Sand material detection structure

Abstract

The invention discloses a sand material detection structure. The structure comprises a sand hopper, wherein a material level detection mechanism is arranged in the sand hopper, and comprises a plurality of contact probes which are arranged on the inner wall of the sand hopper from top to bottom sequentially and are connected with a controller. By adopting the sand material detection structure, real-time automatic detection on the number of molding sands in the sand hopper can be implemented, thereby effectively avoiding the phenomenon that clay core waste is produced due to the reduced number of the molding sands in the sand hopper, and effectively improving the yield of clay core produced by a box core shooter.

Description

technical field [0001] The invention relates to the field of foundry, in particular to a sand material detection structure capable of detecting the height of molding sand in a sand hopper. Background technique [0002] In the modern casting production process, in order to improve the efficiency of casting and meet the requirements of modern production, most of the cores used in the casting process are manufactured by the hot core box core shooter. The core shooter is widely used in the foundry machinery industry. The core produced by the hot core box core shooter has the advantages of accurate size and smooth surface, so it is widely used in many foundry enterprises. [0003] In the process of producing mud core by the hot core box core shooter, it is necessary to monitor the amount of molding sand in the sand hopper in real time to prevent the amount of molding sand in the sand hopper from becoming less and unable to supply sand in time, thereby affecting the normal operati...

AI Technical Summary

Problems solved by technology

[0003] In the process of producing clay cores by the hot box core shooter, it is necessary to monitor the amount of molding sand in the sand hopper in real time to prevent the amount of molding sand in the sand hopper from decreasing and the sand cannot be supplied in time, which will affect the normal operation of the core shooter. There is a phenomenon that the mud core is scrapped due to insufficient sand supply

At present, the detection of the amount of molding sand in the sand bucket is usually only observed by human eyes, but the method of human eye observation cannot wake up and observe the amount of sand in the sand bucket in real time, so sometimes there is still insufficient sand in the sand bucket However, the problem affecting the sand supply makes the waste rate of the mud core higher
