[0036] Specifically, such as Figure 1 As shown in the embodiment of this application, a mold with a plastic skeleton sealing strip is provided. The main structure of the mold mainly includes a base plate 100, a pressure plate 200 and a pressing element 300. The base plate 100 is the bottommost position, the pressure plate 200 is disposed on the base plate 100, and the pressing element 300 is disposed on the pressure plate 200, so that the pressure plate 200 is located between the base plate 100 and the pressing element 300.

[0037] Based on the above structure, a fixing groove 110 is provided on the side of the base plate 100 facing the pressure plate 200. The depth of the fixing groove 110 is less than the thickness of the base plate 100, and four fixing grooves 110 are provided in this embodiment of the application, such as... Figures 2-3 As shown, four fixing slots 110 are arranged in parallel to each other. A support member 120 is provided in the fixing slot 110. The shape of the fixing slot 110 matches the shape of the support member 120 so that the support member 120 can be limited by the fixing slot 110, which facilitates the fixing of the support member 120. A first pressing groove 121 is provided on the support member 120 in the direction facing the pressure plate 200. The first pressing groove 121 can limit the installation of the plastic frame.

[0038] The first pressing groove 121 includes multiple pressing groove units 400, and in this embodiment, each support member 120 is provided with two pressing groove units 400. Each pressing groove unit 400 is provided with multiple forming grooves 410, which are used to place plastic skeletons.

[0039] A second pressing groove 210 is arranged on the pressing plate 200 at a position corresponding to the first pressing groove 121, the first pressing groove 121 and the second pressing groove 210 are correspondingly matched, so that a pressing cavity 420 is formed between the first pressing groove 121 and the second pressing groove 210, as shown in Figure 6 and Figure 7 The pressing cavity 420 is used to place a plastic framework, and the first pressing groove 121 and the second pressing groove 210 jointly limit the plastic framework.

[0040] The space size of the pressing cavity 420 is greater than the volume size of the plastic framework, and the space volume left over is used for rubber vulcanization.

[0041] As shown in Figure 4 and Figure 5 The second pressing groove 210 is also provided with a pressing groove unit 400, and the pressing groove unit 400 on the second pressing groove 210 and the pressing groove unit 400 on the first pressing groove 121 are used to limit and install the plastic framework.

[0042] A hopper 220 is arranged on one side of the pressing plate 200 relative to the position of the second pressing groove 210, the depth of the hopper 220 is less than the thickness of the pressing plate 200, and the bottom of the hopper 220 is connected to the second pressing groove 210 through a through hole 230.

[0043] The through hole 230 is connected to the hopper 220 at one end and to the forming groove 410 at the other end.

[0044] The number of the forming grooves 410 corresponds to the number of the through holes 230.

[0045] The through hole 230 is located at one end of the forming groove 410, and when the rubber enters the pressing cavity 420 through the through hole 230, the rubber will flow linearly according to the shape of the pressing cavity 420, facilitating the filling of the pressing cavity 420.

[0046] The pressing plate 200 is also provided with a pressing piece 300, and the pressing piece 300 is provided with a pressing block 310 facing the pressing plate 200, the pressing block 310 is arranged at a position corresponding to the hopper 220, and the shape of the pressing block 310 corresponds to the shape of the hopper 220, so that when the pressing plate 200 and the pressing piece 300 are matched, the pressing block 310 can be placed in the hopper 220, and the extrusion of the rubber by the pressing material enables the rubber to enter the pressing cavity 420 through the through hole 230.

[0047] Based on the above structure, as shown in Figure 3As shown, a first mounting hole 122 is also formed in the support 120, which penetrates the upper and lower sides of the support 120. An installation piece 510 is arranged in the first mounting hole 122, and the length of the installation piece 510 is greater than the thickness of the support 120, so that the installation piece 510 is arranged at the upper and lower ends of the support 120.
