出风网注射模具设计及制造

Manufacture and design of the injection mould for the wind-net

本文以柜式空调器出风网为例详细阐述了三板式点浇口注射模具的结构设计要点与工作过程，通过采用典型的多滑块抽芯结构、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；经过在实战中不断优化选材和热处理工艺、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 counter air-condition wind-net as an example,the main desing poinr and working praces of the pin-point gate mould of three plates are stated in detail. The service life and realiability of the mould is greatly improved by the cypical sliding-block scructures 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 select material and heat treatment 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.
