Description
Technical field
The utility model is related to a kind of auxiliary mould, more particularly to a kind of flow coat jig belongs to casting die technical field.
Background technology
Cast paint can be such that molten metal is isolated with casting mold or whose surfaces, inhibit the chemical reaction between them,
Reduce or eliminate the chemical scab of cast(ing) surface；Cast paint can slow down casting mold or the radiation of core is heated, so as to reduce or disappear
Except the generation of burning into sand defect.Have the coating of certain cementitiousness, can also penetrate between casting mold and core surface layer sand grains, so as to
Strengthen the surface strength and erosion resistibility of casting mold or core, reduce the sand washing defect of casting.It is adiabatic by being added in coating
Material and chill material play the role of improving casting mold inner cavity Temperature Distribution with controlling alloy graining and crystallization process, so as to subtract
Few cast(ing) surface cold cracking and the generation of hot tearing.Add certain inovulants in coating or alloying element can also play part breed or
Surface alloying has the function that improve casting metallographic structure performance.
At present, the application of coating is main by the way of dip-coating, and entire sand core is immersed in dipping unit and is dragged for after a period of time
Go out.But the method can be applied on the non-casting face of sand core and be coated, and not only resulted in the waste of coating, can also be caused
The phenomenon that sand core molding is not tight, generation waste product.
Utility model content
The utility model is applied to coating to solve the non-casting face of sand core in the prior art and causes paint waste, sand core
The problem of molding is not tight, provides a kind of flow coat jig.
In order to achieve the above objectives, the technical solution of the utility model is as follows：
Flow coat jig includes the spray pipe of stent, jig plate, seal box and several different heights, the jig plate installation
In the top of the stent, the seal box is mounted on the lower section of the stent；It is placed for installing at the top of the jig plate
The gauge finder of sand core；There are one non-return valve, top has one and is connect with external air pump for the bottom setting of the seal box
Air inlet pipe；The spray pipe is vertically mounted in the gauge finder, if being provided on the pipe shaft at the spraying end of the spray pipe
Dry spraying hole, connecting pin is connect by applying expects pipe with the liquid outlet of the seal box.
Further, the liquid outlet of the seal box is located at the lower semisection of boxboard.
Further, corresponding to installation at the non-return valve in the seal box, there are one isolation covers.
Further, inspection hole is provided at the top of the seal box and is covered in transparent in the inspection hole
Sealing cover.
Further, the both ends of the stent have the hanger hung on coating pool side.
The operation principle of above-mentioned painting stream jig is：Seal box is placed in coating pond, coating open non-return valve, coating from
The bottom of seal box enters in seal box, and after the coating in case to be sealed is full of, non-return valve is closed under the effect of gravity.Work
When making, first it is passed through compressed air into seal box, the coating in seal box enters coating under compressed air effect from liquid outlet
Pipe and spray pipe, coating is from the nozzle and spraying hole jet flow to the sand mold for treating flow coat of spray pipe, so as to complete a flow coat mistake
Journey.In above process, the coating that spray pipe sprays is applied directly on the casting face of sand core, is not contacted with non-casting face.
As described above, the beneficial effects of the utility model are：1. applying the use of stream jig can not only prevent coating from applying
Onto the non-casting face of sand core, and flow coat process can also be made to obtain larger improvement, and improve the efficiency of flow coat；2. spray pipe
Several spraying holes on pipe shaft can improve the coating quality of sand core by coating homogenous application on the casting face of sand core；3.
The size of seal box is customized according to the coating aequum of sand core, and the dope layer that can prevent sand core casting face is blocked up.
