Discharging structure and material distributing system

Abstract

The invention discloses a discharging structure and a material distributing system. The discharging structure comprises an inner-layer cover body, a middle-layer cover body and an outer-layer cover body, wherein the inner-layer cover body is used for at least covering a casting opening of a mold, the inner-layer cover body is sleeved with the middle-layer cover body, a first function channel is formed between the middle-layer cover body and the inner-layer cover body, the middle-layer cover body is sleeved with the outer-layer cover body, a second functional channel is formed between the outer-layer cover body and the middle-layer cover body, one of the first functional channel and the second functional channel is a discharging channel, and the other one is a dust collection channel. The inner-layer cover body is sleeved with the middle-layer cover body, and the middle-layer cover body is sleeved with the outer-layer cover body, so that ball sand can be evenly distributed around a mold when entering a heat preservation box, the situation that the ball sand is not evenly distributed is avoided; when one of the first functional channel and the second functional channel serves as the discharging channel for discharging the ball sand, the other one serves as the dust collection channel, so that flying dust generated in the process that the ball sand enters the heat preservation box is pumped away, sweeping work can be greatly reduced, and dust pollution can be reduced.

Description

technical field [0001] The invention relates to the technical field of casting equipment, in particular to a discharge structure and a material distribution system. Background technique [0002] When the casting mold is buried, it is necessary to place a sand mold in an incubator, and fill sand and balls around the mold for vibration. When burying the mold, put the heat preservation box with the sand mold under the silo to connect sand and balls to bury the mold. Since the sand mold is placed in the insulation box, the insulation sand and balls will accumulate in the middle when they are placed in the insulation box, and cannot be evenly distributed around the sand mold. Every time a part of the sand and balls are placed, the sand and balls must be manually spread around the insulation box. , low work efficiency. And because the height of the incubator is different, the sand and balls fall directly from a high place onto the plate covering the sand mold in the middle of th...
