Title:
HOT RUNNER VALVE APPARATUS FOR A MULTI-CAVITY MOLD
Document Type and Number:
WIPO Patent Application WO/2019/190295
Kind Code:
A1
Abstract:
Disclosed is a hot runner valve apparatus for a multi-cavity mold. The present invention relates to a hot runner valve apparatus for a multi-cavity mold, for enabling mass production of a high-quality injection-molded product by: improving assembly and disassembly operations by improving the coupling structure of a manifold and a nozzle; preventing, in advance, a leakage of resin caused by a gap by compensating for warping due to deformation of a connection part between a valve and the manifold caused by thermal expansion of the manifold heated to a high temperature by a heater; and maintaining a good flow of the resin.
