Problems solved by technology

[0003] In the current production, the sand mold is generally broken manually to take out the poured castings. On the one hand, manual breaking is prone to uneven force, and it is easy to break the castings in the sand mold, resulting in a high scrap rate. On the one hand, manual crushing consumes a lot of manpower, and the production efficiency is low

Abstract

The invention discloses a sand package unpacking machine. A sand package comprises a casting and a sand mold wrapping the outer side of the casting. The casting has first perpendicular projection projected on the horizontal plane, and the sand mold has second perpendicular projection projected on the horizontal plane. The unpacking machine comprises a base, a carrying mould arranged on the base, an ejecting plate arranged above the base, and an unpacking mechanism connected with the ejecting plate. The unpacking mechanism comprises a first driving device installed on the ejecting plate, a first installation plate which is arranged below the ejecting plate and connected to the driving end of the first driving device, and a plurality of unpacking rods which are assembled on the first installation plate and extend towards the lower portion of the first installation plate in parallel, the unpacking rods have the perpendicular movement degree of freedom and multiple pieces of third perpendicular projection projected on the horizontal plane, and the multiple pieces of third perpendicular projection is distributed around the first perpendicular projection and overlapped with part of the second perpendicular projection. Due to the fact that the unpacking mechanism is arranged, the unpacking machine and a robot are in linkage, the robot automatically carries the sand package to the unpacking machine to carry out unpacking, finally the casting in the sand mold is automatically taken out, and the automatic production of sand package unpacking is achieved.

Description

technical field [0001] The invention relates to the field of casting molding, in particular to a sand mold crushing device in the field of casting molding. Background technique [0002] In foundry production, the original sand, binder and other auxiliary materials are used to form under the action of external force and reach a certain degree of compactness or density. The resulting casting cavity is called a sand mold. Sand casting is a method of producing castings in sand molds. Casting method, after the casting is poured, the sand mold wrapped on the outside of the casting must be removed, and then the casting product is taken out. [0003] In the current production, the sand mold is generally broken manually to take out the poured castings. On the one hand, manual breaking is prone to uneven force, and it is easy to break the castings in the sand mold, resulting in a high scrap rate. On the one hand, manpower smashing consumes a large amount of manpower, and the producti...
