Traditional hot flow path electrical heating form:
The heating life-span limited, the electrical heating elements life-span of generally adopting in the hot flow path industry generally is no more than 4 years, and human factor is too much in the use procedure, improperly operation is about to cause element damage even larger production accident;
2. peripheral equipment is equipped with complicatedly, needs temperature controller, connector etc., operating personnel's technical merit is required high, and it is large to buy the peripheral equipment investment, to a certain extent to the universal inhibition that played of Hot runner Technology;
3. select the heating of various multi-form, different sizes, different installation and processing request etc. according to the hot-runner device needs of different size, increase design cost;
4. electric energy loss is large relatively, and environment, the energy are caused certain pressure, and production cost increases;
5. frequency of maintenance is high, safeguards strongly professionally, and the volume production of mould is formed certain destabilizing factor.
[summary of the invention]
For the shortcoming of prior art, the invention provides a kind of compact conformation, need not the oil temperature heating hot runner device of any electrical heating elements, this device utilizes the temperature transmission of deep fat and keeps the temperature of hot-runner device.
The present invention adopts following technical conceive: at first for guaranteeing the temperature of hot-runner device, the heating that discards tradition, the special oil temperature machine that adopts provides a kind of reliable deep fat, by the oil circuit that is arranged in runner plate and the hot nozzle that the oil of high temperature is uniform by around the runner, detect temperature in the runner by being arranged on thermocouple in runner plate and the hot nozzle again, adopt and regulate the temperature that oil temperature machine temperature is controlled sizing material in the runner.
The technical solution adopted for the present invention to solve the technical problems is: a kind of oil temperature heating hot runner device is provided, comprise and be fixed in hot nozzle body on the runner plate, described hot nozzle body center has the hot nozzle runner, it is characterized in that: on the hot nozzle body lateral surface helical form oil circuit is arranged, at this external hot nozzle overcoat that is fixed with of hot nozzle, described helical form oil circuit is communicated with external oil pipe, on the hot nozzle body heat is installed and chews thermocouple, in the joint face employing sealing ring sealing of hot nozzle body and runner plate.
Can there be the runner plate thermocouple runner periphery of runner plate.Oil pipe 7 can be the high temperature high voltage resistant oil pipe.
The present invention also is applicable to needle valve type hot nozzle when being applicable to open hot nozzle in the hot-runner device.In the needle valve type hot nozzle body, also comprise the needle in the hot nozzle runner, it adopts hydraulic pressure or air pressure and mechanical type driving apparatus to control the folding of hot nozzle cast gate.
Beneficial effect of the present invention is: compact conformation, and whole hot-runner device need not any electrical heating elements, and the heat conductivility of deep fat is stable and uniform more, without any need for traditional hot flow path temperature control system or the peripheral equipment of other types.
