木模浇道制作工艺改进

Improvement of Production Process for Wooden Pattern Runner

浇道是木模不可缺少的组件之一,传统浇道制作的连接方式多采用手工扒槽镶嵌结构,制作比较费时。现采用等分角度对接结构,制作比较方便、省时,对于单件铸件的模型制作,选用泡沫型材进行等分角度对接结构制作浇道,更是方便。

The runner is an indispensable component of wooden pattern, of which connection mode is a time-consuming inlay structure connected by the manually-chiseled groove in the traditional process. Now the angle bisector butt joint structure is adopted, which is easier and timesaving than the traditional one. For the manufacture of a single casting pattern made from foam profiles, the production of runner through the angle bisector butt joint structure is more convenient.
