Device for cleaning sand ejecting holes of mould for casting production line automatically

Abstract

The invention relates to a device for cleaning the sand ejecting holes of a mould for a casting production line automatically, comprising a gantry type bracket. The middle of the top of the bracket is provided with an air cylinder; the lower end of a piston rod is provided with a movable frame; the movable frame can move up and down in the bracket; the movable frame is a box type frame; punching heads which correspond to the sand ejecting holes on the mould are distributed uniformly on the outer side of the bottom surface of the movable frame, and a flat plate is arranged on the inner side of the bottom surface of the movable frame; two sides of the flat plate extend to the outside of the movable frame respectively; the inner two sides of the bracket are provided with a guiding rod respectively; each guiding rod is sleeved by a spring; the upper end of the each spring is connected with the upper part of each guiding rod, and the lower end is connected with one side of the flat plate; and a vibrating motor is fixed on the middle part of the flat plate. The device can be used for cleaning the sand ejecting holes of the mould quickly and automatically, thus convenience is brought to the next step of reejecting sand and moulding (coating sand in the mould) in the next step, the labor intensity of the operators is reduced significantly, the damage to the mould is decreased, and the casting production cost is lowered. The automatic cleaning device is easy to manufacture and convenient to debug.

Description

technical field [0001] The invention belongs to the technical field of casting production equipment, and in particular relates to an automatic cleaning device for sand shooting holes of molds in a casting production line. Background technique [0002] The casting molds on the production line are covered with sand by the sand shooting mechanism and then enter the casting process to cast the castings. After the castings solidify, they pass through the automatic turning device on the production line, and the castings are turned over and demoulded and dropped into the storage barrel. After the casting falls off, the residual sand layer on the mold must be cleaned before re-sand molding and circular casting. During the cleaning process, because the residual sand layer in the sand shot hole of the mold is thicker and the position is higher, the molten iron is not easy to collapse, so the cleaning is more difficult. The existing sand cleaning operation can only be cleaned by worke...
