Week 8 - Challenge 5 - Core & Cavity Design

CREATION OF DRAFT ANALYSIS , CORE AND CAVITY DESIGN OF SWITCH BEZEL

1.DRAFT ANALYSIS

• the solid body is drafty analysed using the main tooling axis

2.CORE AND CAVITY

PARTING LINE:

• it is the line where the core and cavity closes and the parting line is always kept on the b side to ensute the asthetic outer remain undisturbed by the tooling
• because while core and cavity closes the molten plastic escaped through the parting line and it needs further cutting and when it is in the b side cutting may not be required eventhough the cutting is made the asthetic appearance of the product is not afferted

CORE:

• this is the above block which usually have protrution to compress the platic and it moves up and down
• here first a rectangle intesecting the class b outer body is created and
• for core the class a class c joined and class b is trimmed in other direction
• finally the rectangel is trimmed and the open phase is filled
• then finally the closed surface is made solid by closed body

CAVITY

• this is the depression phase where the block has the depression of the class b
• same procedure as core but here the rectrangle is trimmed with the b class alone and the open phase is filled
• then finally the closed surface is created into body by using the closed body option
