In the invention patent with the patent number CN203919583U, a one-mouth multi-head hot runner nozzle is disclosed. In this invention, a nozzle core and a sprue sleeve are installed in each nozzle body. In actual production, because the nozzle assembly is full of Flowing molten plastic and high-temperature fluid exert a large force on the nozzle core and the nozzle body, and the existing nozzle assembly is only connected by a single thread between the nozzle core and the nozzle body. With the continuous use of the equipment, the nozzle core and the nozzle body The threaded connection structure between the nozzle bodies will be deformed due to friction, resulting in damage to the connection parts, resulting in poor structural stability of the nozzle assembly and unsatisfactory service life

The invention discloses a hot runner nozzle assembly which comprises a base and an insert. A runner is arranged in the middle of the base in the axial direction of the base. The upper end of the insert is a sharp end provided with a sprue, and the sprue in the insert is communicated with the runner. A first external thread is arranged at the lower part of the insert. The insert is inserted into the runner and is connected with the base through the first external thread. The insert is also provided with a shoulder which is positioned at the upper part of the first external thread. The insert issleeved with a fixing reinforcer, the fixing reinforcer is connected with the base through threads, and the lower end of the fixing reinforcer is propped against the shoulder of the insert. The structural stability of the assembly can be improved, and the service life of the assembly can be prolonged.
Description
technical field [0001] The invention relates to the field of mold technology, in particular to a hot runner nozzle assembly. Background technique [0002] Injection mold hot runner technology is a new energy-saving and environmentally friendly injection molding technology. During the injection molding process of the hot runner, in order to ensure that the plastic remains in a molten state, it needs to be heated. [0003] Hot runner technology generally consists of several parts such as hot runner plate, spray group assembly, heating element, temperature controller and auxiliary parts. [0004] The existing nozzle assembly includes a base and a plug-in with a gate; the base is provided with a flow channel along its axial direction, and one end of the plug-in is threaded into the flow channel to connect with the base; the other end of the plug-in has a tip, The tip is provided with a gate. In the invention patent with the patent number CN203919583U, a one-mouth multi-head ho...
