Abstract:
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.
