doi:10.19491/j.issn.1001-9278.2010.03.022

Abstract

Abstract: Based on an analysis of the structure and process characteristics of spur-helical gear, the structure and working process of the injection mold with helical-gear demolding were introduced. In the present mold design, the helical-gear demolding was realize through a gear-cavity rotary mechanism, slide-pull was achieved by bevel guiding-post and half mold, and four-plate mold structure was used to finish three separating according to distance.

Key words: spur-helical gear, injection, gear-cavity rotary mechanism, separating according to distance
