Description
Technical field
The utility model relates to a kind of sand core positioning tools, and in particular to a kind of more case sand core positioning tools belong to casting
With equipment Technology field.
Background technique
Sand casting refers to the casting method that casting is produced in sand mold.Steel, iron and most of non-ferrous alloy castings all may be used
It is obtained with sand mould casting method.The Modeling Material as used in sand casting is cheap and easy to get, and Casting mold manufacturing is easy, to the list of casting
Part production is produced by batch and is adapted to mass production, is always the basic technology in Foundry Production for a long time.Sand mold casting
It makes and middle needs that molding box and matched type core (being also sand core) is used to carry out molding product as mold.
The product quality that monotype case die casting goes out is not uniform enough, and product is difficult to intact taking-up from molding box, because
Monotype case mold can be divided into more box structures according to the structure of cast member by this, be also convenient for finished product while improving final product quality
It takes out.Currently, common more casees are cast into three casees castings, molding box is made of top case, cheek and drag box, this structure
Molding box is in casting process, and the sand core positioning of top case, cheek and drag box is more difficult, especially top case and mo(u)ld bottom half
It misplaces between case serious, it is difficult to the correct position of easy positioning sand core.Existing frequently-used localization method is in cheek sand core
Mud is put on drag box sand core or top case sand core, then by drag box or top case and cheek mould assembling, utilizes drag box
Or top case again unpacks mud compacting with cheek sand core, measures mud thickness and mud thickness and product design wall thickness are done ratio
Compared with if mud thickness proves sand core accurate positioning in the margin of tolerance, if mud thickness needs weight beyond design size
New adjustment sand core position.The localization method needs repeated measurement size, and the numerical value of operator's difference measurement is different, cause error compared with
Greatly, and its inefficiency；Furthermore sand core is easy mobile dislocation in casting process, and it is more that the product cast out is easy to appear side
Phenomena such as meat, other side misrun, wall unevenness, qualification rate is lower.
Utility model content
In order to overcome defect existing in the prior art, the purpose of this utility model is to provide a kind of structures simply, sets
It counts ingenious, positioning simple accurately more case sand core positioning tools, the tooling accurately to be positioned top case and drag box, energy
Effectively prevent top case and drag box from relatively moving the deficiency for causing sand core location difficulty, the tooling by compensation increase hole and
Compensation height stick can simply and easily judge whether the positioning of cheek sand core is accurate.
To achieve the goals above, the utility model uses a kind of following technical scheme: more case sand core positioning tools, including
The left and right sides is respectively arranged with the upper box and lower box of mutual corresponding mounting ear, passes through between the upper box and lower box
Locating shaft and fastener in mounting ear are flexibly connected；The upper box lower part and the top of lower box are respectively set
There is compensation to increase hole, which, which increases, is provided with compensation height stick in hole.
The upper box is respectively arranged with corresponding mounting ear with the front and rear sides of lower box, and it is fixed to be provided in mounting ear
Position axis, locating shaft are flexibly connected by fastener.
Contour structures of the interior shape structure of the upper box and lower box respectively with top case and drag box match.
The number that hole is increased in the compensation on the upper box lower part and lower box top at least has 3 respectively.
Compared with prior art, the utility model due to using the technology described above, has the advantages that this
Utility model structure is simple, ingenious in design, can carry out top case and drag box while accurately limit is fixed namely
Top case sand core and drag box sand core are accurately positioned, effectively prevents top case and drag box from relatively moving and causes mo(u)ld top half
The deficiency of case sand core and drag box sand core location difficulty；The tooling increases hole by compensation and compensation height stick can simple, side
Whether the sand core positioning for judging cheek just is accurate, to improve casting efficiency instead of traditional artificial multiple measurement
While measurement error also greatly reduces.In short, the tooling simply and easily can carry out essence to sand core in casting process
True positioning can effectively prevent sandbox and sand core from misplacing, scarce so as to avoid the product side fleshiness, the other side cast out
Phenomena such as meat, wall unevenness, casts efficiency and qualification rate is all greatly improved.
Detailed description of the invention
Fig. 1 is the main view of the utility model；
Fig. 2 is the utility model lower box top view；
Fig. 3 is the A-A structural schematic diagram of Fig. 2；
In figure: upper box 1, compensation increase hole 2, compensation height stick 3, locating shaft 4, fastener 5, mounting ear 6, lower box 7.
Specific embodiment
The utility model is further described in the following with reference to the drawings and specific embodiments:
It is as shown in FIG. 1 to 3: a kind of more case sand core positioning tools, including the left and right sides be respectively arranged with it is mutual corresponding
The upper box 1 and lower box 7 of mounting ear 6, the locating shaft 4 between the upper box 1 and lower box 7 by being located in mounting ear 6
And fastener 5 is flexibly connected；1 lower part of upper box and the top of lower box 7 are respectively arranged with compensation and increase hole 2, should
Compensation, which is increased, is provided with compensation height stick 3 in hole.
The upper box 1 is respectively arranged with corresponding mounting ear 6, setting in mounting ear 6 with the front and rear sides of lower box 7
There is locating shaft 4, locating shaft 4 is flexibly connected by fastener 5.
Contour structures of the interior shape structure of the upper box 1 and lower box 7 respectively with top case and drag box match.
The number that hole 2 is increased in the compensation on 1 lower part of upper box and 7 top of lower box at least has 3 respectively.
