Title:
INJECTION NOZZLE AND INJECTION MOLDING MACHINE
Document Type and Number:
WIPO Patent Application WO/2010/038567
Kind Code:
A1
Abstract:
An injection nozzle can be easily maintained and replaced even if adapted for injection molding using a resin material having low viscosity. An injection nozzle (16d) is configured such that fastening screws (33) and a flange section (31d) which are fixed sections are provided at positions shifted outward from the inner surface side of a cylinder (16a) in which a resin hardened by energy is made to flow. The structure prevents the resin, which has a liquid form and is contained in the cylinder (16a), from leaking to the fastening screws (33) and screw holes (32e) in the fixed section. Because the resin does not leak and harden at the fastening screws (33) and the screw holes (32e), removal of a nozzle body (31) does not become difficult. As a result, the nozzle body (31) can be easily removed, cleaned, and replaced.
