Stringing prevention block and the injection molding machine of the nozzle apparatus having the same

摘要

(57) [summary] in (modified with) OBJECTIVE molding operation process, null meter goods molten material at the time the leaves off the junction of the sprue and the nozzle land when removed from the mold to the thin thread by Nobeshin it becomes, it becomes stringy phenomenon, to prevent this completely. [Configuration] molding machine injection nozzle (an injection mouthpiece) baffle plate integral 3 provided in the apparatus of the nozzle tip, or replacement-type, and are formed at the nozzle tip 2 having a honeycomb pins. [Effect] the molten resin by the baffle plate is the minute flow at the contact portion of the nozzle tip land portion and the mold sprue (touch surface), the nozzle in the land becomes a separate state is a semi-solidified state, and cold in the nozzle land portion to the sprue side stringing phenomenon does not occur at the time away cut in full is Ika brought the slag
