    摘要： Disclosed, amongst other things, is a molding apparatus and an injection molding process. The molding apparatus includes a positioner that is configured to regulate, in use, a relative position between a gate member and a nozzle of a melt distribution apparatus between a retracted position and an extended position for adjusting a volume of a nozzle melt reservoir that is definable between the gate member and the nozzle between a reduced volume and an expanded volume, respectively. The injection molding process includes regulating a relative position between a gate member and a nozzle of a melt distribution apparatus, with a positioner, into one of a retracted position and an extended position for adjusting a volume of a nozzle melt reservoir that is definable between the gate member and the nozzle between a reduced volume and an expanded volume, respectively.

    摘要： A nozzle body defines an upstream channel. A downstream bracing portion has a lateral bore. A nozzle tip extends laterally through the lateral bore of the bracing portion and has a sealing surface for engaging a gate component that defines a mold gate. The runnerless nozzle further includes a securing component inserted into the bracing portion to hold the nozzle tip against the bracing portion. The bracing portion or the securing component defines a lateral channel in communication with the upstream channel for delivering molding material to the nozzle tip. The nozzle tip can be removed by removing the securing component.

    摘要： A valve pin adjustment system is provided for use in valve gated injection molding applications which enables adjustments to the positioning of the valve pin without necessitating removal of the clamping plates (12) and valve assembly components, including valve pins (19). A piston (22) associated with the valve pin includes a cylindrical body having first and second co-axially aligned internally threaded bores (22b, 22c) of respective first and second diameters. Preferably, the threads formed in the first and second bores are of the opposite hand. First and second externally-threaded cylindrical valve pin positioning members (28, 29) are respectively received in the first and second bores. Each of the positioning members includes a head portion and a tip portion. The tip of the second positioning member is in contact with the head of the first positioning member to lock the first positioning member in place and the tip of the first positioning member is in contact with a head portion on the valve pin to locate the valve pin.
