Vibrating iron-type sand shooting vent cleaning device and method

Abstract

The invention relates to a vibrating iron-type sand shooting vent cleaning device and method, and belongs to the field of iron-type sand casting equipment. The device comprises an ejecting cylinder, an iron-type conveying roller bed, an iron-type positioning device, a machine frame, an ejecting movable beam, an ejecting rod plate, an iron-type supporting base and a vibrating mechanism, wherein the ejecting cylinder is installed on an upper beam of the machine frame, the ejecting movable beam is fixed to a piston rod of the ejecting cylinder, the ejecting rod plate is provided with ejecting rods, the ejecting rods are fixed to the ejecting movable beam, the position and the number of the ejecting rods on the ejecting rod plate are matched with those of upper iron-type sand shooting vents, the iron-type supporting base is installed on the machine frame, the vibrating mechanism and the iron-type conveying roller bed are both fixed to the ejecting movable beam, and the iron-type positioning device is fixed to the iron-type conveying roller bed. According to the device and method, residual sand in the iron-type sand shooting vents can be conveniently ejected out, vibration force transmitted by the ejecting rods can assist in cleaning residual sand layers in an iron-type inner cavity, energy is saved, and requirements of large-scale iron-type sand casting production are met.

Description

technical field [0001] The invention relates to a device and a method, in particular to a device and method for cleaning iron mold sand shooting holes with vibration, which belongs to the field of iron mold sand-coated casting equipment. Background technique [0002] Sand-coated iron casting is one of the special castings, which is an energy-saving and material-saving casting production method. In the production process of sand-coated iron mold casting, the sand-coated layer on the iron mold is to cover the inner cavity of the iron mold with the sand-coated sand through the sand shooting holes of the iron mold through the sand shooting molding machine. The arrangement of the sand shooting holes must meet the The complete sand-covering requirement of the entire sand-covered casting mold, the more complex the mold switch, the more sand-shot holes and the number of the iron mold, the greater the difference in the height of the cavity in the mold, and the greater the size gap be...

AI Technical Summary

Problems solved by technology

Although this patent conveniently and efficiently removes the sand-covered sand hole of the iron mold and the residual sand in the inner cavity, so as to meet the production requirements of iron mold sand-covered casting, it requires a large ejection force to eject the sand-coated sand in the sand-shot hole. Moreover, the residual sand in the inner cavity of the iron mold needs to be activated to be vibrated and separated from the iron mold. The power is high and the strength is high, which wastes energy, so it still has the above-mentioned defects.
