内循环二板直压式注塑机液压合模系统的实验与模拟

In order to characterize the properties of the clamping system of an internal circulation injection molding machine, experiments were conducted on an injection molding machine under different processing conditions. The variation of the plate displacement and cylinder pressure were measured. AMESim software was used to establish a hydraulic model of the internal circulation mold clamping system, and numerical simulation was conducted to calculate the related parameters. Through the analysis of the plate displacement and cylinder pressure by experiment and simulation, it verified the reliability of simulation by AMESim. The experiment and simulation results at different processing conditions showed that increasing clamping speed could shortenExperiment and Simulation for the Hydraulic Clamping System of an Internal Circulation Two-platen Injection Molding Machine cycle time but excessive closing speed would have a great damage to the mold.
