数值模拟与实验研究锁模距离对内循环两板注塑机形变的影响

iming at the problem of large deformation deviation of the existing four-cylinder clamping internal circulation injection molding machine, this paper carried out the deformation test experiment and numerical simulation analysis of the key clamping components of the injection molding machine, focusing on the influence of the length of the mold, the clamping distance on the deformation of the clamping system. We also analyzed of the differences between the experimental data and the simulation data and the influencing factors of these differences. The research results showed that the numerical simulation data was biased in some cases due to the experimental error. However, some data and the overall trend were accurate and effective. The higher mold length (clamping distance) increased the deformation of the clamping system. However, it had little effect on the deformation of the rear end of the clamping cylinder.
