The both ends of pipe runner are communicated with each other by connecting passage, and the input port and delivery outlet being connected with die heater are arranged at connecting passage
On；
--- the connecting passage is by the blind hole on cylinder barrel by adjacent straight tube flow passage, the cylinder both ends
End cap is set, for sealing the blind hole；
--- the runner mechanism quantity is more sets, and along the cylinder subsection setup in the inside of barrel, every suit stream
Road mechanism connects with corresponding die heater respectively；
--- the heat-conducting medium is heat-conductive water or conduction oil.
A kind of Novel heating barrel provided by the utility model compared with prior art, has advantages below：First, by
In the heating cylinder mainly by cylinder, be arranged at the runner mechanism being connected with die heater and thermocouple structure of cylinder wall inner portion
Into the closure that runner mechanism both ends are connected to circulate for heat-conducting medium by connecting passage is overall, has structure
The characteristics of simple；Second, the runner mechanism of the heating cylinder includes some straight tube streams around the distribution of cylinder axle center in barrel
Road, the both ends of adjacent straight tube runner are communicated with each other by connecting passage, and the input port and delivery outlet being connected with die heater are respectively provided with
On connecting passage, straight tube structure heat-conducting medium circulation flow rate is fast, and heat transfer efficiency is high；Third, due to the heating material
For the connecting passage of cylinder by the blind hole on cylinder barrel by adjacent straight tube flow passage, cylinder both ends set end cap to be used to seal
The blind hole, the whole runner mechanism for heat conduction is arranged on barrel wall inner portion, apart from bowl interior sizing material closer to, and
The thermal losses of heat-conducting medium substantially reduces, and has the characteristics of good heat conduction effect.
Brief description of the drawings
Fig. 1 is a kind of structural representation of Novel heating barrel of the utility model；
Fig. 2 is the structural representation of the runner mechanism in the corresponding connection in both ends of this heating cylinder.
Embodiment
Below in conjunction with the accompanying drawings the structure to a kind of Novel heating barrel provided by the utility model and operation principle make into
The detailed description of one step.
As shown in Figure 1, 2, it is a kind of structure of Novel heating barrel provided by the utility model
Schematic diagram.Form the structure of the Novel heating barrel mainly by cylinder 1, be arranged inside the barrel 2 of cylinder 1 and mould
Warm machine（Do not marked in accompanying drawing）The runner mechanism 3 and thermocouple 4 of connection are formed, wherein, the both ends of runner mechanism 3 pass through connecting passage
31 closures for being connected to circulate for heat-conducting medium are overall.
Its operation principle is：After adding sizing material in barrel, the runner mechanism 3 being placed in barrel barrel 2 is full of heat-conducting medium,
Due to the connecting passage 31 at its both ends, to be connected closure as circulating for heat-conducting medium overall, thus heat-conducting medium away from
From sizing material closer to transmission thermal efficiency is higher, and thermal loss is smaller, and thermocouple 4 is placed in the temperature of the internal-response sizing material of barrel 2 more
It is accurate to add, and die heater control temperature is much sooner.
In a kind of above-mentioned structure of Novel heating barrel is formed,
--- above-mentioned runner mechanism 3 includes some straight tube runners 32 around the distribution of the axle center of cylinder 1 in barrel 2, adjacent
The both ends of straight tube runner 32 are communicated with each other by connecting passage 31, and the input port 51 and delivery outlet 52 being connected with die heater are respectively provided with
On connecting passage 31；Wherein, according to setting, the quantity of straight tube runner 32 is different, and the setting of input port 51, delivery outlet 52 also has
There is different distribution modes：When the quantity of straight tube runner 32 is even number, input port 51 and delivery outlet 52 are distributed in barrel simultaneously
Same one end；When the quantity of straight tube runner 32 is odd number, input port 51 and delivery outlet 52 are distributed in the both ends of barrel respectively.
--- in order to reduce the thermal loss of heat-conducting medium, above-mentioned connecting passage 31 passes through the blind hole on the barrel 2 of cylinder 1
6 connect adjacent straight tube runner 32, and the both ends of cylinder 1 are provided for sealing the end cap of blind hole 6, and therefore, whole runner mechanism 3 is all
It is placed in inside the barrel 2 of heating cylinder, heat conduction is abundant and heat transfer speed is fast；
--- in order to realize that heating cylinder is segmented independent control temperature, the above-mentioned quantity of runner mechanism 3 is more sets, and along cylinder
1 subsection setup connects with corresponding die heater respectively in the inside of barrel 2, every suit runner mechanism 3, can be divided into heating
Area, plasticizing zone and constant temperature storing area, realize different temperatures independent control, meet fine injection moulding and require；
--- heat-conducting medium is returned in die heater after runner mechanism 3 comes out, and heat temperature raising is carried out by die heater,
When the temperature in the barrel that thermocouple 4 detects reaches setting value, die heater is stopped, when temperature is less than setting value,
Die heater begins to warm up heating, after temperature reaches setting value, is stopped, so moves in circles again.Above-mentioned heat-conducting medium is
Heat-conductive water or conduction oil, because the heat transfer coefficient of conduction oil only has the 1/3 of water, therefore heat-conductive water are used as heat-conducting medium
There is its advantage, i.e. the conduction efficiency of water is high, and pollution is few, and resource easily obtains, when temperature is higher than 90 DEG C, the heat transfer of water
Property it is well more many than the oil under synthermal, therefore with prominent high temperature operation capability, but the temperature heated is well below oil temperature
Machine, when design temperature is more than 150 DEG C, conduction oil is preferably used for security consideration, when heating cylinder carries out being segmented independent temperature
During degree control, two ways is used in combination, met to sizing material heating, plasticizing, the different temperatures requirement of constant temperature storing.
