Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to an automatic casting disassembly device for taking out convex solidified castings from a sand mold, removing burrs and burrs, and removing sand.

(b) Conventional technology Automatic casting equipment that automatically sequentially forms a mold, pours metal into the mold, and separates the casting and sand mold from the flask on a conveyor is known in the art (for example, Utility Model Application No. 1771). In this conventionally known automatic casting device, the casting solidified in the sand mold is transported while leaving the mold flask on the conveyor.
The sand mold and the top were pushed down onto the pallet on the conveyor installed below (the temperature of the casting at this point was 700-800℃).
00°C), the castings mixed with the sand from the sand mold thrown onto the pallet are removed by workers placed along the conveyor, and are removed by lifting, breaking with a burr hammer, etc.
Sand separation is being carried out.

(c) Problems to be Solved by the Invention The above-mentioned casting disassembly process in the conventionally known automatic casting apparatus has an extremely poor working environment due to its nature, is completely manual work and is therefore inefficient, and also involves high-temperature castings. Since the core sand is left in contact with the foundry sand for a long period of time, the core sand is baked too much, which has the disadvantage of accelerating the deterioration of the foundry sand. The present invention aims at eliminating or reducing the above-mentioned drawbacks.
