YANG Si-han;HAO Bo;School of Mechanical Engineering,Shenyang Ligong University;
Based on the process analysis on a thin-wall models sharpener, an injection mould was presented. The cavity, parting line and feeding system were determined, and the circular ejector pin was used to push the plastic, and the fitting clearance was used to exhaust gas. Practice proved that the mould structure was reasonable, and each system was matched well, the plastic parts could meet the use requirements.
