Description
Technical field
This utility model relates to injection molding technology field, is specifically related to a kind of without splitter plate hot runner structure。
Background technology
At present, TOP-TIP owing to using in injection mold, TOP-TIP is owing to having shortening product molding cycle, save plastic raw materials, reducing waste product, improving product quality, be conducive to the production automation, expand the advantages such as injection molding process range of application, in the world today, each industrially developed country and area all obtain extremely wide application。Traditional TOP-TIP is mainly made up of nozzle, flow distribution plate and temperature controller, and a hot flow path is furnished with a flow distribution plate, and flow distribution plate is connected with nozzle。Wherein nozzle is set in corresponding mould injection port by nozzle head card to complete injection moulding process。Good being tightly connected of needs between structure, otherwise melted plastics easily spill。On the other hand, owing to the heat between nozzle head and mould transmits rapidly, owing to the lost plastic melt making nozzle head position of heat has the trend of solidification, thus causing nozzle head blocking and affecting normal injection moulding work or be prone to that wire drawing phenomenon occurs。
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide for a kind of without splitter plate hot runner structure, and this hot runner structure is formed in one, and the situation that plastics spill will not occur；Further, being furnished with multiple shunting nozzle, production efficiency is greatly improved。
For achieving the above object, this utility model adopts the following technical scheme that a kind of without splitter plate hot runner structure, including feed cavity, feed channel and at least two shunting nozzle；Described feed cavity is cone feed cavity；The center of described feed cavity is provided with discharging opening；The upper end of described feed channel is provided with feeding end, and its lower end is provided with discharge end；The discharging opening of described feed cavity connects with the feeding end of feed channel；The quantity of described discharge end is corresponding with shunting nozzle；Each discharge end described connects with each shunting nozzle；Described it is formed in one structure without splitter plate hot runner。
Realize the purpose of this utility model can also pass through to adopt the following technical scheme that and reach:
Realizing a kind of embodiment of the present utility model is: the surface of described feed cavity is additionally provided with the guiding gutter concentrated from edge to discharging opening；Described guiding gutter is evenly distributed。
Realizing a kind of embodiment of the present utility model is: the number of described shunting nozzle is three。
Realizing a kind of embodiment of the present utility model is: described shunting nozzle is evenly distributed around the center of feed channel, and each shunting nozzle is 15～25mm to the distance at feed channel center。
Realizing a kind of embodiment of the present utility model is: each shunting nozzle described is 20mm to the distance at feed channel center。
Realizing a kind of embodiment of the present utility model is: also include shower nozzle without splitter plate hot runner；The inner surface of described shower nozzle is provided with thermal insulation layer；The quantity of described shower nozzle is identical with shunting nozzle；The lower end of each shunting nozzle described is provided with a shower nozzle。
The beneficial effects of the utility model are in that:
1, hot runner structure described in the utility model is formed in one structure, it is not necessary to install flow distribution plate, the situation that plastics spill will not occur。
2, this utility model is furnished with multiple shunting nozzle, and production efficiency is greatly improved。
3, shunting nozzle of the present utility model, is evenly distributed, and pressure makes mean forced, constant product quality。
4, shower nozzle of the present utility model is provided with thermal insulation layer, and shower nozzle is without mounting heater, and when lowering molten plastic ejection, plastic melt solidifies and wire drawing phenomenon, reduces the situation of shower nozzle blocking。
5, this utility model structure simplifies, and respond well, production cost is low, and production efficiency is high。

Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:
Specific embodiment:
With reference to Fig. 1 and in conjunction with Fig. 2, the utility model discloses a kind of without splitter plate hot runner structure, including feed cavity 1,2, three shunting nozzles 3 of feed channel and three shower nozzles 4。Described feed cavity 1 is cone feed cavity；The center of described feed cavity 1 is provided with discharging opening 11；The surface of described feed cavity 1 is additionally provided with the guiding gutter 12 concentrated from edge to discharging opening 11；Described guiding gutter 12 is evenly distributed。The upper end of described feed channel 2 is provided with feeding end 21, and its lower end is provided with discharge end 22；The discharging opening 11 of described feed cavity 1 connects with the feeding end 21 of feed channel 2；The quantity of described discharge end 22 is corresponding with shunting nozzle 3；Each discharge end 22 described connects with each shunting nozzle 3。Described shunting nozzle 3 is evenly distributed around the center of feed channel 2, and each shunting nozzle 3 is 20mm to the distance at feed channel 2 center。The inner surface of described shower nozzle 4 is provided with thermal insulation layer 41；The lower end of each shunting nozzle 3 described is provided with a shower nozzle 4。Described it is formed in one structure without splitter plate hot runner。
During use, melted plastics flow into feed cavity 1, discharging opening 11 is flowed into along guiding gutter 12, through the feeding end 21 of feed channel 2, flow into shunting nozzle 3 from discharge end 22, finally flow out from shower nozzle 4 and start injection moulding, owing to shunting nozzle 3 is evenly distributed, need pressure extrusion plastic time uniform force, each shunting nozzle 3 can operate simultaneously, and production efficiency is greatly improved。Owing to not setting firing equipment on shunting nozzle 3, the inner surface at shower nozzle 4 is provided with thermal insulation layer 41, it is possible to stops plastics and extraneous heat transmission, significantly lowers solidification when spraying and wire drawing phenomenon, it is prevented that the blocking of shower nozzle 4。
For a person skilled in the art, can technical scheme as described above and design, make other various corresponding changes and deformation, and all these change and deformation all should belong within this utility model scope of the claims。
