[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] To solve the technical problem of how to effectively improve the use efficiency of the mold, such as Figures 1-4 shown, the following preferred technical solutions are provided:

[0021] A mold for producing machinable microwave absorbing materials includes two symmetric plate-shaped gaskets 2. Between the two plate-shaped gaskets 2, a number of identical U-shaped gaskets 1 are arranged. The cavity formed by the U-shaped gaskets 1 and the plate-shaped gaskets 2 is used for producing sheet materials. A number of positioning holes 3 are respectively provided at the relative positions of the U-shaped gaskets 1 and the plate-shaped gaskets 2. Bolts 4 are inserted into the positioning holes 3. Nuts 5 are threadedly connected to the outer sides of the bolts 4. Rib plates 6 are arranged on the outer sides of the plate-shaped gaskets 2.

[0022] Specifically, according to the thickness of the blank sheet material to be produced, increase or decrease the number of U-shaped gaskets 1. After the number is determined, align and combine the U-shaped gaskets 1 together. Then align and attach the two plate-shaped gaskets 2 to both sides of the combined U-shaped gaskets 1. Here, the rib plates 6 improve the stability during assembly. Then, sequentially insert a number of bolts 4 through a number of positioning holes 3, and use tools to rotate and tighten the nuts 5 on the bolts 4 to fix the U-shaped gaskets 1 and the plate-shaped gaskets 2 to each other, forming an integral mold, and start manufacturing the blank sheet material. The purpose of this design is to adjust the thickness of the mold by adjusting the number of U-shaped gaskets 1 and combining and fixing the two plate-shaped gaskets 2, so as to produce blank sheet materials of different thicknesses and improve the use efficiency of the mold.

[0023] Further, as Figures 1-4 shown, the following preferred technical solutions are provided:

[0024] The U-shaped gaskets 1 and the plate-shaped gaskets 2 are of matching sizes. The purpose of this design is to ensure the rationality of the structure.

[0025] Further, as Figure 1 shown, the following preferred technical solutions are provided:

[0026] Two symmetric rib plates 6 are fixedly connected to the lower ends of the outer sides of the plate-shaped gaskets 2. The rib plates 6 have a certain weight. The purpose of this design is to improve the stability of the plate-shaped gaskets 2 during assembly through the rib plates 6.

[0027] Further, as Figure 1 shown, the following preferred technical solutions are provided:

[0028] Rectangular frames 7 are fixedly connected to the middle parts of both sides of one of the plate-shaped gaskets 2. The purpose of this design is to quickly align and combine the U-shaped gaskets 1 and the two sides of the plate-shaped gaskets 2 against the inner sides of the rectangular frames 7, playing a positioning role.

[0029] Further, as Figure 1 and Figure 2 shown, the following preferred technical solutions are provided:

[0030] A fixing rod 8 is fixedly connected to the inner side wall of the rectangular frame 7. A slider 10 is slidably connected to the outer side of the fixing rod 8. The slider 10 is in contact connection with the inner side of the rectangular frame 7. A spring 9 is tightly connected between the slider 10 and the inner side wall of the rectangular frame 7. The spring 9 is sleeved on the outer side of the fixing rod 8. The purpose of this design is to ensure that the slider 10 moves linearly along the axis direction of the fixing rod 8 under force.

[0031] Furthermore, as Figure 1 and Figure 2 shown, the following preferred technical solutions are provided:

[0032] A rectangular groove 11 is opened at the upper end of the slider 10. A limiting plate 12 is hinged to the inner side of the rectangular groove 11 through a positioning pin. The purpose of this design is that after the U-shaped gasket 1 and the plate-shaped gasket 2 are combined, the slider 10 is moved to stretch the spring 9 and rotate the limiting plate 12, so that the limiting plate 12 is pressed against the outer side of the plate-shaped gasket 2 due to the restoring deformation tension of the spring 9, and the U-shaped gasket 1 and the plate-shaped gasket 2 as a whole are initially fixed, facilitating the further fixing by the subsequent bolt 4.

[0033] To sum up: According to the thickness of the blank sheet to be produced, increase or decrease the number of U-shaped gaskets 1. After determining the number, align and combine the U-shaped gaskets 1 together. Then, align and attach the two plate-shaped gaskets 2 to both sides of the combined U-shaped gaskets 1. Here, the rib plate 6 improves the stability during assembly. Then, sequentially pass a plurality of bolts 4 through a number of positioning holes 3, and use a tool to rotate and tighten the nuts 5 on the bolts 4 to fix the U-shaped gaskets 1 and the plate-shaped gaskets 2 to each other, forming a whole mold, and start manufacturing the blank sheet. The purpose of this design is that by adjusting the number of U-shaped gaskets 1 and the combination and fixation of the two plate-shaped gaskets 2, the thickness of the mold can be adjusted, so that blank sheets of different thicknesses can be produced, improving the use efficiency of the mold.
