Abstract
The utility model relates to the technical field of the mechanic equipment, in particular to an opening pinpoint gate hot runner mould, which comprises a flow distribution plate, a hot nozzle and a hot nozzle heating device, wherein the hot nozzle is comparatively fixed with the flow distribution plate, while the runner in the flow distribution plate is communicated with the runner inside the hot nozzle, and the hot nozzle heating device is fixed outside the hot nozzle. The hot nozzle comprises a hot nozzle body, a nozzle tip and a gate lining. The nozzle tip is arranged at the terminal end of the runner inside the hot nozzle body, while the gate lining is sheathed at the nozzle tip, and the lining stands out of the hot nozzle body. The utility model has stable structure and rational design, which not only can reduce the heat loss, but also is beneficial to the better molding of the product.
Description
Technical field:
The utility model relates to mechanical equipment technical field, refers in particular to a kind of open some cast gate 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, its structure is simpler, influences the moulding of product.
The utility model content:
Technical problem to be solved in the utility model overcomes the shortcoming of present product exactly, and a kind of Stability Analysis of Structures is provided, and can make open some cast gate hot runner mould of the better moulding of product.
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 hot mouth comprises hot mouth body, sharp-tongued and gate bush, the sharp-tongued end that is arranged at hot mouth body inner flow passage, gate bush be sheathed on sharp-tongued on, and the lining end protrudes in hot mouth body.
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.Heater is used to keep the interior raw material of hot mouth to be in molten condition.
Described hot mouth heater also comprises the temperature detector of a sensing heater.This temperature detector is used to monitor the temperature of heater.
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, the sharp-tongued mould that enters product.The cast gate of formed product mould is directly aimed at sharp-tongued exit, and the edge of cast gate directly contacts with gate bush, to reduce the loss of heat.At last, raw material advances in the mold cavity of product under pressure, finishes injection molding operation.The utility model Stability Analysis of Structures, reasonable in design helps the better moulding of product.
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 some cast gate 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 gate bush 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.Sharp-tongued 22 end is provided with some outlets, and through sharp-tongued 22, the outlet by sharp-tongued 22 ends at last enters in the mould of product raw material by circulation 20.Gate bush 23 can adopt the bad conductor material of resistant to elevated temperatures heat to make, and it is sheathed on sharp-tongued 22, and the end 231 of lining 23 protrudes in hot mouth body 21.Like this when hot mouth 2 combines with the mould of product, hot mouth body 21 can directly not contact with mould, but directly contact with the formed product mould by lining 23 terminal 231, so just can reduce the loss of heat, and be unlikely to make the temperature of formed product mould to raise, make better moulding of product.
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, enter in the runner 20 in each hot mouth 2 on the flow distribution plate by the runner 10 in the flow distribution plate 1 again, and heater 3 makes raw material remain on molten condition.Externally under the pressure effect, raw material enters the mould of product by runner 20, sharp-tongued 22.The cast gate of formed product mould is directly aimed at sharp-tongued 22 exit, and the edge of cast gate directly contacts with gate bush 23, to reduce the loss of heat.At last, raw material advances in the mold cavity of product under pressure, finishes injection molding operation.
Stability Analysis of Structures of the present utility model, reasonable in design, and taken into full account effective utilization of the energy, be a kind of open some cast gate hot runner mould that makes the better moulding of product.
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.
