Description of green sand mixer:

When large number of castings is to be produced, hand moulding consumes more time, labour and also accuracy and uniformity in moulding varies. To overcome this difficulty, machines are used for moulding.  Jolt Squeeze molding machine is economic molding solution for manual and simply automatic clay sand casting production. Jolt squeeze molding machine do not need big floor space. And it is flexible to increase molding machines when casting production increasing.

Jolt squeeze moulding machine combines the operating principles of ‘jolt’ and ‘squeeze’ machines resulting in uniform ramming of the sand in all portions of the moulds

• The machine makes use of a match plate pattern placed between the cope and the drag box. • The whole assembly is placed on the table with the drag box on it.

• The table is actuated by two pistons in air cylinders, one inside the other. One piston called ‘Jolt piston’ raises and drops the table repeatedly for a predetermined number of times, while the other piston called ‘squeeze piston’ pushes the table upward to squeeze the sand in the flask against the squeeze plate. In operation, sand is filled in the drag box and jolted repeatedly by operating the jolt piston.

• After jolting, the complete mould assembly is rolled over by hand.

• The cope is filled with sand & by operating the squeeze piston, the mould assembly is raised against the squeeze plate. By the end of this operation, the sand in the mould box is uniformly packed.

• The match plate is now vibrated and removed. The mould is finished and made ready for pouring.
