摘要低压注塑是一种新型的注塑技术，但是国内低压注塑技术的发展尚处于初始阶段。因此，通过改进低压注塑设备（包括胶缸、胶管等）发展我国的低压注塑技术是意义重大的。
本论文研究的主要内容包括深入分析低压注塑原理以及设备的系统组成，并对其中的关键部件进行设计与分析，包括胶缸、安全阀、齿轮泵、胶枪、胶管以及合模机构的设计与分析。针对现有机械设备的不足，运用SOLIDWORKS软件建立改进的模型，再通过ANSYS软件分别对原有设备和本次设计的组件进行实验分析，具体包括对胶缸进行瞬态热分析，对齿轮泵的齿轮轴以及安全阀的顶杆进行强度校核，通过比较分析结果来评价设计方案的可行性。本论文提出的改善方案对于现有的低压注塑设备具有一定的参考价值。30050

Title The mechanical structural design of low pressure injection molding equipment
Abstract
Low pressure injection molding is a new type of injection molding technology, but the development of the domestic low pressure injection molding technology is still in its initial stage. Therefore, improving the low pressure injection molding equipment including the rubber cylinder and hose to develop the low pressure injection molding technology is significant in our country.
The main contents of this paper studies include the thorough analysis of low pressure injection molding principle and system components of equipment, and the design and analysis of key components, including plastic cylinder, valve, pump, glue guns, rubber hose, and the design of clamping mechanism and analysis. Aiming at the shortcomings of the existing machinery and equipment, the improved model is established using SOLIDWORKS software, and then through the ANSYS software, the original equipment experimental analysis and the design of components, including transient thermal analysis was carried out on the rubber cylinder, gear shaft of the gear pump and valve plunger intensity, and comparing the analysis results to evaluate the feasibility of the design. The improvement plan of this paper has a certain reference value for existing low pressure injection molding equipment.
Keywords Low pressure injection molding Plastic cylinder heat transfer
