Description
[technical field]
The present invention relates to the Hot runner Technology field in injection moulding apparatus, espespecially a kind of oil temperature heating hot runner device.
[background technology]
Along with the maturation day by day of injection mold technology, the development of Hot runner Technology, the factor such as energy-saving and environmental protection, safety has become the fresh target of Hot runner Technology.Its origin of heat of traditional hot-runner device all adopts electrical heating form, select the heating collar of different size, heating tube to maintain the stable of system temperature, this technology uses long history, its stability also in industry gains universal acceptance, but its shortcomings exposing to the open air out in Long-Time Service also makes up in the urgent need to a new technology.
Traditional hot flow path electrical heating form:
1. heating restricted lifetime, the electrical heating elements life-span generally adopted in hot flow path industry is generally no more than 4 years, and in use procedure, human factor is too much, and operation is improperly about to cause element to damage even larger production accident;
2. peripheral equipment is equipped with complicated, needs temperature controller, connector etc., requires high to the technical merit of operating personnel, buys peripheral equipment investment large, serves inhibition to a certain extent to the universal of Hot runner Technology;
3. need to select various multi-form, the heating of different size, different installations and processing request etc. according to the hot-runner device of different size, increase design cost;
4. electric energy loss is large relatively, causes certain pressure to environment, the energy, and production cost increases;
5. frequency of maintenance is high, safeguards strongly professional, forms certain destabilizing factor to the volume production of mould.
[summary of the invention]
For the shortcoming of prior art, the invention provides a kind of compact conformation, oil temperature heating hot runner device without the need to 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: first for ensureing the temperature of hot-runner device, the heating discarded tradition, the special oil temperature machine that adopts provides a kind of deep fat reliably, by being arranged on the oil circuit in runner plate and hot nozzle by the oil of high temperature uniformly by around runner, detect the temperature in runner by the thermocouple be arranged in runner plate and hot nozzle again, adopt the temperature regulating oil temperature machine temperature to control sizing material in runner.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of oil temperature heating hot runner device, comprise and be fixed on hot nozzle body on runner plate, described hot nozzle body center has hot nozzle runner, it is characterized in that: this outside of hot nozzle has helical form oil circuit, hot nozzle overcoat is had at hot nozzle body extenal fixation, described helical form oil circuit is communicated with external oil pipe, hot nozzle body is provided with heat and chews thermocouple, the joint face of hot nozzle body and runner plate adopts sealing ring to seal.
Can there be runner plate thermocouple the runner periphery of runner plate.Oil pipe 7 can be high temperature high voltage resistant oil pipe.
The present invention is also applicable to needle valve type hot nozzle while being applicable to the open hot nozzle in hot-runner device.In needle valve type hot nozzle body, also comprise the needle in 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 is without the need to any electrical heating elements, and the heat conductivility more stable and uniform of deep fat, without any need for the peripheral equipment of traditional hot flow path temperature control system or other types.
