Cleaning device for box surface of sand box

Abstract

The invention relates to a cleaning device for the box surface of a sand box, comprising an arch-shaped mounting bracket and a door-curtain type strip brush mounted on the bracket. By the arch bracket provided with the trip brush, the device cleans sands left on the box surface of the sand box when a sand mould passes through an arch, and solves the problem that the floating sands on the box surface of the sand box are not cleaned before molding.

Description

technical field [0001] The invention relates to a device for cleaning residual molding sand on the surface of a sand box in casting molding production. Background technique [0002] In the automatic production line of casting molding, before entering the sand shakeout process, the molding sand sand box will be poked, and the sand will be easily brought to the surface of the sand box after the box poking machine finishes poking the box. Because the sand box It needs to be recycled in production, so if the cleaning is not clean, the sand will be pressed on the surface of the sand box during the next molding, which will cause the upper and lower sand box surfaces to fail to close when the molding is closed. The consequence is that it will occur during pouring Castings are scrapped due to leakage of molten iron and misalignment of sandboxes. Correspondingly, the scrap rate is increased, the production cost is increased, and the casting quality is affected at the same time. Co...
