Description
Technical field
The utility model relates to plastic injection technique field, particularly a kind of die heater heating, cooling device.
Background technology
As shown in Figure 1, the die heater that in prior art, Injection Industry generally uses is made up of the water tank, multiple (being generally 5) magnetic valve, moisturizing magnetic valve, check valve etc. of 1 band heating tube.Its operation principle is: when startup mold heated program: No. 1, magnetic valve, No. 3, magnetic valve, magnetic valve No. 5 closed electromagnetic valves, No. 2, magnetic valve, magnetic valve No. 4 magnetic valves are opened, in water tank, hot water gets back to water tank, mold heated by No. 4, magnetic valve, mould, No. 2, magnetic valve under the effect of pump.When startup mold cools down program: magnetic valve 2, magnetic valve No. 4 closed electromagnetic valves, No. 1, magnetic valve, No. 3, magnetic valve, magnetic valve No. 5 magnetic valves are opened, the cold water of water inlet is by No. 3, magnetic valve, mould, No. 1, magnetic valve, water return outlet, complete the cooling to mould, pump startup simultaneously, the water of water tank bottom returns water tank upper by pump, No. 5, magnetic valve, completes repeats itself heating, for mould heating is next time prepared.
In actual job, find that there is following defect:
(1) this die heater hot and cold water handoff functionality is that dependence 5 magnetic valves cooperations realize; Water tank water supplement function relies on other tongue tube liquid level gauge and 1 magnetic valve to realize.Magnetic valve is more, and equipment failure rate is higher.
(2) magnetic valve is harsh to the requirement of water quality, and the minute impurities in water can make closed electromagnetic valve not tight, causes hot and cold water mixing in pipeline, not obvious to the heating cooling effect of mould, affects product quality and output.
(3) water tank of this die heater is comparatively large, and water temperature heats up slow, affects production efficiency.
(4) in water tank, incrustation scale affects the sensitivity level of tongue tube water-level gauge, often occurs that water tank moisturizing burns out the phenomenon of heating tube not in time.
Utility model content
(1) technical problem to be solved
Technical problem to be solved in the utility model be to provide a kind of die heater heating, cooling device, with overcome die heater magnetic valve too much causing trouble rate in prior art higher, heating cooling effect not obvious, affect production effect and easily occur burning out the defect of heating tube.
(2) technology contents
In order to solve the problems of the technologies described above, the utility model provides the heating of a kind of die heater, cooling device, comprising: electric three passes ball valve, heating tube and flow inductor;
3rd end of described electric three passes ball valve is communicated with water return outlet, and the second end of described electric three passes ball valve is connected with heating tube, is communicated with after the first end connecting mold of described electric three passes ball valve with water inlet;
Described heating tube connects pump and in parallel with mould;
Described flow inductor controls the start-stop of described heating tube;
When starting mold heated program, first end and second end of described electric three passes ball valve are open-minded, pump startup, flow inductor switch connection, and start heating to heating tube, hot water is mold heated;
When starting mold cools down program, first end and the 3rd end of described electric three passes ball valve are open-minded, pump stall, and heating tube stops heating, and cold water through mould, through electric three passes ball valve, flows to water return outlet from water inlet.
(3) beneficial effect
The utility model provides the heating of a kind of die heater, cooling device, can reduce the fault rate of die heater; Improve die heater to the adaptability of common water quality, improve heating cooling effect; Change mode of heating, be rapidly heated; Available protecting heating tube, at utmost reduces maintenance cost, enhances productivity.
Accompanying drawing explanation
Fig. 1 is prior art structural representation;
Fig. 2 is the heating of the utility model die heater, cooling device structural representation.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used to limit scope of the present utility model.
As shown in Figure 2, the utility model provides the heating of a kind of die heater, cooling device, comprising: electric three passes ball valve, heating tube and flow inductor;
3rd end of described electric three passes ball valve is communicated with water return outlet, and the second end of described electric three passes ball valve is connected with heating tube, is communicated with after the first end connecting mold of described electric three passes ball valve with water inlet;
Described heating tube connects pump and in parallel with mould;
Described flow inductor controls the start-stop of described heating tube;
When starting mold heated program, first end and second end of described electric three passes ball valve are open-minded, pump startup, flow inductor switch connection, and start heating to heating tube, hot water is mold heated;
When starting mold cools down program, first end and the 3rd end of described electric three passes ball valve are open-minded, pump stall, and heating tube stops heating, and cold water through mould, through electric three passes ball valve, flows to water return outlet from water inlet.
The die heater heating that the utility model provides, cooling device tool have the following advantages:
(1) this die heater heating, cooling device utilize 1 electric three passes ball valve to carry out the function of alternative former die heater 5 magnetic valves, and fault rate reduces.(2) feature of electric three passes ball valve is that the closedown of valve body is opened and applied by electronic external force, and valve body is closed tight, can adapt to common water quality well, there will not be hot and cold water mixing phenomena in pipeline.Obvious to the heating cooling effect of mould, product quality and output significantly improve.(3) eliminate former die heater water tank, adopt mode of heating in pipeline, the quantity of circulating water that needs are heated reduces, and water temperature quick heating, production efficiency significantly improves.(4) eliminate former die heater tongue tube water-level gauge water compensation mechanism, install the work that flow switch controls heating tube additional, when having current to flow in pipeline, heating tube is started working, and do not have current, heating tube quits work, and protects heating tube well, reduces maintenance cost.
Embodiment
Within 2014, the present embodiment uses 8 in grand celebration the Kunlun Guan Ye branch company of group company, and contrast the old and new die heater service condition finds, use the mold temperature of new die heater to want high 6-8 DEG C, heating and cooling time decreased, production efficiency improves.In addition, new die heater adapts to ordinary tap water water quality, do not exist leak, spilling water, heating tube burnout phenomenon, fault rate significantly reduces.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
