Detailed description of the invention
Core of the present utility model is to provide a kind of injector assembly, and the disassembly process of this injector assembly is simple and easy to do, and its operation and maintenance cost is lower; Meanwhile, a kind of injection machine applying said nozzle assembly is provided.
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 1, Fig. 2 and Fig. 3, the structural representation of the nozzle body part of the injector assembly that Fig. 1 provides for a kind of detailed description of the invention of the utility model; The structural representation of the nozzle head part of the injector assembly that Fig. 2 provides for a kind of detailed description of the invention of the utility model; Fig. 3 is the structural representation in A-A face in Fig. 2.
In a specific embodiment, injector assembly provided by the utility model, comprise nozzle body 11, the middle part of nozzle body 11 is axially run through along it feeder channel 111, there is nozzle head 12 leading section of nozzle body 11 removably screw threads for fastening, the injection channel 121 having and be connected with feeder channel 111 is run through at the middle part of nozzle head 12, and the leading section of nozzle head 12 has the material spray cambered surface 122 suitable with die gate casing.
The nozzle body 11 adopting split type screw threads for fastening removably to coordinate and nozzle head 12, make in equipment use process, when leaking the phenomenons such as material or obstruction if occur, only need nozzle head 12 to unload separately to repair or replace, without the need to injector assembly entirety is pulled down, thus enormously simplify associated components unloading process, reduce the maintenance difficulties of injector assembly, and make the corresponding reduction of the labour intensity of staff, the corresponding raising of operating efficiency, effectively reduces overall use cost and the maintenance cost of injector assembly and injection machine simultaneously.
Further, the radius of material spray cambered surface 122 is 13 millimeters.The material spray cambered surface 122 of this kind of dimensions can be mated completely with the die gate casing of standard, thus effectively prevent the phenomenons such as the leakage material caused because nozzle head specification is not mated with sprue bush specification.
More specifically, the hardness of nozzle body 11 and nozzle head 12 is Rockwell hardness HRC48 ~ 52.The nozzle body 11 of this kind of hardness specification and nozzle head 12 effectively can avoid in nozzle head 12 and sprue bush contact process that sprue bush that is that cause damages phenomenon because the hardness of nozzle head 12 is excessive.
