Week 8 - Challenge 5 - Core & Cavity Design

AIM:

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

PROCEDURE:

Core

• The core has been created from the rectangular sketch that created, it will be extruded to some height.
• Then by using B surface it will be trimmed with respect to the extruded surface.
• On the above the boundary line will be created, using that boundary line it will be filled on the top.
• Then it will be joined with the filled surface and the extruded surface.
• After that there wont be any open area.
• So that it can be changed into closed part.

Cavity

• The cavity has been created from the rectangular sketch that created, it will be extruded to some height.
• Then by using B surface it will be trimmed with respect to the extruded surface.
• On the bottom the boundary line will be created, using that boundary line it will be filled on the below.
• Then it will be joined with the filled surface and the extruded surface.
• After that there wont be any open area.
• So that it can be changed into closed part.

Component

• It is a switch bezel closed part that is done in surface modelling.
• By using A,B and C surface the switch bezel component will be created in between the core and cavity.
• This switch bezel component will be projected in the core side.

Parting surface

• It is the surface that is inbetween core and cavity, this surface that seperates the core and cavity.
• It is a imaginary surface that is not in real.
• That surface will be in the same shape as component.

Parting line

• It is the boundary line of the component.
• This can be in the edge of B surface.
• This parting line indicates the size of the component.
• And that parting line seprates the component and parting surface

Core & Cavity design

• The complete Core and cavity block of Switch bezel is shown below.
• The Tooling axis of this design is placed in the core and cavity block.
• the space inside the core and cavity the hot mold will flow inside.
• Then it gets shape accordong to shape that is alreday there in the core side.

RESULT:

Hence the Core and cavity Design has been created on the Switch bezel.
