[0037] The working principle and use process of the present invention are as follows: when in use, the raw material is laid flat on the top of the movable heating support plate 23, and then the third deformable position adjusting member 55 is controlled to extend, and the movable pressing plate 50 is moved downward by the extension of the third deformable position adjusting member 55, and the movable pressing plate 50 that moves downward cooperates with the movable heating support plate 23 to extrude the raw material. At the same time, the power supply of the movable heating support plate 23 is turned on to heat the raw material, and the first rotatable assembly plate 24 and the second rotatable assembly plate 25 are used to realize the molding of the material;

[0038] After the workpiece is shaped, the movable pressing plate 50 is controlled to move upward to restore the movable pressing plate 50 to its initial position, and then the third deformable position adjusting member 55 is further controlled to contract to allow the movable pressing plate 50 to move further upward, so that the movable pressure regulating piston 52 is inserted into the interior of the air supply metal box 54, and the air in the air supply metal box 54 is squeezed by the continuous upward movement of the movable pressure regulating piston 52, so that the air in the air supply metal box 54 enters the interior of the movable air storage box 285 after being transported by the air supply support pipe 3. At this time, the fifth limiting bearing metal plate 287 moves upward under the action of air pressure, so that the formed sheet is lifted up by the upwardly moved fifth limiting bearing metal plate 287, so that the sheet is separated from the contact with the movable heating support plate 23, and the sheet is demolded. At the same time, the air in the movable air storage box 285 is continuously discharged to the outside through the limiting exhaust hole 26, so as to achieve air cooling of the sheet;

[0039] In addition, the first deformable position adjusting member 27 is controlled to extend so that the fourth limit bearing metal plate 22 is moved up to the top of the posture adjusting box 21. At this time, the first rotatable assembly plate 24 and the second rotatable assembly plate 25 lose the restraint of the posture adjusting box 21 and thus flip outward, and cooperate with the fifth limit bearing metal plate 287 to strip the plate, thereby realizing all-round stripping and all-round rapid and sufficient cooling of the plate, which is convenient for users to take out the processed plate, and through cooling, it is convenient for users to perform subsequent processing on the plate, so as to improve the user's production efficiency. In addition, the user can control the position of the movable pressing plate 50 to process plates of different thicknesses through the mold, thereby realizing the production and processing of plates of different models and improving the applicability of the mold;

[0040] Therefore, through the mutual cooperation of multiple structures, the user can adjust the applicability of the mold so that the mold can be suitable for the production of different types of polytetrafluoroethylene sheets, making the application range of the mold wider. Secondly, the present invention can be quickly deformed through the mutual cooperation of multiple structures to achieve rapid material removal and rapid and sufficient cooling of the workpiece through the change of the mold shape, thereby improving the production efficiency of the mold. In addition, the present invention has a simple structure, is easy to use, and is worthy of promotion and use.

[0041] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
