Molding sand quality is one of the important factors affecting the quality of castings.Portable detection device for molding sand properties,especially multi-parameter portable detection device,plays an important role in mold quality control.In this paper,a portable detection device based on single chip microcomputer testing and controlling was developed,which can finish the detection of compaction rate,water content,air permeability and wet compressive strength of wet clay sand synchronously in site.The testing principle,hardware composition,software design and measured results of the detection device were introduced in this paper.The relative error between the portable detection device and the standard method was that the compaction rate was 0.60%,the water content was 2.12%,the air permeability was 1.87%,the wet compression strength was 1.61%,and the detection time was less than 2 min,which proves that the portable detection device has high test accuracy and working stability.
