Abstract: Method whereby coinjection molding shooting pot actuation structure is configured to be installed in a coinjection hot runner with a coinjection nozzle, the coinjection nozzle having at least two melt channels ending at the same gate. The shooting pot is preferably disposed in one of a mold cavity half and a mold core half. A shooting pot piston is configured to discharge a melt from the shooting pot. A transmission structure is configured to (i) extend through one of the mold cavity half and the mold core half, and (ii) to transmit a force to the shooting pot piston. Actuation structure is disposed on the opposite side of the mold cavity half from the coinjection hot runner, and is configured to provide the force to the transmission structure.

Abstract: An actuator for a hot runner has a piston and a valve pin holder threadably connected to the piston. The piston can be translated by fluid pressure and rotated by an electric motor. The valve pin holder is rotationally fixed, and therefore moves along the thread when the piston is rotated. A valve pin connected to the valve pin holder moves in response to fluid pressure and also in response to the electric motor rotating the piston.

Abstract: An injection mold assembly for formation of thin walled multi-partitioned plastic containers. An array of cantileveredly mounted and spaced apart cores are extendable into a female mold assembly which includes a pair of side cavity cams and end cavity cams closeable upon the array, but spaced therefrom to form the plastic container therebetween. A plurality of side locking wedge shaped fingers are extendable into the slots spacing the cores apart. The fingers are arranged to extend into the opposite sides of the array of cores in a direction perpendicular to the longitudinal axis of the array spacing the cores apart while plastic is injected into the assembly by injectors mounted to the female mold. A pair of end pushers contact the two outermost cores in the array limiting outward movement of the cores during the injection step. The end pushers likewise extend in a direction perpendicular to the longitudinal axis of the array. In two embodiments, the fingers are moveable to and from the array by vertical or horizontal hydraulic cylinders and are moveable apart from the side cavity cams as the mold assembly is opened. Further side locking members move externally against the cores limiting outward movement thereof.
