Waste sand collecting device for full-automatic sand shooting machine

Abstract

The invention discloses a waste sand collecting device for a full-automatic sand shooting machine. The waste sand collecting device comprises a waste collecting assembly and a sand shooting machine body, a sand shooting mechanism is fixedly mounted at the upper end of a supporting column, a mounting frame is fixedly mounted at the upper end of the supporting column, and after the sand shooting mechanism completes work, waste can directly fall into the waste collecting assembly; a magnetic block is fixedly installed at the upper end of the inner wall of a first cavity and can adsorb iron substances in the waste, a filter screen is fixedly installed in the first cavity, fine substances such as dust are attached to the surface of the filter screen, waste sand can directly fall down, and a draught fan is started through a control panel, so that air is sucked into a filter mechanism from an air suction opening, and the dust in the first cavity is conveniently sucked away; and the filter screen is fixedly installed at the upper end of a fixing ring, through holes are formed in the upper surface of the fixing ring, the dust can be adsorbed to the upper surface of the filter screen throughblocking of the filter screen, the waste sand falls off from the through holes, the sucked waste sand can return to a collecting box through a sand outlet pipe to be stored, and the filtering effectis good.

Description

technical field [0001] The invention relates to the technical field of sand shooting machines, in particular to a waste sand collection device for a fully automatic sand shooting machine. Background technique [0002] The working principle of the core shooting machine is to inject the coated sand into the heated metal core box mold with compressed air, and the coated sand will solidify quickly when heated in the core box mold. After reaching a certain strength and thickness, open the mold and take it out. , to form a high-quality sand core with smooth surface and precise size to facilitate pouring of molten iron after assembly. The core or shell manufactured by the core shooter has high precision in size, good surface quality, and high finish of the finished product. [0003] Existing sand shooting machines need demoulding treatment after the sand core is cast, and a certain amount of waste sand will be generated in the demolded mold, which can be reused after collection, bu...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a waste sand collection device for a fully automatic sand shooting machine, which has the advantages of being convenient for waste sand collection and having a good filtering effect, thereby solving the problem of the generation of certain waste sand in the demoulding mold in the background technology. However, the existing waste sand collection is more troublesome, and some dust and other substances will be generated during the air contact process, which is inconvenient to filter and stay in the mold to affect the next sand core casting, and the use effect is not good.
