:-

Create the core and cavity Block in between the parting line and parting surface to make the moulding parts design

Mold creation Followed by steps :-

• Tooling axis
• Checking by draft analysis in Tooling direction
• Creating the parting line and parting surface
• Design of Core
• Design of Cavity

1. Tooling axis:-

Tooling axis is the axis in which core cavity open during completion of injection molding. To create the tooling axis, we need the proper orientation or view that gives the correct features and draft available in the component.

Component view from the Z direction gives the proper view for the tool to see the features present in the geometry. To create the tooling axis from the Z direction we need the tooling axis from the X direction since it gives the draft available at the slanted part.

The tooling axis created from the X Direction By the following Steps:

1. The class A surface is Extracted
2. Then the center point is created using the point, on the base surface at 0mm.
3. At the point axis system is created.
4. After switching the view of the model to the X direction and creating the tooling Axis.

Using the intersect in ZY plane to get the boundary lines.

Then the lines are created along the slant surfaces.

2.draft analysis in Tooling direction:-

Draft analysis enables you to detect the part we drafted will be easily removed. This type of analysis performed on the base of color ranges identifying the zones on the analyzed element where the deviation from the draft direction at any points, corresponds to specified values and direction

• Go to insert
• Click on the compass icon and align it with the tooling axis and click on the surface, we will get our result

3.Parting line and surface:-

Generally injection mold has two major components , the one movable half and another fixed halve, during injection molding process ,these halves are pressed tighting and form a sealed hallow to avoid the melt flow leakage and maintain certain holding pressure ,the pressed surface are called parting surface usually parting surface are biggest projection outlin of part

• Parting surface design principle:

Parting surface design directly Affects product Quality ,ease of construction and opertaion of injection Mold design one of the key factors to succes.

4. Design of Core :-

5 Design of Cavity:-

Core and cavity final :-

Conclusion: Thus i have design the core and cavity of the switch Bezel
