Abstract

The invention relates to the technical field of mechanical casting tool devices, and particularly relates to a molding sand dispersing and screening device for mechanical casting. According to the molding sand dispersing and screening device for mechanical casting, the electric push rod stretches out and draws back to drive the hopper to move, and the discharging position of the discharging pipe is changed; meanwhile, a discharging assembly is arranged, a first gear moves along with a hopper and is meshed with a fixed rack so that a connecting shaft is driven to drive a rotating disc to rotate, therefore, along with rotation of the rotating disc, a through hole and an outlet in the bottom end of a discharging pipe intermittently coincide, discharging is achieved, and therefore molding sand falls on a screen in a dispersed mode and is prevented from being accumulated at a certain position of the screen in a concentrated mode; in addition, based on transmission, through movement of the hopper and cooperation of a pull rope, a rack, a gear and the like, a cam below the screen rotates and acts on the screen, the screen vibrates up and down, and therefore screening is accelerated.

Description

technical field [0001] The invention relates to the technical field of mechanical casting equipment, and relates to a molding sand dispersion and screening device for mechanical casting. Background technique [0002] Casting is a method of manufacturing metal castings with a certain shape and performance requirements obtained by pouring, injecting or sucking high-temperature molten liquid metal into the mold cavity, and waiting for it to solidify. Casting production belongs to thermal processing, and its production process includes: sand mixing, molding, melting, pouring and cleaning. [0003] Common mold materials are raw sand, clay, water glass, resin and other auxiliary materials. For sand materials such as raw sand, screening is required. However, the feeding position of the molding sand in the existing device is fixed, so it is easy to concentrate and accumulate in a certain place of the screen, resulting in the problem of low screening efficiency. [0004] Therefore...
