Week 8 - Challenge 1 - Base Bracket Design

DRAFT ANALYSIS OF BASE BRACKET AND THE CLASS A SURFACE AND CREATING A BASE BRACKET FROM GIVEN CLASS A SURFACE

GIVEN CLASS A SURFACE

DRAFTING

WHILE PRODUCING A PLASATIC COMPONENT IN THE INJECTION MOULDING . IT BECOME VERY NECESSARY TO GIVE DRAFT (TO MAKE TAPER ) TO PROVIDE EASY EJECTION OF THE FINAL MOULDED PRODUCT FROM THE MOULDING MACHINE . IF IT IS NOT DONE WHILE MOULDING OF THE PRODUCT THE MOULDED PRODUCT SHRINKS AND TRY TO STICK TO THE WALL OF THE MOULD . AND THAT RESULT IN THE BAD FINISHING OF THE PRODUCT THAT LOOKS UGLY . AND ALSO IT BECOMES VERY DIFFICULT TO EJECT THE PRODUCT. USUALLY WE GIVE 0.5 TO 3 DEGEE OF DRAFT TO THE PLASTIC COMPONENT IN THE AUTOMOTIVE INDUSTRY.

DRAF ANALYSIS

DRAFTING ANALYSIS IS THE TOOL BY WHICH WE CHECK THE DRAFT OF THE SURFACES OF THE PRODUCT . IF IT WILL CLEAR THE TOOLING AXIS . IT IS SHOWN BY THE RANGE OF COLORS (GREEN,RED,BLUE).THAT ARE SHOWN BELOW.

CREATION OF THE TOOLING AXIS

PROCEDURE

(A) FIRST WE CREATE A DUMMY TOOLING AXIS

(B) AFTER THAT WE MAKE A INTERSECT OF THE CLASS A SURFACE AND THE YZ PLANE .

(C) THEN WE CHECK THE SURFACE WHICH CAN MAKE A TROUBLE DURING THE EJECTION OF THE PRODUCT . THAT IS PARALLEL TO THE TOOLING AXIS . AND MAKE LINE ON THAT POINTS

(D) AFTER THAT WE MAKE A LINE BISECTING BOTH OF THE LINES .

(E) THIS IS THE REQUIRED TOOLING AXIS .
