Description

Special sand box for V-process casting

Technical Field

The utility model relates to a sand box equipment technical field specifically is a special sand box of V method casting.

Background

In the process of casting production of castings, a casting sand box is generally used as a mold, and molten iron is poured into the casting sand box to cast castings required by users.

In a traditional sand box for casting, an upper box air suction pipe is formed by punching a square pipe and attaching a gauze screen to be directly welded above the sand box. This flask requires the position of the gates of the wood pattern relative to the flask. Sometimes, it is difficult to adjust the position of the feeder without interfering with the suction pipe of the flask because of the shape of the product. For heavy-digging counterweight products, the tonnage of sand inside the traditional sand box is large and the thickness is high after the sand falling, the suction force of the air suction pipe cannot meet the requirement, and the air pressure in the sand box is insufficient, so that the poured products are seriously deformed. When the air suction pipe is blocked or damaged, the whole gas flame is required to be cut to weld newly, the welding has higher requirements, and the waste is high.
