Patent attributes
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 machine 1 having one or more lower molds 15 mounted on a turntable 14 and an upper mold 16 mounted on an upper retention plate 13, lubricant is periodically fed from a pump 30 to a slide portion S of the revolving turntable 14. Thereby, the slide resistance of the sliding portions S of the turntable 14 is maintained constant, by which the repeatedly revolved turntable 14 is enabled to stop accurately at predetermined positions. Thus, the present machine enables the lower molds 15 which are repeatedly clamped with the upper mold 16 to stop at predetermined positions.
