In one embodiment, a vertical mold clamping apparatus includes a fixed platen, a turntable placed on the fixed platen, and a plate which is provided between the fixed platen and the turntable and supports the turntable so as to be rotatable, and a lubricant is supplied from a lateral side of the plate to an upper surface of the plate that faces a lower surface of the turntable.

An injection molding apparatus for producing a plastics molding comprising a first component, a second component, and a third component comprises a first mold plate having at least 3 first mold nests, and a second mold plate having at least 3 second mold nests. In the closed state, the mold plates cooperate in the production of the plastics mold. In the opened state, the second mold plate is rotatable relative to the first mold plate. The at least 3 second mold nests comprise, in a case A), at least two second mold nests for injection molding the first component, and at least one second mold nest for injection molding the third component, or, in a case B), at least two second mold nests for injection molding the second component, and at least one second mold nest for injection molding the first component.

A rotary multi-injection molding machine includes a rotary station in which a rotational driving source is disposed; a rotary disposed above the rotary station and rotates by the rotational driving source; a plurality of molds disposed spaced apart from each other on the rotary, in which a cavity is formed at least one of a fixed mold and a movable mold, and in which an injection passage through which material passes is formed in the movable mold; an injection molding machine for molding and supplying a material; a guide having a guide passage formed therein for guiding the material supplied from the injection molding machine to the injection passage; a lifting and lowering mechanism for lifting and lowering the guide; in which the guide, when the guide is lowered by the lifting and lowering mechanism, may press the movable mold from above the movable mold.
