| 摘要 |
The present invention relates to a hot runner valve apparatus for an injection-molding machine, which has, instead of a complicated mechanical opening/closing structure, a simple structure that enables an elevating pin, through the interior of which a resin flows, to be elevated, to easily control a supply of the resin injected into a cavity of a mold, so that the molding condition for a small precise part component, or in the event a resin having poor flowability is used, is improved, thereby increasing mass-production capabilities and reducing defects in molded articles.
