Abstract
The utility model discloses a split type hot nozzle which comprises a suspending table, a nozzle body and a nozzle head. The suspending table is arranged on a template; the upper end part of the nozzle body is sleeved and suspended inside the suspending table and is embedded in a mounting cavity of the template, and the lower end part of the nozzle body is provided with a distribution hole communicated from a hot runner to the lower end surface of the nozzle body; and the nozzle head is sleeved on the periphery of the lower part of the nozzle body. Compared with the prior art, the split type hot nozzle disclosed by the utility model has the advantages that the suspending table and the nozzle body are two independent components, and the suspending table is made from materials with poor thermal conductivity so that the thermal transfer from the nozzle body to the template is reduced; and the nozzle body and a nozzle core are of an integrated structure so that the transfer of the heat of the nozzle body to a die is prevented and the temperature of the nozzle body can be directly transferred to the lower end part of the nozzle body; and therefore, the temperature of the lower end part of the nozzle body is increased and a sizing material is prevented from being condensed.
Description
Technical field
The utility model relates to the hot runner mould technical field, is specifically related to a kind of split type hot mouth.
Background technology
Hot runner plastic injection mould is the injection mold that generally adopts in the plastic cement processing industry, the hot mouth that it generally includes runner plate and is positioned at the runner plate end, as shown in Figure 1, be a kind of hot mouth structure that generally adopts of present stage, its mouth body 15 is two individual part with mouth core 16, between mouth body 15 and the mouth core 16 because there being fit clearance, cause thermal loss, mouth core 16 is nearer with mould template 19 surface distances, the thermal loss of mouth core 16 is larger, the drop in temperature of mouth core 16 is obvious, and runner 21 interior melten gel temperature are difficult to be protected, and may cause the situation of cold glue to occur.In addition, mouth body 15 is an integral body with hanging platform, makes mouth body 15 processing technologys complicated, and cost is higher; Hanging platform directly contacts with template 19, causes more thermal loss, thereby affects mold temperature.
The utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of split type hot mouth, avoids the generation of cold glue phenomenon, reduces simultaneously the thermal loss of mouth body.
For achieving the above object, the utility model adopts following technical scheme:
A kind of split type hot mouth comprises,
Hanging platform, it is installed on the template;
The mouth body, hanging platform inside is inserted in and is mounted in its upper end, and be embedded in the installation cavity of template, and the bottom of mouth body has by the tap hole of its hot flow path conducting to the lower surface;
Mouth is linked in the lower, outer perimeter edge of mouth body.
The bottom of mouth is stuck in the bottom of installation cavity, the inwall bottom of mouth has the first depressed part, this first depressed part and mouth body lower surface form the first gap, and the outer surface bottom of mouth has the second depressed part, and the inwall of this second depressed part and installation cavity forms the second gap.
The upper inside wall of mouth is offered internal thread, and mouth body outer setting has a protuberance, and this protuberance outer surface is offered the external screw thread with the internal thread coupling.
The part of mouth inwall between internal thread and the first depressed part forms a mating surface, and this mating surface and mouth body outer wall are positioned at the wall of protuberance bottom and fit.
The outer cover of mouth body is provided with the heating circle.
Form a gap between hanging platform and the template.
The beneficial effects of the utility model are:
Than prior art, hanging platform of the present utility model and mouth can adopt the relatively poor material of thermal conductivity to make hanging platform as two parts independently, reduce by the heat transmission of mouth body to template; Mouth body and mouth core are structure as a whole, and have avoided mouth body heat to the mould transmission, and mouth body temperature can be directly passed to its bottom simultaneously, improves the temperature of its bottom, prevents the sizing material condensation.

The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
Shown in Fig. 2,3, be a kind of split type hot mouth of the utility model, it comprises hanging platform 1, mouth body 2, mouth 4; From existing different, the bottom of mouth body 2 has by the tap hole of its hot flow path conducting to the lower surface, to substitute mouth core of the prior art, can think, mouth core and mouth body 2 are structure as a whole, and in fact the bottom of mouth body 2 is equal to the mouth core.Mouth 4 directly is linked in the bottom outer peripheral edges of mouth body 2; Hanging platform 1 is installed on the template 5, and the part that its outer peripheral edges cooperate with template 5 forms a gap 51.The upper end of mouth body 2 is enclosed within hanging platform 1 inside, and top is mounted on the hanging platform 1 on it, the part that mouth body 2 is passed by hanging platform 1 is embedded in the installation cavity 52 of template 5, the bottom of mouth 4 is snap-fit at narrower position, installation cavity 52 bottoms, and mouth 4 bottom outer walls form a depressed part 44 over against the part of installation cavity 52 inwalls, this depressed part 44 and installation cavity 52 over against inwall between form a gap, the inwall bottom of mouth 4 has a depressed part 43, this depressed part 43 forms a gap with the outer surface of mouth body 2 bottoms, and above-mentioned depressed part 44 and depressed part 43 all extend downward the lower surface of mouth body 2.
Above-mentioned mouth body 2 and hanging platform 1 are two independently parts, its the two work in coordination, and the installation of realization mouth body 2 and template 5, so, can be so that mouth body 2 directly contact with template 5, hanging platform 1 selects the relatively poor material of thermal conductivity to be made, and effectively stops heat 5 transmission from mouth body 2 to template, reduce thermal loss, avoided simultaneously the impact on template 5 temperature; And hanging platform 1 is simple in structure, and convenient processing can be applicable to different mouth bodies 2, has stronger interchangeability.Between hanging platform 1 and the template 5 gap 51 is set, this gap 51 can be to offer an avoiding hollow groove at hanging platform 1 outer surface to form, and it has reduced the contact area of hanging platform 1 with template 5, has further reduced hot transmission, reduce thermal loss, make the temperature of hot flow path inside more uniform and stable.
Owing to depressed part 43 and depressed part 44 being set on the mouth 4, reduced the contact area with template 5 and mouth body 2, reduced thermal losses, reduced near the temperature the mould gate, improved the thermal efficiency of hot mouth.
In the said structure, mouth body 2 adopts threaded engagement with mouth 4, and concrete is, mouth 4 upper inside wall are offered internal thread 41, and mouth body 2 outsides have a protuberance 21, and these protuberance 21 outer surfaces offer external screw thread 22, external screw thread 22 and internal thread 41 couplings are fixed together mouth 4 and mouth body 2.The part of the inwall of mouth 4 between internal thread 41 and depressed part 43 protruded and formed a mating surface 42, this mating surface 42 is fitted with the wall 23 that mouth body 2 outer walls are positioned at protuberance 21 bottoms, mouth body 2 is positioned at the external diameter at wall 23 places, the internal diameter that is positioned at mating surface 42 places with mouth 4 is suitable, so, for the assembling of mouth body 2 with mouth 4, provide good guide-localization, prevented that screw thread from damaging because of thermal deformation, made the mouth 4 can the secondary utilization.
The outer cover of mouth body 2 is provided with heating circle 3, with thinking that the hot flow path in the mouth body 2 provides enough heats.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion should belong within the protection domain of the utility model claim all.
