Week 8 - Challenge 6 - Core & Cavity Design

AIM:

      To Create the Switch Bezel Plastic component through the given Class-A surface. To begin with, the tooling axis for the given Class-A Surface should be created meeting the requirements of the draft angle and at the end perform the Draft analysis on the model. 

Take the Thickness of the component to be 2.5 mm

       To Create the Core and Cavity for the Switch Bazel.

OBJECTIVE:

       Create the parting surface and parting line.

       Create Core and Cavity along the Tooling Axis.

       Use the publicatio option also.

INTRODUCTION:

       The control panel bezel is the frame part of the window switch that holds its switch covers and buttons into place. Moulding is the method used to manufacture the plastic trims of an automotive by most OEM’s, hence by considering the manufacturing consideration the switch bezel is designed.

      With draft analysis, you can verify draft angles, examine angle changes within a face, as well as locate parting lines, injection, and ejection surfaces in parts.

      Drafts are defined on molded parts to make them easier to remove from molds. There are two ways of determining the objects to draft: either by explicitly selecting the object or by selecting the neutral element, which makes the application detect the appropriate faces to use.

      To create the Geomatry set with proper name and sub geomatry set also.

 

       A positive draft means the angle of the face, with respect to the direction of pull, is more than the reference angle. Negative draft. Displays any faces with a negative draft, based on the reference draft angle you specified.

 

TOOLIN AXIS:

     

       The direction in which the mold or core and cavity opens is the tooling axis. Connectivity of Class-A surface: Checking the connectivity of the surface, this can be done by creating boundaries or by simply using the join option such that any openings can be easily visualized.

     

       Create the Tooling Axis by the Bisection method.

 

CREATE THE SOLID PART OF SWITCH BAZEL:

 

          To make the solid part from the Class A Surface by the Close view method.

 

          After creating closed surface create the solid part from the closed surface.

  

          Go to Part workbech click closed view and select the surface.

 

 

DRAFT ANALYSIS:

 

       Check the Draft angle of the Solid Part.

 

    The Red zone need's Side core or Check with 1.4 angle it will negligable.

 

CREATE THE CORE AND CAVITY:

 

    Create the New Geometrical set and name it core and cavity.

 

    First create the core block by the close view method along with Tooling Axis.

 

Make it solid by the Close view command.

 

 

CAVITY PART:

 

   Create the cavity like wise the Core part.
