Description

Open big mouth of a river hot runner mould

Technical field:

The utility model relates to mechanical equipment technical field, refers in particular to a kind of open big mouth of a river hot runner mould.

Background technology:

Hot runner mould is a kind of injection molding mould at present commonly used, and it is with respect to the mould of cold runner structure, has to economize in raw materials, and can enhance productivity, and improves product quality, simplifies plurality of advantages such as product subsequent handling.Though hot runner mould has above-mentioned plurality of advantages, also there is certain deficiency in it.For example, when making the bigger product of feed rate, present hot runner mould just can't adapt to, and causes product injection time slow, influences production efficiency of products and quality.

The utility model content:

Technical problem to be solved in the utility model overcomes the shortcoming of present product exactly, and a kind of open big mouth of a river hot runner mould that is applicable to that inlet amount is bigger is provided.

For solving the problems of the technologies described above, the utility model has adopted following technical scheme: it comprises flow distribution plate, hot mouth and hot mouth heater, wherein hot mouth and flow distribution plate relative fixed, and the interior runner of the runner in the flow distribution plate and hot mouth is communicated with, hot mouth heater is fixed in hot mouth outside, and described Re Zui end is provided with a cast gate department that is communicated with its runner.

Described hot mouth heater comprises: heater and sleeve, heaters set are located on the hot mouth body, and sleeve is placed in outside the heater, promptly in the gap that heater forms between sleeve and hot mouth body.

Described hot mouth heater also comprises the temperature detector of a sensing heater.

Described hot mouth comprises: hot mouth body and sharp-tongued, hot mouth body and flow distribution plate are fixed, the sharp-tongued cavity that is positioned at hot mouth body lower end that is arranged at, described cast gate department upper end be sheathed on sharp-tongued on.

Described cast gate department and sharp-tongued port are less than the outlet of its end.

When using the utility model, the liquid charging stock of fusion will at first enter flow distribution plate, enter in the runner in each hot mouth on the flow distribution plate by the runner in the flow distribution plate again, and heater makes raw material remain on molten condition.Externally under the pressure effect, raw material is by runner, sharp-tongued, cast gate department outflow.Cast gate department can directly be connected (for example when the bigger product of moulding) with the cast gate of formed product mould, also can by flow distribution plate raw material be shunted again, is divided into some branch cast gates.Stability Analysis of Structures of the present utility model, reasonable in design, not only can be directly used in the product that the shaping raw material flow is big, volume is bigger, and can be used to make the product of other general requirements by the flow distribution plate shunting.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is an internal structure cutaway view of the present utility model.

The specific embodiment:

See Fig. 1, the utility model is an open big mouth of a river hot runner mould, and it mainly comprises: flow distribution plate 1, hot mouth 2 and hot mouth heater 3.Wherein hot mouth 2 and flow distribution plate 1 relative fixed, and the runner 10 in the flow distribution plate 1 is communicated with runner 20 in the hot mouth 2, and the raw material of fusion enters in the hot mouth 2 by flow distribution plate 1 after heating.Certainly, a flow distribution plate 1 can connect a plurality of hot mouths 2, and raw material enters in each hot mouth 2 by flow distribution plate.

Hot mouth 2 comprises: hot mouth body 21, sharp-tongued 22 and cast gate department 23.Hot mouth body 21 is fixing with flow distribution plate 1, forms runner 20 in it, and the end face setting that hot mouth body 21 contacts with flow distribution plate 21 is by sealing ring 24.Sharp-tongued 22 are arranged at the end of hot mouth body 21 inner flow passages 20, promptly are formed with a cavity in the lower end of hot mouth body 21 runners, and sharp-tongued 22 are arranged in this cavity, and passage and runner 20 conductings in sharp-tongued 22.The outlet of sharp-tongued 22 end is communicated with cast gate department 23, raw material by circulation 20 through sharp-tongued 22, cast gate department 23 outflows.Cast gate department 23 upper ends are a sleeve pipe, and it is sheathed on sharp-tongued 22.The bottom of cast gate department 23 is one section conduit, and the outflow of raw material is convenient to, augmented flow like this in this conduit upper end and the outlet 232 of sharp-tongued 22 ports that are communicated with 231 less than its end.

Hot mouth heater 3 is fixed in hot mouth 2 outsides, and this heater 3 comprises: heater 31, sleeve 32 and temperature detector 33.Heater 31 is sheathed on the hot mouth body 21, and sleeve 32 is placed in outside the heater 31, promptly in the gap that heater 31 forms between sleeve 32 and hot mouth body 21.Heater 31 is generally electric calorifie installation, and sleeve 32 is used for heat insulation and the protection electric calorifie installation.Temperature detector 33 is used to monitor the temperature of heater 31, remains on suitable temperature with the temperature that makes hot mouth body 21.

When using this use the utility model, the liquid charging stock of fusion will at first enter flow distribution plate 1, and in the runner 20 in runner 10 each the hot mouth 2 on entering flow distribution plate in the flow distribution plate 1, heater 3 makes raw material remain on molten condition.Externally under the pressure effect, raw material is by runner 20, sharp-tongued 22, cast gate department 23 outflows.Cast gate department 23 can directly be connected (for example when the bigger product of moulding) with the cast gate of formed product mould, also can by flow distribution plate raw material be shunted again, is divided into some branch cast gates.

Stability Analysis of Structures of the present utility model, reasonable in design, not only can be directly used in the product that the shaping raw material flow is big, volume is bigger, and can be used to make the product of other general requirements by the flow distribution plate shunting.

Certainly, the above only is example of the utility model, be not to limit the utility model practical range, all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
