[0028] As Figures 1 to 3 shown, this embodiment provides a large O-ring vulcanization device 100, which includes upper and lower groups of corresponding mounting seats 20 and a base 40. And on the end face of the mounting seat 20 close to the base 40 is used to install an upper mold. A movable plate 50 is arranged between the mounting seat 20 and the base 40, and the movable plate 50 is driven by a lifting system 60; the lower mold is installed on the movable plate 50; the mounting seat 20 and the base 40 are connected by a support system 10.

[0029] Furthermore, a plurality of upper ear seats 103 are evenly distributed along the circumference on the side end face of the mounting seat 20, and a plurality of lower ear seats 102 are evenly distributed along the circumference on the side end face of the base 40. And a support column 101 is arranged between the upper ear seat 103 and the lower ear seat 102.

[0030] Furthermore, the distance between the center lines of two adjacent groups of the support columns 101 is L, and the distance L is 100 mm - 650 mm, preferably 642 mm.

[0031] In this embodiment, the connection between the mounting seat 20 and the base 40 is realized by adding support columns 101. When the distance L between the center lines of two adjacent groups of the support columns 101 is 642 mm, the deformation amount between the mounting seat and the base can be better reduced.

[0032] The large O-ring is a common rubber sealing ring, mainly playing a sealing role. When producing large O-rings, most are produced by a flat vulcanizing machine. Multiple sections of sealing strips are produced by the flat vulcanizing machine, and then the multiple sections of sealing strips are spliced and subjected to secondary vulcanization to form a large O-ring. However, the splicing joints of the large O-rings produced by the above method are extremely prone to breakage, and the process is complex, with low efficiency and high production costs. To solve the above technical problems, please refer to Figures 1 to 3 As shown, the lifting system 60 includes multiple groups of hydraulic cylinders 601; and they are evenly distributed along its circumferential direction. The distance between the centerlines of adjacent two groups of hydraulic cylinders 601 is M, and M is 100 - 550 mm; the centerline of one group of the hydraulic cylinders 601 intersects with the centerline of the vulcanizing equipment to form an included angle β, and the included angle β is 15° - 46°, preferably 42.6°;

[0033] The extension line of the centerline of the hydraulic cylinder adjacent to it intersects with the centerline of the vulcanizing equipment to form an included angle ɑ, and the included angle ɑ is 5° - 20°, preferably 18°.

[0034] In this embodiment, through multiple groups of hydraulic cylinders 601 evenly distributed along the circumferential direction, the uniform distribution of pressure during the production of large O-rings is ensured, facilitating the one-time forming of large O-rings and improving the overall strength and working efficiency.

[0035] Furthermore, the hydraulic cylinder 601 can withstand a pressure of 100 N.

[0036] When producing large O-rings, the number of hydraulic cylinders and the distance M between the centerlines of adjacent two groups of hydraulic cylinders 601 can be selected according to the diameter of the large O-ring;

[0037] For example: when producing a large O-ring with a diameter of 3.96 m, the number of required hydraulic cylinders is 20.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than restrictive. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that any modification or equivalent replacement of the technical solutions of the present invention does not depart from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
