Abstract
The utility model discloses a kind of hydraulic castings studs, including cope, drag box, sand core and stud, the sand core is arranged on drag box, the stud includes the side plate and middle plate of the left and right sides, it is connected and is formed by intermediolateral column between the side plate and middle plate, the intermediolateral column is equipped with the extension extended to the outside of side plate, there is thread segment on the extension, one end of the stud is fixedly connected on cope to fix stud by the thread segment of extension, and other end side plate is bonded to withstand sand core and prevent sand core from floating with sand core.By the above-mentioned means, the utility model hydraulic castings stud, is capable of fixing stud, and prevent sand core from floating, structure is simple, securely and reliably.
Description
Technical field
The utility model relates to hydraulic casting fields, more particularly to a kind of hydraulic castings stud.
Background technique
Contain a lot of runners in hydraulic castings, the size of runner affects the flow velocity of hydraulic part.In casting, molding runners
Sand core often there is the case where runner deformation.Technique is sticked on sand core with common stud with glue at present.
This technique on sand core is sticked to glue with common stud and two kinds of problems often occurs: first is that glue can be poured in molten iron
Gas is generated when note, and casting is caused to have stomata generation；Second is that the mobile of sandbox can be dynamic when after moulding, it will lead to stud and fall.
The sand core of hydraulic part is generally relatively light, and the density of molten iron is higher than sand core, when molten iron enter casting type it is intracavitary after can make
It obtains sand core to float or deform, so needing to increase stud when necessary to prevent the behavior.General stud needs to put by viscose glue
It sets on sand core, but glue is also easy to produce gas, and easily falls.
Summary of the invention
The utility model is capable of fixing stud mainly solving the technical problems that provide a kind of hydraulic castings stud, and
And preventing sand core from floating, structure is simple, securely and reliably.
In order to solve the above technical problems, the technical solution that the utility model uses is: providing a kind of hydraulic castings use
Stud, including cope, drag box, sand core and stud, the sand core are arranged on drag box, and the stud includes the left and right sides
Side plate and middle plate, connected and formed by intermediolateral column between the side plate and middle plate, the intermediolateral column is equipped with to the outer of side plate
The extension that side extends, has thread segment on the extension, and one end of the stud connects by the way that the thread segment of extension is fixed
It connects to fix stud on cope, other end side plate is bonded to withstand sand core and prevent sand core from floating with sand core.
In one preferred embodiment of the utility model, the extension and intermediolateral column are integrally formed.
The beneficial effects of the utility model are: the utility model hydraulic castings stud, is capable of fixing stud, and prevent
Sand core floats, and structure is simple, securely and reliably.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings, in which:
Fig. 1 is the structural schematic diagram of one preferred embodiment of the utility model hydraulic castings stud；
The components in the drawings are labeled as follows: 1, cope, 2, drag box, 3, sand core, 4, stud, 41, side plate, 42, in
Plate, 43, intermediolateral column, 44, extension, 45, thread segment.
Specific embodiment
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model
Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
Referring to Fig. 1, a kind of hydraulic castings stud, including cope 1, drag box 2, sand core 3 and stud 4, sand core 3 are set
It sets on drag box 2, stud 4 includes the side plate 41 and middle plate 42 of the left and right sides, passes through intermediolateral column between side plate 41 and middle plate 42
43 connection compositions, intermediolateral column 43 are equipped with the extension 44 extended to the outside of side plate 41, have thread segment 45 on extension 44,
One end of stud 4 is fixedly connected on cope 1 to fix stud by the thread segment 45 of extension 44, other end side plate 41 with
The fitting of sand core 3 prevents sand core 3 from floating to withstand sand core 3.
In addition, extension 44 and intermediolateral column 43 are integrally formed.
It is different from the prior art, the utility model hydraulic castings stud is capable of fixing stud, and prevent on sand core
Floating, structure is simple, securely and reliably
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases
The technical field of pass, is also included in the patent protection scope of the utility model.
