套管接头注塑模具设计

Design of Injection Mold for Casing Joint

对塑料管道套合用接头(套管接头)的结构进行了塑件分析,并设计了注塑模具。详细介绍了套管接头注塑模具型腔的组成与分型面的选择,以及该模具浇注系统结构、螺纹型芯结构及自动脱螺纹机构的设计。实践结果表明:该模具设计方案合理、结构简单紧凑、动作可靠,且无运动方向改变问题。

On the basis of analysis of plastic casing joint structure,the injection mold of the plastic part was designed.In this paper,the selection and constitution of casing joint injection model cavities and parting surface,the structure design of injection system,and threaded core structure and its automatic thread demoulding structure,were introduced in detail.The practical result shows that the model is reasonable in design,simple and compact in structure,reliable in motion and shows no changing problem in motion direction.
