[0024] The following will describe the implementation manners of the present application in detail in conjunction with the accompanying drawings and embodiments, so as to fully understand the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects and implement accordingly.

[0025] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0026] Figures 1 - 5 For an embodiment of the present utility model, the specific problem addressed by this specific embodiment is as follows: The existing external vacuum sealing device for molds is a whole design of a polygon frame, which is overall bulky. However, according to different operation requirements, it is necessary to replace the tooling. In the actual operation process, on the one hand, the sealing frame needs to be disassembled as a whole, which is not convenient for disassembly and assembly and is extremely dangerous. On the other hand, once the sealing frame is damaged, the replacement cost is also high. Based on the foregoing problems, this solution describes an external vacuum sealing device for molds that is convenient for disassembly and assembly. By connecting a number of sealing unit plates 2, the integral polygon sealing frame is changed into a combined type, and both sides can be designed to be individually disassembled or assembled, making the disassembly and assembly simpler and more convenient, which not only improves the work replacement efficiency but also reduces the cost.

[0027] Embodiment 1

[0028] An externally placed vacuum sealing device for a mold that is convenient for disassembly and assembly, comprising an external table 1, on which several sealing unit plates 2 for establishing a rectangular working area are installed. The sealing unit plates 2 include straight plates 21 and arc-shaped broken plates 22 installed at both ends of the straight plates 21. The number of sealing unit plates 2 is not less than 4. In this embodiment, 4 sealing unit plates 2 are taken as an example for illustration. Arc-shaped grooves 23 for internally placing a sealing rubber strip 3 are formed on all 4 sealing unit plates 2. By placing a complete sealing rubber strip 3 in the 4 arc-shaped grooves 23, and the set length of the sealing rubber strip 3 is equal to the sum of the lengths of the arc-shaped grooves 23 of the 4 sealing unit plates 2. Thus, when the sealing rubber strip 3 is placed in the arc-shaped groove 23, the 4 sealing unit plates 2 are assembled into one body by using the sealing rubber strip 3, enhancing their stability when placed on the external table 1. The depth of the arc-shaped groove 23 is equal to half of the structural height of the sealing rubber strip 3, which is convenient for the internal embedding and removal of the sealing rubber strip 3, and further convenient for the combination and separation of the 4 sealing unit plates 2, reducing the disassembly and assembly cost and enhancing the disassembly and assembly convenience. And in order to enhance the stability of the sealing unit plates 2 on the external table 1, a limiting rod 5 installed on the external table 1 is also provided on one side of the sealing unit plates 2. When removing the sealing unit plates 2, first remove the sealing rubber strip 3, and then lift the sealing unit plates 2 upward and over the limiting rod 5 and withdraw them outside the external table 1. After all or part of the sealing unit plates 2 on the external table 1 are removed, the purpose of exposing the tooling can be achieved. Take out and replace the tooling from the removed sealing unit plates 2, that is, the requirement for replacing the tooling can be met, and different working requirements can be satisfied.

[0029] Embodiment Two

[0030] In order to enhance the stability between adjacent sealing unit plates 2 under the action of the sealing rubber strip 3 and the limiting rod 5, in this embodiment, a stable state is established by setting a limiting member 4;

[0031] The position-limiting member 4 includes a mounting column 41 mounted on the external platform 1, and the mounting column 41 is arranged at the connection of two adjacent sealing unit plates 2. Two symmetrical position-limiting grooves 42 are arranged at both ends of the mounting column 41, and the position-limiting grooves 42 are ring-shaped, and a position-limiting shaft 43 mounted on the bottom surface of the arc-shaped end plate is adapted to be arranged in the position-limiting groove 42. An inner groove adapted to the limiting middle groove 42 is opened at the installation position of the limiting shaft 43, and an extension groove 46 penetrating the inner groove and adapted to the installation column 41 is opened on two adjacent sealing unit plates 2. The extension length of the extension groove 46 is equal to the height of the installation column 41. By utilizing the insertion or removal of the limiting shaft 43 in the limiting middle groove 42, when removing the sealing unit plate 2, first remove the sealing rubber strip 3, and then lift the sealing unit plate 2. When its height satisfies the limit shaft 43 to disengage from the limiting middle groove 42, and then after crossing the limit rod 5, the sealing unit plate 2 can be removed from the external platform 1, thereby achieving the same purpose as in Example 1, exposing the tooling and then replacing the tooling.

[0032] In addition, the above-mentioned limit member 4 in this embodiment may also have another alternative scheme. Specifically, the limit member 4 includes a limit groove 44 installed at one end of the sealing unit plate 2, and the end of the sealing unit plate 2 facing away from the installation surface of the limit groove 44 is provided with a limit column 45 complementary to the limit groove 44. The limit groove 44 and the limit column 45 are both arranged at the lower end of the side wall of the sealing unit plate 2, and the limit groove 44 is protruded from the sealing unit plate 2. Through this arrangement, the arrangement of the installation column 41 and the limit middle groove 42 is reduced, which can reduce the processing cost of the sealing unit.
