AI Technical Summary
During the pressing process, the integral press head results in a high density at the center and a low density at the edges, which affects product quality.
A dual-zone pressing method with a central pressing plate and an outer pressing plate working together is adopted. By using a combination of low-stiffness spiral springs and high-stiffness disc springs, the paste is compacted in the center during the high fluidity stage and the edge is pressed to compensate for the low fluidity stage, thus ensuring uniform density.
It improves the density uniformity of the product, avoids looseness at the edges, especially in the corners, and increases the yield and quality of the finished product after demolding.

Abstract
Claims
1. A graphite sagger paste pressing and shaping device, characterized in that: Includes a press (11) and a mold (12), with a platform (13) mounted on the press (11) via an internal hydraulic mechanism at the lower end. The central pressure plate (21) and the outer pressure plate (22) respectively cover the central area and the edge area of the cavity of the mold (12). The central pressure plate (21) is fixedly connected to the platform (13), and the outer pressure plate (22) is fixedly connected to the platform (13) in a liftable manner. A low-stiffness helical spring (31) is fixed to the upper end of the outer pressure plate (22), and a high-stiffness disc spring (32) is fixed to the upper end of the low-stiffness helical spring (31). The upper end of the disc spring (31) is fixedly connected to the platform (13). The low-stiffness helical spring (31) and the high-stiffness disc spring (32) are evenly distributed above the outer pressure plate (22).
2. The graphite sagger paste press forming apparatus according to claim 1, wherein: A boss (33) is fixed at the junction of the low-stiffness helical spring (31) and the high-stiffness disc spring (32). A support rod (331) is fixed at the upper end of the boss (33) and passes through the platform (13) to form a sliding connection.
3. The graphite sagger paste press forming apparatus according to claim 2, wherein: The upper end of the support rod (331) is provided with a sliding groove (3311). When the high stiffness disc spring (32) is in the pre-compression state, the top surface of the sliding groove (3311) is located above the platform (13) and adjacent to its upper surface.
4. The graphite sagger paste press forming apparatus according to claim 3, wherein: The slide groove (3311) is equipped with a reciprocating sliding block (34), and the sliding direction is from the high stiffness disc spring (32) to the support rod (331).
5. The graphite sagger paste press forming apparatus according to claim 4, wherein: The upper end of the platform (13) is fixed with a support (35), and the end of the locking block (34) away from the support rod (331) is fixed with a sliding rod (342) which is slidably connected to the support (35).
6. The graphite sagger paste press forming apparatus according to claim 5, wherein: A blocking pad (3421) is fixed to the outside of the slide bar (342).
7. The graphite sagger paste press forming apparatus according to claim 4, wherein: The lower end of the card block (34) is an inclined guide slope (341) that covers the groove (3311).
