Abstract:

The camera support component presents significant molding challenges due to its complex structure， high precision requirements， and stringent surface quality standards. To achieve optimal molding quality， the mold design incorporates several innovative features： （1） a submarine gate positioned in the moving half， enabling melt to flow through product additives via plastic sheeting； （2） a sophisticated core⁃pulling system with four side mechanisms， including two angled core⁃pullers in the moving half； and （3） an innovative adaptation of three⁃plate mold parting principles， where an angled pulling split fixed to the support plate serves as a transmission element. During operation， mold opening force between the support plate and moving half plate drives angled sliders along T⁃slots in the pulling split， achieving precise angled core⁃pulling through guided movement along the main core's angled holes. Trial results confirm the mold structure's reliability and effectiveness， producing components that meet all quality specifications.
