[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] The embodiment of the present application provides a solid tire mold with multiple cavities in one mold, which can simultaneously produce multiple specifications and multiple solid tires, greatly improving the tire production capacity, and the cavities are interchangeable.

[0035] The positional relationship of each component described in the following embodiment of a solid tire mold with multiple cavities is based on Figure 1 As the basis.

[0036] See also Figures 1 to 8 The embodiment of the present application provides a solid tire mold with multiple cavities, including:

[0037] A mold body 1, a plurality of interchangeable cavities 2 and an interchangeable cavity positioning ring 3;

[0038] The mold body 1 includes an upper mold body 101 and a lower mold body 102, and the upper mold body 101 and the lower mold body 102 are closed to form a shell of the mold;

[0039] A plurality of interchangeable cavities 2 are located inside the mold body 1, and the interchangeable cavities 2 include an upper interchangeable cavity 201 and a lower interchangeable cavity 202, and the shape and size of the solid tire are formed by the upper interchangeable cavity 201 and the lower interchangeable cavity 202;

[0040] The interchangeable cavity positioning ring 3 comprises an upper interchangeable cavity positioning ring 301 and a lower interchangeable cavity positioning ring 302. When the mold is closed or opened, the upper interchangeable cavity positioning ring 301 and the lower interchangeable cavity positioning ring 302 cooperate with each other for positioning.

[0041] It should be noted that the mold designed in the embodiment of the present application is mainly composed of a mold body 1 and a plurality of interchangeable cavities 2, such as Figure 1 Four interchangeable cavities 2 are given as examples, and these interchangeable cavities 2 are detachable and replaceable. Specifically, the mold body 1 includes an upper mold body 101 and a lower mold body 102 that are symmetrical to each other, which together constitute the outer shell of the mold, and are used to drive the opening and closing of multiple interactive cavities 2 and complete the heating and vulcanization of the solid tire. The material fully considers the characteristics of wear resistance, toughness, fatigue fracture performance, high temperature performance, corrosion resistance, etc., for example, 45# steel is used.

[0042] In addition, each interchangeable mold cavity 2 includes an upper interchangeable mold cavity 201 and a lower interchangeable mold cavity 202, and the upper interchangeable mold cavity 201 and the lower interchangeable mold cavity 202 together constitute an annular mold cavity for shaping and vulcanizing the solid tire.

[0043] At the same time, the mold is also provided with an interchangeable cavity positioning ring 3 for positioning to ensure that the solid tire steel ring is accurately positioned during vulcanization. Specifically, the interchangeable cavity positioning ring 3 includes an upper interchangeable cavity positioning ring 301 and a lower interchangeable cavity positioning ring 302, and its specific functions are: when the solid tire embryo is loaded, the positioning of the lower interchangeable cavity positioning ring 302 prevents the solid tire steel ring from being out of center; when the mold is closed, the upper interchangeable cavity positioning ring 301 is used for further positioning to ensure that the solid tire steel ring is accurately positioned during vulcanization.

[0044] It should be noted that the specific steps of vulcanization and mold opening are as follows: Figures 4 to 7First, after the vulcanization is finished and the mold is opened to take out the solid tire, the ejection mechanism of the ejector will eject the lower interchangeable cavity positioning ring 302. The vulcanized solid tire is positioned with the lower interchangeable cavity positioning ring 302, and also follows the lower interchangeable cavity positioning ring 302 to detach from the lower interchangeable cavity 202 under the action of the lower interchangeable cavity positioning ring 302; then, the tire receiving device is extended and placed under the solid tire, and the ejection mechanism of the mold machine slowly descends. The lower interchangeable cavity positioning ring 302 follows the ejection mechanism due to the effect of gravity and finally falls back into the lower interchangeable cavity 202. The solid tire is held by the tire receiving device and remains in the original position. The manipulator moves in, grabs the solid tire, and rotates it out and puts it into the designated position; finally, the tire receiving device is extended back, and the manipulator grabs the new tire embryo, puts it into the mold, and vulcanizes it again.

[0045] In an embodiment of the present application, a one-mold, multi-cavity solid tire mold is designed, including a mold body 1, a plurality of interchangeable cavities 2, and an interchangeable cavity positioning ring 3, wherein the mold body 1 includes an upper mold body 101 and a lower mold body 102, the upper mold body 101 and the lower mold body 102 are combined to form a mold shell, and the plurality of interchangeable cavities 2 are located inside the mold body 1, the interchangeable cavity 2 includes an upper interchangeable cavity 201 and a lower interchangeable cavity 202, and the shape and size of the solid tire are formed by the upper interchangeable cavity 201 and the lower interchangeable cavity 202; the interchangeable cavity positioning ring 3 includes an upper interchangeable cavity positioning ring 301 and a lower interchangeable cavity positioning ring 302, and when the mold is closed and opened, the upper interchangeable cavity positioning ring 301 and the lower interchangeable cavity positioning ring 302 cooperate with each other to position. The mold can produce multiple specifications and multiple solid tires at the same time. The cavity is interchangeable, the overflow glue is evenly distributed and the pressure field is balanced. Under the same production capacity, time and vulcanization medium energy, the tire production capacity is greatly improved, and the production capacity can even be increased higher on the basis of interchangeability.

[0046] Optionally, the mold also includes a positioning device 4, which includes a positioning bolt 401, a bolt gasket 402 and a cylindrical positioning pin 403.

[0047] Optionally, the mold further includes a positioning auxiliary ring 5, which is arranged at the lower mold positioning hole. The positioning auxiliary ring 5 is detachably connected and is used to prevent the cylindrical positioning pin 403 from colliding with the lower mold body 102 when the mold is positioned, thereby damaging the lower mold body 102.

[0048] In the embodiment of the present application, the function of the positioning device is to ensure that the mold is concentric when opening and closing, avoid misalignment, and affect the appearance quality and overall shape of the tire. Its components include positioning bolts 401, bolt washers 402 and cylindrical positioning pins 403.

[0049] It should be noted that when the mold is positioned, the cylindrical locating pin 403 is prone to collide or scratch with the lower mold positioning hole, and the lower mold body is prone to damage. In order to solve this problem, a positioning auxiliary ring 5 is installed tightly at the lower mold positioning hole to effectively protect the lower mold body 102 from damage during positioning. At the same time, since the positioning auxiliary ring 5 is a wearing part, the positioning auxiliary ring 5 is designed to be detachable for easy replacement.
