The forming mold includes a rectangular cylinder 2, and the lower end of the rectangular cylinder 2 is connected to a support frame 6 for support. The lower ejecting mechanism includes a bottom support plate 3 installed in the rectangular cylinder 2 and adapted to the inner hole of the rectangular cylinder 2, and a first power mechanism for driving the bottom support plate 3 to lift and adjust along the height direction of the rectangular cylinder 2 is installed on the support frame 6. The upper and lower pressing mechanism includes a pressing plate 13 that can enter and exit the rectangular cylinder 2 and can lift and adjust along the height direction of the rectangular cylinder 2. A swing-adjustable bracket is installed at the upper end of the rectangular cylinder 2, and a second power mechanism for driving the pressing plate 13 to lift is installed on the bracket.

[0022] In this embodiment, a cross brace 5 is provided on the support frame 6. The first power mechanism is a first cylinder 4. The cylinder body of the first cylinder 4 is fixed to the cross brace 5, and the piston rod of the first cylinder 4 is connected to the bottom support plate 3. The bottom support plate 3 is lifted under the drive of the first cylinder 4. When the bottom support plate 3 rises, the formed tofu block can be ejected from the rectangular cylinder 2. When the rectangular cylinder 2 needs to be cleaned, the bottom support plate 3 can be operated to descend and move out of the rectangular cylinder 2, and the rectangular cylinder 2 can be cleaned by flushing with water.

[0023] In this embodiment, liquid outlet holes 7 are evenly distributed on the four vertical surfaces of the rectangular cylinder 2. Excess water in the tofu brain can be discharged from the liquid outlet holes 7 in the pressing state. At the same time, in order to prevent the tofu brain from overflowing from the liquid outlet holes 7, filter cloth 8 is covered on the inner wall of each vertical surface of the rectangular cylinder 2.

[0024] In this embodiment, the bracket includes a column 10 and a cross beam 11. The column 10 and the cross beam 11 are perpendicularly and fixedly connected. A bearing seat 9 is installed on the rectangular cylinder 2, and the lower end of the column 10 is connected to the bearing seat 9. With the help of the bearing seat 9, the rotation adjustment of the bracket can be realized. When the pressing plate 13 is in use, by rotating, the pressing plate 13 is aligned with the opening on the rectangular cylinder 2. When the pressing plate 13 is not in use, by rotating, the pressing plate 13 is moved away from the rectangular cylinder 2 to avoid interfering with other operations.

[0025] Further, the second power mechanism is a second cylinder 12. The cylinder block of the second cylinder 12 is fixed to the cross beam 11, and the piston rod of the second cylinder 12 is connected to the pressing plate 13. The lifting of the pressing plate 13 is realized under the drive of the second cylinder 12.

[0026] In this embodiment, the lifting mechanism includes a support plate 18 and a tray 14 whose height can be adjusted up and down. The tray 14 is connected to the support plate 18 through a support assembly. One end of the support plate 18 is fixed to the rectangular cylinder 2, and the other end of the support plate 18 is supported by a support leg 19. The support assembly includes two vertically arranged screw rods 15. The upper end of each screw rod 15 is fixed to the tray 14, and the lower end of each screw rod 15 passes through the support plate 18. An upper fixing nut 16 and a lower fixing nut 17 are respectively threadedly connected to each screw rod 15, and the upper fixing nut 16 and the lower fixing nut 17 are respectively located on the upper and lower sides of the support plate 18. By cooperatively adjusting the positions of the upper fixing nut 16 and the lower fixing nut 17, the height adjustment of the tray 14 can be realized, and the height where the tray 14 is located can be adjusted according to the cutting thickness of the tofu.

[0027] Further, a baffle 20 for limiting the storage basket 1 is provided on the tray 14.

[0028] During specific use, the tofu curd is poured into the rectangular cylinder 2. At this time, the bottom support plate 3 blocks the lower opening of the rectangular cylinder 2. The pressing plate 13 is operated to descend and press the tofu curd, and the excess water in the tofu curd can be discharged from the liquid outlet hole 7. As Figure 2 shown, after the tofu is formed, the pressing plate 13 is removed, and the first cylinder 4 pushes the bottom support plate 3 to rise, and the formed tofu block 21 is gradually pushed out of the rectangular cylinder 2. After the tofu block is pushed out to an appropriate height, the bottom support plate 3 pauses to rise. The storage basket 1 is placed on the tray 14, and the top surface of the storage basket 1 is flush with the top surface of the rectangular cylinder 2. The pushed-out part of the tofu block 21 is cut off and moved into the storage basket 1. Then, a new storage basket 1 is replaced, and the newly pushed-out and cut tofu blocks are moved into the new storage basket 1.

[0029] The rectangular cylinder 2 has a large capacity, and a large piece of tofu can be formed by one-time pressing. With the help of the lower pushing-out mechanism, the large piece of tofu can be gradually pushed out and cut into small pieces. At the same time, with the help of the lifting mechanism, the small pieces of tofu can be received and transferred. After the structure is improved, the processing efficiency can be significantly improved, and it has a certain popularization prospect in the tofu production industry.
