Sand mold casting sand screening machine

Abstract

The invention relates to a sand mold casting sand screening machine. The sand mold casting sand screening machine comprises an inner screening barrel and an outer barrel; the outer barrel is arrangedon the outer side of the inner screening barrel; a control panel is arranged on the side face of the outer barrel; front supporting legs and rear supporting legs are arranged below the outer barrel; the front supporting legs are each composed of a piston rod and a hydraulic cylinder; the rear supporting legs are both hinged to the bottom of the outer barrel; a sand outlet is formed below the outerbarrel, and is provided with a sand baffle; a sand collecting groove is arranged below the sand baffle; a feeding port is welded in front of the inner screening barrel; an electromagnetic valve is arranged at the junction of the feeding port and the inner screening barrel; a motor is arranged below the feeding port, and is connected with a rotating shaft which is provided with a stirring paddle;inner splines are arranged in front of and behind the rotating shaft; outer splines used in cooperation with the inner splines are arranged in front of and behind the inner screening barrel; bearingsare arranged in front of and behind the outer barrel; and a waste material port is formed below the inner screening barrel. The sand mold casting sand screening machine has advantages of being simpleand practical in structure, high in automation degree and capable of smashing raw materials and saving cost.

Description

technical field [0001] The invention belongs to the technical field of casting, and in particular relates to a sand screening machine for sand casting. Background technique [0002] Because the molding materials used in sand casting are cheap and easy to obtain, the casting mold is easy to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings. It has been the basic process in casting production for a long time; sand casting has Sand mixing and sand sieving, among which sand sieving is mainly to remove impurities such as scrap iron, agglomerated sand and other things to keep the sand even and clean when the old sand is reused; at present, many small and medium-sized enterprises use manual sand sieving, Not only the efficiency is low like this, but also the screening effect is not good; therefore, a kind of sand casting sand screening machine is needed.
