拉杆注射模具设计及制造

Design and manufacture of the Injection Mould for the pull-staff

本文以拉杆为例详细阐述了两板式潜伏浇口注射模具的结构设计要点与工作过程，通过采用典型的型芯结构，多弹簧顶出复位系统，使得模具的使用寿命和可靠性大大提高；经过在实践中不断优化加工工艺、控制加工精度和改进配模技术。从而大大缩短了配模时间和模具的制造周期，提高了劳动生产效率，降低了模具的制造成本。

With the pull-staff as an example, the main design point and working process of the fallow gate mould of two plates are stated in detail. The service life and realiability of the mould is greatly improved by the typical core structure and ejector-return system Of many springs . The time of mould-make up and the cycle of mould making are greatly shortened by the optimize of machining technics ,the control of machining accuracy and the improvement of mould-make up technique in practice.At the same time,the labour productivity is improved and the manufacture cost of the mould is geatly depressed.
