Description
Technical field
The utility model relates to process structure used in a kind of filling sand technique, and in particular to a kind of T-type stud structure.
Background technique
This structure is suitable for Foundry Production, wherein the primary structure of use has sand core, and sand core is in Foundry Production for making
The material of moulding core is made of casting model powder, moulding sand binder etc.；Stud: in Foundry Production to prevent sand core from floating or tilting,
The support construction made using suitable material is melt into one with casting or machines away stud in processing；Originally use stud
Often the problem of stud indentation sand mold occurs, stud does not have due effect, some casting can not be by increasing stud quantity
Improve with size；It is to prevent stud from heading into the chaplet that sand mold is provided with ceramic, ceramic stud branch when originally using stud
Support often have displacement risk, while put stud prop up after stud cannot be positioned；The prior art there are: the upper and lower of stud is set
Chaplet is placed at the sand mold position of two sides, and chaplet is easy displacement, is needed to excavate again after chaplet displacement and be buried again
Enter chaplet or sand mold or sand core are scrapped into processing；It needs to judge placement location when placing stud, be detected with dedicated examination board etc.,
Stud also has displacement risk in casting process simultaneously, and stud cannot completely remove when shifting post-processing, causes product report
Useless risk.
Utility model content
Utility model aims to solve the sand mold positions that the above-mentioned prior art has the upper and lower two sides of setting stud
Chaplet is placed, chaplet is easy displacement, and chaplet needs to excavate embedment chaplet again again or will after shifting
Sand mold or sand core scrap processing；It needs to judge placement location when placing stud, be detected with dedicated examination board etc., while stud is being poured
Also there is the problem of displacement risk, stud cannot completely remove when shifting post-processing, cause scrap of the product risk in the process, mentions
It will not be shifted for a kind of stud, simplify operation；Improve the T-type stud structure of production efficiency.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of T-type stud structure, is suitable for using
The Casting Equipment of mold or core box, T-type stud structure include vertical core, cross bar portion and magnet part, and the core is in the shape of a rod,
The cross bar portion is located at the upper end of the core, and the cross bar portion and the core are integrated chemical conversion type, the lower end of the core
It is fixedly connected with the magnet part, the position that core is corresponded on the mold or core box to match with T-type stud structure offers admittedly
Determine hole, the bottom of the fixation hole is fixed with a connection magnet corresponding with magnet part in T-type stud structure, the fixation hole
Shape and the shape of the core match, the sky that enters for sand core is equipped between the mold or core box and the cross bar portion
Gap.The embodiment of the utility model is for the improvement that stud positioning is inaccurate in production, trouble is arranged and does；Original stud is transformed
At T-type stud, suitable hole is beaten needing to be arranged stud position, and bottom hole is arranged strong magnets, and when moulding is pre- in core box and external mold
A T-type stud is respectively put at position of boxing out, and is sucked on the magnet of bottom hole, T-type stud stays in sand core and sand mold after moulding, coremaking
It is interior；T-type stud accomplish it is sufficiently large, play the role of support sand core, do not use original chaplet, while will not shift；This
Design reduces the risk to form waste product, improves production efficiency.
Preferably, the core and the fixation hole are clearance fit.
Preferably, the bottom of the fixation hole offers the fixing groove for being used to accommodate connection magnet and magnet part,
The top surface of the fixing groove is abutted with the lower end surface of the core, and the length of the core is greater than the depth of the fixation hole.
Preferably, being arc-shaped transition between the cross bar portion and the core.
Preferably, the core section is rounded, the volume of the core is at least 2 times of cross bar portion volume.
The substantial effect of the utility model is: the design reduces the risk to form waste product, improves production efficiency.

Specific embodiment
Below by specific embodiment, and in conjunction with attached drawing, the technical solution of the utility model is made further specifically
It is bright.
Embodiment 1:
A kind of T-type stud structure (referring to attached drawing 1 and attached drawing 2), suitable for using the Casting Equipment of mold 4 or core box 7, makes
When on mold, mold is matched with sandbox 6, and in the top of mold, mold is in convex shape for sandbox configuration；Using on core box
When, core box is independent rectangular box, and T-type stud structure includes vertical core 2, cross bar portion 1 and magnet part 3, the core
In the shape of a rod, the cross bar portion is located at the upper end of the core, and the cross bar portion and the core are integrated chemical conversion type, the core
Lower end be fixedly connected with the magnet part, the position that core is corresponded on the mold or core box to match with T-type stud structure is opened
Equipped with fixation hole, the bottom of the fixation hole is fixed with a connection magnet corresponding with magnet part in T-type stud structure, described
The shape of the shape of fixation hole and the core matches, be equipped between the mold or core box and the cross bar portion for sand core 5 into
The gap entered.The core and the fixation hole are clearance fit.The bottom of the fixation hole offer one for accommodate company
The fixing groove of magnet and magnet part is connect, the top surface of the fixing groove is abutted with the lower end surface of the core, the length of the core
Greater than the depth of the fixation hole.It is arc-shaped transition between the cross bar portion and the core.The core section is rounded, institute
The volume for stating core is at least 2 times of cross bar portion volume.
Original stud is transformed into T-type stud by the present embodiment, plays suitable hole, bottom hole setting needing to be arranged stud position
Strong magnets respectively put a T-type stud in core box and external mold preformed hole position when moulding, suck on the magnet of bottom hole, moulding,
T-type stud stays in sand core and sand mold after coremaking；T-type stud accomplish it is sufficiently large, play the role of support sand core, do not use original
Chaplet, while will not shift；The design reduces the risk to form waste product, improves production efficiency.
Embodiment described above is a kind of preferable scheme of the utility model, is not made to the utility model any
Formal limitation, there are also other variations and modifications on the premise of not exceeding the technical scheme recorded in the claims.
