Abstract
The invention discloses a base of a core box made by a large diameter ductile iron pipe. The core box comprises a core box base, half dies and a core bar. The half dies, a base plate and the core bar form a cavity of a sand core, a big flat plate of the base is arranged on the core box base, a rib plate of the base is arranged on the lower surface of the big flat plate of the base, a reinforced rib plate of the base is arranged on the upper surface of the big flat plate of the base, and the rib plate of the base and the reinforced rib plate of the base are screwed or welded to the big flat plate of the base. The adoption of the technical scheme avoids the processing structure of the big flat plate and reduces the processing difficulty of the core box. Besides, one steel plate layer is additionally welded in the contact region on the basis of the original base plate, so that the strength of the base plate is enhanced, and the buckling deformation possibility is reduced. The adoption ofthe technical scheme also improves die design flexibility and lays excellent foundation for better producing more qualified sand cores and improving the qualified rate of pipe finished products.

The specific embodiment
Contrast accompanying drawing below; Through description to embodiment; Effect and operation principle, the manufacturing process of mutual alignment between the shape of specific embodiments of the invention such as related each member, structure, the each several part and annexation, each several part and manipulate method etc.; Do further detailed explanation, inventive concept of the present invention, technical scheme are had more complete, accurate and deep understanding to help those skilled in the art.
Like Fig. 4, the expressed structure of the present invention of Fig. 5, the present invention is a kind of heavy caliber ductile iron pipe core box, comprises core box base 2, half module 4 and plug 5; Described half module 4 is two of symmetries; Be installed on the core box base 2, through the branch resultant motion of guide rail 3, cylinder 1 and two half modules 4 of guide rod 7 realizations, endoporus one end of described half module 4; Cooperate with base plate 6, described half module 4, base plate 6 and plug 5 constitute the die cavity of cores 12.Drive half module 4 through cylinder 1, on the guide rail 3 of core box base 2, slide, realize the die sinking and the matched moulds of core box, produce cast tube and use core.
Establish base massive plate 11 on the above-described core box base 2, establish base gusset 12 on described base massive plate 11 lower surfaces.Spun cast pipe manufacturing technique requirent core has good dimensional accuracy and higher sand core strength, and in addition, its production efficiency also should satisfy batch production requirement.
In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective; The processing structure of massive plate is avoided in realization, reduces difficulty of processing, increases base intensity simultaneously; Reduce the goal of the invention of the possibility of distortion, the technical scheme that the present invention takes is:
As shown in Figure 3, the upper surface of the base massive plate 11 on the heavy caliber ductile iron pipe core box base provided by the present invention is provided with base and strengthens gusset 13, connects perhaps with screw to be welded on the base massive plate 11.
Its specific practice is: add at the contact area of core box base 2 and moving component and welded the thick steel plate of one deck 12mm.
From structural strength; Core box base 2 after the improvement has increased structural strength, has reduced the possibility of core box base 2 buckling deformations, can guarantee die sinking matched moulds smoothly; Guarantee the tightness of matched moulds; Guarantee the dimensional accuracy of core, reduce the labour intensity of workman's core finishing, improved the product qualified rate of pipe.
