Abstract
The utility model provides a compound seal structure of core shooting machine core box, the core box comprises with lower core box upper core box be provided with the seal groove on upper core box or the lower core box be provided with the sealing strip in the seal groove the bottom is provided with sealed glue in the seal groove, sealed glue is closely adhere with seal groove and sealing strip respectively, sealed glue corresponds the compound seal structure of complex with common constitution of sealing strip and seal groove. The utility model discloses a sealed glue or the structure sealing that pour into earlier the high elasticity in the seal groove into glue the back, the sealing strip is gone into to the reload, can reduce the magnitude of interference between sealing strip and seal groove like this, even both can be for the running fit, owing to sealed glue is closely adhere with seal groove and sealing strip behind the compound die, the sealing strip is little with the seal groove magnitude of interference, and the sealed elasticity of gluing is big, consequently, can solve the high protruding problem in sealing strip extrusion back, the life of sealing strip has been prolonged, the sealing performance of core box has been guaranteed, the useless of in production core has been reduced, the substandard product.
Description
Technical field
This utility model belongs to core shooter technical field, particularly to the core shooter core box compound sealing structure in a kind of casting industry.
Background technology
Core shooter coremaking is the major technique of modern coremaking, as shown in Figure 1, its coremaking principle is after applying compression air by the molding sand 6 in correlation sand frame 5, molding sand rushes in core box with compression air one shooting, so that the molding sand in core box has certain degree of packing, subsequently the molding sand in core box is blown and harden, namely form fuse.Require penetrating sand frame, wanting good seal between air blowing frame and core box and between each parts of core box of equipment penetrating sand and air blowing process, if leakage to produce to run sand, deflation, have a strong impact on the fuse degree of packing, intensity and production environment.
What existing core box adopted is sealed into rubber weather strip sealing, as shown in Figure 2, sealing strip 3 exceeds sealing surface certain altitude after loading seal groove 2, by the sealing strip indentation sealing groove that exceeds after sealing surface matched moulds, as long as the pressure amount of sealing strip can reach sealing effectiveness more than the flatness of sealing surface.Cooperation between seal groove requires interference fit, and otherwise sealing strip to come off, to blow away.The magnitude of interference of seal groove and sealing ring and sealing ring material, structure, making precision, ambient temperature have close relation, are difficult to make interference reach perfect condition in actually used.The bigger magnitude of interference is often selected in order to prevent sealing strip from coming off in actually used, and the bigger magnitude of interference not only makes sealing strip installation difficulty, and not only transversely deforming is big after sealing strip is extruded, also to produce bigger linear deformation simultaneously, bigger linear deformation can make sealing strip local high convex after release, high protuberance position repeatedly extrude after frangibility or eject seal groove, cause sealing strip short for service life, if sealing strip in use damages, then the fuse in production can be made to produce useless, substandard products.
Utility model content
Goal of the invention of the present utility model is in that: for above-mentioned Problems existing, it is provided that a kind of service life that can improve sealing strip, reduces the core shooter core box compound sealing structure of useless, the substandard products of fuse in producing simultaneously.
The technical scheme of this utility model technology is achieved in that a kind of core shooter core box compound sealing structure, described core box is made up of upper core box and lower core box, core box or lower core box are provided with seal groove on described, it is provided with sealing strip in described seal groove, it is characterized in that: described seal groove inner bottom part is provided with fluid sealant, described fluid sealant collectively forms and the compound sealing structure of seal groove corresponding matching with seal groove and sealing strip close adhesion, described fluid sealant and sealing strip respectively.
Core shooter core box compound sealing structure described in the utility model, the thickness of its described fluid sealant is lower than the 1/5 of seal groove height.
Core shooter core box compound sealing structure described in the utility model, it is provided with in the seal groove of fluid sealant and during non-matched moulds when described sealing strip is placed in, and described sealing strip and seal groove side total backlash are not more than 0.5mm.
This utility model by after first injecting elastomeric fluid sealant or structure sealant in seal groove, reinstall sealing strip, so can reduce the magnitude of interference between sealing strip and seal groove, even both can be loose fit, due to fluid sealant and seal groove and sealing strip close adhesion after matched moulds, sealing strip is little with the seal groove magnitude of interference, and fluid sealant is elastic big, therefore high convex problem after sealing strip extrudes can be solved, extend the service life of sealing strip, ensure that the sealing property of core box, decrease useless, the substandard products of fuse in production.

Fig. 3 is structural representation of the present utility model.
Accompanying drawing labelling in figure: 1a is upper core box, and 1b is lower core box, and 2 is seal groove, and 3 is sealing strip, and 4 is fluid sealant, and 5 for penetrating sand frame, and 6 is molding sand.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
As shown in Figure 3, a kind of core shooter core box compound sealing structure, described core box is made up of upper core box 1a and lower core box 1b, core box 1a or lower core box 1b is provided with seal groove 2 on described, it is provided with sealing strip 3 in described seal groove 2, described seal groove 2 inner bottom part is provided with elastomeric fluid sealant 4, described fluid sealant 4 respectively with seal groove 2 and sealing strip 3 close adhesion, the blast when intensity of fluid sealant is more than cleaning sealing strip, described fluid sealant 4 collectively forms and the compound sealing structure of seal groove 2 corresponding matching with sealing strip 3.As such, it is possible to the magnitude of interference reduced between sealing strip and seal groove, even both can be loose fit, easy for installation, sealing strip linear deformation is little, decreases the total deformation of sealing strip, thus improve the service life of sealing strip, decrease useless, the substandard products of fuse in production.
Wherein, the thickness of described fluid sealant 4 is lower than the 1/5 of seal groove 2 height, and occurrence is according to sealing strip pressure amount, and fluid sealant intensity is determined；It is provided with in the seal groove 2 of fluid sealant 4 and during non-matched moulds when described sealing strip 3 is placed in, if sealing strip and seal groove are loose fit, described sealing strip 3 is not more than 0.5mm with seal groove 2 side total backlash, and after loading sealing strip, on probation one can quantitative, sizing after secondary.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within protection domain of the present utility model.
