Abstract
The invention belongs to the technical field of accessories of molding sand molding machine, and provides a core shooter sand shooting device provided with double air inlet pipes. The core shooter sand shooting device comprises an intermittent sand feeding mechanism, a sand shooting barrel, an inner sleeve and a sand shooting hopper, wherein the inner sleeve is located in the sand shooting barrel, an annular air channel is formed between the inner sleeve and the sand shooting barrel, the upper end and the lower end of the inner sleeve are connected with the intermittent sand feeding mechanism and the sand shooting hopper respectively, a plurality of airflow holes are formed in the wall of the inner sleeve, and at least one pair of air inlet pipes opposite at an air inlet of the annular air channel is arranged on the sand shooting barrel. According to the sand shooting device, molding sand can be uniformly carried by compressed air.
Description
Technical field
The invention belongs to the attachment technique field of sand molding machine.
Background technology
In modern foundry production, in order to improve the efficiency of casting, meet the requirement of modern production, the core used in casting process uses hot box shoot core machine manufacture mostly, core shooter is widely used in foundry machinery industry, with the core of hot box shoot core machine manufacture, there is size accurate, the advantages such as any surface finish, be therefore obtained application widely at a lot of foundry enterprise.
The most important structure of core shooter penetrates sand device exactly, it is generally made up of blasting unit, the inlet duct penetrated sand hopper and be connected with blasting unit upper end air inlet that is connected with blasting unit lower end, the inner sleeve storing molding sand is installed in blasting unit inner chamber, between inner sleeve and blasting unit, forms the gas flow of annular.Inner sleeve with penetrate sand hopper and communicate and inner sleeve wall have some airflow holes, while opening bottom inner sleeve, blasting unit passes into Compressed Gas, and Compressed Gas pours inner sleeve from airflow hole, sweeps along the molding sand in inner sleeve to enter and penetrates sand hopper, then penetrate in nozzle.
The shortcoming of technique scheme is: existing blasting unit only arranges single air inlet usually, when compressed air pours inner sleeve from the airflow hole near air inlet, its impulsive force is larger, can molding sand be blown on inner sleeve inwall, and the Compressed Gas of inner sleeve is poured from the airflow hole away from air inlet, its impulsive force is less, both effect superpositions are exactly that molding sand is blown to specific region in inner sleeve, cause it penetrating in sand hopper and can not be uniformly distributed, and nozzle is distributed on and penetrates bottom sand hopper, final result is exactly that different nozzle molding sand sand amount is out different with speed, product (core) quality cannot be guaranteed.
Summary of the invention
The invention is intended to provide a kind of and ensure that compressed air can sweep along the two air inlet pipe sand shot device of the core shooter of molding sand equably.
Object of the present invention can be reached by following measures: the two air inlet pipe sand shot device of core shooter, comprise interval Jin Sha mechanism, blasting unit, inner sleeve and penetrate sand hopper, it is characterized in that: inner sleeve blasting unit inner and and form annular air channel between blasting unit, the upper and lower side of inner sleeve is connected with interval Jin Sha mechanism respectively, penetrate sand hopper connects, the barrel of inner sleeve has some airflow holes, described blasting unit is at least arranged a pair air inlet pipe relative in the enterprising air port of annular air channel.
Technique scheme difference with the prior art is: the molding sand of regulation component can be sent into inner sleeve and penetrate in sand hopper by interval Jin Sha mechanism, the compressed air entered from air inlet pipe then enters inner sleeve through annular air channel-airflow hole, by in inner sleeve or the molding sand penetrated in sand hopper mix and sweep along and go out from the nozzle penetrating sand hopper, the improvement of this programme is, enterprising for blasting unit tracheae is arranged to air inlet relative, because air inlet is relative, Compressed Gas can liquidate and offset most of lateral impact forces in annular air channel, compressed air sweeps along molding sand enter inner sleeve in airflow hole after equably, avoid molding sand and be blown to certain specific region, molding sand is penetrated from nozzle equably.
Further, the cylindrical shell of described blasting unit is divided into internal layer and skin, is provided with heat-insulation layer between inside and outside layer, ensures that the temperature in blasting unit maintains certain level, avoids too high or too low temperature to cause molding sand consolidation.
Further, described airflow hole, higher or lower than the horizontal level of air inlet, prevents at airflow hole place air-flow too disorderly, and the molding sand in inner sleeve is taken out of.
Further, described blasting unit is provided with two to the air inlet pipe relative in the enterprising air port of annular air channel, makes compressed air more can sweep along molding sand equably.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the two air inlet pipe sand shot device embodiment of core shooter of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
The Reference numeral of Figure of description 1 comprises: 1-bearing support; 2-blasting unit; 3-penetrates sand hopper; 4-nozzle; 5-interval Jin Sha mechanism; 6-inner sleeve; 7-airflow hole; 8-air inlet pipe; 9-annular air channel.
Participate in accompanying drawing 1, the two air inlet pipe sand shot device of core shooter, comprise a bearing support 1, this bearing support 1 is fixed with cylindric blasting unit 2 by screw, and this blasting unit 2 is divided into internal layer and skin, and internal layer and outer field clearance layer are air heat insulating layer.The lower end of this blasting unit 2 is connected by ring flange with the sand hopper 3 of penetrating of a back taper, and this penetrates sand hopper 3 is also adopt double-decker, and with air heat insulating layer between ectonexine, the bottom surface penetrating sand hopper 3 is evenly distributed with some nozzles 4, and the loophole of nozzle 4 is vertical down.The upper end of blasting unit 2 is assembled into one with interval Jin Sha mechanism 5, is provided with the butterfly valve controlled into sand amount between this interval Jin Sha mechanism 5 and blasting unit 2 upper end open.Blasting unit 2 inner lower, with the erecting bed of projection, this erecting bed is placed with inner sleeve 6, and outer wall and blasting unit 2 inwall of inner sleeve 6 fit tightly, and the barrel top of this inner sleeve 6 has the airflow hole 7 of some circles.
Blasting unit 2 is threaded with two air inlet pipe 8, each air inlet pipe 8 comprises the vertical air inlet section being positioned at blasting unit 2 outside, and laterally run through the horizontal air inlet section of blasting unit 2, the horizontal air inlet section outer wall of this air inlet pipe 8 is also tightly connected with blasting unit 2, the annular groove that blasting unit 2 internal layer has in the junction with air inlet pipe 8, makes to form annular air channel 9 between the blasting unit 2 of this junction and inner sleeve 6.The horizontal air inlet section position of two air inlet pipe 8 is higher or lower than inner sleeve 6 airflow hole 7 position, and this airflow hole 7 communicates with annular air channel 9.The air inlet level that the horizontal air inlet section of two air inlet pipe 8 leads to annular air channel 9 is relative.
above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
