Specific embodiment
The utility model is described in further details with reference to the accompanying drawings and detailed description.
As Figure 1-Figure 4, in an injection mold, the injection mold includes upper die plate to the utility model embodiment one
10th, lower template 20, generally within die cavity therebetween, the sprue portion 3 of the present embodiment one is substantially then the present embodiment one
Through upper die plate 10.For the present embodiment one, it mainly includes sprue portion 3, distributary division 4, cover plate 5.Need to illustrate in advance
, it is dismountable annexation between each critical piece of the present embodiment one, in other embodiments, at least two is adjacent
Can also be structure as a whole between part.
Wherein, then as shown in Figure 6, Figure 7, sprue portion 3 is in the form of a column, and is alongst provided with for by molten plastic
Sprue 31 and for the first heating flow channel 32 by deep fat.
Again as shown in Figure 8, Figure 9, distributary division 4 is plate-like, is provided with the runner 42 of at least one flute profile, and be provided with second plus
Hot flow path 41, similarly, the second heating flow channel 41 is also for water conservancy diversion deep fat.
Again as shown in Figure 10, cover plate 5 is covered on runner 42, and the runner 51 of flute profile also is provided with cover plate 5, with
The correspondence of runner 42, to expand flow.If there is the accidents such as blocking during production, opening cover plate 5 can clear up sprue 31 and divide
Improper molten plastic on runner 42, runner 51.
Also, distributary division 4 is provided with hot mouth cast gate 7, it is easy to connect hot mouth, hot mouth cast gate 7 is connected with runner 42；It is preferred that
Ground, hot mouth cast gate 7 is provided with internal thread, is threadedly coupled with hot mouth, and according to hot mouth needs, hot mouth cast gate 7 can be straight mouth cast gate
