Week 8 - Challenge 6 - Core & Cavity Design

AIM: TO CREATE CORE AND CAVITY BLOCKS FOR THE GIVEN SWITCH BEZEL CLASS A SURFACE

CLASS A:

THE GIVEN CLASS A SURFACE

TOOLING AXIS:

IN ORDER TO PERFORM CORE AND CAVITY WE NEED TO CREATE TOOLING AXIS FOR DRAFTING ANALYSIS ,

RESPECTED TO CLASS A SURFACE THE BOTTOM IS SELECTED AND EXTRACTED AND CREATED A MIDPOINT ON THE SURFACE AND WITH HELP OF THE POINT 2 SKETCH ARE CREATED

IN TWO SKETCH TWO LINES ARE GOING IN Y DIRECTION

SKETCH 1 AND SKETCH 2 ARE SELCTED AND A NEW BISCET LINE IS CREATED AND ITS NAMED AS TOOLING AXIS

DRAFTING ANALYSIS:

ONCE THE TOOLING AXIS IS CREATED IT IS READY FOR DRAFT ANALYSIS

CLICK ON THE DRAFT ANALYSIS ICON

AND SELECT THE COMPASS MOVE TOWARDS THE TOOLING AXIS AND LOCK AND CLICK ON THE SURFACE OF CLASS A DRAFTING ANALYSIS IS DONE

CLASS B AND CLASS C SURFACE:

AFTER DRAFT ANALYSIS CREATION OF CLASS B AND C

EXTRACT

UNTRIM

EXTRAPOLATION

WITH THESE COMMANDS THE CLASS A SURFACE IS SELECTED AND THE CREATION OF CLASS B IS DONE ONCE THE CLASS B IS DONE WITH HELP OF CLASS A AND CLASS B

IT IS JOINED INTO A SINGLE SURFACE AND WITH HELP OF SWEEP COMMAND AND TOOLING AXIS WITH DRAFT ANGLE OF 3 DEGREE

CLASS C SURFACE IS CREATED WITH TOOLING AXIS

PART CLOSE SURFACE:

ONCE THE CLASS C IS DONE WE ARE MOVING TO THE PART DESIGN AND USING CLOSE SURFACE COMMAND IT BE BEEN CLOSED AND PART MODEL IS CREATED

DRAFT ANALYSIS OF PART SURFACE:

CLICK ON THE DRAFT ANALYSIS ICON

AND SELECT THE COMPASS MOVE TOWARDS THE TOOLING AXIS AND LOCK AND CLICK ON THE SURFACE OF PART AND DRAFTING ANALYSIS IS DONE WITH RESPECTIVE DEGREE OF 3

AND IT IS CHECKED IN ALL SIDES OF THE DESIGN

ONCE IT IS CHECKED ITS MOVED FOR CORE AND CAVITY DEISGN

PARTING SURFACE:

TO DESIGN THE INJECTION MOLD STRUCTURE AS SIMPLE AS POSSIBLE, TO AVIOD OR REDUCE SIDE PARTING AS MUCH AS POSSIBLE TO REDUCE THE COMPLEXITY OF MOULD MAKING

TO ENSURE TH DIMENSIONAL ACCURACY OF THE MOLDED PARTS , TRY TO MAKE PARTS WITH SIMILAR DIMENSIONSAL ACCURACY REQUIREMENTS IN THE SAME MODULE TO REDUCE MANUFACTURING AND ASSEMBLY ERROS

CREATION OF PARTING LINE

WITH BOUNDARY COMMAND THE CLASS A SURFACE IS SELCTED AND BOUNDARY IS TAKEN

AND ITS IS EXTRAPOLATED WITH RESPECITVE OF 15mm

AND IT IS JOINED WITH THE CLASS A AND C

ONCE ITS IS DONE WITH INTRESCTION CLASS A , CLASS B AND AND THE JOINED SURFACE IS SELECTED AND WITH INTERSECTION COMMAND

PARTING SURFACE IS CREATED

CAVITY:

A RECTANGLE SKETCH IS DRAWN IN THE AXIS SYSTEM OF XY PLANE

IT IS EXTRUDED

AND IT IS TRIMMED ALONG THE CLASS B SURFACE

AND WITH THE HELO OF FILL COMMAND IT SIS CLOSED AND IT IS JOINED WITH THE CAVITY

CORE:

WITH RESPECTIVE SAME RECTANGLE SKETCH AGIAN IT IS EXTRUDED AND TRIMMED ALONG THE PARTING SURFACE WITH COMPONENT

ONCE IT IS DONE ITS BEEN FILLED AND JOINED WITH THE CORE SURFACE

PARTING LINE:

AFTER CORE AND CAVITY DESIGN IS DONE THE PARTING LINE IS CREATED WITH THE CLASS B AND JOIN OF CLASS A AND C SURFACE IS CHOOSED

WITH INTERSECTION COMMAND THE BOUNDARY IS TAKEN AND THE PARTING LINE IS CREATED

CORE AND CAVITY PART DESIGN:

CORE AND CAVITY IS SELECTED A NEW BODY IS CREATED ALONG TREE STRUCTURE

AND PART DESIGN MODE IS CHOOSED AND BOTH THE CORE AND CAVITY IS BEEN CLOSED USING CLOSE SURFACE COMMAND

WITH HELP OF TRANSLATE BOTH CORE AND CAVITY ARE TRANSLATED FOR A DISTANCE OF 50mm
