Its advantages are quick heat exchange, and low energy consumption.
Description
Technical field
The invention belongs to a kind of mold temperature control system, relate in more detail a kind of by supply warm water or cold water fluid passage to mould inside, thereby heat supply promptly or heat extraction reach the mold temperature control system of controlling the mold temperature purpose.
Background technology
When using mould molding (production) plastic products generally speaking,, caused the generation of substandard products because of the mould initial temperature is too low.Mold temperature rises to behind the proper temperature when molten and moulds that temperature can rise when being injected into mould in, thereby needs to cool off the temperature that is risen, and to keep suitable temperature, so molding cycle is long, production efficiency is low.And, make fluid passage at mould inside, warm water or cold water are flowed into, thereby in suitable temperature range inner control mold temperature, such system is developed and use.
In day disclosure special permission (clear 63-128911 number) as shown in Figure 1, disclosed by cooler (11), pump, heater (14), the mold temperature control system that thermometer (21) and controller (30) are formed is measured mold temperature with thermometer, and just warm water was mobile when temperature was low, cold water is flowed, thus the control mold temperature.That is to say, stop the running of heater (14) when wanting cooling die and start cooler carrying out the water circulation, stop the running of cooler (11) when wanting heating mould and start heater (14) carrying out the water circulation, the mold temperature of being measured according to thermometer (21), with controller (30) opening magnetic valve, thus the circulation of control water.
Disclosed by heater in United States Patent (USP) 4.902.454 number, cooler, pump, temperature is taken into account the mold temperature control system that computer (controller) is formed, and its structure in essence is that the invention with day disclosure special permission (clear 63-128911 number) record is the same, it is characterized in that, just water will be through heater and cooler one of them or several shunt tributary, so though heater does not operate during cooling die, water must not pass through heater yet.
But foregoing invention also has its shortcoming, is exactly that rate of heat exchange is slower, so molding cycle is long, the use amount of warm water or cold water is many, causes the consumption of energy excessive.
Summary of the invention
The object of the present invention is to provide a kind ofly can form heat exchange rapidly, make molding cycle short, the consumption of energy is low, reaches the mold temperature control system of accurate temperature control and low defect rate.
Inventor of the present invention thinks: the slow reason of rate of heat exchange of old mold temperature control system is to be subjected to back pressure from the water that mould spills out, so flowing of water is very slow, forms bubble in pipeline.In order to improve rate of heat exchange, the inventor studies at this point, and the result has finished this invention.
In order to achieve the above object, mold temperature control system of the present invention is characterised in that: native system comprises that cooler, heater, auxiliary tank, expansion high-pressure hose, circulating pump, described auxiliary tank relax the back pressure that the recirculated water that flows into mould causes, and from recirculated water separation of air; Return the formation circulating path that is linked in sequence of auxiliary tank again by auxiliary tank, circulating pump, heater, expansion high-pressure hose, mould inside fluid passage, and on the access path between mould and the auxiliary tank, pick out a tributary along separate routes, this shunt tributary is connected to above-mentioned auxiliary tank after by cooler, thereby forms following two kinds of water periodic duty processes:
(1), during heating mould, the path circulation that warm water is linked in sequence like this by return auxiliary tank again by auxiliary tank, circulating pump, heater, expansion high-voltage tube, mould inside fluid passage;
(2), during cooling die, cold water does not operate at this cyclic process heater by by the path circulation that is linked in sequence like this of Returning water machine again of cooler, auxiliary tank, circulating pump, heater, expansion high-voltage tube, mould inside fluid passage;
One gas-phase space is formed at said auxiliary tank top, and has the exhaust passage.
Said system can be controlled automatically by controller, can be by being arranged at the temperature sensor of mould inside, its mold temperature data of measuring are input to controller, according to the temperature data of being imported, the unlatching of associated solenoid valve or close in the control system, thereby the circulation of control warm water, cold water or stop the circulation of water.
Compare with known technology (day disclosure special permission＜clear 63-128911 number 〉, United States Patent (USP) 4.902.454 number), the most important distinguishing characteristics of the present invention is to be provided with expansion high-pressure hose and auxiliary tank in the system.
Expansion high-pressure hose (can adopt the expanded rubber flexible pipe) then expands as pressurized, and water is flow in the mould with turbulent condition; The gas-phase space of forming by steam and air that the top of auxiliary tank forms, the effect of the bubble that forms in the separating pipe again when preventing to be subjected to back pressure from the water that mould flows into equally plays a part to improve water with rate of heat exchange between mould with the expansion high-pressure hose.
The shunt tributary pipeline of heater also can be set in the above-mentioned system architecture, cold water cyclic process when cooling die, water is by heater, and by by the path circulation that is linked in sequence like this of Returning water machine again of the shunt tributary pipeline of cooler, auxiliary tank, expansion high-pressure hose, heater, expansion high-voltage tube, mould inside fluid passage.Just, this moment, force (forcing) pump described later played a part circulating pump.Thus, when cooling die, a spot of water of staying in the heater can not flow into mould, thereby cooling die more promptly also improves the thermal efficiency of entire system.
Be provided with level sensor on auxiliary tank, level sensor preferably surrounds with the dividing plate of top formation tubbiness utensil.As there is not dividing plate just might mistake survey water level because of the water that flows into from mould.
Also have, increase on also can the path before auxiliary tank force (forcing) pump is set.As the pressure that improves auxiliary tank then not only can improve the temperature of recirculated water, also can suppress evaporation.

The specific embodiment
Below by Fig. 2 to Fig. 4 embodiments of the present invention are described in more detail.
Fig. 2 represents that 1 embodiment is respectively arranged by the circulating path of upper die and lower mould, and Fig. 3 represents the structure of auxiliary tank, and Fig. 4 represents what mold surface temperature was represented with the function of time.
Generally speaking, begin shaping work and must promptly start heater 14, with circulating pump 12B recirculated water mould and die preheating to proper temperature, water is along with auxiliary tank 13, circulating pump 12B, heater 14, expanded rubber pipe 15, mould 20 have been linked to be circulating path, with this heating mould 20.At this moment, close magnetic valve S1, S2, S3 and S4.Wherein, S2 and S4 can open and can close, but under the state of opening if start force (forcing) pump 12A, can improve the temperature of recirculated water, also can reduce evaporation capacity.Magnetic valve S5 and S6 are contained on the air discharge pipe of auxiliary tank, as the water level decline of auxiliary tank, then discharge the air and the steam of upper space.Mold temperature at the initial stage of empty mould cocycle warm water during warm-up phase rises as Fig. 4 straight line.
Mold temperature rises to management point (among Fig. 4 being 50 ℃) and just begins shaping work.Because molten moulding is injected into mould inner mould tool temperature and can rises, so cold water along with by cooler 11, auxiliary tank 13, circulating pump 12b, the heater 14 that does not operate, expansion high-voltage tube 15, mould 20, and the internal fluid passageway path circulation that is linked in sequence like this of Returning water machine 11 again, with cooling die.Cold water also can not pass through heater 14, is passed through by shunt tributary (path of representing with dotted line among Fig. 2), because the warm water of at this moment staying in the heater does not circulate, during heating mould, the thermal efficiency can be better.
Cold water can circulate continuously, but coldly also can circulate repeatedly and stop for preventing that mould from crossing, and also can circulate discontinuously.
Circulating water till carrying out repeatedly from the injection initial point to the goods off-take point, under the situation that begins till the injection initial point, to stop to circulate from the goods off-take point, the variation of mold temperature such as Fig. 4.
Said system is controlled automatically by controller 30, by being arranged on mould 20 temperature inside sensors 21, measure the temperature data of mould, with data input controller, controller is according to the temperature data of input, and the relevant magnetic valve on the control system water circulation path is controlled the circulation of warm water, cold water or stopped the circulation of water.
Below we regionally observe the temperature curve of Fig. 4 in more detail.
Begin recirculated cooling water when injecting, inject molten mould during (A interval) mold temperature sharply rise, end to be injected reduces (B-A interval) later on gradually.Mold temperature continues to drop to the circulation that stops cooling water when taking out products temperature (melting points of plastics) and takes out goods, takes out after the goods, owing to stayed the interior cooling water of mould pipeline and the influence of atmosphere, temperature sharply descends.As mentioned above, the circulation that at this moment stops cooling water is cold excessively for fear of mould.Again drop to the management point of 50 ℃ of mold temperatures as mold temperature, just begin new injection engineering, the production time of a process is represented with C.
When very high and peripheral temperature is quite low when the management point of mold temperature, occur even the cooling of obstructed supercooled water also has the cold excessively situation of mould, the temperature that the warm water that at this moment can circulate discontinuously compensation is fallen is managed mold temperature.Otherwise circulating water is managed temperature.
