Title: Making a sand mould with the pattern developed earlier byperforming sand mould making operations.

Aim: To gather knowledge regarding different mould making tools, gating system design, core making and green sandmoulding

Raw Materials: The pattern developed earlier as per drawing, Green Sand,Bentonite Powder, Coal Dust, Yellow Dextrin, Facing Sand,Parting Sand, French chalk and Water.


1. Riddle2. Shovel3. Moulding Board4. Moulding Flask (Cope and Drag parts)5. Rammer6. Strike off Bar7. Bellow8. Sprue Pin9. Riser Pin

10. Vent Rod11. Draw Spike12. Gate Cutter13. Lifter14. Slick15. Trowels16. Cleaning Brush17. Water Mug

Procedure:1. Green sand for moulding is prepared by mixing Silica sand with 8-12% bentonite

and 2-3% water. To improve bonding strength, 5-6% coal dust and 2-3% yellowdextrin are added as additives. All mixing is done with the help of shovel.

2. Then the prepared green sand is screened by Riddle fitted with coarse andmedium mesh size wire mesh in order to remove the impurities. During thisprocess to avoid dryness of the green sand suitable amount of water is added.

3. Drag part of the moulding flask is placed on the moulding board. The half portionof the given Split Pattern is placed at a convenient position within the mouldingflask keeping space around all the sides. Facing sand is sprinkled over the boardand pattern. Then the box is filled with the prepared green sand by using shovel.





18

4. During filling the green sand is rammed properly with the Rammer to facilitatethe adherence of the sand to the surfaces of the box.

5. Upper surface of the drag box is smoothened and leveled with the edges of thedrag box by removing excess sand by using the Strike- off Bar.

6. Then by using a Vent Rod, small holes are created in the rammed sand forproviding paths for removal of gases.

7. Then another moulding board is placed on the drag box and the box is turnupside down with bottom board.

8. Then the upper board is removed and the upper surface is cleaned by removingloose sand particles by blowing air by using Bellow

9. Then parting sand is sprinkled over the cleaned upper surface.10. Then the other half portion of the Pattern is placed on the first half portion of the

Pattern already fitted in the drag box.11. Then the Cope part of the moulding flask is placed properly on the drag part.

Sprue pin and Riser pin is placed at proper place for forming the sprue and riser.12. Then the cope box is also filled with green sand in a similar way like the drag box

(Step 3-6).13. Then Sprue and Riser Pin are removed carefully. Then a funnel shaped hole

(called pouring basin/cup) is made at the top of the Sprue hole.14. Then the cope is separated from the drag and any loose sand on the cope and drag

interface of the drag is blown off with the help of bellow.

15. Then the cope and drag pattern halves are withdrawn by using Draw Spike aftershaking properly.

16. Then the defective part, if any, of the mould is properly repaired with the help ofslick and lifter.

17. Then water is gently spread over the repaired portion and the portions adjacent tothe pattern of the mould carefully without damaging the mould

18. Then using Gate Cutter, gates and runners are cut in the drag part of the mould.19. Then any excess or loose sand in the runners and mould are lifted up by lifter and

then blown off by Bellow.

20. Then French chalk dust is spread all over the mould cavity and runners.21. Then the cope part is placed on the drag part taking care of the alignment of thetwo by means the pins.

Thus the sand mould for a pattern is made, which is ready for pouring the moltenmetal .

Precautions:

1. Ramming should be done properly to get the required rigidity of the sand mould. 2. Care should be taken during removal of pattern, sprue and riser pins so that any

portion of the mould is not damaged during removal.

extent the melting if required.

9.

When melting is complete then remove lid, scoop off slag, which is floating ontop, with a slotted steel spoon and turn off the furnace.10. Take out the crucible with the help of flat tong.





20

11. Then Pour the molten metal into the pouring basin and metal flow into themould cavity through gate via sprue and runners.

12. Pouring is continued till riser is filled up with molten metal.13. Wait for a considerable time of at least 1 hr for solidification of molten metal

within the mould cavity.14. Then crush the mould and taking out the casting.15. After that necessary fettling operation, that is removal of gates, riser and other

unnecessary projections by using hacksaw blade and cleaning of the surfaces bygrinding, is performed.

16. Checking of final dimensions by steel rule and vernier caliper according todrawing.
