Description
Technical field
This utility model is related to a kind of hot-runner nozzle, more particularly, to a kind of hot-runner nozzle head core.
Background technology
Hot flow path is to ensure that runner and the plastics of cast gate are kept molten by by the method for heating.TOP-TIP one
As be made up of a few part such as hot nozzle, flow distribution plate, temperature control box and adnexa.Wherein hot-runner nozzle generally comprises main body, heating collar
And spreader.In the prior art, spreader is arranged at body front end, and spreader is conical structure, the glue spraying mouth of spreader
It is arranged on taper seat, due to taper seat linearly, spreader inserts in mold runner, and its plastic emitting area is little, lead to plastic emitting speed
Degree is slow, the effect of impact product injection mo(u)lding.
Content of the invention
This utility model purpose is to provide a kind of hot-runner nozzle head core, by using this structure, improves hot flow path spray
The plastic emitting speed of mouth.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is：A kind of hot-runner nozzle head core, including this
Body, described bodies top is provided with conical head core, and on described conical head core, annular is evenly equipped with a plurality of glue spraying mouths, described conical head core
Outer edge surface in the middle part of be provided with the arc groove of a ring-type, described glue spraying mouth is arranged in described arc groove, described arc groove
Radius be 30～120.
In technique scheme, described is additionally provided with runner in vivo, and described runner is connected with described glue spraying mouth.
In technique scheme, the top of described body is provided with conical head core, and the bottom of described body is provided with a convex annular
Platform.
Because technique scheme is used, this utility model compared with prior art has following advantages：
1. in the middle part of the outer edge surface of described conical head core, in this utility model, it is provided with the arc groove of a ring-type, described glue spraying
Mouth is arranged in described arc groove, and the radius of described arc groove is 30～120, by the setting of arc groove, and
Glue spraying mouth is arranged in described arc groove, makes glue spraying mouth have a larger glue spraying position of area in glue spraying, simultaneously for
Arc groove, arcuate structure, plastic emitting is more smooth, improves the glue spraying efficiency of hot-runner nozzle, injecting products are effectively ensured
Injection quality and injection stability；
2. this utility model structure is simple, it is easy to accomplish.
Brief description
Fig. 1 is the structural representation in this utility model embodiment one.
Wherein：1st, body；2nd, conical head core；3rd, glue spraying mouth；4th, arc groove；5th, runner；6th, annular boss.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to this utility model：
Embodiment one：Shown in Figure 1, a kind of hot-runner nozzle head core, including body 1, described body 1 top is provided with cone
Forming head core 2, on described conical head core 2, annular is evenly equipped with a plurality of glue spraying mouths 3, is provided with the middle part of the outer edge surface of described conical head core 2
The arc groove 4 of one ring-type, the side of described arc groove 4 is connected with the top of described conical head core 2, opposite side with described
The outside of body 1 is connected, and described glue spraying mouth 3 is arranged in recessed 4 grooves of described arc, and the radius of described arc groove 4 is 60.
In conventional structure, glue spraying mouth is directly arranged on the taper surface of conical head core, because taper surface is a straight line
Plane, conical head core inserts in mold runner, is in an acute angle between taper surface and mold runner, the plastic cement stream that glue spraying mouth sprays
In acute angle, acuter angles can affect glue spraying efficiency.Therefore, in the present embodiment, arc groove is set, glue spraying mouth is arranged at
In arc groove, arc groove increased the area between conical head core and mold runner first, is easy to the flowing of plastic cement, its
Secondary, plastic cement that glue spraying mouth the gushes out arcwall face by arc groove, arcwall face is easy to the flowing of plastic cement, improves plastic emitting effect
Rate it is ensured that the injection quality of injecting products and injection stability.
Shown in Figure 1, it is additionally provided with runner 5 in described body 1, described runner 5 is connected with described glue spraying mouth 3.Runner 5
For being connected with flow distribution plate, for receiving plastic cement.
Referring to described in Fig. 1, the top of described body 1 is provided with conical head core 2, and the bottom of described body 1 is provided with a convex annular
Platform 6.The setting of annular boss, for being installed on hot-runner nozzle by body.
Claims (3)
