Specific implementation mode
In the following, in conjunction with attached drawing and specific implementation mode, the utility model is described further, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
As shown in Figs. 1-2, the utility model discloses a kind of hot runner system, the hot runner system include main purt nozzle 10,
Flow distribution plate 20, hot nozzle 30 and fever circle 40, fever circle 40 are connect with hot nozzle 30, and fever circle 40 provides heat, main purt for hot nozzle 30
Nozzle 10 is connected to 20 both sides of flow distribution plate with hot nozzle 30, and fever circle 40 includes the first heating collar 41 and the second heating collar 42, mould
It includes cover half (not shown) and dynamic model (not shown) to have (not shown), and hot runner system is installed on opening for mold
In the (not shown) of hole, trepanning through cover half and dynamic model, hot nozzle 30 include the first nozzle body 31 and with 31 one end of the first nozzle body
Second nozzle body 32 of connection, the first nozzle body 31 are socketed on corresponding trepanning on cover half, and the second nozzle body 32 is socketed on phase on dynamic model
Corresponding trepanning, 31 other end of the first nozzle body are connect with flow distribution plate 20, and the first heating collar 41 is installed on the first nozzle body 31, and second
Heating collar 42 is installed on the second nozzle body 32, and the first heating collar 41 is corresponding with the trepanning on cover half, the second heating collar 42 with it is dynamic
Trepanning on mould is corresponding, and such design structure reduces the opening diameter on dynamic model, and the structure for effectively preventing dynamic model is dry
It relates to, 32 outer diameter of the second nozzle body is less than 31 outer diameter of the first nozzle body in the present embodiment, and the length of the second nozzle body 32 is the first nozzle body 31 length
DegreeIt can be effectively increased the intensity of entire hot nozzle 30 in this way.
By dividing hot nozzle 30 for the first nozzle body 31 and the second nozzle body 32,32 outer diameter of the second nozzle body is less than outside the first nozzle body 31
Diameter does the first nozzle body 31 slightly, on cover half corresponding trepanning do greatly, the second nozzle body 32 do it is small, the trepanning on dynamic model also do it is small, can
Effectively to avoid the constructive interference on dynamic model.
The outer diameter of the first nozzle body 31 is 27mm in the present embodiment, and the outer diameter of the second nozzle body 32 is limited to 19~25mm, first
Nozzle body 31 and the second nozzle body 32 are integrally formed, and are used as transition connection by an inclined-plane, and the first nozzle body 31 is than general hot flow path system
Nozzle body on system is thick, and such structure is primarily to increase the intensity of the first nozzle body 31, and then increase entire hot nozzle 30
Intensity.
In order to ensure that 30 intensity of hot nozzle, 30 integral diameter of hot nozzle must increase overstriking, but have on dynamic model many mold inserts and
Thimble, trepanning too conference have interference to the total of dynamic model, and the hot nozzle 30 in the present embodiment does the trepanning on cover half greatly, moves
Mould part open reduces, and ensure that upside-down mounting mould grows the strength problem of hot nozzle 30 for small pieces, has also reached trepanning
Small effect, the trepanning on dynamic model can specifically reduce 10mm or so, to solve the problems, such as that 30 trepanning of hot nozzle is limited, this reality
The outer diameter for applying the second nozzle body 32 in example is 22mm.
It is provided with first flow 21 in flow distribution plate 20, second flow channel 311, second flow channel 311 and are provided on hot nozzle 30
