A valve gate manifold for an injecting machine has at least three plates in tandem with one another, the first plate being circular and having in its several die positioning rings each with an injecting nozzle, the second plate being a manifold plate having a master valve and internal passages leading to the injecting nozzles, and the third plate carrying piston/cylinder assemblies which control the injecting nozzles. The face of the first plate can lie copolanar with the platen face of the injecting machine, and the manifold can be contained in an aperture through the platen.
