Description

Sand material recovery system for casting mold

Technical Field

The utility model relates to a casting technical field especially relates to a casting die sand material recovery system.

Background

In casting, firstly, a product to be produced is made into a 'wooden product', generally called a 'wood pattern', and then the wood pattern is put into special sand, the sand is generally arranged in a sand box, generally comprising an upper sand box and a lower sand box, the wood pattern is put between the two sand boxes, and the periphery of the sand box is filled with sand and compacted. Then. The two sandboxes are separated and the wooden mold is removed from the sand. The removal of the wooden pattern from the sand is called stripping. After taking out, a space which is completely the same as the product shape is left, then the molten metal liquid is poured in, and after cooling, a metal product is formed.

When the large-scale casting die is drawn, a mechanical device is generally adopted to separate an upper die from a lower die, sand can partially fall out due to the large vibration amplitude during drawing, on one hand, the production environment is poor, the normal work of workers is influenced, and on the other hand, the workers fall down due to the serious condition, so that the potential safety hazard is realized, the sand pollution on the other hand cannot be repeatedly utilized, and the production cost is high.
