[0046] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the above drawings.

[0047] In this application, the terms "comprises", "includes", "has" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0048] In the present application, the term "and / or" is a description of the association relationship of associated objects, indicating that three relationships may exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent: the existence of a centrifugal vortex magnetic pump alone, the existence of a centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump at the same time, and the existence of a centrifugal vortex magnetic pump alone. In addition, the character " / " in the present application generally indicates that the objects associated before and after are in an "and / or" relationship.

[0049] In the present application, the terms "connect", "combine", "couple", and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, direct connection refers to two parts or components being connected together without the need for an intermediate piece, and indirect connection refers to two parts or components being connected to at least one intermediate piece respectively, and the two parts or components being connected via the intermediate piece. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0050] In this application, it will be understood by those skilled in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerance caused by manufacturing, assembly, and use associated with a specific value, etc. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0051] In this application, it will be understood by those skilled in the art that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0052] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0053] Based on the above, the existing pressurizing device generally includes a booster cylinder arranged on a base, which pushes the lower support plate upward to apply a certain force to the lower mold, thereby providing the mold with the clamping force required for vulcanizing the tire. However, when the booster cylinder is applied with force, it is not only necessary to provide the mold with the clamping force required for vulcanizing the tire, but also to overcome the gravity of the lower support plate, the mold and the tire, thereby placing high performance requirements on the booster cylinder and having a high cost of use. In addition, the lower support plate is pushed by the booster cylinder to achieve mold closing, so that the mold after mold closing is always located on the lower support plate. When the mold needs to be replaced later, the booster cylinder needs to drive the lower support plate to descend to provide operating space for replacing the mold, but the upper side of the mold is always blocked by the components used to fix the upper mold, so that the operating space is relatively narrow and inconvenient to operate.

[0054] To solve the above problems, please refer to Figures 1 to 3 The present embodiment provides a pressurizing device, which is used to provide a clamping force to the mold. The pressurizing device includes a base 1, a moving groove 11, a support plate 2, a reset groove 12, a lower pull rod 3, a nitrogen supply assembly, an upper pull rod 4 and a crossbeam 5.

[0055] The base 1 is configured to carry the mold. The base 1 is a prior art. The base 1 includes a plurality of components used in conjunction with the mold, such as a tooling for fixing the mold, which will not be described in detail in this embodiment. The motion groove 11 is arranged on the base 1 along the vertical direction, and the lower side of the motion groove 11 is arranged in an open state. The support plate 2 includes a sliding portion 22 slidably embedded in the motion groove 11, and the sliding portion 22 is sealedly connected to the groove wall of the motion groove 11, and a motion cavity 13 is formed between the sliding portion 22 and the groove wall of the motion groove 11. The reset groove 12 is vertically penetrated and opened on the base 1. The lower pull rod 3 penetrates the reset groove 12 and slidably cooperates with the reset groove 12. The lower pull rod 3 is sealedly connected to the groove wall of the reset groove 12, and a reset cavity 14 is formed between the lower pull rod 3 and the groove wall of the reset groove 12. The support plate 2 includes a connecting portion 23 connected to the lower pull rod 3. In this embodiment, the sliding portion 22 is fastened to the connecting portion 23 by bolts, and the support plate 2 is formed by the sliding portion 22 and the connecting portion 23 .

[0056] The nitrogen supply assembly is configured to supply nitrogen into the moving cavity 13 to push the support plate 2 to move downward along the moving groove 11, and is configured to supply nitrogen into the reset cavity 14 to push the lower pull rod 3 to move upward along the reset groove 12. The upper pull rod 4 is detachably connected to the upper end of the lower pull rod 3. The crossbeam 5 is arranged on the upper pull rod 4, and the crossbeam 5 can abut against the upper side of the mold. It should be noted that, in this embodiment, a vent hole 24 is connected and opened on the sliding portion 22 and the connecting portion 23, and the nitrogen supplied by the nitrogen supply assembly is input into the moving cavity 13 through the vent hole 24.

[0057] The process of applying the clamping force: first, the nitrogen supply component supplies nitrogen into the moving cavity 13 to push the support plate 2 to move downward along the moving groove 11, and then the support plate 2 drives the lower pull rod 3 to move downward, and then the lower pull rod 3 applies pressure to the cross beam 5 through the upper pull rod 4, and then the cross beam 5 transmits the pressure to the upper side of the mold on the base 1, thereby providing the clamping force to the mold. At this point, the clamping force application is completed.

[0058] Mold changing process: first, the nitrogen supply assembly supplies nitrogen into the reset chamber 14 to push the lower pull rod 3 to move upward along the reset groove 12, so that the crossbeam 5 no longer applies pressure to the upper side of the mold. Then, the upper pull rod 4 is removed from the lower pull rod 3, that is, the crossbeam 5 can be removed from above the mold, and then the mold is removed from the base 1, and then another mold is placed on the base 1, and finally the upper pull rod 4 is assembled to the lower pull rod 3, and the mold changing is completed.

[0059] It is understandable that by applying pressure to the crossbeam 5, it is possible to provide a clamping force from the upper side of the mold to the mold. Compared with the prior art method of applying pressure to the lower side of the mold by a booster cylinder, there is no need to overcome the gravity of the mold and related components, thereby reducing the performance requirements of the components that provide pressure, and thus reducing the cost of use. It is also understandable that during the mold change process, the upper pull rod 4 can be disassembled from the lower pull rod 3, so that the upper side of the mold will not be blocked, thereby providing a larger operating space for replacing the mold, which is convenient for operation. In addition, the driving force is provided by the nitrogen supply component. Compared with the existing pressurizing device providing the driving force through the cylinder, nitrogen is a clean energy source, which is easy to obtain and does not pollute the environment, and has a lower cost of use. In addition, the traditional oil cylinder and hydraulic station can be eliminated to avoid the risk of hydraulic oil leakage, and the equipment and environment are cleaner. In addition, there is no relative movement between the central mechanism and the base of the pressurizing device, which can ensure the operating accuracy of the central mechanism.

[0060] It should be noted that the nitrogen supply assembly and its working principle are both existing technologies, so they are not described in detail in this embodiment.

[0061] Preferably, the motion groove 11 is annularly arranged, and the support plate 2 is similar in shape to the motion groove 11. A plurality of lower pull rods 3 are arranged, and the plurality of lower pull rods 3 are evenly distributed on the support plate 2. The number of reset grooves 12 and upper pull rods 4 corresponds to the number of lower pull rods 3, and the plurality of upper pull rods 4 are respectively connected to a plurality of positions on the circumference of the cross beam 5. With such an arrangement, the plurality of lower pull rods 3 can be driven to move downward at the same time by the support plate 2, thereby driving the plurality of upper pull rods 4 to move downward, and then the plurality of upper pull rods 4 can apply pressure to a plurality of positions of the cross beam 5 at the same time, that is, can apply pressure to a plurality of positions on the upper side of the mold at the same time, so that the clamping force provided to the mold is more uniform.

[0062] To prevent the support plate 2 from being disengaged from the movement slot 11 during use and causing inconvenience, the pressurizing device further includes a limiter 6 which is detachably disposed on the lower pull rod 3 and is configured to limit the maximum movement distance of the lower pull rod 3 .

[0063] In addition, in this embodiment, a sealing ring 21 is used to seal between the support plate 2 and the moving groove 11, and the sealing ring 21 is a wearing part and needs to be replaced regularly. It can be understood that the limiter 6 is detachably arranged on the lower pull rod 3, so that the limiter 6 can be removed when the sealing groove needs to be replaced.

[0064] Specifically, the limiting member 6 includes a limiting ring 61 and a fixing member 62. The limiting ring 61 has an opening, and a mounting ring groove is provided on the lower pull rod 3, and the limiting ring 61 is embedded in the mounting ring groove. The fixing member 62 is configured to lock the opening of the limiting ring 61. During the process of loading and unloading the limiting ring 61, the two ends of the limiting ring 61 are pulled outward to deform it, so that the opening can be enlarged, thereby facilitating the embedding of the limiting ring 61 into the mounting ring groove or removing the limiting ring 61 from the mounting ring groove. It should be noted that the fixing member 62 can select any fastening structure in the prior art, such as bolts and nuts.

[0065] It should be added that the movement distance of the upper pull rod 4 is limited by the movement distance of the support plate 2, that is, the movement distance of the upper pull rod 4 is limited by the depth of the movement groove 11. However, in order to ensure production efficiency, the movement groove 11 will be set shallower to shorten the movement path and more efficiently apply pressure to the mold, which will cause the pressure-applying device to be unable to close multiple molds with large height differences.

[0066] In order to make the pressurizing device applicable to molds of various heights, the pressurizing device further includes an adjusting component 7, which is arranged between the upper pull rod 4 and the crossbeam 5, and is configured to adjust the position of the crossbeam 5 on the upper pull rod 4. In this way, the distance between the crossbeam 5 and the mold can be adjusted, so that pressure can be applied to molds of different heights through the crossbeam 5.

[0067] Specifically, the adjustment component 7 includes a clamp 71 and a plurality of gaskets 72, and the clamp 71 is detachably arranged on the upper end of the upper pull rod 4. A plurality of gaskets 72 can be stacked and sleeved on the upper pull rod 4, and are located between the clamp 71 and the crossbeam 5. It can be understood that the position of the crossbeam 5 is adjusted by the number of stacked gaskets 72, and the structure is simple and the use cost is low. It should be noted that the clamp 71 is a prior art and will not be described in detail. It should also be noted that the model of the gasket 72 can be selected according to the actual usage scenario, and this embodiment does not make specific requirements and restrictions on this.

[0068] Preferably, the pressurizing device further includes a quick release assembly 8, which is arranged between the lower pull rod 3 and the upper pull rod 4 to control the connection or disconnection of the lower pull rod 3 and the upper pull rod 4. Such an arrangement helps to improve the efficiency of mold change. In this embodiment, the quick release assembly 8 includes a plum blossom head 81 and a plum blossom groove 82, and the plum blossom head 81 is arranged at the lower end of the upper pull rod 4. The plum blossom groove 82 is arranged at the upper end of the lower pull rod 3, and the plum blossom head 81 and the plum blossom groove 82 can be meshed and connected. It should be noted that the quick-release structure composed of the plum blossom head 81 and the plum blossom groove 82 is a prior art. Specifically, after the plum blossom head 81 is inserted into the plum blossom groove 82, the plum blossom head 81 or the plum blossom groove 82 is rotated by a preset angle so that the plum blossom head 81 and the plum blossom groove 82 are engaged, thereby realizing the connection between the two. Conversely, the plum blossom head 81 or the plum blossom groove 82 is rotated so that the plum blossom head 81 and the plum blossom groove 82 are disengaged, that is, the plum blossom head 81 can be taken out of the plum blossom groove 82, thereby realizing the separation of the two.

[0069] Further, the lower pull rod 3 is rotatably arranged on the base 1, and the lower pull rod 3 moves upward along the reset groove 12 to the initial position, and an adjustment gap is formed between the plum blossom head 81 and the plum blossom groove 82 to ensure that the lower pull rod 3 can be rotated. Such a setting makes it easier to rotate the reset member, that is, it makes it easier to rotate the plum blossom groove 82, and the operation is convenient. It should be noted that the setting of the adjustment gap is well known to those skilled in the art and will not be described in detail.

[0070] This embodiment also provides a vulcanizer, which includes the above-mentioned pressure device and a mold, and the pressure device is used to provide a clamping force to the mold. It can be understood that the vulcanizer including the above-mentioned pressure device has low use cost and is easy to change molds.

[0071] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
