| 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/shutting structure, a simple structure that enables an elevating pin, through the interior of which a resin flows, to elevate, thus easily controlling the supply of the resin being injected into the cavity of a mold, the result being that the molding condition for a small precise part component, or in the event a resin having poor flowability is used, is improved to increase mass-production capabilities and reduce defects in molded articles. |
