direct gate

According to the structure characteristics of connecting part with complex profile, through proper selection of a direct gate and a simple parting line and reasonable combination of the slant ejection pin, slant dog_leg cam and spring of the core_pulling system, the mould structure was designed simple and the mould works flexibly, stably and safely.

根据复杂外轮廓连接件的结构特点 ,合理选用直浇口和简单分型面 ,通过斜推杆、斜弯销、弹簧等抽芯机构的有机组合 ,使模具结构简单 ,运行灵活、平稳、可靠。

The design and the calculation methods of the parameter of the routine main sprue and the style and the dimension selections of the leaning main sprue are discussed.

论述了塑料注塑模直浇口式主流道参数的设计与计算方法,倾斜式主流道的形式、尺寸选取,最后举例说明了倾斜式主流道的应用。
