Title:
INJECTION SYSTEM HAVING ADIABATIC MEANS
Document Type and Number:
WIPO Patent Application WO/2010/123329
Kind Code:
A2
Abstract:
The present invention relates to a system for injection molding, more particularly to an injection system capable of reducing the loss of resin and improving the molding quality, by providing adiabatic means to joint regions between a molten resin distribution means and an external mold and between a nozzle and a mold, respectively, such that the energy loss due to frequent reheating of the distribution means and the nozzles and the denaturation of the molten resin due to reheating can be avoided to improve the molding quality. The injection system according to the present invention comprises: a distribution means having an inlet and an outlet for distribution of a molten resin supplied from an injector, and a heat transfer means; a nozzle installed at the outlet of the distribution means; and a mold disposed in contact with the nozzle, the mold having a space defined therein, wherein a first adiabatic means is disposed at a contact face between the nozzle and the mold, and the first adiabatic means is a refractory material layer that is surrounded by a boundary protector formed on a metal surface.
