At present, 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。Hot flow path is to ensure that the plastics of runner and cast gate are kept molten by by the way heated。In prior art, it is directly nozzle head card is set in progressive die tool during injection moulding, owing to the contact area of nozzle head Yu mould is excessive, heat transmission between the two is 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。For the main burner of injection moulding hot runner flow distribution plate, general band heater, operationally can guarantee that the plastics in main burner are in molten condition, but cost of manufacture be higher。
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide for a kind of hot flow path with collet, and the shunting nozzle of this hot flow path is without heater, by being transmitted by the heat of flow distribution plate, keep the heat of molten plastic in shunting nozzle, keep normal injection moulding to work。
For achieving the above object, this utility model adopts the following technical scheme that
Realize the purpose of this utility model can also pass through to adopt the following technical scheme that and reach: a kind of hot runner structure with collet, including flow distribution plate, heating element heater, runner and shunting nozzle；Described heating element heater is arranged on flow distribution plate；Described runner includes charging aperture, upper runner, lower flow channel and discharging opening；Described charging aperture is through with the upper end of upper runner；Described upper runner is arranged in flow distribution plate；Described lower flow channel is through with the lower end of upper runner, and lower flow channel downwardly extends from flow distribution plate；Lower end and the discharging opening of described lower flow channel are through；Described shunting nozzle and lower flow channel interference fit；Described discharging opening is arranged on the inside of shunting nozzle；Described shunting nozzle is high heat conduction shunting nozzle；The outer wall of described shunting nozzle is also arranged with collet。
Realizing a kind of embodiment of the present utility model is: described shunting nozzle is beallon shunting nozzle。
Realizing a kind of embodiment of the present utility model is: described shunting nozzle is the shunting nozzle of heat conductivity 350～400W/ (m DEG C)。
Realizing a kind of embodiment of the present utility model is: the outside of described shunting nozzle is provided with fastener；The inner side of described collet is provided with the groove matched with fastener；Described collet is arranged on the outside of shunting nozzle in the way of clamping。
Realizing a kind of embodiment of the present utility model is: described collet is fiber glass coating or carbon fiber set。
The beneficial effects of the utility model are in that:
1. shunting nozzle heat conductivity of the present utility model is high, by the interference fit with lower flow channel, increase the contact of shunting nozzle and lower flow channel, heat transmission is carried out with flow distribution plate, maintain the temperature of shunting nozzle, making the plastics in shunting nozzle be in molten condition all the time, shunting nozzle does not need mounting heater, saves cost。
2. being additionally provided with collet outside shunting nozzle of the present utility model, further isolation heat and extraneous transmission, when lowering molten plastic ejection, plastic melt solidifies and wire drawing phenomenon, reduces the situation of blocking during work。
3. 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, a kind of hot runner structure with collet, including flow distribution plate 1, heating element heater 2 runner 3 and shunting nozzle 4；Described heating element heater 2 is arranged on flow distribution plate 1；Described runner 3 includes charging aperture 31, upper runner 32, lower flow channel 33 and discharging opening 34；Described charging aperture 31 is through with the upper end of upper runner 32；Described upper runner 32 is arranged in flow distribution plate 1；Described lower flow channel 33 is through with the lower end of upper runner 32, and lower flow channel 33 downwardly extends from flow distribution plate 1；Lower end and the discharging opening 34 of described lower flow channel 33 are through；Described shunting nozzle 4 and lower flow channel 33 interference fit；Described discharging opening 34 is arranged on the inside of shunting nozzle 4；Described shunting nozzle 4 is high heat conduction shunting nozzle 4；The outer wall of described shunting nozzle 4 is also arranged with collet 41。The outside of described shunting nozzle 4 is provided with fastener 42；The inner side of described collet 41 is provided with the groove 411 matched with fastener 42；Described collet 41 is arranged on the outside of shunting nozzle 4 in the way of clamping。Shunting nozzle 4 is beallon shunting nozzle 4；Described collet 41 is carbon fiber set。
During use, melted plastics flow into flow distribution plate 1, and the heating element heater 2 on flow distribution plate 1 makes plastics keep temperature；Plastics flow into upper runner 32 from charging aperture 31, then pass through lower flow channel 33 and flow to discharging opening 34；Lower flow channel 33 is tactile with the interior thereof of shunting nozzle 4；Discharging opening 34 is arranged on the inside of shunting nozzle 4, by lower flow channel 33, the heat of flow distribution plate 1 is delivered to shunting nozzle 4；Shunting nozzle 4 is high heat conduction beallon shunting nozzle 4 that heat conductivity is 350～400W/ (m DEG C), it is possible to receive the heat of flow distribution plate 1；Further, the outer sheath of shunting nozzle 4 is connected to carbon fiber heat insulation set 41, and heat conductivity, lower than 1W/ (m DEG C), has good effect of heat insulation。Shunting nozzle 4 does not need mounting heater, the heat that transmitted by flow distribution plate 1 and stopped plastics and extraneous heat transmission by collet 41, makes the plastics flowing into shunting nozzle 4 from runner 3 be kept molten by, it is prevented that the blocking of shunting nozzle 4。
