Automatic sand discharging device and sand discharging method thereof

Abstract

The invention discloses an automatic sand discharging device and a sand discharging method thereof. The automatic sand discharging device comprises a sand storage hopper used for storing molding sand, a sand box used for product modeling, and a modeling table used for fixing the sand box. The automatic sand discharging device further comprises a control mechanism used for controlling the integral operation of the device, a sand conveying mechanism which is arranged below the sand storage hopper and used for conveying the molding sand, and a sand discharging mechanism which is arranged above the sand box and used for discharging the sand. The sand discharging mechanism is arranged below the sand conveying mechanism and matched with the sand conveying mechanism. The sand conveying mechanism is hung below the sand storage hopper through a hanging assembly and matched with the sand storage hopper. The sand discharging mechanism is fixedly connected with the sand storage hopper. By means of the automatic sand discharging device and the sand discharging method thereof, the production efficiency and yield are improved; meanwhile, the sand discharging amount can be accurately adjusted and controlled every time of processing, the molding sand is effectively prevented from being wasted, and the production cost is reduced.

Description

technical field [0001] The invention relates to an automatic sand-discharging device and a sand-discharging method thereof, in particular to an automatic sand-discharging device suitable for molding thin-walled small parts, and belongs to the field of metallurgical tooling. Background technique [0002] The automatic sand release device is a device used for casting production and molding sand release. Its working principle is to put a certain amount of molding sand into the sand box with the help of this device to fill the sand box. After the molding sand in the mold is compacted, the mold is ejected to form a cavity of a specific shape, that is, the cavity described in the processing process, and the molding is completed. Then melt the molten metal, pour the molten metal into the completed cavity, and wait for the molten metal to cool and solidify to form a casting. [0003] Existing automatic sand release devices mostly adopt a rough sand release method, but this sand rel...

AI Technical Summary

Problems solved by technology

First, in this invention, the quantification and placement of the molding sand are all completed through the sand bucket, and the adjustment of the amount of molding sand is only completed by adjusting the stroke of the cylinder. In the actual production and processing process, the error is relatively large. Second, the invention The technical solution in is actually a labor-intensive structure. The sand bucket is always under the downward pressure from the upper molding sand. Due to the high quality of the molding sand, the sand bucket is prone to stress fatigue during the use of this invention. , resulting in excessive sand release and affecting the processing effect
