Description
Technical field
The utility model relates to injection mold field, relates in particular to a kind of hot runner mould.
Background technology
At present, for injection mold, that hot flow path is more and more widely used in is high-accuracy, in the mould of cavity, but due to the problem of this body structure of hot flow path and size, cause its cost higher, and can not meet its requirement for the gate location of some miniature precision parts; And adopt traditional cold runner can produce a large amount of cold burden stub bars, cause wastage of material, and molding cycle is longer, reduce the production efficiency of product, especially for needing multiple spot to enter the product of glue, need larger injection pressure, easily cause product surface flaw, injection pressure also can shorten greatly the service life of mould simultaneously.
Utility model content
The utility model provides a kind of hot runner mould, to solve the problems of the technologies described above.
For solving the problems of the technologies described above, the utility model provides a kind of hot runner mould, comprise from top to bottom fixing successively hot runner plate, caster and male model plate, in described caster, be provided with mother module core, in male model plate, be provided with male die core, described male die core and mother module core composition, for the die cavity of formed product, are fixed with hot flow path in described hot runner plate, described hot flow path stretches in described mother module core by hot mouth, and the discharging opening of described hot mouth is communicated with described die cavity by cold runner.
Preferably, corresponding several the hot mouths that connect of described hot flow path, corresponding several cold runner that are communicated with of each hot mouth.
Preferably, the end of each cold runner is equipped with cast gate.
Preferably, described hot mouth is also provided with hot muzzle outward.
The hot runner mould that the utility model provides, comprise from top to bottom fixing successively hot runner plate, caster and male model plate, in described caster, be provided with mother module core, in male model plate, be provided with male die core, described male die core and mother module core composition are for the die cavity of formed product, in described hot runner plate, be fixed with hot flow path, described hot flow path stretches in described mother module core by hot mouth, and the discharging opening of described hot mouth is communicated with described die cavity by cold runner.The utility model is by set up cold runner between hot mouth and die cavity, and the length of reducing runner on the one hand, reduces injection pressure, improves the stability of moulding simultaneously, shortens molding cycle, and can not affect the structure of mould, makes into the layout of glue point more flexible.
Brief description of the drawings
Fig. 1 is the structural representation of the hot runner mould of the utility model one detailed description of the invention;
Fig. 2 is the top view of hot mouth and cold runner in the hot runner mould of the utility model one detailed description of the invention.
In figure: 10-hot runner plate, 20-caster, 21-mother module core, 30-male model plate, 31-male die core, 40-hot flow path, the hot mouth of 41-, 42-cold runner, the hot muzzle of 43-, 50-product.
Detailed description of the invention
For the technical scheme of the more detailed above-mentioned utility model of statement, below list specific embodiment and carry out Proof Technology effect; It is emphasized that these embodiment are not limited to limit scope of the present utility model for the utility model is described.
The hot runner mould that the utility model provides, as shown in Figure 1 to Figure 2, comprise from top to bottom fixing successively hot runner plate 10, caster 20 and male model plate 30, in described caster 20, be provided with mother module core 21, in male model plate 30, be provided with male die core 31, described male die core 31 and mother module core 21 compositions are for the die cavity of product 50 moulding, in described hot runner plate 10, be fixed with hot flow path 40, described hot flow path 40 stretches in described mother module core 21 by hot mouth 41, and the discharging opening of described hot mouth 41 is communicated with described die cavity by cold runner 42.The utility model by setting up cold runner 42 between hot mouth 41 and die cavity, after adopting hot flow path to enter glue, a point cold runner point enters glue, to merge the advantage of hot runner mould and cold runner die simultaneously, the length of reducing runner on the one hand, reduce injection pressure, improve the stability of moulding simultaneously, shorten molding cycle, and can not affect the structure of mould, make into the layout of glue point more flexible.
Preferably, ask emphasis with reference to figure 2, corresponding several the hot mouths 41 that connect of described hot flow path 40, corresponding several cold runner 42 that are communicated with of each hot mouth 41, the end of each cold runner 42 is equipped with cast gate, enters glue to realize multiple spot.
Preferably, ask emphasis with reference to figure 1, outside described hot mouth 41, be also provided with hot muzzle 43, described hot muzzle 43 mainly plays the effect of protection and supporting hot mouth 41.
In addition, after Mould Machining completes, in the situation that condition of molding need to change, also can on basis of the present utility model, increase or revise into glue position, to meet needs of production, can change controlled, convenient and practical thereby realize formed product condition.
In sum, the hot runner mould that the utility model provides, comprise from top to bottom fixing successively hot runner plate 10, caster 20 and male model plate 30, in described caster 20, be provided with mother module core 21, in male model plate 30, be provided with male die core 31, described male die core 31 and mother module core 21 compositions are for the die cavity of product 50 moulding, in described hot runner plate 10, be fixed with hot flow path 40, described hot flow path 40 stretches in described mother module core 21 by hot mouth 41, and the discharging opening of described hot mouth 41 is communicated with described die cavity by cold runner 42.The utility model is by set up cold runner 42 between hot mouth 41 and die cavity, and the length of reducing runner on the one hand, reduces injection pressure, improves the stability of moulding simultaneously, shortens molding cycle, and can not affect the structure of mould, makes into the layout of glue point more flexible.
Obviously, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model utility model.Like this, if these amendments of the present utility model and within modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model is also intended to including these changes and modification.
