Have it is multiple go out cast gates, it is described go out cast gate be connected to corresponding sharp-tongued runner, multiple cast gate phases out corresponding with each sharp-tongued runner
The axis of corresponding sharp-tongued runner is circumferentially uniformly arranged.
It preferably, further include the multiple needles for being separately positioned on corresponding nozzle flow channel and sharp-tongued runner.
Preferably, one end of the sharp-tongued separate nozzle flow channel of bull and be located at nozzle flow channel axis on be provided with needle
One end of pilot hole, the needle is arranged in needle pilot hole.
Preferably, the sharp-tongued one end of the close bull of the nozzle body is provided with trench structure, and the bull is sharp-tongued
In the trench structure that one end is inserted into.
Preferably, it is provided in one end of the sharp-tongued close nozzle flow channel of bull and extends radially outwardly along bull is sharp-tongued
Bulge loop, be arranged with cast gate department in one end of the sharp-tongued separate bulge loop of bull, one end of the cast gate department is inserted into the groove profile
It in structure and is resisted against on the end face of bulge loop, the outer surface of the cast gate department and the inner surface of trench structure are threadedly engaged.
Preferably, having heaters is installed in the outside of nozzle body.
Compared with prior art, which has the advantages that
The hot runner system is sharp-tongued using bull, and bull is sharp-tongued while having multiple sharp-tongued runners, passes through multiple sharp-tongued streams
Road can satisfy some the case where needing multiple spot while being poured, and can especially apply in the lesser occasion of die size, simultaneously
The case where relative to multiple common flow passages are mounted together, the sharp-tongued installation of the bull is simpler, can reach higher peace
Fill precision.

Preferred embodiment in stating is only used as illustrating, it may occur to persons skilled in the art that other obvious modifications.
As shown in Figs 1-4, a kind of hot runner system, it is sharp-tongued including nozzle body 1 and the bull being mounted in nozzle body 1
3, it is provided with multiple nozzle flow channels 11 in the nozzle body 1, is provided in the bull sharp-tongued 3 same with nozzle flow channel 11
Equal number of sharp-tongued runners 31, the nozzle flow channel 11 are aligned one by one with sharp-tongued runner 31, and what is flowed out in this way from nozzle body 1 is molten
The plastic cement melted is able to enter in sharp-tongued runner 31 by nozzle flow channel 11.Preferably, the quantity of sharp-tongued runner 31 is four.
The bull sharp-tongued 3 structure cylindrical, multiple sharp-tongued runners 31 extend simultaneously along the axis direction of bull sharp-tongued 3
And the axis relative to bull sharp-tongued 3 is evenly provided on same circumference.The one of the separate nozzle flow channel 11 of bull sharp-tongued 3
Be provided at end and the position of corresponding each sharp-tongued runner 31 it is multiple go out cast gates 32, it is described go out cast gate 32 and corresponding sharp-tongued stream
Road 31 is connected to.Corresponding each sharp-tongued runner 31 it is multiple go out cast gates 32 relative to corresponding sharp-tongued runner 31 axis circumferentially
Be uniformly arranged, and each go out cast gate 32 along the flow direction of plastics at a distance from the axis of corresponding sharp-tongued runner 31 gradually
Increase.
Needle is provided on one end in the separate nozzle flow channel 1 of bull sharp-tongued 3 and the axis positioned at nozzle flow channel 11 to lead
To hole 33, needle 5, one end of the separate nozzle body 1 of needle 5 are provided on the axis of nozzle flow channel 1 and sharp-tongued runner 31
