Novel shakeout machine

Abstract

The invention discloses a novel shakeout machine comprising a rack, a shakeout device, a molding sand recovering device, a power unit, a noise reduction and dust removal device and a casting collecting device, wherein the rack is a rectangular box body; the shakeout device is mounted in the rack and is composed of a vibrating screen plate, a shakeout grate bed and a supporting rod, wherein the vibrating screen plate is located above the shakeout grate bed and is connected with the shakeout grate bed through the supporting rod, and the bottom of the shakeout grate bed is provided with a spring mounted on the rack; the power unit is mounted in the rack and is provided with a vibrating motor; a hole is formed in a central position at the bottom of the shakeout grate bed; an eccentric shaft is mounted in the hole, and a reduction gearbox is provided to be connected with the eccentric shaft and is connected with the vibrating motor; and the molding sand recovering device is mounted on the rack located below the shakeout device. The novel shakeout machine is obvious in molding sand and casting separation effect, timely in molding sand recovery and low in noise and pollution in the separation process.

Description

technical field [0001] The invention belongs to the field of foundry machinery, in particular to a novel shakeout machine. Background technique [0002] The shakeout machine is a casting equipment that uses vibration and impact to separate the sand in the mold from the casting. The structural characteristics of the inertial shakeout machine commonly used in my country are: the shakeout grid bed is equipped with a rotating shaft with a heavy weight, and when the shaft rotates, it is heavy Centrifugal force (exciting force) is generated to vibrate the shakeout grid bed installed on the support spring. In actual production, the shakeout machine is noisy, the pollution is serious, and the separation effect of the molding sand and the casting is not obvious. Contents of the invention [0003] The object of the present invention is to provide a new type of shakeout machine, which has obvious separation effect between molding sand and castings, low noise and less pollution.
