笔记本电脑屏幕框热流道注射模具设计

通过对笔记本电脑屏幕框的结构及成型工艺分析，对该塑件的热流道注射模具进行了设计。重点围绕模具的分型面、浇注系统、侧抽芯机构、推出机构、排气及冷却系统等方面展开了设计分析，确定了模具合理的组成结构。通过对模具的热流道浇注系统、滑块侧向抽芯对分型面的调整及斜推杆内侧抽芯的改良性设计，进一步提高了塑件质量与生产效率，降低了制造成本，为同类结构特点的注射模设计提供了参考。

Design of Injection Mould with Hot Runner for Notebook Computer Display Frame

A hot runner injection mould for notebook computer display frame was designed based on the process and structure of the frame. The analysis of parting surface, the gating system, the side core pulling mechanism, exhaust and the cooling system of the mould was carried out and a reasonable mould structure was determined. The sophisticated design of the hot runner, the slider and the slanted ejector pin not only increased the quality of the product and labor capacity, but also reduced the machining cost of the product. An idea for the injection mould design of similar parts was given.
