Abstract
The utility model relates to a threaded hole structure of a directly-cast casting. The threaded hole structure comprises a casting. A threaded hole structure is arranged in the casting, and threads of the threaded hole are in spiral matching with threads of a bolt. By means of the casting threaded hole, graphite of a same type prearranged in a sand mold or sand core during molding is used for producing a bolt, and the bolt is screwed out after the casting is poured to form a threaded hole to achieve the threaded hole structure of the directly-cast casting structure. The threaded hole structure of the directly-cast casting can be used for threaded holes with not high requirements on castings, and has ideal practical effects.
Description
Technical field
The utility model relates to metallurgical casting, particularly a kind of thread pore structure of direct casting.
Background technology
At present in the Foundry Production, ask for something is not very high screwed hole because the coremaking difficulty is often produced upper being difficult for and made on the foundry goods, and adopts the mode of later stage machining.
How to improve this situation, and require its economy and validity, become the problem that these those skilled in the art need to solve.
Summary of the invention
Task of the present utility model provides a kind of thread pore structure of direct casting, it has solved the existing problem of above-mentioned prior art, preset same model graphite-made bolt when utilizing moulding in sand mold or the core, screwed hole after finishing, casting pouring is set, to realize the screwed hole structure in the casting structure.
Technical solution of the present utility model is as follows:
A kind of thread pore structure of direct casting, it comprises foundry goods, in the described foundry goods thread pore structure is set, the screw thread of this screwed hole cooperates with the bolt thread spiral.
Described thread pore structure is arranged on the position of foundry goods ecto-entad.
Preset same model graphite-made bolt when foundry goods screwed hole of the present utility model utilizes moulding in sand mold or the core, the bolt of back-outing after casting pouring is finished forms screwed hole, to realize the screwed hole structure in the direct casting structure.
It is not very high screwed hole that the thread pore structure of direct casting of the present utility model can be used for requiring on the foundry goods, has comparatively desirable practical function.
Description of drawings
Fig. 1 is the schematic diagram that presets the graphite-made bolt in sand mold or core.
Fig. 2 is the schematic diagram of the thread pore structure of a kind of direct casting of the present utility model.
Reference numeral:
1 is foundry goods, and 2 is sand mold or core, and 3 is the graphite-made bolt, and 4 is thread pore structure.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
Referring to Fig. 1 and Fig. 2, the utility model provides a kind of thread pore structure of direct casting, and it comprises foundry goods 1, and thread pore structure 4 is set in foundry goods 1, and the screw thread of this screwed hole 4 cooperates with the bolt thread spiral.
As shown in Figure 2, thread pore structure 4 is arranged on the position of foundry goods 1 ecto-entad.
Specifically constituting of direct casting thread pore structure of the present utility model: by presetting same model graphite-made bolt 3 in sand mold or the core 2, the bolt of back-outing behind foundry goods 1 casting complete forms thread pore structure 4.
In sum, preset same model graphite-made bolt when the thread pore structure of direct casting of the present utility model utilizes moulding in sand mold or the core, screwed hole is set after casting pouring is finished, to realize the screwed hole structure in the casting structure.
Certainly, those skilled in the art in the art will be appreciated that, above-described embodiment only is that the utility model is described, and be not with opposing restriction of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim the variation of above-described embodiment, modification etc.
Claims (2)
