[0026] Furthermore, a controller is installed on the right side of the connecting plate 5, and the heating furnace 2, the first electric push rod 6, and the second electric push rod 8 are electrically connected to the controller.

[0027] Through the cooperation of heating furnace 2, lower mold 3, upper mold 4, connecting plate 5, first electric push rod 6, sealing plate 7, second electric push rod 8, adjusting plate 9, movable plate 10 and base 11, a heat treatment device for high-precision manufacturing of titanium alloys is realized. The workpiece is directly placed on the lower mold 3 and heated by heating furnace 2. Then, the heated workpiece is extruded and shaped by the two molds, thereby improving the efficiency of workpiece processing and avoiding the need to transfer the heated workpiece to an external forming mold for processing.

[0028] Two slots 12 are provided on the front sides of the two bases 11, on opposite sides. A plug 13 is fixedly connected to the top of the movable plate 10 and the bottom of the adjusting plate 9, corresponding to the slot 12. The plug 13 extends through the slot 12 and into its interior, contacting the inner wall of the slot 12. Movable moving plates 14 are provided at the bottom of the movable plate 10 and the top of the adjusting plate 9. The bottom moving plate 14 contacts the top of the movable plate 10, and the top moving plate 14 contacts the bottom of the adjusting plate 9. A locking block 15 is fixedly connected to the side of the moving plate 14 near the base 11. A slot 16 adapted to the locking block 15 is provided on the side of the base 11 near the locking block 15. The bottom locking block 15, near the slot 16, extends through the movable plate 10 and the bottom slot 16, reaching into the slot 16 and contacting its inner wall. The top-mounted locking block 15, near the side of the locking slot 16, passes through the adjusting plate 9 and the top-mounted locking slot 16, extending into the inside of the locking slot 16 and contacting the inner wall of the locking slot 16. The bottom of the movable plate 10 and the top of the adjusting plate 9 are both provided with fixing slots 17. A fixing plate 18 is fixedly connected to the inner wall of the fixing slot 17. Two moving rods 19 are fixedly connected to the side of the movable plate 14 near the fixing plate 18.

A stop block 20 is provided inside the fixing slot 17. One end of the moving rod 19 near the stop block 20 is fixedly connected to the stop block 20. The side of the stop block 20 near the inner wall of the fixing slot 17 contacts the inner wall of the fixing slot 17. A buffer spring 21, model GH 4169, is sleeved on the surface of the moving rod 19 and has high-temperature resistance.

[0029] Furthermore, two push blocks 22 are provided on the right side of the base 11. The two push blocks 22 are respectively fixedly connected to the two moving plates 14 by connecting blocks 23 on the side that is far away from each other. By setting push blocks 22 and connecting blocks 23, it is convenient to operate the moving plates 14, so that the card block 15 can be quickly separated from the card slot 16.

[0030] Specifically, the mold needs to be disassembled for maintenance and repair. Push the push block 22 so that the two push blocks 22 move away from each other. The push block 22 drives the moving plate 14 away from the base 11 through the connecting block 23. The moving plate 14 drives the stop block 20 to squeeze the buffer spring 21 through the moving rod 19. The moving plate 14 drives the locking block 15 away from the locking slot 16 so that the locking block 15 and the locking slot 16 separate. Then the lower mold 3 or the upper mold 4 can be pulled backward so that the base 11 drives the slot 12 to move backward and separate from the insertion block 13, so that the two molds can be disassembled.

[0031] The interplay of slot 12, insert block 13, moving plate 14, locking block 15, locking groove 16, fixing groove 17, fixing plate 18, moving rod 19, stop block 20, buffer spring 21, push block 22 and connecting block 23 facilitates the disassembly of the two molds for maintenance and repair, thereby improving the service life of the molds.

[0032] In use, place the titanium alloy plate on the lower mold 3, and then start the first electric push rod 6. The first electric push rod 6 drives the movable plate 10 to move to the left through the sealing plate 7. The movable plate 10 drives the lower mold 3 and the titanium alloy plate to move into the heating furnace 2, so that the sealing plate 7 and the right side of the heating furnace 2 are in close contact, sealing the heating furnace 2, and heating the workpiece through the heating furnace 2.

[0033] After heating is completed, the first electric push rod 6 drives the lower mold 3 and the workpiece to move to the right, so that the lower mold 3 and the workpiece are pulled out of the heating furnace 2 and returned to their original positions. At this time, the position of the workpiece can be adjusted by external clamps to ensure that the workpiece is located in the center of the lower mold 3. Then, the second electric push rod 8 is started. The second electric push rod 8 drives the upper mold 4 to move downward through the adjusting plate 9, so that the upper mold 4 and the lower mold 3 close together to extrude and form the workpiece.
