Abstract
A kind of hot runner hot mouth, is characterized in that: this hot mouth is a copper hot mouth, it has installation end and enters glue end; Entering glue end is four-prism shape, and is equipped with concave surface on four sides entering glue end and end face; And being provided with concave station between adjacent two sides and at the position near installation end, the position away from installation end forms a corner, and four corners all offer the glue feeding opening with the intercommunication of hot mouth sprue.The utility model is applied in hot flow path technique, and this hot mouth does not need to be set with heating circle again, causes heating circle to burn the problem of hot mouth, extend the service life of hot mouth, improve the production efficiency of enterprise without the need to worry because of the glue that overflows; And there is easy processing, low cost and other advantages.
Description
Technical field
The utility model relates to hot flow path cast field, particularly a kind of hot runner hot mouth.
Background technology
Hot flow path refers to that the plastic raw materials being sent to cast gate from nozzle of injector remains molten condition, and do not need solidification to take out as waste material when each die sinking, the melt be trapped in running gate system can be injected into die cavity when injecting again.In whole production process, when plastic material is by filling with mouth, first to enters in heating board and carrying out just carrying out injecting glue by hot mouth after insulation is shunted, its objective is before plastic material enters die cavity it must is the state of melting.And existing hot mouth is the hot mouth of S136 structural section, large and the rapid heat dissipation of the hard difficulty of processing of this hot mouth matter, the state of technical staff in order to make plastic material also can keep melting in hot mouth, present way is on hot mouth, be set with a heating circle, so just plastic material must be enclosed in below heating circle, namely closed-loop place must closely cooperate with die cavity.In order to reach above-mentioned requirements, technical staff just needs the machining accuracy improving die cavity, otherwise glue phenomenon of overflowing appears in the position that will contact with die cavity at hot mouth, and then makes plastic material immerse in heating circle, thus make the short circuit of heating circle burn whole hot mouth, finally have impact on the normal work of hot mouth.If select to keep in repair, not only need the heating circle more renewed, drop into manpower and materials, but also greatly can reduce production efficiency, and then add the input of entreprise cost.
Utility model content
The purpose of this utility model is to provide a kind of hot runner hot mouth, and object is to solve the problems of the technologies described above, and provides a kind of easy processing, cost is low and does not need the hot runner hot mouth that suit heating is enclosed.
The technical scheme that the utility model technical solution problem adopts is:
A kind of hot runner hot mouth, this hot mouth is a copper hot mouth, and it has installation end and enters glue end; Entering glue end is four-prism shape, and is equipped with concave surface on four sides entering glue end and end face; And being provided with concave station between adjacent two sides and at the position near installation end, the position away from installation end forms a corner, and four corners all offer the glue feeding opening with the intercommunication of hot mouth sprue.
By implementing the hot runner hot mouth that technique scheme obtains, its thermal conductivity is very good, and enter glue end upper recess surface, contact surface that the design in concave station and corner greatly can reduce hot mouth and die cavity, thus make this hot mouth not only can absorb heat on heating board in time, but also can accumulate in absorbing the heat come fully on this hot mouth, thus no longer need suit heating circle that the plastic material in hot mouth also can be made to keep in the molten state.Meanwhile, the soft easy processing of this hot mouth matter, general producer all can process the producer without the need to specialty.Therefore, the utility model not only has the advantages such as cost is low, easy processing, and does not need to be set with heating circle again, causes heating circle to burn the problem of hot mouth, extend the service life of hot mouth, improve the production efficiency of enterprise without the need to worry because of the glue that overflows.
Preferred as above-mentioned copper hot mouth, this hot mouth is the hot mouth of red metal.
As the further improvement of technique scheme, there is insulating collar entering on glue end cover.So just can maximize and realize hot mouth and " zero contacts " between die cavity, avoid too much being spread by die cavity of heat, thus make hot mouth gather more heat.
Preferred as above-mentioned insulating collar, this insulating collar is titanium alloy insulating collar.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model;
Fig. 2 is sectional view of the present utility model;
Fig. 3 is using state figure of the present utility model.
In figure: 1. hot mouth, 2. insulating collar, 3. heating board, 4. housing, 11. installation ends, 12. enter glue end, 13. hot mouth sprues, 31. heating board runners, 121. concave surfaces, 122. corners, 123. concave stations, 1221. glue feeding openings.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1 to Figure 3, a kind of hot runner hot mouth, this hot mouth 1 is a copper hot mouth, and it can be the copper hot mouths such as the hot mouth of red copper, the hot mouth of beryllium copper, bronze hot mouth, and this programme employing is the hot mouth of red metal.
This hot mouth 1 integrative-structure, is divided into installation end 11 and enters glue end 12 two positions.Installation end 11 is one discoid, is convenient to large area absorbs heat for being connected with heating board 3.And enter glue end 12 in four-prism shape, and on four sides entering glue end 12 and end face, be equipped with concave surface 121, and be provided with concave station 123 between adjacent two sides and at the position near installation end 11, position away from installation end 11 forms a corner 122, and four corners 122 all offer the glue feeding opening 1221 with the intercommunication of hot mouth sprue 13.
Enter glue end 12 upper recess surface 121, volume, radiating surface and the contact surface with die cavity that the design in concave station 123 and corner 122 greatly can reduce hot mouth 1, thus make this hot mouth 1 not only can absorb heat on heating board 3 in time, but also can accumulate in absorbing the heat come fully on this hot mouth 1, thus no longer need suit heating circle that the plastic material in hot mouth 1 also can be made to keep in the molten state.
In use, be closely fixed on heating board 3 by this hot mouth 1, its hot mouth sprue 13 keeps intercommunication with heating board runner 31.More heat can be gathered by heating board 3 in order to ensure this hot mouth 1, insulating collar 2 can also be had at the cover on glue end 12 that enters of hot mouth 1.Meanwhile, in order to heating board 3 can be allowed also to gather heat, also can an insulating collar 2 be set between housing 4 and heating board 3.Wherein, insulating collar 2 can be steel type insulating collar, fiberglass type insulating collar and composite material type insulating collar, and what adopt in this programme is titanium alloy insulating collar.
