Problems solved by technology

High collapsibility, also known as sand production, that is, whether the molding sand is easy to break after the casting is solidified, and whether it is easy to remove from the casting. In the prior art, there are many defects in the mixing equipment of the molding sand, resulting in poor quality of the molding sand

Abstract

The invention discloses a foundry molding sand processing and feeding device which comprises supporting legs and a feeding rack, wherein the feeding rack is fixedly arranged on the supporting legs; a chassis is arranged on one side of the feeding rack; a stirrer is fixedly arranged on the chassis; an additive adding opening and a feeding hole are formed in the side wall of the stirrer; a hopper is arranged on the feeding rack in a sliding mode; and the hopper is driven to move up and down by virtue of a motor which is fixedly arranged at the upper end of the feeding rack. The device disclosed by the invention is simple in structure, high in feeding speed, and uniform in stirring, and molding sand is good in processing quality.

Description

technical field [0001] The invention belongs to the field of smelting alloy casting, and relates to a molding sand feeding device, in particular to a casting molding sand processing feeding device. Background technique [0002] The role of molding sand in foundry production is extremely important, and the casting waste caused by poor quality of molding sand accounts for about 30-50% of the total casting waste. The requirements for good quality molding sand are: high strength and thermal stability to withstand various external forces and high temperatures. Good fluidity, that is, the ability of molding sand to move between sand particles under the action of external force or its own gravity. Certain plasticity, that is, the ability of molding sand to deform under the action of external force and maintain the given shape when the external force is removed. Better air permeability, that is, the ability of the pores of the molding sand to pass through the gas. High collaps...
