F-shaped molding production line, F-shaped molding production method and V technique casting method

Abstract

The invention discloses an F-shaped molding production line, an F-shaped molding production method and a V technique casting method. The F-shaped molding production line comprises a first guide rail,and a first roller bed, a second roller bed, an empty case roller bed, a drenching sand adding device and a film removal table which are sequentially arranged along the extension direction of the first guide rail, wherein a first trolley which can move along the first guide rail is arranged on the first guide rail in matching mode, the first trolley carries a first vibrating compaction table, thefirst vibrating compaction table is used for receiving upper negative pressure cases conveyed on the first roller bed or the second roller bed, and drives the upper negative pressure cases to sequentially pass through the empty case roller bed and the drenching sand adding device correspondingly for empty box inverting and sand adding, and finally the upper negative pressure cases are conveyed tothe film removal table. By adopting the mode of arranging two guide rails and matching two roller beds with each guide rail, the effects that one V technique molding line can simultaneously produce two types of castings, waiting time of the vibrating compaction table is fully used, improvement of work efficiency of each component can be realized, and overall molding time is reduced are achieved.

Description

technical field [0001] The invention belongs to the field of V-method casting, and in particular relates to an F-shaped molding production line, a production method and a V-method casting method. Background technique [0002] The V method process is a new technology used to produce castings. It uses anhydrous and binder-free molding sand. The inside of the cavity, the top and the bottom of the sand box are covered with a layer of plastic film. The molding sand in the sand mold is passed through The air in it is drawn out by a vacuum device, and is tightly combined under the action of air pressure to form a cavity with the same shape as the mold, and the molten metal is poured into the cavity to obtain a special casting method for castings. [0003] The inventor found that in the V-method casting production line, which is usually a straight molding line, the moving vibrating table drives a negative pressure box to perform film covering, box buckling, sanding, vibrating leveli...

Problems solved by technology

[0003] The inventor found that in the V-method casting production line, which is usually a straight molding line, the moving vibrating table drives a negative pressure box to perform film covering, box buckling, sanding, vibrating leveling, and mold taking and box closing in sequence. , the mobile vibrating table needs to return with the mold to carry out film coating, the mobile vibrating table wastes a lot of waiting time in the whole process, and the production capacity of each component is not fully utilized; in addition, each molding line can only produce one casting at the same time , when another casting needs to be produced, the mold and negative pressure box need to be replaced, which also wastes a lot of time and reduces the efficiency of V-method casting
