| 为了降低注塑模浇口套工作时的使用温度，减小其形变以提高使用寿命，课题组以风扇叶片注塑模为例研究注塑过程中高温、高压熔融塑料对浇口套结构的影响。利用有限元软件ANSYS在注塑模型腔最大压力下对注塑模浇口套进行结构研究，在此基础上根据热弹性耦合理论对其进行热力耦合分析，发现在型腔压力一定时注塑模温度增高会导致浇口套形变增加，影响浇口套的使用寿命；故提出一种浇口套冷却系统，并利用ANSYS CFX进行传热流动分析。研究结果表明：冷却系统能明显降低浇口套工作时的使用温度。研究达到了减小注塑模浇口套形变、提高其使用寿命的目的。 |

| For injection mold sprue sleeve, in order to reduce the operating temperature during operation, reduce the deformation to improve the service life. Taking the fan blade injection mold as an example, the influence of high temperature and high pressure molten plastic on the structure of the sprue sleeve during the injection process was studied. The structural analysis of the maximum pressure of the injection molding cavity was carried out by means of the finite element software ANSYS. Based on thermo elasticity coupled analysis, the thermo mechanical coupling analysis was carried out. It was found that the temperature of the injection mold increased when the cavity pressure was constant, which would lead to an increase in the shape of the sprue, affecting the service life of thesprue sleeve; therefore, a sprue sleeve cooling system is proposed, and the heat transfer flow analysis is performed by ANSYS CFX. The results show that the cooling system can obviously reduce the operating temperature of the sprue sleeve , which aims to reduce the deformation and improve the service life. |
