20130302466 | COOLING DEVICE FOR THE DRIVE FOR ADJUSTING THE NEEDLE OF A NEEDLE VALVE NOZZLE IN HOT RUNNER SYSTEMS FOR INJECTION MOLDING MACHINES - Cooling device for the drive for the adjustment of the needle ( | 11-14-2013 |
20120181728 | INJECTION MOLDING NOZZLE - An injection molding nozzle for dispensing of molten material includes an elongated body member having an outer surface, a first portion at a proximal end, a second portion at a distal end, and a central passageway extending longitudinally therethrough from the first portion to the second portion. The central passageway includes an inlet defined at the proximal end and splits outwardly at the second portion to form a radially extending passageway leading to an outlet. A tip member is coupled to the outlet to facilitate dispensing of molten material into a mold cavity. A groove is defined on the outer surface of the body member that winds from the first portion to a heated section of the second portion that is positioned adjacent to the tip member. | 07-19-2012 |
20100225025 | PROCESS AND DEVICE FOR CASCADE INJECTION MOLDING - A cascade injection molding system includes a plurality of nozzles each having a valve rod driven by a piston cylinder drive, for injecting melt into the mold cavity. A throttle check valve is located within a pressurizing medium line to regulate nozzle operation. The method includes injecting the melt at feed orifice using a needle valve-controlled needle valve nozzle associated with each feed orifice into the cavity of the molding tool. The needle valve nozzles is opened at different times by controlling the opening speed and the injection pressure at the feed orifices, via the corresponding piston-cylinder drives for the needle valve nozzles. The pressurizing medium discharge from the piston cylinder is throttled for at least one of the piston-cylinder drives when the nozzle is opened. | 09-09-2010 |
