The variety of vortex shower nozzle is numerous, when the hollow vortex shower nozzle of production, receives the influence of structure and need use two wax matrix to cast the shaping respectively, then carries out the amalgamation with two wax matrix after the shaping fixed, and this kind of mode is widely used at present.

Due to the adoption of split casting molding, the operation process becomes complicated and troublesome, and the production efficiency is difficult to improve. Meanwhile, the splicing process of the wax molds is manually operated, so that the molding quality of products is uneven, and the standards are difficult to unify. In addition, the spliced wax pattern model has the phenomena of rough and uneven inner and outer splicing surfaces, accumulation and the like, so that the size precision of a product in the final casting link is not enough, the final bad part rate of the product is high, and the phenomenon of furnace return is very common. In addition, if a gap is formed on the splicing surface carelessly, quality and safety accidents such as leakage and the like are easy to occur in the using process.

Disclosure of Invention

The utility model aims at solving the technical problem that the inconvenient easy product casting shaping quality that influences of split type wax matrix operation exists in prior art, providing a novel wax matrix shaping integral type gum cover to overcome prior art not enough.

The utility model relates to a novel wax mould forming integrated rubber sleeve, which comprises a spherical rubber body with a hollow structure; the upper end and the lower end of the spherical rubber body are respectively provided with an upper through hole and a lower through hole;

an upper convex ring is arranged at the edge of the upper through hole; the outer diameter of the upper protruding ring is gradually reduced from one end close to the upper through hole to one end far away from the upper through hole to be in a closed-up shape;

a lower convex ring is arranged at the edge of the lower through hole; the outer diameter of the lower protruding ring is gradually reduced from one end close to the lower through hole to one end far away from the lower through hole to be in a closed-up shape;

a first fixing hole penetrating through the spherical rubber body is formed in the horizontal center line of the spherical rubber body; the first fixing hole is correspondingly arranged on one side of the longitudinal center line of the spherical rubber body, and the outer edge of the first fixing hole is externally tangent to the longitudinal center line of the spherical rubber body;

and a second fixing hole which is coaxial with the first fixing hole and corresponds to the inner wall of the spherical rubber body is formed in the inner wall of the spherical rubber body, and the second fixing hole is not communicated with the spherical rubber body.

Further, the inner diameters of the first fixing hole and the second fixing hole are the same.

Further, the spherical rubber body, the upper convex ring and the lower convex ring are integrally formed.

Further, the thickness of the spherical rubber body is respectively consistent with the thickness of the upper convex ring and the lower convex ring, and the connecting parts are in smooth transition.

Further, the spherical rubber body is of a flat-ball-shaped structure.

The utility model has the advantages that the whole material is rubber, soft and easy to deform and take out; go up protruding ring and protruding ring down can do benefit to the location shaping of wax matrix, and the wax matrix receives the effect of protruding ring and protruding ring down promptly and can the integrated into one piece, and it can to utilize specialized tool to take out the gum cover from the wax matrix upper through-hole department after the design or through-hole department down after the shaping. The formed wax pattern is used for forming a molten steel mould.
