Abstract
The utility model discloses a sand core positioning structure, and relates to the field of sand molds. The sand core positioning structure solves the technical problem that due to the fact that in the prior art, a sand core is dislocated in the process of the mold assembling, products are scrapped. The sand core positioning structure comprises an upper box, a lower box and a sand core. The opposite faces of the upper box and the lower box are provided with cavities which can contain the sand core. The upper surface of the lower box is provided with a positioning groove which is located in the side wall of the cavity of the lower box, and a positioning protrusion corresponding to the positioning groove is arranged on the sand core. The sand core is limited inside a box body through the connecting method, and is fixed and prevented from moving in any direction. Therefore, the forming effect of a casting is guaranteed.
Description
[technical field]
The utility model relates to a kind of sand mo(u)ld, especially the sand core positioning structure in sand mo(u)ld.
[background technology]
Sand mo(u)ld is the casting technique commonly used for shape casting, need to put into core in special sand mo(u)ld for the production of ad hoc structure, but in sand mo(u)ld mould assembling process, top box can push away original seat to core, cause the core dislocation, and then causing casting forming rear flange face misrun, foundry goods does not reach technological requirement.
[summary of the invention]
The technical problem that the utility model solves is to provide a kind of sand core positioning structure, between external mold and core, increases keeper, effectively prevents the dislocation of mould assembling process core.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of sand core positioning structure, comprise top box, nowel and core, the opposite face of described top box and nowel is provided with die cavity, can hold described core in described die cavity, the upper surface of described nowel also is provided with locating slot and described locating slot is arranged on the sidewall of nowel die cavity, and described core is provided with the positioning convex of corresponding described locating slot.
Further, described core all arranges described positioning convex on adjacent two side, and some locating slots corresponding with positioning convex are set on described nowel.
Further, the lower surface of described top box is provided with the link slot corresponding with described positioning convex, and after top box and nowel mould assembling, positioning convex can partly be contained in link slot.
Further, described positioning convex is the inclined plane of matching with the sidewall of locating slot and link slot.
Further, the inclination angle on described inclined plane is 1 °～3 °.
The beneficial effects of the utility model:
Sand core positioning structure of the present utility model, be provided with location on core and external mold, location comprises the locating slot that is located on nowel and is arranged on the positioning convex on core, and positioning convex and position-limiting action after locating slot is connected, effectively prevent the phenomenon that causes foundry goods to be scrapped because of the core off normal.
These characteristics of the present utility model and advantage will be below the specific embodiment, accompanying drawing in detailed exposure.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the utility model is described further:
The top view that Fig. 1 is nowel in the utility model;
The upward view that Fig. 2 is core in the utility model;
Fig. 3 is positioning convex and the schematic diagram that coordinates of locating slot and link slot.
[specific embodiment]
The utility model provides a kind of sand core positioning structure, comprise top box, nowel and core, the opposite face of top box and nowel is provided with die cavity, can hold described core in die cavity, the upper surface of nowel also is provided with locating slot and locating slot is arranged on the sidewall of nowel die cavity, and core is provided with the positioning convex of corresponding locating slot.Core is placed in nowel when die cavity is interior, and positioning convex is absorbed in locating slot, and this connected mode forms spacing in casing to core, and fixedly core prevents core movement in any direction, thereby guarantees the molding effect of foundry goods.
Technical scheme below in conjunction with the accompanying drawing of the utility model embodiment to the utility model embodiment is explained and illustrated, but following embodiment is only preferred embodiment of the present utility model, not all.Embodiment based in embodiment, those skilled in the art are other embodiment that obtains under the prerequisite of not making creative work, all belongs to protection domain of the present utility model.
With reference to figure 1, Fig. 2 and Fig. 3, shown sand core positioning structure, comprise top box 2, nowel 1 and core 3, the opposite face of top box 2 and nowel 1 is provided with die cavity 5, can hold core 3 in die cavity 5, the upper surface of nowel 1 also is provided with on the sidewall that locating slot 41 and locating slot 41 be arranged in nowel 1 die cavity 5 and is communicated with die cavity 5, and core 3 is provided with the positioning convex 42 of corresponding locating slot 41.By the connection positioning action of locating slot 41 and positioning convex 42, the core in mould is fixed; Prevent that in the mould assembling process, top box promotes core, core departs from and causes the foundry goods of moulding can't meet processing request.Because the pre-sandbox of mould is special-purpose assorted equipment, therefore comparatively difficulty of locating slot is set on core, therefore select locating slot is located on casing.
Improved, can on the adjacent two side of core 3, positioning convex 42 all be set, some locating slots corresponding with positioning convex 42 41 are set on nowel 1, can to core, position at different directions, strengthen and play the position-limiting action to core.Positioning convex on core is selected different quantity and position according to the shape of core, columnar core for example, and positioning convex is arranged on the periphery of cylindrical shape core, and can be symmetrical arranged two.
With reference to figure 3, and be provided with the link slot corresponding with positioning convex 42 43 at the lower surface of top box 2, after top box 2 and nowel 1 mould assembling, positioning convex 42 can partly be contained in link slot 43.The link slot 43 that positioning convex point 42 is aimed at top box 2 can be assisted top box is formed to location, and the fiting effect of mould assembling is better, contributes to strengthen the effect of foundry goods moulding simultaneously.
In addition, one side sidewall of positioning convex shown in Fig. 3 42 and locating slot 41 and link slot 43 is the inclined plane of matching, be convenient to the installation of core 3 and the separation of casing, and the fit system that inclined plane is set quality of fit is required low, comparatively easy precise positioning core on mould.
Preferably, the inclination angle on inclined plane is between 1 ° to 3 °, be beneficial between core and casing lay and when transfering to, in core, the thickness of positioning convex 42 is guaranteed, and guarantees the intensity of core.
By above-described embodiment, the purpose of this utility model is by fully effective having reached.The personage who is familiar with this technology should be understood that the utility model includes but not limited to the content of describing in accompanying drawing and the top specific embodiment.Any modification that does not depart from function and structure principle of the present utility model all will be included in the scope of claims.
