[0032] The utility model is described in detail below with reference to the accompanying drawings.

[0033] like Figure 1-4 As shown, a processing jig for correcting flatness of large-sized products includes a mold 1 and a driving mechanism for driving the mold 1 to open and close the mold. The mold 1 includes an upper mold 11 and a lower mold 12. The upper mold 11 is formed with a top mold cavity 13, and the lower mold 12 is formed with a bottom mold cavity 14. The top mold cavity 13 includes a plane groove 15, and the plane groove 15 has an arc. The bottom mold cavity 14 includes a plane block 16 that cooperates with the plane groove 15, and the plane block 16 has an arc. The driving mechanism includes a lifting drive member 2 that drives the upper mold 11 to move longitudinally.

[0034] During processing, the upper mold 11 is driven by the lifting drive member 2 to continuously approach the lower mold 12 to achieve mold closing. After mold closing, the upper mold 11 is always kept in close contact with the lower mold 12 by the lifting drive member 2, which can ensure that the flatness of the molded product meets the requirements; in addition, the planar groove 15 of the top mold cavity 13 has a certain curvature, and correspondingly, the bottom mold cavity 14 has a curved planar block 16. When molding large-sized products, combined with the high temperature in the top mold cavity 13 and the bottom mold cavity 14, the probability of product deformation can be reduced, and its flatness can be further corrected, and the product quality is better.

[0035] Furthermore, the lifting drive member 2 is provided with a pair of connecting plates 31 which can move longitudinally, the bottom of the connecting plate 31 is connected to the top surface of the upper mold 11, a connecting block 3 is provided between the two connecting plates 31, and the distance between the two connecting plates 31 can be adjusted; the two connecting plates 31 are connected to the upper mold 11 at the same time, which increases the contact area and further improves the connection stability. By changing the distance between the two connecting plates 31 through the connecting block 3, upper molds 11 of different sizes can be connected, and the adaptability is better.

[0036] The driving mechanism further includes a support base 21 for supporting the lower mold 12. The mold 1 is mounted on the support base 21 so that its horizontal position can be adjusted. The support base 21 is formed with a track groove 17 along its length, and a sliding block 18 that slidably cooperates with the track groove 17 is mounted at the bottom of the lower mold 12. After the mold 1 is placed on the support base 21, the position of the mold 1 can be adjusted by the sliding cooperation of the sliding block 18 and the track groove 17, so that the connecting plate 31 is longitudinally aligned with the mold 1.

[0037] The track groove 17 is also slidably mounted with a limit seat 19. After the position of the mold 1 is adjusted, the limit seat 19 moves to both sides of the mold 1 to prevent the mold 1 from shifting and ensure that the connection plate 31 and the mold 1 are vertically aligned.

[0038] A supporting column 22 is installed on the top of the supporting base 21, and a transversely arranged driving plate 23 is installed on the top of the supporting column 22. The lifting driving component is a lifting cylinder 24 installed on the driving plate 23. The driving end of the lifting cylinder 24 is transmission-connected to the connecting plate 31. Driven by the lifting cylinder 24, the upper mold 11 can move longitudinally to realize mold opening and closing.

[0039] The driving plate 23 is provided with a guide hole 25, in which a guide sleeve 26 is installed. A guide rod 27 is installed on the top of the connecting plate 31. The guide rod 27 can move along the axial direction of the guide sleeve 26. Through the sliding cooperation between the guide rod 27 and the guide sleeve 26, the linear movement stability of the upper mold 11 can be further improved.

[0040] The driving plate 23 is also provided with a driving hole 28, and a lifting rod 29 is installed at the driving end of the lifting cylinder 24. The lifting rod 29 passes through the driving hole 28, and the end of the lifting rod 29 is connected to the connecting block 3. The lifting rod 29 of the lifting cylinder 24 moves in the vertical direction and moves longitudinally from the driving hole 28, thereby driving the connecting block 3 to move up and down, and the connecting plate 31 connected to the connecting block 3 to move up and down, thereby realizing the closing and opening of the upper mold 11.

[0041] A limiting sleeve 38 having an outer diameter greater than that of the guiding sleeve 26 is installed on the top of the guiding rod 27 , and the limiting sleeve 38 prevents the guiding rod 27 from falling off from the guiding hole 25 .

[0042] A wedge block 32 is formed at the bottom of the guide rod 27, and a transversely arranged wedge groove 33 is formed on the top of the connecting plate 31. The wedge block 32 can move laterally in the wedge groove 33, and limit blocks 34 are installed at both ends of the wedge groove 33 to prevent the wedge block 32 from detaching; through the sliding cooperation of the wedge block 32 and the wedge groove 33, the connection position of the connecting plate 31 and the guide rod 27 can be adjusted, so that the distance of the connecting plate 31 is adjustable, and for the connection of molds 1 of different sizes, the connection stability between the upper mold 11 and the connecting plate 31 is better.

[0043] Preferably, a finger cylinder 35 is installed at the bottom of the connecting plate 31, and clamping plates 36 are respectively installed at the two driving ends of the finger cylinder 35. The clamping plates 36 are connected to the connecting plate 31. Under the drive of the finger cylinder 35, the distance between the two connecting plates 31 changes accordingly.

[0044] The support base 21 is also equipped with a cooling pipe 37 for discharging coolant; when the mold 1 needs to be cooled, the coolant can be sprayed onto the surface of the mold 1 for rapid cooling.

[0045] In summary, it can be seen that the utility model has the above-mentioned excellent characteristics, which can enhance the performance unprecedented in the prior art and become a product with great practical value.
