Abstract

Aiming at exploiting the impact of filling rate and pressure difference on thin-wall product during filling stage of differential pressure vacuum casting (DPVC) process and based on Yeoh model, a finite element mathematical structure model of silicon rubber is proposed. Employing nonlinear Finite Element Method (FEM), the impact of soft moulds deformation on products dimensional precision during different pressure difference is studied. Finally, the experiment carried out on a sample machine verifies that the solution of established finite element mathematical structure model of silicon rubber is very close to experiment result and thus provides an effective method for optimizing the pressure difference and mould optimized design.
