Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
It should be noted that, when not conflicting, the embodiment in the present invention and the feature in embodiment can combine mutually.
Below with reference to accompanying drawing, concrete explaination is done to embodiments of the invention.
The reverse drainage system of a kind of die temperature controller of embodiments of the invention as shown in Figure 1, comprises mould 1, heater 2, pipeline, pumping 3 and discharge outlet 4.Pipeline comprises inlet pipe 5 and goes out pipe 6.The two ends of mould 1 respectively by inlet pipe 5, go out pipe 6 and be connected with the two ends of heater 2, mould 1, heater 2, pipeline form closed circuit.Pumping 3 is located on closed circuit, and discharge outlet 4 is communicated with closed circuit by pipeline, discharge outlet 4 is also provided with the first switch valve 7.
In embodiments of the invention, pumping provides power for closed circuit, and the closed circuit of die temperature controller arranges pumping, and can carry out draining easily by the reverse of pumping, structure is simple, draining is quick and convenient, and manufactures easy, and cost is low.
As shown in fig. 1, in an embodiment of the present invention, what pipeline was located in pumping 1 goes out pipe 6 place, certainly, also can be located at inlet pipe 5 place.Preferably also comprise cooler 8, that is located at pipeline goes out pipe 6 place, enters heater 2 after being cooled by the medium flowed out by mould again.Preferred cooler is direct cooler, also can be indirect cooler.
As shown in fig. 1, preferred direct cooler comprises cooling water inlet 9 and coolant outlet 10.Cooling water inlet 9 is communicated with the pipe 6 that goes out of pipeline by second switch valve 11, and coolant outlet 10 is communicated with the inlet pipe 5 of pipeline by the 3rd switch valve 12.And preferably discharge outlet 4 is communicated with the pipe 6 that goes out of pipeline by the first switch valve 7.And preferably discharge outlet 4 communicates with coolant outlet 10, is same outlet.
In addition, the circulatory mediator preferably in closed circuit is water, and the medium in cooler is non-water also.Closed circuit is also provided with thermometer, Pressure gauge, relief valve etc.Cooling water inlet place is also provided with pressure switch.First switch valve 7, second switch valve 11, the 3rd switch valve 12 are preferably magnetic valve.
As shown in fig. 1, the high-temperature water of returning from mould 1 gets back to die heater through going out pipe 6, after pumping 3 is pressurizeed, be transported to heater 2.Deliver to mould 1 after being heated by electrothermal tube, so circulate.In the process, when high-temperature water temperature is too high, system starts second switch valve 11, and cooling water enters system and directly cools high-temperature water, reduces the temperature of high-temperature water, thus realizes the object of constant temperature.
When the temperature of high-temperature water still maintains high temperature to design temperature, system starts high temperature alarm and quits work; When cooling water pressure does not reach setting requirement, pressure switch sends the signal of lack of water, and system starts low pressure alarming and quits work.When system needs to reverse emptying time, system closing second switch valve 11 and the 3rd switch valve 12, open the first switch valve 7, starts pumping 3 and reverse, the water inside system is discharged through the first switch valve 7 by pumping 3.
As shown in fig. 1, the reverse water discharge method of a kind of die temperature controller of the embodiment of the present invention, comprises the steps:
Step 1, by circulatory mediator, preferred oil or water, be placed in the reverse drainage system of die temperature controller.Pumping 3 runs well, and the first switch valve 7 cuts out, and circulatory mediator circulates in the closed circuit of mould 1, heater 2, pipeline formation;
Step 2, when needs reverse emptying, the first switch valve 7 is opened, and pumping 3 reverses, and circulatory mediator is discharged by discharge outlet through the first switch valve 7 by pumping 3.
As shown in Figure 2, in an embodiment of the present invention, the high-temp liquid of returning from mould 1 by arriving heater 2 after cooler 8, after being heated by electrothermal tube through pumping 3 pressurized delivered to mould 1, so circulate.In the process, be also provided with at the liquid-level switch of heater 2 and moisturizing magnetic valve, after liquid level drops to setting value in heater 2, open moisturizing magnetic valve, replenishment system water, ensure system normal operation (when using water to mediate).If temperature of high-temp liquid is too high, system starts second switch valve 11, and cooling water enters system and indirectly cools high-temp liquid, reduces the temperature of high-temp liquid, thus realizes the object of constant temperature.If the temperature of high-temp liquid still maintains high temperature to design temperature, system starts high temperature alarm and quits work.
As shown in Figure 3, in an embodiment of the present invention, preferred cooler 8 is built in heater 2 and indirectly cools high-temp liquid, reduces the temperature of high-temp liquid, thus realizes the object of constant temperature.
As shown in Figure 4, in an embodiment of the present invention, preferred cycle loop is also provided with safety valve 13, when system pressure is too high, safety valve 13 is opened and is carried out pressure release to system, provides security of system.
As shown in Figure 5, in an embodiment of the present invention, circulatory mediator is oil, is also provided with fuel tank 14 with replenishment cycles medium.The high temperature oil of returning from mould 1 flows to cooler 8 through back of pipeline, is then transported to heater 2 by pumping 3 and heats through electrothermal tube, then through to mould 1, so circulate.In this process, if high temperature oil temperature is too high, system starts second switch valve 11, and cooling water flows into cooler 8 pairs of high temperature oil and indirectly cools, and reduces high temperature oil temperature, thus realizes the object of constant temperature; If the temperature of high temperature oil still maintains high temperature to design temperature, system starts high temperature alarm and quits work; Be arranged on the liquid-level switch of fuel tank 14 li, when liquid level drops to certain position, send low liquid level signal, system starts low liquid level warning.
Be described in detail specific embodiments of the invention above, but it is just as example, the present invention is not restricted to specific embodiment described above.To those skilled in the art, any equivalent modifications that the present invention is carried out and substituting also all among category of the present invention.Therefore, equalization conversion done without departing from the spirit and scope of the invention and amendment, all should contain within the scope of the invention.
