Abstract
ABSTRACT Determining the parameters of the sand moulding process plays an important role in obtaining green sand mould without wasting the energy used in the moulding process. The present work focuses on studying the variation effect of the sand density and elasto-plastic properties on the compaction process of sand moulding. Triaxial and uniaxial compression tests were used to estimate the properties of bentonite-bonded green sand. The behaviour of the green sand mould during the compaction process was investigated numerically by commercial finite element software, and experimentally using a flowability sensor. Detection of the green sand movement by a flowability sensor showed good agreement between the experimental and numerical results. Similar behaviour was observed for the distance-dependent displacement decrease with increasing green sand density. Stress concentration has an effect on the sand flow, density distribution and displacement of green mould sand.
