This regular arrangement makes the pressure of the working mold surface 400 and the material to be processed uniformly distributed on each mold surface support mechanism 200, thereby improving the stability of the entire mold, and the array gap can create conditions for the flow of high-temperature gas, improving the convective heat transfer efficiency.

[0036] As shown in Figure 2 , the die face support mechanism 200 includes a stepping motor 201 installed at one end of the bottom of the die base 120, the main shaft of the stepping motor 201 is connected with one end of the height adjustment screw 203 through the shaft coupling 202, the height adjustment screw 203 is externally threaded with the die face support sleeve, the die face support sleeve is matched with the bottom of the working die face 400 through the mortise and tenon structure, and the die face support sleeve includes the upper die face support sleeve 206 through the H-shaped connecting sleeve 205 and the lower die face support sleeve 204 matched with the height adjustment screw 203.

[0038] When disassembling the working die surface 400, the outer air pump passes through the mortise and tenon two-way valve 213 to inject high-pressure air into the annular cavity, the circular ring, the side offset reset pad 212 and the sealing sliding block 215 of the L-shaped mortise and tenon jaw 208 move upward, compress the gripping spring 211, and due to the cooperation of the mortise and tenon rod 214 with the three arc-shaped jaws, the three arc-shaped jaws are gradually expanded to separate the three arc-shaped jaws from the ball tenon connecting part 401, so that the working die surface 400 and the die surface supporting mechanism 200 are disassembled and completed.

[0039] When installing the working die surface 400, the outer air pump passes through the mortise and tenon two-way valve 213 to extract air from the annular cavity, the circular ring, the side offset reset pad 212 and the sealing sliding block 215 of the L-shaped mortise and tenon jaw 208 move downward, and the gripping spring 211 is restored. Due to the cooperation of the mortise and tenon rod 214 with the three arc-shaped jaws, the three arc-shaped jaws are gradually contracted to lock the three arc-shaped jaws with the mortise and tenon type ball tenon connecting part 401, so that the working die surface 400 and the die surface supporting mechanism 200 are installed and completed.

[0040] As shown in Figures 5-8 The mortise and tenon structure includes a mortise and tenon structure arranged in the die surface supporting sleeve and one end out, the mortise and tenon structure includes an L-shaped mortise and tenon jaw 209 nested in the upper die surface supporting sleeve 206 one end opening, the L-shaped mortise and tenon jaw 209 one end is provided with at least three arc-shaped inlays 2091 cooperating with the annular mortise sleeve 402 installed at the bottom of the working die surface 400, the other end of the L-shaped mortise and tenon jaw 209 is a ring-shaped part installed in the upper die surface supporting sleeve 206 and cooperates with the top of the H-shaped connecting sleeve 205, the inside of the L-shaped mortise and tenon jaw 209 passes through the stepped cylinder 217, the small diameter end of the stepped cylinder 217 passes through the middle spacer of the H-shaped connecting sleeve 205 and is threadedly connected with the cylindrical washer 2171, the small diameter end of the stepped cylinder 217 is sleeved with an unlocking spring 210, the unlocking spring 210 cooperates with the middle spacer and the cylindrical washer 2171, and the large diameter end of the stepped cylinder 217 is arranged in the annular cavity formed by the top of the H-shaped connecting sleeve 205 and the bottom of the upper die surface supporting sleeve 206. The side surface of the upper die surface supporting sleeve 206 is provided with a mortise and tenon two-way valve 216 in communication with the annular cavity.

[0041] When installing the working die surface 400, the outer air pump passes through the mortise and tenon two-way valve 216 to inject air into the annular cavity, the stepped cylinder 217 moves upward, and the unlocking spring 210 is compressed. Since the three arc-shaped inlays 2091 are initially concentrated together in a conical shape, when the stepped cylinder 217 moves upward, the large diameter cooperates with the three arc-shaped inlays 2091, the three arc-shaped inlays 2091 are gradually expanded, and the three arc-shaped inlays 2091 are matched with the annular mortise sleeve 402, so that the working die surface 400 and the die surface supporting mechanism 200 are installed and completed.

[0042] When the working die surface 400 is disassembled, the stepped cylinder 217 moves downward by the outside air pump through the tenon two-way valve 216 to the annular cavity, and the unlocking spring 210 is restored. When the stepped cylinder 217 moves downward, the large diameter is matched with the three arc-shaped fillets 2091, the three arc-shaped fillets 2091 are gradually contracted, the three arc-shaped fillets 2091 are separated from the inner edge of the annular mortise sleeve 402, and the working die surface 400 is disassembled with the die surface supporting mechanism 200.

[0043] As shown in Figure 10 and 11 The flexible composite structure mold is symmetrically arranged, first, the corresponding working die surface 400 is replaced according to the metal plate or non-metal plate to be processed, the alloy plate or non-metal plate is placed on the working die surface 400, the modeling is carried out in the flexible composite structure mold special software according to the numerical model of the plate curved surface part, the height data of each die surface supporting mechanism is calculated through the multi-point process, and the data (corresponding to the die surface supporting mechanism data) is sent to the motor circuit board of the specified die surface supporting mechanism, the motor is powered to rotate, the screw drives the cube to move up and down, and the program in the circuit board always compares the die surface supporting mechanism height (real-time) with the die surface supporting mechanism calculation height data (specific data). When the die surface supporting mechanism height is consistent with the die surface supporting mechanism calculation height data, the motor stops.

[0044] Suppose the screw pitch T=2mm, and the stepping motor rotates 0.18 degrees per pulse. Therefore, the motor needs 360 degrees / 0.18=2000 pulses to rotate one circle. The die surface supporting mechanism moves 2 / 2000=0.001mm per pulse. The stepping motor compares the die surface supporting mechanism height every pulse, and stops when the die surface supporting mechanism height is greater than the die surface supporting mechanism calculation height data. The maximum positioning error of the die surface supporting mechanism is 0.001mm. Therefore, the die surface supporting mechanism can be called accurate shaping. The thread between the lower die surface supporting sleeve and the screw is self-locking, so the die surface supporting mechanism will not retract no matter how large the force is. Only the motor driven die surface supporting mechanism cube can extend or retract the height. Therefore, the alloy plate or non-metal plate is pressed and formed by the upper and lower working die surfaces 400.

[0045] Although the embodiments of the present application have been disclosed as above, it is not limited to the application listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present application. Those skilled in the art can easily make other modifications. Therefore, the present application is not limited to specific details and the figures shown and described herein without departing from the general concept defined by the claims and the equivalent scope.
