AI Technical Summary
⚠Technical Problem
The pressure holding mechanism of a traditional hot press has inconsistent sealing directions when facing vacuuming and pressurization, which can lead to pressure loss or self-pressurization, affecting the stability of the hot pressing process.
⚗Method used
An adaptive pressure-holding mechanism was designed. By setting a flip-up sealing protrusion and a sliding sealing strip on the flip plate, the sealing direction is automatically adjusted according to the air pressure direction to ensure the sealing effect of the gas channel.
🎯Benefits of technology
It achieves automatic adaptation to sealing under different air pressure conditions, improves the stability and sealing effect of the hot pressing process, and avoids the occurrence of pressure leakage or self-pressurization.

Abstract
The application relates to the technical field of hot presses, and discloses a self-adaptive pressure maintaining mechanism for a hot press, which comprises a fixing frame, a hot pressing plate slidingly arranged on the fixing frame, and a cylinder arranged on the fixing frame and connected with the hot pressing plate, wherein the cylinder is used for providing pressure for the hot pressing plate. The self-adaptive pressure maintaining mechanism for the hot press is provided with a fixed plate in a pressure maintaining and regulating bin, a notch is formed in the fixed plate, a turnover plate is arranged in the notch, the turnover plate and the fixed plate are rotationally connected through a rotating shaft, a through hole is formed in the turnover plate, the gas delivered or extracted by the cylinder enters or exits through the through hole, a sealing lug is slidably arranged on the turnover plate, the sealing lug can open and close the through hole, the sealing lug on the turnover plate can adaptively seal the through hole under two different air pressure conditions by rotating the turnover plate, the sealing effect of the through hole is enhanced, and the pressure relief direction is adapted.
