Problems solved by technology

[0002] One of the main reasons for large castings to produce unqualified products is inclusion defects, which will cause a lot of quality, cost and efficiency problems in casting production
[0003] The sprue cup is a very important part in the gating system, but in the prior art, the sprue cup cannot remove a large amount of liquid metal during the pouring process. Slag and other inclusions make the occurrence probability of slag inclusion and inclusion defects higher, and the pass rate of castings is lower

Abstract

The invention relates to a filtering type pouring cup and a sand box, and relates to the technical field of pouring cups. The filtering type pouring cup comprises a cup body and a filter plate, the cup body is provided with an inner hole, the filter plate is arranged on the inner surface of the inner hole in the axis direction of the inner hole and divides the inner hole into a first cavity and a second cavity, the first cavity is provided with a liquid inlet, the second cavity is provided with a liquid outlet, the liquid inlet and the liquid outlet are formed in the two ends of the cup body respectively, and a plurality of filter holes are formed in one end, away from the liquid inlet, of the filter plate. According to the filtering type pouring cup and the sand box, the filter plate is additionally arranged in the cup body, slag in liquid metal can be filtered by utilizing the filter holes in the filter plate, so that the probability of occurrence of slag inclusion and inclusion defects is reduced, and the qualification rate of castings is increased; and the flow inlet speed of liquid metal can be buffered, the flow speed can be adjusted, turbulent flow can be reduced, sand washing can be avoided, primary slag can be effectively reduced, the secondary slag inclusion defect can be relieved, and an obvious effect on solving the slag inclusion defects of the castings can be achieved.

Description

technical field [0001] The present application relates to the technical field of sprue cups, in particular, to a filter type sprue cup and a sand box. Background technique [0002] One of the main reasons for large castings to produce unqualified products is inclusion defects, which will cause a lot of quality, cost and efficiency problems in casting production. [0003] The sprue cup is a very important part in the gating system, but in the prior art, the sprue cup cannot remove a large amount of slag and other inclusions in the liquid metal during the pouring process, making the probability of occurrence of slag inclusions and inclusion defects relatively low. High, the pass rate of castings is low. Contents of the invention [0004] The purpose of this application is to provide a filter sprue cup and sand box, which can use the filter holes on the filter plate to filter slag and other inclusions in liquid metal, so as to reduce the occurrence probability of slag inclus...
