The specific embodiment
Below in conjunction with Figure of description, the present invention will be further described.
As shown in Fig. 1～6, dewax machine of the present invention comprises trough 1, movable frame 3, filter frame 4, heat(ing) coil 5, two convection current clamps 2, hydraulic piston.
Described trough 1 is rectangular structure, comprises four side plates and a base plate.Two convection current clamps 2 are arranged in trough, two convection current clamps 2 be arranged in parallel with the biside plate that described trough 1 is faced mutually respectively, on the side plate inwall parallel with described convection current clamp 2, be provided with some heat(ing) coils 5, that is to say, heat(ing) coil 5 is arranged between convection current clamp and side plate.Heat(ing) coil 5 and convection current clamp 2 are stainless steel.On described trough 1 interior plate, offer stream wax pan (not shown).Between two convection current clamps, movable frame 3 is set, is provided with filter frame 4 on movable frame, movable frame is connected with hydraulic piston.Movable frame moves under the driving of hydraulic piston, and moving direction is parallel with convection current clamp.
On convection current clamp 2, be provided with some pod apertures 21, the top edge of convection current clamp is b to the width of lower limb, and pod apertures is arranged on the top edge of the described convection current clamp of distance
place.Between the lower limb of described convection current clamp and trough base plate, be provided with spacing, spacing is
fig. 2 is mainly for showing structure and the installation site of convection current clamp 2 in trough 1 of convection current clamp 2.Each heat(ing) coil 5 is divided into the two-layer side plate inwall along trough 1 to be arranged, and be arranged in parallel with the base plate of trough 1.Fig. 3 is mainly for showing the structure of heat(ing) coil 5.
As can be seen from Figure 6, described movable frame 3 comprises the riser 31 and the flat board 32 that is connected riser 31 described in two that two Parallel Symmetrics arrange.Described filter frame 4 is arranged on the flat board 32 of described movable frame 3, between described two risers 31, is equipped with a shifting axle 7.On the top edge of the biside plate parallel with convection current clamp 2, be respectively provided with a slide rail 6, the both ends of described shifting axle 7 be arranged on two described on slide rail 6.
In trough 1 of the present invention, ammonium chloride solution is housed, ammonium chloride solution plays the effect of sclerosis formwork inwall, and heat(ing) coil 5 is interior to flow for the steam heating, for heating to ammonium chloride solution.The lower ammonium chloride solution of temperature in trough 1 flows into from the spacing 22 between convection current clamp lower limb and trough base plate, contact with heat(ing) coil 5, the temperature of ammonium chloride solution raises, ammonium chloride solution after temperature raises moves upward, then from the pod apertures 21 of convection current clamp 2, flow out, the convection type that falls flows.
The course of work of dewax machine of the present invention:
While starting working, movable frame 3 is positioned at one end of trough 1, formwork is transported on the filter frame 4 of movable frame 3, the shifting axle 7 on movable frame 3 slides along the slide rail 6 on trough 1 under the effect of hydraulic piston, thereby drives movable frame 3 from one end of trough 1, to move to the other end of trough 1.Because ammonium chloride solution temperature under the heating of heat(ing) coil 5 raises, can become wax liquid very soon by the wax-pattern fusing in formwork, the density of wax liquid, lower than the density of ammonium chloride solution, so wax liquid overflows in formwork, floats over ammonium chloride solution upper strata.Wax liquid is recycled in the container that holds wax liquid by the stream wax pan on trough 1.Formwork arrives after the other end of trough 1, is moved out of trough 1.The movable frame 3 that completes dewax work is moved back to original position under the effect of hydraulic piston.In trough 1 due to dewax machine of the present invention, be provided with some movable frames 3, so can treat that the formwork of dewax is placed on respectively in movable frame 3 by a plurality of, these formworks are transported to the other end of trough 1 successively by one end of trough 1, formwork dewax gradually in motion process, after dewax completes, formwork is shifted out to trough 1 in turn, can increase work efficiency greatly like this.
Due to formwork dewax, ammonium chloride solution is housed in formwork, the formwork that ammonium chloride solution is housed, through dewater unit, to be poured out ammonium chloride solution, the ammonium chloride solution after pouring out reclaims, and again imports in dewax machine.Recycle ammonium chloride solution, can be cost-saving, increase the benefit.
Dewax machine in prior art is chassis heating, and like this ammonium chloride solution of trough 1 bottom moves upward after being heated, and forms convection type and flows.In dewax process, wax-pattern fusing along with place, sprue gate, the grains of sand of trough bottom move upward under the drive of current, cause the grains of sand drop to formwork inside and be attached on formwork inwall, in the time of will causing like this formwork after dewax finishes to pour into a mould, formed product has flaw, and product percent of pass is low.And in trough 1 of the present invention, be provided with convection current clamp 2, between convection current clamp and side plate, be provided with heat(ing) coil, the interior ammonium chloride solution of trough is flowed in the mode of convection current, formwork is when dewax like this, the grains of sand at place, sprue gate just can not drop to formwork inside, but under the current of ammonium chloride solution drive, fall in the filter frame 4 on movable frame 3.So the qualification rate of utilizing dewax machine of the present invention to carry out the formwork product that forms when pouring into a mould after dewax improves.
Heat(ing) coil 5 of the present invention is sealed steam heating, and the water that steam condensation forms can not enter in trough 1, and the concentration of the ammonium chloride solution in trough 1 can not diminish like this, but keeps constant.If the water that steam condensation forms has entered trough 1, will make the concentration of ammonium chloride solution reduce, at this moment need to add ammonium chloride in ammonium chloride solution, make it recover original concentration, such words is waste water resource not only, and the consumption of ammonium chloride is also very large.So the present invention has not only saved the consumption that water resource has also reduced ammonium chloride.
The present embodiment is controlled movable frame by hydraulic piston and is moved around along slide rail; so the power set in the present embodiment are hydraulic piston; certainly power set should be not limited to hydraulic piston; Electrohydraulic push rod or electric pushrod also can be used as power set, as long as can provide the device of power all within protection scope of the present invention for moving around of movable frame.
The present invention is because the size of movable frame is certain, be that spacing between two risers of movable frame is certain, like this require the width of trough certain, but owing to being arranged on the difference of the number of the movable frame in trough, the length of trough can change according to the actual demand in production process.
Above; be only preferred embodiment of the present invention, but protection scope of the present invention is not limited to this, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim was defined.
