连接环注射模结构可行性分析与设计

The Feasibility Analysis and Design of Injection Mold Structure for the Connecting Ring

通过对连接环形体分析，找到了其外形上有弓形高和3处凸台与内形中有2处凸台“障碍体”。由于连接环产量较少，只能采用低效的模具结构方案。经过充分论证分析，连接环以放在模具中倒置位置方案为最佳优化方案。成型连接环外形，采用了弯销和滑块抽芯机构。成型连接环内形的型芯，是以R2-0/0.2mm凸台A面为分型面，将A面内凸台分成五个独立部分。抽取中间部分可腾出足够空间，再分别抽取其它四部分，避开内形2处凸台对连接环脱模的阻挡，以到达脱模的目的。该模具结构方案，能使连接环顺利地成型和脱模。但手工抽取5块模块毕竟效率低下，故只能适应小批量产品的加工。若要实现大批量加工，得将手工抽取5块模块改成自动化抽芯才行。

According to the analysis of the ring body, it is found that there are two convex sets and three convex sets in shape ＂. Due to the low yield of the connecting ring, the low efficiency of the mold structure can only be used. Through the full proof analysis, the connecting ring is put in the mold upside down position scheme as the best optimization scheme. The shape of the connecting ring is formed, and the bent pin and the sliding block core pulling mechanism are adopted. Molding connection type core ring profile, with R2 _0/0.2 mm convex A surface as the parting surface, the A plane boss divided into five separate parts. The middle part can be extracted to make enough space, and then take the other four parts, to avoid the blocking of the inner shape of the two convex sets to the connecting ring, so as to reach the goal of the stripping. The structure of the mold can make the connecting ring to be smoothly formed and mold release. But the manual extraction of five modules, after all, the efficiency is low, it can only adapt to the small batch of products processing. If you want to achieve a large batch processing, you have to manually extract the five modules into automated core pulling.
