Embodiment Construction

[0012] Such as figure 1 , figure 2 and image 3 Shown, a kind of leak-proof mold box, comprises upper box 1 and lower box 2, the parting surface of described upper box 1 is provided with boss 3, and the parting surface of described lower box 2 is provided with convex platform. Table 3 corresponds to groove 4. The ring of the boss 3 is arranged on the parting surface of the upper case 1 . The groove 4 ring is arranged on the parting surface of the lower case 2 . The boss 3 cooperates with the groove 4. If there is molten steel flowing out and encountering such a structure, it will be blocked and cannot continue to flow outward. Some thin molten steel layers left on the parting surface will cool rapidly and be more sealed, which prevents The seepage of molten steel in the box is avoided, and the formation of steel breakout is avoided.

Abstract

The invention provides a leakproof casting box, comprising an upper box and a lower box, wherein the joint face of the upper box is provided with a boss, and the joint face of the lower box is provided with a groove corresponding to the boss. The casting box provided by the invention can prevent seepage of molten steel in the box, thus steel leakage is avoided.

Description

technical field [0001] The invention relates to the field of casting, in particular to a leak-proof casting mold box. Background technique [0002] Existing molded boxes are divided into an upper box and a lower box, both of which have flat parting surfaces, and when the boxes are closed, the upper and lower parting surfaces fit together to achieve sealing, so that the molten steel in the cavity will not flow out. However, in actual operation, it is inevitable that there will be lax fit and partial edge warping, so that molten steel will seep out from the gap between the parting surfaces of the upper box and the lower box, forming a leak, commonly known as "fire escape". . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a leak-proof casting mold box, which can prevent the leakage of molten steel in the box and avoid the formation of breakouts. [0004] In order to solve the above-mentioned existing technical pr...
