The rod 4 is threaded and matched with the nut 5. The rod 4 and the mounting hole 2 are interference fit, which completes the connection and fastening.

[0038] Example 2, as Figure 2 As shown:

[0061] The shaft 1 is made of high-strength, high-wear-resistant material. The size of the mounting hole 2 matches that of the rod 4 to ensure a tight interference fit. Depending on specific requirements, semi-circular, rectangular, circular, or square blind holes can be selected. The interference fit between the mounting hole 2 and the rod 4 ensures a tight connection between the rod 4 and the shaft 1, improving the stability of the entire device and reducing malfunctions caused by loose connections. The spiral structure on the outer surface of the shaft 1 and the specially shaped mounting hole 2 facilitate smooth material transport and uniform distribution, thereby improving the molding quality of ceramic products and reducing internal defects and dimensional deviations. The support plate 8 and through hole 10 inside the shaft 1 are designed... The design optimizes the mechanical and heat dissipation properties of the shaft 1 without compromising strength. A suitable spiral structure, such as threaded grooves 6, threaded protrusions 7, or spiral blades 9, is selected based on the characteristics of the ceramic castable (e.g., viscosity and flowability). The spiral structure is fabricated on the outer surface of the shaft 1 using methods such as mold forming or machining, ensuring that its dimensions and shape meet requirements. This ceramic castable molding shaft structure, through its reasonable connection method, optimized outer surface spiral structure, and internal support and through-hole design 10, effectively solves the problems of connection stability, material conveying, molding quality, and structural strength in traditional molding shafts, meeting the needs of high-quality ceramic product production.
