Abstract: In this paper, the clamping unit of a two-platen injection molding machine was modeled by Pro/ENGINEER, and was imported to Altair HyperWorks. In HyperMesh module, the finite element model was set up, ANSYS has been used in the finite element analysis of the clamping unit and the deformation and stress results were obtained. Based on the topology optimization of HyperWorks/OptiStruct, recommendations to improve the structure of the clamping mechanism are presented; the results showed that less material was used while its performance was maintained.

Abstract: The performance advantages of the newly full-hydraulic internal circulation two-platen injection molding machine were investigated deeply and comprehensively. The application prospects were also forecasted. Thanks to the use of internal circulation cylinders in the injection molding machine, the hydraulic system is greatly simplified. Mold-moving and mold-locking are actuated by different cylinders respectively which not only balance the force and velocity but obtain excellent mold-locking properties and high molding stability. The injection molding machine was equipped with servomotor which drives quantified pump in order to save energy and lower noise. The newly full-hydraulic internal circulation two-platen injection molding machine will be the next generation injection molding machine.
