20090057593 | Staggered Cylinders in a Valve Gate Apparatus - A valve gate piston assembly, in an injection molding system, is positioned in a staggered arrangement such that one piston assembly overlaps that of another valve gate piston assembly thereby minimizing an overall centerline pitch between said piston assemblies. Such a superposed layout of piston assemblies enables larger diameter pistons to occupy a smaller footprint than would be realized should the same piston assemblies be positioned side by side. The use of relatively larger diameter pistons results in an increased force available, for the same input air pressure, to actuate the pistons and valve stems attached thereto, resulting in a higher valve stem closing force. A staggered piston assembly layout also allows independent air circuits to control each piston separately. A combination of multiple piston assemblies may be configured in such a staggered, overlapping array. | 03-05-2009 |

20090191300 | Flexible Plate Slot for a Hot Runner Injection Molding System - A flexible plate system for a hot runner assembly includes a backing plate; a manifold plate detachably connected to the backing plate; a manifold positioned between the backing plate and the manifold plate and having at least one nozzle associated therewith; and wherein the manifold plate has at least one plate slot that allows the nozzle to extend through the manifold plate and having at least a first lateral dimension substantially larger than the outside diameter of the nozzle. The manifold plate and the backing plate may be configured to have at least one manifold plate cavity and at least one backing plate cavity to accept at least one nozzle insert and at least one piston cylinder insert respectively, the nozzle insert having a nozzle bore or a plurality of insert slots therethrough for installation of the nozzle, and the piston cylinder insert having a cylinder bore for a piston cylinder. | 07-30-2009 |
20090191302 | Reconfigurable Hot Runner - A hot runner system having a melt distribution system that is reusable and reconfigurable to vary drop or nozzle locations to meet various design requirements. The melt distribution system includes a melt distributor in fluid communication with a melt source, at least one melt conduit in fluid communication with the melt distributor, and at least one nozzle in fluid communication with the at least one melt conduit. The hot runner system also includes a backing plate; a manifold plate detachably connected to the backing plate; a melt distribution system positioned between the backing plate and the manifold plate and having at least one nozzle associated therewith. The hot runner system may be configured and reconfigured to accommodate various drop or nozzle locations. | 07-30-2009 |
20090236774 | Melt Distribution Apparatus for Use in a Hot Runner and a Related Method for a Balancing of Melt Flow - Disclosed, amongst other things, is a melt distribution apparatus of a hot runner and a related method for balancing melt flow to a plurality of drops. The melt distribution apparatus includes a plurality of chokes with each choke of the plurality of chokes being associated with a corresponding one of a drop of a plurality of drops. Each choke of the plurality of chokes being configured to contribute, during an injection of a molding material therethrough, a choke melt-pressure loss such that the plurality of chokes contribute an aggregate choke melt-pressure loss that is generally between 10% and 75% of an aggregate hot runner melt-pressure loss. | 09-24-2009 |
20090274790 | SHOOTING POT FOR FEEDING MULTIPLE NOZZLES - A hot runner system including a shoot pot system for transferring melt from a single shooting pot to multiple nozzles. Melt is fed from a source of melt into the cavity through the multiple nozzles, and a valve isolates melt in the cavity from melt in the source. A plunger within the cavity is driven forward to inject melt in the cavity into a mold cavity at high pressure without significantly increasing the pressure of melt in the source. The plunger optionally functions as both the plunger and the valve by opening and closing communication between the cavity and the manifold as it is rotated. | 11-05-2009 |
