Abstract
The invention discloses a hot nozzle core structure special for a black material. The hot nozzle core structure comprises a nozzle core, a flow channel through which the nozzle core is communicated with a flow channel of a hot nozzle body, and a pouring gate which is formed at the end of the nozzle core and is used for a color material to flow out, wherein a grid is arranged at the pouring gate transversely. By using the scheme, the problem that the phenomena of drawing and drooling are caused easily when the color material is extruded by using the conventional hot nozzle core special for the black material is mainly solved; and the product yield is improved.
Description
Technical field
The present invention relates to the hot mouth of hot flow path, relate in particular to the hot mouth mouth of a kind of TOP-TIP cored structure, particularly the special-purpose hot mouth mouth cored structure of black material.
Background technology
The injection mold that generally adopts in the injection moulding industry at present is the HOT RUNNER INJECTION MOULD tool; Comprise hot mouth body as the one of which; Be positioned at the runner of hot mouth body interior; Be positioned at the mouth core that communicates with runner of hot mouth body front end, be positioned at the heater of hot mouth body periphery, make the injection moulding materials and parts keep the molten condition runner of flowing through to extrude from the mouth body and carry out injection mo(u)lding through heater is installed at hot mouth body.
At present, as shown in Figure 1 to the different mouth cored structure of the normal employing of different colorants, for the special-purpose hot mouth mouth cored structure of black material, comprise mouth core 1, the runner 2 that this mouth core communicates with hot mouth body runner, the end of mouth core 1 is used for the cast gate 3 that colorant flows out.This structure makes things convenient for extruding with regard to injection mo(u)lding of black material.But this structure also comes with some shortcomings: because cast gate 3 places are straightthrough port, resistance is less, makes the black material very fast at this place's flow velocity, and colorant concentrates the big materials flow central temperature that flows out too high, is difficult for cooling, occurs serious wire drawing, hydrostomia phenomenon easily; Wire drawing, hydrostomia phenomenon seriously then can influence the pouring practice of next time, make the product fraction defective of injection mo(u)lding increase.
Therefore, how addressing the above problem, is the content that the present invention will study.
Summary of the invention
The present invention provides a kind of black material special-purpose hot mouth mouth cored structure, and its purpose mainly is to solve the special-purpose hot mouth mouth core of existing black material when extruding colorant, to occur wire drawing, hydrostomia phenomenon, the problem that causes the product fraction defective to increase easily.
For achieving the above object, the technical scheme that the present invention adopts is: the hot mouth mouth cored structure that a kind of black material is special-purpose, comprise the runner that mouth core, this mouth core communicate with hot mouth body runner, and the end of mouth core is used for the cast gate that colorant flows out; Said cast gate place laterally is provided with grid.
Related content in the technique scheme is explained as follows:
1, in the such scheme, said grid is one group of framework that parallel grizzly bar is processed.This frame-type grid is punished into several diffluence pass with cast gate.
2, in the such scheme, said grid is a grizzly bar.This grizzly bar is punished into two diffluence pass with cast gate.
3, in the such scheme, said " laterally " refers to along the direction of cast gate cross section, and corresponding " vertically " is meant the direction that sprue and runners is communicated with.
4, in the such scheme, said grid is the knife edge type grid.This knife edge type grid is divided into two in the time of can making materials flow through this place.
Because the utilization of present technique art scheme, the present invention compared with prior art has advantage:
1, because the present invention increases the knife edge type grid at the cast gate place, the framework that this knife edge type grid can be processed for one group of parallel grizzly bar also can be an independent grizzly bar; Make aniseed stream through this knife edge type grid place, be divided into two or one be divided into a plurality of materials flows that materials flow diminishes; Then materials flow is easier to cooling; Internal and external temperature is balanced, is not prone to wire drawing, hydrostomia phenomenon, has guaranteed the qualification rate of product.
2, the present invention is simple in structure, practical.
Description of drawings
Accompanying drawing 1 is a hot mouth mouth cored structure sketch map in the prior art;
Accompanying drawing 2 is used structural representation for the present invention.
In the above accompanying drawing: 1, mouth core; 2, runner; 3, cast gate; 4, grid.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Embodiment:
Hot mouth mouth cored structure as shown in Figure 2, that a kind of black material is special-purpose comprises the runner 2 that mouth core 1, this mouth core 1 communicate with hot mouth body runner, and the end of mouth core 1 is used for the cast gate 3 that colorant flows out; Said cast gate 3 places laterally are provided with grid 4.Should refer to " laterally ", with respect to " vertically " that direction became of sprue and runners connection along the direction of cast gate cross section.
This grid 4 is the knife edge type grid.Said grid 4 is one group of framework that parallel grizzly bar is processed, also can an independent grizzly bar.When said grid is one group of framework that parallel grizzly bar is processed, then this frame-type grid is punished into several diffluence pass with cast gate 3.When said grid is a grizzly bar, then this grizzly bar is punished into two diffluence pass with cast gate 3.
Because the present invention increases the knife edge type grid at the cast gate place, the framework that this knife edge type grid can be processed for one group of parallel grizzly bar also can be an independent grizzly bar; Make aniseed stream through this knife edge type grid place, be divided into two or one be divided into a plurality of materials flows that materials flow diminishes; Then materials flow is easier to cooling; Internal and external temperature is balanced, is not prone to wire drawing, hydrostomia phenomenon, has guaranteed the qualification rate of product.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
