Embodiment
As shown in Figure 1, present embodiments providing a kind of device 100 of measurement precoated sand shelling property, main measurement overlay film
Sand husking yield.
The device 100 for measuring precoated sand shelling property includes ontology 110.Ontology 110 includes heating mechanism 120.Heating mechanism
120 for precoated sand to be heating and curing.It should be noted that in the present embodiment, heating room 126 is connected with heating system.
Heating mechanism 120 includes main body 121, the first rotation axis 122 and the second rotation axis 123.Distinguish at the both ends of main body 121
It is connect with one end of the first rotation axis 122 and the second rotation axis 123.The other end of first rotation axis 122 and the second rotation axis 123
It is connect respectively with the two side walls of ontology 110.In other words, specifically, the first rotation axis 122 includes opposite first end and second
End.Second rotation axis 123 includes opposite third end and the 4th end.First end is connect with main body 121, second end and ontology 110
Side wall connection.Third end is connect with main body 121, and the 4th end is connect with the side wall of ontology 110.That is, being connected to 121 liang of main body
First rotation axis 122 and the second rotation axis 123 at end can drive main body 121 to rotate.
Secondly, the first rotation axis 122 is connect with driver 150, and in the present embodiment, driver 150 mainly selects motor.
Second rotation axis 123 is equipped with grafting axis 124 close to one end (i.e. third end) of main body 121.Main body 121 is equipped with interface.Grafting
Axis 124 coordinates with interface.That is, in the present embodiment, grafting axis 124 is inserted into interface, while 124 energy of grafting axis
It is enough to be rotated in interface.Grafting axis 124 can be understood as the columned body of rod.
The diameter of grafting axis 124 is less than the diameter of the second rotation axis 123.That is, the second rotation axis 123 itself and main body 121
Except connection, grafting axis 124 also coordinates with main body 121, and the second rotation axis 123 mainly drives main body 121 to rotate, grafting axis 124
The effect for primarily serving transmission rotation and supportive body 121 makes main body 121 rotationally more stablize.Therefore it is de- to measure precoated sand
The device 100 of shell can steadily be rotated when being heated to precoated sand, can be divided rapidly without cured loose sand
From keeping measurement result more accurate.
Further, main body 121 includes the first segment 121a being connected with each other and second segment 121b.It should be noted that
In the present embodiment, the shape of main body 121 is unlimited, it is preferable that main body 121 is cylindric.Wherein, first segment 121a and second segment
121b surrounds main body 121 jointly, that is, first segment 121a and second segment 121b are also cylindrical.First segment 121a be equipped with into
Material mouth 125, second segment 121b are equipped with heating room 126, and feeding mouth 125 is connected to heating room 126.Precoated sand can be from feeding mouth 125
Into, enter back into heating room 126 in heating.
In the preferable embodiment of the present embodiment, the width of feeding mouth 125 is less than the width of heating room 126.At this point, covering
Film sand uniformly and can be not easy unrestrainedly that feeding mouth 125 enters in heating room 126 smaller from width.Further, feeding mouth
125 are set to the middle part of first segment 121a.At this point, precoated sand equably can be dispersed to four to heating room 126 from feeding mouth 125
Week.Preferably, interface is set to first segment 121a.Since the width of feeding mouth 125 is less than the width of heating room 126, the
The remaining side wall volumes of one section of 121a are larger, and interface is set to first segment 121a, after grafting axis 124 coordinates with interface, energy
Entire main body 121 is driven steadily to rotate.Preferably, feeding mouth 125 is in funnel-form, and precoated sand can be preferably from feeding mouth 125
Pan feeding.
Ontology 110 further includes material receiving mechanism 130, and material receiving mechanism 130 is opposite with the discharge port of heating mechanism 120.That is, not
Cured precoated sand can be fallen on material receiving mechanism 130.Material receiving mechanism 130 includes pedestal 131 and receiver 132, receiver
132 are placed on pedestal 131.In other words, receiver 132 is placed on pedestal 131, can take out receiver 132 from pedestal 131
It separates out.Pedestal 131 and the bottom end interval of ontology 110 are arranged.That is, pedestal 131 do not have with the bottom end of ontology 110 it is certain away from
From.It is convenient for pulling out receiver 132 from pedestal 131 in this way.
The device 100 for measuring precoated sand shelling property further includes console 140, and ontology 110 is placed on console 140.Specifically
Ground, in the present embodiment, console 140 include heat button 141, heating instruction 142, start button 143, start instruction 144,
Power knob 145, power supply instruction 146, temp controlled meter 147, first timer 148 and second timer 149.
The present embodiment additionally provides a kind of system (not shown) of measurement precoated sand shelling property, including electronic scale and above-mentioned survey
Measure the device 100 of precoated sand shelling property.Electronic scale and measure precoated sand shelling property device 100 it is separately positioned, that is, electronic scale with
The device 100 for measuring precoated sand shelling property is not attached to together.
The operation principle of system for measuring precoated sand shelling property is：Under the conditions of simulating precoated sand core manufacturing craft, precoated sand exists
Under certain temperature, after a certain period of time by heat cure, uncured precoated sand can be layered, by cured and uncured sample sand
Weight percent, as shelling property.
Its application method is：
1) power switch of instrument is opened, heating room 126 starts to warm up.
2) temperature of heating room 126 is controlled by temp controlled meter 147, ranging from (160 DEG C~350) DEG C of setting are specific steady
Surely can be depending on the mold temperature of practical coremaking, or refer to the normal temperature (232 ± 5 DEG C) of national standard sample preparation.
3) it is to be denoted as M1, weight term of reference (300-600) ± 0.01g to take the weight of overlay film sand sample sand to be measured；
4) after heating room 126 reaches set temperature, heat preservation a period of time (5-10) mins, by precoated sand to be measured by entering
Material mouth 125 equably pours on heating room 126；Start test switch simultaneously, timer works, controlled by timer one at the beginning
The hardening time of sample preparation sand is usually set to (60-90) s.
5) first timer 148 controls rotary electric machine, and after the time arrives, driver 150 can drive heating room 126 to revolve clockwise
Turn certain angle (90-180) degree；It is connect in emery disc at this point, can be trickled down without cured loose sand；These loose sands are picked out rapidly,
It is denoted as M2 again.
6) maintain the position of heating room 126 constant, sample sand will continue to by heat cure, then loosely, the undesirable precoated sand of solidification,
Under the effect of gravity, it will split away off on connecing emery disc, the sand total weight to fall off is M3.
7) when the precoated sand on heating room 126 no longer falls off, then off-test；Second timer 149 is control heating
The time that the rotation of room 126 is restored, it is traditionally arranged to be (5-10) min.
8) calculation formula of husking yield Φ：
Φ=M3/ (M1-M2) × 100%
The system provided in this embodiment for measuring precoated sand shelling property can accurately detect the hulling performance of precoated sand, to straight
The reversed performance for answering phenolic resin produces selection resin model for precoated sand and performance criteria provides direct basis.Secondly, it measures
The device 100 of precoated sand shelling property is adjusted using intelligent temperature controller, it is ensured that the temperature of heating room 126 is stablized.Timing is convenient, operation
Simply, the repeatability and reproducibility of data is very good.
Above description is only a specific implementation of the present invention, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replace, it should be covered within the scope of the utility model.
