The utility model provides a tradition structure cooling sizing material area heat transfer and quickening sizing material curingprocess rate little, that be difficult to between separation cold flow way high temperature heating board and the needle valve body cause the extravagant problem of material, the shaping of fecund article can be realized simultaneously, the single problem of quantity has been solved.
Description
Technical field
The utility model relates to a kind of component devices of liquid-state silicon gel cold runner injection mould, is specifically related to a kind of novel pair of screw thread spininess valve cold runner nozzle, belongs to silica gel mould technical field.
Background technology
Two screw thread spininess valve cold runner nozzle be liquid-state silicon gel cold runner injection mould vitals device, it is for being delivered to die cavity by sizing material, ensures that the cooling effect that sizing material obtains maximum area does not cause waste.
But two screw thread spininess valve cold runner nozzle film-cooled heats of traditional structure are little, and curing temperature is too high, and easily cause product starved, size less than normal, thickness is partially thick, distortion, easily breaks, and difficulty tears limit etc. open, and bad easily to cause loading higher etc. bad.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of novel pair of screw thread spininess valve cold runner nozzle, to overcome described defect of the prior art.
Utility model content
For solving the problem, it is simple that the purpose of this utility model is to provide a kind of structure, and film-cooled heat is large, can avoid novel pair of screw thread spininess valve cold runner nozzle of waste of material.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of novel pair of screw thread spininess valve cold runner nozzle, and it comprises two screw thread sprue bush, cast gate overcoat, nozzle and nozzle nut; Wherein, described pair of screw thread sprue bush inserts in cast gate overcoat, and its outer surface is provided with the first screw thread coolant flow channel and the second screw thread coolant flow channel, and described first screw thread coolant flow channel is connected with the bottom of the second screw thread coolant flow channel; Put outside described cast gate and be provided with cooling water inlet and coolant outlet, described cooling water inlet is connected with the first screw thread coolant flow channel, and described coolant outlet is connected with the second screw thread coolant flow channel; Described nozzle nut is bolted in the bottom of cast gate overcoat; Described nozzle is installed in nozzle nut, and itself and two screw thread sprue bush connect.
Novel pair of screw thread spininess valve cold runner nozzle of the present utility model is set to further: be connected by alignment pin between described pair of screw thread sprue bush and nozzle.
Compared with prior art, the utility model has following beneficial effect:
1. novel pair of screw thread spininess valve cold runner nozzle of the present utility model adopts two screw thread coolant flow channel, and the area that cooling is covered is large, and ensure that the sizing material before entering die cavity is in even normal temperature state, cooling fluid effect is good;
2. novel pair of screw thread spininess valve cold runner nozzle of the present utility model can prevent the too much solid sulfuration of sizing material, reduces unnecessary waste of material;
3. to realize multi-product shaping for novel pair of screw thread spininess valve cold runner nozzle of the present utility model, and solve quantity Single-issue, high efficiency of forming, overcomes Material Price Difference.
Accompanying drawing explanation
Fig. 1 is the three-dimensional exploded view of novel pair of screw thread spininess valve cold runner nozzle of the present utility model.
Fig. 2 is the cooling water path profile of novel pair of screw thread spininess valve cold runner nozzle of the present utility model.
Detailed description of the invention
Refer to shown in Figure of description 1 and accompanying drawing 2, the utility model is a kind of novel pair of screw thread spininess valve cold runner nozzle, and it is made up of a few parts such as two screw thread sprue bush 1, cast gate overcoat 2, nozzle 4 and nozzle nuts 3.
Wherein, described pair of screw thread cast gate 1 overlaps and inserts in cast gate overcoat 2, and its outer surface is provided with the first screw thread coolant flow channel 11 and the second screw thread coolant flow channel 12, and described first screw thread coolant flow channel 11 is connected with the bottom of the second screw thread coolant flow channel 12.
Described cast gate overcoat 2 is provided with cooling water inlet 21 and coolant outlet 22, and described cooling water inlet 21 is connected with the first screw thread coolant flow channel 11, and described coolant outlet 22 is connected with the second screw thread coolant flow channel 12.
Described nozzle nut 3 is bolted in the bottom of cast gate overcoat 2.
Described nozzle 4 is installed in nozzle nut 3, and itself and two screw thread sprue bush 1 connect.Be connected by alignment pin 5 between described pair of screw thread sprue bush 1 and nozzle 4, make both combine firmly.
The operation principle of novel pair of screw thread spininess valve cold runner nozzle of the present utility model is as follows: sizing material flows to nozzle 4 from two screw thread sprue bush 1, and the final die cavity that arrives completes injection technique.Two screw thread sprue bush 1 is embedded in cast gate overcoat 2, cooling water flows into from cooling water inlet 21, along Fig. 2 direction of arrow along first screw thread coolant flow channel 11 arrive bottom after, upwards go out along the second screw thread coolant flow channel 12 from coolant outlet 22, cast gate overcoat 2 will flow through the water body sealing of the first screw thread coolant flow channel 11 and the second screw thread coolant flow channel 12, ensure water body uniform circulation, finally under cooling promotes, sizing material arrives nozzle loading mould cavity and completes multiple product injection moulding.
Above detailed description of the invention is only the preferred embodiment of this creation, and not in order to limit this creation, any amendment made within all spirit in this creation and principle, equivalent replacement, improvement etc., within the protection domain that all should be included in this creation.
