The Research on Injection Mould Design of Bearing Cylinder Plastics

摘要

It is analyzed by the technology plastics materials and molding process of bearing cylinder pieces, which has carried on the mold scheme demonstration and demoulding mechanism, the forming problem of bearing cylinder pieces is solved, and it is designed that the main runner, cold slug well, pull rod, the runner and gate of gating system. The ejection force is calculated, and which is design of parting surface. It is given to the assembly diagram of special injection mould. Practice has proved that the bearing cylinder pieces injection mold structure is reasonable, reliable, good machining quality and high production efficiency.
