ABSTRACT:
The invention provides a vertical injection molding machine capable of stopping the repeatedly revolved turntable at predetermined positions. During operation of a vertical injection molding machine1having one or more lower molds15mounted on a turntable14and an upper mold16mounted on an upper retention plate13, lubricant is periodically fed from a pump30to a slide portion S of the revolving turntable14. Thereby, the slide resistance of the sliding portions S of the turntable14is maintained constant, by which the repeatedly revolved turntable14is enabled to stop accurately at predetermined positions. Thus, the present machine enables the lower molds15which are repeatedly clamped with the upper mold16to stop at predetermined positions.
