Week 12 Challenge

STEP1:

AS OF NOW, CORE, CAVITY , CLIDERS & WWASHERS ARE CREATED.

NOW WE HAVE TO CREATE EJECTOR SYSTEM. IT CONSISTS OF EJECTOR PINS & PLATES.

STANDARD EJECTOR PIN IS OF ø6mm.

NOW MAKE SOME EXTRUDE CUT FOR THE PROVISION OF EJECTOR PIN.

STEP2:

NOW CREATE EJECTOR PINS. USE EXTRUDE

STEP3:

PROVIDE RELIEF FOR EJECTOR PINS.

STEP4:

SINCE IT IS A CURVED PROFILE , WE HAVE TO CREATE D-SHAPED HEAD.

STEP5:

NEXT CREATE EJECTOR PLATE.

STEP6:

THEN CREATEHOLES ON THE EJECTOR TO ACCOMADATE EJECTOR PINS.

STEP7:

THEN CREATE EJECTOR BACK PLATE.

STEP8:

SO EJECTOR SYSTEM IS COMPLETED.

THEN IT IS TIME FOR RUNNER & GATE SYSTEM.

START WITH CAVITY BLOCK.

MAKE SOME EXTRUDE CUT FOR ALIGNMENT OF SPRUE.

STEP9:

CREATE SPURE. (IT IS OF STANDARD DIMENSION).

STEP10:

NOE JUMP TO CORE BLOCK.

MAKE SOME CUT TO ALLOW THE PLASTIC TO FLOW IN CORE BLOCK.

STEP11:

MAKE EXTRUDE TO MAKE RUNNERS. USE DRAFTS & FILLETS TO FORM THE PROFILE.

STEP12:

NOW DRAW THE ENTRY POINT ACCORDING TO REQUIRED AREA WHICH WILL BE GIVEN BY MOULD FLOW TEAM.

STEP13:

NOW USE COMBINE COMMAND TO MAKE THAT PROFILE ON CORE BLOCK.

STEP14:

RUNNERS & GATES ARE COMPLETED.

NOW CREATE AIR VENTS. MAKE TWO SMALLER CUTTERS IN CORE BLOCKS , SO THAT ONLY AIR CAN FLOW.

CREATE ON BOTH THE SIDES.

STEP15:

NOW CREATE COOLING SYSTEM. THREE THINGS TO CONSIDER HERE IS :

1) DIAMETER OF HOLE

2) DISTANCE BETWEEN TWO CONSCUTIVE HOLES

3) DIAMETER OF SOCKET HEAD.

SINCE THE COOLING SYSTEM DOESNOT REQUIRED FOR THIS MODEL.

IT IS REQUIRED , WE CAN CREATE COOLING SYSTEM IN CAVITY BLOCK ALSO.

NOW THE INJECTION MOULD FOR THE PLASTIC KNOB IS COMPLETED.
