Abstract
The invention relates to a heat-insulating shooting cylinder which comprises a sand storage cylinder and a shooting head body connected to the lower part of the sand storage cylinder, wherein a sand adding opening is formed in the upper part of the sand storage cylinder; a sand discharging opening is formed in the lower part of the sand storage cylinder and is communicated with the shooting head body; the sand storage cylinder comprises a metal outer layer arranged on the outmost layer of the stand storage cylinder and a metal ceramic inner layer arranged on the innermost layer of the sand storage cylinder; and a hollow sealing layer is arranged between the metal outer layer and the metal ceramic inner layer. According to the heat-insulating shooting cylinder disclosed by the invention, a hollow sealing cavity is used as an intermediate layer, so that the influence on the temperature of a sand core caused by outside conditions such as temperature is effectively reduced; and a metal ceramic composite material is used as the inner layer, so that the problem that sands are attached to the inner wall of the shooting cylinder is solved.
Description
Technical field
the present invention relates to penetrate the sand device, particularly relate to a kind of insulation and penetrate tube.
Background technology
to the preparation of core, are adopted usually and are penetrated the sand device in foundry production.Penetrate the sand device core sand is injected in the core box with high speed, form core sand through the consolidation moulding again.Penetrating sand mechanism generally comprises cartridge, penetrates a body and penetrates sand exhaust gear etc.Wherein, cartridge still owing to the variation of external temperature environment, directly can have influence on the Forming Quality and the speed of core sand in the cartridge as the term suggests be used to store core sand, also often occurs scab easily on the cartridge inwall simultaneously, causes the difficulty in the cleaning.
Summary of the invention
the purpose of this invention is to provide a kind of insulation and penetrate tube.
For achieving the above object, the technical scheme that the present invention adopts is:
Tube is penetrated in
a kind of insulation; Comprise cartridge, be connected the body of penetrating of described cartridge bottom; Described cartridge top offers and adds the sand mouth, and the bottom offers sand export, and described sand export is connected with a described body of penetrating; Described cartridge comprises the cermet internal layer that is arranged on outermost metal outer, is arranged on innermost layer, is provided with the hollow sealing layer between described metal outer, the cermet internal layer.
preferably, described metal outer is Q235A.
preferably, described cermet internal layer attaches the ceramic powders sintering for the seamless steel pipe inner chamber is coated with and forms.
preferably, the thickness of described cermet internal layer is 10-15mm.
Because the technique scheme utilization, the present invention compared with prior art has advantage:
1, adopts the hollow sealing chamber as the intermediate layer, effectively reduced the influence that the core sand temperature receives external conditions such as environment;
2, employing ceramic-metal composite solve an inwall scab problem of penetrating as internal layer.
Description of drawings
accompanying drawing 1 is a structural representation of the present invention.
wherein: 1, cartridge; 10, metal outer; 11, hollow sealing layer; 12, cermet internal layer; 13, add the sand mouth; 14, sand export; 2, penetrate a body.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Tube is penetrated in
a kind of insulation as shown in Figure 1, comprise cartridge 1, be connected cartridge 1 bottom penetrate a body 2, cartridge 1 top offers and adds sand mouth 13, the bottom offers sand export 14, sand export 14 with penetrate a body 2 and be connected.
in the present embodiment, cartridge 1 comprises the cermet internal layer 12 that is arranged on outermost metal outer 10, is arranged on innermost layer, is provided with hollow sealing layer 11 between metal outer 10, the cermet internal layer 12.Like this, outside metal outer 10 can give cartridge 1 with enough rigidity, satisfies the functional requirement of penetrating sand; The hollow sealing layer 11 at middle part plays effective isolation, has reduced ambient temperature and has changed the influence to inner core sand, plays insulation effect; 12 inner of cermet coatings can be avoided sticking of core sand, easy cleaning.
metal outer 10 general Q235A materials that adopt have good welding performance; Cermet internal layer 12 is seamless steel pipe (material 20 steel), and inner chamber processing back is gone up ceramic powders and sintered into, and thickness is generally the 10-15 millimeter.
the foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
Claims (4)
