| Abstract: | According to the structural characteristics and technical requirements of automotive rear-lamp housing, a large hot runner and precision injection mould was designed. The problem of the plastic part leave in the cavity side was solved by increasing the draft of cavity and inverted thread and reinforcing rib at the core side. The trouble between the rod and side slider was eliminated by adopting the pre-reset mechanism. By improving the temperature control system, the injection cycle was shortened by 8%. The dimensional accuracy of the moulded parts meets the design requirements of MT3, and has passed various tests which proves the mechanism of the mould is advanced and reasonable. |
