Title:
NOZZLE UNIT STRUCTURE FOR INJECTION MOLDING MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/225956
Kind Code:
A1
Abstract:
The present invention relates to a nozzle unit structure for an injection molding machine, which minimizes resin remaining in a nozzle unit during a process of injection molding and enables gas to be smoothly discharged. Since a molten material flowing into an injection machine passes through a connecting body of the injection machine and escapes only through a movement groove of a filter body from a gas filter installed in a flow channel body, the molten material remaining in a flow channel is minimized. Moreover, gas, which is generated while the molten material escapes through the movement groove, moves into a flow channel groove through a gap between washers and is smoothly discharged through a gas discharge channel in communication with the flow channel groove, so that the flow channel body is prevented from being destroyed or exploding due to stagnation of gas.
