Optimization method for sealing mode of filling port of liquid composite node

A method for optimizing a liquid composite node filling port sealing mode comprises the steps that a steel ball is driven into an independent flow channel to simulate sealing of a liquid composite node filling port, a filling pump is connected to one end of the flow channel to inject high-pressure liquid into the flow channel, and whether liquid leaks out of the other end of the flow channel or not is checked; and the steel balls with proper hardness and size are selected to be matched with the runner. According to the invention, the filling pump is connected to the sealing structure of the simulated filling port for high-pressure filling of liquid, and the stress of the sealing structure is simulated, so that whether the hardness and size of the selected steel ball are appropriate is judged, and the best effect is achieved at the lowest cost. 一种液体复合节点灌注口密封方式的优化方法，在独立的流道内打入钢珠模拟液体复合节点灌注口的密封，在流道的一端处连接灌注泵往流道内注入高压液体，检查流道另一端是否有液体漏出，进而选择出合适硬度和大小的钢珠与流道匹配。本发明通过采用在模拟的灌注口密封结构处连接灌注泵高压灌注液体，模拟密封结构的受力，进而判断所选取的钢珠的硬度和大小是否合适，
